Description

Technical Field

[0001] The invention belongs to the technical field of plant planting, and particularly relates to a method for interplanting winter jujube, morel mushroom and stropharia. Background Art

[0002] The soil in Zhanhua area of ​​Shandong Province is highly salinized. Winter jujube trees are a common fruit in the area. In order to bring winter jujubes to market earlier and increase output value, more and more jujube farmers choose to build greenhouses for winter jujubes. However, from the end of winter jujube picking in October to May of the following year, the greenhouses are idle. The price of one acre of greenhouses is 40,000 to 50,000 yuan. If the greenhouses are idle, it will cause a waste of resources.

[0003] Stropharia is rich in nutrition, crisp and tender, with strong flavor. It usually grows on the edge of grassland or broad-leaved forest. It is widely distributed in Europe, North and South America and temperate Asia. It is usually planted in autumn. It can also be planted in Shandong, my country. It is cultivated around October. Before the Spring Festival, it will be full of mycelium, dormant in winter, and continue to grow after the Spring Festival. It can be picked in early April to early May. Morchella is a low-temperature fungus. It does not require high temperature to grow. It has high requirements for soil conditions and temperature. If it is not managed well, it will be completely extinct, so the price remains high.

[0023] The present invention provides a method for interplanting winter jujube, morel and stropharia, the method comprising the following steps: detecting and dividing the EC value of the soil for planting winter jujube trees, and dividing the soil when the average EC value is not higher than 1dS·m -1 The winter jujube trees of the present invention are planted in a greenhouse, and the winter jujube greenhouse is used to interplant morels and stropharia at the same time; the winter jujube greenhouse should be intact and ventilated. Rat repellent equipment is installed around to prevent rats from biting the nutrient bag and causing mycelium infection; the winter jujube trees have a plant spacing of 2m to 3m and a row spacing of 3m to 5m.

[0024] As a specific implementation method, after the winter jujube harvest is completed in October, weeds and crop waste between the tree rows are cleaned, highly dispersed alkaline floating soil is removed, and the ground is leveled. The soil between the tree rows is irrigated with tap water or fresh water to reduce the alkali. After the water infiltrates, the soil EC value is tested. If the average EC value is not higher than 1dS·m -1 Soil for growing morels, higher than 1dS·m -1 As a specific implementation method, morels and stropharia are planted from early November to late November, and stropharia are harvested in late March of the following year, and stropharia are harvested in early April.

[0025] When interplanting stropharia, the interplanting cultivation material of stropharia is a non-fermented interplanting cultivation material, which is corn cobs, cottonseed hulls and bran, and the mass ratio of corn cobs, cottonseed hulls and bran is 70:29:1; the interplanting cultivation material is evenly mixed and transported to the soil for planting stropharia to establish a bed; after the bed is built, it is irrigated with fresh water or tap water, and the bed is completely immersed in water, so that the cultivation material can absorb water thoroughly; after the water level drops, the stropharia is sown; the stropharia strains are broken into walnut-sized blocks and evenly sown on the cultivation material, and plum blossom sowing is adopted, with a hole distance of 10 to 12 cm and a depth of 10 cm. After covering with 3 to 5 cm corn cobs, a layer of non-alkaline soil with a thickness of 2 to 3 cm is covered. A black film is covered on the topsoil, and a vent hole with a hole diameter of about 2 cm is punched every 20 cm on the black film before covering. After that, field management of the stropharia is performed, including: spawn management and fruiting management. As an implementable method, spawn management includes: maintaining the moisture content of the culture medium at 65% to 70% and the temperature at 10°C to 25°C; fruiting management includes: when the mycelium in the culture medium is full and small buds appear on the surface of the covering soil, spray water once and keep the covering soil moist; the temperature of the culture medium is 13°C to 26°C and the moisture content is 60% to 70%; the lighting condition during the growth of the fruiting body is scattered light. As an implementation method, the variety of the stropharia is stropharia No. 2, purchased from Shandong Sansheng Wanwu Biotechnology Co., Ltd.

[0026] When interplanting morels, before planting morels, the soil where morels are to be planted is irrigated with fresh water or tap water; the purpose of the irrigation is to suppress alkali and further reduce the salt content; after the irrigation water seeps down, base fertilizer is spread on the bed surface, and the amount used is 2000kg / 667m special fertilizer for morels 2 , high potassium compound fertilizer 50kg / 667m 2 At the same time, 1.5kg / 667m 2 , Potassium dihydrogen phosphate 3kg / 667m 2 and phoxim 15kg / 667m 2Spread them together on the bed surface, and use a rotary tiller to till the soil once, to a depth of 20 cm. Water the soil sufficiently, and after the water seeps down, use a rotary tiller to turn the soil 1-2 times, to a depth of 20 cm. Before sowing, the soil EC value needs to be tested again. If the test value is higher than 1dS·m -1 , it is necessary to continue watering to reduce the alkali, and finally make the soil EC value lower than 1dS·m -1 Applying base fertilizer to the bed surface may cause the soil EC value to be higher than 1dS·m -1 If the soil EC value is appropriate, open the Morchella bag, crush the fungus, and use 1kg / 667m 2 , spread on the ground. Cover the soil with 3-5cm and then cover with a perforated black film. The size of the holes is consistent with that of the black film of the giant stropharia. Use bamboo strips to set up a large arch shed. The width of the arch shed is 1.5m and the height is 1.8m. The outside of the large arch shed is first covered with an 8-needle interwoven or 6-needle encrypted black shade net, and then covered with a transparent film. The transparent film and the shade net can be naturally in contact. The iron wire passes through the two and is tied to the bamboo strips of the large arch shed. The lower end is pressed with bricks, etc.; the shade net is first covered on the outside of the large arch shed and then covered with a transparent film to increase the temperature in the shed for the growth of mycelium. 7-15 days after sowing, when the mycelium fills the bed surface, place the external aid nutrient bag, place the black film on one side, and use tools to cut 2-3 long holes in the nutrient bag longitudinally, with a length of 80%-90% of the length of the nutrient bag. Place it with the hole opening facing down, and press it when placing it, so that the nutrient bag is close to the bed surface, so that all the holes are in contact with the soil without being exposed to the air. The nutrient bags are placed horizontally 15 cm away from the edge of the ridge, with a vertical spacing of 40 cm, and 2 to 3 rows are placed at equal distances in each ridge. After placement, cover the nutrient bags with black film. After that, field management of the morels is carried out, which includes: temperature and humidity control, light control, and later watering of mushrooms; as a specific implementation method, the optimum temperature for mycelium growth controlled by temperature and humidity is 10 to 18 ° C, the mycelium grows slowly below 5 ° C, and the mycelium is sparse and easy to die when it is above 20 ° C. The optimum temperature for fruiting body development is 15 to 20 ° C, and it is not easy to form primordia when the temperature is above 20 ° C. Both temperature and humidity are adjusted through vents. As a specific implementation method, when controlling light, it is necessary to select a black sunshade net with a good shading rate, and select a black sunshade net with 8-needle interlacing or 6-needle encryption. As a specific implementation method, the mushroom-inducing method is to spray until the soil is completely wet without water accumulation, then keep the soil surface moist, and spray water when the bed surface lacks water; control the ground temperature at 8-12°C, and keep the temperature difference between day and night at 8-10°C; and control the relative humidity of the air at 85%-90%. As an implementation method, the variety of the morel is Qimei, purchased from Shandong Junsheng Biotechnology Co., Ltd. As an implementation method, after the mushrooms are inducing, a small arch shed is set up with bamboo pieces, that is, the black film set up before is supported by bamboo pieces, and other methods of support operation can also be used to achieve the purpose of preventing the young mushrooms from contacting the black film. The sunshade net outside the large arch shed and the transparent film are interchanged inside and outside; the purpose of the interchange is to block the sunlight and reduce the temperature in the shed.

[0027] Unless otherwise specified, the experimental methods used in the following examples are all conventional methods; the materials and reagents used are reagents and materials that can be obtained from commercial channels unless otherwise specified.

[0028] The technical solutions provided by the present invention are described in detail below in conjunction with the embodiments, but they should not be construed as limiting the protection scope of the present invention.

[0029] Example 1

[0030] Soil screening for growing morels and stropharia

[0031] 1. Planting variety selection

[0032] The variety of morel selected was Qimei, purchased from Shandong Junsheng Biotechnology Co., Ltd.; the variety of Stropharia cap mushroom cultivated was Stropharia cap mushroom No. 2, purchased from Shandong Sansheng Wanwu Biotechnology Co., Ltd.

[0033] 2. Screening method

[0034] In order to explore the optimal soil EC value range for the growth of Morchella and Stropharia, the two were planted in soils with different EC values. The specific operations were as follows:

[0035] Soil was dug from the rows of the winter jujube greenhouse of the National Agricultural Science and Technology Park Management and Service Center in Binzhou, Shandong Province, and tested using the multifunctional digital soil EC tester of Zhengda Instruments. The collected soil was set to 0.2 dS·m -1 、0.4dS·m -1 、0.6dS·m -1 、0.8dS·m -1 、1.0dS·m -1 , 1.2S·m -1 、1.4dS·m -1 、1.6dS·m -1 .

[0036] 2. Results

[0037] The growth of Stropharia rugosa planted in soils with different EC values ​​is shown in Table 1.

[0038] Table 1 Growth of Stropharia rugosa planted in soils with different EC values

[0039]

[0040] As shown in Table 1, under different EC values, as the EC value continues to increase, the growth potential of Stropharia gradually decreases. This is reflected in the mycelium changing from dense to sparse, the color becoming lighter, and the other indicators also showing a downward trend. EC value higher than 1.2dS·m -1 After that, the growth rate and cap diameter were significantly affected. In general, as the EC value continued to increase, the growth of Stropharia cap continued to decline, and the fresh weight of a single mushroom continued to decrease. It can be inferred that if the EC value continues to increase, the mycelium of Stropharia cap will not germinate.

[0041] The growth of Morchella grown in soils with different EC values ​​is shown in Table 2.

[0042] Table 2 Growth of Morchella in soils with different EC values

[0043]

[0044] From the analysis of Table 2, we can see that as the EC value in the soil increases, the growth potential of Morchella is weakened. -1 ~1.6dS·m -1 The mycelium of Morchella did not germinate. The soil EC value was higher than 1.0dS·m -1 The morphology of the mushroom was poor, the characteristic smell gradually disappeared, and the cap length, cap diameter, and single mushroom fresh weight indicators decreased accordingly, and were significantly correlated with the EC value. Ultimately, the proportion of large mushrooms was less than half, which seriously affected the commercial quality and economic benefits.

[0045] Based on the above results, it can be seen that the EC value of Stropharia rugosodium is higher than 1.2dS·m -1 After that, EC value had a significant effect on growth rate and cap diameter. -1 and salinity less than 1.0dS·m -1 The growth conditions of the -1 The mycelium, mushroom morphology and the proportion of large mushrooms were all lower than 1.0dS·m -1 and the following results.

[0046] The unit price of Morchella is much higher than that of Stropharia, so the soil EC value is lower than 1.0dS·m -1 When the soil is higher than this value, choose to plant morels; for the soil with a higher value, you can plant giant mushrooms to maximize the benefits; the schematic diagram of the selection of planting areas according to soil salinity is as follows Figure 1 shown.

[0047] Example 2

[0048] A method for planting morels and strophariae simultaneously in a winter jujube greenhouse in saline-alkali land facilities comprises the following steps:

[0049] a) Selection of greenhouses for growing winter jujubes: The greenhouses for growing winter jujubes should be intact and ventilated. Rat repellent equipment should be installed around them to prevent rats from biting the nutrient bags and causing mycelium infection.

[0050] b) Site establishment: The spacing between winter jujube trees is 2m to 3m, and the row spacing is 3m to 5m.

[0051] According to the above-mentioned row spacing range of winter jujube trees, the row spacing here is 4m, the width is 5 rows, there are 4 available blank planting areas in the middle (the area between two rows of winter jujube trees), and the length is 667m 2 / (4×4)=41.7m; Since leaves grow outward, after projection from top to bottom, the width between each two rows of trees without branches and leaves is about 1.5m, so the land utilization rate of the winter jujube greenhouse can be calculated as: 1.5×4×41.7 / 667m 2 = 37%. Therefore, the utilization rate of the land under the winter jujube greenhouse is about 30% to 40%, that is, one mu of winter jujube greenhouse has about 0.3 mu of available land.

[0052] After the winter jujube harvest is finished, weeds and crop waste between the tree rows are cleaned up, highly dispersed alkaline loose soil is removed with a shovel, and the ground is leveled. The soil between the tree rows is irrigated with tap water or fresh water to suppress the alkali. After the water infiltrates, the soil EC value is tested with a portable soil EC monitor, and the average value is measured at multiple points; it is not higher than 1dS·m -1 Soil for growing morels, higher than 1dS·m -1 The soil is suitable for growing Stropharia. Different plots are marked to prevent confusion. Soil ridges are set on both sides of the plot to facilitate irrigation.

[0053] Through measurement, the winter jujube greenhouse was divided into sections to plant morels and stropharia according to the above different EC values. The area of ​​morels: the area of ​​stropharia = 2:1.

[0054] c) Interplanting of Stropharia: The interplanting cultivation materials are corn cobs, cottonseed hulls and bran. The mass ratio of corn cobs, cottonseed hulls and bran is 70:29:1, and it is not fermented. The above cultivation materials are mixed evenly and transported to the planting area to establish a bed. Stropharia is planted in the bed. The bed is set between two rows of winter jujube trees. The length of the bed is determined according to the measured soil EC value, and the width is determined according to the distance between the trees. It is generally 1.5m and the thickness is 25cm. After the cultivation material forms a bed, it is irrigated with large water (fresh water or tap water). The bed is completely immersed in water to facilitate the cultivation material to absorb the water. After the water level drops, Stropharia is planted. The Stropharia No. 2 (purchased from Shandong Sansheng Wanwu Biotechnology Co., Ltd.) strain is broken into walnut-sized pieces and evenly sown on the cultivation material. Plum blossom sowing is adopted, with a hole distance of 10 to 12 cm and a depth of 10 cm. After covering with 3-5cm corn cobs, cover with a layer of non-alkaline soil with a thickness of 2-3cm. Cover the soil with black film, and use a hole puncher to punch a ventilation hole with a diameter of about 2cm every 20cm before covering the black film. Then, field management of the Stropharia was carried out, including: spawn management and fruiting management.

[0055] The management of fungus growth includes: maintaining the moisture content of the culture medium at 65% to 70% and the temperature at 10℃ to 25℃;

[0056] The management of mushroom production includes: when the mycelium in the cultivation material is full and small buds appear on the surface of the covering soil, spray water once and keep the covering soil moist; the temperature of the cultivation material is 13℃~26℃, and the moisture content is 60%~70%; the lighting conditions during the growth of the fruiting body are scattered light.

[0057] d) Interplanting of Morchella: Before planting Morchella, use fresh water or tap water to irrigate the area where Morchella is to be planted to reduce the alkali and further reduce the salt content. The width of the mushroom bed is 1.5m, which is the same as the width of the Stropharia rugosa bed, and the length is determined according to the measured soil salinity.

[0058] The average soil EC value is not higher than 1dS·m -1 When planting morels on soil with high humidity, after the irrigation water seeps down, spread the base fertilizer on the surface of the bed: the special fertilizer for morels (purchased from Shijiazhuang Zhengding County Liutian Biological Organic Fertilizer Co., Ltd.) is used at a dosage of 2000kg / 667m 2 , high potassium compound fertilizer (purchased from Shandong Nuopuwo Import and Export Co., Ltd.) at a dosage of 50kg / 667m 2 At the same time, 1.5kg / 667m 2 , Potassium dihydrogen phosphate 3kg / 667m 2 and phoxim 15kg / 667m 2 Spread them together on the bed surface, and use a rotary tiller to till the soil once to a depth of 20 cm. Water the soil sufficiently, wait for the water to seep in, and then use a rotary tiller to turn the soil 1 to 2 times to a depth of 20 cm.

[0059] Before sowing, the soil EC value should be tested again. If it is higher than the test value by more than 1dS·m -1 , it is necessary to continue watering to reduce the alkali, and finally make the soil EC value lower than 1dS·m -1 .

[0060] Soil EC value is less than 1dS·m -1 After that, open the morel bag, crush the fungus, and use 1kg / 667m 2 , spread on the ground. After covering with 3-5cm of soil, cover with perforated black film. Perforated black film means using a puncher to punch a ventilation hole with a diameter of about 2cm every 20cm before covering. Use bamboo pieces to set up a large arch shed. The width of the arch shed is 1.5m and the height is 1.8m. The outside of the large arch shed is first covered with 8-needle interlaced or 6-needle encrypted black sunshade net, and then covered with transparent film. The transparent film and the sunshade net can be naturally in contact. The iron wire passes through the two and is tied to the bamboo pieces of the large arch shed. The lower end is pressed with bricks; the sunshade net is first covered on the outside of the large arch shed and then covered with transparent film to increase the temperature in the shed for the growth of mycelium.

[0061] 7-15 days after sowing, when the mycelium fills the bed surface, place the foreign aid nutrient bag, place the black film on one side, and use tools to cut 2-3 long holes in the foreign aid nutrient bag longitudinally, with a length of 80%-90% of the length of the foreign aid nutrient bag. Place it with the hole opening facing down, and press it when placing it, so that the foreign aid nutrient bag is close to the bed surface, so that all the holes are in contact with the soil without being exposed to the air. The nutrient bag is placed horizontally 15cm away from the edge of the bed, with a longitudinal spacing of 40cm, and 2-3 rows are placed at equal distances in each bed. After placing, cover the black film on the nutrient bag. Then carry out field management of morels, which includes: temperature and humidity control, light control, and later watering of mushrooms.

[0062] Temperature and humidity control: The optimum temperature for mycelium growth is 10-18℃. The growth rate is slow below 5℃, and the mycelium is sparse and easy to die above 20℃. The optimum temperature for fruiting body development is 15-20℃. It is difficult to form primordium when the temperature is above 20℃. Both temperature and humidity are adjusted through vents.

[0063] Light control: Scattered light is an objective condition for the development of morel hyphae and fruiting bodies. Morel hyphae are prone to withering and stagnant development under short-term direct light, and fruiting bodies are prone to premature cracking of gills under direct sunlight, affecting expansion. Therefore, it is necessary to choose a black sunshade net with a good shading rate, that is, a black sunshade net with 8-needle interlacing or 6-needle encryption.

[0064] Mushroom induction: spray until the soil is completely wet without water accumulation, then keep the soil surface moist, spray water when the bed surface lacks water; control the ground temperature at 8-12℃, keep the temperature difference between day and night at 8-10℃; control the relative humidity of the air at 85%-90%. After mushroom induction, use bamboo strips to set up a small arch shed, that is, use bamboo strips to support the previously set black film, or use other methods to support the operation so that the young mushrooms do not come into contact with the black film. Swap the sunshade net and transparent film outside the large arch shed; the purpose of the swap is to block the sunlight and reduce the temperature inside the shed.

[0065] According to the different soil EC values ​​between the rows of the winter jujube greenhouse, the plots were divided to plant morels and stropharia. Stropharia was planted in early November and morels in late November. Both were managed in the field, and stropharia were harvested in late March and early April of the following year.

[0066] By adopting the planting method of the present invention, the actual utilization area in the greenhouse is 3 mu, of which the planting area of ​​morels is 2 mu and the planting area of ​​stropharia is 1 mu. The stropharia and morels grow well and meet the requirements of first-class commercial mushrooms. The growth conditions are as follows: Figure 2 and Figure 3 The actual output of Morchella was 836kg, and that of Stropharia was 723kg; according to the unit price at that time: the average price of fresh Morchella was 90 yuan / kg, and the average price of Stropharia was 10 yuan / kg, the total output value was 82,500 yuan.

[0067] Although the above embodiment describes the present invention in detail, it is only a part of the embodiments of the present invention, not all of the embodiments. People can also obtain other embodiments based on this embodiment without creativity, and these embodiments all fall within the protection scope of the present invention.

4. The method according to claim 3, characterized in that: The bed is built with Stropharia capitis cultivation material, which is corn cobs, cottonseed hulls and bran, with a mass ratio of corn cobs, cottonseed hulls and bran of 70:29:

1. The Stropharia capitis cultivation material is not fermented.

5. The method according to claim 3, characterized in that: After the bed is built, it is irrigated with fresh water or tap water to immerse the entire bed in water so that the cultivation material can absorb water thoroughly; after the water level drops, the Stropharia cap mushrooms are sown.

6. The method according to claim 5, characterized in that: The sowing is to break the Stropharia occidentalis No. 2 strain into walnut-sized blocks and evenly sow them on the cultivation material, using plum blossom sowing, with a hole distance of 10 to 12 cm and a depth of 8 to 12 cm.

7. The method according to claim 1, characterized in that: Planting of morels is carried out in the bed, the width of the bed is determined by the distance between trees and is 1.2 to 1.5 m, and the thickness is 25 to 30 cm. Before planting morels, the soil where morels are to be planted is irrigated with fresh water or tap water.

8. The method according to claim 7, characterized in that: After the irrigation water seeps down, the base fertilizer is spread on the bed surface. The base fertilizer includes a special fertilizer for morels and a high-potassium compound fertilizer. The amount of the special fertilizer for morels is 1000-2000kg / 667m 2 The dosage of the high potassium compound fertilizer is 40-50 kg / 667 m 2 At the same time, 1.5-3 kg / 667 m 2 , Potassium dihydrogen phosphate 3~5kg / 667m 2 and phoxim 15~20kg / 667m 2 Sprinkle together on the bed surface.
