[0002] At present, the use of compound fertilizer is a common technical means in the kiwifruit planting process. Compound fertilizer can effectively increase the yield and growth rate of kiwifruit, and can also manage the appearance of kiwifruit. The existing water-soluble fertilizers widely used in kiwifruit planting mostly use water-fertilizer integrated technology or drip irrigation technology. The configuration method of water-soluble fertilizer is single, the application method is relatively single, and the application range is narrow.

[0003] The prior art CN115322027A provides a water-soluble compound fertilizer specifically for kiwifruit and a fertilization method thereof. By applying the fertilizer in a combined stage, it is possible to ensure the yield of kiwifruit and accelerate the growth of kiwifruit, and to ensure the appearance and quality of kiwifruit during the coloring stage, thereby greatly improving the economic benefits of kiwifruit cultivation. The preparation method of the water-soluble fertilizer specifically for kiwifruit is simple and convenient to operate, and can effectively reduce the production cost of the water-soluble fertilizer and reduce the amount of the water-soluble fertilizer used.

[0004] However, in the prior art, kiwifruit is prone to sunburn in summer, which harms the fruit and affects its quality, while existing water-soluble fertilizers cannot effectively prevent sunburn of kiwifruit. Summary of the Invention

[0006] To achieve the above-mentioned object, the present invention adopts a composite high-efficiency disease-preventing water-soluble fertilizer for kiwi fruit, comprising the following raw materials in parts by weight:

[0007] 15-20 parts of nitrogen fertilizer, 18-23 parts of phosphorus fertilizer, 20-25 parts of potassium fertilizer, 10-15 parts of humic acid, 5-9 parts of amino acids, 5-9 parts of nucleotides, 10-12 parts of growth regulators, 7-15 parts of complex trace element chelates, 10-12 parts of water retaining agents, 3-5 parts of garlic powder, 3-5 parts of camphor leaves, 8-10 parts of sulfur powder, 13-15 parts of wood ash, 5-10 parts of fish scale powder, 5-10 parts of shrimp shell powder, 5-10 parts of eggshell powder and 5-10 parts of bone meal.

[0008] The water-retaining agent comprises any one or more combinations of sodium carboxymethyl cellulose, hydroxyethyl cellulose, sodium hexametaphosphate, sodium tripolyphosphate and polyvinyl alcohol.

[0009] The nitrogen fertilizer includes any one or more combinations of urea, ammonium nitrate, ammonium sulfate, ammonium chloride, ammonium bicarbonate and lime nitrogen.

Good soil air permeability and water permeability help the root system of the kiwifruit tree to perform normal respiration, the root system can smoothly absorb oxygen and release carbon dioxide, thereby ensuring the vitality of the root system, and effectively locks the water in the soil, so that the root system can stably absorb water, providing a sufficient water source for the transpiration of the plant, and the transpiration can be adjusted The water balance of the tree can also be maintained, and at the same time, part of the heat of the tree can be taken away by the evaporation of water vapor to prevent the tree from being burned by high temperature. Transpiration maintains the temperature of the leaves and fruits relatively stable, reducing the sunburn caused by excessive temperature. The roots of the kiwi tree will not be damaged by dry soil, and can continue to supply water to the tree, thereby reducing the probability of sunburn. At the same time, locking the moisture in the soil can greatly reduce the temperature of the orchard, thereby reducing water evaporation, thereby extending the watering interval, increasing air humidity, and relatively low surface temperature of fruits and leaves, and sunburn will also be reduced accordingly. The above water-soluble fertilizers can not only increase the sugar content, color and taste of the fruit, but also moisturize and retain water in the soil, effectively avoiding sunburn. Garlic powder, camphor powder and sulfur powder can effectively prevent pests and improve the disease resistance of kiwi. BRIEF DESCRIPTION OF THE DRAWINGS

Good soil aeration and water permeability help the kiwifruit tree root system to carry out normal respiration, and the root system can smoothly absorb oxygen and release carbon dioxide, ensuring the vitality of the root system, and effectively locking the moisture in the soil, which can make the root system It can absorb water stably and provide sufficient water source for the transpiration of the plant. Transpiration can regulate the water balance of the tree. At the same time, it can also take away part of the heat of the tree through the evaporation of water vapor to prevent the tree from being burned by high temperature. Transpiration maintains the temperature of leaves and fruits relatively stable, reducing the sunburn caused by excessive temperature. The root system of kiwi fruit trees will not be damaged by dry soil, and can continuously supply water to the tree, thereby reducing the probability of sunburn. At the same time, locking the moisture in the soil can greatly reduce the temperature of the fruit forest, thereby reducing water evaporation, thereby extending the watering interval, increasing the air humidity, and the surface temperature of fruits and leaves is relatively low, and the sunburn phenomenon will also be reduced accordingly;

[0029] Humic acid can increase soil nutrition, enrich nutrients through adsorption, complexation, chelation, ion exchange and other effects, form a slow-acting nitrogen source, fix nitrogen in the atmosphere, promote the dissolution of insoluble phosphorus and potassium, reduce the loss of nutrients, and promote the dissolution of inorganic components in rocks or minerals, improve soil water holding capacity, regulate soil pH, increase cation exchange capacity, reduce salt content, provide an energy source for soil microbial activity, improve soil microbial populations, and facilitate the growth and reproduction of beneficial bacteria. It can also buffer and reduce the toxicity of soil pollutants.

[0030] Amino acids can be directly absorbed and utilized by kiwifruit trees, providing nitrogen and other nutrients to meet their growth needs, promoting cell division, elongation, and differentiation, helping new shoots grow, leaves unfold and expand, making the fruit bright in color, sweet in taste, and rich in flavor. They can also increase the firmness and storage resistance of the fruit, extending the fruit's shelf life and shelf life.

Good soil aeration and water permeability help the kiwifruit tree roots to carry out normal respiration, and the roots can smoothly absorb oxygen and release carbon dioxide, ensuring the vitality of the roots. Effectively locking the moisture in the soil allows the roots to absorb water stably, providing sufficient water for the plant's transpiration.

Phosphorus fertilizer helps to improve the quality indicators of sugar content and vitamin content of kiwi fruit, making the fruit sweeter and more delicious, and having a better taste. At the same time, it can also increase the color and hardness of the fruit, and improve the appearance quality and storage resistance of the fruit.

[0043] Furthermore, the potash fertilizer includes any one or more combinations of potassium chloride, potassium sulfate, potassium nitrate, potassium dihydrogen phosphate, potassium magnesium sulfate, calcium potassium sulfate, potassium borate and potassium zinc sulfate.
