随着农业生产的发展,在水稻高产栽培中大量施钾的实践和低产缺钾坐苗的相继出现与扩大,引起了人们对钾肥的新的注意。一九七三年开始,我们通过省化肥试验网对钾肥肥效进行测定,现将近几年我省钾肥试验和生产的若干情况整理于下: 一、各种作物施用钾肥的效果钾虽是作物三大重要的营养元素之一,但各种作物特性不同,对钾的反应不完全一致。下面是我省一些主要作物的田间钾肥对比试验结果。
With the development of agricultural production, the practice of applying large amounts of potassium in high-yielding rice and the emergence and expansion of low-yield potassium-deficient seedlings have aroused people’s new attention to potash fertilizer. Beginning in 1973, we tested the effectiveness of potash fertilizer through the provincial fertilizer experiment network. In recent years, we have compiled a number of tests and production of potash fertilizer in our province in recent years. I. Effect of Potash Fertilization on Various Crops Potassium One of the most important nutrients, but different characteristics of different crops, the response to potassium is not exactly the same. The following is a comparison of field potash fertilizer test results of some major crops in our province.
