In the clearing of the garden, the high-temperature composting in a place far away from the orange orchard can eliminate many pathogens and pests that overwinter in these places. Therefore, in winter, winter pruning should be combined to remove diseased branches, dig out dead trees, and eradicate weeds. At the same time, scrape off the moss, lichen, etc. on the trunk to eliminate overwintering pests and places on the tree. Cultivation loose soil, like flower bud maggots and other pests, generally live in the soil as larvae, and fruit flies and geometrids live in the soil as pupae. Therefore, deep plowing of the garden soil during the overwintering period can cause mechanical damage to the larvae and pupae of pests such as fruit flies, flower bud maggots, or death due to environmental discomfort, effectively reducing the insect population of the orange garden in the coming year. Drug prevention and treatment If the orange tree bark tissue that is deadly infected with resin disease is found, the diseased part should be scraped off, and the wound can be disinfected with 75% of the essence and smeared with medicine. The medicament has 75% carbendazim wettable powder 100 times liquid, or 1% antibacterial agent 402, etc. It can also scrape the lichen and moss growing on the base of the trunk. Scrape foot rot spots, cracked and dead citrus tree bark, in order to apply protective agent. At the same time, combined with the clearing of citrus gardens, 80-100 times the oil emulsion can be sprayed, and the acaricides such as Quick Cull and Kemite can be added to effectively kill overwintering rust ticks and scale insects. , Red spiders and other pests, but also can control lichen, moss and soot. It is also possible to spray an aqueous solution of lime-sulfur mixture with a degree of 0.6-0.8 Baume on the canopy once or twice in winter. For orange orchards with serious scale insects, spray 10 times the rosin mixture, but the rosin mixture and lime sulfur mixture should be used more than 15 days apart to prevent phytotoxicity. Sprinkle 5% to 10% tea dry water or lime water , It can effectively kill the larvae of various pests that overwinter in the topsoil layer or soil cracks.

Generally, food additives may not be food and may not have nutritional value, but they must conform to the concept of the above definition, that is, do not affect the nutritional value of food, and have the function of preventing food spoilage, enhancing food sensory properties or improving food quality. buy food Additive ,wholesale food Additive,food Additive for sale,food additive benefits Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptidenootropics.com
For whitening, first sweep the stems and branches that need to be whitened, and then perform whitening. If the tree trunk has large cracks, or there are tree holes or wormholes in the tree, use cement, or use fine river sand, or use fresh cow dung, lime, yellow mud mixture, etc. to block the wormhole. You can also use absorbent cotton dipped in 80% dichlorvos emulsion, or 5-10 times of 40% dimethoate EC, stuffing it into the worm hole and then blocking it, the insect removal effect will be better.
Generally speaking, food additives can be divided into natural and synthetic categories according to their source. Natural food additives refer to natural substances extracted from the metabolites of animals, plants or microorganisms as raw materials. Chemically synthesized food additives refer to substances obtained by chemical means through oxidation, reduction, condensation, polymerization, salt formation and other synthetic reactions of elements or compounds. Most of the chemicals used today are synthetic food additives.
According to the use, the classification of food additives in various countries is almost the same, the difference is mainly the difference in the classification of how much. The United States divides food additives into 16 categories, Japan into 30 categories, China's "Health Standards for the Use of Food Additives" divides them into 22 categories: Antioxidant preservatives (1) (2) (3) (4) bleach hair color agent (5) concreting citric acid (6) (7) loose agent (8) thickening agent defoaming agent (9) (10) sweetener (11) colorants emulsifier (12) (13) improver (14) anticaking agent (15) flavor enhancer (16) (17) of enzyme preparation was preparing foaming agent (18) (19) preservatives (20) spices (21) nutritional fortifier (22) other additives.
