How is lettuce grown in high yield? Lettuce is one of the more common vegetables on our table. With the increasing number of people who have eaten lettuce in recent years, the market demand for lettuce is broad and wide, and the farmers who grow lettuce are gradually increasing. What? What are the advantages of micro sprinkler irrigation? Let's take a look at the Xiaonong.com. First, the high-yield planting technology of lettuce To grow lettuce, only scientifically master the cultivation management techniques of lettuce can further increase the yield and economic benefits of lettuce. 1. Since lettuce is a kind of hi-fat vegetable variety, when selecting a field planting, it is necessary to select soil with soft soil and good fertilizer and water retention, which is conducive to high-yield lettuce cultivation. 2. After the lettuce is planted and planted, it should be watered first. This can play a role in relieving the seedlings. If conditions permit, the membrane can be used for irrigation when planting in the greenhouse. This can effectively reduce the humidity in the greenhouse and help the lettuce to increase production. The effect of increasing income. 3. After planting the seedlings, it is necessary to wait until the true leaves of the lettuce grow to eight or nine pieces, and start to pursue the strong seedlings. 4, 2 weeks later, when the lettuce grows into a cluster, the second top dressing can be carried out, which is conducive to the growth of the leaves and leaves. 5, when the stem of the lettuce begins to expand, and then topdressing once, this is conducive to promote the fleshy stem hypertrophy, and then there is no need to topdress. Second, the advantages of lettuce planting micro-sprinkler irrigation The most suitable irrigation method for lettuce cultivation is micro-sprinkler irrigation, which can save water resources. Micro-irrigation is mainly used to deliver pressurized water to the field through low-pressure pipelines, and then spray irrigation water on the surface of the soil through micro-sprinklers or micro-spray belts directly mounted on the capillary tubes or connected to the capillary tubes. When watering, the water flow is sprayed out by the micro-spray at a large flow rate, and is pulverized into small droplets under the action of air resistance to land on the ground or crop leaves. The atomization degree is smaller than that of sprinkling irrigation, and the advantages of micro-sprinkler irrigation are mainly There are the following points: 1. Save water, increase the utilization rate of irrigation water, and reduce planting costs. 2. The micro-irrigation system has strong combination performance and is easy to use. It is mainly reflected in the combination of nozzle and water separator to form a combination of various spray diameters and rainfall intensity, thus adapting to the different needs of fruit trees growing from saplings to trees. 3, energy conservation, compared with other sprinkler irrigation methods, micro-irrigation effectively reduces the system's water supply and lift, fully embodies the role of energy conservation. 4. Control the growth of weeds. When the diameter of the micro-irrigation spray water does not exceed the shade of the trees, the weed growth effect is very obvious. The ground exposed to sunlight does not have water supply, and the weeds are correspondingly reduced.
