GROWING METHOD OF MIDDLE-LATE VARIETIES OF SOY TO BE USED AS GRAIN, IN THERMAL MODE OF 2401-2600C, MAINLY IN DRIP IRRIGATION SYSTEM

摘要

FIELD: agricultural industry.;SUBSTANCE: method includes stubble cleaning of the preceding crop, soil treatment with herbicide, application of fertilisers, and real tillage. Besides early-spring soil mellowing and smoothing, pre-sowing irrigation, and cultivation 4-5 cm deep is performed. After that sowing, soil packing prior to and after sowing, harrowing of emerging crops, irrigation during vegetation period, plant desiccation, and harvesting is performed. Together with irrigation water, during main vegetation periods there applied are microelements. During budding phase there applied are the following microelements: molybdenum, boron, cobalt, and manganese in quantity of 160-220, 80-180, 40-90, and 800-1200 g/ha respectively. The following microelements are applied during blooming phase: molybdenum in quantity of 300-450 g/ha, boron - 120-270 g/ha, cobalt - 30-80 g/ha, manganese - 280-470 g/ha, and cuprum - 120-270 g/ha. During bean formation phase there applied, together with irrigation water, is molybdenum in quantity of 120-200 g/ha, boron - 60-100 g/ha, cobalt - 70-180 g/ha, cuprum -160-230 g/ha, and zinc - 70-180 g/ha. During grain formation there applied is as follows: molybdenum - 20-60 g/ha, boron - 40-90 g/ha, cobalt - 35-105 g/ha, manganese - 150-190 g/ha, zinc - 200-300 g/ha, cuprum - 60-80 g/ha, and sulphur - 17-24 kg/ha.;EFFECT: improving soy grain harvesting capacity, and protein and fat content.;6 tbl
