为了促使所栽培的果菜类本身能适应温室环境条件,我们在1954年冬就用水黄瓜开始播种,选择其比较能适应冬季条件的品种作为亲本,1955年春在温室内得到杂交的黄瓜种子,到1955年冬进行第二代的试验对比,由于在温室环境条件下杂交所获得的种子,在1955年冬季温室栽培吋表现得比较好,黄瓜生长都 In order to make the cultivated fruits and vegetables adapt to the environmental conditions of the greenhouse, we began to sow the cucumber with water in the winter of 1954. We chose the varieties that were more suitable for the winter conditions as the parents and got the hybrid cucumber seeds in the greenhouse in the spring of 1955. By 1955, Compared with the second generation in winter, the seeds obtained during the hybridization under greenhouse conditions performed better in winter in 1955 than in greenhouse.
