大穗型小麦增穗措施

Spike Increasing Measures for Big-Ear Genotype Winter Wheat

针对大穗型小麦分蘖成穗困难的问题,进行了连续多年的田间试验。结合大穗型小麦的生长发育特点和试验结果,总结出"高肥力、早播种、窄行距、适播量、控旺长"的组合增穗措施。

The big-ear genotype winter wheat has high yield potential,however,it is difficult to reach enough spikes in unit area.Several field experiments were conducted to solve the problem.Based on the experimental results and observations of developmental characteristics,the major regulating measures for increasing spikes in unit area as ＂higher fertility,early sowing,narrow row spacing,medium density and late fertilization in spring season＂ were summarized.
