A High-Efficiency Cultivation Method for Garlic, Mushrooms, and Beans with Four Harvests Per Year Based on Facility Vegetable Fields

Abstract

This invention discloses a highly efficient cultivation method for garlic, mushrooms, and soybeans in greenhouse vegetable fields, allowing for four harvests per year. Utilizing greenhouse vegetable fields, a crop of green garlic seedlings is intercropped with a crop of morel mushrooms, followed by a rotation of two crops of fresh soybeans. This allows for the harvesting of green garlic seedlings, morel mushrooms, and two crops of fresh soybeans within a year, increasing the multiple cropping index per unit area and achieving a highly efficient cultivation method with four harvests per year. The intercropping and rotation of garlic, mushrooms, and soybeans creates a virtuous cycle in the greenhouse vegetable field soil. The well-developed root system of green garlic seedlings can kill various harmful bacteria in the soil, facilitating the intercropping of morel mushrooms and producing garlic-flavored morel mushrooms. The abundant mycelium and mushroom stems remaining in the soil after the morel mushroom harvest, along with exogenous nutrient bags, can serve as natural organic fertilizer, increasing soil organic matter content and providing a rich nutrient source for the growth of fresh soybeans. The biological nitrogen fixation by the rhizobia in fresh soybeans can improve the soil, and the secreted acids can activate insoluble phosphorus in the soil, increasing soil fertility, reducing the need for fertilizers and pesticides, and promoting the healthy production of the next crop of organic green garlic seedlings.

Description

Technical Field

[0001] This invention patent relates to a high-efficiency cultivation method for greenhouse vegetables, specifically a high-efficiency cultivation method based on garlic, mushrooms, and soybeans for four harvests a year in greenhouse vegetable fields. One crop of green garlic seedlings is intercropped with one crop of morel mushrooms, and two crops of fresh soybeans are rotated. This belongs to the field of greenhouse vegetable cultivation technology. Background Technology

[0002] Facility vegetable cultivation refers to farmland primarily used for year-round vegetable planting. Currently, the production environment of facility vegetable fields is relatively closed, and the types and varieties of vegetables grown are limited. Especially under conditions of heavy fertilization, heavy irrigation, and high-intensity cultivation, the soil has high levels of ammonia nitrogen and nitrite, making it prone to continuous cropping obstacles or salinization, resulting in a decline in planting efficiency. It is necessary to adopt technical measures such as high-temperature fumigation or fallowing in summer to restore the soil, reverse the land crisis, and restore high-quality cultivation. However, high-temperature fumigation or fallowing in summer can easily lead to a low multiple cropping index per unit area of ​​facility vegetable fields, low land utilization, low economic benefits, and an inability to form a green, low-carbon, and virtuous ecological cycle. Summary of the Invention

[0003] To address the challenges of efficient cultivation in greenhouse vegetable fields, this invention employs a seamless, year-round cultivation method involving wet and dry rotation within cold greenhouses. This method complements various vegetable varieties, increases soil fertility, reduces fertilizer and pesticide use, and creates a green and low-carbon ecological cycle under mixed cultivation in greenhouse vegetable fields. By intercropping a crop of green garlic seedlings with a crop of morel mushrooms and rotating with a second crop of fresh soybeans before the new year, this invention achieves a highly efficient cultivation method that allows for four harvests of garlic, mushrooms, and soybeans per year in greenhouse vegetable fields.

[0004] This invention is achieved by the following technical solution: a high-efficiency cultivation method for garlic, mushrooms and soybeans with four harvests a year based on facility vegetable fields. The method utilizes facility vegetable fields, with one crop of green garlic seedlings before the new year, one crop of morel mushrooms, and two crops of fresh soybeans in rotation. Green garlic seedlings, morel mushrooms and two crops of fresh soybeans can be harvested within a year, thereby increasing the multiple cropping index per unit area and achieving a high-efficiency cultivation method with four harvests a year.

[0005] As a preferred embodiment of the efficient cultivation method for garlic, mushrooms, and beans with four harvests per year in facility vegetable fields as described in this invention, the specific cultivation steps are as follows:

[0006] Step 1) First crop of garlic sprouts before the Lunar New Year: In early to mid-September, construct or select a cold-type production greenhouse with a spray system, shading facilities, and a skirt film. Select disease-resistant, high-yielding garlic sprout varieties, and conduct virus-free culture and off-site propagation; fertilize and adjust soil pH with quicklime, use wide and narrow rows with dense planting, soak in cold well water for 12-16 hours, ridge planting, seed treatment, and sowing, with a wide row spacing of 30cm, a narrow row spacing of 6cm, and a plant spacing of 3-4cm, at a density of 100,000-120,000 plants / acre; in high temperatures, spraying or shading can be used to promote garlic sprouting; in October, strengthen fertilizer and water management during the garlic sprout growth period, and regularly apply urea or spray with clean water;

[0007] Step 2) Intercropping with morel mushrooms: In mid-to-late November, while strengthening fertilizer and water management during the growth period of garlic sprouts, select disease-resistant and high-yielding morel mushroom varieties; sterilize morel mushroom spawn bags at high temperature, and intercrop them 15 days after inoculation; plant morel mushrooms in rows between garlic sprouts that have been sprayed with water at 3-20℃, with a sowing rate of 150-200 kg / mu, cover with 1-2 cm of soil, and cover with black mulch for shading and moisture retention; 7-10 days after sowing, when the mycelium has spread, place 1000 kg / mu of sterilized nutrient bags under the black mulch, and make 2-3 5-8 cm long cuts on one side of the nutrient bag, with the cuts facing down and close to the bed surface; in December, strengthen fertilizer and water management during the growth period of garlic sprouts and temperature and humidity management during the mycelium growth period of morel mushrooms;

[0008] In late January and early February of the following year, green garlic sprouts were harvested in batches and grades, with a yield of 1500-2000 kg / mu. More were harvested when the price was high and less were harvested when the price was low. After the green garlic sprouts were harvested, the 30cm narrow film was replaced with a 60cm wide film, and holes were made for ventilation. The morel mushrooms were managed in a low temperature, high humidity and shaded environment to form a large number of pale yellow morel sclerotia.

[0009] In February, strengthen the management of temperature, humidity and light for morel mushrooms. Increasing temperature, high humidity and shading are conducive to the formation of morel primordia. Water thoroughly to a depth of 25-30cm, cover with two layers of film to keep warm and moist, and primordia can be formed in 5-7 days. In case of severe cold air, the film inside the greenhouse can be removed to lower the temperature and delay the formation of morel primordia, so as to ensure the overall annual yield of morel mushrooms.

[0010] In March, pay attention to increasing temperature, maintaining humidity, and providing shade. Plan to harvest morel mushrooms in stages. Harvest when the cap turns from light brown to dark gray, indicating an age of 15-20 days. The cap ridge and pit should be clearly defined, and the flesh should be thick and elastic. Before harvesting, open ventilation openings to appropriately reduce the moisture content of the fruiting bodies and improve the quality of the morels. Use a knife to cut horizontally along the ground; do not pull directly by hand to avoid damaging the soil surface and affecting the growth of other morels. After harvesting, remove any attached soil and impurities from the mushrooms, stack them in order, and handle them gently to avoid scratching the surface and affecting the product's appearance. Expedite the morel drying process: set the shape and color at 35-36℃ for 3 hours; raise the temperature and reduce humidity at 38-39℃ for 4 hours; and remove moisture and preserve aroma at 36-37℃ for 3 hours.

[0011] Step 3) First crop of fresh soybeans in rotation: Morel mushrooms can be harvested 2-4 times in early to mid-April of the following year. The harvest period for heat-resistant varieties can be extended to mid-April, with a fresh mushroom yield of 900-1000 kg / mu. After harvesting, the large amount of mycelium, mushroom stems, and exogenous nutrient bags remaining in the soil should be used as natural organic fertilizer for tilling and land preparation. Select spring-sown fresh soybean varieties, treat seeds and sow them in mid-April. In late April, after the fresh soybeans emerge, pay attention to the selection of herbicides for spraying.

[0012] During the flowering period of fresh soybeans in late May, strengthen the management of spring-sown fresh soybeans during their growth period; during the pod-setting period of fresh soybeans in June, strengthen fertilizer and water management.

[0013] Step 4) Second crop of fresh soybeans in rotation: Spring-sown fresh soybeans are harvested at the end of June or the beginning of July of the following year, with high yield and efficiency, yielding 1500-2000 kg / mu; in mid-July, land is prepared, fertilizer is applied, and summer-sown fresh soybeans are sown, with seedlings emerging 10 days later, but the fresh soybeans have thin and long stems; in mid-August, fresh soybeans are in the pod-filling stage, and summer-sown fresh soybeans are harvested at the end of August, with high yield and efficiency, yielding 750-800 kg / mu.

[0014] As a preferred embodiment of the efficient cultivation method for garlic, mushrooms and beans with four harvests a year in facility vegetable fields as described in this invention: the green garlic seedlings are of the Pengzhou No. 1 or Pengzhou No. 2 variety.

[0015] As a preferred embodiment of the efficient cultivation method for garlic, mushrooms and beans with four harvests a year in facility vegetable fields as described in this invention: the morel mushroom variety is Su Morel Mushroom No. 1 or Su Morel Mushroom No. 2.

[0016] As a preferred embodiment of the efficient cultivation method for garlic, mushrooms and soybeans with four harvests per year in facility vegetable fields as described in this invention: the soybean variety is Xuchun No. 4 or Suxin No. 6.

[0017] Beneficial technical effects of the present invention:

[0018] This invention patent is based on the seamless integration of wet and dry crop rotation in greenhouse vegetable fields, enabling year-round production with high yields and efficiency. The dry cropping of garlic sprouts and two crops of fresh soybeans in greenhouse vegetable fields, combined with the wet cropping of morel mushrooms under low-temperature shade, allows for year-round harvesting of garlic sprouts, morel mushrooms, and two crops of fresh soybeans, increasing the multiple cropping index per unit area and achieving a highly efficient cultivation method with four harvests per year. In particular, the sale of greenhouse garlic sprouts at "New Year's prices" is a crucial foundation for increasing farmers' income and improving agricultural efficiency.

[0019] Intercropping and rotation of garlic, mushrooms, and soybeans create a virtuous cycle in greenhouse vegetable fields. The extensive root system of garlic sprouts in greenhouse vegetable fields acts as a natural "antibiotic" for the soil, killing various harmful bacteria and promoting the growth of less unwanted fungi in intercropped morel mushrooms, resulting in garlic-flavored morel mushrooms. The abundant mycelium and mushroom stems remaining in the soil after harvesting morel mushrooms, as well as the exogenous nutrient bags, can serve as natural organic fertilizer, increasing soil organic matter content and providing a rich source of nutrients for the growth of fresh soybeans. The biological nitrogen fixation of rhizobia in the rotation of fresh soybeans can improve the soil, and the acid secreted can activate insoluble phosphorus in the soil, increasing soil fertility, reducing the need for fertilizers and pesticides, and facilitating the healthy production of the next crop of organic garlic sprouts. The combination of garlic, mushrooms, and soybeans in soil fertility management creates a green and low-carbon ecological cycle in greenhouse vegetable cultivation. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below. This is only for explanation and does not limit the scope of protection of this invention. Example 1

[0021] Based on a high-efficiency cultivation method for garlic, mushrooms, and beans in greenhouse vegetable fields, yielding four harvests a year, the specific cultivation steps are as follows:

[0022] Step 1) First crop of garlic sprouts before the Lunar New Year: On September 5th, select a cold-type production greenhouse with a spray system, shade, and a skirt film; select the disease-resistant, high-yielding garlic sprout variety 'Pengzhou No. 1', and conduct virus-free culture and off-site propagation. Fertilize and adjust the soil pH with quicklime, use wide and narrow rows with dense planting, soak in cold well water for 14 hours, ridge planting, seed treatment, and sowing, with a wide row spacing of 30cm, a narrow row spacing of 6cm, and a plant spacing of 4cm, at a density of 100,000 plants / acre. If high temperatures occur, spraying or shading can be used to promote garlic sprouting; in October, strengthen fertilizer and water management during the garlic sprout growth period, and regularly apply urea or spray with clean water.

[0023] Step 2) Intercropping with Morel Mushrooms: On November 17th, under the premise of strengthening fertilizer and water management during the growth period of garlic sprouts, the disease-resistant and high-yielding morel mushroom variety 'Su Yangduojun No. 2' was selected; the morel mushroom spawn bags were sterilized at high temperature, and intercropping was carried out 15 days after inoculation. Morel mushrooms were planted in rows between garlic sprouts that were sprayed with water at 3-20℃, with a sowing rate of 180 kg / mu, covered with 1 cm of soil, and covered with black mulch for shade and moisture retention; 10 days after sowing, when the mycelium was fully distributed, 1000 kg / mu of sterilized nutrient bags were placed under the black mulch, with 3 5 cm long slits cut on one side of the nutrient bag, with the slits facing down and close to the bed surface. In December, fertilizer and water management during the growth period of garlic sprouts and temperature and humidity management during the mycelium stage of morel mushrooms were strengthened.

[0024] On January 26th of the following year, the green garlic sprouts were harvested in batches and grades, with a yield of 2000 kg / mu. Higher prices resulted in larger harvests, and lower prices in smaller ones. After harvesting the green garlic sprouts, the narrow (30cm) plastic film was replaced with a wider (60cm) film, with holes punched for ventilation. The morel mushrooms were managed under low temperature, high humidity, and shade conditions to promote the formation of abundant pale yellow morel sclerotia.

[0025] In February, strengthen the management of temperature, humidity, and light for morel mushrooms. Increased temperature, high humidity, and shading are conducive to the formation of morel primordia. Water thoroughly to a depth of 25-30 cm, cover with two layers of film for heat preservation and moisture retention, and primordia will form in 7 days. If a severe cold front occurs, the film inside the greenhouse can be removed to lower the temperature and delay the formation of morel primordia, so as to ensure the overall annual yield of morel mushrooms.

[0026] In March, pay attention to increasing temperature, maintaining humidity, and providing shade, and plan the harvesting of morel mushroom fruiting bodies in stages. Harvest when the cap turns from light brown to dark gray (15-20 days old), the ridge and pit of the cap are clearly defined, and the flesh is thick and elastic. Before harvesting, open ventilation openings to appropriately reduce the moisture content of the fruiting bodies and improve the quality of the morels. Use a knife to cut horizontally along the ground; do not pull directly by hand to avoid damaging the soil surface and affecting the growth of other morels. After harvesting, remove any attached soil and impurities from the mushrooms, stack them in order, and handle them gently to avoid scratching the surface and affecting the product's appearance. Expedite the morel drying process: set the shape and color at 35-36℃ for 3 hours; raise the temperature and reduce humidity at 38-39℃ for 4 hours; and remove moisture and preserve aroma at 36-37℃ for 3 hours.

[0027] Step 3) First crop of fresh soybeans in rotation: Morel mushrooms are harvested three times on April 6 of the following year. The harvest period for heat-resistant varieties is extended to mid-April, with a fresh mushroom yield of 1000 kg / mu. After harvesting, the large amount of mycelium and mushroom stems remaining in the soil, as well as the exogenous nutrient bags, are used as natural organic fertilizer for tilling and land preparation. The spring-sown fresh soybean variety 'Xuchun No. 4' is selected, and the seeds are treated and sown in mid-April. In late April, after the fresh soybeans emerge, herbicides should be sprayed.

[0028] During the flowering period of fresh soybeans in late May, strengthen the management of the growth period of spring-sown fresh soybeans; during the pod-setting period of fresh soybeans in June, strengthen fertilizer and water management.

[0029] Step 4) Second crop of fresh soybeans in rotation: On July 5th of the following year, spring-sown fresh soybeans were harvested, achieving high yield and efficiency, with a yield of 2000 kg / mu. On July 10th, land was prepared, fertilizer was applied, and summer-sown fresh soybean variety 'Suxin 6' was planted. On July 20th, the second crop of fresh soybeans emerged 10 days later, but the soybeans had thin and long stems. In mid-August, the fresh soybeans reached the pod-filling stage, and at the end of August, summer-sown fresh soybeans were harvested, achieving high yield and efficiency, with a yield of 750 kg / mu. Example 2

[0030] Based on a high-efficiency cultivation method for garlic, mushrooms, and beans in greenhouse vegetable fields, yielding four harvests a year, the specific cultivation steps are as follows:

[0031] Step 1) First crop of garlic sprouts before the Lunar New Year: On September 10th, construct a cold-type production greenhouse with a spray system, shade, and a plastic film skirt. Select the disease-resistant, high-yielding garlic sprout variety 'Pengzhou No. 2', and conduct virus-free culture and off-site propagation. Apply fertilizer and adjust the soil pH with quicklime. Use wide and narrow rows with dense planting. Soak the garlic sprouts in cold well water for 12 hours, then plant them in raised beds. Mix the seeds, sow them, with a wide row spacing of 30cm, a narrow row spacing of 6cm, and a plant spacing of 3cm, resulting in a density of 120,000 plants / acre. If high temperatures occur, spraying or shading can be used to promote garlic sprout emergence. In October, strengthen fertilizer and water management during the garlic sprout growth period, and regularly apply urea or spray with clean water.

[0032] Step 2) Intercropping with Morel Mushrooms: On November 22nd, under the premise of strengthening fertilizer and water management during the growth period of garlic sprouts, the disease-resistant and high-yielding morel mushroom variety 'Su Yangduojun No. 1' was selected. Morel mushroom spawn bags were sterilized at high temperature, and intercropping was carried out 15 days after inoculation. Morel mushrooms were planted in rows between garlic sprouts that were sprayed with water at 3-20℃, with a sowing rate of 200 kg / mu, covered with 2 cm of soil, and covered with black mulch for shade and moisture retention. Seven days after sowing, when the mycelium had fully developed, 1000 kg / mu of sterilized nutrient bags were placed under the black mulch. Two 8 cm long slits were made on one side of the nutrient bag, with the slits facing down and tightly against the bed surface. In December, fertilizer and water management during the growth period of garlic sprouts and temperature and humidity management during the mycelium stage of morel mushrooms were strengthened.

[0033] On January 22nd of the following year, the green garlic sprouts were harvested in batches and grades, with a yield of 1500 kg / mu. Higher prices resulted in larger harvests, and lower prices in smaller ones. After harvesting the green garlic sprouts, the narrow (30cm) plastic film was replaced with a wider (60cm) film, with holes punched for ventilation. The morel mushrooms were managed under low temperature, high humidity, and shade conditions to promote the formation of abundant pale yellow morel sclerotia.

[0034] In February, strengthen the management of temperature, humidity, and light for morel mushrooms. Increased temperature, high humidity, and shading are conducive to the formation of morel primordia. Water thoroughly to a depth of 25-30 cm, cover with two layers of film for heat preservation and moisture retention, and primordia will form in 5 days. If a severe cold front occurs, the film inside the greenhouse can be removed to lower the temperature and delay the formation of morel primordia, so as to ensure the overall annual yield of morel mushrooms.

[0035] In March, pay attention to increasing temperature, maintaining humidity, and providing shade, and plan the harvesting of morel mushroom fruiting bodies in stages. Harvest when the cap turns from light brown to dark gray (15-20 days old), the ridge and pit of the cap are clearly defined, and the flesh is thick and elastic. Before harvesting, open ventilation openings to appropriately reduce the moisture content of the fruiting bodies and improve the quality of the morels. Use a knife to cut horizontally along the ground; do not pull directly by hand to avoid damaging the soil surface and affecting the growth of other morels. After harvesting, remove any attached soil and impurities from the mushrooms, stack them in order, and handle them gently to avoid scratching the surface and affecting the product's appearance. Expedite the morel drying process: set the shape and color at 35-36℃ for 3 hours; raise the temperature and reduce humidity at 38-39℃ for 4 hours; and remove moisture and preserve aroma at 36-37℃ for 3 hours.

[0036] Step 3) Crop rotation: First crop of fresh soybeans: Morel mushrooms are harvested four times starting April 10th of the following year. For heat-resistant varieties, the harvest period is extended to mid-April, with a fresh mushroom yield of 900 kg / mu. After harvesting, the remaining mycelium, mushroom stems, and exogenous nutrient bags in the soil are used as natural organic fertilizer for tilling and land preparation. The spring-sown fresh soybean variety 'Xuchun No. 4' is selected, and seeds are treated and sown in mid-April. In late April, after the fresh soybeans emerge, herbicides should be applied.

[0037] During the flowering period of fresh soybeans in late May, strengthen the management of spring-sown fresh soybeans during their growth period. During the pod-setting period of fresh soybeans in June, strengthen fertilizer and water management.

[0038] Step 4) Second crop of fresh soybeans in rotation: On July 9th of the following year, spring-sown fresh soybeans were harvested, achieving high yield and efficiency, with a yield of 1500 kg / mu. On July 11th, land preparation, fertilization, and summer sowing of fresh soybean variety 'Suxin 6' (bred by the Jiangsu Academy of Agricultural Sciences, Crop Selection) were carried out. On July 22nd, the second crop of fresh soybeans emerged 10 days later, but the soybeans had thin and long stems. In mid-August, the fresh soybeans reached the pod-filling stage, and at the end of August, summer-sown fresh soybeans were harvested, achieving high yield and efficiency, with a yield of 800 kg / mu.
