Description
Technical Field
[0001] This invention belongs to the field of forage cultivation technology, specifically a formula combination for increasing the yield of hydroponic forage and its application. Background Technology
[0002] Hydroponics is a modern forage production technology that cultivates forage seedlings using nutrient solutions or water under controlled environmental conditions. This technology boasts significant advantages such as a short growth cycle, high yield per unit area, high water resource utilization, and no limitations imposed by soil or season. It has become an important way to solve the problem of supplying high-quality green fodder in areas with scarce land resources and for large-scale livestock farms.
[0003] Current hydroponic forage cultivation techniques mostly employ single-variety planting, or while mixed planting is involved, a lack of scientific variety matching and proportion design is required. Different forage varieties exhibit significant differences in germination rate, growth rhythm, root development, nutrient requirements, and disease resistance under hydroponic conditions. Blindly mixing varieties may lead to problems such as asynchronous germination, uneven growth, root competition, or cross-infection of diseases, thereby reducing overall yield and nutritional quality.
[0004] Therefore, there is an urgent need for a formula combination to increase the yield of hydroponic forage and its application. Summary of the Invention
[0005] To address the technical problem, this invention provides a formula combination for increasing the yield of hydroponic forage and its application, as detailed below: A formulation for increasing the yield of hydroponic forage, wherein the formulation is selected from any of the following by weight ratio: Ryegrass / barley / oats 60%-80% + chicory 20%-40%.
[0006] Preferably, the formulation combination is selected from any one of the following, based on mass ratio: Ryegrass 70% + Chicory 30%; 70% barley + 30% chicory; Oatmeal 70% + chicory 30%.
[0007] On the other hand, the present invention provides the application of the aforementioned yield-increasing hydroponic forage formula combination, which is applied to hydroponic forage production to improve the overall nutritional value of hydroponic forage.
[0008] Preferably, the comprehensive nutritional value includes at least one of the following: fresh grass yield, crude protein content, crude fat content, and mineral content.
[0009] Preferably, the hydroponic forage production includes the following steps: (1) Magnetic field treatment: Place the grass seeds in the formula combination in a magnetic field with a strength of 100-300mT for 40-50min; (2) Ultrasonic treatment: Place the grass seeds treated with magnetic field in an ultrasonic cleaner and treat them for 15-25 minutes at a frequency of 30-50kHz and a power of 100-150W. (3) Remove impurities from grass seeds: Remove impurities and unsaturated seeds from the grass seeds in the formula combination; (4) Seed soaking: Soak the grass seeds after removing impurities with hypochlorous acid. The soaking time should be extended in a timely manner according to the seed size to ensure that the seeds fully absorb water and kill insect eggs. (5) Seedling tray treatment: The seedling tray is sterilized with hypochlorous acid, and then the soaked grass seeds are spread evenly on the seedling tray; the seedling tray is spread in a single layer with dense particles, and should not be too thick to ensure that the seedling tray is permeable to water and air and does not rot. (6) Germination of seedlings: Place the seedling trays with grass seeds in a diffused light environment for cultivation until germination and emergence; (7) Growth in the tower: Remove the non-woven fabric from the germinated seedling trays and place them in the spiral grass tower. Water them with a sprinkler for 7-8 days to obtain the finished hydroponic forage.
[0010] Preferably, in step (1), impurities and unsaturated seeds of the grass seeds in the formula combination are removed by sedimentation and stratification.
[0011] Preferably, in step (4), the grass seeds after impurity removal are soaked in hypochlorous acid for 16-20 hours.
[0012] Preferably, in step (6), the diffused light environment is: a diffused light environment with an illumination intensity of 3000-4000 Lux, a temperature controlled at 20-25℃, and a relative humidity of 60%-80%.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The beneficial effects of this invention are mainly reflected in the following aspects: 1. This invention significantly improves the crude protein, crude fat, and mineral content of hydroponic forage through reasonable variety matching and ratio, while reducing the content of crude fiber and acid detergent fiber. For example, in Experiment 1, the crude protein content of group T1 reached 30.51%, the crude fat content increased to 7.3%, while the crude fiber content was only 13.7% and the acid detergent fiber content was 14.1%. Compared with the single-variety control group, the nutritional composition was significantly improved.
[0014] 2. The forage formulation provided by this invention significantly improves the digestibility and palatability of forage due to the reduction in crude fiber and acid detergent fiber content, which helps to increase animal feed intake and feed utilization, thereby improving breeding efficiency.
[0015] 3. The content of mineral elements such as calcium, zinc, and iron in the formulation combination of the present invention is significantly higher than that in the single-variety control group. For example, the calcium content in the T1 group reached 7.9g / kg, the zinc content was 41.8mg / kg, and the iron content was 230.8mg / kg, all of which were significantly higher than those in the control group, providing more comprehensive nutritional support for the animals.
[0016] 4. This invention uses the NSI value as an indicator to comprehensively evaluate the nutritional value of hydroponic forage. The nutritional synergistic effect of different formulation combinations is evaluated by calculating (crude protein content × crude fat content) / (crude fiber content × acid detergent fiber content). Experimental data show that the NSI value of the formulation combination of this invention is significantly higher than that of the single-variety control group, which fully proves its effectiveness in improving the comprehensive nutritional value of hydroponic forage.
[0017] 5. In view of the lack of scientific matching and ratio design in the existing hydroponic forage planting of single varieties or mixed planting, the present invention provides a scientific hydroponic forage formula combination and its application method for increasing yield, which effectively solves problems such as asynchronous germination, uneven growth, root competition or cross-infection of diseases, and improves the overall yield and nutritional quality.

[0062] III. Experimental Results On day 7 of hydroponic forage growth, three seedling trays were randomly selected from each treatment group as replicates.

The fresh forage samples were placed in a 105℃ oven for 25 minutes to blanch, then dried in a 65℃ constant temperature drying oven to constant weight. The samples were then pulverized and passed through a 40-mesh sieve for nutrient analysis. The results are shown in Tables 1-2.
[0063] Table 1. Results of nutrient composition analysis of hydroponic forage in each group of Experiment 1
[0064] Table 2. Results of nutrient composition analysis of hydroponic forage in each group of Experiment 2
[0065] The experimental results in Tables 1 and 2 show that the formulation combination provided by this invention significantly improves the overall nutritional value of hydroponic forage. Compared with the control groups, the crude protein content of groups T1, T2, and T3 reached 30.51%, 39.62%, and 42.23%, respectively, and the crude fat content increased to 7.3%, 7.7%, and 8.5%, respectively, all significantly higher than the single-variety and other mixed-ratio control groups. Simultaneously, the content of crude fiber and acid detergent fiber decreased significantly, with group T1 containing only 13.7% crude fiber and 14.1% acid detergent fiber, indicating a significant improvement in the digestibility and palatability of the forage. Furthermore, minerals such as calcium, zinc, and iron showed a clear enrichment trend in groups T1-T3. In summary, this invention achieves the goal of producing high-quality forage with high protein, high energy, high minerals, and low fiber from hydroponic forage.
[0066] The nutritional synergy index for each group was calculated as follows: (crude protein content × crude fat content) / (crude fiber content × acid detergent fiber content). Figure 1 : CK1: 0.065, CK2: 0.055, CK3: 0.045, CK4: 0.073, CK5: 0.080, CK6: 0.071, CK7: 0.077, CK8: 0.122, CK9: 0.179, CK10 :0.075, CK11: 0.066, CK12: 0.098, CK13: 0.179, CK14: 0.139, CK15: 0.119, CK16: 0.094, CK17: 0.113, CK18: 0.127; T1: 1.153, T2: 1.228, T3: 1.207.
[0067] The calculation results of the Nutritional Synergy Index (NSI) show that the formulation combination provided by this invention has a highly significant improvement in nutritional synergy. The NSI value of group T1 reached 1.153, group T2 reached 1.228, and group T3 reached 1.207, while the NSI values of all control groups were 0.179 or below, with most control groups below 0.15. This indicates that, through scientific variety matching and ratio design, this invention establishes a positive relationship between crude protein, crude fat, crude fiber, and acid detergent fiber, resulting in a significantly higher NSI value compared to single-variety and other mixed control groups. This fully demonstrates the outstanding effect of this formulation combination in improving the comprehensive nutritional value of hydroponic forage.
