When is the fertilization time for kiwifruit?

Kiwifruit is also called kiwi, and it is a fruit with relatively large market demand. Its planting area in our country is relatively large. When planting kiwifruit, whether for home planting or large-scale planting, fertilization work is very important. Fertilization includes base fertilizer and topdressing. Doing a good job in fertilization is the key to ensuring high yield of kiwifruit. So when should kiwifruit be fertilized? Below, the editor brings you the fertilization time for kiwifruit. Let's take a look!

1. Time for applying base fertilizer

The base fertilizer for kiwifruit should generally be applied in autumn. Applying it appropriately early after harvest is relatively beneficial to the growth and development of kiwifruit trees. The fertilization time is around October to November, because during this period, the nutrients synthesized by the leaves of kiwifruit trees will gradually return to the root system. This promotes root formation, and the tree body will once again enter a growth peak period. Also, because after the fruit is harvested, the leaves lack the water regulation provided by the fruit. There will be a short-term decline in function, so fertilizer and water are urgently needed to promote the recovery of leaf function.

After the base fertilizer is applied, it should be properly combined with irrigation work, which can play a relatively large role in restoring and maintaining leaf function. It can also delay leaf aging, improve leaf lifespan, and prolong the photosynthesis time of leaves. Applying sufficient base fertilizer in autumn can improve the nutrient accumulation of kiwifruit trees. It is very beneficial to the tree body after leaf fall and to flower bud differentiation in the second year. It can promote sprouting and the emergence of new shoots, and improve flower quality and the pollination and fruit-setting rate. The base fertilizer should be mainly organic fertilizer, combined with an appropriate amount of quick-acting nitrogen fertilizer. According to actual conditions, phosphorus and potassium fertilizer can also be added. The amount used should remain at about 3/5 of the annual fertilization amount.

2. Topdressing time

1. Sprouting fertilizer

During the annual growth period of kiwifruit, the number of topdressings should be kept at at least two or more. The first is in February to March each spring, before and after kiwifruit trees sprout, applying sprouting fertilizer once. Because this time is the period for axillary bud germination and branch and leaf growth of the tree body. Reasonable fertilization is conducive to promoting these two processes in the tree body, thereby increasing the fruit-setting rate of kiwifruit trees. The topdressing fertilizer should be mainly quick-acting nitrogen fertilizer, then combined with an appropriate amount of potassium fertilizer.

2. Fruit-strengthening and shoot-promoting fertilizer

Then around July in summer, after the tree body flowers fall, apply fruit-strengthening and shoot-promoting fertilizer once. This time is the period when young fruit rapidly expands. Whether it is the growth of summer shoots or flower bud differentiation, both need to consume a large amount of nutrients. Therefore, we can reasonably apply topdressing about twice according to the growth vigor of kiwifruit trees. The topdressing fertilizer in this period should be mainly combined application of nitrogen, phosphorus, and potassium fertilizers. Observe the growth of kiwifruit trees. If there are deficiency symptoms, then timely corresponding adjustments should be made.

The above is a brief introduction to the fertilization time for kiwifruit. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
