摘要
在丘陵红壤桃园中采用生物覆盖(有机物死覆盖和活覆盖)后,对夏秋期间的幼龄桃园不但具有降温保墒作用,还具有培肥改土效果,尤其是死覆盖对防止土温急剧升高、减缓土壤水分蒸发、补给土壤养分,加速黄桃幼树的营养生长及提高黄桃果实产量等方面具有明显的效果。活覆盖在降温保墒、培肥改土等方面虽不及死覆盖,但比不覆盖的对照仍具有明显的效果。因此,在丘陵红壤桃园行间种植豆科绿肥或与禾本科牧草混播,于适当时机将绿肥、牧草等有机物料割青浅埋,是新垦红壤桃园一项经济有效的土壤管理措施。
In young peach orchards of red soil in hilly area, application of mulch to the young yellow peach trees with straw or growing plants not only can conserve soil moisture and decrease soil temperature but also positively influence soil improvement in its fertility during summer and autumn, especially in the case of mulch with straw, which plays a great role in following processes: protecting from a dramatical raise of soil nutrients, accelerating thd vegetative growth in young trees of yellow peach and increasing fruit yield.The effects of mulch with growing plants on the orchard soil are less than those with straw, but the effects of the former are still obvious as compared with control of non-mulch.Therefore, it is an economical and useful measures for soil management in peach orchards of the newly reclaimed red soils in the hilly area that leguminous green manure crops and/or foliage grass are grown in the interrow of the peach trees and they are turned shallowly over in the soil in a proper period.
