I. Camellia leaf blight
Tea leaf blight is a common and serious leaf disease in tea plants. The disease is widely distributed throughout the tea area. Victim strains often grow poorly, new plants are not strong, heads are thin and weak, and premature ageing is not enough, seriously affecting yield. The disease prevention method:
1. Strengthen management and cultivate robust tea strains. Rational use of pesticides to avoid the occurrence of phytotoxicity; timely cultivating and weeding, loosening the soil; doing a good job of tea garden drainage or drought, cold work, creating an environment conducive to the growth of tea trees, promoting tea tree robustness, and improving disease resistance.
2. Clean up the garden and reduce the source of germs. For seriously ill tea gardens, the diseased leaves should be removed during the winter and spring period, and litters should be cleared or winter plowing should be conducted in the tea plantation. The topsoil should be buried deeply to prevent the disease. During the onset, diseased leaves are removed to prevent infection.
3. Spray pesticides in time to control the spread of the disease. Due to the occurrence of this disease, there is a certain relationship between it and small green leafhoppers, mites, black rot and red rust. Therefore, prevention and control of the disease should be combined with the prevention and treatment of the above pests. Optional spray the following agents: 0.6% of the lime half Bordeaux mixture (20 days after spraying can be picked), 70% thiophanate-methyl wettable powder 1000-1500 times, agricultural antibiotics 30-30 ppm of the release agent (after spraying 5 Days to pick), antibiotic antibiotics lppm (7 days after spraying can be picked), 80% zein zinc WP 600-800 times (15 days after spraying can be picked), spray amount of 60-75 kg per mu , Spray once every 10-15 days, spray twice. In unpicked tea gardens or nurseries, the above-mentioned agents can also be sprayed. Can also be based on the actual situation, appropriately shorten the time, increase the number of spraying, in order to achieve better prevention purposes.
For tea green leafhoppers and acarids, the following pesticides can be sprayed according to the pest situation: 40% dimethoate emulsion 500-1000 times, 90% dipterex crystal 500 times, and 80% dichlorvos emulsion 500 times. These insecticides cannot be mixed with alkaline pesticide Bordeaux mixture, otherwise it will reduce the efficacy and cause phytotoxicity.
Second, tea cake disease
Tea cake disease is a fungal disease. It is a common disease and is an important disease in high mountain tea areas. The disease mainly invaded the young buds of tea trees, which not only had a great impact on the yield, but also produced dry tea made from damaged tea. It was bitter, brittle, and had many fragments. The quality was significantly reduced. The prevention and treatment of the disease:
1. Strengthen seedling quarantine. All diseased tea seedlings, scion and cuttings should be forbidden in the ward to protect the disease-free zone and the new tea garden.
2. Strengthen tea garden management. Divide the weeds; regulate the types of fertilizers and the application period, add appropriate phosphorus and potassium fertilizers, avoid partial application of nitrogen fertilizer; timely pruning, remove diseased branches and leaves.
3. Reasonable tea picking. After the end of September, in case of cloudy weather and low temperature weather, picking in batches should be carried out in a timely manner, using 1 bud left 2-3 leaves fish leaves, and picking buds (diapause buds) timely picking clean .
4. Elimination of germs over summer sites. In the heat of the summer, the germs cannot spend the summer in the tea gardens and have high temperatures in the summer. They can only continue to infest and overshadow the shaded tea trees. Therefore, it is an important measure to strengthen the management of tea gardens to make the tea gardens airy and clear to eradicate the over-summer places of pathogens.
5. Chemical control. The available pharmaceutical agents include carbendazim, thiophanate-methyl, and thiophanate-methyl and other organic biocides. Per acre election spray the above-mentioned agent 500-1000 times, mu spray 75-100 kg, spray once every 10 days, a total of spray 2-3 times (spray can be picked after 15 days). If there is no such agent, it can be sprayed with 0.6% lime Bordeaux mixture, spray 75-100 kg per acre, spray once every 10-14 days (20 days after spraying can be picked).
Third, tea black rot
Tea black rot is also common in some tea areas, and the incidence of severe strains is as high as 52%. If the control is not good, not only will the tea be reduced year after year, but the tea tree will gradually weaken and even die. Its prevention method:
1. Combine pruning to remove diseased foliage and reduce bacteria source. Seriously diseased tea gardens should be heavily pruned, and pruned diseased branches and leaves should be removed and burned. After the pruning, spray the 0.7% lime double Bordeaux solution once, spraying 60-75 kg per acre.
2. Improve the environment around the tea garden and enhance the permeability of the tea garden. Remove the dense trees and weeds in the surrounding forests, shrubs, etc., to make the tea gardens airy and clear.
3. Strengthen inspection, early detection, timely spraying and prevention. Frequently inspect the leaves for disease. Once they are found, remove the diseased leaves and block the spray to prevent spread. Spraying agents: 0.7% lime equivalent Bordeaux fluid, 75 kg per mu, spraying every two weeks - times (20 days after spraying can be picked); 2% Kong toxin 1000 times, 60-100 kg per mu, Or 5% Tianan Shui agent 600 times, or 50% carbendazim WP 800-1000 times, or 70% thiophanate-methyl WP 800-1000 times, or 50% Humuli emulsion 800- 1000 times liquid, 75-100 kg per mu.
Corn has a more complete nutritional profile, making it ideal as a preferred food for scientific fat loss.
Generally speaking, sweet corn favors vegetables and sticky corn favors staple foods.
This classification is for the sweet corn (vegetable).
There are generally two ways to lose fat scientifically: exercise and controlled diet. Both are indispensable and must be combined for effective fat loss. Especially for people who are not particularly obese, we should consider the combination of exercise and diet control. In terms of diet control, take care that the daily intake of food is based on high quality protein and vegetables.
1. The time and intensity of exercise should be gradual. Exercise more than 1 hour a day is good.
2. exercise to control their mouths, eat less sugary food. If you are more gluttonous, you can use fruit sweet corn to satisfy your cravings. Fruit sweet corn is sweeter to eat, but it is low in sugar and satiety, which can help you control your diet.
