Let's look at the seed price and planting method of Toona sinensis.

How much is the seed of Toona sinensis per jin?

The price of Toona sinensis seed is about 3040 yuan per jin, but it varies greatly due to seed quality (budding rate), variety, producing area and market. There are many varieties of Toona sinensis. According to the different colors of budding buds and cotyledons of Toona sinensis, it can be divided into two categories: purple Toona sinensis and green Toona sinensis. The varieties of purple Toona sinensis are black oil Toona sinensis, red oil Toona sinensis, Jiaozuo red Toona sinensis, Ximou Toona sinensis and so on.

Sowing method of Toona sinensis

The main results are as follows: 1. Seed collection: Toona sinensis blossoms from May to June, the fruit matures from October to November, and the fruit is reddish brown when it is mature. 15-30-year-old tall and robust mother trees should be selected to collect seeds, dry and clean seeds weigh 15 grams, and the germination rate is 40-50%.

2. Soaking seeds in heat preservation: the seeds of Toona sinensis were soaked in warm water of 40 ℃ for about 5 minutes, stirred continuously, and then soaked in water of 20: 30 ℃ for 24 hours. After absorbing enough water, the seeds were removed, and the excess water was controlled to accelerate germination.

3. Moisturizing and sprouting: Toona sinensis seeds stand 3 cm thick and then covered with a clean cloth, moisturizing and germinating under the environment of 20: 25 ℃. During the budding period, turn twice a day and rinse 2 times with 25 ℃ water for 2 times. 30% of the seeds can be sown when they sprout.

4. sowing at the right time: Toona sinensis selects sandy soil and fertile soil with flat terrain, sufficient light and good drainage as seedling land, combined with soil preparation and fertilization, spread evenly, turn through, and sow the budding seeds evenly, covering 2 cm thick soil.

5. Seedling management: Toona sinensis seeds emerged about 7 days after sowing, and watering was strictly controlled before emergence to prevent soil consolidation from affecting seedling emergence. When seedlings were unearthed and grew 4-6 true leaves, seedlings should be interspersed and fixed.

Planting method of Toona sinensis

1. Soil preparation and fertilization: in the cultivation of Toona sinensis in solar greenhouse, sufficient base fertilizer must be applied, not less than 5000 kg of high-quality farm manure, not less than 100kg of calcium superphosphate and 25kg of urea per mu, spread evenly and turn deeply, and then plant seedlings on the whole border, generally 80cm wide.

2. Planting density: the planting density of Toona sinensis is about 30,000 plants per mu with a spacing of 15 cm and a row spacing of 15 cm, and the dwarfing treatment of seedlings is carried out when the plant height is about 50 cm.

3. Temperature management: Toona sinensis can not be heated in the first few days, keeping the temperature at 1 ℃ ~ 5 ℃ to slow down the seedlings. After 8-10 days of planting, the greenhouse was covered with grass grass, so that the temperature in the greenhouse was controlled at 18-24 ℃ during the day and 12-14 ℃ at night.

4. Hormone regulation: after planting slow seedlings, Toona sinensis was treated with Paozhibao. 4% of the 5 dormant buds in the upper part of Toona sinensis seedlings were treated with Baizhibao. 1 gram of medicine was coated with 100 buds, which could make the buds full and strong, and the yield could be increased by 10%.

5. humidity regulation: Toona sinensis seedlings planted in the greenhouse should maintain a high humidity, pour water thoroughly after planting, and then pour small water according to the situation, the air relative humidity should be kept at about 85%, and the relative humidity during the growth period after germination should be about 70%.

6. Light regulation: the growth of Toona sinensis can be promoted by better light in solar greenhouse, no dripping film is used, and the greenhouse film is kept clean. The number of branches can be increased by paclobutrazol treatment combined with coring.

7. Harvest of Toona sinensis buds: Toona sinensis buds grow to 15cm and start harvesting when they are well colored. Harvest should be carried out in the morning and evening. Toona sinensis buds can be picked once every 7 to 10 days in the greenhouse for a total of 4 times. After each bud is picked, it is necessary to fertilize and water them.
