Preparation method of biological organic fertilizer for improving flavor quality of Fuji apples

Abstract

The invention discloses a preparation method of a biological organic fertilizer for improving the flavor quality of Fuji apples. The method comprises the following steps: 1, preparing a laminarin enzymatic hydrolysis solution; 2, preparing a fermented cow and sheep dung material; 3, preparing a fermented soybean meal and corn straw mixture material; 4, mixing the laminarin enzymatic hydrolysis solution, the fermented cow and sheep dung material and the fermented soybean meal and corn straw mixture material in proportion, and carrying out secondary fermentation; and 5, air-drying after the secondary fermentation ends, crushing, and carrying out sealed preservation. The biological organic fertilizer is prepared through fermenting different organic raw materials by different microbes, through mixing and through secondary fermentation, is green and efficient, can effectively improve the proportions of soluble sugar and organic acids in Fuji apple fruits, improves the mouthfeel quality, increases the volatile alcohols and ester type fragrance components in the Fuji apple fruits, and improves the fragrance quality. The method is convenient to operate, has extremely high economic and ecologic benefits, and deserves to be widely popularized and applied.

Description

Technical field: [0001] The invention relates to the field of agricultural fertilizers, in particular to a preparation method of bio-organic fertilizer, in particular to a preparation method of bio-organic fertilizer capable of improving the flavor and quality of Fuji apples. Background technique: [0002] With the continuous development of the apple industry, Fuji apple is currently the apple variety with the largest planting area in my country, and its output accounts for 60.4% of the total apple output in my country. As one of the fruits widely loved by consumers, Fuji apple has an absolute advantage in quality, flavor and nutrition, and is closely related to people's health. [0003] Apples are rich in nutrients, ranking first among the four major fruits in my country. The nutritional value of Fuji apple is very significant. According to the determination of the Ministry of Agriculture, the fruit of Red Fuji apple contains 17.2% soluble solids, 0.25% titratable acid, 47...

Problems solved by technology

Rice husk charcoal-based fertilizer can significantly increase the louver weight of Fuji apple leaves, increase the content of chlorophyll b, carotenoids and total chlorophyll in leaves, improve the photosynthetic performance of Fuji apple leaves; control the growth of Fuji apple branches in the same year, reduce nutrient waste, It is beneficial to fruit growth and flower bud differentiation in the coming year; increase the hardness, soluble solids and vitamin C content of Fuji apples, reduce titratable acidity, and increase the sugar-acid ratio of fruits; increase the aroma types of Fuji apples and improve the flavor of Fuji apples. Adjust the effect of rice husk charcoal-based fertilizer to achieve the effect of improving the flavor quality of Fuji apples. The dosage of this invention is 200-300 kg per mu, or 4-6 kg per apple. The dosage is too much, that is, the effect is not efficient enough, especially in the fruit In the early stage, apple trees need a large amount of nutrient supply, and this invention cannot well meet the nutritional needs of Fuji apple trees
