Generally speaking, you must first prepare seedling trays and seedling substrates of appropriate specifications, and thoroughly disinfect and clean the germs and debris in the nursery site. In addition, the seedling trays and seedling raising substrates need to be disinfected to prevent the seeds from getting sick, or ultimately prevent the cantaloupe seedlings from being infected by pathogens due to bacteria in the trays or in the seedling raising substrate. If this is the case, it can be said that the process of raising cantaloupe seedlings in the later stage will be very troublesome. For the prevention of pathogens, it is necessary to ensure that the seedlings are healthy and strong when raising cantaloupe seedlings, so that the management of such seedlings during the growth of cantaloupe plants is the best.
Hami melon plug trays generally use 72-hole specifications, and coconut bran is used for seedling cultivation. Chemical disinfection and hot water disinfection are commonly used for disinfection of seedling substrates. When disinfecting with hot water, basically soak and disinfect the seedling tray and seedling substrate with boiling water at about 70-80°C, and then put the seedling substrate into the plug tray. Chemical disinfection basically prevents bacterial and fungal diseases and basically mixes bacterial and fungal agents for disinfection. Common pharmaceuticals, such as chlorothalonil, are basically produced using these pharmaceuticals, and the effects are also good. Generally speaking, cantaloupe seeds need to be disinfected before germination.
There are many ways to sterilize seeds, but the most commonly used method in China is to use warm water to sterilize seeds. The reason is to remove germs on the surface of the seed shell, so the seeds need to be soaked before sowing. General germination steps can be divided into the following steps: (1) First, put the seeds into warm water at 55°C, continue stirring until the temperature drops to about 30°C, and then stop stirring. (2) Soak the seeds in water at 30°C for half a day. (3) Then wrap the seeds with gauze and put them in an incubator, keeping the temperature at about 30°C. 4. Finally, wait for about 24 hours, you can see the germs of the seeds exposed, and you can put the seeds into the seedling tray. Generally, when sowing, put the seedling cultivation substrate into the seedling cultivation tray, press holes on the top of the seedling cultivation tray, and then sow seeds. Immediately after sowing, cover the holes with coconut bran and then water. Generally, for sowing, you can basically stop watering after watering on the same day, but you can basically check the moisture content of the substrate every day and replenish water after it breaks out. Of course, before breaking the soil, the moisture content of the seedling substrate should also be observed every day. If it is found to be too dry, water it immediately.
