固体活性有机肥对河西内陆灌区玉米田理化性质和经济效益的影响
Effect of solid active organic fertilizers on physicochemical properties and economic benefits of corn field in Hexi inland irrigation district
摘要
Abstract
An experiment was conducted in the field with eight-year continious com planting in Xexi inland irrigation district of Gansu to study the relationship between the amount solid active organic fertilizer and physicochemical properties of corn field and economic benefits of corn production. The results show that: the best combination of solid active organic fertilizer is furfural residue: 45 t/hm , cow dung: 67.50 t/hm , bio-fertilizer: 0.06 t/htn , polyvinyl alcohol: 0.03 t/hm2, water retention agent: 0.06 t/hm2; The amount solid active organic fertilizer was positively correlated with soil porosity, aggregate structure, water storage, content of organic matter, available phosphorus and potassium and EC, while it was negatively correlated with soil bulk density and pH; With the increase of solid active organic fertilizer, the corn yield increases, but the increasing amount resulting from per unit (1 kg) solid active organic fertilizer, declines a-long with the increase of the fertilizer, presenting the law of diminishing returns; On the basis of the amount of 112 t/hm2 solid active organic fertilizer, additional 28.00 t/hm2 fertilizer brings about negative profit margin; Through regression analysis, it is found that the best application rate of solid active organic fertilizer is 111 .40 t/hm2, when the theoretical corn yield is 7.28 t/hm2.关键词
