机械旱直播是我场水稻栽培的主要方法。它要求田面平实,种子播于地表,这些在一般沙壤土地上比较容易做到。而低洼粘壤土地,宜耕性差,种稻播前进行的耕耙作业,常形成满田坷垃,即使反复进行耙、耥、镇压,也难以消灭坷垃,从而造成大量种子钻缝,出苗稀少,严重影响了产量。这是我场旱直播栽培多年来没有解决的老大难问题。 1972年我场农二队、农三队在部分粘土地上试验了“秋耕不春耕”的整地方法,对消灭
Mechanical drought live broadcast is my field of rice cultivation the main method. It requires that the field be flat and the seeds be sown on the earth’s surface, which is easier to do on a sandy land. The low-lying clay loam is poorly tillage. Before harvesting, planting and raking operations often form full-bodied rubbings. Even if rakes, furrows and cracks are repeated, it is difficult to eliminate the rubbish, resulting in a large number of seeds drilled and sparsely populated. Seriously affected the yield. This is my longstanding problem that has not been solved for many years in the field. In 1972, our farm two teams and three farming teams tested the method of site preparation for “autumn plowing and spring plowing” on some clay soils,
