The latest course of planting techniques and methods of thorn buds

Thorn tender buds are called thorn sprouts, thorn Ravens, Aralia elata, tiger yang thorns, etc., born in forest margins, shrubs, forest clearings, buds are edible parts, and there are a variety of edible methods. can eat raw, fried food, sauce, soup, stuffing or processing into different flavor of pickles, for the famous first-class wild vegetables, known as the "king of wild vegetables", let's take a look at thorn bud planting technology!

Planting prospect of thorn buds

Thorn buds grow freely in the natural environment, do not require high environmental conditions, high seed reproduction rate, fast growth and low cost, without any risk, and the operation process is easy to master. Artificial cultivation is still in its infancy, the resources are reduced, the social demand is increasing, and there is a huge domestic and international market. A plate of thorn buds in high-end hotels is worth hundreds of yuan. However, due to the continuous collection, the plants withered, the wild resources were destroyed year by year, the yield decreased year by year, and the yield could not meet the needs of the market, so it is a top priority to develop artificial production of thorn buds. Therefore, artificial cultivation of thorn buds has a very broad development prospect.

Planting benefit of thorn bud

1. Yield: two thorn buds per square meter are planted artificially. Through artificial domestication, the yield of each plant can reach 0.5-1.5 kg. According to the calculation of large mu, 2000 plants per mu can reach about 1.5 tons.

2, benefit: thorn tender buds are very rich in nutrients, and the amount of natural wild is very small, the international market price is about 5000 million yuan per ton, and the economic income per mu can reach about 75000 yuan 15000 yuan.

Raising seedlings with prickly bud seeds

1. Raising seedlings in open field: the bed can be made in autumn or spring, flat land can be loosened and turned fine, 300kg of rotten farm manure per mu, 50kg of nitrogen, phosphorus and potassium compound fertilizer combined with soil preparation can be applied at one time, and then make the bed, the bed is 1.2m wide and 10cm high. Sow seeds after finishing the bed, and the sowing time is set at the end of March to Ching Ming Festival. The seeds of thorn buds are very small. In order to improve the sowing quality and make it uniform, fine sand should be mixed with 10-15 kg per mu.

2. Pot plate seedling raising: plastic bowl plate is used to raise seedlings in advance in the greenhouse, and the time can be set at about 2 months before transplantation. the matrix can use crushed peat to add a small amount of mature high-quality farm fertilizer and compound fertilizer, in order to increase viscosity, a small amount of yellow mud needs to be added to the substrate. When sowing, fill the bowl with 3x4 deep matrix, and after watering, sow the treated seeds. For the sake of safety, it is best to sow an average of 1520 seeds per hole. After sowing the seeds, cover them with a thin layer of matrix or mountain skin soil, and cover the top with a thin layer of vermiculite powder.

Planting technique of thorn bud

1. Planting time: the seedlings of spiny buds can be planted when the stems grow to more than 10 centimeters and produce many needles. The seedlings must be planted after the seedlings are ventilated and controlled by water. Generally, when the ground temperature of 10 centimeters is above 12 ℃ in early spring, the method is the same as planting trees.

2. Planting density: the root system of thorn buds is developed, branches and leaves are luxuriant, if the row spacing is too narrow, it is bound to affect ventilation and light transmission, resulting in excessive stem growth. Planting one plant per square meter is more reasonable, the row spacing can be appropriately wider, and the best design method is 1.8 meters between rows and 0.6 meters between plants, so that 700 holes can be planted per mu.

Planting management of thorn buds

1. Weed control: in the first year, it is easy to be attacked by weeds, and the herbicides used in general legume crops are more effective, but which pesticide is the most effective in weeding needs to be further tested. If artificial weeding is adopted, then care must be taken not to harm the root system in the process of weeding. After summer, thorn buds have grown to a certain height, branches and leaves are also luxuriant, when the threat of weeds can be laissez-faire.

2. Water management: the main purpose of water management is to prevent spring drought, and the land for breeding stems needs to be closer to the water source. Once the drought occurs, it should be watered immediately to ensure that the seedlings are strong. In addition, although thorn tender sprouts like water, they are not resistant to waterlogging, so in the event of floods and floods, ditches should be dug around the land immediately to alleviate the disaster.

3. Pruning: pruning the tender buds makes the plant height suitable for harvesting, promoting the development of multiple branches and roots, increasing the yield, pruning close to the base of the branches, leaving 4 or 6 lateral buds, and cutting off the upper part. Pruning is completed before sap flow in early spring, and the growing period can be carried out after harvest.

4. Reasonable topdressing: when planting thorn buds, topdressing should be carried out properly according to soil fertility and growth potential, farm manure and chemical fertilizer can be applied directly on the border, ridge or hole, and chemical fertilizer can be applied to cover the soil.

5. Timely harvest: after the prickly tender buds break off the terminal buds, the 1-5 lateral buds in the lower part of the terminal buds or the accessory buds of the terminal buds germinate, so they can be picked many times, preferably 2-3 times, not many times, so as not to accumulate trees, the tender buds are 10-15 cm, and the leaves have not yet been unfolded, and the lateral bud leaves expand early and can be picked at 5-10 cm.
