I. Phyllostachys pubescens disease
1, symptoms. Occurs at the twig of the new shoot or branch. At the beginning of the lesion, it was light brown and gradually expanded into a prismatic or irregular shape. The color was purple. When the lesions circumnavigate around the main branches or branches, the leaves above the lesions begin to wilted and curl up, and then become yellow and fall off. In the spring of the following year, many bulging black grainy fruiting bodies grew out of the lesions.
2, prevention and treatment. (1) The elimination of diseased plants and diseased branches before the production of fruiting bodies is an effective method of preventing pathogens. (2) 50% carbendazim wettable powder 1:500-1000 times liquid; 50% thiophanate powder 1:500-1000 times liquid; 1% Bordeaux mixture control, continuous spraying 3-4 times.
Second, bamboo rust (also known as bamboo ridge disease)
Harmless white chicken bamboo, bamboo, bamboo, carnation and so on.
1, symptoms. After the bamboo raft was killed, the sick department became dark and brittle, which made the bamboo forest grow weaker and weaker, resulting in a significant reduction in shoots, and in severe cases the whole plant died. Lesions often occur in the lower and middle parts of bamboo rafts. In May-June, yellow-brown or dark brown, dot-like or broad-striped mats are produced, which are the pathogenic uredia spores. After the summer spores fell off, the diseased part was dark brown and spread to the edges of the lesions and appeared yellow spots. The macular is spot-like or wide-striped, rust-colored, and leathery mat-like, which is the teliospores heap of pathogens.
2, prevention and treatment. (1) The diseased plant was found to be cut off early and burned. (2) Reasonably leave bamboo not to make it dense. (3) Prior to the generation of teliospore in November, spray with 0.5-1 Baume degree limestone or 1% solution of diuretic sodium, once every 7-10 days, 3 times in succession. (4) It can also be sprayed with the above-mentioned drugs from late May to early June (ie, the period of bamboo leaves spreading), which can prevent the generation of summer spores and prevent spores from spreading.
The top-mounted motor, the triangle tape, and the drive drive assembly make the inner cylinder run forward and reverse, and the washing effect is achieved through the mutual friction between the fabric and the fabric, and the fabric and the inner cylinder wall. The machine has built-in overheating, overload device, timing device, forward and reverse control device. The outer cylinder door is equipped with a safety device. If the door is opened during operation, the machine will stop running immediately to ensure the safety of the machine and the operator.
