沿黄地区稻茬麦受前茬水稻收获晚的影响,加上地势低洼易涝,小麦常年不能适时播种。为了探讨在晚播条件下稻茬麦的生育规律及高产途径,自1981年以来,在郑州地区对稻茬麦进行了高产栽培试验和多点调查,总结出了亩产300～400公斤的群体动态指标及关键技术,现简述如下。一、不同生育时期的长相指标 The rice crop along the Yellow River is affected by the late harvest of the former crop of rice, together with the low lying and easy waterlogging, the wheat can not be seeded timely. In order to investigate the fertility rule and high-yielding ways of rice stubble under late-sowing conditions, since 1981, high-yielding cultivation experiments and multi-point surveys have been conducted on rice stubble in Zhengzhou area, and the population of 300-400 kg per mu Dynamic indicators and key technologies, are summarized below. First, different length of growth indicators
