Description

Technical Field

[0001] The invention relates to the technical field of morel cultivation, in particular to a method for cultivating morels without grain. Background Art

[0002] Morchella is a rare edible mushroom variety, named for its uneven cap surface, which looks like a sheep's tripe. Morchella is also called sheep's tripe vegetable, sheep mushroom, and sheep's tripe mushroom. It is a precious edible and medicinal mushroom with a unique taste and fresh fragrance, and high nutritional and health value. Therefore, with the substantial improvement of people's living standards, people's demand for morels is increasing, and the cultivation of morels is also increasing. Because the traditional wild-simulating cultivation method has problems such as long growth cycle, high cost, and low yield, it cannot meet people's living needs. Therefore, artificial cultivation of morels is mainly carried out under greenhouse conditions, especially in the north. Due to the low temperature in winter, it must be cultivated in a greenhouse to ensure the fruiting time.

[0003] At present, the cultivation method of morels in greenhouses mainly uses wheat as the bacterial strain base material and nutrient bags for cultivation. The existing planting steps include preparing bacterial strains and nutrient bags, land preparation, sowing, covering soil, watering, waiting for a week, placing nutrient bags, and covering ground film. Generally, it takes more than a week to complete the planting process. However, there are some problems with the existing cultivation method: on the one hand, if wheat is used as the bacterial strain base material and nutrient bags, more than 1,500 catties of wheat are required per mu of land, and the price of making bacterial strain base materials and nutrient bags per mu of land is as high as more than 6,000 yuan. The cost is high while consuming more staple food, which reduces the economic benefits of the enterprise; on the other hand, the existing planting steps are relatively complicated, and the time required for cultivation is relatively long. Since the nutrient bags are placed late, the placement of the nutrient bags cannot be 100% determined to match the sowing position. After the mycelium grows in the soil, it cannot be guaranteed to grow into the soil and the nutrient bags at the same time. The utilization rate of the nutrient bags is low, and the cultivation efficiency of morels is low. Summary of the invention

[0004] In order to solve the technical problems in the prior art that the existing cultivation method consumes more staple food and has high cost, reduces the economic benefits of the enterprise, takes a long cultivation time, has low utilization rate of nutrient bags, and has low cultivation efficiency of morels, the present invention provides the following technical solution.

[0005] The present invention discloses a method for cultivating Morchella edulis without grain, comprising the following steps:

[0006] S1: Prepare fungus and nutrient bags according to the scale of the greenhouse, then prepare the land for the greenhouse. After preparation, water the soil and let it stand for 1-2 days;

[0007] S2: Use a rotary tillage seeder to perform micro-rotational tillage and sowing, and the sowing direction is spot sowing;

[0008] S3: After the fungus is sown, immediately place a nutrient bag on top of the sown fungus, cut two 5-10cm openings on one side of the nutrient bag with a knife, and make the openings fully contact the fungus sown on the soil to ensure that the hyphae grow into the soil and the nutrient bag at the same time;

[0009] S4: Cover the ground with film and build a small shed to provide a suitable growing environment until the mushrooms grow.

[0010] As a further technical solution, in step S1, the fungus strain refers to the mother strain of Morchella inoculated into the fungus strain base material so that the fungus strain base material is full of mycelium, and the formula of the fungus strain base material is consistent with that of the nutrient material in the nutrient bag.

[0011] As a further technical solution, the formula mass ratio of the bacterial base material and the nutrients in the nutrient bag is: 30%-40% wheat bran, 25%-35% rice husk, 15%-25% xylitol residue, 8%-12% rice bran, 5%-15% corn straw, 2%-4% chicken manure organic fertilizer, 0.5%-3% glucose, 0.5%-2% lime, 0.8%-1.5% gypsum, and the balance is water.

[0013] As a further technical solution, the formula mass ratio of the bacterial base material and the nutrients in the nutrient bag is: 40% wheat bran, 25% rice husk, 25% xylitol residue, 12% rice bran, 15% corn stalks, 4% chicken manure organic fertilizer, 3% glucose, 2% lime, 1.5% gypsum, and the balance is water.

[0014] As a further technical solution, the formula mass ratio of the bacterial base material and the nutrients in the nutrient bag is: 35% wheat bran, 30% rice husk, 20% xylitol residue, 10% rice bran, 10% corn straw, 3% chicken manure organic fertilizer, 1% glucose, 1% lime, 1% gypsum, and the balance is water.

[0015] As a further technical solution, in step S2, the front end of the rotary tillage seeder tills the soil, and the soil is leveled immediately after tillage. The upper end of the rotary tillage seeder is loaded with 200 kilograms of granular bacteria, and the lower end of the machine evenly sows the bacteria on the soil surface.

[0016] As a further technical solution, in step S2, the sowing width of the rotary tillage seeder is 100 cm, and during spot sowing, each sowing position is spaced 40 cm front and back and 25 cm left and right, and 3-5 grams of bacteria are sown at each location.

[0017] As a further technical solution, 4 grams of bacteria are sown at each location.

[0018] As a further technical solution, the nutrition bag is a plastic bag with a size of 18*36cm, and the bag contains 500g of nutrition material.

The present invention adopts new strain base material and nutrition bag formula, does not use food crop wheat as raw material, does not need to consume staple food, reduces cultivation costs, and improves the yield of morels, and then improves the economic benefits of enterprises. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0021] The present invention discloses a method for cultivating Morchella edulis without grain, comprising the following steps:

[0022] S1: Prepare the strain and nutrient bags according to the scale of the greenhouse, and then prepare the greenhouse land. The existing method is used for land preparation. After land preparation, the soil is watered and left to stand for 1-2 days. In this step S1, the strain refers to inoculating the mother strain of Morchella into the strain base material so that the strain base material is covered with hyphae to form the strain. The preparation of the strain adopts the existing method.

[0023] The formula of the nutrient material in the nutrient bag is consistent with that of the nutrient material in the nutrient bag. Of course, the formula of the nutrient material in the nutrient bag may be different from that of the nutrient material in the nutrient bag. The nutrient components in the nutrient bag may be similar in shape. The present invention does not make any special limitation on this. In the following embodiments, the formula of the nutrient material in the nutrient bag is consistent. The nutrient bag is a plastic bag with a size of 18*36cm, which contains 500g of nutrient material.

[0024] The invention no longer adopts the original strain base material and nutrient bag mainly based on wheat, but improves the formula of the strain base material and the nutrient material in the nutrient bag. The formula mass ratio of the strain base material and the nutrient bag is: 30%-40% of wheat bran, 25%-35% of rice husk, 15%-25% of xylitol residue, 8%-12% of rice bran, 5%-15% of corn straw, 2%-4% of chicken manure organic fertilizer, 0.5%-3% of glucose, 0.5%-2% of lime, 0.8%-1.5% of gypsum, and the balance is water. Since the water content of each of the above components itself is unstable, the amount of water added when the formula is prepared is not limited. When preparing the formula, the above components are uniformly mixed and ground, and then appropriate amount of water is added to stir evenly, and then sterilized at high temperature to make it into a block shape containing a certain humidity that is easy to break, and then it is used as the strain base material and nutrient material.

[0025] In this formula, wheat bran, rice husk, xylitol residue, and corn stalks can utilize their rich nutrients to promote and ensure the growth of Morchella throughout the entire cycle; and using xylitol residue as the strain base material and nutrient material can adjust the temperature and humidity in the soil and the nutrient bag, avoid high temperature and humidity and poor ventilation, and corn stalks are also easy to breathe, so that the Morchella has good air permeability during growth; chicken manure organic fertilizer and glucose can promote the rapid growth of Morchella hyphae in the early stage, and rice bran contains rich polysaccharides, which improves the necessary nutrients for the high-quality growth of Morchella. Lime and gypsum can sterilize and disinfect the strain base material and nutrient material before inoculation, and make the strain base material and nutrient material slightly condensed and formed, which is convenient for the sowing of strains and the shape maintenance of the nutrient material in the nutrient bag.

[0026] S2: Use a rotary tillage seeder for micro-rotary tillage and sowing. In this step S2, the strains cultivated in the previous step are first broken into wheat-sized particles so that they can be sown normally in the rotary tillage seeder. The front end of the rotary tillage seeder tills the soil, and the soil is leveled immediately after rotary tillage. The upper end of the rotary tillage seeder is filled with 200 kilograms of granular strains, and the lower end of the machine sows the strains evenly on the soil surface. The sowing width of the rotary tillage seeder is 100 cm. During sowing, each sowing position is spaced 40 cm in front and back and 25 cm in left and right. 3-5 grams of strains are sown at each location, and 4 grams of strains are preferably sown.

[0027] S3: After sowing the fungus, immediately place a nutrient bag on top of the sown fungus, cut two 5-10cm openings on one side of the nutrient bag with a knife, and make the openings fully contact the fungus sown on the soil to ensure that the hyphae grow into the soil and the nutrient bag at the same time;

[0028] S4: Cover the ground with film and build a small arch shed to provide a suitable growth environment until the mushrooms grow. Providing a growth environment means using existing environmental conditions such as temperature, humidity, light and ventilation to ensure the normal growth of morels.

[0029] Compared with the traditional cultivation method of morels, in which the fungus is sown and covered with soil, the nutrient bag can only be covered after the mycelium grows all over the soil surface one week later. In the cultivation method of the present invention, the fungus is directly sown on the soil surface, and the nutrient bag is immediately placed on the fungus. The mycelium grows and absorbs nutrients from the soil and the nutrient bag simultaneously, which can effectively improve the sowing efficiency. The fungus is reduced from the traditional 400 catties per mu to 80 catties per mu, saving about 80% of the fungus, reducing the cultivation cost, reducing the probability of nutrient bag contamination, and saving manual labor. Under the same sowing area, more than 30% of sowing labor can be saved.
