Application of compound biological agent in promoting quality of vegetable products

Abstract

The invention discloses application of a compound biological agent in promoting quality of vegetable products. The compound biological agent is prepared from bacillus subtilis fermentation liquor, trichoderma pseudokoningii fermentation liquor, water-soluble chitin, aginomoto residue and potassium fulvic acid. An experimental result proves that the strawberry treated with the compound biological agent, compared with the control group, has the advantages of obviously increased weight of single fruit, soluble solids, soluble sugar, titratable acid content and solid acid ratio. The invention aimsat researching the practice feasibility and production operability; the compound biological agent meeting the national standard for organic products is applied in the growth season of the strawberry;the compound biological agent is sprayed onto the leaves at regular intervals according to the growth characteristics of the strawberry, so that the purpose of improving the strawberry quality is achieved. The probiotic has a certain function of preventing and controlling the crop plant diseases, so that a planter is willing to use the method; no additional labor cost or equipment cost is added;the quality of the vegetable products is increased; the operation is easily mastered; the popularization is strong.

Description

technical field [0001] The invention relates to a method for improving the quality of fruit and vegetable products, in particular to the use of a compound biological agent in improving the quality of fruit and vegetable products, and the invention belongs to the technical field of agricultural production. Background technique [0002] Strawberry (scientific name: Fragaria × ananassa Duch.), perennial herb, 10-40 cm high. Stems lower than leaves or nearly equal, densely spread yellow pilose. Leaves three out, leaflets with short stalks, thicker in texture, obovate or diamond-shaped, dark green above, almost glabrous, pale green below, sparsely hairy, denser along the veins; petioles are densely covered with yellow pilose. Cymes, with a short-stalked leaflet under the inflorescence; flowers bisexual; sepals ovate, slightly longer than epicalae; petals white, nearly round or obovate-elliptic. The aggregated fruit is large, and the persistent sepals are erect, close to the fru...

Problems solved by technology

[0003] Strawberries generally go on the market in spring. Due to the traditional method of raising seedlings, there will always be some deformed strawberries, strawberries with red and white skins, and strawberries with small particle sizes on the market. These strawberries generally have a low market price and have a bad taste. , many people are not willing to buy, and some strawberries are red and tender in appearance and large in particle size, but they have no sweetness and do not have the unique fragrance of strawberries themselves, which cannot meet the needs of people's taste, which leads to the price of strawberries. However, although some fine varieties of strawberries meet the needs of consumers in terms of taste, color and shape, the high cost of cultivation leads to high market prices, and the economic benefits brought are not obvious
