摘要
比较研究了3种栽培法对水稻植株生长,光合速率,植株及籽粒全N,P,K含量,糙米全N,蛋白N含量,产量及构成因子的影响.结果表明,初拟栽培法最优,"三壮三高"栽培法次之,常规栽培法最低.与常规栽培法相比,初拟栽培法、"三壮三高"栽培法的糙米蛋白质含量,早稻分别增加了11.36,8.63g/kg,晚稻分别增加了8.33,6.19g/kg,早稻产量分别提高了19.14%,9.57%,晚稻产量分别提高了22.49%,13.53%.
This paper study the effects of three cultural methods on rice plant growth, pho tosynthetic rate, contents of total N,P,K in plant and grain, contents of tota l N and protein N in brown rice, and yield and its composition factors. The resu lts show that every index of preliminary recommend cultivation treatment is the highest, that of 'San-zhuang-san-gao' cultivation treatment are the second, and that of conventional cultivation treatment are the lowest. Compared with that o f conventional cultivation, the protein contents of preliminary recommend cultiv ation and 'San-zhuang-san-gao' cultivation in brown early rice increase 11.36,8.63 g/kg, that of late rice increase 8.33, 6.19 g/kg, and yield of early rice increase 19.14%, 9.57%, and that of late rice increase 22.49%,13.53%.
