摘要:

以天津市4个水稻主栽品种为供试材料,采用机插秧和旱直播两种模式进行种植,比较了两种栽培模式水稻的产量、产量构成因子以及经济效益。结果表明,旱直播条件下的水稻株高显著低于机插秧,两种模式下水稻单位面积有效穗数、穂长、千粒重、每穗粒数、结实率和实际产量因品种而异。从经济效益来看,旱直播高于机插秧。

关键词: 水稻, 机插秧, 旱直播, 产量, 产量构成因子

Abstract:

Four main rice varieties in Tianjin were used as test materials, and two models of machine-transplanted seedling and dry direct seeding were used for planting, the yield, yield component factors and economic benefits of the two cultivation models were compared. The results showed that the plant height of dry direct seeded rice was significantly lower than that of machine-transplanted seedling rice, the effective panicle number per unit area, panicle length, 1 000 grain weight, number of grains per panicle, seed setting rate and actual yield varied with varieties. In terms of economic benefits, the dry direct seeding mode is higher than the machine transplanting mode.

Key words: rice, machine-transplanted seedling, dry direct seeding, yield, yield components
