在提高油菜单产的综合栽培技术中,施肥是发挥油菜增产潜力的重要一环。了解油菜的营养生理,了解各种肥料的施用对油菜产量和品质的影响和效应,是改进油菜施肥技术的理论和依据。一、氮、磷、钾、硼营养元素对油菜生长发育的影响氮氮是植株体内蛋白质的主要组成物质。它不仅是形成细胞内的酶和叶绿素必不可少的物质,而且能使原生质增加,增大细胞体积,从而使叶面积增长,光合作用加强。在没有其它因素限制时,油菜植株生长旺盛,开花繁茂,能形成更多的角果。由于
In the comprehensive rapeseed cultivation techniques to improve yield, fertilization is an important part of rapeseed production potential. To understand the nutrition physiology of rapeseed and understand the influence and effect of various kinds of fertilizers on rapeseed yield and quality is the theory and basis to improve rapeseed fertilization technology. Nitrogen, phosphorus, potassium, boron nutrient elements on the growth and development of rape Nitrogen and nitrogen are the main components of plant protein. It is not only an essential substance for the formation of intracellular enzymes and chlorophyll, but also can increase the protoplasm, increase the cell volume, so that the leaf area increased, photosynthesis strengthened. When there are no other constraints, rape plants grow vigorously and bloom to form more pods. due to
