不同密度条件下油后直播棉冠层温度对生长发育的影响
The effect of canopy temperature on growth and development of directly seeded cotton after rape under different density
采用随机区组试验设计，共设置6个密度处理：15000株·hm-2、37500株·hm-2、60 000 株·hm-2、82500株·hm-2、105000株·hm-2和127500株·hm-2,全天监测棉花倒四叶温度及冠层温度，定期测定棉花各器官干物质质量、籽棉产量等农艺性状，探索不同密度条件下油后直播棉冠层温度对生长发育的影响。结果表明：赣早5号冠层温度随密度的升高而升高；与2021年相比，2022年高温干旱条件下赣早5号整体营养生长更加旺盛，…查看全部>>
A randomized block design of experiments was used to set up six density treatments: 15 000 plants·hm-2,37 500 plants·hm-2, 60 000 plants·hm-2,82 500 plants·hm-2,105 000 plants·hm-2 and 127 500 plants·hm-2.The temperature of the top fourth leaves and canopy of cotton were monitored throughout the day, and the dry matter of cotton organs, seed cotton yield and other agronomic traits were measured regularly to explore the influence of canopy temperature on the …查看全部>>
