Sunburn of loquat often occurs. Under what conditions is it easy to happen?

Whether it is effective to water fruit trees with high temperature between small air and full air. Don't say that high storage temperature hurts the roots of fruit trees. Think about it. The plane sprays water from eleven to three. Whether the combustion is reduced. Reduce direct sunlight: Generally, citrus is cultivated in the open air, which can only be reduced by bagging and applying lime. In addition, leaving some branches to keep out the sun during construction can also play a certain role.

Precious fruit trees should be piled up with barbed wire in advance. In case of high temperature and strong sunshine, the sunshade net should be covered in time to reduce the evaporation of water in the orchard, reduce the temperature of the orchard, balance the photosynthesis and respiration of fruit trees, and prevent the sun from directly burning the leaves. In order to prevent soil from hardening and cracking due to continuous high temperature, fruit trees need water to maintain and restore vitality, and water supply and replenishment are particularly necessary. Pumping irrigation can be used, and artificial watering is needed when conditions are insufficient.

To irrigate pear trees in time, the first thing we should do is to ensure that the soil is full of water, so that pear trees can easily absorb water. If conditions permit, sprinkler irrigation can be used to cool the orchard in a timely and moderate manner. In order to prevent sunburn, you can spray 2% lime milk, or increase the amount of lime when spraying Bordeaux liquid, or paint it white; When pruning, leave more auxiliary branches, more inner fruits and less top fruits on the sunny side to avoid direct sunlight on the branches and fruits.

But fruit trees are not called heatstroke, but sunburn, sunburn, sunburn, heat injury and gas burning, all of which are the same. Just like people suffering from heatstroke, they can't resist exposure to high temperature and have symptoms of physiological disorder. Strengthen tree potential and soil management. Organic fertilizer and microbial fertilizer are used as base fertilizers to improve the ability of trees to resist sunburn. In the dry and rainy season in summer, the branches on the back can be kept properly, which can increase the shade, reduce the direct sunlight and reduce the temperature of the tree. The main branch angle should not be too large, and the back should not be exposed. Keep some small branches properly, or twist the leafy branches to cover the big branches to block the direct sunlight.
