摘要
以2个甜瓜品种为试材,研究了不同栽培管理方式和杂交授粉方法对甜瓜杂交种产量的影响。结果表明:露地栽培和设施栽培均以单蔓双果的整枝方式为最佳;设施栽培条件下,秋季制种的种子产量明显高于春季;春季的杂交授粉时期以5月中下旬为宜;蕾期授粉有利于提高坐果率和种子产量,可广泛采用;坐果灵能显著提高坐果率,但对种子的生长发育有不良影响。
Two melon varieties were used as test materials and the effects of cultural means and cross-pollination methods on their hybrid seed yield were studied. The results showed that the best pruning method was two fruits per vine in both protected culture and open culture. In protected culture the seed yield in autumn was significantly higher than that in spring. The appropriate cross - pollination period in spring was mid to late May. Bud pollination could improve the fruit set percentage and seed yield and could be widely adopted. ＂KT-30＂ treatment could effectively increase the fruit set percentage but had a bad effect on the seed growth and development.
