在十年前研究水稻不整地直播技术的过程中,遇到施肥困难、氮素肥料流失和由于栽培失当引起的前期旺长、秋季衰败(“秋落”)等问题。此后,从防止秋落,减少肥料流失,使少量肥料能维持较长时期肥效的目标出发,吸取了青森县深层施肥的经验,先后试验了固体肥料和液态氮肥的深层施肥,并研究在育苗插秧的条件下与深层施肥相应的前期控制及水
In the course of studying the technology of direct broadcasting of rice irregularly 10 years ago, it encountered such problems as fertilization difficulty, loss of nitrogenous fertilizers, pre-boom due to improper cultivation and declining fall (Qiu Fall). Since then, from the prevention of fall, reduce fertilizer loss, so that a small amount of fertilizer can maintain a longer period of time efficiency of the goal, draw Aomori experience of deep fertilization, has tested the solid fertilizer and liquid nitrogen fertilization, and to study seedling transplanting Under the conditions and the corresponding deep application of pre-control and water
