通过在浙东平原地区主要土壤上连续两年的抛栽早稻施肥技术试验，摸清了抛栽早稻的氮、钾肥适宜用量和施肥方法，并对施用第二次分蘖肥的必要性和施钾抗倒效果作了探讨。 Through two years of throwing planted early rice fertilization experiments on major soils in eastern Zhejiang plain, the appropriate amount of nitrogen and potassium fertilizer and fertilization methods for throwing early rice were found out, and the necessity of applying the second tillering fertilizer and the application of potassium Anti-down effect was discussed.
