When to Fertilize Kiwi Fruit? Detailed Guide to Fertilization Methods
Kiwi fruit is a vine fruit, originally a wild fruit with strong vitality, but after artificial cultivation, in order to grow well, increase yield and achieve high yield, attention must be paid to fertilization and topdressing during cultivation. Generally, topdressing is applied according to the growth stage. The fertilization method should also be adjusted according to the growth condition; the specific fertilization situation can be analyzed in detail.
1. Base fertilizer
For base fertilizer application, for young trees, the first base fertilizer should be applied before planting. This base fertilizer can be broadcast over the whole orchard, which is beneficial for absorption and utilization and for seedling growth. About 3000 jin of farmyard manure is applied per mu. If it is one year after planting or a mature fruiting tree, base fertilizer can be applied around November, after fruit harvest and before the soil freezes. It is best to apply the fertilizer by digging trenches, which is beneficial for plant absorption and avoids waste. The base fertilizer is mainly farmyard manure such as livestock manure, soil and miscellaneous manure, and straw compost, as well as some quick-acting fertilizers such as calcium magnesium phosphate.
2. Topdressing for young trees
⟦NL>Young trees generally refer to the period after planting and before fruiting. At this time, the main purpose is growth, and the fertilizer requirement is relatively much smaller. In order to supply fertilizer for continuous growth, only a small amount of topdressing needs to be applied multiple times. Continuous topdressing is mainly farmyard manure and chemical fertilizer. The fertilization methods are ring-shaped trench fertilization or radial fertilization, both of which are beneficial for root absorption.
3. Topdressing for mature trees
Before flowering and before sprouting, fertilizer can be applied, mainly to promote branch and shoot growth, so nitrogen fertilizer is mainly applied. After the flowers fade, fertilizer is applied during the fruiting period. The fruit grows quickly and the fertilizer requirement increases, which is mainly beneficial for fruit growth and canopy expansion. In the early stage of fruit ripening, topdressing is needed once more to ensure fruit quality and ensure nutrition. During this period, foliar spraying can also be used to protect flowers and fruits.
4. Fertilization methods
For the first base fertilizer for young trees, it can be broadcast over the whole orchard, which is beneficial for enriching the soil and improving the soil, and is applied before planting. After that, it is used in late autumn and early winter. Because the fertilization amount is large, trench application is used, which can be absorbed and saves labor. Topdressing for young trees should be carried out effectively, so ring-shaped trench fertilization is best, carried out tree by tree. For multiple topdressings for mature trees, water-soluble application can be used, or ring-shaped trench application, or direct row trench application, and root-outside topdressing can also be used.
Kiwi fruit is also a fertilizer-loving plant, so fertilization is generally very important, with different fertilization standards at different stages. A more suitable fertilization method can also be chosen.
