(一)一年来的农业生产大跃进,不断涌现的高额丰产“卫星”,充分证明,深耕是农业增产技术措施的中心.“水肥土种密”,中心是土,就是深耕,因为,第一,深耕可以加厚松土层,在深耕的同时实行分层施肥,特别是底肥、绿肥等有机肥料,促使深层的生土熟化,增加土壤中的团粒结构.每一个团粒,就是一个小水库,在深厚的土层中布满了这种无数的小水库,就大大增加了土壤含养水分和抗旱的能力.第二,土壤中的有
(1) The great leap in agricultural production in the past year and the continuous emergence of high-yielding “satellite” have fully proved that deep plowing is the center of technical measures for increasing agricultural output. "Soil and water are densely populated, First, deep plowing can thicken the soil layer, deep plowing at the same time the implementation of stratified fertilization, especially at the end of fertilizer, green manures and other organic fertilizers, to promote the deep maturation of raw soil, increase the soil in the pellet structure. Each pellet is a small reservoir , In the deep soil filled with countless small reservoirs, it greatly increased the ability of soil moisture and drought resistance .Second, the soil has
