小麦产量受多种因素的影响 ,特别是高产田 ,不但要求高肥力的土壤基础、优良品种 ,还要配合科学地应变管理技术。其中行距配置方式是一方面。以往这方面虽有研究 ,但大部分是在中产水平区进行的 ,而有关亩产 50 0ｋｇ以上小麦的最佳行距配置报道较少。为此 ,1 998～ 1 999年度 Wheat yield is affected by many factors, especially high-yielding fields. It not only requires high-fertility soil foundation and excellent varieties, but also requires scientific management of strain management. One line spacing configuration is on the one hand. In the past, although there were studies in this area, most of them were conducted in the middle-level of middle-class areas, and the best allocation of wheat with a yield of more than 50kg per mu was reported less. To this end, 1 998 ~ 1 999 years
