Enhanced coverage
Use cultivator, hoe and other methods to avoid large amounts of water evaporation in the soil. In the dryland orchards, covering methods such as grass mulching and film mulching are used to preserve the larvae more effectively. At the same time, it is beneficial for the growth of the trees to be robust and the sapling tree growth can be doubled. As a result, the tree yield and quality are improved.
Improved soil
In the case of low soil moisture content, soil improvement should be combined with fertilization in order to gradually increase the soil's ability to retain fertilizer and water. To reduce soil evaporation, soil improvers, soil water retention agents, soil evaporation inhibitors, etc. may be used. In orchards that have not been covered by the ground, the ground should be regularly scratched to make the topsoil fine and loose, preventing the soil moisture from rising to the ground and evaporating. At the same time, rational formula fertilization forms a robust and aging fruit tree constitution. A robust and aging tree body can reduce water transpiration and can store more water. It is recommended to reduce or eliminate spring fertilization.
Timely water saving irrigation
Due to the drought, the groundwater level drops and irrigation water is lacking. In order to ensure the necessary water for the normal growth of fruit trees, it is necessary to germinate and flower the fruit trees in spring. The water-saving irrigation of fruit trees is appropriate. The amount of irrigation water should be 60-70 cm. After long drought, irrigation should be carried out in a small number of times from a few places, so as to prevent mechanical damage to the fruit trees and play an opposite role. In drought-stricken areas where irrigation conditions are not available, “hole storage, fertilizer, and water” can be used to ease the drought. Dig 3 to 5 20-cm-deep pits 10 cm from the root of the tree and pour a bucket of water into each pit. Wheatgrass prevents evaporation, and wheatgrass can be used as an organic fertilizer to feed the tree.
Inter-row grass cultivation
Sorghum cultivation between orchards can reduce the evaporation of soil moisture. The grasses used for cultivation include ryegrass, Bahiagrass, Drosophila, and Ziyunying. Natural weeds can also be used to eradicate high-stem and deep-rooted weeds naturally grown on the ground of the orchard to preserve shallow weeds and dwarf weeds. , such as Huo Xiangxi (stink) and so on.
Reasonable pruning
For Wang Changshu, pruning should be as short and short as possible in order to ease tree vigor and reduce the large amount of water consumed by vegetative growth. For weaker trees, they should be properly retracted so that tree vigor and tree vigor will be strong and the tree's drought resistance will be enhanced. ability. During the growing period of fruit trees, excess sprouts were promptly removed, excess shoots were removed, and thinning and lengthy branches were removed to reduce water transpiration. To minimize the impact of drought on orchards, it is also necessary to grasp from the day-to-day management to increase the “thickness” of the soil, promote deep root systems of fruit trees, and absorb deeper soil moisture.
