Small bud method After the nutrient is loaded onto the nutrient soil, the water is poured, and the germinated seeds are placed flat in the center of the nutrient bowl. One seed is placed in each nutrient, and the soil is covered from 1 cm to 1.5 cm after sowing. In order to emerge early, the geothermal line is often laid under the nutrient squat in the winter and spring seasons, and the plastic film is covered on the top, and the film is removed when the bud is topped. The nutrient clods should be drenched before sowing, otherwise the root length will be directly affected. Seedling method Fill the seedling tray with ash, sand, sawdust, etc., and then pour the water, and place the germinated seeds evenly in the nursery tray with 1 cm thick sand. After sowing in winter and spring, put the seedling tray on the geothermal line, covered with plastic film, so as to keep warm and moisturize, but don't stick the film and sand too tightly, so as to avoid the shortage of oxygen supply, it can be placed under the shade in the summer. And pay attention to the moistness of the nutrient soil. Keep the temperature of 25 ° C to 30 ° C day and night, and remove the plastic film covering the seedling tray immediately after emergence from 24 hours to 36 hours. When about 80% of the seeds are ground and emerged, the temperature should be appropriately lowered, 20 ° C to 25 ° C during the day and 13 ° C to 16 ° C during the night to prevent the high temperature from causing the seedlings to grow. In order to prevent the emergence of cucumber "wearing caps", attention should be paid to placing the seeds flat on the nutrient soil when planting. Do not put the seeds on the nutrient soil, press gently to make the seeds in close contact with the nutrient soil, cover the soil 1 cm to 1.5 cm thick, can also be properly thickened with a light substrate. When the cotyledon is unearthed to the true leaf, the hypocotyl is the most prolonged period. The ground temperature and temperature should be lowered immediately after the cotyledon is unearthed, and the ground temperature drops to about 18 °C. Increase the light during the day to make the cotyledons green as soon as possible. If the daylight is weak and the night heat is high, it will not only aggravate the length, but also easily lead to the occurrence and spread of the disease. 2023 New Laser Distance Sensor
