中文摘要	[目的]进行有机营养功能型土壤改良剂配方筛选,研究灰棕荒漠土改良效果和杂交饲用甜高粱经济效益,解决灰棕荒漠土保水、保肥能力弱,有机质含量低,作物产量低而不稳的瓶颈问题。[方法]选择甘肃省酒泉市肃州区的灰棕荒漠土,采用田间试验的方法进行研究。[结果]不同梯度有机营养功能型土壤改良剂施用量与灰棕荒漠土孔隙度、团聚体、持水量、有机质、速效氮磷钾、杂交饲用甜高粱经济性状和产量呈正相关关系,与灰棕荒漠土容重和pH值呈负相关关系。施用有机营养功能型土壤改良剂与施用传统化肥比较,灰棕荒漠土容重和pH值分别降低4.10%和8.27%;总孔隙度、毛管孔隙度、非毛管孔隙度、总持水量、毛管持水量和非毛管持水量分别增加3.63%,3.60%,3.67%,3.63%,3.60%和3.67%;有机质、碱解氮、速效磷和速效钾分别增加7.03%,0.37%,0.33%和0.29%;真菌、细菌、放线菌、蔗糖酶、脲酶、磷酸酶和多酚氧化酶分别增加121.42%,34.69%,20.00%,61.79%,45.37%,36.00%和63.23%;杂交饲用甜高粱穗粒数、穗粒重、百粒重、产量、施肥利润和投资效率分别增加6.38%,4.17%,4.42%和4.04%,2 390元/hm~2和0.40元/元。[结论]施用有机营养功能型土壤改良剂,有效地改善了甘肃省河西走廊灰棕荒漠土理化性质,提高了持水量和杂交饲用甜高粱产量。
英文摘要	[Objective]The study was conducted on the selection of organic nutrition-functional soil conditioners and the economic benefit of hybrid feeding sweet sorghum from application of it,in order to solve the bottleneck problem of grey brown desert soil that is characterized by weak water and fertilizer retention,low organic content and the successive low and unsustainable crop yield.[Methods]The ash brown desert soil in Suzhou District,Jiuquan City,Gansu Province was selected as experimental materials and field experiment was conducted.[Results]The amount of organic nutrition-functional soil conditioner was positively correlated with indices of porosity,aggregate,water holding,organic matter,available nitrogen,phosphorus and potassium,economic benefits and yield of hybrid feeding sweet sorghum,while was negatively correlated with soil bulk density and pH value.Soil bulk density and pH value decreased 4.10% and 8.27% as compared with that of conventional fertilizer.Total porosity,capillary porosity,non-capillary porosity,total water holding,capillary porosity water holding capacity and non-capillary porosity water holding capacity increased by 3.63%,3.60%,3.67%,3.63%,3.60% and 3.67%,respectively;organic matter,available nitrogen,phosphorus and potassium increased by 7.03%,0.37%,0.33%and 0.29%;fungi,bacteria,actinomyces,sucrose,phosphatase and polyphenol oxidase increased by 121.42%,34.69%,20.00%,61.79%,45.37%,36.00%and 63.23%,respectively.The grains per spike,grains weight,hundred-grain weight,yield,fertilizer profits and investment efficiency increased by 6.38%,4.17%,4.42%,4.04%,2 390yuan/hm~2 and 0.40yuan/yuan,respectively.[Conclusion]The grey brown soil physical and chemical properties can be effectively improved by the application of organic nutrition-functional soil conditioners in the Hexi Corridor of Gansu Province,and the water holding capacity,hybrid feeding sweet sorghum yield increased as well.
