Growing seedlings

Advantages of the seedling method of growing in are basically that to the fact that in the initial period of life plants develop under optimal conditions of illumination, humidification, temperature regime and nutrition. As a result, plants accelerate their development and produce products earlier on average for 2-3 weeks. In this case, the better the quality of seedlings, the greater the advantage in growth is obtained by the plant. The seedling method also makes it possible to grow thermophilic plants in the northern regions, which differ in a long vegetation period and do not have time to form productive organs before the onset of cold weather.

Soil substrate requirements

The soil substrate must have a light mechanical structure so that when the seedlings are removed for planting on a permanent place on the roots, there is a clod of soil.

Depending on the type of substrate, sod, earth, peat, sand and compost can be included in different proportions.

To reduce the acidity of substrate components such as peat and turf, lime or chalk is added at a rate of 100 grams per bucket of substrate.

Before the substrate is formed, each of its components must be passed through a wire mesh screen with a size of 2x2 or 3 x 3 cm to give the substrate a more uniform, loose structure.

In the soil substrate, it is necessary to add the basic mineral fertilizers, depending on what culture is planned to grow. The main fertilizers are ammonium nitrate, superphosphate, potassium chloride.

The seedlings and pots should not be filled with the substrate to the very top so that water does not drain from them when watering.

Seedlings are grown in two ways - bezgorshechnym and pots. When is a non-comedose method, the seeds are sown in seedlings filled with soil substrate, followed by picking seedlings.

In a seedless way, vegetable seedlings are grown, which tolerates transplantation well-cabbage of medium and late varieties, tomato, rutabaga, beet, onion and leek, celery.

Pottery grows seedlings of crops that do not tolerate damage to the root system and require a large area of ​​nutrition. This method avoids the subsequent picking, and seedlings fall on a permanent place of growth strong, with a well-developed root system. In addition, with the potter's method of growing seedlings, the plant survival rate increases considerably when planting on a bed. According to some reports, growing seedlings in pots without picking speeds up harvesting by an average of 15-20 days compared to a non-mildew method. This is due to the fact that plants of seedlings are better provided with nutrients and grow stronger.

Data on the dates given in the table can be adjusted with a shift of several days depending on actual soil-climatic and weather conditions.
