Growing cabbage seedlings in a greenhouse
Seedlings of cabbage in a greenhouse are easy to grow, you need to carefully prepare the soil, seeds and start planting. If you follow all the rules of cultivation, you can get a delicious vegetable harvest.
Growing cabbage seedlings in a greenhouse
Soil preparation
The resistance of seedlings to pests and diseases depends on how the soil is prepared for planting in the fall. Sod land is mixed with humus in equal parts, and 100 g of ash is added for every 10 kg of soil obtained. In some cases, the sod is changed to peat.
It is recommended to use a soil that is breathable and fertile.
Seed preparation
Growing cabbage seedlings in a polycarbonate greenhouse, as in a conventional greenhouse, involves the use of prepared and treated seeds. Before planting, they must be heated - add seeds to water up to 50 ° C and hold for 20 minutes, then send them into cold water for 5 minutes. Before sowing, this is done to combat fungal diseases.
Sowing and growing rules
It is possible to grow cabbage seedlings in a greenhouse of different ripening periods, while the time frame for planting seed should be understood:
- early maturing - it is recommended to sow from March to mid-April;
- mid-season - during April;
- late maturing - should be planted before May.
Growing seedlings
Seedlings need to dive
In the greenhouse, cabbage is grown in seedlings at a distance of 15-20 cm, with depressions up to 3-5 cm. Furrows for planting are watered, seeds are laid out in them and covered with soil. The planted vegetable varieties must be given designations so that there is no confusion.
The sprouts that appear should be weeded out. The seedling occupies an area of 2 × 2 cm.After 2 weeks, a pick is made according to the 3 * 3 scheme, after another 2 weeks the seedlings are moved into pots, glasses with a size of 5 * 5 cm.
Growing cabbage seedlings in a polycarbonate greenhouse is possible under the following conditions:
- auxiliary lighting (electroluminescent lamp);
- measured watering (absence of droughts and moisture supersaturation);
- the most favorable temperature for strengthening seedlings (15-17 ° C during the day, 8-10 ° C at night).
Seedling care
It is possible to grow cabbage seedlings in an unheated greenhouse, while auxiliary heaters are used to maintain the required temperature.
For growing seedlings in the greenhouse, fertilizers are used: the first potash fertilization is carried out a week after the pick; the second (2 times stronger than the first) - in two weeks; the third - a couple of days before transplanting from the greenhouse.
After the first full-fledged leaf that appears, treatment from pests should be carried out, after the fourth leaf, soil, peat, and medium-sized sawdust are added to the plants. After weeding, the grown seedlings are watered. The development of plants is positively influenced by their treatment with drugs that stimulate growth.
Hardening of plants
For growing seedlings in a greenhouse, hardening is characteristic, which allows the plants after planting to remain resistant and give a super harvest. Initially, the temperature in the greenhouse remains at least 15 ° C throughout the day. In warm weather, the plants are opened for 15 minutes, with each week increasing this time by another 10 minutes. At night, the temperature remains at least 8 ° C, the window remains open for ventilation, during the day the plants are completely opened for several hours.
To speed up the process of adaptation of seedlings to open land conditions, it must be fed with natural potash fertilizer - ash a day before planting. The seedlings will be hardened and ready to be transplanted outdoors.
Conclusion
It is possible to grow cabbage seedlings in an unheated greenhouse or from polycarbonate only if special rules are followed. It is so important to take the time to select high-quality seed and sowing rules. Watering and stabbing will also work and help the sprouts to cope with uncomfortable conditions.
