Orchard Management of Kiwifruit in Summer

July-August is the hottest period of the year, and it is also the second period of fruit expansion and quality formation of kiwifruit, which is the most important period for the growth and nutrition accumulation of kiwifruit. However, with the high temperature and rain in summer, the management of orchards is becoming more and more important. If you don't pay attention to it, it is easy to cause diseases and insect pests and heat damage. So how to manage the orchard correctly is very important. Let's take a look at it.

1. Prevent burns

High temperature can easily burn kiwifruit. When it comes to the hottest time, the most important thing is to prevent kiwifruit from being burned by direct sunlight. Before this time comes, plant some raw grass in the orchard, which can well reduce the temperature in the orchard. Some experiments have shown that the temperature in the orchard without grass can reach more than 40 degrees, and the temperature in the orchard with grass can be reduced by at least eight degrees. So growing grass is very effective in preventing burns. Do not remove all the old leaves from the fruit, because the old leaves can protect the fruit from the sun and reduce the intensity of direct sunlight.

2. Fertilizer and water management

July is the time when kiwifruit needs water and fertilizer most, and it is also an important period for the accumulation of dry matter within the fruit, and it is a critical time for the growth and development of kiwifruit trees. The second expansion and new shoot growth all need a lot of water and fertilizer, so it is necessary to ensure the amount of fertilizer and water in the orchard in summer. The most important fertilizer is excellent fruit fertilizer, which is the last fertilization before harvest, but the amount of nitrogen fertilizer should be controlled mainly by phosphorus and potassium fertilizer. And summer will make the orchard very easy to drought, at this time should pay attention to the orchard watering and irrigation, lack of water will make the fruit dry, serious lack of water, but the soil should not be stagnant water, stagnant water will lead to soil hypoxia, affecting root respiration.

3. Shelf management

At this time, the new shoots that can not be picked up in the early stage should be thinned and cut slightly to avoid the excessive growth of the new shoots upward. The cross-growing branches and malnourished branches as well as some disease and insect tips were cut off. The overgrown branches on the main side of the vine should be cut in time to inhibit their growth, but pay attention to the number of buds left, and those that are not left should be wiped immediately to avoid affecting the thickening growth of grafted branches. The main reason is that the probability of heat damage will be increased, and the leaves growing in the inner layer will be removed to avoid competing for nutrients with other normal growing leaves and fruits.

4. Prevention and control of diseases

The main diseases of kiwifruit are anthracnose, brown spot and other bacterial diseases, the best way is to prevent in advance and do a good job of shelf management. To ensure the permeability of the shelf surface, it is necessary to carry out a rotation of drugs in orchards that are more prone to disease, so as to control the incidence of diseases. Summer is also the active season for many pests, such as beetles. The most important way to prevent pests is to reduce the number of adults. Reduce the number of eggs to reduce the number of adults in the coming year, you can use light traps and other means to kill adults.

These are the management matters that kiwifruit need to pay attention to in summer. Burns are very common. Last year, kiwifruit disasters were caused by high temperature and drought. It is necessary to reduce the sun's direct exposure to kiwifruit and water them frequently to keep the trees moist. Diseases and insect pests are also a very troublesome problem. Take preventive measures to minimize the incidence of all diseases.
