Effect Of Combined Application Of Organic Fertilizer And Chemical Fertilizer On Yield And Quality Of Apple And Soil Nutrient

To explore the apple for the proportion of organic fertilizer and chemical fertilizer with science,will be after high temperature fermentation of organic fertilizer and chemical fertilizer with rabbit dung,under different fertilizer levels in orchard reducing fertilizer,organic fertilizer with new fertilizers,organic fertilizers and reducing of trace element in the conventional fertilizer supplement with experiment,probe into organic fertilizer with growth,yield and quality for apple and apple orchard soil nutrients.The main findings are as follows:(1)Effects of chemical fertilizer reduction on apple yield,quality and soil under different organic fertilizer levelsUnder this experimental condition,along with the increase of the amount of fertilizer applied into apple's production quality has a different degree of increase,but to improve the yield and quality of apple,increase the profit of the farmers,the organic fertilizer into the quantity of 1500 kg/mu chemical fertilizer reduction 20% for the best,compared with conventional fertilization treatment area yield,apple hardness,soluble solid,soluble sugar content,sugar acid ratio increased by 33.45%,8.43%,22.02% and 46.15% respectively,fruit shape index than conventional fertilization increased by 12.20%.Under different levels of organic fertilizer,each treatment of fertilizer reduction can effectively increase the pH value of the soil,making the pH value of the soil increase to the neutral direction.With the increase of the amount of organic fertilizer,the content of organic matter is increased.Compared with conventional fertilization,the pH value,organic matter content,total nitrogen,available phosphorus and available potassium in soil can be significantly increased.According to scientific fertilizer,increase farmers' income and improve fruit quality,H2,that is,organic fertilizer application amount is 20% reduction of chemical fertilizer per mu of 1500kg/mu is the best proportion.(2)Effects of New Fertilizer reduction on Apple yield,quality and soil under the same level of Organic FertilizerUnder the conditions of this experiment,the chlorophyll content,fresh and dry weight of leaves,yield and quality of apples can be improved by 10%~30% reduction of new-type fertilizer and organic fertilizer application.But to improve apple production,quality,increasethe profit of the farmers,the organic fertilizer into the amount of 1500 kg/mu new fertilizer reduction of 30% is the best,compared with conventional fertilization of area yield,apple,hardness,soluble solid,soluble sugar content,sugar acid ratio increased by 18.41% and23.54%,respectively,27.05%,14.99%,30.00%,fruit shape index than conventional fertilization increased by 5.81%.Under the same level of organic fertilizer,the treatment of new fertilizer reduction can improve the acidity and alkalinity of orchard soil,and make the pH value tend to be neutral.Among all the treatments of organic fertilizer reduction,the best effect is 10% and 20% of organic fertilizer reduction,which can significantly increase the content of total nitrogen,available phosphorus and available potassium in soil.According to the principle of scientific fertilizer application,increasing farmers' income,reducing input cost and improving fruit quality,X4 is the best fertilizer ratio with 30% reduction of new fertilizer per mu of organic fertilizer 1500kg/mu.(3)Under the same organic fertilizer level,the effects of trace elements on apple yield and quality and soil were studiedUnder this experimental condition,the conventional fertilizers calcium fertilizer and conventional fertilizer added Ca,Mg,Fe,B treatment can improve apple's trace elements in chlorophyll content,leaf fresh weight and dry weight,yield and quality of the apple,but at the same time to complement the Ca,Mg,Fe,B treatment effect is best,trace elements in area yield,apple,hardness,soluble solid,soluble sugar content,sugar acid ratio increased by 568.8kg,respectively,20.49%,33.63%,77.08%,and the highest fruit shape index,at 0.9.F2 is the best fertilizer scheme to supplement trace elements in Ca,Mg,Fe,B with 1500kg/ mu of organic fertilizer.
