不同土壤水分调控对夏黑葡萄生长的影响

Influence of Different Soil Water Regulation on Growth of ′Summer Black′ Grape

为了解不同灌水量对夏黑葡萄生长的影响,在不同栽培模式下,分别设置4个水分调控处理,观测各处理生长期内葡萄的生长指标:新梢长度、新梢节间长度、新梢粗度、百叶鲜重、叶面积等。结果表明:不同水分处理对成龄葡萄生长具有显著影响。葡萄新梢长度、新梢粗度和叶面积的生长变化在不同栽培模式下随着灌水量增加而增加,且露地栽培下生长量比避雨栽培下生长量大。在露地栽培下,夏黑生长量为灌3次水处理>灌2次水处理>灌1次水处理>不灌水处理。在避雨栽培下,灌3次水加覆膜能满足葡萄生长的需要。

In order to understand the influences of different soil water regulation on ＇Summer Black＇ grape growth,the test was conducted to 4 water regulation treatment in different cultivation modes. The growth indicators of grape in the growth stage （new slightly length, new slightly internodes length, new slightly diameter,leaf fresh weight,leaf area, etc. ） were observed. The results showed that water regulation had a significant influent on mature gape growth.The growth changes of grape new slightly length, new slightly diameter and leaf area were increased with the increasing of irrigation amount in different cultivation modes ,the growth in outdoor was larger than that under rain shelter cultivation.The growth of ＇Summer Black＇ grape under open field cultivation was that：with 3 times water treatment〉with 2 times water treatment〉with 1 times water treatment〉without water treatment. The treatment in 3 times water and film mulching, could meet the needs of grape growth under rain shelter cultivation.
