我省棉花栽培面积已达1200万亩。其产量的高低,品质的好坏,直接影响人民的生活及工业的发展。因此,在提高棉花产量的前提下,如何改进品质是当前十分迫切的任务。钾素是棉花生育所必要的营养元素之一,对增加产量与改进品质有一定的作用。为此于1981年开始,与有关单位协作,从事钾肥肥效与施用技术的试验研究工作。现将三年来试验结果报道于后。
Cotton cultivation in our province has reached 12 million mu. The level of its output, quality is good or bad, a direct impact on people’s lives and industrial development. Therefore, under the precondition of increasing cotton production, how to improve the quality is a very urgent task at present. Potassium is one of the nutrients necessary for the growth of cotton and plays a role in increasing yield and improving quality. To this end in 1981, in collaboration with the relevant units, engaged in fertilizer research and application of fertilizer efficiency and experimental work. Now three years after the test results reported later.
