Prevention and control of vegetable seedling stage

1. Symptoms Seedlings can be harmed after they are unearthed, especially in the middle and late stages. The base of the diseased seed became brown, and the diseased part contracted finely, and the stems and leaves succumbed to death. In the early stage of the disease, the seedlings wilted and recovered at night. When the lesions circled the stem for a week, the seedlings gradually died, and the leaves were wilted and could not be restored until they stood upright. The lesions are initially elliptical dark brown, with concentric circles and pale brown spider silk mold, and the formation of sclerotia in the later stage, is another important feature distinguishing from the disease.
2. Route of transmission and pathogenesis The disease is caused by the infection of the nucleus of the nucleus, and the temperature of the pathogen is 24 °C. If the seeding is too dense, the seedlings or the seedlings are not timely, the seedlings are long, the temperature is too high, the ventilation is poor, or the soil moisture is high or low, and the disease is easily induced. Often infested from roots, young stems and wounds.
3. Control method Seedbed treatment. Refer to the disease.
Seed treatment. Seed dressing with 40% of the seed weight of 40%, or seed dressing with 50% thiram. Strengthen seedbed management. Pay attention to improve the ground temperature, scientific ventilation, and prevent high temperature and high humidity in the seedbed.
In the early stage of the disease, spray 50% of the dry WP 800 times solution, 36% thiophanate-methyl suspension 500 times solution, or 70% mancozeb WP 600 times solution or 5% Jinggangmycin water 1500 times the solution. When the disease is mixed and the blight is mixed, it can be sprayed with 50% Fumei double wettable powder 800 times, 2 to 3 liters per square meter, once every 7 to 10 days, and continuously controlled 2 to 3 times.

HK Door Industry makes Brich Veneer Door Skin, which is very popular in American market because the color and texture of Brich veneer is widely used in making different kinds of doors.

Lacquered solid brich and brich veneer have few differences in appearance. The real difference lies in the makeup of the two materials. They are similar in color, but their densities can range from very hard to almost soft. When lacquer is applied to either one they reflect similar qualities, but have distinctively different applications.

Brich is a North American hardwood. It ranks near the top of the hardness scale and is slightly harder than maple. Solid brich is so hard that it can even dull blades or bits and is typically not used by most craftsmen, who choose instead to use maple, which has grain patterns and colors that are very similar to birch. Solid birch has extremely tight grain with some rippling. It also has a translucent quality, which imparts a glassy effect that is aesthetically pleasing when lacquer is used on the surface. Birch is typically not used much in production woodworking, but craftsmen who build specialty items such as grandfather clocks are rewarded by its unique properties.
