摘 要: | 以黑彤K-8西瓜为试材研究了控释肥对西瓜产量、中心糖/边糖、土壤养分损失的影响。结果表明:控释肥能显著提高西瓜产量,在等养分施用下比习惯施肥增产22.61%,而且在养分减少20%的情况下,仍能增产10.81%;等量控释肥、减量控释肥、减氮控释肥处理的肥料生产率分别是习惯施肥处理的2.14、1.93、1.29倍,中心糖/边糖以及地表径流中的NH4+-N和NO3--N含量均低于习惯施肥处理。由此认为,控释肥是一种增产、经济及对环境友好的肥料。

Abstract: | The field experiment was conducted to study effect of controlled-release fertilizer on yield ,center sugar/limbic sugar、nutrient loss of watermelon with Heitong K-8. The results showed that controlled-release fertilizer could increase watermelon yield significantly ,generally speaking, which increased by 22.61% or 10.81% than that of conventional fertilizer when the same quantity or 80% of fertilizers were applicatied. The fertilizer productivity of treatments of equal controued-realease fertilizer, less controlled-release fertilizer and less nitrogen in controlled-release fertilizer was 2.14 times,1.93 times and 1.29 times of coventional fertilization respectively. In addition,the center sugar/imbic sugar、the content of NH4+-N and NO3--N in the surface runoff were clearly lower than coventional fertilization. It is proposed that controlled-release fertilizer was economic and good for environment and could increase yield the same time. |
