1. Nursery time. The pepper breeding time varies from region to region. Generally, the middle and lower reaches of the Yangtze River are sown in October-November, and planted in North China and Northeast China from April to April, and planted in South China from December to January. Pepper seedlings in the southern region are 90 to 100 days old, and about 60 days in the north. The criteria for strong seedlings before planting are as follows: thick stalks are short in internodes, leaves are hypertrophic in color, stems and leaves are intact without pests, white roots are developed in the roots, and 9 to 14 true leaves are present. The cotyledons are intact and the roots are well developed.
2. Seedbed selection. Choose sunny, fertile soil, convenient water source, no oysters or oysters have been planted on the plots of peppers with the same crops (such as pepper, cabbage, eggplant, tomatoes, potatoes, etc.) for the seedbed. The area of ​​the seedbed is generally 1% of the area of ​​the field. After the seedbed is selected, the bottom water should be poured.
3. Seed treatment. Sowing before sowing 2 days, soaked with water for 3 to 4 hours, and then soaked with 10% trisodium phosphate solution 1000 times for 10 minutes, washed with water and then soaked in warm water at 55 °C for 10 minutes, and constantly stirring, replenish warm water at any time Maintain 55°C water temperature. Then remove the seeds and germination for 24 hours.
4. Soil preparation. After the seedbeds were watered, 500kg chicken manure, urea 1.5kg, superphosphate 5kg, and 15kg ash were fertilized per 667m2. Spread the fertilizer and pour over 15cm, dip and dry it to make a wide sorghum, 7 to 10m long, 1.2m wide, 0.85m wide, 0.4m apart, and 0.1m deep. After the seedlings are ready, they should be sowed immediately. Each seed should be sown with 200g, covered with lcm, and covered with a 0.9m wide plastic film. The film is stretched and flattened, and it will be tightly pressed around. After the plastic film is well covered, a plastic shed can be used to make a small shed. The height of the shed is 0.5-0.6m. Soil preparation, sowing, and filming should be done quickly to prevent running. Small greenhouses can also be nursed in plastic greenhouses or in greenhouses.
5. Seedbed management. 1 temperature. The daytime temperature is controlled at about 25°C and 12-15°C at night. When 60% to 70% of the seedlings are uncovered, the plastic film is peeled off. When the temperature rises at noon, attention is paid to cooling and preventing burning. 2 moisture. The soil moisture in the nursery area should be relatively small. When the seedlings have 2 to 3 true leaves, the soil drought can be sprayed with a watering can. When the 4 to 5 leaves encounter a drought, the ditch can be filled with water, so that the water slowly seeps into the soil in the pot. The water must be filled to reduce the number of irrigation. 3 sparse seedlings. When the seedlings grow to 1 to 2 true leaves when the seedlings are sparse, they are weak and strong, and weeds are removed. Keep the spacing between 3 and 4 cm, and leave 17,000 plants per plant. 4 practice seedlings. 15 days before planting, a small hole at the top of a small arch to break the wind to practice seedlings, so that the seedlings gradually adapt to the external environment, improve the survival rate of transplanting. 5 Pest control. Pepper seedlings often suffer from blight, damping-off and other diseases. Once a diseased plant is discovered, it must be removed promptly. If the disease has a tendency to develop, drug control should be carried out in a timely manner, and carbendazim and anti-virus drugs can be used.
Note: The seedbeds should be watered before the planting to reduce the damage to the roots when they are raised and shorten the time for transplanting after transplanting.
Biological fingerprints have the characteristics of uniqueness and stability, without the permission of the highest authority of the manager, any individual without qualified fingerprints can not enter. Therefore, the fingerprint safe relative to other categories of safe, a good solution to the problem of others imitation keys to open the door. If you use a traditional mechanical safe, you may face risks such as having a key made by others or using a special unlocking tool to open the lock.
