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...

Abstract

The invention belongs to the field of fruit tree disease prevention, and relates to an agronomic method for preventing infectious diseases of fruit trees, which comprises the following steps: (1) fruit trees of more than 5 years old are selected, waterproof ridges capable of preventing irrigation water from soaking a trunk around the trunk are constructed, the distances between the ridges and thetrunks are increased along with the increase of tree age, for a non-close planting orchard, the waterproof ridges are closed annular ridges, and for a close planting orchard, the waterproof ridges areparallel ridges; (2) the waterproof ridges are reinforced to form permanent ridges to prevent water seepage and collapse; hilling is carried out in time when watering is carried out or waterproof ridges are damaged; and (3) for an area within the waterproof ridges, orchard soil management is carried out by adopting a natural grass growing and real-time mowing method, the grass growing height is kept to be not greater than 20 cm, perennial weeds are killed, and ground vegetation with annual plant species as the main species is kept; for areas outside the waterproof ridges, an organic fertilizer is applied in the spring and autumn, and mechanical soil plowing is carried out. The method can effectively prevent pathogenic bacteria of central diseased plants from diffusing and spreading, and is high in operability, simple, practical, free of investment and remarkable in effect.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of fruit tree diseases and insect pests, in particular to an agronomic method for preventing infectious diseases of fruit trees. Background technique [0002] The main method of irrigation for fruit trees in the north is flood irrigation, relying on external water sources to supplement soil moisture to meet the basic needs of fruit tree growth. In inland arid areas such as Northwest China, the precipitation is low, the climate is dry, the sunlight is strong, the soil evaporation is large, and the average relative humidity of the orchard is 30% to 40%. Over the past two decades, the phenomenon of excessive groundwater production has been common, leading to a rapid decline in groundwater levels. Irrigation of orchards is particularly water demanding. Due to the drought and water shortage, the contradiction of water use is particularly prominent. Problems such as irrigation on time an...
