钾,是农作物生长发育必需的营养元素之一。在毛主席革命路线指引下,我省钾肥肥效试验的研究工作有了较快的发展,特别是无产阶级文化大革命以来,广大贫下中农和科技人员更加广泛深入地开展了化学钾肥的肥效试验,进一步肯定了钾肥的增产效果与作用,为推广和使用钾肥提供了科学依据。一、钾肥的增产效果近几年,在全省各地进行了570多项次的钾肥肥效试验,结果表明,钾肥对各种农作物都有不同程度的增产作用,其平均增产率
Potassium is one of the necessary nutrients for crop growth and development. Under the guidance of Chairman Mao’s revolutionary line, there has been a rapid development in the research on the fertilizer efficiency test of potash fertilizer in our province. Since the great proletarian cultural revolution in particular, the vast majority of poor and middle-level peasants and scientific and technological personnel have conducted more extensive and in- Affirmed the yield-increasing effect and function of potash fertilizer, which provided a scientific basis for popularizing and using potash fertilizer. First, the yield-increasing effect of potassium In recent years, more than 570 times throughout the province carried out more than 500 times of potash fertilizer test results show that all kinds of potash fertilizer have different levels of yield-increasing effect, the average yield
