乙烯利用可抑制桃树新梢生长、导致落果,延迟翌年开花物候期。在使用中,浓度很系键,高浓度常引起落叶、流胶、殭芽和枝条枯死。本试验表明,安全使用浓度为500ppm以下,疏果时浓度不应高于250ppm。
Ethylene use can inhibit the growth of peach shoots, leading to fruit drop, delayed flowering phenophase the following year. In use, the concentration of keys, often caused by high concentrations of leaves, plastic flow, stiff buds and branches dead. This test shows that the safe use of concentration of 500ppm or less, when the concentration should not be higher than 250ppm.
