关于水稻产量形成与气象条件的关系,国内外曾进行了许多研究,但地区自然条件和品种不同,产量形成与气象条件关系也有差异。本文以早稻广选3号、红南、湘矮早9号三个品种于82、83年进行的分期播种(从3月7日起每隔10天播一期,共5—6期,各播期设一个重复,顺序排列,小区面积0.03亩,插植规格6×3寸,每蔸插6—8苗,按本地生产田中上水平进行栽培管理)试验为主,结合我站75年以来的早稻分期播种试验结果,通过对不同品种有关生
As for the relationship between rice yield formation and meteorological conditions, many researches have been carried out at home and abroad. However, there are differences in the relationship between yield formation and meteorological conditions in different natural conditions and varieties in the region. In this paper, three varieties of early rice Guangsuan 3, Hongnan, Xiang short morning 9 three varieties in 82,83 years of seeding (from March 7 every 10 days broadcast a total of 5-6, each Sowing a repeat, in order, the plot area of 0.03 acres, planting specifications 6 × 3 inch, 6-8 per 蔸 inserted seedlings, according to the local production level of cultivation in the field management test), combined with my station for 75 years The results of early sowing sowing test results, through the different varieties of students
