Dogwood, also known as Dogwood, Tianmuzi, Zhenzao, etc. It is a deciduous tree or shrub of the Cornus family. After removing the pit from the ripe and dried fruit, the sweet potato meat is a precious medicinal material, which has the effect of nourishing the liver and kidneys and strengthening the kidney essence. It is suitable for aches and pains in the waist and knees, spermatorrhea, dizziness and tinnitus caused by liver and kidney deficiency. Let’s take a look at dogwood seed prices and planting methods!
How much does a pound of dogwood seeds cost?
The price of dogwood seeds is about 30 yuan for 20 to 1 kilogram, but there are differences due to seed quality, variety, origin, market and other reasons. Dogwood is a positive tree species in the warm temperate zone. The suitable temperature is 20 to 30 degrees Celsius. It has strong cold resistance and can tolerate short-term low temperatures of -18 degrees Celsius. It is shade-tolerant but has sufficient sunshine. It should be planted in sandy loam soil with good drainage and rich organic matter. Propagation methods include sowing, layering, cuttings, grafting, etc. In production, seed propagation and grafting are mainly used. The amount of seeds used for sowing and propagation is 0.9~1.0 grains.
How to sow dogwood
1. Land preparation and fertilization: Before sowing, the dogwood nursery land must be deeply plowed, leveled, and thinned to ensure that it is loose, crushed, flat, rootless, and stone-free. There are no tiles, and the plowing depth is more than 20cm. It is important to combine the application of retted farmyard manure with deep plowing.
2. Seed collection: Dogwood seeds should be selected from high-quality mother trees with vigorous growth, high fruiting period and no vintage. From September to October, pick fully mature fruits with large and plump seeds, no pests and diseases, no damage, and deep red color. Remove the pulp from the picked fruits.
3. Seed treatment: Rub dogwood seeds with 5 alkaline water for 5 minutes, then scald with boiling water, stir while pouring boiling water, rub for 5 minutes when the water is slightly cold, soak in cold water for 24 hours, and then take out Dry for 8 hours and repeat for at least 3 days. When the 90% seed shell has cracks, mix it with wet sand and hide it in the sand.
4. Sowing method: Spring sowing and raising of dogwood seedlings is carried out before and after the vernal equinox. Before sowing, make a shallow trench about 5 cm deep in the border with a row spacing of 30 cm. Spread the seeds evenly in the ditch, cover with 3-4 cm of soil, and keep the soil moist. Seedlings can emerge in 40-50 days.
How to plant dogwood
1. Planting density: 30 to 50 dogwood plants should be planted per acre. If intercropped with other shrubs or trees, only about 20 can be planted. It is better to arrange squares for all departments. Cultivated land with good conditions should be sparse, while cultivated land with poor conditions can be densely populated.
2. Planting period: Dogwood is planted during the dormant period, when the temperature and humidity gradually rise, which is the most suitable planting period, generally from December to January of the following year. After January, the transplant survival rate dropped significantly.
3. Planting method: Pick plum seedlings on cloudy days and cover the roots of the seedlings with soil. Before planting, the roots should be trimmed and dipped in mud to protect the seedlings from damage. The roots should not be exposed to the sun or wind. In the prepared planting holes, apply 2 kg of manure per hole and mix it with the soil.
Management techniques of dogwood
1. Expanding the hole and cultivating the soil: After planting the dogwood, you should promptly expand the hole and cultivate the soil, enlarge the tree tray, fertilize the soil, and create favorable soil conditions for the root system. , increase the scope of nutrient absorption. In the first few years of the growth of saplings, the soil should be expanded to a depth of 30~40cm outside the planting hole.
2. Reasonable interplanting: After 3 to 4 years of planting dogwood, dwarf crops, green manure crops, or other herbs can be interplanted between the rows, but the density should not be too high.
3. Cultivating and weeding: In the first three years after dogwood planting, cultivating and weeding can be carried out 2 to 3 times a year depending on the situation. Comprehensive garden plots can be combined with intercrops. Be careful not to damage saplings and roots during operation.
4. Timely fertilization: Dogwood should be fertilized at the appropriate time
7. Reasonable irrigation: After planting dogwood, when the tree is blooming and young fruit, or when the weather is dry in summer and autumn, timely fertilization should be carried out. Water and keep the soil moist to ensure the survival of seedlings and prevent drought, flower and fruit drop, resulting in reduced yields.
Dogwood pest control
1. Keratosis: Keratosis damages the leaves. Before germination in spring, remove fallen leaves from under trees to reduce the source of infection. Starting from June, spray 1:100 Bordeaux mixture once a month and three times a month, or spray 400 to 500 times of zinc.
2. Anthracnose: Anthracnose damages fruits, with black and semi-black fruits appearing in mid-June. In the early stage, spray Bordeaux mixture at a ratio of 1:1:100, and spray 50% carbendazim solution 800 to 1,000 times in the middle of each month.
3. *** Diseases: *** diseases damage the leaves. During prevention and treatment, reasonable and dense planting should be done to ensure that the forest is ventilated and the plants are strong. In the early stage of the disease, spray 50 thiophanate 1000 times.
3. Fruit-boring moth: Fruit-boring moth eats fruit pulp. During the adult emergence period, 2.5 deltamethrin 5000-8000 times solution or 20 fenvalerate 2000-4000 times solution can be sprayed for control.
4. Moths: Moth larvae bite the leaves. During the emergence period, you can spray 10 pyrethroids 2000-3000 times, 90 trichlorfon 800-1000 times, or 40 omethoate 1000 times.
5. Diamondback moth: Diamondback moth larvae bite leaves. In July, 1 to 2-year-old saplings should be sprayed with 500-600 times of 2.5 Rotana or 1000 times of Trichlorfon 90 in a timely manner for control.
6. Cicada: Adult cicada sucks branches and leaves, spray with 50 phosphoramide emulsion 2000 times, 40 dimethoate 600 times or pyrethroid 5000~8000 times.
7. American white moth: The young larvae of American white moth gnaw on the leaf mesophy, and the old larvae gnaw along the leaf edges. In the larval stage, spray deltamethrin 5000~8000 times, 90 trichlorfon 800 times or 80 dichlorvos 1000 times, and 50 malathion 1500 times.
8. Bag moth: Spray 400 times of 50th phosphorus emulsion on the trunk to kill newly hatched larvae. When the larvae are bored into the xylem, inject 40 dimethoate 50 times or 80 dichlorvos 50 times into the wormhole and seal it with clay.
9. Scale insects: You can spray 501605 EC1500 times solution or 40 Omethoate EC1000 times solution in the nymph stage, spray once every 7-10 days, 3 times, or drill holes at the base of the tree. Spray 40 omethoate.
