Bigen fruit, also known as American hickory, longevity fruit, longevity fruit, etc., is a tree plant of the genus Carya in the walnut family, native to the United States and northern Mexico of the North American continent, and has now become one of the worldwide dry fruit species. Hebei, Henan, Jiangsu, Zhejiang, Fujian, Jiangxi, Hunan, Sichuan and other places in China are cultivated. Let's take a look at the price and planting method of Bigen fruit seedlings.

How much is a Bigen fruit tree seedling?

The price of Bigen fruit tree seedlings is about 10-12 yuan, which is available in Jiangsu, Zhejiang, Shandong, Henan and other places, but the price varies greatly due to the specification, market and quantity of the seedlings. The green root fruit is generally sown and raised seedlings in the first year, grafted in the spring of the second year, transplanted in autumn and winter in the second year, and can emerge in autumn and winter in the third year. The seedlings begin to hang fruit about three years after planting, and can achieve high yield in five years. The flowering period is from April to May and the fruit period is from July to November.

Planting conditions of Radix Rehmanniae

1. Temperature: Bigenguo prefers warm and humid climate, the annual average temperature is 15.2℃, the highest temperature is 41.7℃, it is cold-resistant, and it is not damaged by freezing at-15 ℃, but low temperature at flowering stage will affect flowering, pollination and flower development.

2. Moisture: Bigen fruit has different water requirements in different phenological periods of the year, proper amount of Rain Water is required in spring shoot growth period before flowering, continuous overcast and rain is avoided in flowering period, and sufficient and uniform rainfall is required in fruit and naked bud development period.

3. Light: the green root fruit is not too demanding on the light, and the young period requires a cool environment, so the seedlings should be shaded artificially, and the adult trees do not grow well on the sunny and barren sunny slope.

4. Soil: oil-black soil, yellow soil developed on limestone and yellow soil developed on limestone, slate and shale are the best, while red soil and sandy soil are not suitable for planting.

The Propagation method of Bigen Fruit

1. Sowing: Bigen fruit can be sowed in spring and autumn, but autumn sowing is not as safe as spring sowing. Autumn sowing is usually finished before autumn soil freezes. Spring sowing should be early and can be sowed in mid-March, but the seeds must be treated with sand storage.

2. Grafting: the rootstock used for grafting is generally walnut. The scion is collected on a fine single plant, and the full buds in the middle and lower part of the scion with a length of 30 cm 40 cm in length and 1 cm in diameter and 1.5 cm in diameter are selected as buds.

3. Cuttage: 1-year-old strong branches are usually selected for cuttage propagation, the cuttings are 17-20 cm long, and the survival rate is usually more than 90% by common cutting method.

4. Root cutting: the cuttage of green root fruit is combined with the nursery to pick the root, and then the false planting is carried out in spring. The diameter of the seed root is 1 cm and the length is 10 cm. The upper cut of the root must be buried 0.5 cm below the bed.

5. Striping: during the dormant period, the sturdy branches of the mother plant are pressed into the soil and can take root after a period of time, and then the branches are separated from the mother plant, transplanted and cultured.

Planting method of Radix Rehmanniae

1. Soil preparation and fertilization: the green root fruit should be planted in the land with deep soil layer, loose, sufficient water source and leeward to the sun. after digging holes, put a layer of straw at the bottom of the pit, put in 50kg of organic fertilizer, 20g of methamphetamine powder, 500g of calcium superphosphate and mix well with the soil.

2. Transplanting: Bigen fruit transplant is carried out after defoliation or before germination, large seedlings with mud balls, 1-and 2-year-old seedlings should leave more lateral roots and fibrous roots and dip in mud in time, and measures such as burying soil and cultivating soil pile should be taken during the young tree stage, especially before winter in the planting year.

3. Pruning: early pruning of Bigen fruit should be light, leaving more main branches to make it bear fruit early, the inner chamber of the crown should be ventilated and transparent during pruning, the upper branches of the crown should be kept as far as possible, and the lower part of the crown can be thinned step by step.

4. Intermediate ploughing and weeding: within 1-3 years after the establishment of the Bigen orchard, crops such as soybeans, corn and Atractylodes macrocephala Koidz can be intercropped. In the process of intercropping, the garden should be ploughed and weeded, and appropriate amounts of organic fertilizers such as coke ash, cake fertilizer and barnyard manure should be applied.

5. Fertilization and fruit protection: before the Bigen fruit germinates in spring, about 30 kg of urea is applied per mu, 80 kg of special fertilizer for fruit trees is applied during the fruit expansion period, and 3000 kg of base fertilizer is applied in autumn. After entering the fruiting period, fertilizer is applied according to the results.

6. pest control: the main diseases and insect pests of Bigen fruit are hickory branch blight, longicorn beetle, green caterpillar moth, coffee bark moth, etc. focus on orchard pest control in winter, timely prevention and control according to the occurrence of diseases and insect pests.
