1.深松耕法能减少机耕作业量,春秋两季都可进行,可以缓和秋季机、畜、人力的紧张状态、提高秋翻整地质量,做到翻耙压起垄等连续作业.同时也能防止因倒地早收造成减产、减收.2.深松后,土壤耕作层的土壤容重减轻,孔隙度增加,蓄水能力增强,为作物根系生长创造了良好条件.据测定,深松地上作物根扎得深、分布广,如玉米的鲜根重增加19%,根系分布范围扩大30%以上.
1. Deep plowing method can reduce the amount of tillage, spring and autumn can be carried out, you can ease the fall machine, livestock, manpower tension, improve the quality of the autumn flip, so flip rake pressure and other continuous operation Ridge. Can prevent the production loss due to the fall of the early harvest, reduced.2 After subsoiling, soil tillage layer of soil bulk density to reduce the porosity, increased water storage capacity for the root growth of crops to create a good condition.According to the determination of deep pine The ground crops are deeply rooted and widely distributed. For example, the fresh root weight of maize increased by 19% and the root distribution increased by more than 30%.
