First, cultivate nutritious soil. From the plots planted with green onions, garlic or plants that have not been planted with solanaceous vegetables in recent years, mix them according to the ratio of vegetable garden soil, decomposed cow dung and manure, and then add the equivalent of cultivated soil weight. 0.1%-0.2% of superphosphate, the prepared nutrient soil is filled into the nursery bed, compacted and leveled.
Second, seed disinfection. Soak seeds with warm water at 55 ° C, or soak seeds with 10% aqueous solution of trisodium phosphate for 20-30 minutes, rinse off, rinse with water, and then germination.
Third, the appropriate sowing. The appropriate sowing date should be accurately estimated based on the colonization period. Before planting, the seedbed should be poured with the bottom water, then planted, planted with soil, and covered with mulch.
Fourth, temperature management. Generally, the solanes and vegetables should be kept until 25-30 °C before seeding; it is better to keep 20-22 °C during the day after emergence, and 15-16 °C at night; to transplant until the seedlings are kept 25- 28 °C is appropriate, it is better to keep 20-25 °C during the daytime, and 15-18 °C at night; 7-10 days before planting, low temperature refining should be carried out to improve the survival rate of the planting of solanaceous vegetables. .
Fifth, lighting management. The solanaceous vegetables like strong light, grow strong under strong light, and get sick under low light. Specific lighting management measures are: 1. Glass or plastic film should be kept clean to reduce water and dust accumulation and improve light transmittance. 2, in the case of guaranteed temperature, try to expose the scorpion as early as possible to extend the hours of illumination. 3. Hang the reflective screen to increase the light intensity and the light receiving area. 4, cloudy days also reveal the scorpion.
Sixth, water management. Pour the bottom water before sowing; do not water immediately after sowing; water once when the seedlings are planted; watering from one end at a time, not repeated back and forth. After each watering, when the leaves are free of water, sprinkle some dry soil or grass ash to help protect the sputum, prevent the knot and soil temperature from decreasing, and avoid watering in rainy days.
7. Refining seedlings before planting. At 5-7 days before planting, low temperature refining at night is carried out. If the seedlings are too tender, in order to protect them from cold, you can use a higher temperature (7-10 °C) for several days, and then further refine the seedlings. The suitable temperature for general solanaceous vegetable smelting is: 3-5 °C for tomato; 8-11 °C for eggplant and pepper, and 3-5 days for refining time. After the low temperature exercise, the solanaceous vegetables can significantly improve the adaptability, can endure the general frost, and after planting, the seedlings are fast and the trees are early. In addition, the method of enlarging the seedling distance, uncovering the film and drying the seedlings, etc. can also be used to promote the seedlings to be strong and enhance the resistance to stress, thereby improving the survival rate of the planting.
