Method for preventing and treating pitaya soft rot disease

Abstract

The invention discloses a method for preventing and treating the pitaya soft rot disease. Before pitaya shoots, a disease-resistant organic fertilizer is scattered; in the overgrowth period of the soft rot disease, a 50% thiram 500-fold solution and a 20% copper abietate wettable powder 600-fold solution are alternately sprayed. According to the pitaya organic fertilizer, photosynthetic bacteria,bacillus subtilis and azotobacter are added, and the organic fertilizer can improve the physical and chemical properties of soil, enhance the soil fertility and assist plants in absorbing nutrients, wherein microelements Fe, Mn, B, Se and Zn can enhance the disease resistance of pitaya, and the fertility of the soil is balanced while the fertility is improved; the soft rot disease prevention effect of the organic fertilizer is improved by 96.13% or above compared with blank control.

Description

technical field

[0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for preventing and treating dragon fruit soft rot. Background technique

[0002] Dragon fruit has very high economic value, and integrates the advantages of fruits, flowers, vegetables and medicine. Its fruit is not only edible, but also has very high nutritional value. It is rich in anthocyanins, plant albumin, Vc and dietary fiber, and has become an excellent green health food. Dragon fruit flower is rich in nutrition, unique in function, contains a large amount of active ingredients, has the effects of improving eyesight, reducing fire, preventing high blood pressure, and has a unique curative effect on cough and asthma. Pitaya flowers can be made into dried vegetables as raw materials for soup or to prepare health functional drinks, and become a health food with both vegetables and teas. At present, dragon fruit is planted on a large scale...

Embodiment 1

[0015] A dragon fruit disease-resistant organic fertilizer, comprising the following raw materials in parts by weight: 50 parts of soybean meal, 50 parts of humic acid, 50 parts of biogas residue, 50 parts of peanut bran, 3 parts of EDTA chelated iron, 3 parts of manganese sulfate, 3 parts of borax, 3 parts of sodium selenate, 3 parts of zinc sulfate, 4 parts of photosynthetic bacteria, 4 parts of Bacillus subtilis, 4 parts of nitrogen-fixing bacteria;

[0016] Weigh the raw materials in the above ratio, mix soybean meal, humic acid, biogas residue, and peanut bran evenly, and then stack and ferment for 10 days. During the first half of the fermentation, turn the pile once every 3 days, add photosynthetic bacteria, Bacillus subtilis, and nitrogen-fixing bacteria. To obtain an organic fertilizer, EDTA chelated iron, manganese sulfate, borax, sodium selenate, and zinc sulfate are uniformly mixed with the organic fertilizer to obtain a dragon fruit disease-resistant organic fertil...
