黄瓜属于雌雄异花同株,异花授粉作物,在花芽分化过程中,雌雄花的比例除受遗传因素支配外,还受环境条件影响。经过几年的试验摸索,笔者发现能够增加雌花数量,提高黄瓜产量的方法有以下几种: 一、适当降低夜间温度 黄瓜喜温暖,不耐寒冷,植株生育的界限温度为10-30℃,适宜温度为20-25℃,但不同生育时期对温度的要求不同。同时黄瓜雌雄花的比例和雌花的出现节位的
Cucumber belongs to the same strain of dioecious, cross-pollinated crops, flower bud differentiation process, the ratio of male and female flowers in addition to genetic factors, but also affected by environmental conditions. After several years of trial and error, I found that the number of female flowers can be increased to increase the yield of cucumber are the following: First, appropriate to reduce the night temperature Cucumber hi warm, intolerant cold, plant growth limit of 10-30 ℃, suitable The temperature is 20-25 ℃, but the different requirements of different temperature during birth. At the same time, the proportion of male and female cucumber flowers and the emergence of female flowers node
