Advantages Of Drip Irrigation And Fertilization

One of the best water-saving irrigation technologies has attracted the attention of growers. In recent years, dripper irrigation has attracted great attention and has been unprecedentedly popularized, and its development speed is faster than expected.

Compared with conventional fertilization methods, agricultural drip irrigation has the following advantages:

1.Save labor

In the production of fruit trees, water and fertilizer management consumes a lot of labor. For example, in some banana producing areas, the annual fertilization frequency reaches 18 times. Dig holes or open trenches for each fertilization, and irrigate after fertilization. Simultaneous management of water and fertilizer after using facilities for irrigation and fertilization saves a lot of labor. Now that labor prices are getting higher and higher, the application of irrigation and fertilization technology can significantly save production costs.

2. Increase fertilizer utilization

Water and fertilizers are transported directly to the root system, allowing full use of nutrients and rapid absorption of the root system. Because the water and fertilizer solution is evenly distributed in the soil, the nutrient distribution is highly uniform, and the absorption efficiency of the root system is improved. Traditional fertilization and irrigation are carried out separately. After the fertilizer was applied to the soil, due to the lack of timely irrigation or insufficient irrigation, the fertilizer was present in the soil and the root system was not fully absorbed. Under the field drip irrigation and fertilization system, the nitrogen utilization rate is high, which can reach 90%, phosphorus can reach 50 ~ 70%, and potassium can reach 95%. Increased fertilizer utilization means less fertilizer applied, which saves fertilizer.

3. Precision fertilization

Irrigation drip line supplier believes that: Drip irrigation can flexibly, conveniently, accurately, and quickly control the amount and time of fertilization, and can be targeted to fertilize according to the nutritional laws of crops. . For example, the fruit tree mainly needs nitrogen in the tapping stage; a variety of nutrients such as nitrogen, phosphorus, and potassium are needed in the young fruit stage; and the demand for potassium increases during the later stages of fruit development. According to the nutrient characteristics of the crop, it can provide complete nutrition for the crop and complete the fertilization task in a short time. The growth rate of the crop is uniform, which is convenient for the management of the farm and orchard.

4. Improve the soil environment

The uniformity of drip irrigation irrigation can reach more than 90%, which overcomes the soil compaction which may be caused by irrigating and drip irrigation. Drip irrigation can maintain good water and gas conditions, and basically does not damage the original soil structure. Because soil evaporation is small and soil moisture is kept for a long time, soil microorganisms grow vigorously, which is beneficial to soil nutrient transformation. With drip irrigation and fertilization, crops can be grown on barren land. Such as sandy land, water and fertilizer management is a big problem, and it is often difficult for crops to grow normally. With drip irrigation and fertilization, crops can be grown normally under these conditions. Foreign countries have used the advanced drip irrigation and fertilization technology to develop deserts and successfully cultivated commercial crops. Israel has widely applied drip irrigation and fertilization technology to produce sweet peppers, tomatoes, flowers, etc. in the southern desert, and has become a well-known "vegetable basket" base in Europe in winter. Through the application of drip irrigation and fertilization technology, high-quality cantaloupe was planted on a large area in the sand.

5.Improve the ability of crops to resist disaster risks

Drip irrigation provided sufficient water and fertilizer supplies, balanced water and fertilizers, good crop growth, and improved disaster resistance. If the drought lasts for a long time, crops with drip irrigation and fertilization will have high yields and stable yields, while artificially irrigated land will have poor growth conditions and low yields.

6. Conducive to protecting the environment

Fertilizer utilization is low. Due to unreasonable fertilization, huge waste of fertilizer is caused. A large amount of fertilizer is not absorbed and used by crops and enters the environment, especially water bodies, thus causing eutrophication of rivers and lakes. Controlling irrigation depth through drip irrigation can avoid leaching of chemical fertilizers to deep soils, which can cause soil and groundwater pollution, especially the leaching loss of nitrate nitrogen can be greatly reduced.
