Many gardeners and vegetarians think about how much vegetables and vegetables should I plant? How often do watering? How and when to do vegetable irrigation?
There are a few points to take in this direction. These tips on irrigation of vegetables include the type of soil, climate, and growing varieties of vegetables.
In examining the type of soil, it should be noted that clayey soil or sand ?!
Sandy soil drops quickly, but clayey soil saves high water content and keeps the water longer.
It is better to combine soil with sand and clay. Soil replacement with compost is very suitable.
The use of mulch is also recommended to reduce evaporation and increase moisture content.
In irrigation of vegetables, one must pay attention to the root depth of the plant. Deeper roots, the longer the irrigation period can be considered, and the shorter the depth of the root, the faster irrigation should be done.
Vegetables require 1 inch of water per week. According to the soil type, if the sandy soil is twice a week, it is 0.5 inches and if the soil is clay, once a week, it takes about 1 inch of irrigation.
Dipping the soil irregularly irrigates better than regular shallow watering. Deep soaking causes root to grow well.
The best time to irrigate the vegetables is early in the morning when the air is still cool. Irrigation in the morning reduces the evaporation of the water and, as a result, more water is available to the root.
If for any reason you are not able to irrigate the vegetables in the morning, the best time to irrigate late afternoon.
Irrigation types
Vegetative surface irrigation is carried out in two ways:
1- Leakage irrigation: In this method, spiral drills (30 ° -40 ° F) and depths of 30 to 35 cm are drilled in the form of spiral joints and the field is drawn into successive hills. The main channel water entering the atmosphere gradually flows into the soil and feeds the available area of the root of the vegetable. These atmospheres are parallel to each other and perpendicular to the slope line of the farm. After passing through the first stream, the water flows into the next stream and reaches the end of the stream. The surface of the area is a few centimeters deep inside the so-called so-called hot water.
2. Crop Method: First, the field surface is converted into small pieces called "groats". During irrigation, the water is separated by small streams of the main creek and transported to Crete.
The irrigation method under the pressure of vegetables is carried out in three ways:
1- Sprinkler irrigation
This method is common in high-level vegetables. Devices such as a water pump, galvanized and galvanized main tubes are used with chimneys. Sprinkler irrigation is also used to prevent cold weather. Saving water and no need for leveling the land are the benefits of this method. In areas of intense winds, the water does not even spill on the field.
2- Dip irrigation
Vegetable irrigation is carried out using plastic pipes in this way, which is common today in many concentrated crops. On the pipes, there are built-in holes in which the dropper is installed and the water drips in the area available to the roots of the plants. These vegetables can be irrigated by irrigation strips known as the type bar, and with drip tubes, the choice of this method depends on the designer of the irrigation system and the type of vegetables and the amount of the budget. If this method allows us to reach 25% of the roots of the plant in the water field, the plant can continue to grow normally. This method saves a lot in water. Pipes are made of black plastic, which is cheaper and because of their blackness, algae can not grow on it. The disadvantages of this method are the eclipse of emitters and tubes.
3. Underground irrigation
The tubes are embedded in the basement, where moisture is rooted to a depth of 30 to 60 cm from the soil. In the event of intense rainfall, these pipes act as drafts.
