1st Stage: Seed preparation. Pre-sowing preparation is of great importance for accelerating seed germination and obtaining production at an earlier date. They must be purebred with good germination and vigor. The etchant allows you to destroy pathogens and protect young shoots from them. This method stimulates the physiological processes that occur during seed germination and growth of a young plant. A liquid solution "BIOTECH" with a growth biostimulator is used at a concentration of 1 liter of fertilizer per 10 liters of water. This increases the resistance of plants to diseases and unfavorable conditions, satisfies their need for micro and macro elements, especially manganese in an easily assimilated form, which will help to germinate faster after planting. The seeds are immersed in a solution of the preparation (+ 35 ° C ... + 45 ° C) for 15-20 hours, followed by rinsing with water. At the end of the processing, they are scattered in a thin layer, and, stirring occasionally, they are dried. The treated seeds are sown immediately. Sowing and planting are carried out in early spring - soil temperature in a 10 cm layer is + 10 ° C ... + 12 ° C.
2nd Stage: Preparing the soil. Tilling the soil for onions begins in the fall, while the site is deeply dug or plowed into the fall. In early spring, they harrow, limiting the evaporation of water. Subsequent processing is carried out taking into account the characteristics of the soil. Planting of seedlings and large onions is carried out on a plowed or dug area in a prepared bed. For introduction into the soil before planting, a universal substrate "BIOTECH" is used "vermicompost", a product rich in micro and macroelements that retains moisture, improves the structure of the soil and strengthens the root system of the plant, in proportions of 10 liters of substrate per m². Seeds or sets are planted in prepared and carefully loosened beds. Onions are planted in rows with a row spacing of about 30-40 cm and a distance in a row from 6 to 10 cm and a planting depth of about 4 cm. Small-breeding varieties are planted denser. Shoots appear on the 10-14th day. All stages of dressing are carried out in dry, calm weather, in the evening. You need to pour it at the root, trying not to get on the greens. 24 hours after feeding, it is advisable to spray the plant with clean water so that no fertilizer residues remain on it.
3rd Stage: Watering and first feeding. Primary feeding is carried out 14 days after planting the plant. Liquid fertilizer "BIOTECH" at the rate of 20-25 g per 10 liters of warm water. Apply the solution under the root for 10 running meters. This will provide additional impetus for growth. Water the onion once a week at a rate of up to 12 liters of water per 1 m², or use automatic drip irrigation. Irrigation water +18 ° C to avoid powdery mildew contamination. After that, the plantings are necessarily spud and the aisles are loosened to provide access to the roots of oxygen. Onion care in June also offers protection from insects and disease. Once a week in wet weather, and every 2 weeks in dry weather, they are treated with fungicides. In this case, the fertilizer can be used in conjunction with fungicides. Fertilizer will enhance their action, being a good adhesive. If there is no prescription in the fungicide regulation.
4th Stage: Watering and second feeding. On the 20th day after the end of the first feeding, secondary fertilization is carried out. 10 g of BIOTECH liquid fertilizer per 10 liters of warm water. This is the optimal feeding of onions at the stage of active head formation. At high temperatures and prolonged heat, watering is carried out twice a week, at the rate of up to 6 liters of water per 1 m², in the morning or in the evening under the leaves. 5th Stage: Watering and third feeding: The third, final feeding - when the onion head has reached a diameter of 4-5 cm. 10 g of liquid BIOTECH fertilizer per 10 liters of warm water. 2 weeks before harvest, watering is stopped. We offer modern technology for growing vegetables and berries in greenhouses all year round. By replacing a 20 cm soil layer with a universal substrate "BIOTECH" "vermicompost" or by sprinkling a layer of the same thickness on top, thereby warming the soil. The effect is achieved due to the heat-insulating properties of the substrate, which will maintain the optimal temperature for the roots of plants and nourish the heated soil with all the necessary micro and macro elements. It is also imperative to maintain a constant air temperature of + 22 ° C ... + 24 ° C. In this way, vegetables and berries can be grown in winter.
