Embodiment 1

[0043] Embodiment 1: In 2017, after the severe apple dead branch disease broke out in a large area of ​​farmers' orchards in Korla City, most of the fragrant pear trees died. When replanting, the fragrant pear tending method of the resistance to apple branch dead disease of the present invention was adopted, as follows Implementation:

[0044] (1) Screening of disease-resistant seedlings: Screening of highly disease-resistant Duli pear varieties and cultivating rootstock seedlings as seedlings;

[0045] (2) Excavation of tree planting holes: in the autumn or spring tree planting season, excavate long planting holes in the forward direction on the planned plots;

[0046] (3) Planting seedlings: The prepared seedlings are arranged evenly along the tree-planting hole according to 2-3 seedlings in a hole. The largest sapling is selected as the main seedling and planted in the center of the hole, and the saplings on both sides are auxiliary seedlings close to the two ends of the tr...

Embodiment 2

[0053] Embodiment 2: In 2017, after a large-scale outbreak of serious apple dead branch disease in a farmer's orchard in Yuli County, Xinjiang, most of the fragrant pear trees died. The following steps are implemented:

[0054] (1) Screening of disease-resistant seedlings: screening of highly disease-resistant Du pear varieties and cultivating rootstock seedlings as seedlings; when screening disease-resistant seedlings, breeding Du pear varieties with high resistance to apple branch blight as target seedlings, After 2 years of cultivation, it has reached the national standard first-class Du pear seedling standard;

[0055] (2) Excavation of tree planting holes: During the tree planting season in autumn or spring, excavate long planting holes in the forward direction on the planned plots; the tree planting holes are 60-80cm long, 35-40cm wide, and 40-50cm deep; If the soil is poor or wasteland, increase the planting hole by 20-40% and fill it with an appropriate amount of full...

Embodiment 3

[0063] Embodiment 3: In 2017, after the severe apple dead branch disease broke out in a large area of ​​farmers' orchards in Luntai County, Xinjiang, most of the fragrant pear trees died. The following steps are implemented:

[0064] (1) Screening of disease-resistant seedlings: screening of highly disease-resistant Du pear varieties and cultivating rootstock seedlings as seedlings; when screening disease-resistant seedlings, breeding Du pear varieties with high resistance to apple branch blight as target seedlings, After 2 to 3 years of cultivation, it has reached the national standard first-class Du pear seedling standard;

[0065] (2) Excavation of tree planting holes: During the tree planting season in autumn or spring, excavate long planting holes in the forward direction on the planned plots; the tree planting holes are 60-80cm long, 35-40cm wide, and 40-50cm deep; If the soil is barren or wasteland, increase the planting hole by 30-60% and fill in an appropriate amount...

Abstract

The invention belongs to the field of fragrant pear disease treatment, and particularly relates to a method for tending fragrant pear trees resistant to apple branch blight. The method includes the following steps that (1) disease-resistant seedlings are screened, specifically, high disease-resistant Pyrus betulifolia Bunge variety is screened to cultivate rootstock seedlings; (2) tree planting holes are dug; (3) seedlings are planted; (4) seedlings are shaped; (5) seedling are subjected to bridge joint; (6) fragrant pear scions are selected in an optimizing mode, specifically, the fragrant pear trees with strong tree vigor, complete branches, high fruit setting rate and good fruit shape are selected in an optimizing mode to collect and store the scions, or in a fragrant pear orchard withsevere disease, the fragrant pear trees with no symptoms or mild disease and intact branches and trunks are selected for storage; (7) fragrant pear scions are grafted, specifically, multiple head grafting is carried out according to a method of cultivating seedling pear trees; and (8) management is carried out after grafting. The high disease-resistant Pyrus betulifolia Bunge variety is adopted toplant the fragrant pear rootstock seedlings through one hole with multiple plants, the main and auxiliary seedlings are in bridge joint and grow in an integration mode, the disease-resistant fragrantpear scions are preferred to construct the seedling structure of the fragrant pear trees, and the success rate of tending reaches 80-90%.

Description

technical field [0001] The invention belongs to the field of disease control of fragrant pear trees, in particular to a method for tending fragrant pear trees resistant to apple branch blight. Background technique [0002] Korla Fragrant Pear is a famous and high-quality variety with unique characteristics in Xinjiang, and is well-known at home and abroad. The area of ​​fragrant pears in Korla City as the main production area has grown to 600,000 mu, with an output value of 2 billion yuan, which is an important source of income for 100,000 fruit farmers. In recent years, due to the impact of various natural disasters such as freezing damage, wind disasters, and hail, the output has been unstable and the product quality has declined. Trees died and orchards were destroyed, and the scale of orchards was significantly reduced, resulting in great losses. In order to speed up the restoration and reconstruction of pear orchards and stabilize the industrial scale, it is necessary...
