1st Stage: Treatment of seeds. Method for pre-sowing seed preparation. Agricultural technology of white cabbage involves high-quality preparation of seeds for sowing. The timing of sowing seeds should be planned depending on the time of planting seedlings to a permanent place (50 days before the desired planting in the ground). We recommend sowing cabbage seeds for growing seedlings in greenhouses. In them, the seedlings come out hardened and ready for planting in open ground. To get high-quality seedlings, the seeds must be pre-prepared before planting. The solution is prepared at the rate of 1 liter of liquid BIOTECH fertilizer per 10 liters of water heated to +50 ºC for 20 minutes. for better absorption of micro and macro elements into seeds, which will affect seedlings and healthy, strong seedlings. Sowing seeds is carried out in the soil warmed up to + 20 ºC; before sowing, the soil is watered abundantly. Seeds are planted to a depth of 2-3 cm. Seedlings can be grown in cassettes, or by simply sowing into the soil of a greenhouse (the so-called torn seedlings). The size of the heads depends on the fit. It is important to plant the plants in holes down to the first true leaf. After sowing, the cassettes should be placed in a chamber with a temperature of about +23 ºC… + 25 ºC and a humidity of 98% to provoke seed germination and ensure uniform emergence. The seeds are sown directly into the prepared soil. From above, the sowing is covered with a nutrient mixture and watering is carried out. During the day, under the influence of sunlight, cabbage will develop well.
2nd Stage: Preparing the soil. Cabbage - can be grown both outdoors and in a greenhouse. Ideally, the soil for cabbage seedlings should be prepared in the fall, or before sowing. For planting outdoors, you need to choose sunny locations. Seedlings by the time of planting in open ground (about 25 - 35 days after germination) should have 4 - 5 true leaves and a height of about 15 cm. Somewhere 12-15 days before planting seedlings in the ground, it is necessary to start the hardening procedure. The transplant should be done in the evening. Well-seasoned seedlings withstand short-term freezing of -3 ºC… -5 ºC, and formed heads up to -5 ºC… -8 ºC. Planting dates depend on the variety. In greenhouse cultivation conditions. The greenhouse soil must be fertilized and compacted with high quality. In the future, the soil is subjected to subsequent loosening and watering. For the formation of the crop, cabbage spends a large number of nutrients. To obtain high-quality seedlings, you should use ready-made peat substrates, pH-balanced, which contain a complex of micro- and macroelements. We recommend the universal substrate "BIOTECH" "vermicompost", which improves soil fertility, compensates for the lack of organic matter, improves water, thermal and air conditions in the soil, and enhances soil microbiological processes. Application rate: 5 l of fertilizer per m². The first feeding is carried out a week later, when the plant takes root in the greenhouse. Seedlings are watered with a warm solution of + 18ºC… + 20ºC, in proportions of 10 g of fertilizer per 10 liters of water, because it is during the seedling period that young plants are in great need of a balanced set of nutrients, which must be supplied in the most easily accessible form. The purpose of feeding is to develop the root system, reduce stress due to plant transplantation and quickly establish seedlings. Planting seedlings involves irrigation every 2 days based on 10 liters of solution (10 g of fertilizer per 10 liters of water) for each m².
Stage 3: The second dressing is applied at the beginning of the formation of heads of cabbage, for the normal development of the root system, improving plant nutrition, restoring and activating microflora, improving the availability of nutrients. It is necessary to actively water the cabbage during the period of tying its head, soil moisture is at least 70%. Subsequently, they are systematically watered with a solution of this preparation (10 g of fertilizer per 10 liters of water) for each m².
4th Stage: Harvesting. The first harvest is obtained 40-50 days after transplanting. White cabbage can be harvested mechanically (using combines and conveyors) or manually. When choosing a collection method, you need to be careful not to damage the presentation. When collecting cabbage for storage, it is necessary to leave 2-3 integumentary leaves on the surface of the head and the beginning is about 3 cm long. It is very important to carefully and correctly enclose the heads in a container or block. 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.
