Detailed Explanation of Management Key Points for Each Growth Stage of Kiwifruit
Kiwifruit is what we commonly call the kiwi, and it has a large market demand in China. Kiwifruit is now distributed in many places across China, and more and more people are growing it. When growing kiwifruit, we must reasonably adjust management methods according to the growth stages of kiwifruit. So today, the editor brings you the management key points for each stage of kiwifruit. Let me briefly introduce them below. Let's take a look together!
1. Management During the Budding Stage
Kiwifruit has very poor drought tolerance, so during the budding 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 a good job with fertilization. Fertilizer during the budding stage should mainly be high-nitrogen compound fertilizer to promote sprouting of 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 appropriately pinch off the growing tips. First, when the inflorescence on the fruiting branch has grown about 9 true leaves, pinch off the growing tip. If it is a vegetative branch, then keep 10 leaves before pinching. For vigorous water shoots, pinch 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, it is necessary to ensure sufficient nutrients are provided for the growth of kiwifruit to promote fruit enlargement. Fertilizer application should mainly be 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 appropriately sprayed. Then it is necessary to do a good job of bud removal and branch thinning to prevent excessive nutrient consumption, improve the permeability of the tree canopy, and appropriately pinch growing tips and thin fruit.
4. Management During the Fruit-Strengthening Stage
During the fruit-strengthening stage, the fruit grows faster, so pinching of growing tips should still be done well during this period, and the tender buds at the very front of long shoots should be removed. Avoid the phenomenon of leaves turning over and curling at the branch tips. Fertilizer application should mainly be high-potassium compound fertilizer, and then appropriately apply additional foliar fertilizers such as potassium dihydrogen phosphate. Do a good job of weeding, regulate the soil temperature well, 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, attention should be paid to supplementing trace elements. For example, spraying calcium fertilizer can enhance fruit firmness and reduce mechanical damage. Then harvest on sunny days with no rain, and after harvesting, do a good job of clearing the orchard. Carry out one intertillage of the soil, then carry out one pruning and vine-tying operation in winter to encourage the fruiting mother branches to retract as close as possible to the main branches and vines so that the wounds can heal as quickly as possible.
The above is a brief introduction to the management key points 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 kiwifruit changes. That is all for today's introduction.
