摘要
水稻旱育秧营养土母剂各种营养元素及离子成份的组合,当床土1m^2含硫酸铵38.6g,氯化铵38.6g,过磷酸钙38.6g 硫酸钾11.7g,加少量的“敌克松”和“富士一号”等混合抑菌剂比较理想。如拔秧旱育苗时,每袋母剂(2.5公斤)加12.5公斤过筛早田土,经充分混拌均匀配制成营养土后撒施20m^2床面。近几年省内外(包括盐碱地)2.500多亩旱育苗床地施用结果看均取得省工简便,无菌壮苗效果显著,育苗效果优于同类产品,能增产增收,显著提高经济效益。
Nutritive soil‘mother form’which is used to raise rice seedling con- tains many kinds of nutrient elements and ions。There are sulphate of am- monia,ammonia chloride,calcium superphosphate and sulphate of patash by 38.6g,38.6g,38.6g and 11.7g per square metre separately,addihg a little fenaminosulf and isoprothiolane as bacteriostant。Each bag(2.5kg)of‘m- other form’mix with 12.5kg dry land soil of passing sieve uniformly,th- en broadcast distribution 20 square metre。Using the‘mother form’can s- ave labour,culture sound seedling and raise economic effect。
