Description

Technical Field

[0001] The invention belongs to the field of seedling cultivation, in particular to a method for producing forage barley hydroponic seedlings. Background Art

[0002] Hydroponics is an advanced soilless plant cultivation technology that uses nutrient solution instead of traditional soil to provide the necessary water, nutrients and oxygen for plant roots, thereby achieving healthy plant growth. Hydroponics has the advantages of short growth cycle, high yield, good quality and easy management, and has been widely used in modern agriculture.

[0003] Existing hydroponic facilities use ordinary greenhouses combined with sunshade nets, fill lights and other methods to adjust the light intensity and time, which can meet the light needs of barley in the early stage of growth to a certain extent. Temperature regulation relies on natural ventilation of the greenhouse, sunshade and cooling, and insulation and covering measures in winter. Humidity control often relies on ventilation and simple spray devices.

[0004] However, the use of greenhouses for hydroponics will lead to insufficient accuracy of environmental factors: existing greenhouse lighting adjustments are difficult to accurately control light intensity, and the light quality and intensity of the fill light are unevenly distributed, causing forage barley to grow slowly, resulting in thin and weak seedlings and uneven quality. In terms of temperature, natural ventilation and insulation covering measures cannot accurately maintain a suitable day and night temperature difference, affecting the accumulation of barley dry matter and reducing yield. Humidity fluctuates greatly, and high humidity can easily cause diseases, especially the growth of mold. Low humidity causes the plant to lose too much water through transpiration, which hinders growth, resulting in too slow growth and the emergence of diseases and insect pests.

[0005] To this end, those skilled in the art have proposed a method for producing forage barley hydroponic seedlings to solve the problems raised by the background technology. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a method for producing hydroponic forage barley seedlings to solve the problem in the prior art that the hydroponic forage barley seedlings grow too slowly and are prone to diseases and insect pests.

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 The present invention is a flow chart of the production of forage barley hydroponic seedlings. DETAILED DESCRIPTION

[0025] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1 As shown:

[0027] Embodiment 1: The present invention provides a method for producing forage barley hydroponic seedlings, comprising the following steps:

[0028] S1. Select healthy and plump forage barley seeds, rinse them repeatedly with clean water to remove impurities, shrunken grains and moldy grains;

[0029] Among them, by selecting healthy and plump seeds, the germination rate and growth potential of the seeds can be ensured, and poor growth of hydroponic seedlings caused by seed quality problems can be avoided. Washing with clean water can remove impurities, shrunken seeds and moldy seeds on the surface of the seeds, reduce the occurrence of diseases and pests in the subsequent growth process, and ensure the healthy growth of hydroponic seedlings.

[0030] S2. Soak the seeds in a hydrogen peroxide solution for disinfection, then rinse with clean water to remove the disinfectant;

[0031] Among them, hydrogen peroxide solution is a commonly used disinfectant with a broad-spectrum bactericidal effect. It can effectively kill pathogenic microorganisms on the surface of seeds. Using hydrogen peroxide solution to disinfect seeds can effectively kill bacteria and fungi on the surface of seeds and reduce the occurrence of diseases during hydroponics. Rinsing with clean water can remove residual disinfectants and avoid the negative impact of disinfectants on seed germination and growth.

[0032] S3, soaking the sterilized seeds in water for germination;

[0033] Among them, soaking and germination can make the seeds fully absorb water, activate the physiological activities inside the seeds, and promote seed germination. The appropriate soaking temperature and time provide the best germination conditions for the seeds, ensuring that the seeds can germinate quickly and evenly.

[0034] S4. Prepare the hydroponic container, clean and disinfect it;

[0035] Among them, cleaning and disinfecting hydroponic containers can remove dirt and germs on the surface of the containers, ensure the cleanliness of the hydroponic environment, and reduce the occurrence of diseases during the growth of hydroponic seedlings.

[0036] S5. Place two layers of gauze in the hydroponic container and add nutrient solution into the dish;

[0037] Among them, the gauze can provide good support and air permeability for the seeds, ensuring that the seeds can evenly absorb the nutrient solution during the hydroponic process. The nutrient solution provides the necessary nutrients for the growth of hydroponic seedlings and promotes the healthy growth of hydroponic seedlings.

[0038] S6. Spread the germinated seeds evenly in the hydroponic tray, keeping the surface of the seeds flat and avoiding overcrowding;

[0039] Among them, evenly spreading seeds can ensure that each seed can obtain sufficient light, nutrition and growth space, avoiding poor growth caused by overcrowding of seeds.

[0040] S7. Control the growth environment of seeds;

[0041] Among them, controlling the growth environment of seeds is beneficial to improving the yield and quality of hydroponic seedlings.

[0042] S8. Harvest.

[0043] Furthermore, in step S2, the concentration of the hydrogen peroxide solution is 0.2%, the soaking time is 12-15 minutes, and the number of cleaning times is 3-5 times.

[0044] Among them, a 0.2% hydrogen peroxide solution concentration can effectively kill germs on the surface of seeds without causing damage to the seeds. Soaking for 12-15 minutes can ensure the disinfection effect, and washing 3-5 times can completely remove residual disinfectants and avoid negative effects on seed germination.

[0045] Furthermore, in step S3, the temperature of the seeds soaked in water is 20-25°C, and the soaking time is 8 hours.

[0046] Among them, the temperature range of 20-25℃ is the best temperature for seed germination, which can promote the physiological activities inside the seeds and accelerate the germination process of the seeds. Soaking for 8 hours can ensure that the seeds fully absorb water and activate the germination mechanism of the seeds.

[0047] Furthermore, in step S5, the formula of the nutrient solution is a mixture of 0.05% aspirin and 0.05% white sugar.

[0048] Among them, aspirin can promote plant growth and stress resistance, while white sugar provides the necessary energy source for hydroponic seedlings, ensuring that the hydroponic seedlings can obtain sufficient nutrients during the growth process.

[0049] Further, in step S6, the seed density is 3300 g / m 2 .

[0050] Among them, appropriate seed density can ensure that each seed can obtain sufficient growth resources, avoid poor competitive growth caused by excessive density, and improve the overall quality and yield of hydroponic seedlings.

[0051] Furthermore, in step S7, the humidity of the initial seed growth environment is 70-80%, the light intensity is controlled at 4000 l ux, the light time in the seed germination stage is controlled at 8 hours a day, and the rest of the time is in a dark state, and in the seed germination stage, the light time is controlled at 16 hours a day and the rest of the time is in a dark state.

[0052] Among them, controlling the humidity at 70-80% can provide a suitable moisture environment for hydroponic seedlings and avoid poor growth caused by too high or too low humidity. Controlling the light intensity at 4000l ux can provide sufficient light for hydroponic seedlings and promote photosynthesis. Controlling the light time can simulate natural light conditions and promote the healthy growth of hydroponic seedlings.

[0053] It should be noted that during the seed germination stage, the hydroponic tray needs to be rinsed with running water once every morning and evening to prevent mold growth.

[0054] Furthermore, in step S8, the hydroponic seedlings are harvested when they grow to 15 cm, taken out of the hydroponic container, rinsed with clean water, drained, and then packaged for sale.

[0055] Among them, harvesting the hydroponic seedlings when they grow to about 15 cm in height can ensure the quality and yield of the hydroponic seedlings. After harvesting, rinsing with clean water and draining the water can remove impurities and residual nutrient solution on the surface of the hydroponic seedlings, ensuring the cleanliness and safety of the hydroponic seedlings.
