沙地果树园地表覆盖栽培试验

Experiment on Mulching Cultural Technique of Sandy Land Orchard

1987—1989年,我们在山东禹城县新垦沙荒地开发利用中,为改善果树立地条件,对葡萄、山楂、桃、李等果树园地表,进行秸秆覆盖大区对比试验。结果表明,覆盖能调节土温,夏季避免果树高温灼伤,冬季能够安全越冬。并改善沙土水分、养分等理化性状,抑制杂草生长,减轻风沙流危害。使果树生长发育良好,产量提高。

In order to improve the site conditions of fruit trees such as gree, hawthorn, peach, pear etc. a comparative experiment on wheat straw mulching sand surface was conducted on newly-created sand land in Yucheng County,Shandong Province in 1987-1989. The results showed that mulching treatments could adjust soil temperature,avoid high-temperature harms to fruit trees in Summer and ensure their safe overwintering in winter, improve water and nutrient conditions, suppress weed growth and lessen sand drift damages,thus better the growth and development of fruit trees and increase yield.
