1980年笔者同宜春市黄颇大队蔬菜科研组从外省引进杂交大白菜,作品种对比试验,1981—1983年继续进行大白菜高产栽培,在劳力、肥料不足的情况下,连续三年亩产均稳定在万斤以上。现将稳产经验总结如下:一、选择抗病高产品种 1980年,从青岛市农科所、中国菜科所、杭州市四季青公社常青大队等单位引进六个杂交大白菜品种,进行了栽培对比试验。于8月18日播种,11月首先采收青杂早丰,以后,陆续采收其它品种,各品种表现各有其优缺点。青岛的青杂早丰虽然略早熟,但抗软腐病差,产量低,生产价值不大。青杂4号表现株型紧凑,生长势强,结球最快,但抗病力一般,产量也不高。杭州的城青2号,各方面形态近似青杂3号,包心略早,但抗病较差,产量也
In 1980, with the Yellow Riding Group of Yichun City Brigade vegetable research group from other provinces to introduce hybrid Chinese cabbage, varieties of contrast test, 1981-1983 continue to carry out high-yielding Chinese cabbage, labor, lack of fertilizers, the average yield per mu for three years Stability in more than kilos. Now stable production experience is summarized as follows: First, the selection of high-yielding disease-resistant varieties In 1980, from Qingdao Agricultural Science Institute, Chinese food science institute, Evergreen Brigade of Hangzhou Sijiqing commune and other units to introduce six hybrid Chinese cabbage cultivated Comparative Test. Seeds were sown on August 18, and Zanshou-Zhaofeng was first harvested in November. Afterwards, other varieties have been harvested one after another, and each variety has its own advantages and disadvantages. Green Zaifeng Qingdao, although slightly precocious, but poor soft rot resistance, low yield, production value is not large. Green hybrid performance on the 4th plant compact, strong growth potential, the fastest ball, but disease resistance in general, the yield is not high. Hangzhou City Green 2, in all aspects similar to green hybrid No. 3, wrapped around slightly earlier, but less resistant to disease, the yield is also
