随着我国化学工业的发展,国家对农业提供的化学肥料将逐年增加。研究各种农作物的化学肥料施用量、施肥方法和施肥技术,对提高产量和品质以及对国家计划生产化学肥料具有重要的意义。黄麻是以采茎纤维为目的的作物,构成纤维细胞原生质的主要成分是蛋白貭,因此氮肥对提高麻类纤维产量具有重大的作用。据中国农业科学院麻类所研究材料(1959年),黄麻在全生育期,每亩吸收氮素36.91斤、磷酸19.25斤、氧化钾30.5斤。前浙江农科研究所曾进行黄麻肥料三要素试验(1953—1955年)。原麻平均产量:不施
With the development of chemical industry in our country, the chemical fertilizers provided by the state to agriculture will increase year by year. Studying chemical fertilizer application rates, fertilization methods and fertilization techniques for a variety of crops is of great importance for improving yield and quality and for the country’s planned production of chemical fertilizers. Jute is a crop that takes the stem fiber as the main purpose, and the main component that constitutes the protoplasm of the fibroblast is the protein gall. Therefore, the nitrogen fertilizer has a great effect on improving the yield of the hemp fiber. According to the research materials of Chinese Academy of Agricultural Sciences (1959), jute absorbed 36.91 kg of nitrogen, 19.25 kg of phosphoric acid and 30.5 kg of potassium oxide per acre in the whole growth period. Former Zhejiang Agricultural Research Institute has conducted three elements of jute fertilizer test (1953 - 1955). The average yield of raw linen: not applied
