油菜免耕撒直播栽培技术可以降低劳动强度,提高劳动工效。近年来,免耕撒直播油菜已作为永康市开发冬季农业,实现农业增产,农民增收的一个新举措。种粮大户金圣1997年冬种植的18.8亩免耕撒直播油菜,在生育期间遇长期阴雨寡照的气候条件下,仍实收菜籽1991.5公斤,平均亩产105.9公斤,高产攻关田亩产达150公斤,亩获利平均在120元左右,这充分显示了免耕撒直播油菜有较大的增产潜力。现将有关技术经验介绍如下:1.力争早播,施足基肥免耕撒直播油菜由于受前作茬口的制约,播种期一般都较迟,因此要尽量安排在早熟的晚稻田并及时收获晚稻,力争早播早出苗,争取10月底前播种完毕,最迟不超过11月10日, Rape no-tillage direct seeding cultivation techniques can reduce labor intensity and improve labor efficiency. In recent years, no-till broadcast rapeseed has been developed as Yongkang winter agriculture, to increase agricultural output, farmer income a new measure. Large-scale grain King Golden St. planted in the winter of 18.8 acres of no-tillage broadcast rape, in the long-term during the growing rainy weather conditions, still harvesting 1991.5 kg rapeseed, the average yield of 105.9 kilograms, yield of 150 acres of high yield field research Kg, profit average profit of 120 yuan or so, which shows that no-tillage rape direct seeding has a greater yield potential. The relevant technical experience is introduced as follows: 1. Strive for early broadcast, Shizujifei no-tillage rape broadcast rapeseed due to the constraints of the former crop, sowing time is generally late, so as far as possible to arrange early rice in the late rice harvest and late rice, Strive to early sowing early emergence, for the end of October sowing is completed, no later than November 10,
