Seed price and planting method of Cornus officinalis

Cornus officinalis, also known as Cornus meat, Tianmu seed, jujube, etc., is a deciduous tree or shrub of Cornaceae. After enucleation of ripe and dried fruit, it is a precious medicinal potato meat, which has the effect of nourishing liver and kidney and strengthening kidney astringent essence. It is suitable for the disease of sore waist and knee, spermatorrhea and vertigo caused by deficiency of liver and kidney. Let's take a look at the seed price and planting method of Cornus officinalis.

How much is the seed of dogwood per jin?

The price of dogwood seeds is about 20-30 yuan per jin, but it varies according to the quality, variety, origin and market of the seeds. Cornus officinalis is a positive tree species in warm temperate zone, with a suitable temperature of 20: 30 ℃, strong cold resistance, short-18 ℃ low temperature, shade tolerance but sufficient light, and should be planted in sandy soil with good drainage, rich organic matter and fertile sandy soil. the propagation methods are sowing, striping, cutting, grafting and so on.

Sowing method of Cornus officinalis

1. Soil preparation and fertilization: before sowing, the seedling land of Cornus officinalis must be deeply ploughed, leveled and trimmed to ensure looseness, fine crushing, leveling, no roots, no stone tiles, and the depth of ploughing is more than 20 centimeters. it is important to combine deep ploughing with retting farm manure.

2. Seed collection: the seeds of Cornus officinalis should choose excellent mother trees with strong growth, peak fruiting stage and no big or small years. From September to October, the fruits that are fully mature, large and full, disease-free, pest-free, damage-free and dark red should be picked, and the flesh of the picked fruit should be removed.

3. Seed treatment: the seeds of Cornus officinalis were rubbed with 5% alkaline water for 5 minutes, then scalded with boiling water, stirred with boiling water, rubbed for 5 minutes until the water was slightly cool, soaked in cold water for 24 hours, then dried for 8 hours, repeated for at least 3 days, and 90% of the seeds were stored after a crack in the shell was mixed with wet sand.

4. Sowing method: spring sowing and raising seedlings of Cornus officinalis were carried out before and after the Spring Equinox. Before sowing, a shallow ditch with a depth of about 5 cm was opened on the border according to a row spacing of 30 cm. The seeds were evenly scattered in the ditch, covered with soil 3-4 cm, and the soil was kept moist. Seedlings could emerge in 40-50 days.

Planting method of Cornus officinalis

1. Planting density: Cornus officinalis should plant 3050 trees per mu, if intercropping other shrubs or trees can only plant about 20 trees, the whole part should be arranged in a square, the cultivation land with good conditions should be sparse, and the cultivation land with poor conditions can be denser.

2. Planting period: Cornus officinalis is planted in the dormant period, when the temperature and moisture are in the stage of gradual rise, which is the most suitable planting period, generally from December to January of the following year, and the survival rate of transplanting decreases obviously after January.

3. Planting method: the seedlings of Fructus mandshurica should be planted on a cloudy day, and the roots should be trimmed and dipped in mud before planting to protect the seedlings from damage, and the roots should not be exposed to the sun or wind. 2 kg of barnyard manure should be mixed with the soil in each hole.

Management Technology of Cornus officinalis

1. Expanding holes to cultivate soil: after planting, Cornus officinalis should expand holes to cultivate soil, enlarge tree plates, mature soil, create good soil conditions for roots and increase the range of absorbing nutrients. In the first few years of the growth of young trees, hole expansion was carried out outside the planting hole with a depth of 30cm to 40cm.

2. Reasonable interplanting: 3-4 years after planting, dwarf crops, green manure crops or other herbal medicines can be interplanted with the gap between rows of Cornus officinalis, but the density should not be too high.

3. Intermediate ploughing and weeding: the first 3 years after planting of Cornus officinalis can be ploughed and weeded 2 or 3 times a year according to the situation. The fully arranged garden can be combined with interplanting crops, and care should be taken not to harm young trees and roots during operation.

4. timely fertilization: the fertilization of Cornus officinalis should be carried out appropriately and reasonably according to the growth habit and growth trend and the number of results, and pay attention to the combined application of organic fertilizer and chemical fertilizer, nitrogen, phosphorus and potassium fertilizer, soil fertilization and foliar spraying fertilizer.

5. Shaping and pruning: after planting, Cornus officinalis can adjust the tree shape, improve the utilization rate of space and light energy, adjust the balance between various parts of the tree, and achieve the purpose of early fruit, multi-fruit, stable yield and high quality, and increase economic benefits.

6. timely flower thinning: Cornus officinalis blossoms a lot and consumes more nutrients, so the fruit setting rate is reduced, and the phenomenon of big and small years appears. Therefore, in the fruiting year, in addition to heavy cutting in winter and controlling the amount of flowers, flower thinning can be carried out in March.

7. Rational irrigation: when Cornus officinalis is planted and in the flowering and young fruit stage of the tree, or when the weather is dry in summer and autumn, it is necessary to timely watering to keep the soil moist, to ensure the survival of seedlings and to prevent drought and fruit drop, resulting in reduced yield.

Prevention and control of diseases and insect pests of Cornus officinalis

1. Angular spot: the leaf is damaged by angular spot. The fallen leaves of the tree are removed before germination in spring to reduce the source of infection. In June, one hundred Bordeaux solution was sprayed once a month for a total of three times, or 400 to 500 times of Dysen zinc.

2. Anthrax: anthrax harms the fruit. Black fruit and semi-black fruit occur in mid-June. In the initial stage of the disease, 100 Bordeaux solution is sprayed, and 50% carbendazim is sprayed in the first and second half of each month.

3. Powdery mildew: powdery mildew is a harmful leaf, so it should be planted in a reasonable way to make the forest ventilated and transparent, so as to make the plant strong. In the early stage of the disease, 50% topiramate was sprayed 1000 times.

3. Fruit moth: the fruit moth eats the pulp and can be controlled by spraying 2.5% deltamethrin 5000-8000 times or 20% permethrin 2000-4000 times at the peak of adult Eclosion.

4. Big coir moth: the larva bites the leaves and can spray 10% permethrin 2000-3000 times or 80-1000 times of trichlorfon or 40% omethoate 1000 times during the occurrence period.

5. The wood-lifting inchworm: the larvae of the wood-lifting inchworm (bridge worm) bite the leaves, and the young trees of 1-year-old and 2-year-old should be sprayed with 2.5% fish rattan essence 500 times 600 times or 90% trichlorfon 1000 times in time in July.

6. Leafhopper: leafhopper adults suck twigs and leaves and spray them with 2000 times of 50% phosphoamine emulsion, 40% dimethoate or 5000-8000 times of pyrethroids.

7. Diamondback moth: the low-instar larvae of the diamondback moth gnawed on the mesophyll, while the older larvae mostly nibbled along the leaf edge. During the larval stage, deltamethrin was sprayed with 50008 000 times, 90% trichlorfon 800 times, or 80% dichlorvos 1000 times, 50% malathion 1500 times.

8. Spodoptera litura: during the newly hatched larvae, 50% parathion emulsion 400 times solution was sprayed to kill the larvae. When the larvae were eaten into the xylem, 40% dimethoate 50 times solution or 80% dichlorvos 50 times solution was injected into the wormhole and sealed with clay to kill the larvae.

9. Shell worms: during the nymph stage, 50% 1605 EC or 40% omethoate EC can be sprayed 1500 times or 40% omethoate EC 1000 times, once every 7 to 10 days, a total of 3 times, or 40% omethoate can be drilled at the base of the tree.
