杏花公社是水土流失严重,缺水,缺肥,土壤贫瘠的丘陵地区。全社21600亩稻田,绝大部分受到崩山、黄泥、淤沙的严重威协,历史上稻谷产量很低,1962年平均稻谷亩产仅为586斤。 1963年冬,土肥站在摸索改造低产田的同时,开始小量引种紫云英,面积395亩,由于认真执行了各项栽培技术措施,除极少数失败外,每亩鲜草产量一般2000斤左右。犁翻压青后,1964年早稻生势旺盛,试验田亩产达到497斤,比对照区犁冬田增产18％。试验结果引起
Apricot commune is a serious soil erosion, water shortages, lack of nutrients, soil fertility hilly areas. The whole community of 21,600 acres of paddy fields, most of the collapsing mountains, yellow mud, silt serious Wei Association, the history of rice production is very low, in 1962 an average of only 586 kg of rice per mu. In the winter of 1963, while trying to reform low-yielding fields, Soil Fertilizer started to introduce a small amount of asparagus with an area of 395 mu. As a result of serious implementation of various cultivation techniques and measures, with the exception of a very small number of failures, the output of fresh grass per mu was generally 2,000 kg about. After plowing and turning green, early spring rice had a strong potential in 1964. The yield per mu in the experimental field reached 497 kg, an 18% increase over the plowed winter field in the control plot. Test results
