摘要: 【目的】 研究不同施氮量对设施甜瓜生长发育和养分吸收利用的影响,为设施甜瓜生产确定氮肥最佳施用量、提高化肥利用率和化肥减施增效提供参考。【方法】 以新疆吐鲁番地方品种西开心甜瓜为试材,在设施条件下以不施氮肥和常规施肥为对照,分析不同施氮量处理对甜瓜生长发育及氮素吸收利用的影响。【结果】 以施入一定磷钾肥为基础,植株主蔓和茎粗生长在生育期内表现为为“慢-快-慢”3个阶段的“S”型生长曲线,主蔓长度与施氮量成正比,随着施氮量的增加,植株茎粗、果实纵径、横径及氮素吸收量均表现为先增加后减小的趋势,优化施肥与常规施肥相比,氮素吸收率提高32.79%,氮肥利用率提高11.63%。氮素过量施用会导致氮肥对产量贡献率、氮肥农学效率、氮肥偏生产力、氮肥生理利用率和氮产投比都降低。【结论】 在保证甜瓜产量和品质的基础上,以优化施肥为基础,配方施肥,增施有机肥,根据甜瓜生长结果需肥规律,氮磷钾肥科学合理配施,实现氮肥的高效利用,提高氮肥利用率,减施化肥和农药,降低生产成本。

Abstract: 【Objective】 To study the effects of different nitrogen application rates on the growth, development and nutrient absorption and utilization of protected melon in the hope of providing reference for determining the best nitrogen application rate, improving the utilization rate of chemical fertilizer and reducing the application efficiency of chemical fertilizer. 【Methods】 muskmelon, a local variety in Turpan, Xinjiang, was used as the test material to analyze the effects of different nitrogen application on the growth and development of muskmelon and the nitrogen absorption and utilization under the condition of facility. 【Results】 Based on the application of a certain amount of P and K fertilizer, the growth curve of main vine and stem diameter in the growth period was "slow fast slow" three stages, and the length of main vine was in direct proportion to the amount of nitrogen application. With the increase of nitrogen application, the plant stem diameter, fruit vertical diameter, horizontal diameter and nitrogen absorption increased first and then decreased, and the optimized fertilization, compared with conventional fertilization, the nitrogen absorption rate and nitrogen utilization rate increased by 32.79% and 11.63% respectively. Excessive application of nitrogen reduced the contribution rate of nitrogen to yield, agronomic efficiency of nitrogen, partial productivity of nitrogen, physiological utilization rate of nitrogen and the ratio of nitrogen production to investment. 【Conclusion】 On the basis of ensuring the yield and quality of muskmelon and on the basis of optimizing fertilization, formula fertilization was carried out according to the soil fertility to increase the application of organic fertilizer. And according to the law of fertilizer requirement for melon growth results, nitrogen, phosphorus and potassium fertilizer should be applied scientifically and reasonably to realize the efficient utilization of nitrogen fertilizer, improve the utilization rate of nitrogen fertilizer, reduce the application of chemical fertilizer and pesticide, and reduce the production cost in Turpan, thus efficiently increasing farmers' income and providing technical guarantee.
