对当前棉田流行立体种植模式的探讨

APPROACH TO STEREOSCOPI C CULTIVATING MODELS IN COTTON FIELD TODAY

本文评论了几种新近在棉田发展起来的立体种植模式及其优、缺点,所论及的新模式为“小麦(或大麦)—西瓜(或甜瓜)—棉花”、“小麦(或大麦)—蔬菜—棉花”、“小麦(或大麦)—玉米—西瓜(或甜瓜)—棉花”、小麦(或大麦)—甘薯—棉花”、“小麦(或大麦)—棉花—食用菌”或“小麦(或大麦)—豆类—棉花”等,而以传统模式“小麦(或大麦)棉花”为对照。结论认为,有些新模式不仅能增产、增值,而且还能改善棉田生态条件,并不使棉花明显减产。

It was reviewed that several newly developed models of stereoscopic cultivating in cotton field and their merits and demerits in this paper.The newly developed models concerned here were the models of wheat(or barley)— watermelon(or mellon)—cotton,wheat(or barley)—vegetables—cotton, wheat(or barley)—watermelon(or melon)—cotton—corn,wheat(or barloy)—sweet potato—cotton,wheat(or barley)—cotton—edible fungi,and Wheat(or barley)—pulse—cotton,etc.checked by traditional model—wheat (or barley)—cotton.It was recognized that some new models could not only increase yields and output values,but also improve ecological conditions of cotton field without cotton yield decreased apparently in conclusion.
