曲靖县越州公社越州大队,田多地少,旱地多分布在老冲积台地上,土质为瘦红壤,具有“干、酸、瘦、薄、缺磷”的特点。土壤有机质含量低,一般在百分之一左右,不保水,不保肥。包谷生长形成“天干苗不长,天雨苗发黄”的状况,产量低而不稳,一般亩产三、四百斤左右。为了提高土壤肥力,增加粮食产量,我们对旱地绿肥如何就地利用的问题,进行了试验研究。

The Yuezhou brigade of the Yuezhou commune in Qujing County has less fields and less land. The dry land is mostly distributed in the old alluvial platform and the soil is thin red soil with the characteristics of “dry, sour, thin, thin and lack of phosphorus”. Soil organic matter content is low, generally about one percent, not water, not fertilizer. The formation of the Valley Valley, “dry days do not grow long, rainy days”, the output is low and unstable, the general average per mu three or four pounds. In order to improve soil fertility and increase food production, we conducted a pilot study on how to use green manures on-site in drylands.
