我省粮食生产近几年来有较大发展,但就绝对数量看仍属低水平。如何在粮食作物上合理施用氮磷钾化肥,研究其适宜用量及合理配比实属必要。为此,按照全国化肥试验网统一设计处理方案,1984年在省内部份专(州)中的19个点进行了试验。其中水稻试验11个,玉米试验8个。现将试验结果简结于后。 一、试验设计与进行情况 各试点化学肥料用量统一为全氮8公斤/亩,五氧化二磷4公斤/亩,氧化钾4公斤
In recent years, grain production in our province has made great progress, but the absolute quantity is still at a low level. How to apply NPK fertilizers reasonably on food crops is necessary to study its suitable dosage and reasonable proportion. To this end, in accordance with the National Fertilizer Experimental Network unified design and treatment programs, 1984 in some provinces (prefectures) 19 points were tested. Among them, 11 rice trials and 8 corn trials. Now concludes the test results. First, the experimental design and implementation of the pilot amount of chemical fertilizer uniform for the total nitrogen 8 kg / mu, phosphorus pentoxide 4 kg / acre, potassium 4 kg
