我省江淮丘陵地区是一个小麦低产区,一般亩产七、八十斤,最低的只有二、三十斤。由于小麦单产低,一方面飼料、飼草少,肥料缺乏,常年不施肥,或只施用少量質量很差的土杂粪,土壤肥力逐年下降,另一方面,不得不扩大粮食作物的播种面积,旱地山芋、小麦两熟,水田稻、麦两熟的比例很大。怎样扭轉这种只用不养的局面呢?关键在于探索簡单易行、經济有效的办法,迅速提高小麦的单产,为扩种綠肥、改变輪作制度和提高地力创造条件。为了解决这一問題,我們在合肥市园林公社,研究了当地小 Jianghuai hilly areas in our province is a low-yield wheat area, the general mu produce seven or eight pounds, the lowest only two or three pounds. Due to the low yield of wheat, on the one hand, lack of feed, forage and lack of fertilizers, perennial fertilization, or the application of only a small amount of poor quality soil and manure, soil fertility decreased year by year, on the other hand, had to expand the sown area of ​​food crops, Dry land potato, two wheat, paddy rice, wheat, a large proportion of two cooked. The key is to explore simple and cost-effective ways to rapidly increase the yield of wheat and create the conditions for expanding green manures, changing the rotation system and improving manpower. In order to solve this problem, we studied the local small in Hefei Garden Commune
