Nitrogen(N) is a critical factor influencing yield and quality of triticale. To analyze the effects of N accumulation and distribution on N use efficiency(NUE) at different growth stages(tillering, jointing and heading) of triticale, a pot experiment with three N fertilization rates [0(zero-N), 0.033 g(N)·kg-1(low-N) and 0.066 g(N)·kg-1(normal-N)] and three triticale varieties [two high NUE(‘Clxt82', ‘PI429186') and one low NUE(‘Clxt74')] was carried out. The distribution of N in plant organs, and contents of different N forms were analyzed at various growth stages. The results showed that high NUE triticale varieties were advantages in low N conditions. The differences in biomass between high and low NUE varieties gradually decreased with increasing N fertilization rates at heading stage. Above-ground biomass of ‘Clxt82' was respectively 1.55 times, 1.19 times and 1.06 times that of ‘Clxt74' under zero-N, low-N and normal-N treatments. Similarly, above-ground biomass of ‘PI429186' was respectively 1.79 times, 1.35 times and 1.30 times that of ‘Clxt74' under zero-N, low-N and normal-N treatments. N accumulation increased significantly with increasing N fertilization rates at different growth stages. Under low-N and normal-N treatments, N accumulation in both high NUE varieties was significantly higher than that in low NUE variety at tillering and jointing stages. However, no significant difference was noted between the varieties at heading stage. Allocation ratio of N in plant leaves and ears decreased with increasing N fertilization rates and the reverse was the case for plant stems. At tillering and jointing stages, N allocation ratios of stems of high NUE varieties were less than that of low NUE variety, and for leaves it was reverse. At heading stage, N allocation ratio of ears of high NUE varieties was higher than in low NUE varieties and the reverse was the case for leaves. Contents of different forms of N increased with increasing N fertilization rates at various growth stages. At jointing stage, assimilable N(AN) contents in ‘Clxt82' and ‘PI429186' leaves were respectively 1.31 times and 1.76 times that in ‘Clxt74' under zero-N treatment, and 1.12 times and 1.35 times under low-N treatment. Then structural N(SN) contents were respectively 86.12% and 64.01%, and 80.82% and 71.51% that of ‘Clxt74'. At heading stage, AN content in ‘Clxt82' and ‘PI429186' leaves were respectively 1.01 times and 1.11 times that of ‘Clxt74' under zero-N treatment, and 1.04 times and 1.13 times under low-N treatment. Also SN content were respectively 74.99% and 63.08%, and 75.78% and 62.84% that of ‘Clxt74'. However, functional N(FN) content was not significantly different for the varieties at various growth stages. High NUE varieties maintained N utilization and N cycle by reducing SN content and increasing AN content.

The Three Gorges Reservoir Area is a key control region of eco-environmental construction in China. However, how to achieve agro-economic development and control agricultural non-point source pollution in the region have emerged as difficult issues in recent years. To verify the coupling process of agricultural eco-economic system under emission mitigation and sink enhancement, data from the Zhong County(a typical non-point source pollution control district in the Three Gorges Reservoir Area) was used to develop eco-agriculture and non-point source pollution control. Then an equation-driven model of the construction structure was studied in terms of the interrelationship and interaction paths of the various elements of agricultural resources, agricultural development and agricultrual eco-economic coupling system in the Three Gorges Reservoir Aarea of Zhong County under the backdrop of emission mitigation and sink enhancement of non-point source pollution policies and measures. The paper put forward 6 basic assumptions based on 4 latent variables(emission mitigation and sink enhancement of non-point source pollution policies and measures, agricultural resources, agricultural development and coupling degree of agricultural eco-economic system) and the corresponding observation variables. Based on these elements, the paper designed a coupling model of the agricultural eco-economic system. The empirical results revealed that the path coefficient of the interrelationship between agricultural non-point source pollution control measures and agricultural resources utilization was 0.79. This suggested that the government's emission mitigation and sink enhancement measures promoted rational utilization of agricultural resources in the region. The path coefficient of the interactive relationship between emission mitigation and sink enhancement measures of agricultrual non-point source pollution and agricultural development was 0.80. This also suggested that the measures and policies were strong incentive for agricultural development in the study area. The path coefficient of the relationship between agricultural development and resources utilization was 0.77, indicating that agro-economic development in the region was based on reasonable agricultural resources utilization. Emission mitigation and sink enhancement measures positively influenced the coupling process of agricultural eco-economic system. The path coefficient was 0.85, which suggested that the measures in the study area significantly improved the coupling process. The utilization of agricultural resources and development positively influenced the process of agricultural eco-economic system coupling. The respective path coefficients were 0.91 and 0.89, indicating that the coupling process of agro-industry and agro-resources system conformed to the nature of agricultural development.

Placements of soil moisture sensor have been key considerations in obtaining representative soil water content in crop root zones for irrigation schedules. In this article, the distribution of soil water content in the wetted volume from a line source was studied in drip irrigated tomato in solar greenhouse condition. Through comparison of tomato water consumption determined from measured water content by moisture sensors at different locations, suitable placements of sensors were discussed. The results indicated that irrigation quota range of 14 25 mm increased soil water content in the 0 40 cm soil layer, and daily mean soil water content in wetted soil volume was 75% 100% field capacity throughout tomato growth season. Wetted soil volumes generated by adjacent emitters along the drip lines fully overlapped after several sequential irrigation events, forming lateral zones with approximately uniform distribution of water content around the drip lines. There was no significant difference between mean soil water content along the depth of 0 40 cm layer. The variation tendency of soil water content with time at different horizontal locations from drip lines was synchronous in character, without any obvious hysteresis quality. Assuming that the 0 40 cm layer was the root zone with 80% root concentrated, an irrigation quota range of 14 25 mm caused deep percolation from the bottom of the root zone with a certain spatial variability. Seasonal deep percolation accounted for 13% of irrigation amount during tomato growth season. The differences in tomato water consumption at different locations from drip lines were within 10%, except for the seedling and blossom fruiting stages. The experimental results suggested that high frequency drip irrigation sustained suitable soil water condition in the root zone. One profile of soil water content measured in the proximity of drip lines was adequate for the proper estimation of water consumption of drip irrigated tomato in solar greenhouse conditions.
