When and how to apply fertilizer to kiwifruit?

Kiwifruit is a rattan fruit, originally a wild fruit with strong vitality, but after artificial cultivation, in order to grow well, increase production and high yield, we need to pay attention to fertilization and topdressing. In general, topdressing is based on the growth stage. The method of fertilization should also be adjusted according to the growth status, and the specific situation of fertilization can be analyzed in detail.

1. Base fertilizer

When applying base fertilizer, young trees should apply base fertilizer for the first time before planting. This time, base fertilizer can be widely applied in the whole garden, which is beneficial to absorption and utilization and seedling growth. About 3000 jin of farm manure is applied per mu. If it is planted after a year or an adult fruiting tree, base fertilizer can be applied around November, after fruit harvest and before soil freezing, and it is best to dig trenches to apply fertilizer, which is beneficial to plant absorption and not waste. The base fertilizer is mainly farm manure such as livestock fertilizer, soil fertilizer and straw compost, as well as some quick-acting fertilizer of calcium, magnesium and phosphorus.

2. Topdressing of young trees

Young trees are generally designated after planting, before bearing fruit, it is mainly for growth, the need for fertilizer is relatively much less. In order to continue to grow and provide fertilizer, only a small amount of topdressing is needed. It has been continuously topdressing, mainly applying farm manure and chemical fertilizer. The method of fertilization is circular ditch fertilization or radial fertilization, which is beneficial to root absorption.

3. Topdressing of adult trees

Fertilizer can be applied before flowering and before germination, mainly to promote shoots and shoots, so nitrogen fertilizer is mainly applied. Fertilization in the fruiting period after flower shedding results in the rapid growth of fruit and the need for more fertilizer, which is mainly beneficial to fruit growth and crown growth. In the early stage of fruit ripening, topdressing is needed again in order to ensure the quality and nutrition of the fruit. During this period, foliar fertilizer spraying can also be used to protect flowers and fruits.

4. Fertilization method

For the first time, the basal fertilizer of young trees can be spread throughout the garden, which is beneficial to enrich the soil, improve the soil and apply it before planting. From now on, it will be used in late autumn and early winter, with a large amount of fertilizer, so ditch application can absorb and save labor. The topdressing of young trees should be put into practice, so it is best to apply fertilizer in annular ditches, one by one. For many times, adult trees can be applied by hydrolysis, ring ditch, direct furrow and extra-root topdressing.

Kiwifruit is also a fertilizer-loving plant, general fertilization is very important, different stages, different fertilization standards. You can also choose a more appropriate method of fertilization.
