1选择高产地块要选择地势平坦、土层深厚、土质疏松、能灌能排、保水保肥能力强的中上等肥力地块。2机械深翻(松),精细整地采取秋深翻(松),深度达到30cm以上,并且耙、压连续作业,做到秋季及时整地,打破犁底层,增加耕作层,提高土壤保水保肥能力。3增施有机肥有机肥是补充土壤有机质的重要来源,是土壤肥力的重要物质基础。结合深翻增施有机肥4.5万~7.5万/hm2。
1 Select high-yielding plots to choose flat, deep soil, loose soil, irrigation and drainage, water and fertility ability of the middle and upper fertility plots. (2) Mechanical deep plowing (loose), fine soil preparation Take autumn deep plowing (loose), the depth reaches more than 30cm, and rake, pressure continuous operation, so that timely and timely autumn planting, breaking plow the bottom, increasing tillage and improve soil water and fertilizer . 3 plus organic fertilizer Organic fertilizer is to supplement soil organic matter is an important source of soil fertility is an important material basis. Combined with deep plowing organic fertilizer application 45000 ~ 75000 / hm2.
