氮磷不同用量及配比对红花产量的研究

Amount of Nitrogen and Phosphorous Fertilizer and Its Mixed Ratio

合理施肥是红花增加产量、降低成本、提高化肥利用率的一项重要措施。采用方差统计分析方法对1 999～ 2 0 0 0年红花氮磷不同用量及配比试验结果分析研究 ,旨在找出塔城盆地红花氮磷适宜用量及合理配比 ,为红花合理施肥提供科学依据。

Resonable fertilization is an important step for increasing yield, decreusing cost, improving fertilizer utilized coefficient of safflower cultivation. We have carried out an experiment of different utilized amount of nitrogen and phosphorous fertilizer and its mixed ratio of safflower cultivation by the method of analysis of variance in 1999～2000. According to the result, we find the suitable utilized amount and mixed ratio of nitrogen and phosphorous fertilizer and provide a scientific basis for resonable fertilization of safflower cultivation.
