一种检验影响农作物单产因素的方法

A Method of Determining the Factor Influencing Per Unit Yield of Crops

据不完全统计,当今世界大多数国家或地区,用于粮食生产的耕地面积逐年递减。如何利用有限的耕地面积,在不影响生态平衡和控制生产成本的前提下,使单产达到一个新的水平,就显得尤其重要。作物种类、肥料用量、土壤肥沃度、生产年度是影响某一地区粮食单产的主要因素。收集历史资料,选择测试地点,使用套分析法,检验这些因素对单产的影响。根据检验结果,寻找增产的途径。

According to an uncomplete statistics, at present most of countries or areas in the world own less and less cultivable areas. It is important that how to employ limited cultivable areas to make per unit yield attain maximum without influencing ecological system and controlling production cost. Crop variety, fertilizer dose, soil condition and production year are main factors influencing per unit yield. The test is embarked to make sure whether per unit yield is greatly influenced by these factors of collecting information, selecting trail place or using nest method and to seek the way to increase it on the basis of test result.
