1、节省劳力
1, save labour.
在果树的生产过程中，水肥管理耗费大量的人工。如华南地区某些香蕉产地的年施肥次数达18次之多。每次施肥要挖穴或开浅沟，施肥后要灌水。利用设施灌溉施肥后水肥同步管理，节省大量劳力，应用灌溉施肥技术可以显著节省生产成本。
In the production process of fruit trees, water and fertilizer management consume a lot of labor. For example, in some areas of Southern China, there are more than 18 times of annual fertilization. Every fertilizing should dig holes or open shallow furrows, and then irrigate after fertilization. The synchronous management of water and fertilizer after facility irrigation and fertilization can save a lot of labor, and the application of irrigation and fertilization technology can significantly save production costs.
2、提高肥料的利用率
2, increase the utilization rate of fertilizer.
水和肥被直接输送到根系部位，可使养分充分利用和根系快速吸收。因水肥溶液在土壤中均匀分布，使得养分分布高度均匀，提高了根系的吸收效率。传统施肥和灌溉都是分开进行的。肥料施入土壤后，由于没有及时灌水或灌水量不足，肥料存在于土壤中，根系并没有充分吸收。
Water and fertilizer are transported directly to the root system, making full use of nutrients and rapid absorption of roots. Because of the uniform distribution of water and fertilizer solution in the soil, the nutrient distribution is highly uniform, and the root absorption efficiency is improved. Traditional fertilization and irrigation are carried out separately. Fertilizer applied to the soil, due to the lack of timely irrigation or insufficient irrigation, fertilizer exists in the soil, the root system is not fully absorbed.
而田间滴灌施肥系统下，氮的利用率高，可达90%，磷可达到50~70%，钾可达到95%。肥料利用率提高意味着施肥量减少，从而节省了肥料。
Under the field drip irrigation system, the utilization rate of nitrogen is high, up to 90%, phosphorus up to 50-70%, and potassium up to 95%. The increase of fertilizer utilization means that the amount of fertilizer is reduced, thus saving fertilizer.
3、精准施肥
3. Precision fertilization
可灵活、方便、准确、快速地控制施肥数量和时间，可根据作物营养规律有针对性施肥，做到缺什么补什么，实现及时精确施肥。例如果树在抽梢期，主要需要氮；在幼果期，需要氮磷钾等多种养分；在果实发育后期，钾的需求增加。可以根据作物的养分特点，为作物提供完全营养，在很短时间内完成施肥任务，作物生长速率均匀一致，方便农场和果园的管理。
It can control the amount and time of fertilization flexibly, conveniently, accurately and quickly, and apply fertilizer according to the law of crop nutrition. It can make up for what is lacking and realize timely and accurate fertilization. For example, fruit trees in the shooting stage, the main need for nitrogen; in the young fruit stage, the need for nitrogen, phosphorus and potassium and other nutrients; in the late fruit development, the demand for potassium increased. According to the nutrient characteristics of crops, it can provide complete nutrition for crops, complete the task of fertilization in a very short time, and the growth rate of crops is uniform, which is convenient for the management of farms and orchards.
4、改善土壤环境状况
4. Improving soil environment.
滴灌灌水均匀度可达90%以上，克服了畦灌和淋灌可能造成的土壤板结。滴灌可以保持良好的水气状况，基本不破坏原有土壤结构。由于土壤蒸发量小，保持土壤湿度的时间长，土壤微生物生长旺盛，有利于土壤养分转化。采用滴灌施肥方法，可以在贫瘠的土地上种植作物。如沙地，水肥管理是个大问题，通常作物很难正常生长。使用滴灌施肥技术后，可保证作物在这些条件下正常生长。
The uniformity of drip irrigation is more than 90%, which overcomes the soil hardening caused by border irrigation and irrigation. Drip irrigation can maintain good water vapor condition and basically does not damage the original soil structure. Soil microorganisms grow vigorously because of the small amount of soil evaporation, the long time to maintain soil moisture, which is conducive to the transformation of soil nutrients. Drip fertigation can be used to grow crops on barren land. In sandy land, water and fertilizer management is a big problem, and crops are usually hard to grow normally. The technology of drip fertigation can ensure the normal growth of crops under these conditions.
5、可提高作物抵御灾害风险的能力
5, increase crop resistance to disaster risk.
滴灌使水和肥料供应充足，水肥协调平衡，作物长势好，提高了抗灾害能力。若干旱持续时间长，应用滴灌施肥的作物丰产稳产，而人工灌溉地长势差，产量低。
Drip irrigation makes the supply of water and fertilizer sufficient, water and fertilizer coordinated and balanced, crops grow well, and improves the ability to resist disasters. Some droughts lasted for a long time, and the crops fertilized by drip irrigation had high and stable yields, while the artificial irrigated land had poor growth and low yields.
