机械插秧每穴插多少株秧苗,才能达到既省秧、又增产呢?试验表明,机械插秧的穴株数取决于稻秧品种、育秧方式、秧苗素质、插秧规格、插秧保苗率、插秧时间、插秧深度、田间管理水平以及气候条件等。十年生产实践表明,对插秧规格为8×2.5寸的中晚熟品种,其他因素正常时,最佳穴株数为6。此时茎秆高度、茎秆直径、分蘖率、穗长及穗平均粒数 Mechanical seedlings per hole inserted into the number of seedlings in order to achieve both seedling, but also increase it? The test showed that the number of seedlings mechanical transplanting depends on the number of rice seedlings, nursery, seedling quality, planting specifications, seedling seedling rate, planting time, transplanting Depth, field management and climatic conditions. Ten years of production practice shows that the specifications for the transplanting 8 × 2.5-inch medium and late varieties, other factors are normal, the optimal number of holes 6. At this point the height of stems, stem diameter, tillering rate, spike length and average grain number per spike
