watering vegitables in greenhouse

Let’s speak about thegrowing vegetables in greenhouse and harvest dependence of environmental factors.

The watering regime of greenhouse growing

Most of the vegetables contain a large amount of water. The level of water element in the vegetables can be up to 95% and that’s why almost every vegetable need the resources of groundwater for the formation of the good harvest.

The vegetables are divided into main groups according to the ability to absorb and use the water:

  1. The first group includes cultures that absorb water from the ground very well and use it as well. As for example we can include in this group table beets.
  2. The second group includes plants that absorb water well but they use it economically. This group includes such vegetables as pepper, carrots, tomatoes and parsley.
  3. The third group includes plants that poorly absorb water from the soil and completely waste it. These are such crops as cucumber, eggplant, spinach and others.
  4. The fourth group includes economical plants. Such vegetables poorly absorb water but they save it very well.

Also we would like to note that vegetables are very demanding on moisture. On this basis we can divide the vegetables into 3 groups:

  • The group of very demanding plants. This group includes the following plants: salad, spinach, cabbage and others.
  • The group of average demanding plants. This group includes such vegetables as cucumber, eggplant, pepper, celery and others.
  • The group of low demanding plants. This group includes the following plants: watermelon, melon, pumpkin, corn.

With a lack of water, the fruits cannot grow. The flowers and ovaries fall during flowering. It is also does not bring benefit when there is excessive moisture present in the soil. In case when waterlogged roots get the very low level of the air the root system begins to rot. As the result of all above the fruits become watery and tasteless. Also you can observe the cracking of the fruits.

The high humidity of the environment leads to the situation when the plants are more affected by vegetable disease. The soil should be prepared before planting the vegetables. If the ground is waterlogged then it is necessary to drain it before planting manipulations. Such processes as mulching and snow retention take place when the soil is too dry. The water regime is very easy to adjust when the ground is closed. In this case it is necessary to take into consideration the following: the characteristics of the cultivated crop, the phase of its development as well as the intensity of sunlight.
