CCTV News: "Good rain knows the season, and spring will happen." February 18th will usher in the Rainwater solar term. During the rainy season, the temperature in most parts of my country is warming up, the snow is getting less and the rain is getting more and more, and everything is still enjoying the moistness of the spring rain, and a new spring is coming.

For agriculture and agriculture, the rain season is a critical period for small spring management and big spring preparation. Farmers from all over the country seized the farming season and began to prepare seeds, harvest, field management and maintenance in spring. Ten thousand mu of lychees will produce new leaves, strengthen management and maintain stable harvest

Guangdong is the largest lychee production area in my country, with a lychee planting area of ​​4 million mu. After the Spring Festival, lychee trees in many places already have buds, and growers are busy scientifically managing lychee trees.

During this period, in this lychee forest in Zengcheng, Guangzhou, new leaves have grown one after another, and many lychee trees have buds. In a few months, the trees here will be full of red lychees. Flowers bloom well and bear good fruits. Be busy with spring management during the farming season.

Only good flowers can produce good fruits. As the largest lychee producing area in my country, Guangdong has significantly increased heavy rainfall for a long time in autumn after lychee picking in 2023, and there is insufficient low temperature weather in winter, which has led to the fact that many lychee trees did not bloom after the spring of 2024, and many lychee varieties have significantly reduced their yields in the later period. Some varieties such as Guiwei and other production are less than 10% of the previous year, and the output of more than 200,000 mu of lychee in Zengcheng has also been greatly affected.

But in 2025 is different. Now, the buds on the lychee trees are more obvious, and they are basically spent in rows and strings. This is a lychee tree with a variety of immortals. Its crown is semi-open and has been improved and is now relatively short and strong. If you look closely, this small green on the branch is the inflorescence, and its inflorescence is relatively short, usually 15-25 cm. The flowers include male, female and bisexual flowers, among which female flowers bear the most fruits. Growers said that compared with the same period in 2024, the current flowering rate of lychee trees has increased significantly compared with last year. Drone spraying operations have greatly improved efficiency

The consumption rate is high, and careful maintenance is indispensable. At present, it is a very important stage in the early stage of lychee blossoms, especially in the prevention and control of diseases and pests. Nowadays, the orchard uses drones to spray large areas of lychee trees. In the past, it was artificially sprayed on lychee trees one by one. It was not only time-consuming and labor-intensive, but also very unevenly sprayed from high to low. We can calculate the time account. In the past, 6 people took 3 days to complete the work of a hundred acres of land here. Now, it only takes 3 hours for a drone per person, and the spraying is more even. It can be said that under the promotion of technology, the time of maintenance of lychees has been greatly shortened, but the efficiency has been greatly improved.

Another feature of field management here in 2025 is that it pays more attention to ecology. The drone sprays trace elements and enzyme preparations necessary for the growth of lychees. Trace elements can improve the plant's ability to resist insects and prevent diseases, while enzyme preparations can improve the categories and activities of beneficial bacteria. Through biological enzyme preparations, they can use bacteria to treat bacteria and bacteria to inhibit bacteria, thereby achieving the effect of preventing and treating diseases.

Although lychee trees are just coming to flowers now, the local cultural and tourism departments have begun to promote and use lychees as a medium to develop a tourism development model of appreciating flowers in spring and savoring fruits in summer. In about a month, the garden will bloom all over the place, and after another 4 months, red lychees will hang on the branches.
