唐秦地区拥有水稻田近200万亩,历年均有不同程度的水稻缩苗现象发生,严重影响水稻产量的进一步提高,尤其是滦南县,唐海县(系柏各庄农场),近年来水稻缩苗较为严重,1987年滦南县胡各庄、柏各庄二乡水稻缩苗面积达10万余亩,唐海县八农场5.5万亩水稻有1万亩发生缩苗,为解决上述问题,我所早在1961年对水稻缩苗原因及防治措施进行调查研究。现已查明,水稻缩苗主要是土壤溶液总碱度 pH 值过高引
Tangqin area has nearly 2000000 acres of paddy fields, over the years have varying degrees of rice shrinkage phenomenon, seriously affecting the further improvement of rice yield, especially Luannan County, Tanghai County (Department of Parker Zhuang farm) in recent years, rice Shrinking more serious, Luannan County in 1987 Hu Gezhuang, Baigezhuang two rural rice shrinking area of more than 100,000 acres, 5.5 million mu of eight farms in Tanghai County, 10,000 acres of seedlings have shrunk, in order to solve the above problems As early as 1961, I investigated the reasons for the shrinkage of rice and the prevention and cure measures. It has been identified, rice seedlings soil alkalinity is mainly the pH value of high lead
