葡萄避雨棚内外光照强度及温度变化动态研究

Grape Rain Shed Light on the Dynamic Changes of Internal and External Strength and Temperature

本文以葡萄品种“京秀”避雨棚栽培为研究对象,调查了不同的天气条件下,小避雨棚内外温度及光照强度的变化及差异.结果表明,在不同的天气下,小避雨棚下的温度变化和露地温度变化是不同的,晴天6-10时和19-21时棚下温度略高于露地温度,10-19时棚内温度略低于露地温度;多云天气时,棚下温度全天略低于露地温度;阴天时,棚内外温度变化基本一致.小避雨棚下的光照变化与外界光照变化一致,晴天或多云天,当外界光照强度较高时,避雨棚可以有效的降低光照强度.避雨棚对葡萄生长所需温度、光照影响不大,对病害预防可以起到很好的防控作用.可见,避雨栽培是葡萄能够在多雨地区进行成功种植的有效方法.

Taking grape variety of ＇Jingxiu＇ as material, the variation of temperature and light intensity in internal andexternal rain-shelter was tested under different weather condition. The result showed that the temperature of rain-shelterwas different from that of field. The temperature of time from 6-10 and 19-21 under rain-shelter was higher that thetemperature of the field condition while 10-19 was lower than the field on sunshine time. On the cloudy condition thetemperature of rain-shelter was lower than the field the whole day. The change tendency of light intensity under rain-shelter was similar with the outside. On sunny or cloudy days, When the external light intensity is higher, Rain shelter caneffectively reduce the intensity of light. There are little effect to the grape growth on temperature and light intensity underrain-shelter. The rain-shelter can have the benefit of control disease and insect pests. That indicated the rain-shelter wasan effective method to rainy region.
