为了发挥高产品种的增产效果,几年来,我们选用不同类型小麦,在不同生态条件下,进行大田和盆栽试验。一、材料与方法 1977—79年田间试验设在武功杨陵公社付家庄队,地力基础据1975年测定:有机质含量0.96％,全氮0.066％,速效磷23ppm,亩产小麦700—800斤。盆栽试验在所内进行。供试品种为冬性、矮杆的小偃5号;弱冬性、高杆的丰产3号;偏春性、高杆的西育7号。 In order to give full play to the yield increase of high-yielding varieties, in the past few years, we selected different types of wheat to conduct field and pot experiments under different ecological conditions. I. Materials and Methods The 1977-79 field trial was conducted in Fuzhuang Zhuang commune of Wugong Yangling Commune. According to the determination of ground force in 1975, the content of organic matter was 0.96%, the total nitrogen was 0.066%, the content of available phosphorus was 23ppm and the yield of wheat was 700-800 kg per mu. Pot experiment is carried out in the house. The test varieties for the winter, dwarf Xiaoyan 5; weak winter, high pole yield 3; spring nature, pole of the West Yo 7.
