近几年保护地春黄瓜栽培面积不断扩大,成为保护地早熟栽培的重要内容之一。据1991年统计,杭州市郊保护地春黄瓜面积达3600亩,约占夏菜总面积的28%。早春保护地小气候的特点是光照弱、光照时间短、低温高湿。不利于黄瓜结瓜,植株易发病。因此要求保护地黄瓜品种较耐低温和较耐弱光,抗病性强,单性结实力好,从而达到早熟丰产。杭州市春黄瓜主栽品种“杭青1号”和“杭青2号”,在保
In recent years, the area of cucumber cultivation has been continuously expanding and has become one of the important contents of precocious cultivation in protected areas. According to statistics in 1991, the area of spring cucumber in the suburbs of Hangzhou reached 3600 mu, accounting for about 28% of the total area of summer vegetables. The characteristics of the microclimate in early spring protection are weak light, short light time and low temperature and high humidity. Not conducive to cucumber cucumber, plant prone disease. Therefore, the protection of cucumber varieties are more tolerant to low temperature and more resistant to weak light, strong disease resistance, good unisex, so as to achieve early maturity. Hangzhou cucumber cultivars “Hangqing 1” and “Hangqing 2”, Paul
