Problems solved by technology

[0003] Fragrant pear branch blight and the degradation of pear quality seriously threaten the sustainable development of the fragrant pear industry in Korla. In response to the outbreak of fragrant pear branch blight, the local government has invited experts and scholars from all over the country to investigate the situation of fragrant pear blight. A lot of investigations and experiments have been done on the prevention and control, but no effective technical measures for the prevention and control of fragrant pear branch blight and the quality improvement of fragrant pear have been found so far

Embodiment 1

[0025] The soil conditioner obtained by fermentation was spread into the trench opened next to the pear tree, and watered after covering the soil and applying pressure. The application rate was 400kg per mu. After the soil conditioner was applied, it was combined with spraying biological compound during the critical period of the pear tree disease. fungicide control;

[0026] The preparation method of the soil conditioner includes the following steps: pulverizing Korla pear pear residue and soybean straw respectively, putting them into a mixer for mixing and stirring for 10-20 minutes, adding a certain amount of high molecular polymer, and continuing to stir for 5-10 minutes, The mass ratio of Korla fragrant pear pear residue, soybean straw and high molecular polymer is 4:13:1. After mixing, add a composite starter that accounts for 2% of the total amount of the mixture. The effective number of viable bacteria in the composite starter is ≥2.00×10 8 cfu·g -1 , add water and st...

[0030] The soil conditioner obtained by fermentation was spread into the trench opened next to the pear tree, and watered after covering the soil and applying pressure. The application rate was 400kg per mu. After the soil conditioner was applied, it was combined with spraying biological compound during the critical period of the pear tree disease. fungicide control;

[0031] The preparation method of the soil conditioner includes the following steps: pulverizing Korla pear pear residue and soybean straw respectively, putting them into a mixer for mixing and stirring for 10-20 minutes, adding a certain amount of high molecular polymer, and continuing to stir for 5-10 minutes, The mass ratio of Korla fragrant pear pear residue, corn straw and high molecular polymer is 4:15:1.5. After mixing, a composite starter that accounts for 2% of the total mixture is added, and the effective number of viable bacteria in the composite starter is ≥2.00×10 8 cfu·g -1, add water and stir to a...

Embodiment 3

[0035] The soil conditioner obtained by fermentation is spread into the trench opened next to the pear tree, watered after covering the soil and applying pressure, and the application amount is 300kg per mu. After the soil conditioner is applied, the biological compound fungicide is sprayed on the pear tree; Pear tree disease critical period with spraying biological compound fungicide prevention and control;

[0036] The preparation method of the soil conditioner includes the following steps: pulverizing Korla pear pear residue and soybean straw respectively, putting them into a mixer for mixing and stirring for 10-20 minutes, adding a certain amount of high molecular polymer, and continuing to stir for 5-10 minutes, The mass ratio of Korla fragrant pear pear residue, soybean straw and high molecular polymer is 4:13:1. After mixing, add a composite starter that accounts for 3% of the total amount of the mixture. The effective number of viable bacteria in the composite starter i...

Abstract

The invention relates to a method for preventing and treating the branch blight of Korla fragrant pear. control. Among them, the fermentation raw material of soil conditioner effectively utilizes waste pear residue to synergize fermentation with straw and macromolecular polymer. The beneficial bacteria in soil conditioner can antagonize the pathogenic bacteria of branch blight, effectively inhibiting the growth and spread of pathogenic bacteria in the soil. Fragrant pear residue is rich in polysaccharides and polyphenols, which can promote the growth of beneficial bacteria in the fermentation agent, thereby enhancing the bacteriostatic activity against pathogenic bacteria in the soil. The soil conditioner obtained by the bio-enhanced humification of fragrant pear residue can obtain a healthy microbial ecosystem, and at the same time supplement the soil organic matter content, achieve a significant increase in the number of earthworms in the soil, solve the problems of soil alkalinity and fertility decline, and improve the aroma of the soil. The disease resistance of pear plants, and the purpose of improving the yield and fruit quality of fragrant pears.

Description

technical field [0001] The application relates to the field of agricultural technology, in particular to a method for preventing and treating the branch blight of Korla fragrant pear. Background technique [0002] Korla fragrant pear is a special product of Xinjiang Uygur Autonomous Region and a product of China's National Geographical Indication. Because of its pleasant color, sweet and smooth taste, rich aroma, thin skin and thin meat, crisp and refreshing, juicy and less slag, it can be broken on the ground, melted in the mouth, durable storage, and rich in nutrients. "Prince of Fruit". Since 2016, branch blight began to break out and spread in the Korla fragrant pear plantation, resulting in the phenomenon of dead trees in the whole garden; secondly, the local traditional fragrant pear planting and management technology is backward, and the application of chemical fertilizers and flood irrigation has been used for a long time. Extensive management of fertilizer, water,...
