Pretreatment before seed sowing

Although the seeds of some rare crops have obvious traits, strong adaptability, and rapid and easy germination, most of them need to be pre-treated before sowing, so that germination and emergence will be neat, and it will be easy to maintain seedlings, seedlings, and seedlings. Management employment.

One is the soaking method. That is, the seeds are soaked in cold or warm water (35°C to 40°C). After the seeds are inflated, they are laid flat on a shallow dish of wet gauze and then covered with several layers of wet gauze to ensure the required moisture during germination. The temperature is maintained. Around 25°C,

Rinse with cold water or warm water every day, and sow the seeds after germination. In general, thin seed coats can be soaked in cold water, and those with thick seed coats are soaked in warm water.

The second is broken shell method. For some seed coats, hard, impervious and impervious seeds need to be shell-cut. For example seeds of lotus seeds, pine needles, candied wax, cannas, oleander, and phoenix, etc., were inoculated with a sharp knife before seeding, or used a sharp knife to cut some of the seed coat, and then soaked in warm water for about 24 hours. The seeds are water-absorbent and can accelerate germination.

The third is the low temperature stratification method. For shells with oily, waxy seeds, such as magnolia, etc. can also be used to add water to form a paste paste seedlings, by the alkali of ash to remove wax, in order to facilitate the seed germination. Can also be used to soak seed plants, 0.5 kg of grass ash with 2.5 to 3.5 kg of boiling water shower, take the supernatant, until the temperature dropped to 40 °C when used to soak, soft soak the seeds after the hand rub, remove the oil, wax and then use After soaking in fresh water for a day and night, seed germination can be accelerated.
