我所地处浙西,系低丘红壤新造田。1974年前栽培“早熟三号”大麦,亩产在350斤左右。随着土壤的不断改良,1974年试种“908”小麦2.31亩,亩产424斤。1976～1977年扩大到18.8～22.2亩,亩产475.2～409.4斤,1978年47亩,亩产496斤,丰产田亩产超过600斤。本文以丰产田资料为主,就“908”小麦苗蘖动态结构,叶面积及经济系数和产量结构等方面,结合几年来单项试验结果进行分析比较,探讨亩产600斤以上的栽培技术措施。
I was located in western Zhejiang, the Department of red soil in the new fields. Before 1974 cultivated “precocious three” barley, about 350 pounds per mu. With the continuous improvement of soils, 2.31 mu of “908” wheat was planted in 1974, yielding 424 kg per mu. From 1976 to 1977, it was expanded to 18.8-22.2 mu with a yield of 475.2-409.4 kg per mu. In 1978, 47 mu of mu was produced, 496 kg of mu per mu and over 600 kg of mucky crop. In this paper, the main data of high yielding fields, the “908” wheat seedling tiller dynamic structure, leaf area and economic coefficient and yield structure, combined with several years of single test results were compared to explore the cultivation of more than 600 pounds of technical measures.
