Abstract
[Objective] The aim was to explore the optimal fertilization way of N, P and K in high yield production of millet. [Method] With Zhangza 10 as material, effects of N, P and K fertilizer management on the quality and yield of millet were studied. [Result] The results showed that the highest yield of N was in N4 treatment, N fertilizer application amount was 225 kg/hm2 , yield was 7 443. 55 kg/hm2 . The highest yield of P was in P5 treatment, P fertilizer dosage was 240 kg/hm2 , yield was 6 800. 45 kg/hm2 . The highest yield of K was in K4 treatment, K fertiliz-er application amount was 90 kg/hm2 , yield was 7 180. 16 kg/hm2 . Increasing the amount of N fertilizer can significantly improve the yield, grain weight per spike, 1 000-grain weight and the content of protein and carbohydrate, decrease fat and fiber content. Increasing the amount of P fertilizer can help to improve yield and protein, fiber content and decrease fat content. Increasing the amount of K fertilizer can improve yield and ash, carbohydrates, fat and fiber content, reduce protein content. [Conclusion] N fertilizer is the most important factor, combined applica-tion of P, K and N fertilizer can increase the yield.关键词
