| 摘 要： | 为了保证控释肥在水稻生产中的安全施用和水稻专用控释肥的生产改进提供科学依据,通过采用田间小区试验的方法,研究了不同控释肥处理对水稻产量、肥料利用率和经济效益的影响。结果表明,与普通肥相比,等量控释肥、减量控释肥、减氮控释肥、种子保姆肥不能显著提高水稻株高和叶绿素含量;施肥量相近下,控释掺混肥处理土壤养分含量较高;水稻吸收氮磷钾量分别提高5.0%~20.3%、2.7%~40.8%、-8.2%~39.9%;水稻籽粒增产6.90%~15.3%,达显著或不显著水平;氮磷钾利用率分别比普通肥增加6.07%~29.91%、41.86%~85.57%、38.57%~95.43%;田间控释掺混肥处理比普通肥处理每公顷多收入537~1296元。控释掺混肥能有效简化水稻栽培,今后应大力研制和推广水稻专用控释肥料。

| Abstract: | In order to provide scientific evidence for the production and safety application of the special controlled-release fertilizer for paddy rice, field experiment was conducted to study the effects of controlled-release fertilizer on paddy rice yield, fertilizer utilization and economic benefit. The results indicated that: compared with common fertilization, there was no significant difference on the height and lamina chlorophyll content of paddy rice under controlled-release compound fertilizations with various nutrient proportions and different fertilization. Based on the same application of fertilizers, the level of soil nutrient was higher under controlled-release compound fertilizer treatments than under common fertilizations, controlled-release compound fertilization increased the content of N, P and K in paddy rice 5.0%-20.3%, 2.7%-40.8%, -8.2%-39.9%, respectively. The yield of paddy rice increased up to 6.90%-15.3% under controlled-release compound fertilizer treatments. The utilization rate of nitrogen, phosphorus, potassium fertilizers was 6.07%-29.91%, 41.86%-85.57%, 38.57%-95.43%, respectively. The income of paddy rice under controlled-release compound fertilizer enhanced 537-1296 yuan/hm2 in comparison with common fertilization. Controlled-release compound fertilizer could effectively simplified the cultivation techniques of paddy rice, and special controlled release fertilizer for paddy rice should be developed and promoted actively. |
