近年来,我场在“稻、豆”一年两熟的基础上,适当地试行“稻、豆、油”,即早稻—秋大豆—油菜一年三熟的栽培制度,获得良好效果。1978年试验示范面积3.85亩,早稻栽二九矮1号(原种)亩产735斤,秋大豆种矮脚青(原种)亩产417.5斤,油菜栽秀油2号(原种),目前长势良好。实践证明,在水源不充足,不能栽二季晚稻以及栽后遇旱不保收的地区,扩大秋大豆种植面积,实行水旱轮作,是用地和养地相结合,改良土壤,减少稻田杂草和病虫害,达到增产增收的一条具有广阔前景的新途径。
In recent years, based on the two crops of “paddy and beans” a year, our field tried out the cultivation system of “paddy, bean and oil”, namely, the early rice - autumn soybean - rape three crops a year and achieved good results. In 1978, the experimental demonstration area was 3.85 mu, and 735 kg per mu for early maturing rice on January 29 (original), 417.5 kg per mu for autumn soybean varieties (original) per mu, Currently growing well. Practice has proved that in the water is not sufficient, can not planted two seasons of late rice and planted in the event of drought do not receive income areas, expanding the planting area of autumn soybean, the implementation of the rotation of water and land, is the combination of land and raising land, soil improvement and reduce paddy weeds and Pests and diseases, to achieve a new prospect of broad prospects for increasing production.
