摘要
采用方差分析、线性回归分析及农业经济效益评价方法,分析了直播、水育密植、旱育稀植和抛秧栽植不同栽培方式水稻生产力水平、产量稳定性及其经济效益,提出张掖市应重点实施推广抛秧栽植并辅以旱育稀植的水稻栽培方式,淘汰水育密植和直播水稻方式的建议。
In terms of evaluation method of agro-economic benefits and analysis of variance and linear regression, productivities, the stability of yields and economic benefits of rices that are cultivated in the ways of direct seeding, water-heavy seeding,dry-light seeding and throw-ing seeding are analyzed. The advices that the throwing seeding technique should be spread on, with partly dry-light seeding,and the water-heavy seeding and direct seeding should be ob-soleted,are raised.
