Cucumbers are one of the earliest vegetables to appear in the spring and most often grow in open ground. However, fruits grown in greenhouse conditions can be harvested almost all year round. This requires a greenhouse that will be warm without drafts, properly selected seeds, as well as compliance with agrotechnical measures.
Varieties of cucumbers
All varieties of cucumbers can be divided into several classes:
By collection date:
- winter-spring harvest;
- spring-summer ripening;
- summer-autumn variety.
According to the speed of ripening, cucumbers are:
- early;
- mid-season;
- late ripening.
By pollination method:
- insects;
- self-pollinating;
- parthenocarpic.
By purpose:
- for canning;
- for salads;
- for universal use.
Not all varieties are suitable for greenhouse cultivation of cucumbers. The most suitable are self-pollinating and parthenocarpic species.
It is necessary to take into account that the 1st variety (self-pollinating) cucumbers have seeds inside the fruit, and the 2nd variety does not have them at all. In addition, these varieties have good yields and are also resistant to diseases that are inherent in cucumbers grown in the ground.
Salad varieties of cucumbers are grown smooth, With smooth skin without thorns or with small thorns, which are always white. Their skin is quite thick and dense, which allows them to be transported over considerable distances without damaging the fruit.
Cucumbers intended for canning have thin skin. This feature allows the marinade to penetrate evenly during salting. These cucumbers are grown in large sizes.
If the variety is universal, then it can be eaten raw in salads, and it is also suitable for canning. Varieties grown for salads are not recommended for canning. This can negatively affect the taste of the preserved food, as well as significantly reduce its shelf life. The purpose of the fruit is indicated by the manufacturer on the packet of seeds.
Another option to achieve a similar result is to plant cucumbers at regular intervals, when previous plantings produce the first flower.
Advantages of greenhouse cucumber varieties
Having a greenhouse equipped for growing cucumbers provides a number of advantages:
- large harvests;
- constancy of maturation;
- disease resistance;
- a large selection of varieties that can be subsequently used both fresh and pickled.
There are types of cucumbers that can produce up to 30 kg per 1 sq. meters.
In addition, the resulting fruits do not have a bitter taste, and when planted they have almost 100% germination. Most of them are self-pollinating varieties.
Features of Dutch varieties
These types of cucumbers have some features that must be taken into account when cultivating them. These include:
- sowing is carried out in late March in pots;
- subsequently, when planting, the row spacing is 2-4 cm;
- While the seeds are in pots, you need to prepare a mixture that includes peat, rotted manure, soil and coarse sand. The mixture itself can be placed in peat pots for seedlings;
- after the cucumber seeds sprout, they are carefully planted in the prepared mixture in pots;
- Then they wait until 3-4 leaves sprout and plant them in a permanent place in the greenhouse. In addition, it is necessary to take into account that cucumbers sprouted from Dutch seeds must be planted according to an exact scheme, compliance with which will ensure the proper high yield:
- Trenches are dug along the length of the entire greenhouse, the depth of which is 40 cm. Pots with grown plants will be planted in them.
- the distance between the trenches should be at least 80 cm. This will allow them to grow in the future without interfering with each other.
- At the bottom of the prepared hole, place manure in a layer of at least 5 cm. Then you can proceed directly to planting.
- The plants themselves must be planted in a square pattern
When the cucumbers begin to grow and grow, you need to remove the first tendrils and pinch the tops. After the plants continue to grow and produce the next series of tendrils, you can feed the cucumbers.
Some varieties of Dutch cucumbers
The secret of the frequency of planting Dutch cucumber seeds lies in their reliability, which ensures not only high yields, but also greatly simplifies the process of caring for plants.
Angelina F1
One of the representatives of the Dutch selection. The F1 marking indicates that this type of cucumber is self-pollinating. The length of the fruit can reach 14 cm. Cucumbers of this variety are suitable for salads and other dishes where they are used raw.
Its main characteristic is its ease of maintenance. They belong to early varieties.
Gunnar
Hybrid species of Dutch breeders. Cucumbers of this variety have good shelf life and, therefore, transportation characteristics. It is classified as a mid-late variety and, according to climatic conditions, is most suitable for planting in temperate latitudes.
It is of medium yield, but its taste is excellent due to the presence of large amounts of sugar and ascorbic acids. The length of the fruit reaches 13 cm.
Hector F1
Early ripe cucumbers. They are characterized by a dark green color of the peel with dense pulp. A distinctive feature is that the greens do not turn yellow and always retain their color. The size of the fruit and fairly thin peel allow them to be used for preservation.
This variety of cucumber is not tall; it grows as a bush, but with a large number of fruits. This growth greatly facilitates plant care and harvesting.
Bettina F1
Small cucumbers, which are classified as gherkins. This is an early ripening variety that can grow in low light levels in a greenhouse.
This plant is characterized by the fact that the main amount of the harvest is concentrated on the central stem, so it does not need to be formed. Cucumbers have a delicate taste and are not bitter.
Herman F1
Refers to early ripening varieties of Dutch selection. They are distinguished by high productivity throughout the entire fruiting period.
They are characterized by dark green fruits with tubercles. They are universal and can be used for salads and canning without losing their taste. This is a tall variety of cucumbers.
The yield of cucumbers depends on the choice of seeds, correct adherence to planting rules, as well as timely application of the necessary fertilizers, and maintaining the microclimate in the greenhouse.
The final choice of cucumber variety for growing in a greenhouse depends on taste preferences, methods of using them, and also based on personal experience in growing these fruits.
