Description
Technical Field
The invention belongs to the technical field of edible fungus cultivation, and particularly relates to a poria cocos planting method.
Background
Poria is a Chinese traditional medicinal material and food homologous food. The ancient people refer to the poria cocos as the immortal medicine for promoting the restoration of mind and the soul medicine for refining soul, and the modern medicine proves that the poria cocos has the effects of excreting dampness and promoting diuresis, tonifying spleen and invigorating stomach, calming the heart and soothing the nerves, detoxifying and resisting cancer and the like. According to statistics of third traditional Chinese medicine resource general survey data in China, in common traditional Chinese medicine clinical formulas, the compatibility rate of the poria cocos is over 70%, the number of Chinese patent medicines taking the poria cocos as a raw material is as much as 293, and health-care foods such as Qinggong famous point poria cocos cakes, poria cocos cakes and poria cocos wine taking the poria cocos as a raw material are deeply popular in the market. Because of its wide application range and large dosage, tuckahoe is known as one of the eight delicacies of the traditional Chinese medicines in common use. With the successful development of Chinese patent medicines and health-care products for poria cocos, especially after registration of the national autonomous intellectual property production of the 'Huangshen Ling' in the United states Food and Drug Administration (FDA), the first-choice Chinese patent medicine specially used for treating AIDS is collected by the United states pharmacopoeia (USD) in 2008 edition, and the demand of the poria cocos is getting larger and larger, so that the poria cocos becomes a popular precious Chinese medicinal material at home and abroad.
The Poria is derived from Poria cocos (Schw.) wolf of Polyporaceae, and the medicinal part is sclerotium thereof. The wild Poria cocos strain resource is widely distributed in east, middle and south provinces (regions) of China. Japan, southeast asia, oceania, and north america also have distributions. China is the country where tuckahoe is first discovered and applied in the world, and the medicine is recorded in Shen nong's herbal Jing, which has been in history for more than 2000 years. In ancient times of China, the poria cocos is used for a long time and supplied by wild resources mined by farmers in production areas, and the early production areas comprise: yanzhou, Changan, Shanxi Changan, Huayin, Henan Lingbao, Zhejiang Jiande, Yunnan Zhaotong and Hubei Macheng. The medicine is named as 'Yunnan Siberian cocklebur', and has high quality and large amount. With the continuous increase of medicinal use, wild resources can not meet the medical requirements gradually, thereby promoting the progress of converting wild poria cocos into artificial poria cocos.
However, since the 90 s of the last century, the main tuckahoe production areas in Fujian province have been mostly atrophied, gradually stagnated, and no longer planted on a large scale. The problems of high labor intensity, low labor efficiency and difficult guarantee of tuckahoe product quality exist in the traditional tuckahoe planting method which is adopted for many years.
The defects of the prior art are as follows: the wood chip strain poria cocos hyphae is not strong in adhesiveness and weak in hyphae; therefore, in the prior art, wood chip seeds are selected for strains, and the wood chips are rough and have multiple edges and corners, so that the wood chips are not easy to bag, the labor and the time are wasted during bagging, the labor intensity is high, and the efficiency is low. The invention adopts a formula mainly comprising corn, thus well solving the problems; and because the corn is rich in nutrition, the produced strain hyphae are strong and have stronger activity. In the existing cultivation technology, the tuckahoe strains are leaned against the ground and tightly attached to pine stumps and are easily disturbed by rainwater, so that the cultivation season is more selective in dry and rainy autumn. Because the temperature is low in winter, hyphae grow slowly, and the growth time is prolonged; when the poria cocos comes out, the poria cocos is high in water content and poor in quality in rainy spring. The method is not disturbed by rainwater, the tuckahoe can be planted in spring, the high temperature in summer is favorable for the growth of tuckahoe hyphae, and the tuckahoe growth time is shortened; the poria cocos is harvested in autumn and winter, so that rainy seasons are avoided, and the quality is good. In the prior art, the tuckahoe strains are inoculated by leaning against the ground of the stump, hypha grows from the base part of the stump to the inner part, the top part and the root part, and the tuckahoe begins to grow when the hypha grows to the root part and is close to the soil, but the hypha does not completely grow over the whole stump, so the obtained tuckahoe sclerotium is smaller, and the poria with hostwood is less. In the invention, because top inoculation is adopted, the poria cocos hyphae grow from the top of the stump to the root, when the hyphae grow to the root and are close to the soil, the whole stump is completely full of the poria cocos hyphae, and the obtained poria cocos sclerotia are large in number and high in yield; moreover, hyphae are fully grown on the fine roots, so the hyphae wrap the fine roots, and the poria with hostwood is easily formed. The poria with hostwood has stronger effect of calming heart and tranquilizing mind than the common poria with hostwood, and is more than 50 percent higher than the poria with hostwood for people with spleen deficiency and excessive dampness accompanied with restlessness of heart, insomnia and amnesia. The method achieves the effects of improved variety, improved method and increased income, and realizes cost saving, quality improvement and efficiency improvement of tuckahoe planting.
Disclosure of Invention
The invention aims to provide a poria cocos planting method, and solves the problems of low survival rate, high labor intensity, low yield, poor quality and the like of poria cocos planted in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
a tuckahoe planting method comprises the following steps:
(1) selection of mountain area and pine stump
The mountain land after pine cutting is selected, and the mountain land which is ventilated and exposed to the sun and has loose soil texture has better ideal effect of burning the mountain. The stump of the pine tree is better after being cut for 3 months to 10 months, and the stump diameter is better than 18 cm; observing whether the stump is rancid or not when the stump is cut for a long time, and checking the method: cutting a wood stump by a knife to obtain a wood block, and judging whether the wood degree is fresh or not and whether the original fresh yellow pine is carried or not; secondly, smelling the wood with nose to see whether the wood has the original fragrance of the pine; if the wood is blackened and water is discharged, the stumps which are damaged by worms and rotten and smelled rancid can not be used.
(2) Selection of strains
The corn particle seeds are selected as the strains, the corn particle seeds are rich in nutrition, hyphae are vigorous, the stress resistance is strong, the hyphae can be recovered quickly, and labor is saved during strain preparation. The culture medium formula for selecting corn particle seeds from the strains is as follows in percentage by mass: 55% of corn particles, 22% of pine sawdust, 20% of wheat bran, 1% of brown sugar, 1% of gypsum powder, 0.5% of magnesium sulfate and 0.5% of light calcium carbonate; according to the formula, the corn is soaked for 10-12h and fished up, the soaking time can be properly prolonged in the cold days, redundant water is drained, the required ingredients are fully and uniformly mixed, and the mixture is filled into a high-pressure propylene plastic bag with the thickness of 12-13 cm, 26 cm and 0.055 cm for high-pressure sterilization; when the pressure is increased to 0.05 kg, cold air is discharged, the pressure is returned to zero, then the pressure is continuously increased, when the pressure is increased to 0.15-0.2 kg, air is discharged and returned to the pressure position of 0.15 kg, and the air is discharged out of the pot after 3 hours, so that the sterilization is more thorough and no dead angle phenomenon exists; after the sterilization is finished, opening the pot cover when the pressure reaches 0 kg, taking out the pot, cooling the materials in a clean and sterile cooling chamber to a temperature below 28 ℃ and inoculating; inoculating, culturing at 23-26 deg.C in clean and ventilated culture room, culturing for 15 days, and collecting mycelium over the bag for 20 days.
The strain selection can be realized by 'seeing, feeling and smelling the strains at once', and the strains with high quality and high yield can be selected only by combining the seeing, feeling and smelling the strains. See: whether the hypha of the strain is vigorous or not and no pollution exists. Touch: the fungus bag has elasticity, consistent tightness and firmness. Smelling: breaking the strain into half and half, smelling pine fragrance and Poria odor, and if there is peculiar smell, it cannot be used.
(3) Site arrangement
Splitting weeds at the edges and the periphery of the stump of the selected mountain field, planing ground soil of 30 cm around the stump of the pine tree by using a hoe, cutting off rough bark, and exposing and drying the stump of the pine tree.
(4) Planting
Inoculating the top of the stump of the pine: under the premise of digging soil, exposing roots, and drying in the sun. Sawing a new opening of the original cut stump of the pine about 5 cm downwards by using a chain saw, reserving a quarter of the new opening to be not sawed off, and splitting the stump of the pine by using an axe (paying attention to the fact that the reserved part is above a backer); selecting the using amount according to the size of the stump, wherein the using amount of the stump of 20 centimeters is generally 2-3 bags, and the larger the stump is, the larger the using amount is; a small strip with the width of 1 cm is cut on the surface of a relatively flat strain bag by a small knife, and the length of the small strip is as long as that of the strain bag (the cut plastic needs to be removed); the cut strips are placed downwards at the sawn new opening, and the strains are fixed by plastic adhesive tapes so as not to move. Covering the upper part of the stump with a plastic film, a garbage bag, a food bag and the like to avoid rain (two ventilation openings are reserved below the covered plastic to facilitate ventilation and oxygenation, covering objects such as leaves or grass and the like are found to cover the plastic film, the covering objects grow more than 10 cm longer than the stump, and the covering objects are pressed by sawn wood blocks, stones, mud blocks, branches and the like to prevent the sawn wood blocks from being blown away by wind, and the sawn wood chips are cleaned to prevent white ants from growing.
(5) Managing
The tuckahoe strain is planted and then is subjected to on-duty inspection and on-duty management, wherein the conditions of hypha spawning, mixed fungus pollution and the existence of white ant harm are mainly inspected, the hypha is recovered 2 days after the tuckahoe strain is planted generally, the hypha is white villous and extends to a stump of a tree after 7 days, and a large number of small water drops are contained in a plastic film, so that the successful inoculation and good growth of the tuckahoe strain are shown; if the bacterial strain is polluted by infectious microbes or harmed by white ants, the polluted bacteria are taken out in time and then sawed for reseeding. Generally, the patrol is carried out once in half a month, and the problem is found and solved in time. Although Poria should be exposed to the sun and not dry, it is impossible to direct the sun directly to the fruit body to prevent it from cracking and rotting. When the tuckahoe is exposed out of the ground, soil is covered on the ground or the tuckahoe is covered by leaves, weeds and the like to prevent the exposed tuckahoe from being broken by direct sunlight and rotting the tuckahoe after raining.
The invention has the advantages that:
1. adjusting the planting season, shortening the growth time and avoiding harvesting in rainy season. Poria is dry and not wet when growing; due to more rainwater in spring in south, the growth of the hypha of the poria cocos is not facilitated, so that dead seeds are caused, and the inoculation survival rate is less than 50%. In the prior art, tuckahoe is planted at the end of summer and in autumn and harvested in spring of the next year. Because the poria cocos is high-temperature fungoid, hyphae grow slowly at the temperature of lower than 20 ℃, and basically stay in a dormant state at the temperature of lower than 15 ℃, the poria cocos is generally in the dormant state from 12 months to 2 months of the next year, the poria cocos can be produced quickly when the temperature rises to above 20 ℃, and if the poria cocos planted after 7 months can be harvested in 5 months of the next year, the growth time is prolonged invisibly; the harvesting season just happens to be in rainy season, the harvested poria cocos is poor in quality, and phenomena such as poria cocos rotting are easy to occur, so that the yield and the quality are affected. Because the temperature is low in winter, hyphae grow slowly, and the growth time is prolonged; when the poria cocos grows out, the poria cocos is high in water content and poor in quality in rainy spring. The poria cocos is planted in spring and collected in autumn and winter, and the problems are well solved.
2. The selected corn strains are strong and strong, have strong stress resistance, and are labor-saving and time-saving in bagging. The wood chip strain poria cocos hyphae is not strong in adhesiveness and weak in hyphae; therefore, in the prior art, wood chip seeds are selected for strains, and the wood chips are rough and have multiple edges and corners, so that the wood chips are not easy to bag, the labor and the time are wasted during bagging, the labor intensity is high, and the efficiency is low. The invention adopts a formula mainly comprising corn, thereby well solving the problems; and because the corn is rich in nutrition, the produced strain hyphae are strong and have stronger activity.
3. The inoculation position and the planting mode are changed, the yield is high, the poria with hostwood is more, and the benefit is good. In the prior art, tuckahoe strains are leaned against the ground and tightly attached to pine stumps, so that the tuckahoe strains are easily invaded by rainwater to cause the death of the strains; hypha grows from the outer part of the stump to the inner part, the top part and the root part, when the hypha grows to the root part and is close to the soil, the tuckahoe begins to grow, and the hypha does not completely grow over the whole stump, so the obtained tuckahoe has smaller sclerotia and less poria with hostwood. Because the top inoculation is adopted, the poria cocos hyphae grow from the top of the stump to the root, when the hyphae grow to the root and are close to the soil, the whole stump is completely full of the poria cocos hyphae, and the obtained poria cocos sclerotia are large in number and high in yield; moreover, hypha is fully grown on the thin roots, and the hypha wraps the thin roots, so that the poria with hostwood is easily formed, and the effect of calming the heart and soothing the nerves of the poria with hostwood is stronger than that of the common poria with the ordinary poria. The purchase price is more than 50 percent higher than that of the tuckahoe.
4.
