In the summer, heavy rains often fall, causing disasters in orchards. In this regard, fruit growers should strengthen orchard management from the following aspects.
1. With the exception of sediment storms that cause water in the aftermath of the park, the soil air is occluding oxygen-deficient, and the roots of the fruit trees are severe, which can cause the death of the fruit trees. The sludge should be removed promptly, and the fruit trees should be exposed to the ground 1.5 to 2 cm. For the orchard where the topsoil is washed away, the soil should be mulched as soon as possible. For tilted fruit trees, support can be used to straighten.
2. Timely drainage After the storm, clear the channels immediately, drain the orchard as soon as possible, improve the drainage conditions, and keep the orchard soil dry to restore the ventilation conditions of the fruit tree roots. For orchards that are heavily flooded and cannot be cleared in time in the short term, dug ditches between rows of fruit trees to lower the water level.
3. The tree-blossom wash leaves the fruit trees that have been blown off by the wind and are washed down by the water, and should be straightened in time to remove the debris and sludge from the shoots and foliage. It is best to clean the leaves with a sprayer to ensure the tree body. Normal physiological activity.
4. When cultivating sun soil when the soil is dry, should pay close attention to time cultivator, can increase the depth properly, the soil is mixed, the soil block broken, generally can be 1 to 2 times. For fruit trees that are heavily rooted and rotted, roots should be sown in combination with cultivator eucalyptus and roots should be removed.
5. Reasonable fertilization After the flood, all kinds of orchards can seize the favorable period of good locust and timely fertilizer. Fertilizer types are mainly phosphorus and potassium fertilizers, and rapid fertilization. For heavily orcharded orchards, deeper turning and soil reforms are performed after the lynch is lowered, and then topdressing.
6. Because the tree is pruned to a tree with more dead branches, a fungicide should be sprayed immediately. During the high-temperature period after the flood, we must pay close attention to the occurrence of root rot and root rot in order to prevent and treat the disease.
