随着农村种植业结构改革的进展,江南农村相当程度上普及了麦—瓜—稻耕作制。一般年份里,麦—瓜—稻每亩可以获得粮食超千斤,年产值四五百元(西瓜产量以2000斤计)的收益。为了进一步提高单位面积的经济效益,我们在麦—瓜—稻耕作制的基础上,改用麦田间作平菇(引进露地种植平菇的技术),然后套入西瓜—后茬稻的新型耕作制初步获得成功,经一年试种,亩产粮497斤,年产值高达1302.34元,纯收益比麦—瓜—稻高60～70％。
With the progress of rural planting structure reform, the rural areas in south of Yangtze River spread the wheat-melon-rice farming system to a certain extent. In general years, wheat - melons - rice per acre can be obtained over 1000 pounds of grain, four hundred or five hundred dollars annual output (watermelon production to 2000 pounds) income. In order to further improve the economic benefits per unit area, we switched from using wheat field to Mushroom cultivation (introducing planted mushrooms in the open field) based on the wheat-melon-rice farming system and then putting it into a new tillage system for watermelon-late rice Preliminary success, after a year of trial cultivation, yield 497 kg per mu, the annual output value as high as 1302.34 yuan, net income than wheat - melon - rice high 60 to 70%.
