Order to clarify the application of biogas, to explore the effect of vegetative growth and fruit quality of apricot and apple trees in different fertilization period, apricot and apple trees foliar spraying the best application of biogas slurry concentration, number of times and in two different application periods fruit trees Gensch Biogas best application, provide the basis for the standardized production of biogas technology as the core of Ecological Agriculture. This study used a the biogas slurry concentration and spraying fertilizer number of two-factor randomized block experiment of almond and apple trees applied foliar fertilizer, as well as through L9 (34) orthogonal test of apricot and apple trees in different application periods Shi root fertilizer. The results show that: the spraying liquid methane on of apricot stem diameter growth, the increase in leaf area and leaf relative chlorophyll content, improve the role, but the impact is not significant. Spraying liquid methane concentration in the fruit quality of apricot fruit weight, longitudinal and transverse diameter, fruit shape index, hardness, soluble solids content, titratable acid and solid acid ratio significantly affected, while spraying the number of biogas slurry apricot fruit fruit weight, longitudinal, transverse diameter, hardness and soluble solids content significantly affected. Help to improve the apricot fruit in the appropriate concentration of biogas slurry suitable fertilization period apricot spraying fruit weight, longitudinal diameter, transverse diameter, fruit shape index, hardness and soluble solids content, lower titratable acidity and improve solid acid ratio, thereby enhancing the quality and improve the taste. Significant indicators of the same concentration and the same number of times by taking into account the maximum processing elected to promote the optimal combination of apricot vegetative growth and fruit quality improvement: a 50% concentration of biogas slurry spray leaf expansion and leaf growth stage once treatment combination. Spraying liquid methane is a relatively new apple tree branch length growth and leaf chlorophyll content increases catalytic role but it is not obvious, and not much impact on the number of pieces of new foliage. Spraying the appropriate concentration of biogas slurry suitable fertilization period is conducive to the improvement of fruit quality, especially in fruit quality, fruit weight, longitudinal, transverse diameter, fruit firmness, soluble solids and solid acid ratio improved significantly, the number of spraying liquid methane on apple fruit, fruit weight, longitudinal and transverse diameter, hardness, and to improve the content of soluble solids a significant effect. Through comprehensive comparisons of biogas slurry to 75% concentration in leaf expansion, leaf growth stage and fruit enlargement of the spray is ideal combination of processing. Gensch Biogas Manure on apricot stem diameter growth, a certain role in promoting the improvement of the increase in leaf area and leaf relative chlorophyll content, but the impact was not significant, of biogas manure apricot fruit fruit weight, longitudinal and transverse hardness and soluble solids content significantly affected, apricot fruit quality of titratable acid content and solid acid ratio had no significant effect. Vegetative growth and fruit quality of fruit trees by taking into account the biogas fertilizer significant indicators and reliable effect fertilization period, may elect the first fertilization (basal) 41666.67kg/hm2, the second fertilization (flowering dressing) 41666.67kg / hm2, the third fertilization (the fruit enlargement dressing) 41666.67kg/hm2 the treatment as a robust apricot tree vigor and fruit quality best treatment. Gensch biogas fertilizer on apple tree vegetative growth promoting effect, but not significant, significant impact on fruit quality. Biogas manure in the external quality of the fruit, fruit weight, fruit length, the transverse diameter significantly in the second year, in two years significant internal hardness and impact of soluble solids in the quality of titratable acid significant impact in the second year. The right amount of biogas fertilizer to improve fruit quality and fertilizer. By taking into account the vegetative growth of anaerobic fermentation residues on fruit trees and fruit quality indicators and reliable effect fertilization period, may elect the first fertilization (basal) 62500kg/hm2, the second fertilization (flowering dressing) 62500kg/hm2 Third fertilization the (fruit enlargement of dressing) 62500kg/hm2 the processing for the best treatment.
