How do crop products "drink water"

Time:2021-08-20   Author:Lemiao Irrigation Equipment

How are the crops growing? Water is one of the main factors. Why do you say that? The simple truth is that just like people need to drink water, crops also need to absorb water. Anyone who has taken the course of science knows that water is one of the basic conditions for photosynthesis of plants. There are also different ways to "drink water" for crops. Let's follow Yuyao Lemiao Irrigation to learn about several common irrigation methods.

【1】Above-ground irrigation: there are mainly two forms of drip irrigation and sprinkler irrigation

(1) Drip irrigation
Drip irrigation is an irrigation method in which water with a certain pressure is filtered through a pipe network and drip irrigation tape or dripper into the soil near the roots of the crop in the form of droplets. Its main advantages are:
1. Water-saving, fertilizer-saving, labor-saving: drip irrigation is a full pipeline water delivery and local micro-irrigation, which can effectively reduce the loss of water. At the same time, it can also provide water to crops in a timely and effective manner and improve water utilization. 
2. Temperature and humidity control: Traditional greenhouse irrigation consumes a large amount of water, and the ground is in a humid state for a long time. The temperature in the shed drops quickly, the temperature recovery is slow, and the amount of water evaporation is large, which is likely to cause crop pests.
3. Maintain soil structure: Drip irrigation belongs to micro-irrigation. Water infiltrates into the soil slowly and evenly, which can maintain the soil structure and form an environment suitable for crop growth.

(2) Sprinkler irrigation
Sprinkler irrigation is an irrigation method in which water with a certain pressure is sprayed into the air with the help of a pump and pipe system or the drop of a natural water source, scattered into small droplets or mist and sprayed on the crops. Simply put, it is "artificial rainfall". Sprinkler irrigation is more common in agricultural applications. Its main advantages are:
1. Save water resources: Sprinkler irrigation can effectively avoid water loss and improve water utilization by controlling the amount of sprinkling irrigation and the uniformity of spraying. Generally, it can save 30% to 50% of water compared with surface irrigation.
2. Labor saving: spray irrigation can realize simultaneous spray irrigation of chemical fertilizers and pesticides, effectively saving labor.
3. Increase production: Sprinkler irrigation can strictly control the moisture of the soil. The moisture of the soil is maintained within the range suitable for crop growth. Sprinkler irrigation can ensure the aeration of the soil. Moreover, sprinkler irrigation can wash away the dust on the crops, which is conducive to photosynthesis, which is conducive to the growth of crops.
4. Strong adaptability: sprinkler irrigation has low requirements for terrain, and it does not need flat land like sprinkler irrigation on the ground.

【2】Surface irrigation: suitable for soils and sections with sufficient water sources, flat land, thick soil layers, and smooth drainage of the bottom of the soil. Surface irrigation is low in investment, easy to implement, and suitable for large-scale vegetable production, but it takes labor and water and tends to harden the soil surface. Here are several forms of surface irrigation:

(1) Border irrigation
It is suitable for vegetables with high planting density or frequent irrigation. Border irrigation requires that the border surface be flat, the border layout is reasonable, and the water flow and discharge time can be controlled. The size of the border, the flow rate of the border, and the length of the water release time are related to factors such as soil water permeability, land leveling and ground slope. The soil has strong water permeability, the land is not level enough or the slope of the ground is small, it is advisable to use short-border large-flow irrigation.

(2) Furrow irrigation
Suitable for most row crops. During furrow irrigation, the moist range of cohesive soil is larger than that of sandy soil, but shallower. In order to make the irrigation water even, the distance, length, and distance of the irrigation ditches should be reasonably determined according to the ground slope, soil texture, and land leveling conditions of the irrigation area. Ditch flow rate and water release time (same as border irrigation).
According to modern requirements, the ground irrigation method should be equipped with an underground water delivery system, which not only saves land, but also prevents water leakage. Set fixed gates on the plots that need to be irrigated to control the amount of water.
This is the end of the content sharing of crop irrigation. Yuyao Lemiao Irrigation is committed to providing better irrigation products and services. If necessary, please inquire and understand. Our company wholeheartedly looks forward to your call.
