Fertilization time of kiwifruit

Kiwifruit, also known as kiwifruit, is a kind of fruit with great market demand. In China, the planting area is relatively large, when planting kiwifruit, whether it is family planting or large-scale planting. Fertilization is very important. Fertilization also includes base fertilizer and topdressing. Good fertilization is the key to ensure the high yield of kiwifruit. So when should kiwifruit be fertilized? The following editor brings you the fertilization time of kiwifruit, let's have a look!

1. The time of applying base fertilizer

The basic fertilizer of kiwifruit should be carried out in autumn, and early application after harvest is beneficial to the growth and development of kiwifruit trees. The fertilization time is about October to November, because during this period, the nutrients synthesized by kiwifruit leaves will gradually return to the roots. To promote the formation of roots, the tree will once again enter the peak period of growth. And because of the lack of fruit water regulation in leaves after fruit harvest. There will be a short-term decline in function, so there is an urgent need for fertilizer and water to promote the restoration of leaf function.

After the application of base fertilizer, it is necessary to cooperate with irrigation work properly, which can play an important role in the functional recovery and maintenance of leaves. It can also delay the senescence of leaves and improve the life of leaves. Prolong the photosynthesis time of leaves. Applying sufficient base fertilizer in autumn can improve the nutrition accumulation of kiwifruit trees. It is very beneficial to the flower bud differentiation after defoliation and the second year. It can promote the germination of buds and shoots, improve the quality of flowers and the rate of pollination and fruit setting. The base fertilizer should be based on organic fertilizer, combined with an appropriate amount of available nitrogen fertilizer, and phosphorus and potassium fertilizer can be added according to the actual situation. The amount of fertilizer should be kept at about 3 per cent of the amount of fertilizer applied throughout the year.

2. Topdressing time

1. Sprout fertilizer

In the growth period of kiwifruit throughout the year, the frequency of topdressing should be kept at least twice. For the first time in February and March of every spring, kiwifruit trees apply sprouting fertilizer before and after sprouting. Because this is the time when the axillary buds sprout and the branches and leaves grow. Rational fertilization is beneficial to promote the two work of trees, so as to improve the fruit setting rate of kiwifruit trees. Topdressing fertilizer is mainly available nitrogen fertilizer, and then combined with appropriate amount of potash fertilizer,

2. Strong fruit and promote shoot fertilizer

Then around July in summer, after falling flowers, the tree applied a strong fruit to promote shoot fertilizer. This is the period of rapid expansion of young fruit, whether the growth of summer shoots or flower bud differentiation need to consume a lot of nutrients. Therefore, we can according to the growth of kiwifruit trees, reasonable topdressing about twice. During this period, topdressing fertilizer should be based on the combined application of nitrogen, phosphorus and potassium fertilizer, and the growth of kiwifruit trees should be observed. if there is a deficiency, then corresponding adjustments should be made in time.

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