摘要

本文总结了三年土壤保险除草剂和微量肥料量子钼螯合物对大豆侵染和产量的可行性和有效性研究结果。结果表明,大豆农藓病形成了以双子叶小杂草为主的混合型侵染。施用60 d后,除杂草效率为75.5%。施用保险除草剂Korum (1.5 l / ha +表面活性剂甲氧膦1.0 l / ha)可使大豆杂草减少89.5%。土壤除草剂Frontier Optima (1.0 l/ha)和保险除草剂Corum (1.5 l/ha +表面活性剂Metolate 1.0 l/ha)的持续施用,与存在自然堵塞背景的对照相比,可以消灭高达98.9%的杂草。上述除草剂与浓钼微肥量子螯合钼配合施用,为大豆植株的生长发育提供了最佳条件。施用微肥的地区不良植被数量没有变化。而杂草的干质量则降低了17.1 ~ 32.4%。在三年的研究中,施用除草剂的大豆品种的平均产量明显高于对照品种。施用Frontier Optima除草剂(1.0 l/ha)时为2.26 t/ha,施用Korum除草剂(1.5 l/ha +表面活性剂Metolate 1.0 l/ha)时为2.75 t/ha。连续施用Frontier Optima (1.0 l/ha)和Corum (1.5 l/ha +表面活性剂Metolate 1.0 l/ha)时,大豆产量最高,达2.94 t/ha。连续施用除草剂Frontier Optima (1.0 l/ha)和Corum (1.5 l/ha +表面活性剂Metolate 1.0 l/ha)品种的蛋白质和油脂含量最高,分别为33.3%和22.5%。在除草剂背景下,施用量子钼螯合物微肥可使1000粒种子重量增加2 g,蛋白质和油脂含量增加0.6%。

EVALUATION OF THE INFLUENCE OF HERBICIDES AND FERTILIZER ON POLLUTION AND YIELD OF SOYBEAN
The article summarizes the results of a three-year study on the feasibility and effectiveness of the use of herbicides of soil and insurance action and microfertilizer Quantum - Molybdenum Chelate on the infestation and yield of soybeans. It was established that in the agrophytocenosis of soybean, a mixed type of infestation was formed, in which dicotyledonous young weeds predominated. Weed control efficiency was 75.5% 60 days after application of Frontier Optima. Spraying crops with the insurance herbicide Korum (1.5 l / ha + surfactant Metholate 1.0 l / ha) reduced the number of weeds in soybean crops by 89.5%. Consistent application of the soil herbicide Frontier Optima (1.0 l/ha) and the insurance herbicide Corum (1.5 l/ha + surfactant Metolate 1.0 l/ha) made it possible to destroy up to 98.9% of weeds compared to the control variant, where there was a natural background of clogging. The combination of the use of the above herbicides with the concentrated molybdenum microfertilizer Quantum-Chelate Molybdenum provided the best conditions for the growth and development of soybean plants. The amount of undesirable vegetation did not change in the areas where the microfertilizer was applied. But the air-dry mass of weeds was lower by 17.1-32.4%. The average soybean yield for three years of research on the variants where herbicides were applied compared to the control was significantly higher. When crops were sprayed with Frontier Optima herbicide (1.0 l/ha), it was 2.26 t/ha, and with Korum herbicide (1.5 l/ha + surfactant Metolate 1.0 l/ha) - 2.75 t/ha . With the sequential application of Frontier Optima (1.0 l/ha) and Corum (1.5 l/ha + surfactant Metolate 1.0 l/ha), the soybean yield was the highest and amounted to 2.94 t/ha.The highest content of proteins and oil was in the variant of sequential application of herbicides Frontier Optima (1.0 l/ha) and Corum (1.5 l/ha + surfactant Metolate 1.0 l/ha) - respectively 33.3% and 22.5 %. As a result of the treatment of crops on a herbicidal background with microfertilizer Quantum - Molybdenum Chelate, an increase in the weight of 1000 seeds by 2 g and the content of proteins and oil by 0.6% was noted.
