Method for constructing pubescent angelica root vegetable plantation

Technical Field

The invention relates to a construction method of a pubescent angelica vegetable plantation, and belongs to the technical field of pubescent angelica.

Background

Radix Angelicae Pubescentis (Aralia cordia Thunb.) also called as edible native radix Angelicae sinensis is a plant used as both medicine and food, and is grown in the shade of forest or in hillside grass cluster at an altitude of 1300m-1600m, and is distributed in Japan. Du Huo is recorded in Shen nong Ben Cao Jing (Shen nong's herbal), listed as the first grade: the traditional Chinese medicine composition is mainly used for treating wind-cold attack, pain relief of incised wound, pain recovery from galloping, female sore slimming, weight loss after long-term taking and aging resistance. Radix Angelicae Pubescentis has effects of dispelling pathogenic wind, removing dampness, relieving pain, calming liver, calming endogenous wind, removing toxic substance, treating sore, tranquilizing mind, and stopping palpitation, and can be used for treating apoplexy, superficial infection, pyocutaneous disease, spasm, pruritus, palpitation, deficiency, conjunctival congestion, and swelling and pain.

In the past, the radix angelicae pubescentis mainly used for medicine, the harvesting amount is not large, and the number of wild radix angelicae pubescentis is enough. In recent years, with the improvement of living standard of common people, people pay more attention to the quality of life and also can select green vegetables which have fine, smooth, safe and pure mouthfeel. At present, tender stems and leaves of the wild pubescent angelica root also become a popular forest vegetable, and the wild pubescent angelica root is excessively harvested due to insufficient supply. High mountains with an altitude of 1300m or more are difficult to harvest and recover, and have great damage to biodiversity.

Wild radix Angelicae Pubescentis germinates in spring, and grows to 40-55 cm in height in about 4 months, which is the best harvesting period, and can be fried, dressed in sauce or pickled, such as dried bean curd fried with tender stem and leaf for invigorating qi, regulating the middle warmer, promoting fluid production, moistening dryness, and clearing away heat and toxic materials; for example, the chicken eggs fried by tender stems and leaves also have the effects of moistening lung, relieving sore throat, nourishing yin and the like. The pubescent angelica root dish has good taste, good quality and special fragrance, and is a slack season for the growth of other vegetables, so the pubescent angelica root dish is very popular.

The harvesting period of the wild pubescent angelica is from the middle and last ten days of 4 months to the last ten days of 5 months, and the tender stems of the wild pubescent angelica cultured in the full-sunlight mode in the periods or below the altitude of 1100m are quickly lignified, the fiber quantity is suddenly increased, the taste is poor, and the edible value is not high or the wild pubescent angelica cannot be eaten. The current situation severely restricts the development of the pubescent angelica root vegetable industry.

In view of this, it is necessary to develop and add a cultivation method for prolonging the harvesting period of pubescent angelica root and increasing the yield of pubescent angelica root, so as to solve the defects of the prior art.

The principle of the invention is introduced:

in the step 1.1 of the invention, seeds on a single plant of the radix angelicae pubescentis are collected generally and need to be stacked for 7d-9d, and the seeds are cleaned when the peels are softened, so that the peels are easy to rub.

In the step 2.1, a forest land with the altitude of 700-800 m and the canopy density of 0.2-0.5 is selected as a plantation, and compared with a naturally distributed forest land with the altitude of more than 1300m, the temperature is higher, so that the early germination of the terminal buds of the underground perennial roots is facilitated; and secondly, the canopy density is 0.2-0.5, and the canopy density is moderate, so that the seedlings can be planted in the planting furrows between adjacent tree crowns in a follow-up manner, weak illumination is formed, meanwhile, the water evaporation is slow, the formed microclimate can promote the longitudinal growth of the radix angelicae pubescentis plants, and the increase of fibers caused by high-temperature strong light is prevented. The canopy density is the degree of the canopy covering the ground in the forest, and is an index reflecting the stand density. According to the regulations of the food and agriculture organization of the United nations, the closed forest with more than 0.70 (containing 0.70) is compact forest, the closed forest with 0.20-0.69 is medium closed forest, and the forest with less than or equal to 0.1-0.20 (containing no 0.20) is sparse forest.

In step 2.2 of the invention, the seedling planting adopts seeds to cultivate big seedlings for more than 2 years, has no seedling revival stage, and is 2 years earlier than 1 year-old bare-rooted seedlings. Meanwhile, the nursery stock is cultivated automatically, so that the production cost can be reduced.

In step 5 of the method, wild radix angelicae pubescentis or artificially and conventionally planted radix angelicae pubescentis are collected in late middle and 4 months after the temperature rises. The invention can increase the ground temperature and promote the growth and development by covering the planting bed, and can carry out the 1 st batch of harvesting 20-29 days in advance. The cost is good, and the economic benefit of the grower is improved.

In step 6 of the invention, after the 1 st batch of pubescent angelica is harvested, the mulching film and the mulch are removed, so that the surface temperature can be reduced, the harvesting period of the 3 rd batch of pubescent angelica can be delayed, and the pubescent angelica can be prevented from developing adventitious roots in the mulch and influencing the recycling of the mulch.

In step 7.3 of the invention, when the length of the primary nutrient branches cultured in step 6 and the length of the secondary nutrient branches cultured in step 7.2 reach more than 55cm, the pinnate compound leaves are completely unfolded, and at the moment, the stems of the radix angelicae pubescentis are lignified, the fiber content is more, and the radix angelicae pubescentis is not easy to break. The branch pulling treatment is carried out in the middle and last ten days of 6 months, so that a large amount of adventitious buds at the root base can be promoted to germinate, the yield is improved, the harvesting period of 3 rd batch of pubescent angelica root is delayed, and the gap that the number of the pubescent angelica root is scarce after 7 months is filled. The branch pulling treatment method comprises the following steps: and (3) piling wood piles in 4 directions of the planting holes, straightening the primary nutrient branches and the secondary nutrient branches along 4 directions by using lines, wherein an included angle between every two adjacent wood piles is 90 degrees, and fixing the straightened primary nutrient branches and the secondary nutrient branches.

In step 9 of the invention, due to close planting and branch pulling, a large number of radix angelicae pubescentis adventitious roots and buds are covered on the planting bed in 3-4 years after the large seedlings are planted. The adventitious buds in unit area are too many, which causes the stems of the growing pubescent angelica root to be thin and weak, and the wild celery is needed to be transplanted at the moment. And carrying out intercropping by adopting a meristem propagation mode. Meristem propagation refers to separating the plant trophosome from the mother plant for planting separately and culturing into an independent new plant. Particularly, the method of weak moving, strong moving, dense moving and thin moving is used for interval moving, and the best method is to dig out the plant with long branch pulling time and grow adventitious roots. In order to ensure the later-period yield, 4-5 adventitious buds are reserved for each original plant. After the transplanting, the plant with the bud of which the upper half part is about 15cm long can be cultivated, a new plantation is cultivated, and the other parts can be processed into the traditional Chinese medicine 'Jiuyou pubescent angelica' for sale.

The invention has the beneficial effects that:

1. the invention adopts the seeds to cultivate the big seedlings for more than 2 years for field planting, has no seedling revival period, and leads the yield 2 years ahead of 1 year-old bare-rooted seedlings. Meanwhile, the nursery stock is cultivated automatically, so that the production cost can be reduced.

2. The invention can fix the nursery stock to the plantation with lower altitude, and cover the planting bed, to improve the ground temperature, promote the growth, and advance the harvest of 1 st batch by 20-29 days. The cost is good, and the economic benefit of the grower is improved.

3.
