摘要
通过高垄平台耕作法与垄作对照土壤温度的对比调查 ,结果表明 ,高垄平台可明显提高白天温度 ,14 :0 0高台提高 5 % ,常规台提高 2 .8% ;7:30高台提高 4 .96 % ,常规台提高 3% ;降低夜间温度 ,高台为垄作的 98% ,常规台为垄作 99% .这样可以加大昼夜温差 。
The temperature of high-ridge and platform compared with ridge farming is investgated. The result shows high-ridge and platform can clearly increase the temperature in days and drop the temperature at night. High ridge and platform increases 5% and normal platform increases 2.8% at 14:00;and at 7∶30, 4.96% and 2.8% respectively At night,the soil temperature of high ridge and platform is 98% and normal platform is 99% of the ridge farming This is advantage to increase of soybean yield.
