1976—1977、1977—1978年度,我们把分期播种方法应用于良种良法的研究.1976—1977年度参试品种有我院新育成品种(系)宁麦3号、4号、5号,宁麦7317小麦和早熟3号大麦;1977—1978年度又增加了我省主要推广品种浙114元麦和扬麦3号、泰山1号小麦.播种分四期:Ⅰ.10月26日,Ⅱ.11月5日,Ⅲ.11月15日,Ⅳ.11月25日.小区行长12尺,行距0.7尺,7行区(1976—1977年度为6行区,行距0.8尺),小区面积0.1亩.未设重复.开沟条播,播量根据种子发芽率、千粒重,按每亩20万基本苗计算.施肥量接近丰产田水平.
In 1976-1977 and 1977-1978, we applied the staging method to the study of improved varieties and good methods. The varieties tested in 1976-1977 were: Ningmai 3, No.4 and No.5, Ningmai 7317 wheat and precocious barley No. 3; 1977-1787 added another major varieties of Zhejiang Province, Zhejiang 114 wheat and Yangmai 3, Taishan No. 1. Sowing in four phases: I. October 26, Ⅱ.11 November 5, November 15, Ⅳ. Nov. 25. The district president is 12 feet and the line spacing is 0.7 feet. In the 7-line area (6-row area in 1976-77, with a row spacing of 0.8 feet), the plot area is 0.1 mu No repetition, no tillage, sowing rate is calculated according to seed germination rate and 1000-grain weight per 200,000 basic seedlings per mu.
