我場青山大队六中队,1963年在一块面积八亩,栽培技术及耕作管理相同的小粉土稻田(即粉砂粘壤质田)里,一边(三亩)系边耙边栽的浑水田,另一边(五亩)系耙后二天栽的清水田,品种大叶早,对比試驗表明:渾水栽的秧苗二至三天內发出新根,亩产五百六十七斤;清水栽的秧則五至七天才发新根,亩产五百四十斤。1964年推广全場后,也获得了显著的增产效益。近年釆的实践証明,渾水栽秧对缺乏有机質(一般含量0.7—1.0%)和无机胶粒(粘粒含量
My field Qingshan Brigade Six Squadron, in 1963 in an area of 8 acres, cultivation techniques and tillage management of the same small silt paddy fields (ie silty clay field), one side On the other side (five mu) is the paddy fields planted two days after raking. The varieties of big leaves are early, and the comparative tests show that the muddy hydroponic seedlings send out new roots within two to three days, yielding 567 kilograms per mu; Five to seven days seedlings then send a new root, yield 550 pounds. After the promotion of the audience in 1964, it also obtained significant yield increase. Practice in recent years preclude the muddy water planted on the lack of organic matter (the general content of 0.7-1.0%) and inorganic particles (clay content
