Winter Spring Melon Fruits and Vegetables
Eggplant, peppers, tomatoes, and watermelons, cucumbers and other fruits and vegetables in the coastal areas of Jiangsu Province are cultivated in winter and spring. They are often caused by damping-off, blight, sclerotiorum, and gray mold in continuous rainy and snowy weather. According to the author's many years of experiments, demonstrations and production practices, the following methods can be taken to comprehensively control the falling seedlings of fruits and vegetables.
First, choose seedbed eggplant, pepper, tomato and other eggplant vegetables using cold bed nursery, seedlings selected leeward sunny, well-drained, soil loose and fertile and 2 to 3 years did not plant eggplant vegetable fields, old vegetable fields (Heavy paddy field) can be sprayed with 40% formalin 100 times 250 ml/m2 for 20 days before sowing, then covered with film for 5 to 7 days, and then uncovered and dried for 14 to 15 days. Also available 50% seed dressing double powder 7 g/m2, or 40% pentachloronitrobenzene powder 9 g/m2, or 25% metalaxyl wettable powder 9 g/m2 + 70% mancozeb Wettable powder 1 g/m2, mix 4~5 kg of nutritious soil, apply water to the seedbed before application, and apply 1/3 of the drug to the surface of the sorghum. After sowing, cover the remaining 2/3 of the soil. On the seed, ie, under the lid, the seed is sandwiched between the herbs. Watermelon, cucumber, and other melons should be used nutrition seedlings or plug matrix hotline nursery. After the broadcast, pay attention to spraying the seedlings and the enemy 1000 times liquid to prevent disease.
Second, the seed disinfection warm water soaking: The filtered seeds of the water into the 52 °C hot water, stirring constantly, and keep the temperature for 30 minutes after washing the seeds with cold water. Seed soaking: The seeds are pre-soaked in clean water for 3 to 4 hours and then immersed in 40% formalin 100-fold for 15 minutes, removed and then rinsed with wet gauze for 2 to 3 hours. Seed Dressing: Use 70% pentachloronitrobenzene or 50% captan for seed dressing in an amount of 0.3% to 0.4% of the seed weight.
Third, to strengthen the seedbed management before sowing nutrition soil (7 pieces of ripe soil, 3 pieces of cooked manure, 1 kg of compound fertilizer added per cubic meter of soil), fine soil preparation, sufficient decomposed organic fertilizer, and adequate water for seedlings. Appropriate sowing amount Solanum species 6 ~ 8 grams / square meter, sow after sowing seeds covered with fine soil, thickness 1 cm, and cover the film. Keep the bed temperature at 25-28°C during the day and 20°C at night, and remove the plastic film immediately after emergence. Solanum seedlings 3 ~ 4 true leaves when the choice of cold head warm sub-miao hypoallergenic, 9 ~ 10 cm plastic larvae per plant per 1 seedlings. Use a small shed to cover the winter. Minimize watering at the seedling stage, and sprinkle with dry fine soil mulch after watering at noon on sunny days. Low-temperature cold weather, pay attention to cover straw insulation antifreeze; at noon appropriate ventilation, reduce temperature and humidity, to avoid leggy. Continuous rain and snow weather, incandescent lamps can be added to the seedbed to supplement light, reduce yellow leaves; combined with disease prevention spray 0.3% potassium dihydrogen phosphate, love over 5000 times liquid.
Fourth, the rational application of pesticides in the early stages of disease prevention and disease removal, concentrated deep. Blemish usually occurs before the cotyledon expands and the true leaves have not yet completely flattened. A 58% Leidavier (metalaxyl manganese zinc) 500 to 600 times, or 75% chlorothalonil 600 times, or 72.2% may be used. Prokary water 400 times liquid prevention. Blight usually occurs in freshly emerged seedlings and large seedlings. It can be treated with 70% thiophanate-methyl 800 times solution or 15% Hymexazin agent 450 times solution. The mixed seedlings with damping-off and damping-off were treated with 72.2% Precloxone 800 times solution and 50% thiram WP 800 times. In winter and spring, severe weather seedbeds with low temperature and high humidity, gray mold, and sclerotium disease often occur mixedly, and 50% quick-acting (Pyritidil) WP can be used for 1000-1500 times, or 40% Shijiale 600-800 times. Prevention and treatment; continuous spring yin, seedlings in the greenhouse, the disease can be used 15% procymidone smoke agent or 45% chlorothalonil smoke fumigation, attention should not be fumigation in the shed, so as not to produce phytotoxicity.
