南瓜是雌雄异花植物,必須借助昆虫的传粉才能授精結实。南瓜产量的高低,除了栽培技术以外,就是提高雌花的結实率。为了了解蜜蜂对南瓜授粉的增产效果,1963年6月,在同一品种、同一地区的南瓜地里,选择了生长势基本相同的植株,进行了授粉增产試驗。授粉的方式分为蜜蜂自由授粉、隔絕蜜蜂人工授粉、隔絕蜜蜂让螞蚁和其它昆虫自由授粉。試驗結果見下表: 从上表試驗結果可以看出,以蜜蜂授粉的效果最好。南瓜的果重、种子数、种子重量都
Pumpkin is a dioecious plant that must be inseminated and pollinated by insects. The level of pumpkin output, in addition to cultivation techniques, is to increase the rate of fruitfulness of female flowers. In order to understand the bee-pollinated pumpkin yield increase effect, in June 1963, in the same species, the same area of pumpkin land, choose the same growth potential plants, pollination yield test. Pollinating the way into the bees free pollination, isolated bees artificial pollination, isolated bees ants and other insects free pollination. The test results are shown in the following table: It can be seen from the test results of the above table that the effect of pollination with bees is the best. The weight of the pumpkin, the number of seeds, seed weight are
