南疆玉米茬地免耕播种小麦的表土作业技术研究
Research on the Different Surface Soil Treatment Techniques for No-tilling Seeding Wheat on Corn Stubble Field in Southern Xinjiang
摘要
Abstract
[Objective] This study aimed to explore the surface soil treatment techniques of no-tilling seeding wheat on the corn stubble field in southern Xinjiang. [Method] In the test of no-tilling seeding wheat on the corn stubble field in Luopu County of Xinjiang, 3 treatment modes were designed as "direct seeding after zero-tillage", "zero-tillage sowing after shallow gyration cultivating" and "zero-tillage sowing after digging" and were analyzed and compared through determining the contents of soil moisture, soil volume weight, seedling rate and yield of winter wheat. [Result] The surface soil treatment technique of direct seeding after zero-tillage was basically suitable for the winter wheat on the corn stubble in Southern Xinjiang. Compared with the mode of the traditional sowing after digging, the direct seeding after zero-tillage had greater soil volume weight, but the seeding rate with 2 kinds of sowing modes were very close. The wheat yield by the treatment of direct seeding after zero-tillage was highest, reaching 6 000.99 kg/hm2 and being 6.56% higher than that of zero-tillage sowing after gyration cultivating, that of sowing after digging was next and that of zero-tillage sowing after gyration cultivating was lowest. [Conclusion] Brand "Nonghaha" no-tillage seeder introduced from Hebei Province could be popularized and applied in Hotan prefecture of Xinjiang. After the current corn stubble field in Southern Xinjiang was improved through the matching cultivation technology, it was more suitable to zero-tillage direct seeding of winter wheat.关键词
