When is the right time to irrigate kiwifruit in winter?

Kiwifruit will gradually enter the dormant period in winter, and the tree will not have a great demand for nutrition. Therefore, the winter fertilization work can be relaxed a little bit, but we should pay attention to the winter irrigation work. Reasonable winter irrigation can effectively help kiwifruit trees survive the winter safely and ensure their production capacity in the second year. So when is the right time for kiwifruit trees to be irrigated in winter? How to irrigate in winter? The following editor will give you a brief introduction, let's have a look!

1. Winter irrigation time

When we irrigate kiwifruit in winter, we must first judge the appropriate time for winter irrigation. Generally speaking, it should be carried out during the period from kiwifruit harvest to soil freezing. However, it is best to carry out when the average temperature of the soil layer is about 5 degrees, when the effect of winter irrigation is the best. However, before winter irrigation, we should also pay attention to whether rhesus monkeys and peach trees need water. Generally speaking, the maximum field water holding capacity of planting kiwifruit trees is about 70%. After entering the dormant period, the water holding capacity should be increased by about 10% to ensure that kiwifruit trees survive the winter safely, so if the soil water holding capacity is insufficient, it should be irrigated in winter in time.

II. Winter irrigation methods

1. Well irrigation

Well irrigation is a main method of winter irrigation for kiwifruit trees. However, the first condition is to have a well, and for qualified fruit growers, well irrigation can be carried out. Before winter irrigation, the canal should be dug between the rows of kiwifruit trees according to the row spacing of fruit trees. Then put the water into the canal and irrigate the soil to make the fruit trees absorb sufficient water, increase the water content of the roots and ensure that the fruit trees survive the winter safely.

2. Watering roots

In winter irrigation, the irrigation method will be different according to the age of the tree. For example, it is necessary to irrigate the roots of two-year-old kiwifruit trees during winter irrigation. First of all, the rhesus monkey tree should be built into a ridge around the tree plate with soil. The height of the ridge should be kept around 18cm to avoid overflowing during watering and to prevent waste of water resources. Concentrate water and promote water to permeate as soon as possible.

3. Trench

For perennial fruit trees, a small ditch should be dug around the 60cm of the fruit trees. Then pour the water into the ditch and let the water slowly seep into the roots, prompting the roots to absorb. If it is not watered thoroughly the first time, it will be watered again the next day. Then fill the ditch with soil to avoid frostbite caused by air leakage. When digging ditches and filling soil, we should also be careful not to hurt the roots, otherwise it will have a great impact on the growth of fruit trees.

4. Turn the land to preserve soil moisture

Winter irrigation can easily lead to soil surface hardening, soil consolidation will accelerate water evaporation, thus reducing the effect of winter irrigation. Therefore, when we irrigate in winter, we should turn the land reasonably according to the soil type of the orchard. Destroy the soil capillary system and reduce soil water evaporation. Then sunburn in winter to improve soil fertility, but also can reduce the number of diseases and insect pests, reduce the incidence.

The above is a brief introduction to the appropriate time for winter irrigation of kiwifruit. That's all for today's introduction. This article is for reference only. I hope it can help you all.
