Application skills and precautions of water-soluble fertilizer
Water soluble fertilizer refers to water-soluble compound fertilizer, including solid and liquid forms. Generally speaking, the formula of water-soluble compound fertilizer is more reasonable, the nutrients are more diversified, and it is more targeted to crops. However, unreasonable use in production will cause waste of fertilizer and even play a negative role. Fertilization requirements: small amount and multiple application is an important fertilization principle of water-soluble fertilizer, which is in line with the characteristics of continuous nutrient absorption by plant roots and reduces the leaching loss caused by one-time massive fertilization. A small amount of repeated application is an important reason for the high utilization rate of water-soluble fertilizer. Generally, the dosage per mu is 3 ~ 6 kg each time. There are few seedling stages and more vigorous growth stages.

How to fertilize kiwifruit, fertilization technology
(1) The soil begins to thaw in spring. After the sap flows, the tree begins to move. Fertilization at this stage is conducive to germination and flowering, and promote the growth of new buds. High nitrogen fertilizer and a small amount of phosphorus and potassium fertilizer should be applied before germination. For example, 30-10-10 and potassium dihydrogen 0-52-34. (2) During the growth period, balanced fertilizer 20-20-20 is used for balanced absorption and growth. (3) At flowering stage, high phosphorus 12-50-7 was used to promote flower bud differentiation, protect flowers and promote fruit. (4) It is suggested to use potassium to transport the world 13.5-0-46 and high potassium water-soluble fertilizer 14-6-40 in the early fruit stage. Observe the fruit growth and pay attention to it. Prevent flower falling, fruit falling, fruit cracking, frozen fruit and abnormal fruit.
