A cultivation method for preventing and repairing citrus yellowing disease

Abstract

The invention relates to a culturing method for preventing and repairing citrus yellows. The method comprises the following steps: planting, cutting lateral roots, managing fertilization, remaining fruit quantitatively, and constructing a drainage and irrigation system, wherein the step of cutting the lateral roots is that a strip-shaped ditch is dug between plants or rows for cutting the lateral roots after the blossoms of citrus fell, and a root repair agent is sprayed and applied immediately after the lateral roots are cut; the step of managing the fertilization comprises fertilizing a post-blossom falling fertilizer heavily, spraying a leaf fertilizer, and applying an organic liquid fertilizer at a root, wherein the step of fertilizing the post-blossom falling fertilizer heavily is that 16 to 32 kilograms of self-made fertilizer is applied to each plant by combining deep plowing and soil improving after the lateral roots are cut; orchard wedding is combined when the fertilizer is applied, weeds, the fertilizer and soil are fully and uniformly mixed and then are backfilled into the strip-shaped ditch. The culturing method for preventing and repairing the citrus yellows provided by the invention has the advantages of simple method, high operability, good effects on preventing and repairing the citrus yellows and the like.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cultivation method for preventing and repairing citrus yellowing disease. Background technique [0002] Citrus fruit is rich in nutrition, full of color, fragrance and taste. It can be eaten fresh, and can be processed into beverages such as fruit juice, fruit wine, fruit vinegar, etc., and orange peel essential oil can also be extracted. The nutritional value of citrus is very high, its protein content is 9 times that of pears, the content of calcium is 5 times that of pears, the content of phosphorus is 5.5 times that of pears, the content of vitamin B1 is 8 times that of pears, and the content of vitamin B2 is 8 times that of pears. 3 times, the content of vitamin C is 10 times that of pears, in addition, citrus also contains a variety of vitamins and elements such as potassium, magnesium, sulfur, sodium, chlorine and silicon. With high and stable yiel...

Problems solved by technology

When the soil is too acidic, that is, when the pH value is lower than 4.5, the absorption and utilization rate of almost all nutrient elements by the root system is reduced by 60-80%, and the residual substances accumulated in the acidified soil react with the elements in the fertilizer to form a film body , during the long-term absorption of nutrients by the roots, the film body is brought into the tree sieve conduit to form accumulation, causing transportation blockage, and on the other hand, the roots also form root wrapping due to long-term absorption of the film body accumulated around them, resulting in lack of oxygen and nutrients And rotten roots, in addition, citrus trees will be necrotic in a large amount in a strong acid environment, and symptoms of aluminum poisoning are prone to occur. Chlorosis caused by blocked transport of nutrients absorbed by the roots
