杏保护地栽培中 ,由于棚室密闭无风 ,湿度大 ,缺乏传粉媒介 ,花粉生活力下降等原因导致坐果率降低 ,是目前存在的主要问题。杏的坐果涉及到树体营养、花芽形成的数量及质量、授粉受精、生理落果等多种因素 ,任何一个环节出现问题 ,将会严重影响坐果率 ,甚至造成“空棚”。因此 Apricot cultivated in the cultivation, as a result of greenhouse airtight without wind, humidity, lack of pollinators, pollen viability and other reasons lead to lower fruit set, is the main problem. Apricot fruit set involves the tree nutrition, quantity and quality of flower bud formation, pollination and fertilization, physiological drop fruit and other factors, any part of the problem, will seriously affect the rate of fruit set, or even result in “empty shed.” therefore
