Can black wolfberries be grown on the Jiaodong Peninsula

Goji berries are very adaptable and can tolerate 38High temperature of 5 degrees Celsius, cold tolerance is also very strong, at - 25It has no frost damage at 6 degrees Celsius, is drought tolerant, and can still grow in desert land.

It is a light-loving tree species, which grows vigorously in full light, and grows weakly in the shade, with very few flowers and fruits. The soil requirements are not strict, and the soil salt content of the background soil 0 10 cm soil layer can reach 89%, 10 30 cm soil layer soil salt content up to 5

1%, the salt content of rhizosphere soil soil is 25%, it can be seen that it has strong salt and alkali tolerance and strong salt absorption ability; The waterlogging resistance is poor, and low-lying waterlogged places are not suitable for planting. It is found in various salinized habitat soils such as saline-alkali wasteland, salinized sandy land, salt lake shores, canals and roads, and river beaches.

1. The cultivation density is recommended to be 150 plants per mu of black wolfberry. It can be cultivated reasonably according to the row spacing of 3 meters and the plant spacing of meters, which does not affect the growth of black wolfberry and the picking of fruits, and does not waste land resources.

2. Field management: throughout the year, it is necessary to combine hoeing, loosen the soil in time, water moderately according to the land conditions, apply sufficient base fertilizer in March every year, and carry out scientific top dressing at the end of June and August. In the early stage, nitrogen fertilizer was the main fertilizer, and more phosphorus fertilizer and potassium fertilizer were applied in the later stage.

3. Shaping and pruning:

The black wolfberry bears fruit in the same year, and enters the full fruiting period in four to five years, and its shaping must be completed three years before planting. In the year of planting, all branches should be shortened at a height of about 30-40 cm, leaving 4-5 well-developed main branches, which is the first layer, and then leaving a layer every 30-40 cm, leaving 3-5 main branches in each layer, and finally pruning the whole tree into a three-to-four-layer umbrella-like form, on this basis, it will be properly pruned and shaped every year. After such pruning and shaping, each black wolfberry can have dozens of fruiting backbone branches, which can relatively maintain the yield.

Pruning is important to increase yields and cultivate Goji barbarum.

4. Harvesting and processing: The harvesting of black wolfberry should be between the planting of mango and the autumn equinox. Pick ripe fruits in time, dry them in the shade or dry, and should not be exposed to the sun to avoid excessive drying, and be careful not to knead them by hand so as not to affect the quality. In summer, when it rains, it can be dried over a warm fire.

The Jiaodong Peninsula can be planted with black wolfberry, the adaptability of black wolfberry is still very strong, I am in Hebei, and the black wolfberry planted at home has borne fruit.

It is a unique desert medicinal plant species in western China, which is distributed in alpine sandforests, salinized sandy lands, rivers and lakes, dry riverbeds and desert riparian forests. Wild wolfberry is very adaptable, can tolerate high temperatures Celsius, is also very cold-tolerant, has no frost damage at --Celsius, is drought tolerant, and can still grow in desert land. It is a light-loving tree species, which grows vigorously in full light, and grows weakly in the shade, with very few flowers and fruits.

The requirements for soil are not strict, and it is resistant to salinity and drought.

Black wolfberry is black fruit wolfberry. The name of the black fruit wolfberry is "Qiaonuoying-Halmag", and the name of Tibetan medicine is "Punma", which belongs to the genus Solanaceae. It is a spiny shrub, multi-branched, with hard branches, often zigzag-shaped, curved, and white.

It is distributed in Qinghai, Xinjiang, Gansu and other places in China and Europe and Central Asia.

In Qinhuangdao, Hebei Province, the most suitable growth environment for black wolfberry is as follows: the average annual temperature is -1-5 degrees, the annual precipitation is 40-400mm, the less precipitation, the greater the temperature difference between day and night, and the higher the anthocyanin content.

Cultivation method: 1) Seed collection, seed preparation and seed storageThe collection period of black fruit wolfberry is from July to November, when the fruit turns from green to purple and black, it should be picked in time, and then registered and transported to the designated place. After seed collection, the seeds are washed and threshed by gauze wrapping water, and then filtered and washed with a fine basket.

Drying should be cooled or sun-dried in the morning and evening, and avoid exposure. The net seed method is artificial. After the seeds are prepared, they are stored in a dry and aerated place with fiber bags.

2) Determination of seed qualityIn addition to investigating whether the seed is excellent, it is also necessary to check the clarity, 1000-grain quality, germination rate, vitality, fineness, water content and weight of the seed. The main thing is to check and determine the germination rate of the seeds. The method was determined by laboratory sample germination method.

Seed quality is judged according to the appearance and internal anatomical condition of the seed.

3) The propagation method is mainly propagated by seeds, and can also be propagated by cuttings and root tillers.

4) Root tiller seedling propagationIn the spring, the root tiller seedlings around the mother plant are dug up and returned to the nursery for cultivation.

Field management. Cultivating and weeding: After the seeds emerge, the soil should be loosened and weeded, 4 to 6 times within 1 year, combined with irrigation to loosen the soil and weed.

Irrigation: Timely irrigation according to soil moisture, generally 4 6 times in 1 year.

Seedlings: In June, when the seedlings are 3 5cm high, the seedlings are weak and too dense. Around mid-July, the seedlings were fixed, and the distance between the seedlings was 10 15cm.

Top dressing: Combined with irrigation, top dressing of fast-acting nitrogen fertilizer 1 2 times in mid to late June, and top dressing of sock wheels 1 time in mid to late July.

Pest control: insect pests include aphids, wolfberry negative mud worms, wolfberry powdery mildew, soot disease, etc., which can be sprayed with 40% dimethoate, liquid medicine and carbendazim.
