South China is a major producing area for tropical and subtropical fruits. The general concept is that precipitation in the south is very rich. Why do we use micro-irrigation and fertilization technology in the south? The first reason is drought. The first is seasonal drought, such as autumn drought and winter drought. In severe cases, it may not rain for 8 consecutive months. In addition, regional droughts, such as the Leizhou Peninsula in Guangdong and the central part of Hainan Island, are severely arid regions. The second reason is that most of the southern orchards are distributed in hilly mountains, and traditional irrigation methods cannot be carried out at all. Irrigation and fertilization are the most labor-intensive jobs in the orchard, and many farmers urgently need simpler irrigation methods. For example, bananas are big water and big fertilizer crops. In some places, fertilization is 18 times a year, irrigation is also very frequent, and now labor is getting more and more expensive, and they are eager to save labor.
In addition to the conventional fertilizer fertigation technology, the yield and quality of the fruit can be improved, and the product grade of the fruit will be greatly improved. Especially for large orchards, it is much easier to apply irrigation fertigation systems for water and fertilizer management, which can be managed centrally. Fertigation is also an important standardized cultivation technique.
The fertigation system can complete irrigation and fertilization in a short period of time, which is of great significance for the management of fruit trees, which is conducive to the uniform flowering and fruiting of fruit trees, and is conducive to the application, pruning and harvesting of other pesticides. In addition, the use of fertigation techniques can solve the problem of the size of the southern fruit trees. The study found that some fruit trees are caused by climatic factors, but more cases are caused by water and fertilizer management. If the management of water and fertilizer is appropriate, the problem of years and years can be solved. Fertilization with irrigation can also reduce the problem of cracking, and some land that is not suitable for planting fruit trees can also be developed to plant fruit trees.
The main facilities for irrigation in South China are pumping drip irrigation, gravity drip irrigation, seepage irrigation, micro-sprinkler irrigation and micro-spray belts. The more used is the gravity drip irrigation system of the orchard, because most orchards in the south are in the hilly mountains, there is a pool above, it is convenient to use gravity for irrigation, and also save investment. We have done demonstration of drip fertigation at Xili Fruit Farm. There are many lychee varieties in the fruit field. We analyze the soil and guide the farmers to irrigate and fertilize. The result is that the yield increase is very obvious. That year was a small year in Litchi, but the litchi tree using irrigation and fertilization technology was a big year. Years of demonstrations have shown that the production of fertigation techniques is higher in Litchi. It can save 70% of fertilizer and save 90% of labor.
