The Latest High-Yield Fertilization Methods for Red-Fleshed Kiwifruit

The market for red-fleshed kiwifruit is growing larger and larger now, and many friends have been drawn in by its profits and have started planting it on a large scale. The final yield of kiwifruit determines the farmers' ultimate economic benefit. So many friends want to achieve high-yield, high-volume results, but they don't know how to go about it. In fact, yield and fertilization are closely related; as long as fertilization management is done well, achieving high yield is not very difficult. Now let's take a look together with the editor at the high-yield fertilization techniques for red-fleshed kiwifruit!

1. Bud-Promoting Fertilizer

Bud-promoting fertilizer is indispensable. It can generally be applied as a top dressing in early spring, once spring temperatures rise, the soil thaws and softens, and the sap in the tree begins to flow and activity starts. Then you can begin applying the bud-promoting fertilizer, because spring is the season when all things revive. After experiencing the winter season of nutrient shortage, the tree certainly needs a large amount of nutrients to replenish its reserves. Applying bud-promoting fertilizer at this time is best of all; it not only replenishes sufficient nutrients for the tree but also promotes sprouting and flowering. Bud-promoting fertilizer is mainly composed of quick-acting nitrogen fertilizer with a small amount of phosphorus and potassium fertilizer.

2. Fruit-Promoting Fertilizer

Fruit-promoting fertilizer is mainly used to promote the growth and expansion of the fruit. About one month after fruit set and flower drop comes the most critical period for kiwifruit —— the rapid fruit expansion period. The expansion period is especially important for kiwifruit, because at this stage the fruit grows at its fastest rate, growth speeds up, and volume increases rapidly. If fertilizer is lacking at this time, expansion will be blocked. The fruit cannot expand, and the final harvest is seriously affected in quality and commercial value. So you must ensure the application of fruit-promoting fertilizer, mainly quick-acting compound fertilizer, followed by watering the entire orchard after application.

3. Fruit-Strengthening Fertilizer

Fruit-strengthening fertilizer is applied as a top dressing in midsummer. It is best to apply an appropriate amount of phosphorus and potassium fertilizer to each tree around June, with the aim of compensating for insufficient nutrition in the later period that would affect the growth of branches and shoots. Alternatively, you can spray quick-acting nitrogen fertilizer on the leaves once or twice. Spraying calcium fertilizer during this period can also improve the storage time of the fruit after harvest; mainly, foliar fertilizer is sprayed. Foliar fertilizer has a great influence on the final harvest. This is because at this stage the branches and shoots lack nutrition, which affects growth and development and also causes certain harm to the fruit.

4. Wintering Fertilizer

Wintering fertilizer is the base fertilizer. After the winter harvest is complete, cultivate and earth up the soil, disinfect the orchard, clear away diseased and damaged branches, and apply base fertilizer. This is mainly to prevent bacteria, insect eggs, and other pests and diseases from attaching to them and overwintering. Wintering fertilizer is mainly composed of fully decomposed farmyard manure, which can be mixed with an appropriate amount of calcium phosphate and other fertilizers. After the base fertilizer is applied, let it ferment and generate high temperature to kill bacteria and insect eggs in the orchard, preparing for the next year's sprouting and preventing pathogens from harming the tree in early spring.

The above four fertilizers are the most important fertilizers for red-fleshed kiwifruit during the four key stages of cultivation. The most important are still the fruit-promoting fertilizer and the wintering fertilizer. The fruit-promoting fertilizer is the best aid for promoting fruit expansion, and successful fruit expansion is extremely beneficial for later growth. It can also greatly improve the final quality. The wintering fertilizer prepares for the second year, reduces the incidence of disease, and improves the survival rate of the fruit trees. I hope this article can be of some help to everyone.
