A Detailed Guide to the Latest Cultivation Methods for Red-Fleshed Kiwifruit
The most distinctive feature of red-fleshed kiwifruit compared with ordinary kiwifruit is that its flesh is red. Its nutritional value is very high, and its vitamin C content far exceeds that of other fruits, earning it the titles of “vitamin C fruit” and “king of fruits.” Its medicinal value is also gradually being developed, market demand is growing, and its price is quite attractive. The planting area is also becoming larger and larger, so below I will bring you the cultivation methods for red-fleshed kiwifruit. Let's take a look.
1. Site selection and trellis building
A red-fleshed kiwifruit orchard should be chosen in an area with convenient transportation, sufficient water sources, good sun exposure and ventilation, and relatively high humidity. The soil must be loose, rich in nutrients, and highly permeable sandy soil, or mountain land rich in humus. Red-fleshed kiwifruit is mostly supported with flat-topped greenhouse trellises. Existing tree stumps on the mountain land can be used as fixed posts for the trellis, and some artificially made stone posts can be added. Key parts should be reinforced with concrete. The trellis should be 1.5-2 m high, with wire crisscrossing to form a frame for the vines to grow on.
2. Fertilizing and watering
Fertilization should be based on a series of factors such as variety, soil conditions, surrounding weather, and temperature and humidity to determine the amount. When planting, apply an appropriate amount of fruit tree fertilizer into each planting hole. During the young tree stage, fertilization should be frequent and in small amounts. There should be at least three large-scale fertilizations each year. After harvesting in winter, apply base fertilizer, with each plant receiving a mixed fertilizer of 40 jin of organic fertilizer and 3 jin of compound fertilizer. After budding, apply the first topdressing. During the peak growth period, apply the second topdressing. Fruit tree fertilizer or compound fertilizer can be used for topdressing. When fertilizing, be careful not to burn the roots. In dry seasons, remember to water frequently, and do not let red-fleshed kiwifruit lack water and have its growth and development affected.
3. Shaping and fruit thinning
Later shaping of the plants should be carried out according to the previous trellis method, using the trellis surface to distribute the kiwifruit branches evenly. Winter pruning is carried out from after leaf fall in winter to the beginning of budding in early spring. Properly shorten the branches, keep the main vine and the fruiting mother branches, and cut off all the large branches that are too dense, the thin and weak branches with poor growth, and the diseased and pest-damaged branches. Summer pruning is carried out around June, and buds on the main trunk should be removed in time to leave space for the branches and vines. Generally, leave one fruit for every 4-5 leaves, and leave 1-2 fruits about every 20 cm.
4. Disease control
The main diseases of red-fleshed kiwifruit are anthracnose, damping-off, root rot, and many other fungal or bacterial diseases caused by fungi and bacteria. Many diseases not only harm stems and leaves, but also have a great impact on the fruit. Different control measures should be taken for different diseases. For example, to control anthracnose, carbendazim can be sprayed at budding time for prevention. Its main pests include cutworms and scarab beetles. The eggs of these pests and diseases overwinter attached to the soil or diseased plant residues, and harm kiwifruit when they emerge in spring. After harvest, the soil should be disinfected in time and diseased residues should be cleaned up to reduce sources of disease.
The storage time and quality of red-fleshed kiwifruit are closely related to the maturity at the time of harvest. Harvesting the fruit too early or too late will have a great impact on the final quality and taste of the fruit. Therefore, when finally harvesting red-fleshed kiwifruit, be sure to pay attention to the proper harvesting time. A period of storage after harvest will make the kiwifruit more mature and improve the taste. If you want to learn more related information, please continue to follow Qinnong Web!
