摘  要:
通过油菜(Brassica napus L.)绿肥还田试验,研究机插对一季中稻两优1318植株生物量及产量性状的影响.结果表明,油菜绿肥还田有利于提高机插一季中稻的有效穗数和单产,有效穗数比对照增加7.0%,实际产量比对照增产4.2%,且有助于提高水稻抗倒性.这可能与油菜绿肥增加土壤的有机质含量和P、K含量有关.

摘  要:
Experiment was conducted to study the effect of rapeseed as green manure on biomass and yield of mechanically transplanted middle-season rice variety Liangyou 1318. The results indicated that rape green manure was beneficial to the increase of effective panicle number and yield of mechanically transplanted middle-season rice. After using rapeseed as green manure, the effective panicle number and yield of rice increased 7.0% and 4.2%, respectively, while compared with the control treatment. It could also improve the lodging resistance of rice. This may be related to the increase of soil organic matter,P and K content by rape green manure application.
