The millet's spicy pericarp grown in Jianshui is smooth and has good glossiness and product characteristics. Especially processed products pickled with green peppers have bright color and crisp texture. They are well-known by the merchants both inside and outside the province and are the major bulk exporters in Jianshui County. One of the vegetable varieties has a high reputation both inside and outside the province. The Xiaomi spicy planting area in the county is 55,000 mu, and the output is more than 50,000 tons. It can be called the hometown of millet spicy in China. Virus disease is the most common disease in Xiaomi Spicy Production in Jianshui County. It has the characteristics of rapid occurrence, rapid epidemics, etc., and often causes serious losses in the production of Xiaomi Spicy. Due to the long duration of high-temperature drought in the early part of this year, Xiaomi Spicy Virus disease was seriously endangered. In order to help farmers identify the disease correctly and to prevent it in a timely manner, special prevention and control measures are proposed as follows:
1, millet spicy virus disease is a common disease, the performance of leaf curl deformity, plant atrophy is not long, light green leaves, in the flowering period of disease, resulting in flowering and fruiting and interval flowering results, so millet spicy taste bitter, yield Low, poor quality. Since the millet is a vegetable with a very short harvest interval, it is generally harvested every 2-3 days. During a large number of flowering results, it is harvested almost every day. In order to prevent the millet from being contaminated and ensure food safety, it must be taken as pollution-free. Technical measures to prevent viral diseases.
2. Disinfect the seeds in time to weaken the virus activity in the seeds. Before sowing, first wash seeds 2-3 times with 0.1% potassium permanganate aqueous solution to remove germs on the seed surface; then soak the seeds in 0.1% zinc sulfate aqueous solution for 10-15 minutes, then pick up the seeds and use clean water. After cleaning, sow. In this way, plants are rarely infected with virus disease in the future.
3. Strengthen field management. Improve disease resistance. Suitable for early sowing, do not connect with solanaceous crops, apply more phosphorus and potassium fertilizer, do not apply nitrogen fertilizer. Clean the garden, reduce the source of bacteria, bring the former crops out of the field, concentrate on treatment, and dig deep. After the seedlings are transplanted to survive, every 10-15 days, the roots are watered with 83-fold increasing agent 100-fold liquid, and foliar spray 0.2% potassium dihydrogen phosphate and 0.1% zinc sulfate, A800-fold mixture of virus, or spraying disease 1300 times, spray once every 7-10 days. Timely prevention and control of locusts, jaundice, whitefly and other media pests, the eradication of these pests before flowering, can significantly reduce the incidence and damage of viral diseases, before flowering, can be used once again net 1000-1500 times fluid, or 7.5% worms Emulsion 2500 times, spray once every 10-15 days, continuous spray 2-3 times.
4, pest control disease. Shade cultivation of locust control, can be intercropped with corn and other high-crop crops to reduce the incidence of viral diseases. Take every row of millet to plant a row of corn in an intercropping manner. Because corn plants are tall, they can play a role in attracting mussels. At the same time, during the hot fruit season of Xiaomi Spicy, the tall corn plants can also make Xiaomi Lam free. Exposed to the sun. In April-June, when the scorpion moved into millet stalks, spray 20% diclofen 800-1500 times, 10% imidacloprid 2000 times or 2.5% dichlorfon 5,000 times, and 10% NET. WP 2000-5000 times, kills vector insects and reduces transmission. Spray virus passivation agent, spray 5% bacteriostatic water solution 500 times, 20% virus water solution 500 times, and 20% virus nemesis wettable powder 3-5 days before the transplant and colonization of millet. 500 times liquid, antiviral (0.5% mushroom proteoglycan water) 200 to 300 times or 20% virus A WP 500 times, 1.5% phytolionic R emulsion 1000 times, or attenuated N14 Ten S52, or NS-83 anti-agent 100 times the liquid, anti-toxic agent No. 1 200-300 times liquid, every 10 days or so, continuous control 3-4 times.
