不同播种情况下谷子出苗率差异性分析

为了给谷子简化栽培提供一些理论依据，探明谷子出苗是否需要“群体顶土”协助，特做了本项研究。连续2 年在条播、穴播、不同播深、不同播量等情况下，对谷子出苗率进行调查，并统计分析其差异性。试验结果表明：只要在相同的种植条件下，谷子的出苗率与播量没有关系。通常在整地质量较好、土壤墒情较好的情况下，每公顷播量4 kg 左右就能达到生产用苗数，基本可以做到少间苗或不间苗。谷子出苗不需要“群体顶土”协助。

Differentiation Research on Seedling Emergence Rate of Millet Under Different Sowing Modes

In order to provide theoretical basis for simplified culture technique of millet, this study was conducted to investigate whether the millet seedling emergence needed group power to break through the soil. An investigation and a statistical analysis of millet seedling emergence rate were carried out for two consecutive years under different sowing modes, such as drilling and dibbling, and different sowing depth and quantities. The results showed that the seedling emergence rate of millet had nothing to do with the sowing quantity under the same planting condition. If the soil preparation and moisture were good, the sowing quantity of about 4 kg/hm2 was suitable to forming appropriate seedling number in the farming, basically meet the requirement for less thinning or no thinning. The millet seedling emergence did not need group power to break through the soil.
