Description

Technical Field

[0001] The invention belongs to the technical field of Ferula planting, and particularly relates to a film-covered drip irrigation water-saving planting method for Ferula macrocarpa. Background Art

[0002] Ferula, a perennial, one-time flowering, early spring short-lived plant of the genus Ferula in the family Apiaceae, is rich in beneficial ingredients such as ferulic acid. The oleoresin with a special onion-garlic smell secreted by the Ferula plant has been included in the herbal books of all dynasties and the Pharmacopoeia of the People's Republic of China. It has the effects of eliminating accumulation, dispersing lumps, and killing insects. It can be used to treat stomach problems, indigestion, abdominal pain caused by worm accumulation, and other diseases. It is the only source of traditional ethnic medicine and traditional Chinese medicine Ferula of ethnic minorities such as Uyghurs, Mongolians, and Tibetans in my country. Wild Ferula resources in Xinjiang are widely distributed. According to statistics, there are more than 20 kinds of Ferula resources, among which Xinjiang Ferula and Fukang Ferula are included in the Pharmacopoeia. However, due to excessive mining and the lack of reasonable protection of wild resources, Fukang Ferula has been listed as a Class II endangered plant.

[0003] In addition, the aboveground stems and leaves of Ferula foetida also have the effects of anti-inflammatory, anti-oxidation, and relieving gastric disease, and are a kind of health food with medicinal and edible properties. Among them, the aboveground part of Ferula foetida has high yield, long growth cycle, and its fragrance and taste are loved by local residents. Therefore, Ferula foetida can be used as a high-quality medicinal and edible product with the value of large-scale planting and promotion. However, the existing Ferula foetida planting is simulated field planting, which is generally planted on slopes and planted in small plots. It has the problems of much weed growth, large water consumption, inability to plant on a large scale, and low yield.

[0004] In view of this, the present invention proposes a new film-covered drip irrigation water-saving planting method for Ferula asafoetida, which can be used to carry out large-scale planting of Ferula asafoetida in suitable areas, and has the advantages of low cost and high yield. Summary of the invention

[0035] In order to further illustrate the film-covered drip irrigation water-saving planting method of Ferula australis of the present invention and achieve the intended purpose of the invention, the following is a detailed description of the film-covered drip irrigation water-saving planting method of Ferula australis proposed according to the present invention, its specific implementation method, structure, characteristics and efficacy are described in detail as follows in combination with the preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0036] The following will further introduce in detail the film-covered drip irrigation water-saving planting method of Ferula foetida of the present invention in conjunction with specific embodiments:

[0037] Ferula australis belongs to an early spring plant, and begins to germinate and emerge after the ice and snow melt, entering the growth period. Water shortage in spring causes soil compaction, which will affect the emergence rate. The film-covered drip irrigation water-saving planting method of Ferula australis described in the present invention adopts the planting method of drip irrigation under the film for the first time according to the growth habits of Ferula australis, covers the film to retain water and prevent soil compaction, and waters reasonably according to the spring rainfall to maintain soil moisture at 30-40%, thereby increasing the yield from 600-700 kg per mu (without film covering) to more than 1,000 kg.

[0038] The technical solution of the present invention is a technology for prolonging the growth time of Ferula foetida and reducing the growth of weeds and water consumption in Ferula foetida planting, which is:

[0039] A film-covered drip irrigation water-saving planting method for Ferula macrocarpa comprises the following steps:

[0040] Land selection: Choose a plot with an average temperature of 4-10℃ in February and March;

[0041] Sowing: Sowing in autumn, laying drip irrigation tape and covering film at the same time;

[0042] Post-sowing management includes: drip irrigation water management.

[0043] Preferably, the land is selected from a desert area at an altitude of 1000-1300 meters.

[0044] Preferably, the sowing is carried out at 5-10°C.

[0045] Preferably, the sowing is carried out in a hole sowing manner.

[0046] Further preferably, the hole sowing depth is 0.8-1 cm, with 3-5 seeds per hole.

[0047] In the above technical solution, due to the covering of the ground film, shallow sowing is not easy to cause seeds to fly away, which is more conducive to the germination of seeds above the soil.

[0048] Preferably, the sowing row spacing is 30-35 cm, and the plant spacing is 3-5 cm.

[0049] In the above technical solution, the film covering and shallow sowing can retain water and heat, thereby increasing the germination rate to at least 85%.

[0050] Preferably, the drip irrigation water management is: no watering is required after sowing, and water is provided 1-2 times before seedlings return, and 1-2 times during the growth period, depending on the spring precipitation of that year.

[0051] The "returning seedling" phenomenon refers to the phenomenon that the growth of crops is hindered due to certain reasons during their growth, which is manifested as yellowing leaves and stagnant growth. In the above technical solution, a stable soil moisture and temperature environment is created for Ferula by drip irrigation, so as to provide sufficient nutrients for the roots of Ferula dasyphylla, break the dormancy period of Ferula dasyphylla, avoid the yellowing of leaves and stagnant growth of Ferula dasyphylla during the dormancy period, extend the growth period of Ferula dasyphylla, and achieve the effect of planting for one year is equivalent to planting for many years in the wild; at the same time, it makes nutritional reserves for increasing production and income in the next year.

[0052] Preferably, the irrigation amount is 60-150 cubic meters per mu to ensure that the soil moisture content is 30-40%.

[0053] In the above technical solution, drip irrigation is used to ensure that the soil moisture content is 30-40%, which is more conducive to avoiding root rot or crop dormancy, prolonging the growth time of Ferula foetida, and reducing the growth of weeds and water consumption in Ferula foetida planting. Too high soil moisture content will cause root rot, thereby affecting the survival rate; too low soil moisture content will not easily break the dormancy of Ferula foetida.

[0054] Preferably, the drip irrigation water management uses a dripper flow rate of 0.75-2.0 L / h.

[0055] Preferably, the post-sowing management also includes grazing ban.

[0056] Example 1.

[0057] The specific steps are as follows:

[0058] (1) Land selection: The planting site of Ferula asafoetida should be located in a desert area with an altitude of 1000-1300 meters and an average temperature of 4-10℃ in February and March.

[0059] (2) Seed selection: Select seeds that are mature, plump, and undamaged.

[0060] (3) Sowing: Sowing in autumn, generally in September each year, depends on the weather conditions and the appropriate temperature (5-10℃) should be selected for sowing. At the same time, drip irrigation tape and film covering are laid. Specifically:

[0061] Use black mulch that meets the requirements of GB13735, drip irrigation and water-saving planting of asafoetida, asafoetida film-laying and seeder to assist in sowing and film-covering dripper. Before sowing: purchase drip irrigation tapes according to the specifications and quantity of drip irrigation tapes designed for the drip irrigation project. When sowing asafoetida, use the asafoetida film-laying and seeder to complete the work of laying tapes, covering films, covering soil, and pressing at one time. Use mulch that meets the requirements of GB13735, and encourage the use of high-strength, thickened, aging-resistant mulch that is easy to recycle and black mulch that can be completely degraded.
