In order to obtain a good harvest of pepper, temperature is important throughout the growing period. As you know, at air temperatures above 30-32 degrees, pepper flowers are not pollinated and fall off. But the fruits of pepper are not set even at average daytime temperatures below 15-16 ° C.
Therefore, in sunny hot weather, the greenhouse must be ventilated, while avoiding drafts. When the air temperature rises above 30-32 ° C, the plants must be protected from direct sunlight. To do this, most often the glass roof is sprayed with a solution of chalk or shaded with light wooden shields. And in film greenhouses, the film is lifted up from the sides, rolling it onto the bobbins.
Pepper is extremely light-loving. Therefore, when planting thickens, its flowers are not pollinated and fall off, while the yield is sharply reduced. It reacts positively to additional pollination by shaking the trellis with plants.
Pepper is very picky about soil moisture, does not tolerate even short-term drying out. Plants especially need moisture within 8-10 days after planting, during the flowering period of the first and second brush, before loosening the soil, after applying dry mineral fertilizers to the soil. Lack of moisture in the soil can lead to lignification of the stems, the fall of the ovary and leaves, as in eggplants. Pepper also reacts negatively to excess moisture in the soil.
The amount of water for one irrigation depends not only on the weather and soil, but also on the planting scheme and variety. It is desirable that the water is rainwater. In its absence, it is necessary to water only with water that has settled in the tank, heated to a temperature of at least 24-26 ° C. Therefore, water storage tanks should be installed in a well-lit place (best of all, in a greenhouse), painting them black ...
