Why tomatoes bloomed profusely, and has grown little fruit.

Summer vacationers often notice the appearance of a multitude of little yellow flowers in tomatoes. It can be formed of 7-8 flowers, and in some varieties and 10-12 inflorescences, however, there is much less of the ovaries. As a result, the brush can be detected only 2-3 fruit or even all the flowers are starting to crumble. The reasons for this, perhaps, a lot of, well, first of all it is connected with the violation of agro-technical standards and improper care. Well, let's look and see, because of what our tomato plants bloom profusely, but the fruit set is not happening.
Tomatoes - are plants that pollinate themselves on their own, without the need for outside intervention.

Why does the flower can not be fertilized? This is indicated by several factors:

Pollen from the strong humidity curled into a ball and crumbling;

Pollen sterile, or not yet fully matured;

If insufficient nutrients or improper maintenance may remove all plant buds (poor lighting, peresushka soil wrong temperature).

To flower pollination happening without possible difficulties, should ensure that all the necessary conditions for it. To do this, you need to pay attention to moisture, food, air temperature, that is, those indicators that are essential for the effective formation of the ovary.
To ovaries was much longer, the following conditions must be met:
1. When the plants begin to bloom humidity should be 40-70%. This should be given special attention. In rainy weather or at high levels of moisture greenhouse, unopened flowers are starting to fly around, and pollen to stick to them as a result of the flowers do not normally pollinated.
In the rainy summer flower bud is much worse, and to change this factor can not unfortunately. And here in the greenhouse, the situation is a little different from all the protected deposits, however, is likely to overheat plants. In this case, be sure to ventilate the greenhouse and use other techniques to protect plants from overheating. 2. The air temperature must be +14... + 29 degrees. If it is below 14 degrees, you can see how the ovaries will be less. If the temperature drops to 10 degrees, then they would not be at all, because in such cases the pollen is not formed at all. At a temperature of 29 degrees tomato ovary also formed poorly, and when raised to 36 degrees, and it becomes completely sterile. Therefore, the ideal temperature readings will be from +14 to +29 degrees.
3. Particular attention should be paid to proper watering during flowering and ovaries. Though tomatoes and are drought-resistant plants, however, abundant irrigation is still needed. With insufficient amount of moisture flowers and ovaries begin to peel off, and at regular and low water plant does cease to flower, stem tops inclined and foliage bend. More carefully to relate to irrigation in greenhouses, since there are no any any precipitation.
4. Small amounts of nutrients lead to tying only the first flowers, and all the rest will fall down, because the necessary elements will not come to them. If you had seen that out of 5-9 available flowers only grow during the first 2-3 and the rest just fall off, it is possible to deal in food shortages. In this case, it is important to use more fertilizers with phosphorus and potassium, but overfeeding nitrogen plants are not worth it, because it can trigger their greasing. The special effect is achieved foliar feeding boric acid is used for this, 8 g of boric acid to be diluted with warm water to 10 liters. Cooked dressing need to go on a tomato leaf. This procedure should be done 4 times every 2 weeks. At flowering and fruit formation in plants is boron and is an essential trace element, which is so important to use. 5. Improper pollination in the greenhouse. A small amount of the ovaries may be an indication that in the greenhouses there is no draft and insect pollinators, which would be able to move pollen from one flower to another. Therefore recommended in the morning to shake open flowers to each other, to pollination occurred. If all of the above rules, you can get a lot more of the ovary, and on the hands will be a lot of fruit. In particular, these requirements will be relevant for the greenhouse, because it is here that it is possible to control all the main factors that have the greatest effect on the formation of the fruit.
