1.抓紧垄沟深松。要抓住天气晴好的有利时机,立即进行深度为20~25厘米的垄沟深松,放寒增温、消灭杂草,促进幼苗快速生长发育。2.加强中耕培土。要坚持早铲、早趟,全生育期力争做到三铲三趟。第一遍在大豆出苗后到第一片复叶展开前进行,以后每隔10~12天铲趟一次,中耕深度应随根系生长状况由深到浅再浅的方式进行,疏松土壤,透气增温,促进土壤微生物活动,增强土壤的抗旱防涝能力和植株的抗倒伏能力。
1. Seize the ditch deep loose. To seize the favorable weather, fine opportunity, immediately depth of 20 to 25 cm deep furrows, cold warming, eliminate weeds, and promote rapid growth and development of seedlings. 2. Strengthen cultivating soil. To insist on early shovel, morning trip, the whole growth period strive to achieve three shovel three times. The first pass after the emergence of soybean to the first compound leaves before the unfolding, after every 10 to 12 days shovel times, depth of cultivation should be with the growth of the root system from deep to shallow and shallow way, loose soil, breathable increase Temperature, promote soil microbial activities, enhance soil drought resistance and waterlogging capacity and plant lodging resistance.
