在多年小麦种子繁殖生产实践中,各科研、生产单位已经总结了精量播种提高繁殖系数的好方法。在此基础上,为了进一步掌握播量与繁殖系数间的关系,给改进繁殖技术,便于计划生产、科学生产提供参考,以达到快出良种,多出良种的目的,我们1983年做了一个播量与繁殖系数间关系的测验。测验经过 1.处理:共分2.5斤/亩、5斤/亩、10斤/亩15斤/亩、20斤/亩、25斤/亩、40斤/亩等8个播量。 2.设计:小区行长5米、区宽1.5米,面积7.5平方米,行距15厘米,四次重复,随机区组。 3.播种及管理:2.5斤/亩、5斤/亩量分别采用
In many years of wheat seed multiplication and production practices, the various scientific research and production units have summarized the good method of precision sowing to improve the breeding coefficient. On this basis, in order to further understand the relationship between the sowing and breeding coefficients, to provide a reference to improve breeding techniques, facilitate planning and production, scientific production, in order to achieve the purpose of quickly out of good seeds, more seeds, we made a broadcast in 1983 Test of the relationship between quantity and breeding coefficient. Test after 1. Treatment: A total of 2.5 kg / mu, 5 kg / mu, 10 kg / mu 15 kg / mu, 20 kg / mu, 25 kg / mu, 40 kg / mu and other 8 sowing. 2.Design: District governor 5 meters, 1.5 meters wide area, an area of 7.5 square meters, spacing 15 cm, four replicates, random block. 3. Seeding and management: 2.5 kg / mu, 5 kg / mu were used
