通过分析不同肥料运筹对运棉3539的生长发育及产量构成的影响。研究表明,随着用肥量的减少,产量随之下降。在同样氮肥用量的情况下不同磷、钾配比产量表现不同,在高肥情况和低肥情况下均表现为磷肥用量增加产量提高,反之降低。在同样肥料用量情况下,随着追肥时期不同,产量表现不同。
Through analyzing the effects of different fertilizers on the growth and yield components of 3539 cotton. Research shows that, with the reduction of fertilizer, the yield decreases. Under the same amount of nitrogen fertilizer, the yield of different phosphorus and potassium fertilizers showed different performance. Under the condition of high fertilizer and low fertilizer, the yield of phosphate fertilizer increased and the yield decreased, on the contrary. In the same amount of fertilizer, with the different times of top dressing, yield different performance.
