The invention discloses a fruit swelling composition. Comprising the following raw materials in percentage by mass: 10%-20% of mineral source potassium fulvate, 0.2%-0.7% of bacillus subtilis powder, 0.2%-0.7% of bacillus amyloliquefaciens powder, 8%-14% of urea ammonium nitrate, 8%-14% of monopotassium phosphate, 8%-14% of sugar alcohol calcium, 1%-3% of anhydrous magnesium sulfate, 0.5%-1.5% of ethylenediaminetetraacetic acid ferric sodium salt, 0.5%-1.5% of ethylenediaminetetraacetic acid zinc sodium salt, 0.5%-1.5% of manganese chloride tetrahydrate, 0.5%-1.5% of ammonium molybdate heptahydrate and 45%-50% of water. The fertilizer can maintain the absorption function of a root system, and ensures the water and nutrient supply required by fruit expansion. The mineral source potassium fulvate plays roles in promoting root growth, protecting root and nourishing root by improving the soil structure, coordinating moisture, heat and contradiction of soil and activating soil microorganisms; according to the fruit expanding composition, trace amount is comprehensively supplied, and the fruit expanding efficiency is improved. Fruit cracking can be prevented, calcium and boron participate in forming pericarp cells, the pericarp thickness and toughness can be improved, and fruit cracking caused by pericarp tearing in the rapid fruit expansion process can be avoided through sufficient supply.

This invention belongs to the field of grape cultivation technology, specifically relating to a fruit enlargement agent for Daqing grapes, its preparation method, and its application. The fruit enlargement agent for Daqing grapes is prepared from an aqueous solution of gibberellin, thiabendazole, and brassinolide. Specifically, the concentration of gibberellin in the fruit enlargement agent is 20 mg / L~25 mg / L, the concentration of thiabendazole is 1.0 mg / L~1.25 mg / L, and the concentration of brassinolide is 0.025 μg / L~0.050 μg / L. The fruit enlargement agent of this invention, combined with fruit thinning treatment, can increase the weight of a single Daqing grape berry by at least 20% while retaining the soluble solids content of the grape.

The jujube fruit cracking prevention film agent can prevent jujube fruit cracking.

The utility model relates to the technical field of kumquat planting, in particular to a multifunctional shed for kumquat planting. The multifunctional shed comprises stand columns, supporting columns, side columns, pressing rods, an insect-proof film and a waterproof film, wherein the insect-proof film and the waterproof film cover a shed frame. The insect-proof film effectively prevents insect pests, the waterproof film has a rainproof function, fruit cracking is reduced, and meanwhile the waterproof film can be closed under the high-temperature condition to reduce sunscald; in addition, the shed frame is specially provided with a drainage channel, rainwater drainage is optimized, and the roots are prevented from being waterlogged; the supporting columns are provided with sliding rails and sliding blocks and used for adjusting the coverage area of the waterproof film so as to adapt to different weather conditions. The design of the stand columns considers the stability of the structure and does not interfere with planting and construction operation. The utility model aims to provide a stable and adjustable kumquat planting environment, and aims to improve the environmental conditions of kumquat planting, especially for the variety of crisp and honey kumquats which are susceptible to sunburn and fruit cracking.

The invention provides a processing method of young peaches and a product, and belongs to the technical field of agricultural product processing. The method comprises the following steps: S1, judging a young sheath hardcore; step S2, quick-freezing and storing; s3, spraying alkali and peeling; step S4, enzyme inactivation and green protection; step S5, green-protecting and dipping; step S6, slow freezing treatment; step S7, boiling with sugar for softening; step S8, adding a gum sugar solution; step S9, performing sterilization treatment to obtain a product. According to the method, hard-core young peaches can be removed, the problems of fruit cracking and browning can be avoided through quick-freezing storage, the requirements of concentrated picking and long-time processing are met, the smoothness of the surface of peeled pulp can be guaranteed, meanwhile, the consistency of the color inside and outside the peel in the pulp is maintained, the color is more gorgeous, and the fruit quality is improved. In addition, by adding the gum sugar liquid, the juice of the product can be of a flowing state colloid structure, the edible value is reserved, the taste and the texture are improved, the market value is higher, and the industrial chain is longer.
