Toona sinensis sprout seedling cultivation methods and technical key points
Toona sinensis sprout seedlings are the seedlings of Toona sinensis, edible, and the taste is very tender and delicious, with diversified eating methods, deeply loved by food lovers. Cultivating Toona sinensis sprout seedlings requires mastering certain methods and techniques. Below, the editor will popularize the Toona sinensis sprout seedling cultivation techniques for everyone.
Cultivation of Toona sinensis sprout seedlings
1. Germination promotion. Remove impurities from the Toona sinensis seeds of the current year, wash them clean, soak them in warm water at 30°C for about 12 hours, then filter out the water, cover them well with a wet cloth, and keep the temperature at about 25 to 30°C. Generally, after 3 to 4 days, the Toona sinensis sprouts begin to germinate. During this period, the seeds and the covering cloth should be rinsed once a day with warm water to keep them clean.
2. Seedling tray preparation. The seedling tray should be washed clean, and a layer of paper can be placed at the bottom of the tray. Spread a layer of about 2.5 to 3cm of moist perlite on the paper.
3. Sowing. The Toona sinensis seeds that have been treated for germination promotion should be evenly broadcast on the substrate. Cover the seeds with a 1.5cm thick layer of perlite, and after covering, spray water with a sprayer.
4. Management. After sowing Toona sinensis, it is best to place the seedling tray on a rack, and keep the temperature at about 20°C. About 5 days after sowing, they will sprout and grow out of the substrate surface. Generally, in 10 days they can grow to about 8cm. During this period, attention should be paid to regular spraying to keep the relative air humidity at about 80%, which can promote the growth of Toona sinensis seed sprouts and make them tender.
5. Harvesting. About two weeks after sowing, when the hypocotyl of the seed sprouts is more than 10cm, has not yet become lignified, and the cotyledons have unfolded, they should be harvested. When harvesting, pull the Toona sinensis seed sprouts out from the substrate together with the roots, wash them clean, and they are ready.
Toona sinensis seedling vegetable
Toona sinensis seedling vegetable is the edible Toona sinensis seedling obtained by continuing to expose it to light on the basis of cultivating Toona sinensis seed sprout vegetable. When the Toona sinensis seed sprout vegetable has grown thick, yellow and tender, and the cotyledons have fully unfolded, it can continue to grow with light exposure for greening. Toona sinensis seedling vegetable grows well under weak light and scattered light conditions, and can be regulated according to weather conditions using shade nets. Before harvesting, turn the trays upside down, left and right, and front and back according to the seedling color. Generally, after 2 to 3 days of light exposure, when the seedlings have grown to more than 10 cm, the cotyledons have fully unfolded, and the true leaves have appeared, harvest and market them before they become lignified.
Seed selection and purchase
For seed selection, choose red-oil Toona sinensis seeds of the current year, requiring uniform size, plump grains, and a germination rate of more than 95%. When Toona sinensis seeds are stored improperly or the seed quality is poor, the germination rate will decrease significantly. Therefore, when purchasing seeds, be sure to buy fresh seeds harvested in the current year. New seeds should be stored at room temperature from November to March of the following year, and in other seasons they must be stored under low-temperature conditions of (1-5)°C. During seed storage, pay attention to protecting the wing membrane of the seeds to ensure the germination rate of the seeds.
Growth period management
1. Temperature. Suitable temperature is the foundation for the robust growth of Toona sinensis, and the growth temperature of Toona sinensis is 20 to 30°C. The maximum temperature cannot exceed 35°C, and the minimum temperature cannot be lower than 15°C. If the temperature is too high, it tends to promote growth but the sprouts become thin and weak, with poor flavor. If the temperature is too low, growth is slow. When the indoor temperature drops to 5°C or 3°C, growth stops. Therefore, during cultivation, the temperature must be controlled to promote robust growth and improve quality and yield.
2. Light. After the seeds germinate and the plants grow to 5 to 6 cm high, weak light should be provided. It is best to use a shade net to reduce direct light. When the seedlings are 7 to 8 cm high, gradually increase the light. Except for summer high temperatures that require shade nets for cooling, generally no shading is needed, so that the whole plant has relatively sufficient light (especially scattered light). Good light conditions can increase the chlorophyll content of Toona sinensis seedlings, making the color bright and glossy and the flavor rich.
3. Humidity. The relative air humidity in the indoor cultivation of Toona sinensis is required to be about 80%. If it is lower than 80%, the seed coat is not easy to fall off, and if it exceeds 80%, it is easy to cause root rot and seedling rot.
4. Water management. After being placed on the rack, according to weather conditions, water 2 to 3 times a day. The amount of water each time should not be too much, so that it is suitable to moisten the seeds, with no accumulated water in the tray and no dripping. When watering and after watering, appropriate ventilation should be carried out to reduce air humidity.
Through the above content, I believe everyone has gained a certain understanding of Toona sinensis sprout seedling cultivation. Although Toona sinensis sprouts grow very fast, be sure to harvest relatively tender sprout seedlings. If you wait until they are old before harvesting, the taste and nutrition are not as good as those of tender sprout seedlings! If you like to eat them, you can grow some at home, healthy and delicious!
