Guangdong black skin winter melon sowing seedlings

Spring cultivation of winter melon, as often affected by low temperatures, it is appropriate to take the nutrient bowl seedlings. The required nutrient soil should be prepared in advance, can choose to bake and sieve the fertile garden soil, rotting pig, cow dung residue, husk ash or coconut husk and other mixed and become. Three volume ratio of about 6: 2: 2, plus a small amount of nitrogen, phosphorus and potassium composite fertilizer, the amount of its accession is generally controlled at 0.2% -0.3% is appropriate, and asked to get fine mixed evenly, in order to prevent injuries to the seeds and roots. Winter melon seed germination is generally 50-55 ℃ warm water first immersed in 10-15 minutes (while immersed and stirred), and then, and then continue to soak at room temperature for 10-12 hours, preferably, placed at a temperature of about 30 ℃ germination. Soak the seeds for a longer time, germination faster, more neat, a day and a half to two days, most of the germination; soak the seeds for a shorter period of time, the germination potential is poor. Seed skin smooth without edge of the seed, due to the seed to poor permeability, germination is easy to cause hypoxia rotten seed, germination rate is low. Therefore, the germination of such seeds, must first use fine sand to scrub the seed coat, remove adherents, and placed in 28-30 ℃ under constant temperature germination. Before germination, every morning and evening respectively, rinse the seeds with water 1 time, and timely filtering of water, and then continue to germinate. If there is no thermostatic equipment, it is advisable to take a dip in the Sichuan after direct broadcast to the seedling bag or seedbed is safer.
