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] Sprinkle the fermented soil improver in the ditch next to the pear tree, cover the soil and apply pressure, and then water. The application rate is 400kg per mu. After applying the soil improver, spray the biological compound in the critical period of pear tree disease. fungicide control;

[0026] The preparation method of the soil improver comprises the following steps: respectively pulverizing Korla fragrant pear dregs and soybean stalks, 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 dregs, soybean straw and high molecular polymer is 4:13:1. After mixing, add a compound starter that accounts for 2% of the total amount of the mixture. The effective number of viable bacteria in the compound starter is ≥2.00×10 8 cfu·g -1 , add water and stir until semi-dry and semi-wet state, water content 35%, to obtain fermentation r...

Abstract

The invention relates to a method for preventing and controlling branch blight of Korla fragrant pears, which comprises the following steps: spreading a soil conditioner obtained by fermentation into grooves formed beside pear trees, performing earthing and watering, and spraying a biological compound bactericide in a key period of morbidity of the pear trees in a matched manner for prevention and control. The fermentation raw materials of the soil conditioner effectively utilize waste pear residues, straw and the high-molecular polymer for synergistic fermentation, beneficial bacteria in the soil conditioner can generate antagonism with pathogenic bacteria of the branch blight, and growth and propagation of the pathogenic bacteria in the soil are effectively inhibited. The fragrant pear residues are rich in polysaccharides and polyphenols, and can promote the growth of beneficial bacteria in the fermentation inoculant, thereby enhancing the antibacterial activity of pathogenic bacteria in soil. The soil conditioner is obtained through biologically-enhanced humification of the fragrant pear residues, a healthy microbial ecological system is obtained, meanwhile, the content of organic matter in soil is supplemented, the number of earthworms in the soil is remarkably increased, the problems of soil alkalization and fertility decline are solved, and the purposes of improving the disease resistance of fragrant pear plants and improving the yield and fruit quality of fragrant pears are achieved.

Description

technical field [0001] The application relates to the field of agricultural technology, in particular to a method for preventing and treating 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 pleasing color, sweet and smooth taste, strong aroma, thin skin and fine meat, crisp and refreshing, juicy and less slag, it breaks when it falls to the ground, melts in the mouth, durable storage, and rich in nutrition. It is known as the "treasure among pears", "The Prince of Fruits". Since 2016, branch blight began to break out and spread in the Korla fragrant pear plantation, causing the phenomenon of dead trees in the whole garden; secondly, the local traditional fragrant pear planting and management technology is backward, and the long-term use of chemical fertilizers is the main method, flood irrigation , Extens...
