Advantages and disadvantages of drip irrigation
1. Under high water use drip irrigation conditions, irrigation water can wet part of the soil surface, thereby effectively reducing inefficient evaporation of soil moisture. Meanwhile, the soil moisture content is lower in other areas, so only soil wet near the roots of the crop drips, thus preventing weed growth. The drip irrigation system does not cause surface runoff, and it is very easy to figure out the exact application depth of water which is water saving.
2 Drip irrigation After low humidity environment, good soil permeability root conditions, by pouring water into the fertilizer, stability and low adsorption condition need crops, soil moisture enough to meet the evaporation area of irrigation volume or It can provide nutrients and can reduce the frequency of pesticides within the protection, which can effectively control the humidity within the protection, so that the frequency of occurrence of pests on the protected crop is greatly reduced .
3 It can improve and enhance crop yield and improve the quality of agricultural products, while at the same time providing irrigation water supply timely, improving the quality of products for appropriate amount of fertilizer crops, protection of agricultural rate Territory greatly improved the high economic efficiency.
Four. Suitable for different types of soil plots with drip irrigation and terrain undulations, a powerful emitter that can operate over a wide operating pressure range and the ability to drip to adapt to the terrain and soil, and emitter outflow uniformity. At the same time, drip irrigation can reduce cultivation and weeding without causing compaction of the ground.
Five. Save water and labor, increase production and increase income. Because the irrigation water is not air and the wet leaves are not moving, the soil surface is not other than the effective area of moist evaporation, so the amount of water is directly lost to evaporation minimum, easy to control the amount of water, It will not produce deep surface runoff or leaked soil. Therefore, it can save 35% -75% water compared to sprinkler irrigation. It has opened new avenues of water conservation in mountainous areas where water sources and water shortages are low. Because not enough water is supplied between the lines and therefore, it is difficult to grow the crop against nutrient weed competition, reduced labor weeding to significantly reduce interference and with weeds. The crop's rhizosphere can maintain the best water supply and fertilizer status, thus increasing production.
6 Drip irrigation systems are expensive. Capillary drippers are blocked by the effects of impurities and mineral precipitation; uniformity of drip irrigation is not easy to guarantee.
