Tomatoes are one of the common types of vegetables. Due to its long growing period, the cultivation methods include early spring cultivation in spring, delayed cultivation in autumn, autumn and winter cultivation, winter and spring cultivation, and open cultivation. There are many kinds of pests and diseases, and the use of drugs is more frequent, which can easily cause excessive pesticide residues and affect people's health. We must implement the plant protection policy of "prevention first, comprehensive prevention and control", prioritize the use of agricultural and biological measures, and use pesticides scientifically to comprehensively treat pests and diseases, reduce pesticide use, and protect the environment and personal safety. I. Major pests and control indicators Overbearing disease: the diseased plant rate is 1%-3%; virus disease: when no diseased leaf is found; gray mold: when the diseased leaf is initially seen; aphid: 5-7 plants per plant. Second, comprehensive management technology Can be divided into pre-planting, seedling stage planting to the result period, to be phased governance. 1. Before sowing (1) Soil disinfection. 1 daylight disinfection. Protected cultivation of high temperature season in summer deep-turning more than 25 cm, and then lay the film for 10-15 days. 2 Pharmacy disinfection. After sowing, cover with 1:50 Carbendazim. (2) Selection of comprehensive pest-resistant varieties Lu tomato No.2, No.6, Xifen No.3, Baili, Yuxi No.3 can resist mosaic disease, Shuangkang No.2 can resist leaf mold, Qiang Miso, Xi'an Dahong, etc. can resist wilt disease. Zaofeng, Zhongcai No.2, No.4, No.6, Qiangfeng, Qiyan Dwarf Powder, No. 2 Lutong, No. 2 Dahong, Maofen No. 802 and so on all had better yield resistance. The above varieties can be adapted to local conditions. (3) Seed disinfection. 1 Warm scalding: Soaking in warm water at 55°C for 10-15 minutes, or immersing in warm water at 50°C for 20-30 minutes. When the water temperature drops to 30°C, stop stirring and soak for 6-8 hours to kill a variety of germs. 2 drug treatment. 50% carbendazim 500 times soaking for 2 hours to prevent fungal diseases. 2. Seedling period. In this period, we mainly deal with damping-off and prevent viral diseases and gray mold. (1) Agricultural measures. 1 properly control the watering, after the emergence of a small amount of dry soil or grass and wood ash caulk, gradually ventilation and cooling, timely seedlings. 2 open field nursery cover insect nets, locust control, whitefly, to prevent virus disease. 3 When the diseased seedlings were found, they were immediately removed, brought out of the seedbed and buried deeply, and treated the diseased points. (2) Biological measures. 1 Protected areas can be inoculated with weak virus strains to treat seedlings to control viral diseases. 2 Spray 100 times liquid of NS-83 increasing agent (mixed fatty acid) before and after colonization. (3) Ecological control. Control seedbed temperature and humidity, daytime temperature 25°C-27°C, no less than 15°C at night. (4) Drug control. 1 Control of damping-off disease, 72.2% Preclosure 800 times or 70% dexamethasone zinc WP 500 times, can cure gray mold, blight. The protected area can use 5% chlorothalonil dust agent 667 square meters with 1 kilogram, or 45% chlorothalonil aerosol 667 square meters with 250 grams, and prevent a variety of diseases. 2 control aphids, can be used 1.8% avermectin EC 3000 times or 2.5% Kung Fu EC 2500 times spray. 3. Colonization to the result period. The duration of this period is long, and the main control objects are virus diseases, whitefly, roundworm, cotton bollworm and so on. (1) Agricultural measures. 1 Remove diseased leaves, diseased flowers, and diseased fruits in a timely manner, and remove the old leaves with no promotion function in the lower part and destroy them in a centralized manner. 2 timely ventilation and cooling, control watering, rainy days do not water. (2) Biological measures. 1 yellow trap. Protected areas can be set up to trap whiteflies, aphids, and other insects that have a tendency toward yellow color. 2 Ecological control. On the sunny side of the protected area, it is appropriate to release the winds in the late evening, so that the shed quickly rises, and when the shed temperature rises to 30°C. At that time, it began to release air; when the shed was wet, it dropped to 20°C. At that time, close the vents to delay the temperature drop; the night temperature is maintained at 12 °C -15 °C to prevent gray mold, leaf mold and epidemic diseases. (3) Drug control. 1 Use 20% virus A wettable powder 500 times at the seedling stage to prevent viral disease at the early stage of disease. 2 Use 1% agricultural anti-wuyimycin agent 150-200 times, in the early stages of disease prevention and control leaf mold, gray mold. 3 Use 1.8% Avermectin EC 3000 times to control leafhoppers, cotton bollworms, etc. 4 Use 72% of agricultural streptomycin sulfate soluble powder 3000-4000 times, or 25% of the dry powder wet powder Liu 500 times spray control bacterial diseases. 5 Disinfection of pesticides in protective areas. Before planting, the protected area was sealed and 1 kg of 5% chlorothalonil dust agent was used for 667 square meters. Or use 45% chlorothalonil aerosol with 250 grams per 667 square meters. Or use 75% chlorothalonil 500 times solution to evenly spray and seal the walls, floors, bamboo rods, and columns in the protected area. 6 control of aphids, whitefly can be used 10% Dagong Chen WP 1000 times, or 40% of Chrysanthemum killing 3,000 times, can be concurrent treatment of cotton bollworm.
The yellow mealworm is not only rich in protein, fat, polysaccharid and other organic macromolecular nutrients, but also rich in phosphorus, potassium, iron, sodium, aluminum and other trace elements. For every 100g of the yellow mealworm larvae, the protein content of dry powder is between 48% and 54%, the fat content is between 28% and 41%, and the contents of vitamin E, B1 and B2 are also high. Therefore, the yellow mealworm can provide high quality protein for the medicinal animals, and make the animals high in nutrition and pesticide effect.
