Rust: In the autumn and early spring, the disease center was found in the field and spraying control was conducted in time. If the diseased leaf rate reaches 5% and the severity is below 10%, use 15% triadimefon 50g or 20% Triadimefon 40ml per 667m2 per 667m2, or 25% triadimefon per 667m2. 30g of rice, or 12.5% ​​speed Baoli WP can be used 15-30g per 667 square meters, 50-70kg of water spray, or low volume spray of 10-15kg of water. In disease epidemic years, if the diseased leaf rate is above 25% and the severity exceeds 10%, the dosage should be increased. According to the severity of the disease, spray with 2 to 4 times the above dosage.
Fusarium head blight: It can occur from seedlings to heading, causing seedling blight, stem rot and ear rot. In the wheat flowering period to flowering period: 18% carbendazim powder 50 grams per 667 square meters, or 40% carbendazim suspension 50-75 grams per 667 square meters, or 50% carbendazim WP 100 grams per 667 square meters; 270% thiophanate-methyl wettable powder 50-75 grams per 667 square meters or 50% thiophanate-methyl wettable powder 75-100 grams per 667 square meters, respectively 65 kg of water spray, Or add 10 to 15 kg of water for low volume spray. If it rains continuously during the flowering season, apply the medicine once again after the first dose 7 days after the first application.
Wheat spiders: Wheat spiders attack the wheat seedlings in spring and autumn, and both adult and adult nymphs can be harmed. The damaged wheat leaves appear yellow and white dots, and the plants are short and stunted, and the heavy ones die. After spring wheat returns to green, select a heavier wheat field in the area to conduct the survey, then take 5 points, check 33 centimeters per point, place a white plastic cloth or a pot of water, and tap the wheat plant to record the number of fallen insects, when the average number is 33 If more than 200 centimetres of larvae are thrown in centimeters and white spots are found in 20% of the upper leaves, chemical control should be carried out. 1 spray powder. It can be used with 3% chlorimicarb or 1.5% dimethoate for 1.5 to 2 kg per 667 square meters. 2 spray. 50% Malathion 2000 times, 667 square meters 75 kg liquid. 3 poisonous soil. 40% Dimethoate emulsifies 20 kg of fine soil per 75 g of 667 square meters and sprinkles in the field. The effect is more than 80% in 48 hours.
Wheat bran: It can occur and harm throughout the entire wheat breeding process, and has a great influence on wheat yield. First of all, we must check the pest situation. After the winter wheat jointing season, after the emergence of spring wheat, every 50 days to the wheat field, randomly take 50 to 100 plants (when the amount of wheat bran is large can reduce the strain) to investigate the amount of calamities and the number of natural enemies. (Stem pods) more than 500 shots, when the ratio of natural enemies to locusts is 1:100 or more, they need to be controlled. 1 seed treatment. In the wheat yellow dwarf endemic area, seed treatment can prevent and cure the disease. Specific methods are described in the "Wheat Yellow Dwarf Disease" pesticide seed dressing. 2 field spraying. Available 1.5% dimethoate powder, 1.5 to 2 kg per 667 square meters. Spray 2000 times with 50% phoxim EC, or 4000 times with Humidel WP. In the prevention and treatment at the earing stage, we should consider the combination of wheat rust and powdery mildew, sticky worms, and wheat bran, and use 6 grams of triadimefon per 667 square meters, 6 grams of anti-indolazole, and 2 grams of diflubenzuron (the three are referred to as active ingredients). The above pest control effect of 85% to 90%.
Midge: Red midge and yellow midge. Both midge insects suck grazing granules in their larvae, causing pods and empty shells. In the great year, the whole field can be destroyed and the grain can't be harvested. First check the density of larvae by scouring the soil. Select 1 to 2 blocks of representative fields and randomly pick up 7 to 10 small earthworks with a size of 101,020 cm. After evenly mixing, pour 1/7 to 1/10 soil samples into a bucket. , Add water to stir, after precipitation, pour the mud into the copper yarn screen, filter out the muddy water, and then scrape off the debris on the sieve and check the worms left on the sieve. Repeat the panning several times to check the insects. The second is to conduct a survey of adult trapping insects in the early stage of wheat heading (the diameter of the insect catching net mouth is 30 cm), walk in the wheat field, and catch the net 10 times to record the number of insects. When there are more than 5 insects per small earth on the average wheat field, it needs to be controlled. In the early stage of wheat earing, 10 to 25 adult worms were caught on average 10 times, requiring immediate control. The time of prevention and treatment is appropriate for the mid-supreme period, and the adults are assisted in prevention and control. Use 50% phoxim EC 200 ml and add 5 kg of water. Sprayed on 20-25 kg of fine soil, mix well into poisonous soil, while spreading and ploughing, into the soil. Soil application should be promoted to eliminate the killing effect of the midge on the larvae before they are unearthed.
Firstly, fresh and mature fruits with good quality were selected in the pre-treatment area of the food lyophilizer, and the leaves were removed to remove impurities. Then, preliminary cleaning and simultaneous sterilization of fruit surface were carried out. After sterilization, the fruits were cleaned and drained again. After the drain, the fruit is sliced and treated by blanching process. After the color preservation, the fruit is treated by pulping, and then pasteurized. The pretreatment process is finished before lyophilization.
The processing core of freeze-drying powder is the equipment area of food freeze-drying machine. After pre-treatment, the fruit enters the equipment of food freeze-drying machine and crystallizes into a solid state at low temperature, and then sublimates and dries in a vacuum environment to obtain freeze-drying products with little water content. Freeze-dried products out of the warehouse into the food freeze-dried post-processing area, ultrafine grinding, and then according to the need to do weighing packaging, after testing the finished products packed into storage.
Wheat's "two diseases, three pests" control technology
Wheat, two diseases, three worms are rust, head blight, wheat spiders, wheat aphids, and midge pests. They are harmful to wheat and should be treated with caution.
