不同类型尿素对青铜峡灌区水稻产量和加工品质的影响

Effects of Different Types of Urea on Rice Yield and Processing Quality in Qingtongxia Irrigation Area

采用田间小区试验研究了不同类型尿素对青铜峡灌区水稻产量和品质的影响。结果表明:与普通尿素(T1处理)相比,新型尿素可以显著提高水稻产量,T3处理(谷氨酸尿素)和T4处理(腐殖酸尿素)子粒产量增产幅度分别为8.10%、6.23%。T2处理(控失尿素)具有一定的缓释效果,满足了水稻营养生长对养分的需求,提高了水稻株高。T4处理(腐殖酸尿素)整精米率最高,比T1处理(常规尿素)提高了3.6个百分点。综合考虑水稻产量和加工品质因素,以T3处理(谷氨酸尿素)效果最好,其次为T4处理(腐殖酸尿素)。

A field experiment was conducted to study the effects of different types of urea on the yield and quality of rice in Qingtongxia irrigation area. The results showed that compared with normal urea （T1）, new-type urea could significantly increase the yield of rice; grain yield of T3 （glutamic acid urea） and T4 （humic acid urea） increased by 8.10% and 6.23% respectively. T2 （loss-control type urea） had a certain sustained release effect on meeting the nutritional needs of rice nutrition growth and increasing plant height of rice. Compared with T1 （conventional urea）, T4 （humic acid urea） had the highest head milled rice rate increasing by 3.6%. Taking the yield and processing quality of rice into consideration, T3 （glutamic acid urea） was the best followed by T4 （humic acid urea）.
