秧田播神量试验结果表明,培育壮秧必须稀播,稀播可以增加水稻秧苗的叶龄、单株叶面积、单株根数、单株分(?)数、百株地上部干重和充实度。单位面积内秧苗株数越多,每株秧苗所得到的营养面移就越小。群体中的个体竞争发生就越早,应该根据插秧时秧苗叶龄的大小确定适宜的播种量,叶龄越大,播种量应该越少。稀播少本插,利用秧田分蘖.可以起到以蘖代苗的作用。
Seedling broadcast God amount of test results show that the seedlings must be thinning sowing, thinning can increase the leaf age of rice seedlings, leaf area per plant, the number of single plant, the number of single plant (?), A hundred aboveground dry weight and Fullness. The larger the number of seedlings per unit area, the smaller the nutrient surface shift per seedling obtained. The earlier the individual competition occurs in the population, the appropriate seeding rate should be determined according to the leaf age of the seedling when transplanting. The larger the leaf age, the less the seeding rate should be. Thin broadcast less inserted, the use of tiller seedling. Can play the role of tiller on behalf of the seedlings.
