为了尽快推广优良品种,我场大力进行小麦高倍繁殖,二营十七连科研班小麦一级种子田的高繁倍数平均在200倍以上,其中1亩春小麦中熟品种“辽春30”高繁试验田,亩播量0.8斤,亩产403斤,繁殖倍数为503.7倍。具体做法是:(一)整好土地。这块地是沙质黄壤土,肥力较高,前茬为大豆,深翻20厘米,秋耙。由于干旱,土块较多,整地质量不够理想,春季人工碎土一遍,耢地三遍,镇压一遍,达到了地平土碎的要求。(二)精选种子。所用种子经
In order to promote fine varieties as soon as possible, I vigorously field high multiplication of wheat, two camps and even seventeen even the first crop of wheat high multiples of more than 200 times the average, of which 1 acre spring wheat variety “Liao Chun 30” high Experimental field, mu sowing 0.8 kg, 403 kg per mu, breeding multiples of 503.7 times. The specific approach is: (a) the entire land. This piece of land is sandy loamy soil, high fertility, the former crop of soybeans, deep plowing 20 cm, autumn rake. Due to the drought, soil mass more, the quality of land preparation is not ideal, the spring artificial soil again, three times to suppress it again, reaching the requirements of the ground soil broken. (B) selection of seeds. Used seeds by
