Many gardeners formed the opinion that watering tomatoes in the greenhouse should be daily and plentiful.Unfortunately, this is absolutely the wrong approach.A distinctive feature of this type of crop is a deep-seated root system.In addition to water, and they require the presence of loose soil, the roots can breathe.Therefore, planting tomatoes in the greenhouse, watering should be organized somewhat differently.
microclimate of greenhouses in central Russia
in central Russia humidity from spring to fall from 60 to 85%.In particularly hot years, what turned out to be 2010, this option in August, did not rise above 40%.But it is rather an exception to the rule.Usually hot days interspersed by rains, when the humidity is over 90%.The protected ground temperature above ambient in the cloudy days at 10 ... 13 ° C, and in the sun for more than 20 ... 28 ° C.Therefore, the excess water under high humidity adversely affect the tomatoes in a greenhouse.Watering should be recessed to the roots.To avoid waterlogged, arrange ventilation.It does not always produce the desired result, so that the growth begins rot fungi.Blackleg - a frequent visitor in the humid greenhouses where tomatoes are grown.Since mid-July, when the probability of precipitation increases, developing late blight - a clear sign that the condensate from the inner surface of the transparent protections on the leaves turned and began its destructive effect.
How much water the tomatoes in the greenhouse, the recommendations from abroad
Foreign authors advertise a full irrigation system.Of these clips show how the jet of water, scatter the shower head, washes tomatoes from top to bottom.This narration cheerful voice broadcasts on high yields and quality.One would believe them.Just confused by the fact that the taste of imported tomatoes is far from usual.To arrange such glaze, foreign growers use as chemical plant protection that completely remove the feeling of the presence of real fruit.The pictures from abroad, you can see the beautiful tomatoes in the greenhouse, watering them spoiled.But there is another truth that does not like to show advertisers and manufacturers of irrigation equipment.Only a small part of the harvest of the first pickup looks so beautiful, disease later nullify all the efforts on growing tomatoes.
How indeed should be watered the tomatoes
have already mentioned that the root system of the Solanaceae crops located below ground level at 20-25 cm. Pretty deep form the roots of tomatoes in the greenhouse.Watering should therefore be referred to a lower part of the roots.Some critics might argue that, for example, in Israel the water continually drips near the root, and no plant diseases do not show.Of course, there is allowed.But for one reason only - tomatoes are grown in the southern countries in the open ground in the absence of atmospheric moisture, relative humidity rarely rises beyond 40%.In the same morning dew Israel occur only during the winter, and the temperature in the coldest days rarely drop below 8 ° C.In 2012, there were a few cold days, when the temperature is close to zero.Several people froze to death, and in residential buildings (heating is not there) it was pretty uncomfortable.One conclusion: in our conditions, growing tomatoes in the greenhouse, watering should initiate deep into the soil to reduce the humidity.
How to prepare the soil in the greenhouse
in buildings protected ground before laying the new soil to a depth of 20-25 cm should put the battery wet.Moss, a gel used sponges and other items concentrating moisture it will hold at a given level.Located above the soil or substrate.The battery is necessary to bring water tube feeders through which water, bypassing the upper soil layer, penetrate down.Now you can organize drip tomatoes in the greenhouse.When growing tomatoes, there is also such a thing as a "dry irrigation".In fact it is a loosening of the soil near the roots of the upper layer to saturate the air.
Provided follow our guidelines specified gardeners can expect to receive real high yield with excellent quality of tomato fruits.
