The technique of planting Poria cocos in situ with Pine Tree Fruit

Masson pine, black pine, easy to infect pine nematode disease, many forest farms after felling, rational use of pine trees remaining in the mountain planting medicinal fungus Poria cocos, turn waste into treasure. The key techniques of cultivating Poria cocos are introduced as follows:

Poria cocos are parasitic on the roots of Pinus massoniana or black pine, showing oblate and irregular spheres. Under normal circumstances, pine trees with a diameter of 15-20 cm produce 17-20 kg of fresh Poria cocos in 6 months.

The quality of strains is an important factor related to the success or failure of cultivation and high or low yield. inferior strains only grow hyphae and do not bear cocos. Due to the infinite propagation of the strain, the sclerotia performance gradually declined, and the original high yield performance was lost. The high-quality strain has the advantages of stable inheritance, strong stress resistance, wide adaptability, exuberant mycelium growth and white and sturdy concentration. After more than 10 years of screening, we have selected the high-yielding strain "Fengchong No. 1". It is suitable for continuous root cultivation of pine trees and Linden wood cultivation, with Ling concentrated in the range of 1 meter, drought resistance and high yield. Under the cultivation of Linden and Linden, the yield is as high as 40 kg, and the maximum weight of single Ling is 30 kg.

1. Select the field and choose the winner. Select the land with a slope of 10-30 degrees, sunny leeward, loose soil and good drainage and air permeability. If the permeability of clay, black soil and loess is poor, Poria cocos can also be planted, but the yield is slightly different. You can choose the pine trees cut down in the autumn, winter or spring of the first year, with a diameter of more than 12 centimeters, no decay, insect column, and Poria cocos can be cultivated if the bark has not fallen off.

2. Digging holes to clear the body. The quality of digging holes is directly related to the yield of Poria cocos. In order to grow Poria cocos well, it is necessary to dry the material in the dry field and have good strain quality. The Qing Dynasty is generally around the Spring Festival to the Qingming Festival, and it should be finished by the end of May at the latest. Weeds, shrubs and stones should be removed within 1 meter, holes with a diameter of 1 meter and a depth of 40 centimeters should be dug, and the soil of the lateral roots should be hollowed out to fully expose the space. The soil dug out should be weathered and dried at the edge of the hole, and be backfilled after inoculation.

3. Inoculate and cover the soil. The best inoculation season is from April to July. No later than August at the latest. Early inoculation, low temperature, slow bacteria, easy pollution, affect the success rate; too late inoculation, affect the yield. It is appropriate to choose sunny weather, choose thick pine roots to cut the "human" shape gap with a knife, do not cut off small roots, fill the cut with bacteria, prevent bacteria from breaking away from the tree, cover the papyrus, sprinkle the edge of the papyrus with termite powder, cover the soil in time, and bury the firewood dug out when hollowing out into the hole at the same time. When covering the soil, pick up sundries and stones, and cultivate the tree stalks into the shape of the tortoise back.

The amount of inoculation should be appropriate, and the amount of inoculation is too much, which will affect the yield. If the inoculation amount is too small, the mycelium is difficult to spread rapidly, and the yield is also affected. It is generally 20 cm in diameter, 350 grams in 1 bag, 2 bags in 25-35 cm in diameter, 3 bags in 35-45 cm in diameter, and inoculated in 3-5 points.

4. Post-vaccination management. Ten days after inoculation, gently peel off the topsoil to reveal the bacteria. If the mycelium is white and begins to spread to the pine root, it means that the strain survives and the soil should be covered. If the strain dies or pollutes the miscellaneous bacteria, it can be re-cut and inoculated. If the mycelium is thin and weak, it is due to the high soil moisture on the covered pine, the strain can be shaded, the covering soil can be removed to bask in the sun for 2-3 days, and then covered with soil to promote the healthy growth of the mycelium.

About 50 days after inoculation, the hyphae spread to the whole tree and the hyphae kink to form sclerotia. The sclerotia will be exposed to the ground mound for a certain period of time, so it is necessary to cultivate the soil several times in time, and the thickness of the sclerotia should not be exposed. Pine trees should open good drains and drain them in time after the rain. Pine nut exposed, should be timely soil cultivation, Poria field to prevent livestock trampling.

5. Harvest. After about 10 months of growth, Poria cocos can be harvested one after another when the sclerotia of Poria cocos hardens and the surface is yellowish brown. Prevent the breaking of Poria cocos during harvest so as not to affect the grade of finished products. It is not suitable to dig large pine trees on rainy days. Cover the soil again after excavation, and it can be harvested for 2-3 years.
