早春及冬季保护地黄瓜常出现化瓜现象,即雌花开放后,花蒂黄化萎缩,子房不再生长膨大。化瓜影响早熟性,使早期产量及总产量受损失,直接影响经济效益,成为黄瓜生产上的一大难题。黄瓜化瓜的原因是多方面的:如温度过低,水份不足,养分比例失调等不良条件都会阻碍黄瓜果实的正常生长发育,引起化瓜。而单性结实能力无疑也是黄瓜的一个重要因素。本文试就此进行探讨。材料和方法供试黄瓜品种:津杂2号。处理方法:施用各种植物生长刺激素、稀土元素及人工授粉。药液采用小喷雾器喷
In early spring and winter protected cucumber often melon phenomenon, that is, female flowers open, flower pedicel atrophy, ovarian growth no longer dilated. Melon affects premature, so that the early yield and total yield loss, a direct impact on economic efficiency, become cucumber production a major problem. Cucumber melon for many reasons: such as the temperature is too low, inadequate water, nutrient imbalances and other adverse conditions will hinder the normal growth and development of cucumber fruit, causing melon. The uniparent ability is undoubtedly cucumber is an important factor. This article discusses this discussion. Materials and methods for testing cucumber varieties: Tsz miscellaneous 2.
