我省目前大豆高产栽培走的是密植苗足的道路,而笔者却应用地膜覆盖,走稀少覆的道路,突破高产新纪录。经几年试验,亩产都超过250公斤,高者达300公斤。今后,随着地膜覆盖与分枝性强、单株产量高的品种相结合,单产将会有更大的突破。所谓稀少覆栽培法,即稀植(每公顷保苗10~12万株)、少耕(减少第一、二遍中耕)、覆膜栽培法,现总结如下: 一、稀少覆栽培方法
At present, high-yielding cultivation of soybean in our province takes the road of dense planting and seedling cultivation. However, the author applies mulching and taking the path of scarce cover and breaking new record of high yield. After several years of tests, each of them produced more than 250 kg of mu and the highest of 300 kg. In the future, with the coverage of mulching film and branches with high yield, the combination of high yield varieties, yields will have a greater breakthrough. The so-called rare cover cultivation method, that is, thin planting (per hectare seedling seedlings 10 to 120,000), less tillage (to reduce the first and second time cultivator), film cultivation method, are summarized as follows:
