| 摘 要： | 在冀中南平原地区低锌低锰低硼土壤不同作物上施用涂层尿素配合微量元素锌、锰、锌锰或硼。比涂层尿素有显著的增产作用,而且能够改善植株性状,提高产品品质。与涂层尿素相比,配施锌涂层尿素、配施锰涂层尿素、配施锌锰涂层尿素在冬小麦上施用分别平均增产5.6%,6.1%和13.7%,在夏玉米上施用,分别增产11.0%,2.3%和6.8%,且植株穗部性状得到改善,穗粒数、千粒重等显著提高。棉花施用配锌锰涂层尿素和配硼涂层尿素后,分别比单施涂层尿素平均增产13.3%和11.3%,蕾铃脱落减少,纤维和衣分增加。并探讨了不同作物适宜配施的不同微量元素。 |

The Effects of Coated Urea Mixed with Micronutrients on the growth of the Main Crops in Hebei Province |
|
| Abstract: | Some new fertilizers, coated urea (CU) mixed with some micro nutrients Zn, Mn and B, were studied for their effect on the growth of the main crops in the midland and southern land of Hebei. The results indicated that these fertilizers could obviously improve the yield and quality of winter wheat, maize and cottons, compared with the typical urea . The increased yields from Zn-CU, Mn-CU and Zn Mn -CU were 5.6%, 6.1% and 13.7% respectively for winter wheat, and 110%, 2.3% and 6.8% for maize. ZnMn -CU and B-CU had the same effect on cotton as the increased yields from those two types of urea were13.3% and 11.3% respectively. The ear properties of the crops and cotton fibers were greatly improved after applying theses new of fertilizers. |
