In order to study the effects of different amount of functional materials (FM) on pearl oil apricot, the study set up 0 g (control), 50 g (FM50), 200 g (FM200) and 300 g (FM300) of functional materials, and mixed with 2 kg of compound fertilizer as the base fertilizer. The growth and physiological indexes of pearl oil apricot and soil physicochemical properties were measured. Results showed that FM treatment significantly improved the pollen viability especially under FM300 treatment. FM200 and FM300 treatments significantly improved leaf carotenoids, anther size and anther quality of 100 seeds compared with the control. The anther width was significantly increased by 0.13 mm at FM300. However, physiological indexes such as filament length, anther length, pistil development type, hundred leaves length, hundred leaves width, hundred leaves thickness, hundred leaves weight and pollen fullness were not affected by FM. It can be seen that FM had a greater effect on growth and physiology indicators of pearl oil apricot, while the effect on soil physicochemical properties was smaller.

Municipal sewage sludge has a potential for widespread application on land, but the implementation of new standards for the agricultural use of sludge in China support a cautious approach. The organic matter, nutrients, and heavy metals in sewage sludge from four municipal wastewater treatment plants in Jiujiang City of China were continuously monitored. The feasibility for its land use was analyzed from three aspects such as sludge nutrients, heavy metal pollution levels, and potential ecological risks in soil. The average content of Cd, Cu, Zn, Cr, Ni, Pb, Hg and As in the sludge of Jiujiang City are 1.85, 305.25, 764.48, 170.57, 42.45, 42.27, 0.59, 28.79 mg∙kg-1, which are less than or close to mean value of heavy metals in China (except As), and all meet the minimum standards of heavy metal content in the sludge according to Chinese Quality of sludge from municipal wastewater treatment plant (GB24188-2009). The maximum content of Cu, Zn, Cr, and As exceed the control standards of pollutants in sludge for agricultural use, and the maximum value of Cu and Cr are close to the limit of landscaping standards. The average contents of organic matter, total nitrogen, total phosphorus, total potassium, and total nutrients in sludge are 385.16, 34.14, 11.05, 7.87, 53.06 g∙kg-1, respectively. The organic matter content meets the limit value (no less than 200 g∙kg-1) of Chinese Control standards of pollutants in sludge for agricultural use (GB 4284-2018), and the total nutrients content meets certain content limit (no less than 40 g∙kg-1) of total nutrients in China’s organic fertilizer. The single-factor pollution index and Nemerow’s synthetic pollution index methods were used to assess the pollution of heavy metals. The heavy metal pollution indexes (PI) are in descending order: Cd > Cu > Zn > Cr > As > Ni > Pb > Hg. The PI shows that Cd and Cu are in strong pollution level, Zn is in moderate pollution level, and As, Ni, Pb, Hg are in absolute safe level. The potential ecological risk levels of heavy metal are ranked in the following order: Cd> Cu> As> Ni> Zn> Cr > Pb. The monomial potential ecological risk coefficients reveal that Cd is in extremely strong ecological risk, Cu is in medium ecological risk and other heavy metals are in slight ecological risk. The results indicate that Cd and Cu are the main contributors to the pollution and potential ecological risks of heavy metals in soil, to which more attention should be paid during sludge disposal. Being rich in organic matter and inorganic plant nutrients，sewage sludge in Jiujiang City may be widely used on soil, but availability of potential toxic metals exceeding the limit value often restricts its uses. Before being harmlessly treated, the sludge in Jiujiang City should not be used on agricultural land and may be applied with highly caution on landscaping and land improvement, but it can be used as cover materials for co-landfilling.

In the rapid development of social economy and science and technology, the construction management of power transmission and transformation project began to widely use modern science and technology theory, the most representative of which is remote sensing technology. According to the data obtained by UAV digital policy image and digital surface model, soil and water conservation measures and engineering prevention and control monitoring are proposed in the integrated analysis and calculation research, which can provide technical support for the construction management of power transmission and transformation projects. Therefore, on the basis of understanding the technical content of transmission and transformation engineering line construction, this paper mainly explores the transmission and transformation engineering monitoring system based on low-altitude remote sensing technology of drones and builds an intelligent transmission and transformation engineering settlement audit platform according to the current development status of transmission and transformation engineering completion settlement audit.

This experiment compared the effects of a novel rice establishment method with traditional machine-transplanting carpet seedling (MTCS). The new method (RSSR) is a modified direct seeding method, which manually or drone aerial sowed the seeds into the field before wheat harvesting, then cover the seeds with wheat straw after harvesting. Samples were measured to compare the difference of plant height, stem width, and panicle length, straw biomass, effective panicle, spikelets per panicle, panicle weight, 100 grain weight, and grain yield. The results showed that compared with MTCS, RSSR can increase rice growth indicators and yield indicators, but had no significant difference. Only the panicle weight of RSSR was significantly higher than that of MTCS. Furthermore, the management of RSSR was more convenient, which can save water, herbicide and human labor. Thus, this new rice establishment method can be introduced to the wheat-rice and rapeseed-rice rotation area.

In oil and gas exploration and development, the complex working conditions of high temperature and high pressure are increasing, and the strength decline of silica-cement often occurs under such conditions. In this work, the metakaolin influence on the mechanical properties and micro-structure of silica-cement at 240 ℃ and 21 MPa condition is comprehensively studied. XRD technique investigated the chemical composition of cement crystal phase, and SEM observed the micro-morphology of high temperature cement. Results showed that the loading metakaolin has reduced porosity by 12.86%, air permeability while greatly increased nanopore (＜50nm) by 36.47% and increased nanopore (＜10 nm) by 10.34%. Thus, the cement permeability reduced greatly or its anti-channelling enhanced, that is, such results improved the comprehensive performance of cement slurry. These observations, combined with the previously reported the remarkable enhancement of the MK cement compressive strength, represent a major step toward the development of strength retrogression-resistant material at high temperature.

The principle of energy storage promoting new energy consumption was analyzed and the role of energy storage in new energy consumption under different installed penetration rates of new energy was rearranged in this article. In addition, a detailed analysis was conducted on the limitations of daily regulated energy storage on new energy consumption with data from a major new energy province in northwest China as an example. The case results revealed that in case of a high penetration rate of new energy, there will be a gradual weakening in the improvement effect of increasing daily regulated energy storage on new energy consumption and there will be a gradual “saturation” in the utilization rate of new energy accompanied by the increase of energy storage scale. Nonetheless, measures such as the flexible transformation of thermal power and increase of external transmission channels to promote consumption are not related to the “saturation effect”. The conclusion of this article can be as a reference for other countries and regions in the allocation of flexible resources for promoting new energy consumption.

According to the general steps of comprehensive utilization of each type of bulk industrial solid waste, including fly ash, coal gangue, tailings, smelting slag, industrial by-product gypsum, and red mud, we construct the testing standards system for comprehensive utilization of bulk industrial solid waste in China. The standards system, according to the lifecycle stage of "raw materials - pre-treatment - processing - forming products - using products", can be divided into 5 standard subsystems, namely a subsystem of physical property testing standards for raw materials, a subsystem of chemical property testing standards, a subsystem of process testing standards, a subsystem of the product quality performance testing standards and a subsystem of the environmental impact testing standards. The standards system provide top-level guidance for the implementation and development of comprehensive utilization testing methods for bulk industrial solid waste.

To study the effects of different treatments on the germination characteristics of Salvia miltiorrhiza seed, Salvia miltiorrhiza seeds were treated by fludioxonil and carbendazim, and were studied with different thickness of covering soil. The results showed that with the increase of soil cover thickness, the germination rate of Salvia miltiorrhiza seeds significantly decreased. The thickness of covering soil was 0 cm, the germination of Salvia miltiorrhiza seeds was the best and the germination rate was 42.08%. When the thickness of covering soil was 1.0 cm, the germination rate of Salvia miltiorrhiza seeds significantly decreased, only 2.91%, which was 93.08% lower than the control. The appropriate concentration of seed coating agent can improve the germination rate of Salvia miltiorrhiza seeds. When the soil thickness was 0 cm+1.25 g∙L-1 fludioxonil, the best germination effect of Salvia miltiorrhiza seeds was observed, and the germination rate was 59.17%, which increased 40.61% compared to 0 cm soil alone. The germination rate of Salvia miltiorrhiza seeds treated with 0 cm+2.5 g∙L-1 fludioxonil was only 13.75%, which was 28.33% lower than the germinationg rate with the soil thickness of 0 cm alone. There was no significant difference in the germination rate of Salvia miltiorrhiza seeds treated with 0.05% carbendazim compared with the control group; The germination rate of Salvia miltiorrhiza seeds treated with 0.1% carbendazim was significantly lower than that of the control group covered with 0 cm soil alone. In summary, The best germination level of Salvia miltiorrhiza seed was the cover thickness of 0 cm soil and 1.25 g ∙ L-1 concentration of fludioxonil, ( 0 cm+1.25 g∙L-1). The treatment of seeds with 2.5 g∙L-1 concentration of chloramphenicol showed a significant inhibitory effect on the germination of Salvia miltiorrhiza seeds. In conclusion, Salvia miltiorrhiza seeds treated with 1.25 g∙L-1 concentration of fludioxonil and 0 cm covered soil, the germination rate, germination potential, and germination index are 59.17%, 51.67%, and 14.27, respectively, which increased by 40.61%, 61.07%, 77.28% compared with the soil of 0 cm alone. It is suggested that breeding of Salvia miltiorrhiza seeds should be carried out on land with the appropriate concentration of fludioxonil.
为研究不同处理对丹参种子萌发特性的影响，用氟啶虫酰胺和多菌灵处理丹参种子，并在不同覆土厚度下进行研究。结果表明，随着覆土厚度的增加，丹参种子的发芽率明显降低。覆盖土厚度为 0 cm 时，丹参种子的发芽情况最好，发芽率为 42.08%。当覆土厚度为 1.0 cm 时，丹参种子的发芽率明显下降，仅为 2.91%，比对照低 93.08%。适当浓度的种衣剂可以提高丹参种子的发芽率。当土壤厚度为 0 cm+1.25 g∙L-1 氟啶虫酰胺时，丹参种子的发芽效果最好，发芽率为 59.17%，比单独使用 0 cm 土壤时提高了 40.61%。经 0 cm+2.5 g∙L-1 氟啶虫酰胺处理的丹参种子的发芽率仅为 13.75%，比土壤厚度为 0 cm 时的发芽率低 28.33%。使用 0.05% 多菌灵处理的丹参种子的发芽率与对照组相比无明显差异；使用 0.1% 多菌灵处理的丹参种子的发芽率明显低于仅覆盖 0 cm 厚土壤的对照组。综上所述，丹参种子的最佳发芽水平是覆盖厚度为 0 cm 的土壤和 1.25 g∙L-1 浓度的氟啶虫酰胺，即（0 cm+1.25 g∙L-1）。用 2.5 g∙L-1 浓度的氯霉素处理种子对丹参种子的萌发有明显的抑制作用。综上所述，丹参种子经 1.25 g∙L-1 浓度的氟啶虫酰胺和 0 cm 覆土处理后，发芽率、发芽势、发芽指数分别为 59.17%、51.67%、14.27，与单独 0 cm 覆土相比，分别提高了 40.61%、61.07%、77.28%。 建议在施用适当浓度氟啶虫腈的土地上培育丹参种子。
