【摘要】 为提高玉米产量、改善玉米品质、实现减肥目标,根据玉米生长发育的营养需求,设计了玉米均衡营养肥并开展了田间试验。通过测定不同施肥处理的玉米单产、百粒质量以及干物质、淀粉、类胡萝卜素含量等指标,探讨了玉米均衡营养肥对玉米产量和品质的影响。结果表明:施用玉米均衡营养肥,与对照处理相比,玉米单产提高了3.28%～10.02%,同时促进了玉米中抗氧化物质类胡萝卜素的合成;施用玉米均衡营养肥可以大幅减少氮、磷、钾肥的施用量,减轻土壤盐渍化和板结,有利于修复土壤生态。更多还原

【Abstract】 In order to increase maize yield, improve maize quality and achieve the goal of reducing fertilizer application, a balanced nutritional fertilizer for maize is designed and field experiment is carried out according to the nutritional requirements of maize growth and development. The effects of maize balanced nutrient fertilizer on the yield and quality of maize are discussed by measuring the maize yield, 100-seed weight, dry matter, starch, carotenoid content and other indicators of different fertilization treatments. The results show that the application of balanced nutrient fertilizer for maize increases the yield of maize by 3.28%-10.02% compared with the control treatment. At the same time, the synthesis of antioxidant carotenoids in maize is promoted. The application of maize balanced nutrient fertilizer can significantly reduce the application amount of nitrogen, phosphorus and potassium fertilizer. Furthermore, the soil salinization and hardening situation can be reduced and therefore benefical to the restoration of soil ecology.更多还原
