春小麦是内蒙古干旱半干旱地区的主要粮食作物,由于水资源缺乏,农业用水已经受到限制。这就需要我们改变过去那种只谋求高产寻求丰产时的灌溉定额,而不算水利经济帐的作法,本文就适用于田间试验的、建立在系统工程基本思想方法上的一种简单计算法——边际分析,来探讨春小麦的经济灌溉定额,并以此指导生产。一、基本思路及试验方法我们从灌区现有条件出发,在农业生产力水平适中条件下,对灌区常出现的和可能
Spring wheat is a staple food crop in the arid and semi-arid regions of Inner Mongolia. Agricultural water use has been limited due to lack of water resources. This requires us to change the past, which only seeks to seek high yield irrigation yield, rather than the practice of water conservancy accounts. This article applies to field experiments, based on the basic idea of systems engineering method of a simple calculation - - Marginal analysis to explore the economic irrigation quotas of spring wheat and to guide the production. First, the basic ideas and test methods We start from the existing conditions in the irrigated area, under the conditions of moderate levels of agricultural productivity, irrigated areas often appear and may
