花碱地种油菜,究竟是直播好还是移栽好?对这个问题,我们连续进行了两年试验,结果表明,直播油菜好于移栽的。1974年,我们在一块含盐0.15%,酸碱度(pH值)8.5左右的碱地上试验,直播的苗全、苗壮,平均株高106厘米,比移栽的高6厘米,主茎粗1.59厘米,比移栽的粗0.19厘米;收获时植株清秀老健、不倒伏,亩产菜籽246.8斤,比移栽的增产37.97%。1975年秋又种4亩碱地直播油菜,植株粗壮,荚多、荚大,籽粒饱满,平均亩产279斤。直播增产的主要原因是:
Cauliflower rape, live or transplanting is better? On this issue, we conducted two consecutive years of trials, the results show that live rape is better than transplanting. In 1974, we experimented on a piece of alkali with a salt content of about 0.15% and a pH value of about 8.5. The live seedlings were full and seedling with an average height of 106 cm and a height of 6 cm and a diameter of 1.59 cm , 0.19 cm thicker than the transplanted plants. When the plants were harvested, they were delicate and healthy, with no yield. 246.8 kg mu of rapeseed was produced, 37.97% more than that of transplanting. The autumn of 1975 and 4 acres of live rapeseed live, plant stout, pods, pods large, full grains, the average yield 279 pounds. The main reason for the live increase is:
