新型尿素对新疆哈密瓜产量、品质及氮肥利用的影响
Effects of New Urea on Yield, Quality and Nitrogen Fertilizer Utilization of Hami Melon in Xinjiang
摘要
Abstract
[Objective] To find out the effects of several new types of fertilizer on the yield, quality and nitrogen absorption and utilization of Hami melon in Turpan, Xinjiang for screening out a new type of urea suitable for the application of Hami melon in Turpan, Xinjiang.[Method]In this experiment, Huangpi 9818 was used as the research object. On the basis of the same nitrogen, phosphorus and potassium (P2O5 140 kg/hm2, K2O 150 kg/hm2), the dry matter, yield, nutrient absorption, nitrogen utilization and quality of Hami melon under several new urea treatments (equal nitrogen amount net urea, equal nitrogen amount humic acid urea, controlled lost urea, equal nitrogen amount zinc urea, and equal nitrogen amount conventional urea plus zinc treatment) under field experiment were analyzed by using common urea treatment as control.[Result]The results showed that the yield of Hami melon and the quality of the dry matter on the ground were increased compared with the ordinary urea treatment. The yield and dry matter of Hami melon after the application of humic acid urea were the highest, 30, 452 kg/hm2 and 2, 724 kg/hm2 respectively. Nitrogen humic acid urea and control urea significantly increased the nitrogen use efficiency of Hami melon and the agronomic efficiency of nitrogen fertilizer. The effect of urea on urea was better, the nitrogen fertilizer utilization rate was 36.08％, the nitrogen fertilizer efficiency was 44.84 kg/kg. Compared with the common urea, equal nitrogen amount net urea, equal nitrogen amount humic acid urea, controlled lost urea, equal nitrogen amount zinc urea, and equal nitrogen amount conventional urea plus zinc treatment could improve the carotene content of Hami melon and the sugar gradient was the lowest.[Conclusion]All factors considered, the application of equal nitrogen amount humic acid urea has the best effect on Hami melon in Turpan, Xinjiang.关键词
