Now the temperature in various regions is rising, and the temperature of the Ching Ming Festival will generally be above 10 °C. At that time, it is a good time to grow vegetables. But no matter which kind of seed, many people always encounter the situation that the seedlings are not seeded or the seedlings are not neat. In fact, if the vegetable sowing is to be quick and good, then the following three points are crucial. First, the germination temperature of different seeds is different The germination temperature required for different vegetable seeds is different. Before planting, we need to understand the temperature conditions commonly known as germination. 1. Low-temperature sprouted vegetables include lettuce, chrysanthemum, spinach, celery, onion, onion and carrot, cruciferous vegetables, etc., and germination is best at 15-20 °C. 2, warm germination with watermelon, cucumber, pumpkin and melon, etc., the best germination temperature is 25-30 ° C is appropriate. 3. The suitable temperature for solanaceous vegetables such as eggplant, pepper, tomato, etc. is 23-28 °C. Second, different vegetable seeds cover different soil After sowing, the soil is very particular. The thickness of the different soils is different. If the soil is too thick, the seedlings will be slow, or the seeds will be smashed without emergence. If the soil is too shallow, it may cause the seed to be unearthed and affect the quality of the seedling. Specific covering principle: the thickness of the covering soil is 3 to 5 times the diameter of the seed, the large seed is taken 3 times, and the small seed is taken 5 times. Generally, the small seed is covered with 0.5-1 cm of soil after sowing, and the large seed is covered with soil about 1-2 cm. Note: During the emergence of seeds, if there is a phenomenon of capping, immediately cover a layer of soil, increase the pressure of covering soil, and help the seed to shell. For seedlings unearthed with caps, water can be sprayed to soften the seed coat, and then artificially assisted to shell. Third, the method of sowing seedlings is fast and good 1, buy high-quality seeds, if the quality of the seeds is not good, then the emergence of seedlings is certainly uneven. 2, soaking seeds and then planting seedlings quickly and neatly. The vegetable seed is soaked after the seed soaking process, and if it is at a suitable temperature, it will germinate. Note that cabbage, Chinese cabbage, small rapeseed, etc. are particularly easy to emerge, and generally do not soak seeds. 3. For the vegetable seeds that are spread or broadcasted, the seeds can be evenly distributed after the seeding is completed. If the seedling tray is sown, the seedling trays can be picked up neatly and vertically, and then the top plate is gently pressed, so that the following 9 plates will have the same depth of soil, one seed per hole, and then the small board after covering the soil. It can be scraped, flat and even. In fact, in the process of vegetable cultivation, the problem of emergence is very important, but it is easier to solve. Generally, 3-5 days after sowing, seedlings can be emerged, while parsley, lettuce, celery, etc. take 7-10 days to emerge. Everyone just needs to deal with it before sowing, and wait patiently in the later stage.
