Description
Technical Field
The invention relates to the field of aquatic traditional Chinese medicinal material cultivation, and in particular relates to a three-dimensional planting and cultivating method of rhizoma alismatis, whitmania pigra and hyriopsis cumingii.
Background
The whitmania pigra belongs to the genus whitmania of the class of the phylum Anomalia, which is called leech, whitmania pigra and whitmania pigra, is widely distributed in ditches, paddy fields and lakes in China, is a leech type of traditional Chinese medicine with higher use value, mainly embodies the medicinal performance in containing anticoagulant polypeptide (named leech polypeptide), oligopeptide, strong plasmin and other anticoagulant substances and heat-resistant polypeptide components, and has excellent curative effects on treating cardiovascular and cerebrovascular diseases, hyperlipidemia and the like clinically. At present, most of the leeches of whitmania pigra come from wild fries, the number of wild groups is sharply reduced due to environmental pollution and excessive fishing, and the contradiction between market supply and demand is prominent. The artificial culture of the whitmania pigra whitman becomes a necessary way for realizing the intensification and high-quality development of the industry, the culture period of the whitmania pigra whitman is short, the whitmania pigra whitman has the characteristics of quick growth, strong disease resistance and the like, the whole culture process can be completed from a seedling stage of 5 months to 10 months every year by using commercial leeches, and the main feeds are ampullaria gigas, oncomelania gigas and various plankton organisms, and the waters which are strong in concealment and are rich in fertilizer are favored. At present, the artificial culture of whitmania pigra is in a development stage, the technical aspects of culture mode, artificial breeding, bait research, disease control and the like are not mature, the culture mode mainly comprises a pond and a net cage, and the higher income with the net profit of 10000 yuan can be realized for the single culture of the whitmania pigra per mu of water area. However, under intensive culture conditions, temperature, dissolved oxygen, water quality and the like become key factors influencing the survival rate of the whitmania pigra. The water body can die when the temperature is too high or too low, and particularly, a great deal of death is easily caused by high temperature due to direct sunlight in summer; on the other hand, residues generated after the whitmania pigra inhales snails are extremely easy to decay, and a large number of plankton and germs are bred, so that the environment of the culture water body is polluted. Therefore, the artificial culture of the whitmania pigra has the problems of low survival rate, low yield, high investment cost and the like which need to be solved.
The alisma orientale is a perennial swamp herb plant of alisma in alismatis family, also named swan egg, water, prefers to fertilizer water, grows in shallow water zones of lakes, estuaries, creeks and ponds, and also grows in swamps, ditches and low-lying wetlands, is a traditional Chinese medicine commonly used in the clinical practice of traditional Chinese medicine, has the effects of promoting diuresis, excreting dampness, resolving turbidity, reducing blood fat and the like, has the effective functions in the aspects of diuresis, resisting non-alcoholic fatty liver, resisting liver injury, resisting cholestasis, reducing blood fat, resisting inflammation, resisting tumors and the like due to the tuber containing the protopanaxarene type tetracyclic triterpenes, and is an important raw material of famous Chinese patent medicines such as six-ingredient rehmannia pills, gentian liver-purging pills and the like. The seeding period of the rhizoma alismatis is generally 2-3 months, the rhizoma alismatis can be harvested within 9-10 months, tubers of the rhizoma alismatis can be collected to be processed and used as a medicine, and the rhizoma alismatis planting method has the advantages of short growth cycle and low planting risk. At present, most of the plants are planted in rice fields, such as Sichuan, Chongqing, Fujian, Guangxi and the like, rice-alisma orientale crop rotation is adopted, and the mode accounts for more than 90 percent of the whole country; the rotation of 'lotus-rhizoma alismatis' is adopted in Jiangxi and other places, and the planting area of the mode in China is less than 5 percent.
The hyriopsis cumingii is a hyriopsis cumingii belonging to the family of pearly mussel of the class of lamellibranchia, also called a hyriopsis cumingii, a water shell, a pearl mussel and the like, is a special excellent bivalve shellfish for culturing pearls in fresh water in China, is a basic source of precious medicinal material pearls, and accounts for more than 80% of the yield of fresh water pearls in China. The pearl produced can be used as a decoration, has the functions of purging heat and arresting convulsion, preventing corrosion and promoting granulation, improving eyesight and detoxifying, relieving cough and reducing sputum, tendering skin and whitening skin and the like, and is the main component of more than 20 Chinese patent medicines. The hyriopsis cumingii inhabits at the muddy bottom or shallow water layer of a shoal, lives in camps and buries, depends on the activity of axe feet, cannot actively forage, and swings through the branchia cilia of cilia on the inner side of the mantle membrane to cause water flow to filter food such as monadaceae, protozoa and organic debris, so that the water body purification effect is very obvious. At present, hyriopsis cumingii is mostly mixed with freshwater fishes such as grass carp, crucian carp, silver carp, bighead carp and the like in a pond, but the problems of inconsistent specifications, low survival rate and the like caused by uneven density of the hyriopsis cumingii due to free crawling at the bottom of the pond still exist.

First, the water quality in the ponds of example 1 and comparative example 2 at the time of harvest was measured, and the results of the water quality measurement are shown in table 1 below:
TABLE 1
As can be seen from Table 1, the three-dimensional breeding method of Alisma orientale, whitmania pigra and hyriopsis cumingii can effectively improve the water quality.
Furthermore, the yield and survival rate of Whitmania pigra Whitman of example 1 and comparative example 2 at harvest were determined as shown in Table 2 below:
TABLE 2
| Yield per mu unit (kg) | Survival rate (%) | Monovalent (Yuan/kg) | Benefits (yuan) | |
| Comparative example 2 | 300.09±15.64 | 41.35±3.51 | 180～200 | 8000～10000 |
| Example 1 | 375.78±10.12 | 61.27±2.78 | 180～200 | 16000～20000 |
As can be seen from Table 2, compared with the existing single culture mode of whitmania pigra, the three-dimensional breeding method of alisma orientale, whitmania pigra and hyriopsis cumingii can improve the survival rate of whitmania pigra from 41.35% to 61.27%, and can improve the yield of whitmania pigra from 300.09 kg/mu to 375.78 kg/mu;
next, the yields of alisma orientale from example 1 and comparative example 3 at harvest were determined, and the results are shown in table 3 below:
TABLE 3
| Yield per mu unit (kg) | Monovalent (Yuan/kg) | Benefits (yuan) | |
| Comparative example 3 | 250.52±25.67 | 30 | 4500 |
| Example 1 | 150.34±5.25 | 30 | 2500 |
As can be seen from Table 3, although the yield of Alisma orientale in the Alisma orientale-Whitmania pigra Whitman-hyriopsis cumingii three-dimensional cultivation method is only 150.34kg compared with the existing Alisma orientale single planting cultivation mode, the Alisma orientale obtained by the method is only an additional product for cultivating Whitmania pigra Whitman, belongs to an additional harvest,
finally, the pearl yields of example 1 and comparative example 4 at harvest were determined, and the results are shown in table 4 below:
TABLE 4
