A Detailed Guide to the Latest Management Essentials for Each Stage of Kiwifruit
Kiwifruit is what we commonly call the kiwi, and it has a large market demand in our country. Kiwifruit is now grown in many parts of our country, and more and more people are planting it. When growing kiwifruit, we need to reasonably adjust management methods according to the growth stage of the kiwifruit. So today, the editor brings you the management essentials for each stage of kiwifruit. Let me briefly introduce them below. Let's take a look together!
1. Management during the bud break stage
Kiwifruit has very poor drought tolerance, so during the bud break stage of kiwifruit we must pay attention to watering frequently to keep the soil moist. Then spread coverings such as weeds and plastic film on the ground to reduce the rate of water evaporation and promote the sprouting of branches and buds. Then do the fertilization work well. Fertilizer during the bud break stage should mainly be high-nitrogen compound fertilizer to promote bud break in the fruit trees and increase yield. The specific amount should be reasonably controlled according to factors such as tree age.
2. Management during the flowering stage
After the kiwifruit trees bloom, we should pinch the tips appropriately. First, when the inflorescence of a fruiting branch has grown about 9 true leaves, pinch the tip. If it is a vegetative branch, then keep 10 leaves before pinching the tip. For excessively vigorous shoots, pinch the tip as early as possible, generally when there are 3 leaves. Then supplement the tree with sufficient nutrients and water to promote pollination and fertilization and increase the fruit-setting rate of the kiwifruit trees. Fertilizer should mainly be compound fertilizer, with a balanced ratio, and the amount applied should likewise be regulated mainly according to tree age.
3. Management during the young fruit stage
During the young fruit stage of kiwifruit, ensure that sufficient nutrients are provided for the growth of the kiwifruit to promote fruit enlargement. Fertilization should mainly use high-nitrogen and high-potassium compound fertilizer, and it should also be quantified according to the age of the planted trees. Moreover, during the young fruit stage, kiwifruit has the greatest demand for magnesium, so at this time magnesium foliar fertilizer should be sprayed appropriately. Then do the work of removing buds and thinning branches well to prevent excessive nutrient consumption, improve the air and light penetration of the tree, and appropriately pinch tips and thin fruit.
4. Management during the fruit-strengthening stage
During the fruit-strengthening stage, the fruit grows faster, so during this period the tip-pinching work should still be done well, and the tender buds at the very front of long shoots should be removed. Avoid the phenomenon of branches and shoots turning leaves and curling during growth. Fertilization should mainly use high-potassium compound fertilizer, and then appropriately apply additional foliar fertilizers such as potassium dihydrogen phosphate. Do the weeding work well, regulate the soil temperature, improve the soil's water- and fertilizer-retention capacity, control the number of leaves well, and avoid leaves competing with fruit growth for nutrients and water.
5. Management during the expansion stage
After kiwifruit enters the fruit expansion stage, pay attention to supplementing trace elements. For example, spraying calcium fertilizer and so on can enhance the hardness of the fruit and reduce mechanical damage. Then pick the fruit on sunny days with no rain, and after picking the fruit do the orchard cleaning work well. Carry out one intertillage of the soil, and then do one round of pruning and vine tying in winter to encourage the fruiting mother branches to retract as much as possible near the main branches and vines, so that the wounds can heal as quickly as possible.
The above is a brief introduction to the management essentials for each stage of kiwifruit. The management work for kiwifruit is very important, and management methods must be reasonably adjusted as the growth period of the kiwifruit changes. That is all for today's introduction.
