At present, the late-maturing apple in Shaanxi has entered an expansion period. At this time, the nutrient consumption of the tree is severe. In addition, the recent drought and drought, some orchards in early pre-management poor tree vigor, pest damage seriously. Remind the broad masses of farmers to timely carry out the prevention and control of pests in the later stages of the orchard, and lay a good foundation for the production of high-quality and high-effect products.
1. Agricultural control: Strengthen field management, reasonably pruning, cut off long branches and diseased branches, and improve ventilation and light conditions in orchards. After falling fruit trees in autumn, branches are painted white and deep into the soil. And timely clearing of fallen leaves, concentrated deep or out of the park burned, reduce the incidence of disease.
2. Physical trapping: From late August to early September, traps are trapped on the upper part of the trunk or the base of large branches. When the pests are dormant, they will go to their houses before the outbreak (in February of next year). It is best that the natural enemies climb out after the convulsions. The trap belt was brought out of the park and burned.
3. Chemical control and prevention: First, one week after fruit harvest, use a mixture of long-lasting insecticides and broad-spectrum fungicides and pesticides. Spray trees in accordance with the recommended dosage. Second, scrape the rot to treat the lesions. After the newly emerging rot morbidity spot is found, apply a 3% thiophanate-methyl paste undiluted solution or a cystathine acetic acid saline solution or a 45% dexamethasone solution. Or 50 times solution of thiazolyl to smear lesions to prevent further expansion of rot disease.
Natural pigments are food pigments obtained from natural resources. Pigments extracted mainly from animal and plant tissues and microorganisms (cultures), in which vegetative colorants predominate. Natural pigments not only have the function of coloring food, but also have physiological activity. At present, there are 48 kinds of edible natural pigments approved to be used in China, commonly used chili red, beet red, monascus red, cochineal red, gaolianghong, sodium copper chlorophyllin, turmeric, gardenia yellow, carotene, algal blue pigment, cocoa pigment, caramel pigment and so on.
