多功能玉米专用肥筛选及改土培肥效果研究
Study on Screening of Corn Special-fertilizer with Multi Function and Effect of Soil Amelioration by Fertilizer Application
摘要
Abstract
According to the specialty-fertilizer with multi functional were designed for sandificational of farming corn seed in Hexi irrigation areas, using pot experients to study the prescription formulation and effect of soil amelioration by fertilizer application. The results showed that the optimal combination of cow fertility, furfural residue, fertilizer, polyvinyl alcohol, insurance agent, the dosage were 3 480, 2 667, 462, 39, 21 mg/soil 1 000 g, mix ratio 520∶400∶71∶6∶3. The application of corn special-purpose with multi function can improve the total porosity, capillary porosity, non-capillary porosity, >0.25 mm aggregates, natural moisture content, water content, organic matter of farming aeolian and other physical and chemical properties, can decreasthe bulk density, soil pH, can significantly promote the growth of maize seedlings. The results also indicated that the best formula of applied to multi-specialty fertilizer was 7 042.25 kg/hm2, the equivalent yield of 5 691.20 kg/hm2, and 472.0 kg/hm2 and 9.06%higher than of the traditional application of N, P2O5 content to Fertilizer, it will increase income 238.55 yuan/hm2.关键词
