Embodiment 1
[0035] Bazhou Academy of Agricultural Sciences has carried out the test of adopting the technical scheme of the present invention to prevent and control apple branch blight in some orchards in the Korla fragrant pear production area:
[0036](1) Select fruit trees that are more than 5 years old. During the growth period of the fruit tree, use its trunk as the center to build a waterproof ridge around it that can prevent irrigation water from soaking the trunk. 30cm, for non-dense planting orchards, that is, plant spacing ≧ 2.5m, the waterproof ridge is built as a closed ring-shaped ridge, and the distance between the ridge and the trunk is 30-60cm; for dense planting orchards, that is, the plant spacing is less than 2.5m, waterproof ridges are built as parallel ridges, The distance between the ridge and the trunk is 30-40cm; the distance between the ridge and the trunk increases with the age of the tree;
[0037] (2) Reinforce the waterproof ridge with soil until a permanent r...
Embodiment 2
[0045] In 2017, a serious rot disease broke out in a walnut orchard of a farmer in Wensu County, Aksu, Xinjiang. The walnut orchard was a non-close planted orchard, and the distance between the trees was 5m, all of which were 15-year-old fruit trees. The rot disease prevention and control test was carried out according to the agronomic method of the present invention. .
[0046] (1) Before the winter irrigation after the leaves of the fruit trees fall, build a waterproof ridge around the trunk of the fruit tree in the form of a soil ridge, which can prevent the irrigation water from soaking the trunk. ;The distance between the ridge and the trunk is 50cm;
[0047] (2) Reinforce the waterproof ridge with soil until a permanent ridge is formed to prevent water seepage and collapse; after watering or when the waterproof ridge is damaged, the waterproof ridge should be repaired in time;
[0048] (3) For the area within the waterproof ridge, adopt natural grass and real-time mowin...
Embodiment 3
[0052] In 2018, a serious apple dead branch disease broke out in a farmer's fragrant pear orchard in Korla Awati Farm, Bazhou, Xinjiang. The row spacing of the fragrant pear orchard was 4m × 5 meters, and the tree age was 8 years. Disease control test.
[0053] (1) At the beginning of March 2018, with the trunk of the fruit tree as the center, build a waterproof ridge around it in the form of a soil ridge, which can prevent irrigation water from soaking the trunk. ≧30cm, the inner diameter of the annular waterproof ring is 80cm;
[0054] (2) Reinforce the waterproof ridge with soil until a permanent ridge is formed to prevent water seepage and collapse; after watering or when the waterproof ridge is damaged, the waterproof ridge should be repaired in time;
[0055] (3) For the area within the waterproof ridge, adopt natural grass and real-time mowing method to manage the orchard soil, keep the height of the grass not exceeding 20cm, eliminate perennial weeds, and maintain gro...
