Description

Technical Field

[0001] The invention relates to the field of agricultural fertilizers, and in particular to a special fertilizer for cultivating dandelions under forests. Background Art

[0002] As an innovative agricultural development model, the forest economy relies on the natural ecological conditions of the forest land, fully taps the potential of forest land resources and shaded space, and builds a multi-level, multi-industry three-dimensional management system under the protection of the forest canopy, aiming to achieve efficient resource integration, complementary advantages and sustainable circular development. Among them, the forest medicine planting model is particularly prominent. It cleverly optimizes the horizontal and vertical structure and time dimension by carefully planning the time overlap and spatial layout of different plants in the growth cycle, effectively solving the problem of idle resources of large tracts of idle land under the forest, providing farmers with a new way to quickly increase their income, and significantly improving the comprehensive economic benefits of forest land.

[0003] Dandelion, a perennial herbaceous plant of the Asteraceae family, also known as Huadiding and Dandelion, particularly prefers a cool climate environment. It is widely distributed in northern China and shows a strong ability to adapt to the environment. It is not only rich in carbohydrates, trace elements, high-quality protein, fat and multiple vitamins, but also contains a series of active ingredients beneficial to health, such as choline, inulin, caffeic acid, organic acids, glucosinolates, etc. These ingredients give dandelion multiple pharmacological effects such as diuresis, laxative, jaundice relief, and promotion of bile secretion. It has a good effect on the treatment of pharyngitis, gastritis, enteritis and other diseases. At the same time, its inhibition of ringworm and anti-tumor effects have also attracted much attention.

[0004] In the current practice of understory dandelion cultivation, insufficient light conditions have a significant adverse effect on the growth of dandelions. Specifically, this low light environment leads to a longer growth period of dandelions and abnormally high water content, which in turn weakens the plant's resistance to stress and ultimately has an adverse effect on yield, especially a decrease in total flavonoid content, which makes it impossible to achieve the purpose of dandelion production.

[0005] In addition, in the current dandelion cultivation process, the use of chemical fertilizers and organic fertilizers has also exposed a series of problems. The application amount of these two fertilizers is difficult to control accurately, which often leads to a compacted soil structure (i.e. soil compaction). In severe cases, seedling burn may even occur. This is obviously contrary to the concept of ecological cultivation and cannot meet the special requirements of dandelion growth for the soil environment. That is, the existing fertilizer use strategy urgently needs to be optimized to better adapt to the ecological cultivation needs of dandelions, thereby promoting their healthy growth and improving yield and quality. Summary of the invention

[0006] In order to make up for the deficiencies of the above-mentioned prior art, the purpose of the present invention is to propose a special fertilizer for cultivating dandelions under forests, which can reduce the total amount of allelopathic phenolic acids in the soil under forests, increase the richness and diversity of microbial populations in the soil, and improve dandelion yield and total flavonoids content in the roots.

[0007] The object of the present invention is achieved through the following technical scheme, a special fertilizer for cultivating dandelions under forests, the technical main points of which are: The preparation method of the special fertilizer is as follows: 30-50 parts of corn cobs, 30-50 parts of wheat bran, 20-30 parts of fulvic acid, and the dosage of microbial agent is 10-15 parts per ten thousand; the microbial agent is 40-60 parts of Bacillus subtilis and 40-60 parts of Trichoderma viride, and the number of bacteria is 5-10×10 8 cfu / mL; the above materials are fermented, the fermentation pile height is 1.2-1.5m, plastic film is used to keep moisture in the early stage of fermentation, and it is turned over when the temperature rises to 55-65℃, and it is turned over once every 24-48 hours. After 10-15 days, the fermentation is completed to obtain special fertilizer.

[0008] The application method of the special fertilizer for cultivating dandelions under the forest is: mixing it with the soil in the planting ditch during sowing, and the mixing ratio is special fertilizer: soil = 1:10-20.

[0009] Beneficial effects of the present invention: (1) Special fertilizers have a significant effect on improving the soil structure, physical and chemical properties and nutrient content under the forest, which directly affects the growth of dandelions and increases their yield; (2) The total flavonoids content in dandelion leaves and roots was increased. When dandelions generally entered the seed maturity stage, the total flavonoids content in the leaves was higher than that in the roots. DETAILED DESCRIPTION

[0010] The technical solution of the present invention is described in detail below in conjunction with specific examples: 1. Biological bacteria materials Bacillus subtilis (Shandong Yiwu Biotechnology Co., Ltd.); Trichoderma viride (Shandong Nuojie Biotechnology Co., Ltd.); 2. How to use special fertilizer Preparation of special fertilizer: 40 parts of corn cobs, 40 parts of wheat bran, 20 parts of fulvic acid, and the dosage of microbial agent is 10 parts per 10,000; the microbial agent is 50 parts of Bacillus subtilis and 50 parts of Trichoderma viride, and the bacterial count is 10×10 8 cfu / mL; the above materials are fermented, the fermentation pile is 1.2m high, plastic film is used to keep moisture in the early stage of fermentation, and it is turned over when the temperature rises to 65℃, and turned over once every 48 hours. After 12 days, the fermentation is completed to obtain special fertilizer; when sowing, it is mixed with the soil in the planting ditch, and the mixing ratio is special fertilizer: soil = 1:15.

[0011] 3. Results Survey The application of special fertilizers has a certain effect on the total flavonoid content of dandelion leaves and roots, effectively increasing the total flavonoid content of leaves and roots. Moreover, when dandelions generally enter the seed maturity stage, the total flavonoid content in leaves is higher than that in roots. The total flavonoid content of dandelion leaves without special fertilizers is 32.44 mg / g, which is significantly lower than the total flavonoid content of dandelion leaves with special fertilizers (52.21 mg / g), while the total flavonoid content of roots treated with special fertilizers is 35.33 mg / g, which is significantly higher than the total flavonoid content of dandelion roots without special fertilizers (28.12 mg / g).

[0012] The yield of dandelions without special fertilizer treatment is: fresh leaf yield 483.4kg / kg / 667m 2 , fresh root yield 401.5kg / 667m 2 The yield of dandelions treated with special fertilizer is: fresh leaf yield 631.5kg / kg / 667m 2 , fresh root yield 542.1kg / 667m 2 That is, the special fertilizer increases the production yield of dandelions under the forest.
