在葡萄园进行连续三年的试验,设清耕、覆膜、割压、割覆、自传种五个处理。结果表明,绿肥处理与清耕、覆膜处理相比:(1)夏季高温期,表土可降温8℃,20cm深处土温降低1—2℃。0—20cm层含水量平均提高0.7%～1.1%。(2)叶片叶绿素含量和光合作用强度有明显提高。叶片N、P、K三要素含量也有提高趋势,其中以割压处理效果最佳。(3)平均增产7.1%～12.3%,果实含糖量提高0.3%～1.3%。综合效果和效益,以割压和自传种两处理最佳。
In the vineyard for three consecutive years of trial, set up clearing, laminating, cutting, covering, self-transmission of five kinds of treatment. The results showed that compared with tillage and film mulching treatment, (1) During summer high temperature period, topsoil could be cooled down to 8 ℃ and soil temperature decreased to 1-2 ℃ at depth of 20cm. The water content in the 0-20cm layer increased 0.7% ~ 1.1% on average. (2) Leaf chlorophyll content and photosynthesis intensity has been significantly improved. Leaf N, P, K elements also increased the trend, of which the best effect of cutting pressure. (3) 7.1% ~ 12.3% increase in average yield and 0.3% ~ 1.3% increase in sugar content in fruit. Comprehensive effects and benefits to cutting pressure and self-transmission of the two best.
