我们公社土地瘠薄,常年大面积种植红薯,调茬困难,加上群众有用红薯浆水沤肥的习惯,土壤中根腐病菌多,红薯发病严重,1979年全社因病绝收面积占11.5%,直接影响粮食产量和群众生活的提高.为解决这一问题,除抓好推广抗病品种和调整茬口外,根据群众经验,1980年大力推广了红薯地施碳酸氢按的办法,具体施法:①红薯地整地时,每亩施入30斤左右作底肥。②育苗期拔苗两三茬后,随泼水每平方米苗床施一把碳按。
Our communal land is infertile, perennial large areas of planting sweet potatoes, stubble difficult, coupled with the masses of useful sweet potato water and fertilizer habits, root rot bacteria in the soil, sweet potato incidence is serious, the whole society in 1979 the total area due to the disease accounted for 11.5%, a direct impact on food In order to solve this problem, in addition to doing a good job in popularizing disease-resistant varieties and adjusting stubble crops, according to the masses’ experience, the method of applying bicarbonate on sweet potato land was popularized in 1980.
