Description

TECHNICAL FIELD

[0001] The application relates to the field of medicinal material planting, in particular to a field planting method of low-altitude Dui Yimei. BACKGROUND

[0002] Dui Yimei grass only grows in high-altitude areas, and in addition, wild Dui Yimei has a growth cycle of 3-5 years, is slow in growth, has a long growth cycle, and can be harvested for medicinal use only after many years, has a low germination rate, a small quantity, and a very low harvest quantity, and thus leads to a low market supply. SUMMARY

[0003] In order to promote the germination rate of Dui Yimei seeds and shorten the growth cycle, the application provides a field planting method of low-altitude Dui Yimei.

[0004] The field planting method of low-altitude Dui Yimei provided by the application adopts the following technical scheme:

[0005] A field planting method of low-altitude Dui Yimei, comprising the following steps:

[0006] Step 1: seed selection, in the autumn harvest season, completely mature Dui Yimei seeds are collected in an alpine meadow area with an altitude of 3600-5100 m, impurities are removed, full-grain seeds are screened, and the seeds are dried until the water content is below 10%; during the drying period, the seeds are frequently stirred and checked, and if there is mildew, the seeds are picked out;

[0007] Step 2: site selection, a rain-fed type wasteland or cultivated land with an altitude of 2300-3200 m is selected as a planting area, the annual rainfall is more than 500 mm, the average annual temperature is about 5 DEG C, the light radiation is strong, and the number of rainy days is more than 120 days / year; the planting area is divided into multiple plots by digging soil ridges, each plot has an area of 200-300 m 2 , and drainage is reserved;

[0008] Step 3: soil treatment, in early April, the soil is thawed, the soil pH is measured, if the soil is alkaline, a proper amount of sulfur powder and lime are spread, and organic fertilizer is applied; along the north-south direction, deep plowing and fine harrowing are performed, and the plowing depth is 30-50 cm;

[0009] Step 4: seed treatment, in late April, the seeds are treated to break dormancy, the seeds are first soaked in fruit peel water for 1-2 h; then the seeds are treated by seed dressing with light carbon nuclear fertilizer, the light carbon nuclear fertilizer is diluted with water to a concentration of 5-10%, and the light carbon nuclear fertilizer is sprayed on the seeds for seed dressing treatment, and the seeds are dried or air-dried;

[0010] Step 5: sowing, the seeds obtained by the treatment of step 4 are mixed with sand and soil, and then sowing is carried out, the sowing amount is 5 kg per mu, the sowing depth is 1.5-3 cm, the row spacing is 20-25 cm, and the plant spacing is 10-15 cm; after sowing, sufficient tamping is carried out, and a mulch film is laid, the width of the mulch film is 0.8 m, after laying the mulch film, the edges of the mulch film are compacted, the integrity of the mulch film is checked, if there are broken parts, they are sealed in time, and the mulch film is broken in time when the seedlings emerge;

[0011] Step 6: field management, weeds are removed in early June, and field disease and pest management is carried out, a shading net is built, and field drainage is strengthened during the rainy season; basal fertilizer is applied once in late June, and the light carbon nuclear fertilizer is applied in the ditch between the rows, and the application amount is 15 kg per mu.

[0012] By adopting the above technical scheme, since the moisture content of generally newly harvested seeds is as high as 25-45%, the seeds with high moisture content have high respiration intensity, release a large amount of heat and moisture, are prone to heat and mold, or quickly consume the oxygen in the seed pile and die due to anaerobic respiration, or die due to freezing damage in subzero low temperature. Therefore, in order to prevent the seeds from being moldy and frozen due to over-limit moisture content, maintain the vigorous germination and vitality of the seeds, improve the quality of the seeds, prevent the seeds from losing vitality, and enable the seeds to safely pass through the storage period from harvesting to sowing, the moisture content of the seeds is controlled to be below 15%.

[0013] Since Duiyi is suitable for growing in neutral or acidic environment, after identifying the pH value of the soil, the alkaline soil can be changed into slightly acidic or neutral soil by using appropriate amount of sulfur powder and lime, without destroying the nutrient components of the soil, and the sulfur powder and lime have sterilization effect, which can effectively kill various diseases and pests in the soil.

[0014] When the seeds are broken from dormancy, the seeds are soaked in fruit peel water first, since the fruit peel water is generally acidic, appropriate concentration of the fruit peel water not only enables the Duiyi seeds to break from dormancy as soon as possible, but also supplements the nutrients for the seeds, and is safe, harmless and environmentally friendly. In addition, the fruit peel water can also adjust the acidity of the soil, the seeds soaked in the fruit peel water can adjust the acidity of the surrounding soil according to the acidity carried by the seeds, so that the acidity of the surrounding soil is adapted to the acidity required by the seeds. Then, the light carbon nuclear fertilizer is sprayed on the surface of the seeds soaked in the fruit peel water, after the seeds are sowed, the light carbon nuclear fertilizer provides carbon and other nutrients for the germination of the seeds, promotes the germination of the seeds, speeds up the germination speed of the seeds, improves the survival rate of the seeds, and balances the nutrient absorption in the later period. After the seeds develop into seedlings in the later period, the light carbon nuclear fertilizer is applied again, which can promote root growth, seedling growth, flowering, fruit setting, promote fruit differentiation, and also promote the leaves of Duiyi to capture carbon dioxide in the air, manufacture chlorophyll under sunlight, accumulate carbon, hydrogen and oxygen which are essential for the growth of seedlings, absorb, synthesize and transform nitrogen, phosphorus and potassium and other organic components in the soil, and promote the gestation and growth of Duiyi seedlings.

[0015] After sowing, it is necessary to carry out full compaction, lay plastic film, which can play a role in heat preservation, prevent freezing, and also can keep moisture, reduce evaporation, ensure the humidity of the growth environment of Duiyi, and can also avoid contact with pests.

[0016] In summary, not only promotes the germination of Duiyi seeds, increases the survival rate of seeds, but also effectively shortens the growth cycle of Duiyi, speeds up the growth of Duiyi, and improves the market supply of Duiyi.

[0017] Preferably, the planting area selected in step 2 is a planting area with flat terrain, loose soil, good drainage, no irrigation conditions, and mainly mature soil or sandy loam.

[0018] By adopting the above technical scheme, since the growth environment of wild Duiyi has certain requirements, the wild growth environment of Duiyi is imitated, and all favorable environments for the growth of Duiyi are provided, which not only makes the growth of Duiyi more vigorous and rapid, but also does not destroy the original quality and taste of Duiyi.

[0019] Preferably, the organic fertilizer includes 15-25% sheep manure, 15-20% cow manure, 3-10% rabbit manure, 10-15% straw powder, and the rest is wood ash.

[0020] By adopting the above technical scheme, since the Qinghai-Tibet Plateau is mainly based on animal husbandry, cow manure and sheep manure are common organic fertilizers, and the use of cow and sheep manure not only does not destroy the soil environment, but also can make full use of the sufficient fertilizer nearby. And Duiyi is a food that plateau pika likes to eat, so there are usually a lot of rabbit manure near wild Duiyi, and the more rabbit manure, cow manure and sheep manure, the more Duiyi. Therefore, adding an appropriate amount of rabbit manure to the commonly used cow and sheep manure will make Duiyi absorb more original nutrients, so as to ensure the quality of artificially planted Duiyi.

[0021] Preferably, the fruit peel water is obtained by soaking and fermenting pomelo peel and banana peel with a mass ratio of 5:2 for 3-5 weeks, and diluting the obtained solution.

[0022] By adopting the above technical scheme, since the banana peel contains a large amount of peels and a variety of trace elements and vitamins, it helps to supplement nutrients for seeds, and also helps to inhibit the reproduction and growth of fungi and bacteria, and the ethylene contained in the banana peel can promote seed germination. And the pomelo peel also contains a lot of nutrients, such as a variety of trace elements, including iron, calcium, zinc, magnesium and potassium, etc. These trace elements are the nutrients needed for the growth of Duiyi. In addition to eliminating odor and inhibiting pests, it can also provide rich nutrients for seeds, so that Duiyi grows more vigorously in the later stage, and the branches and leaves are more green and healthy.

[0023] Preferably, the light carbon nuclear fertilizer in steps 4 and 6 comprises 10-15 parts by weight of microalgae, 5-10 parts of sodium carbonate, 3-7 parts of sodium bicarbonate, 4-8 parts of coke and 20-30 parts of yeast sugar.

[0024] By adopting the technical scheme, since the microalgae contains chlorophyll a and can perform photosynthesis, the photosynthesis of the seed can be assisted in the early stage of germination. The sodium carbonate and sodium bicarbonate can produce carbon dioxide in the soil in contact with air, and the coke can absorb the carbon dioxide gas released by the sodium carbonate and sodium bicarbonate as an adsorbent, thereby continuously providing carbon for the seedling of the Duiyi, and the seedling can transport the carbon to the stem and leaf parts. Through the absorption of carbon dioxide, the promotion of photosynthesis, the inhibition of light respiration and the prevention of pests and diseases, the amount of carbon dioxide fixed by the Duiyi is promoted, thereby providing the seed and the seedling with absorbable and usable nutrient elements to promote the growth of the seedling.

[0025] Preferably, the seed treated by the light carbon nuclear fertilizer is sowed in time within 1-7 days after being dried in the sun or air-dried.

[0026] By adopting the technical scheme, since the treated seed has a time limit, the seed is sowed in time after being dried in the sun or air-dried, so that the germination rate and survival rate of the seed can be effectively improved.

[0027] Preferably, the weight ratio of the seed to the sand in step 5 is 1:2.

[0028] By adopting the technical scheme, since the soil is relatively sticky, the drainage property can be effectively improved by mixing the sand, the germination rate can be improved, the growth of the seedling can be promoted, the growth of the root system can be promoted, and the seedlings are healthy and neat.

[0029] Preferably, the pest and disease management method in step 6 is to prepare a lime nitrogen aqueous solution with a concentration of 20-30%, spray the lime nitrogen aqueous solution in the planting area, and then spray the fruit peel water again after 1-2 days.

[0030] By adopting the technical scheme, since the lime nitrogen is a mixture composed of calcium cyanamide, calcium oxide and other insoluble impurities, can be quickly dissolved in water, mainly releases monocyandiamide and dicyandiamide through decomposition, and can effectively kill underground pests such as grubs, wireworms and mole crickets by spraying the lime nitrogen aqueous solution in the season when the pests are more, and can effectively inhibit the pests on the ground by spraying the fruit peel water, and can also be used as an alkaline fertilizer to alleviate the soil alkalization. Therefore, the quality and yield of the Duiyi are improved, and no residual poison is left in the soil, and the operation is safe.

[0031] In summary, the application has the following beneficial effects:

[0032] 1. Because the present application adopts appropriate amount of sulfur powder and lime, alkaline soil can be changed into slightly acidic or neutral soil, soil nutrients will not be destroyed, and sulfur powder and lime have the effect of sterilization, which can effectively kill various pests and diseases in the soil. When breaking dormancy of seeds, first soak the seeds in peel water, not only can seeds be broken dormancy as soon as possible, but also can also supplement nutrients for seeds. In addition, peel water can also regulate the acidity of the soil, so that the acidity of the surrounding soil is adapted to the acidity required for seeds. Then, light carbon core fertilizer is sprayed on the seed surface soaked in peel water. After seeds are sown, light carbon core fertilizer provides nutrients such as carbon for the germination of seeds, promotes seed germination, and accelerates seed germination speed, improves the survival rate of seeds, and balances nutrient absorption in the later stage. In summary, not only the germination of Radix Angelicae Pubescentis seeds is promoted, the survival rate of seeds is increased, but also the growth cycle of Radix Angelicae Pubescentis is effectively shortened, the growth rate of Radix Angelicae Pubescentis is accelerated, and the market supply of Radix Angelicae Pubescentis is improved.

[0033] 2. Banana peel and grapefruit peel are preferably used in this application because they contain a large amount of trace elements, which can help to supplement nutrients for seeds and inhibit the reproduction and growth of fungi and bacteria in seeds. In addition, the ethylene contained in banana peel can promote seed germination and make the later growth of Lamiaceae more vigorous, and the branches and leaves more green and strong.

[0034] 3. According to the method of the present application, sodium carbonate and sodium bicarbonate can produce carbon dioxide when in contact with air in the soil, and coke can act as an adsorbent to absorb the carbon dioxide gas released by sodium carbonate and sodium bicarbonate, thereby continuously providing carbon for the Lamiaceae seedlings. The seedlings then transport the carbon to the stems and leaves. The stems and leaves absorb carbon dioxide, promote photosynthesis, inhibit photorespiration, and prevent and control diseases and pests, thereby promoting the fixation of carbon dioxide by the Lamiaceae, thereby providing absorbable and utilizeable nutrients for the growth and development of seeds and seedlings, enabling the seedlings to grow healthily.

[0082] Comparative Example

[0083] Comparative Example 1

[0084] The difference from Example 2 is that in step 4: seed treatment, in late April, the seeds are treated to break dormancy, the seeds are soaked in the fruit peel water for 1-2 h, and then directly dried in the sun or air-dried; no light carbon nuclear fertilizer is sprayed before sowing.

[0085] Comparative Example 2

[0086] The difference from Example 2 is that in step 4: seed treatment, in late April, the seeds of Duiyiwei are not soaked in the fruit peel water, but are directly sprayed with the 7.5% light carbon nuclear fertilizer diluted with water, and then sown after drying in the sun or air-drying.

[0087] Comparative Example 3

[0088] The difference from Example 2 is that no plastic film is laid after sowing.

[0089] Comparative Example 4

[0090] The difference from Example 2 is that in Step 6: field management, weeds are removed in early June, a shading net is set up, and field drainage is strengthened during the rainy season; in late June, a light carbon core fertilizer is applied once by trenching in the row, and the application amount is 15 kg per mu, and no 25% lime nitrogen aqueous solution is sprayed.

[0091] Performance detection test

[0092] Test method

[0093] According to the method in the above examples and comparative examples, Duiyi is planted and cultivated, and the germination rate of the seeds after one month after sowing and the growth period of Duiyi from sowing to harvest are observed and recorded. The judgment of the harvest period is based on the flowering or bud setting of Duiyi plants (seed germination rate = (germinated seed number / seed number for test) x 100%). Each test is done in triplicate, and the average value is taken.

[0094] Table 1

[0095] Implementation project Seed germination rate / % Growth cycle Example 1 86.2 Three years Example 2 89.1 Three years Example 3 90.2 Three years Comparative Example 1 75.3 Four years Comparative Example 2 79.1 Four years Comparative Example 3 41.5 Five years Comparative Example 4 79.8 Four years

[0096] In combination with the examples and comparative examples and in combination with Table 1, it can be seen that when the seeds are treated to break dormancy, they are not soaked in peel water or sprayed with light carbon core fertilizer, the germination rate of the seeds will decrease, and the growth period will be extended, indicating that the growth of Duiyi is closely related to the early treatment of the seeds.

[0097] In combination with Example 2 and Comparative Example 4 and in combination with Table 1, it can be seen that when no 25% lime nitrogen aqueous solution is sprayed in the later field management, it will also affect the growth period of Duiyi, which may be due to the rampant pests in the field causing Duiyi to lack nutrients.

[0098] In combination with Example 2 and Comparative Example 3 and in combination with Table 1, it can be seen that in the plateau region, if no plastic film is laid after sowing, it will seriously affect the germination and growth of Duiyi seeds, which is closely related to the climate of the plateau and the growth conditions of Duiyi.

[0099] The specific embodiments are merely an explanation of the present application, and are not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the present specification, and as long as the modifications are within the scope of the claims of the present application, they are protected by the patent law.
