氮磷钾硫肥配施对云烟87的产量效应
Effects of application ratios of nitrogen, phosphorus, potassium and sulfur on the yield of tobacco Yunyan 87
摘要
Abstract
To explore the influence of N, P, K and S mixing fertilization on output of tobacco leaves, a quadratic general rotary unitization design of four factors and five levels was carded out to analyze the single-factor and double-factor effect on Yunyan 87, a high quality tobacco variety in Fujian. Single-factor analysis showed that the output of tobacco leaves increased and then decreased gradu- ally with the increase of the nitrogen and sulfur application respectively, but reversea in the case of potassium, and it always kept going up in the case of phosphorus. Interaction analysis indicated that there existed synergistic effects beween N and P, N and S, P and K, P and S, K and S in a certain range, however, there existed antagonistic effects in the lower and higher range. But the an- tagonistic effects always existed between N and K. The optimal amount in the pot experiment was 3.778 to 4.350 g per pot for N, 3. 608 to 4.125 g per pot for P, 9.860 to 11.635 g per pot for K, 0.818 to 0.942 g per pot for S respectively, and the corresponding ratio of N, P, K, S was about 1：1：2.5：0.2.关键词
