玉米高产高效群体调控技术研究概述
Study on the Control Technology of High Yield and Efficiency Population with Maize
摘要
Abstract
Increasing density is the main way to achieve Maize high yield and high efficiency,however,it also brings lodging,empty stalk,early senescence and other a series of problems,hindered the exploration of maize yield.In this paper,we analyzed the effluences on establish mechanization high density planting and high yield population,just as the density-tolerance of varieties,sowing quality,canopy structure,subsoiling, fertilizer application and so on;explored the coordination optimization technique between canopy and topsoil of high density planting population.Pointed out that choose density-tolerance variety to improve population bio-mass,guarantee sowing quality to improve the population uniformity,adjust row and plant spacing to improve population photosynthesis capacity is an important means to optimize canopy structure and establish high effi-ciency population.Subsoiling every other year,deep application of fertilizer,combine application of organic and inorganic fertilizers is the important way to control the topsoil.关键词
