An Application of Combined Fertilizer with Soybean Meal Manure to Corn Seed Production Field in Zhangye of Gansu Province
摘要
Abstract
In a 13-year continuous corm planting field , a study concerning the influence of combined fertilizer with soybean meal ma-nure on soil properties and corn yield of Jixiang No .1 was conducted in Ganzhou district , Zhangye of Gansu Province .The results showed that the corn yield with different fertilizer application was in a order of zinc sulfate >corn fertilizer>soil yeast manure>soybean meal manure;an optimal fertilizer combination was as follows: zinc sulfate 60 kg・hm-2 , soil yeast manure 300 kg・hm-2 , soybean meal manure 4 500 kg・hm-2 , and corn fertilizer 1 320 kg・hm-2; the regression equation between the combined fertilizer with soybean meal manure and the corn yield was: y=5.66+0.465 1 x+0.023 2 x2 , with 4.7 t・hm-2 of the optimal yield and 8.36 t・hm-2 of theoretical yield.Compared with conventional fertilization , the combination fertilization decreased 3.5% of soil bulk density and 1%soil pH , respectively;increased 6.4%of soil total porosity , 11.7%of soil aggregate and 6.4%of soil water retention , respective-ly;added 1.5%of soil organic matter , 1.1%of soil alkali-nitrogen , 4.2%soil available P and 6.2% of soil available K , respec-tively.Also, the amount of fungal , bacteria, actinomycetes and total microorganism raised 121.4%, 34.8%, 20.5%and 28.6%, respectively;soil sucrase, urease, phosphatase and polyphenol oxidase increased 62.2%, 44.9%, 37.9% and 62.5%, respec-tively.Moreover , plant height , stem diameter , growth rate and aboveground dry weight increased 14.8%, 24.3%, 14.7% and 41.8%, respectively;ear-corn seed number , ear-corn seed weight and hundred seed weight increased 5.4%, 12.7%and 12.9%, respectively.Finally, yield and fertilization profit increased 12.7%and 1 489.02 RMB yuan・hm-2 , respectively.关键词
