Strawberry is a delicacy from which adults and children come to delight. Today it is cultivated not only for eating. The sale of berries brings revenue, but for this they need to be cultivated in large quantities. Growing strawberries on Dutch technology is one of the most common methods. Its main advantage lies in the possibility of year-round harvesting.
Performance - above all
The Netherlands exports more strawberries than other countries in the world. Despite the fact that the country occupies a small territory, breeders extract the maximum result with a minimum area.
The Dutch planting of strawberries is based on the creation of greenhouse conditions for the development of culture, as well as the use of modern technology achievements. The equipment is designed to monitor and maintain humidity, temperature, lighting. In artificial conditions, the life cycle of bushes is prolonged, which are protected from any climatic fluctuations.
Features of the
Technique At home growing berries on Dutch technology, it is worth considering some points:
- Bushes are planted in a closed ground. Preferably equipped with greenhouses.
- Seedlings are planted continuously. The longest period between disembarkations is about 40 days. The technique is called simple forcing. It consists in the fact that shrubs are only suitable for one-time harvesting. In their place are planted new ones.
- Planting material can be purchased in specialized companies. Despite the high cost, self-pollinating varieties are profitable, since they bring a good harvest. It is recommended to use seminal species for the Dutch seeding technique: Tristar, Sonata, Selva, Polka, Maria, Elsant, Darselect, Dark and Marmolada.
- Only under the condition of "artificial rest" is this technology of growing strawberries effective. Shrubs for planting practical gardeners harvested independently. They are planted at the end of summer, and in autumn they dig out and cool in special freezers.
Shrubs are suitable for planting in the ground, regardless of the season.
The advantages of the Dutch method
All those who grow strawberries on this technology, mark the merits of the method. They are as follows:
- seedlings are planted in various containers - pallets, boxes, pots or sacks;
- a large crop yield even on a minimal area, perhaps vertical placement of bushes;
- maximum natural light due to the transparent walls of the greenhouses;growing in pots growing in bags
- easy application of the technique at home, strawberries can be planted on the balcony, in the garage or on the windowsill;
- seedlings are not infected, because in the greenhouse sterile conditions, and the tanks are processed by special means;
- technique is beneficial if you are engaged in selling strawberries, because the harvest of berries ripens every 40-60 days;
- berries retain their natural taste, color and odor;
But most importantly, berries are distinguished by their naturalness, quality, ecological purity and bioavailability.
Arrangement of a place where culture will grow requires special attention. The correct greenhouse equipment for growing strawberries according to Dutch technology provides:
- Availability of special containers, where the bushes will grow. Depending on the size of the greenhouse, it is recommended to use plastic containers, flower pots or polyethylene bags with pockets. flower pots polyethylene bags with pockets plastic container
- Substrate manufacturing. The nutrient mixture is made from perlite mixed with peat. In some cases, the container is filled with mineral wool or coconut fiber, and nutrients come from watering.
- The right soil. When cultivating strawberries in a greenhouse in Dutch technology, garden soil is unacceptable. Pre-cleaned from seeds of weeds, the soil is mixed with fine sand and compost.
- Effective watering system. Water jets, directed from above, reduce the yield of bushes. During periods of fruiting or flowering, a drip irrigation system is needed. For commercial purposes it is worth buying special equipment. If the berry is grown on a windowsill or loggia, it is possible to build watering from ordinary droppers.
- Lighting. Transparent walls of the greenhouse let in sunlight. It is enough in the summer, but for the rest of the year it's worth taking care of artificial light sources.
Do not forget about climate control. The equipment maintains optimal parameters, which are not affected by heat and cold.
How to harvest seedlings?
Dutch technology involves planting only elite self-pollinating shrubs. When growing berries for commercial purposes, the constant purchase of seedlings is unprofitable. Breeders and gardeners use the pasture of their own material or freeze seedlings with an open root system that is stored at -2-0 ° C and is suitable for 9 months. Defrosted free on the day before planting.
Before embarkation, bushes are sorted according to the following standards:
- A - root system with diameter from 12 to 15 mm, presence of 2 peduncles;
- A + - with a diameter of 15 to 20 mm, the presence of 3-4 peduncles;
- A + extra - with a diameter of more than 20 mm, the presence of more than 4 peduncles.
One class A bush can collect 150 g of berries, from a class A + bush 150-200 g of yield is produced, a bush of class A + extra gives about 400 g of strawberry.
Strawberries on Dutch technology are planted according to the following scheme:
- Preparation of soil for disembarkation. The soil is fertilized in the autumn period.20 kg of lime, 5-6 buckets of compost or manure, 3 kg of potassium chloride and 5 kg of superphosphate are poured into one hundred parts. The earth becomes suitable for planting in the spring. 5 kg of superphosphate 3 kg of potassium chloride
5-6 buckets of compost or manure 20 kg of lime
- Containers for planting shrubs also require fertilized soil. The container is filled with a non-toxic substrate - peat, perlite, mineral wool, coconut fiber. The soil must be mixed with 3 parts of fine sand, 1 part of compost and 1 part of manure. Before fertilization, the soil is cleared of weeds.
- Planting seedling is performed in the spring on a chessboard layout of 25 × 30 cm. The width of the beds should be 80-100 cm. If the distance is reduced, the strawberry will grow densely and the berries will be small. It is advisable to form crests about 1 meter high.
- Horizontal method of placing bushes provides for their planting in boxes or flower pots. They are placed on special shelves in one or several tiers.
- The vertical shoots are planted in bags with holes at the sides. Optimal for the Dutch cultivation are packs of 200-250 cm in height and 16-18 cm in diameter.
- In the first year of cultivation of seedlings from uterine plants, shoots and peduncles are cut off. A year later, about 20-30 antennas are formed, which are rooted.
- Digging out the sockets is necessary in the middle of October or a little earlier. The bushes are cleaned of soil debris. If necessary, the root system is gently rinsed under running water, but not cut.
- Seedling canned in the freezer. The bunches are made up of 50-100 shoots, packed in polyethylene bags. Storage temperature from 0 to -2 0C.So plants do not develop and do not freeze.
Defrosting seedlings of frego is necessary at room temperature.
Creating conditions for growth
Strawberries on Dutch technology will bear fruit only under certain conditions. To achieve high crop yields, you can properly organize:
- Watering System. Bushes watered often, but not abundantly. The best option - drip irrigation.
- Access to fresh air. The room is ventilated periodically in the summer. In winter and autumn conditions, ventilation is organized.
- Pollination of plants. It is better to stop on self-pollinated varieties. If this is not possible, the procedure is carried out using the drawing brush. Pollen is transferred from one bush to another.
- Uniform material disembarkation. Plant shoots better in small batches.
- Maintain normal humidity. This indicator should be equal to 70-80%.It is achieved by using spraying.
- Normalization of photosynthesis. Plants need carbon dioxide. Increase its content in the greenhouse can be lit by gas burners or candles.
- Duration of daylight hours. Actually, artificial lighting or special phyto-lamps. They extend the light-days by 15 hours. Thanks to this, harvesting begins after the first month of planting.
