摘要
花生采用覆膜及不同株行距处理,结果表明覆膜能够增加地温,在前期保持土壤水分,提高出苗率,促进提早成熟。覆膜栽培方式与单行不覆膜栽培方式相比,在分枝数、荚果数,百果重、出仁率、单株生产力等主要经济性状都有明显提高,增加光合面积,提高光合效率,增产率分别为96.9%和96.2%,增产达极显著水平。
The experiment showed that peanut film mulching could increase soil temperature, preserve soil moisture, increase plough layer soil water, improve the environment for peanut growth and finally is in favor of the yield. Compared with common way of culture, peanut film mulching could increase yield over 96%.
