不同叶龄抛栽对免耕抛秧稻产量的影响试验

The Experiment of the Influences of Throwing Cultivation of Different Leaf Age on the Output of Till-less Seedling Throwing Rice

试验结果表明 ,免耕抛秧稻在不同叶龄抛栽 ,早抛早立苗、早分蘖、早成熟 ,迟抛迟立苗、迟分蘖、迟成熟 ,2 5～ 3

The experiment results showed that the throwing cultivation of till-less seedling throwing rice under different leaf ages showed the following results: the earlier throwing made the earlier standing of seedlings, earlier tillering and earlier maturation.The late seedling throwing made the late standing of seedlings, late tillering and late maturation.The output was the highest when the seedlings had their leaf age of 2.5-3.5 leaves in throwing cultivation.
