The diseases of hawthorn are mainly flower rot and powdery mildew. The pests mainly include peach borer and red spider mites.
1. Hawthorn flower rot mainly damages leaves, shoots and young fruit, resulting in erosion of damaged parts. The onset of the leaves, brown spotted or short line-shaped lesions occurred initially, and then gradually expanded into a reddish-brown or tan color, the diseased leaves were withered.
1 In the autumn, the orchards will be completely cleaned up, the sick and stale fruits will be eliminated, and they will be destroyed and buried in depth to reduce the sources of infestation.
2 Turning the ground in early spring: Deeply plunge the sick ground fruit to a depth of 15 cm or less.
3 Ground spraying: Before the end of April, lime powder was sprinkled on the ground of the orchard, especially under the canopy.
4 Pharmacy tree control: 50% leaf spray and two leaf sprays were used to prevent leaf rot. There are 25% of the powder rust Ningken 1000 times liquid, 70% thiophanate-methyl wettable powder 800 times. The flowering period will be sprayed once again to prevent flower rot and fruit rot.
2. Hawthorn powdery mildew mainly damages leaves, shoots and fruits. Occurrence of the leaves, the Ministry of cloth white powder, was carpet-like, that is, conidial stems and conidia, new shoots victims, in addition to the emergence of white powder, the growth of thin. The internodes are shortened, the blades are slender, the curls are twisted, and when they die, they die.
1 Clean up the orchard, clean the diseased branches, diseased leaves, and diseased fruits and centralize the destruction.
2 Chemical control: spray 5 degree lime sulfur before germination, increase aerial spores during flower buds, spray 5 degree lime sulfur, spray 1-2 times of 0.3-degree lime sulfur or 25% triadimefon after falling to young fruit. -1500 times liquid.
3, peach borer
In mid-June, 100-150 times parathion EC was sprayed on the tree tray to kill the overwintering borer borer larvae. In early July and mid-August, 1500 times parathion EC was sprayed on the trees to eliminate the fruit borer larvae.
4. Hawthorn red spider
1 In the early spring, scrape the old skins and cracks on the trees and destroy and eliminate overwintering adults.
2 spray pyrethroids 2000 times, 20% trichloro cyanide EC 800 times, 73% Kraft EC 2000 times and better ovicidal 50% Nisuo EC 2000 times, specific spraying opportunities and The number of times should be judged based on the amount of occurrence and the effectiveness of combat effectiveness.
Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
