氮磷肥对歪头菜产量和品质的影响
Effects of different nitrogen and phosphorous fertilizer on yields and nutrients of Vicia unijuga
摘要
Abstract
The experiment was performed to investigate the influences of nitrogen （0, 50, 75, 100kg·hm-2） and phosphorous （0, 70, 140, 210 kg·hm-2） fertilizer on nutrients and yields of Vicia uniju- ga. It was found that both 75 kg·hm-1 nitrogen fertilizer and 140 kg·hm-1 phosphorous fertilizer could maximize the dry matter yields of V. unijuga, the highest yield was 3 048 and 2 752kg·hm-1, respectively. The yields were 50% and 35% higher than those with no fertilizer, respectively. In addition, by using 75 kg·hm-1 nitrogen fertilizer and 140 kg·hm-2 phosphorous fertilizer, the contents of Cu, Mn and Zn elements were much higher than those without fertilizer （P〈0.05）. Under the 50 kg·hm-1 nitrogen fertilizer and 70 kg·hm-1 phosphorous fertilizer, the contents of water soluble sugar and crude protein were all the highest. The contents of water soluble sugar and crude protein in 50 nitrogen were 11. 0% and 23.5 % higher than those without nitrogen. It should be noted that excessive amounts of nitrogen or phos phorous fertilizer would decrease the yield and quality of V. unijuga, and the actual amount of fertilizer should be considered in practice.关键词
