In recent years, litchi has become the “golden sign” of Guangdong agriculture and the pillar industry of fruit. The high-quality development is inseparable from a group of “gardeners” from South China Agricultural University. The post-storage trinity model has promoted the litchi industry to become a high-quality, reputation, and high-value agricultural golden sign.

Breeding good varieties to improve quality, value, and efficiency

  The College of Horticulture has developed or integrated excellent new varieties + low-level branch grafting and planting technology to meet the technical requirements for the adjustment of the variety structure urgently needed in the litchi industry. It has successively selected 8 new litchi varieties and formulated the UPOV international standard related to litchi1 Item, using new varieties to extend the production period of litchi in the same producing area by 40 days. National Litchi and Longan Industry Technology System Litchi Variety Improvement Post Expert Professor Hu Guibing’s team led the selection of a high-quality extra-large-fruit lychee hybrid new line'Jumeiren' that has recently undergone on-site evaluation. The fruit is extraordinarily large (average single fruit weight 50.7 grams, maximum single fruit weight 68.0 grams ), the color is bright red, and the texture of the flesh is crisp and tender. It has been unanimously recognized by the National Committee of Experts on Major Scientific Research Joint Research on Litchi Varieties. It is recognized as a breakthrough in lychee hybrid breeding and has great potential for promotion and application. The project of Dean Hu Guibing's team also won the first prize of Guangdong Science and Technology Progress Award.

  Lightweight and high-efficiency cultivation promotes increased production and income.

  This should be one of the first and most delicious glutinous rice dumplings in the world! Professor Li Jianguo, a scientist at the Litchi Cultivation Post of the National Litchi and Longan Industrial Technology System, said happily in an interview with a reporter from the Southern Rural Daily in Yangdong. Professor Li Jianguo has successively overcome key technical problems such as the supply of early-maturing lychee fresh fruit, integrating the “early maturity, early control of shoots, early flowering, early maturity” (referred to as “four early”), light and high-efficiency cultivation techniques for Nuomi Litchi, and was evaluated As a national outstanding talent in agricultural scientific research, the project he presided over was also awarded the second prize of the National Science and Technology Progress Award. In recent years, the efficient and safe production technology of litchi developed by the College of Horticulture has been successfully applied, reducing the annual fluctuation of litchi flower formation rate to below 30%, increasing fruit setting rate by 10%-20%, reducing fertilizer consumption by 40%-50%, and reducing labor costs. 35%-45%, play an important role in increasing production and income of farmers in production areas and regional economic development.

  Deeply cultivate fresh-keeping technology to enhance industrial efficiency.

  Beginning with Mr. Li Peiwen, after several generations of gardeners, the achievements with Litchi post-harvest processing and preservation logistics integrated technology as the main content have won two second-class national scientific and technological progress awards. This technology has opened up the lychee Southern China. The Last Kilometer of Guobeiyun has successfully exported lychees to many European and American countries, which has improved the level of industrial technology. The College of Horticulture has signed co-construction cooperation agreements with a number of litchi industrial parks, set up field expert workstations in many places, and successively guided more than a dozen companies in litchi production and post-harvest treatment, in order to improve the efficiency and competitiveness of my country's litchi industry and improve farmers The employment rate and poverty alleviation have made a significant contribution. 

 Litchi post-harvest treatment

  In recent years, the College of Horticulture has strengthened school-local cooperation and school-enterprise cooperation based on platforms such as the national key discipline of fruit tree science, the national technology system for litchi and longan industry, the Guangdong Key Laboratory of Fruit and Vegetable Preservation, and the Guangdong Litchi Engineering Center. Xianyi, Shuangli and other well-known lychee brands have accumulated new sales of 4.99 billion yuan in the past three years and new profits of 3.423 billion yuan. The coverage of high-quality varieties has increased to 45%, which has promoted the adjustment of the structure of lychee varieties. Industrial upgrading.
