我院多年来进行春小麦丰产试验,目的是探讨宁夏引黄灌区春小麦达到千斤高产的适宜群体动态及其相应栽培技术措施.本文根据1981年的试验,着重探讨高产小麦群体动态的合理指标和达到这些指标的规范化栽培技术措施. 一、丰产田的主要栽培技术措施和产量本实验在宁夏农学院实验农场进行.试验田为淤灌土,质地为重壤,前作玉米,肥
The purpose of this experiment is to explore the suitable group dynamics of spring wheat and its corresponding cultivation techniques to achieve high yield of spring wheat in irrigated area of Yellow River in Ningxia.The paper according to the experiment of 1981, it focuses on the reasonable index of high-yield wheat population dynamics and achieve these The main cultivation techniques and yield of high yield field The experiment was carried out in experimental farm of Ningxia Agricultural College.The experimental field was silting soil with heavy soil texture and the former was maize and the other was fertilizer
