近年来,推广小麦密植后,在依靠主茎与依靠适当分蘖增产问题上,及有关分蘖的位次、多少与主茎产量和整株产量的关系上,意见常是分歧的。为了对此问题得出一些正确认识,1959年在两块面积各为10亩左右的南大2419小麦地段上,于收获前两天,我们对植株的生长和发育,按有效分蘖数的多少,分组进行了分析。共结果是: (1)一次有效分蘖的结实小穗数与结实粒数比主茎少,但其分蘖愈多的,不仅不因分蘖加多而降
In recent years, the popularization of wheat planting, relying on the main stem and rely on the appropriate tiller and yield issues, and the relevant tiller number, the main stem yield and the relationship between the yield of the plant, the views are often divided. In order to arrive at some correct understanding of this issue, in 1959 in two areas of about 10 acres of Nanda 2419 wheat lots, two days before harvest, we plant growth and development, according to the number of effective tillers, grouping Analyzed. The total results were: (1) The number of effective spikelets and effective grain number of effective tillers was less than that of main stems. However, the more tillers, the more tillers
