春季防虫网温湿度变化对砂糖橘春梢生长的影响

Effect of the Change of Temperature and Humidity in Spring Insect-Proof Net on the Growth of Spring Tip of Citrus reticulata cv.Shatangju

探讨了防虫网覆盖栽培技术对网室温湿度和砂糖橘(Citrus reticulata Blanco cv.Shatangju)春梢生长的影响。结果显示,40目透光防虫网对1-4月份(春季)砂糖橘春梢的生长具有促进作用;同时比较了防虫网内外温湿度变化对粉虱类、红蜘蛛类、潜叶蛾类数量的影响,认为防虫网对砂糖橘春梢生长的促进作用可能是通过对柑橘害虫和网室温湿度的调控这两个方面来实现的。

This experiment is mainly used to study the effect of insect-proof net mulching cultivation technology of the temperature and humidity of the greenhouse and the spring tip growth of Citrus reticulata Blanco cv.Shatangju.This study shows that 40-mesh translucent insect-proof net has a positive effect on the spring tip growth of C.reticulata cv.Shatangju in the spring from January to April.In the meantime,according to the change of the temperature and humidity inside and outside of insect-proof net and the change of quantity of aleyrodidae,red spiders and phyllocnisidae,we think that the enhancement of insect-proof net on the spring tip growth of C.reticulata cv.Shatangju is possibly achieved by two aspects of the regulation of citrus pests and the temperature and humidity of network room.
