Optimization Of The Humic Acid Based Fluid Fertilizer Production Process And Its Effects On Cotton Growth In Drip Irrigated Field

【objective】: With the development of new type of agricultural irrigation technology,integration of irrigation and fertilization has been extended in large area,there have been a variety of fertilizers.Choose a kind of fertilizer which can adapt to integration of irrigation and fertilization,this fertilizer can make the agricultural production increase efficiency is very meaningful.According to the current situation of fertilizer in China,Combined with the actual situation of the soil in Xinjiang,on the basis of the liquid humic acid fertilizer,by selecting of raw materials and improved technology,design a new type of humic acid based fluid fertilizer.Through the field experiment,Verify the effect of humic acid based fluid fertilizer.【methods】: By improving the process,the content of various nutrients in the liquid humic acid fertilizer was improved.The results of the field experiment also proved that the humic acid liquid drip irrigation fertilizer could increase the yield and improve the economic benefit.【results】: On process improvements,improved humic acid liquid drip irrigation fertilizer,all kinds of nutrient content.The results of field experiments also prove that humic acid based fluid fertilizer can improve crop production,and increase the income.【conclusion】:1.After screening,Potassium humic acid,small granular urea,the ammonium phosphate slurry method and Mannheim potassium sulfate as a raw material for production of humic acid liquid fertilizer for drip irrigation.2.According to the raw material after screening,will be in the process of dissolution time,solution temperature,synthesis time,and reflect the semi-finished sieving mesh do improvement,optimize the production process of production of humic acid liquid fertilizer drip irrigation.3.The improved humic acid liquid drip irrigation fertilizer,the content of humic acid content,a large number of elements of nitrogen,phosphorus,potassium and trace elements are improved,higher than the national standard of the Ministry of agriculture.4.The humic acid liquid drip irrigation fertilizer was applied to the drip irrigation cotton experiment,and compared with the local conventional fertilization,the yield increase and the economic benefit was improved...
