稻田红花、油菜混播,为什么油菜生长健壮,抗寒抗病?无意撒落在田头路旁的“野生”油菜,为什么发棵很旺,结荚又多?油菜能否直接撒播栽培呢?为了探讨这个问题,我所从1978年开始,连续四年进行了油菜免耕直播和翻耕直播试验,均取得了满意的结果。稻板田油菜撒直播,1979年春收油菜试验面积0.18亩,折合亩产283斤,1980年试验面积2亩,亩产合141斤;旱地翻耕油菜撒直播,1981年春收油菜试验面积1.5亩,折合亩产128斤,1982年春收油菜面积
Why is rape growing robust, cold and disease? No intention to sprinkle the “wild” rape next to Tin Tau Road, why the plants are very prosperous, pods and more? Rape can be directly broadcast sowing it? In order to explore this issue, we started from 1978, four consecutive rape no-tillage and tillage direct seeding test, have achieved satisfactory results. Paddy field rape sow broadcast, spring 1979 harvest rapeseed area of 0.18 mu, equivalent to 283 kg per mu, 1980 test area of 2 mu, mu yield 141 pounds; dry land rape sowing broadcast live in 1981 Spring rape harvest test area of 1.5 acres , Equivalent to 128 pounds per mu, collected in spring 1982 rapeseed area
