Detailed Explanation of Key Technical Points for Kiwifruit Field Management

Kiwifruit is what we have come to know as the very popular kiwi in recent years. Kiwifruit can be grown in most regions of our country, and the yields are quite good. One of the main reasons for this is related to its field management, as the methods of field management differ to some extent at different time periods. Below are some kiwifruit field management methods compiled by Qinnongwang for everyone's reference.

Spring Management

The first task of spring field management is to prevent late frost damage. You must always pay attention to weather changes and then paint the tree trunks white. If you were unable to prepare in advance and damage has already occurred, spray Sea Elf biological stimulant foliar type and brassinolide to alleviate the frost damage symptoms. Next, in early spring, kiwifruit needs branch and leaf pruning. Remove the aged vines and then gently wipe off the buds on the main vine, which can promote new branch growth. Finally comes watering and fertilizing. First, dig ring-shaped trenches near the plants, then evenly scatter fertilizer into the trenches and cover with soil, and finally water around the fertilized area.

Summer Management

Summer is typically characterized by high temperatures and abundant rain, but it is also when kiwifruit blooms and sets fruit, so management during this period is very important. The most important thing during this time is topdressing. We should apply fertilizer according to the plant's growth conditions. If the plant is weak in growth and somewhat yellow, then we can apply a certain amount of urea. Apply fertilizer once ten days before flowering, apply a second time half a month after flowering, and apply a third time after the kiwifruit has set fruit. Usually, potassium fertilizer and phosphorus fertilizer are the main types used. Next, when temperatures are high, we water once in the morning and once in the evening, which can help dissipate heat. When there is a lot of rain, trenches should be opened promptly for drainage.

Autumn Management

Kiwifruit generally begins to ripen from the end of August and continues until the end of October. During this ripening period, if summer management was done properly, there are basically no problems. After the kiwifruit harvest is complete, which is in November, we should begin tilling the soil and applying base fertilizer. When tilling, you should dig at least about 60 cm deep, and every kiwifruit seedling must be covered. Fertilization is mainly based on organic fertilizer, which can be used in combination with nitrogen fertilizer, phosphorus fertilizer, and compound fertilizer. The fertilization method is still trenching or ring-shaped trenching.

Winter Management

Kiwifruit has extremely strong cold resistance, but frost damage can sometimes still occur. So to be safe, warmth protection is still needed in winter. We can enhance the plant's resistance by increasing the application of organic fertilizer. Next is establishing windbreak belts and mounding soil to protect the trunks. At the same time, some straw can be piled around the original area, which can also have an insulating effect. Next, winter requires branch and leaf pruning, mainly to regulate the relationship between kiwifruit growth and fruiting, so that it grows in a fixed direction the following year. At the same time, some diseased branches and old branches can be cut off, which can make the kiwifruit yield better the following year. Since it is winter pruning, after pruning you must treat with chemicals, otherwise there will be bacterial infection, causing the plant to rot.
