粮棉轮作模式下深翻对冬小麦灌浆期旗叶衰老、灌浆特性和产量的影响
Effect of Deep Plowing on Senescence and Grain Filling Characteristic and Yield of Winter Wheat of Cotton-Wheat-Maize Rotation System
摘要
Abstract
In order to explore the effects of deep plowing on grain filling of winter wheat,four treatments inclu-ding rotary tillage(CK)and three tillage depths(30,50,70 cm)were used in field experiment.Our results showed that deep plowing increased the SPAD of flag leaf and delayed the senescence of wheat;soil water content,photosyn-thetic physiological and grain weight were also improved.Further studies revealed that deep plowing up regulated Rmaxand Rmean,,Wmaxappeared later.The results suggested that deep plowing increased the yield of winter by in-creasing grain weight and harvest index.The results suggested that P30 and P50 treatments increased the yield of winter by increasing grain weight and harvest index.The soil water content of P50 was higher than P30.The most ef-fective way to increase the yield of winter in agricultural production is deep plowing.关键词
