不同种植模式对新压砂瓜田土壤养分和土壤酶活性的影响
Effects of different cropping patterns on contents of soil nutrients and soil enzyme activity of the new gravel-sand mulching field watermelon
摘要
Abstract
Under the field conditions ,we studied the contents of soil nutrients and soil enzyme activities at different growth stage of the new gravel-sand mulched field watermelon ,with three treatments of monoculture (T1) ,intercropping (T2) ,and monoculture with plastic film mulching (T3) .The results showed that the contents of soil nutrients in this three cropping patterns of T3 were highest ,followed by T2 and T1 for the whole growth period of watermelon .Soil organic matter showed a bimodal pattern of high - low - high - low ,and the same for other soil nutrients .Soil enzyme activities were highest for T3 ,medium for T2 ,and lowest for T1 .Significantly positive correlation between soil enzyme activities and soil nutrients was detected .Watermelon yield followed the order of T3>T2>T1 .Results obtained are helpful for wa-termelon production through gravel-sand mulching .关键词
