Developement Of Fungus Chaff Compound Fertilizer And Its Application In Cultivation Of Strawberry

In this paper,the compound fertilizer of bioactive bacteria was made by mixing with chicken manure and adding probiotics.The effect of compound fertilizer on growth and quality of strawberry was tested,and the reuse of disused bran is realized.Firstly,three kinds of bacteria（1,2,3）were screened from the Waste degradation fungus powder.Analyzed the three kinds of strain capacity of H₂S,NH₃,four kinds of macromolecular organic matter degradation ability,pHospHate-solubilizing,releasing and nitrogen fixation ability,and studied the three strains of high temperature,high salt and pH value of tolerance.With the identification,the first strain was identified as Bacillus cereus Frankland and Frankland,the second strain was Bacillus subtilis,and the third strain was Bacillus megaterium.The three strains were mixed and cultured,and the total number of bacteria in mixed culture was observed,and the mixture of 4 x10⁹ cfu/mL was prepared.Secondly,research and identified the best prescription of fungus chaff compound fertilizer.The fungus chaff and ratio of chicken manure to strawberry plant growth and fruit quality in the process of impact was analysed by single factor pot experiment.The indoors experiment was divided into six groups,which regularly fertilized and measured the growth indexes of strawberry plants and the quality indexes of the fruit.Results show that the fungus chaff with chicken manure in accordance with the ratio of 2:3 after mixed fermentation,the concentration of added to the mixture of 4 x10⁹ cfu/ml bacteria agent preparation of fungus chaff compound fertilizer to promote the growth of strawberry and improve fruit quality effect is most obvious.Finally,a single-factor random group experiment was conducted to test the effect of different fertilizers on strawberry planting in the field.Five fertilizer treatments were set up,the other field management measures were the same,and the nutrition growth,yield and fruit quality were recorded.The raw data analyzed by Using EXCEL2007,and the variance analysis,multiple comparison analysis and mapping of the indicators were analyzed using statistical software SPSS17.0.The results showed that the compound fertilizer could promote the growth of strawberry plants and improve the yield and quality of strawberry fruit.Application of bacterial chaff compound fertilizer than the control group compared to the same amount of farmyard manure,a 20%increase in plant height,leaf area increased 32%,single fruit weight increased by 32%,plant yield increased by 28%,soluble sugar content increased by 15%,vitamin C content increased by 23%.Compared with other conventional fertilizer application of bacterial chaff compound fertilizer,plant height increased by 12%,the most simple the largest area increased by 13%,weight can be increased by 27%at most,most plant production increased by 28%,soluble sugar content increased by 31%,most vitamin C content increased up to 12%.At the same time,the soluble acids were reduced from 17%to 30%in the same amount of conventional fertilizers.
