Why cucumbers are not tied in the greenhouse

Many gardeners are wondering why cucumbers are not tied in the greenhouse. It is important to correctly and timely determine what disrupts the normal development of plants and eliminate the problem.

Cucumbers in the greenhouse

Rules for planting in a greenhouse

Today is a blessing There are a large number of cucumber varieties for breeders to work in. Cucumbers can be large and small, early or late, lettuce and pickles, tuberous and smooth-bred, earlier and later.

Harvested crops in open ground possible at a later date. Greenhouses are great for getting early vegetables. But for the correct and timely fruit setting, certain rules must be observed. Varieties for greenhouses are divided into the following groups:

• winter-spring;
• spring-summer;
• summer-autumn.

Each of these groups, in turn, is divided into precocious, mid-ripening and late-ripening. They can be bee pollinated and parthenocarpic.Parthenocarpic ones were created for growing in closed greenhouse conditions, where there is much less light and solar heat. And, of course, there is no access for pollination by insects.

Causes of a poor ovary

When the cucumbers in the home greenhouse are not tied, the symptom may be an abundance of empty flowers. It seems that the culture is quite healthy, does not lag behind in development, blooms and does not get sick. But the long-awaited fruits do not appear. There are several factors affecting fruiting:

• choice of variety and subgroup;
• pollination;
• temperature in the greenhouse;
• lighting;
• watering mode;
• top dressing;
• seedling quality.

You need to thoroughly understand all the subtleties before planting seeds in greenhouse or seedlings.

Influence of the variety

Early varieties are characterized by excellent taste. This is usually a salad type. But a big harvest is rare for them. They are more prone to disease. Depending on the size of the room, one or another variety should be considered. One needs large sizes due to constant growth. Other varieties require heating more than usual. There are varieties that are pollinated only by artificial methods.

It is better to choose from those varieties or Dutch hybrids that are bred specifically for a particular region and climatic conditions. The best variety can lose in the final crop, because it has different requirements for soil, climate, pests and diseases.

For cultivation, it is better to use fertile soil saturated with humus. You can replace it with special store mixes.

Pollination its methods

Bring insects to the greenhouse

The most common cause of poor ovary is poor pollination of the flower or its absence. In a closed greenhouse space this may not happen.

1. You need to open the side wings of the greenhouse and draw insects inside. This can be done on warm, sunny days. When weather conditions do not threaten plants.
2. You can attract the necessary insects by planting hawthorn, oregano, thyme, valerian, etc. near the beds. If it is not possible to plant such plants near vegetables, you can plant them in separate pots and simply expose them next to the beds during the flowering period of cucumbers. Honey plants with their aroma will attract the attention of bees and bumblebees. Pollination will occur and the fruits will be tied.
3. There is an option to buy a family of bees. One or more, depending on the size of the greenhouse. Such families are sold directly in special boxes with feed. These boxes just need to be opened and put in the greenhouse. Periodically adding only water for bees. The family adapts after some time in this place, begins to fly out and pollinate the plants.
4. There is a method of manual pollination.You just need to take a soft brush and touch each flower in the center. Thus, pollen will transfer from one flower to another, i.e. artificial pollination.

Influence of the temperature regime

The temperature regime plays an important role in this matter. A sharp fluctuation in air temperature is detrimental

1. If a cucumber crop was planted early or there was a sharp cooling outside, artificial heating should be used. Especially you need to pay attention to the temperature at night.
2. To reduce the risk of freezing plants, it is better to plant them immediately on warm beds – sawdust covered with soil is pre-sprinkled under the plants. Natural heat is generated from the decaying reaction and warms the earth.
3. A little garden trick: a “night warmer” for cucumbers will help to get an excellent harvest even in the rainy summer.
4. If ordinary beds should be covered at night with film or mulch. You can even leave the mulch for the entire growing season.
5. In the afternoon, it is necessary to ventilate the room, creating air movement. This procedure will help to avoid overheating, create comfortable conditions for the sprouts, help the aroma of odorous herbs to attract insects inside the greenhouse.

It must be remembered that cucumbers do not tolerate overheating. The temperature should not be higher than 29 – 30 ° C. Especially during the flowering period.Under other conditions, the pollen will become sterile and the ovary will not be able to form.

Influence of the irrigation and lighting regime

Provide the plants with complete care

Watering and lighting are many important factors for a good harvest. Good growth requires high humidity. About 70-90%.

1. The soil should not dry out. Good watering is needed. But we must not allow puddles and complete soil soaking, i.e. slush. Soil moisture should be between 50-60%. A good way of watering is sprinkling. You can use drip irrigation, using tubes with holes at a certain distance from each other. If the room is small, you can use bottles without plugs stuck in the ground between plantings for uniform watering.
2. You need to pay attention to the temperature of the water for irrigation. If watering is carried out with cold water, this will be an additional stress for plants. May lead to a reduction in the development of female flowers or to their complete absence. Male flowers do not bear fruit.
3. It is better to heat the water. You can water in the evening. Pre-fill the water in the tank for irrigation, and it is heated in a natural way during daylight hours in the room.

The watering regime during the growing season can be as follows:

• before flowering;
• during the period of fruit development;
• as the soil dries up;
• during the formation of the ovary.

The lack of lighting adversely affects the formation of the ovaries. Before landing, you need to carefully consider the location of the lighting lamps. They will be needed with a lack of sunlight. Buildings close to the greenhouse or tall trees can also interfere, creating a shadow.

Effect of feeding

Good and competent feeding of cucumber crops has a big impact on the quality and quantity of the final crop and can solve the problem of lack of ovaries forever.

Mineral fertilizers should be applied to the soil regularly and preferably in small doses. It is quite possible to combine this with watering.

Additionally, plants should be sprayed with stimulators of fruit formation. For this, you can use good preparations of Bud, Ovary. It is better to use it once a week from the moment the cucumbers begin to bloom.

Influence of the quality of seedlings

If planting is done in the seedling method, you should pay attention to the quality of the seedlings. Weakness of plants can cause lack of ovaries. Cucumber culture forms at the same time male and female flowers

If there are a lot of empty flowers, the sowing was carried out with fresh seeds.It is optimal to use seeds that have been in storage for 2 to 4 years. Perhaps the seeds did not warm up before planting. Thus, the agrotechnical rules for growing seedlings were violated.

Why cucumbers do not grow

Sometimes, even with normal care, vegetables do not grow. Cucumber is a heat-loving vegetable, it is cold in the beds in temperate or unstable climates.

You can observe that the plants begin to languish, stop growing or rot. This can happen after tying the cucumbers on the stem. This is observed even in self-fertile hybrids. It is the decrease in night temperature that prevents the growth of the ovary. In rainy weather, downy mildew also appears. This disease is also called perniporosis.

To prevent this, the land under the plantings should be without excess moisture, well ventilated. Affected leaves should be removed and destroyed immediately. You can’t put them in compost. To prevent the disease, while the plants are small and the ovaries are not large, you need to spray them.

Conclusion

For a good harvest, many rules should be followed. If cucumbers are not tied in the greenhouse, you should analyze everything and draw conclusions. Adjustment in the cultivation and care will allow us to rejoice at the results.
