玉米是我省优势作物,分布广,面积大,产量高,左右粮食生产大局,和人民生活密切相关,对畜牧业和工业发展至关重要。我省气候、生态条件复杂,形成春播、夏播和套种等多种多样栽培形式,又有单作和间作之分,套种玉米也因播期和株行距布局不同分为多种类型。各类玉米因播期、生态环境的不同而各具独特的生育规律和栽培技术。本文试图以玉米高产原理和实践经验为依据,寻找各类玉米田高产的基本规律。一、玉米高产的三原理作物干物质产量约95％是来自光合产物,所以尽管各类玉米田的栽培技术有所不同,但其共同点都是围绕提高光合生产而进
Maize is the dominant crop in our province. It is widely distributed, large in area and high in output, and is closely related to people’s livelihood. It is of vital importance to animal husbandry and industrial development. The climate and ecological conditions in our province are complex and form a variety of cultivation forms such as spring sowing, summer sowing and intercropping. There are also single cropping and intercropping. The intercropping corn is also divided into many types due to the different sowing dates and the spacing of rows and rows. Various types of maize due to different sowing times, different ecological environment and a unique law of fertility and cultivation techniques. This paper attempts to base on the principle of high yield of corn and practical experience to find the basic law of high yield of all kinds of corn fields. First, the high yield of three principles of crop dry matter yield of about 95% from photosynthetic products, so although the cultivation of various types of corn fields are different, but their common ground is to improve the photosynthetic production
