海河平原是我国重要的小麦产区。2004年以来,在该区域进行小麦超高产(9 000kg/hm2)典型创建的基础上,对超高产冬小麦的生育特性和栽培技术参数进行测定,并设置田间析因试验进行研究。明确了超高产小麦的品种类型和产量结构、群体性状及其共性特征、个体形态和生理性状特点以及超高产冬小麦对氮、磷、钾、硫、锰、锌、铜、硼等无机营养元素的吸收、积累和分配特点。明确了实现小麦玉米两茬均衡超高产的适宜接茬方式及实现冬小麦超高产的播种期、密度、种植形式和水肥运筹技术,对实现冬小麦超高产的综合栽培生态条件进行了探讨,建立了海河平原冬小麦节水超高产栽培技术体系。技术体系体现在河北省的小麦生产技术规程及农民技术培训内容中,作为小麦生产的技术支撑,在小麦生产中发挥了重要作用。
Haihe River Plain is an important wheat producing area in China. Since 2004, on the basis of the typical super-high-yielding wheat (9 000 kg / hm2) in the region, the fertility characteristics and cultivation techniques of super-high-yielding winter wheat were determined and the field factorial experiment was set up. The varieties and yield structures, population traits and their common characters, superposition and physiological characteristics of super-high-yielding wheat and their effects on nitrogen, phosphorus, potassium, sulfur, manganese, zinc, copper, boron and other inorganic nutrients Absorption, accumulation and distribution characteristics. It is clear that the appropriate cultivation methods to realize the balanced high yield of wheat and wheat and the sowing date, density, planting form and technology of water and fertilizer for the super high yield of winter wheat are discussed. The comprehensive cultivation ecological conditions to achieve super high yield of winter wheat are discussed. The Haihe River Plain Winter Wheat Water Saving and Super High Yield Cultivation Technique System. The technical system is embodied in the wheat production technical regulations and peasant technical training contents in Hebei Province. As a technical support for wheat production, it has played an important role in wheat production.
