Explain the wholesale price and planting technology of ginkgo seedling market in detail!

Ginkgo biloba is a common economic tree species in China, which is called "Gongsun tree" because it takes 20 years to bear fruit and 40 years to bear a lot of fruit. it has high ornamental value and medicinal value. at present, it has been widely planted in parks, greening places and other places. How much is the price of ginkgo seedlings? What are the planting techniques?

1. Introduction of ginkgo trees:

1. What is the name of the ginkgo tree?

Ginkgo tree, duck foot tree, Gongsun tree.

2. What are the characteristics of ginkgo trees?

The ginkgo tree is divided into four parts: root, stem, leaf and fruit, in which the bark of the young tree is smooth and light gray, the crown is conical, the big tree is grayish brown, the crown is wide ovate, and there are long spur-shaped short branches; the leaves are fan-shaped, light green on both sides and yellow before falling leaves in autumn. Flowers are dioecious, growing in the axils of scalelike leaves, showing clusters, and generally bloom in April. The seed is oval, oval, etc., the outer skin is white, there are 2 to 3 longitudinal edges, generally mature in October.

3. How big can the ginkgo tree grow in ten years?

Generally speaking, ginkgo trees with a diameter of about 5 cm 10 cm can grow 1 cm 2 cm a year, 11 cm 15 cm a year, and 16 cm 23 cm a year, so how big a ginkgo tree can grow in ten years depends on how thick it is before it can decide how much it can grow.

Second, how much is a ginkgo sapling?

Ginkgo biloba seedlings are divided into real seedlings and grafted seedlings, in which the seedling has a long life, exuberant vitality and strong resistance, so the price is relatively expensive, and the life span of grafted seedlings is also long, but the adaptability and resistance are relatively weak, so the price is relatively cheap, and the specific prices of real seedlings and grafted seedlings are as follows:

Name, specification, price, price, ~ 200 yuan 8 cm 80 cm 90 yuan 12 cm 250 cm 300 yuan 9 cm 100 cm 120 yuan 14 cm 400 cm 420 yuan 14 cm 400 cm 160 yuan 16 cm 500 cm 700 yuan 11 cm 180 cm 200 yuan 18 cm 800 cm 1000 yuan 12 cm 240 cm 280 yuan 20 cm 1800 cm 2200 yuan 13 cm 300 cm 350 yuan 22 2400 cm 3000 yuan 14 cm 450 500 550 yuan 24 cm 450 5000 yuan 15 cm 6505 000 yuan 26 cm 5507 000 yuan 26 cm 5500 7000 yuan 18 cm 1200 ~ 1200

Third, what are the planting methods of ginkgo trees?

1. Seed and seedling selection

Ginkgo tree has a long growth cycle and slow growth rate, so the seedlings with straight trunk, sturdy trunk and developed root system must be selected to improve the survival rate in the later stage.

2. Land selection and preparation

Ginkgo trees do not have high requirements for soil, as long as it is not saline-alkali soil or over-wet soil can be planted, so when selecting land, try to choose loose, fertile and good drainage of neutral or slightly acidic soil planting. After selecting the land, it is necessary to level the land and dig a field with a deep 60cm, a wide 60cm, a plant spacing of 2 to 3 meters and a row spacing of 3 to 4 meters, so as to facilitate the planting of seedlings in the later stage.

3. Planting

Before planting seedlings, it is best to sprinkle some base fertilizer on the soil, cover with a layer of 5cm thick fine soil, then put the ginkgo seedlings into the pit and fill them with soil, and finally water them again to allow them to grow slowly.

4. Field management technology

(1) Light requirements: ginkgo trees like light, so it is necessary to ensure sufficient light to promote plant photosynthesis and accelerate growth. If it is in a shady area, it is best to find a way to light, so as to prevent the plant from growing more and more fragile until death.

(2) Water requirements: ginkgo trees have higher water requirements, generally 3-4 days watering is the best, but do not irrigate too much, lest the humidity is too high and affect the plant growth. Especially in the rainy season, drainage measures should be taken to avoid stagnant water affecting plant growth.

(3) Fertilizer requirements: ginkgo trees do not have high requirements for fertilizer, generally applying organic fertilizer or farm manure twice a year. When fertilizing, try to use ring fertilization or hole fertilization to facilitate nutrient absorption.

For those who have been diseased, special agents can be used to control the disease.

(4.1) Stem rot: spray with 50% carbendazim wettable powder 200 times 300 times, once a week, 2 times 3 times in a row can be effectively prevented.

(4.2) Leaf blight: spraying with 50% carbendazim wettable powder 100 times or Bordeaux liquid powder, or brushing the wound with quicklime can be effectively prevented.

(4.3) Leaf mite: it can be sprayed with permethrin and fenpropathrin.

(4.4) Chilo suppressalis: 78% sperm killer soluble powder can be sprayed.
