摘要
1985—1988,在临沐县丘陵坡地果因对苹果、梨、桃、李、杏园进行以麦秸、麦糠每年每亩1000kg连续上覆以不翻入土壤的覆盖与清耕对照处理对比试验,结果表明,覆草有培肥土壤,改良土壤结构;蓄水保墒,保持水土;调节果园地温和气温,提高果树的光合效率,抑制杂草、虫害;促进果树生长发育,优质增产等效应。在我国果树多分布在旱薄地的情况下,果园覆草具有实际意义。关于覆草造成鼠害及某些害虫防治困难的问题,应进一步研究解决。
The control experiments of apple,pear,peach,plum and apricot treeorchards covered with wheat straws and glumes of 1000 kg per mu in succe-ssions without turning into soils as against clean plowing were conducted inhilly sloping lands in the years 1985-1988.The results indicated that strawmultching has such good effects as dettering soil fertility,improving soil stru-cture,storing water and preserviug moisture,conserving soil and water,regulating soil and atmosphere temperatures,improving photosynthetic efficiencyof fruit trees,inhibiting weed growth and pest and disease spreading,promotingfruit tree growth and development and producing high-yielding and fine qualityfruits In case of fruit trees distriduting in the poor and rainfed lands,in China,orchards covered with straws is of greatly practieal significance.Therefore,it is worth further studying and solving the difficult problems that rats andinsect pests damade is caused by multching.
