In the mid-1960s, the Fruit Research Institute of Guangdong Academy of Agricultural Sciences began to study the purification, grafting and propagation techniques of citrus varieties. Later, due to historical reasons, the research on citrus grandis was once interrupted. From 1980s to 1990s, marshmallows once again attracted the attention of the local government. The agricultural department started the breeding of excellent cotton candy plants, organized scientific and technical personnel to tackle the problems of flower falling, fruit falling and fruit cracking, and gradually mastered relatively perfect high-yield and high-quality technologies. Cotton candy orange is one of the latest varieties of oranges, which ripens from mid-October to mid-February every year/kloc-0, which coincides with the Spring Festival. Therefore, marshmallow orange has become a veritable holiday fruit. 1996 mashuiju was listed as a "one town, one product" support project by the Guangdong provincial government, which provided more favorable conditions for the development of mashuiju. Yangchun Municipal Party Committee and Municipal Government decided that Lichun Orange is the first choice for developing agricultural economic websites, which can bring considerable economic benefits to farmers. Therefore, unified planning, formulation of supporting policies, and mobilization of the people's enthusiasm for production have led to the rapid expansion of the planting area of Mahuiju, and a number of large-scale production bases have sprung up. The municipal party committee and municipal government took the lead in building ten thousand mu marsh orange demonstration bases in Mashui Town and Guigang Town. Under the radiation of the base, the planting area of marsh oranges has expanded to 16 towns in the whole city, and the planting area of marsh oranges has increased from 30,000 mu in 1995 to 180 mu in 2003, with an annual output of 200,000 tons and an output value of 8.

Thankfully, this high-quality brand Ma Shuiju registered the trademark of "Chunnong" on 200 1, and was certified as pollution-free agricultural products by the Agricultural Products Quality and Safety Testing Center of the Provincial Department of Agriculture in 2002. Yang Chun Municipal Government held product promotion meetings in Beijing and Dongguan, Guangdong, which improved the popularity of oranges.

Nowadays, the municipal government intends to enlarge and strengthen the advantageous industries of cotton candy and increase investment in cotton candy production and scientific research. Mashui Town established Mashui Citrus Research Institute, and hired experts as consultants to carry out technical research. Train and guide fruit farmers to plant ponchos according to pollution-free standards. With its excellent quality, it has an advantage in market sales. Spring Festival is the harvest season of Mashuiju. Merchants from Beijing, Shenyang, Lanzhou, Shanghai, Guangzhou, Fuzhou and Haikou flocked to buy Mashuiju. In just a few days, the harvested 200,000 tons of Sargassum was snapped up. Lichun orange can be stored at room temperature without special equipment, and can be used in ordinary houses and warehouses. The warehouse should be well ventilated, not leaking rain, and the fruit piles will not be exposed to the sun, and it can also prevent rats. Two weeks before storage, the fruit should be sealed, fumigated with sulfur powder (100g/m2) for 24 hours, or sprayed with 4% bleaching powder, and then ventilated for later use. Open all doors and windows when entering the warehouse for the first time, which is beneficial to ventilation and perspiration and heat dissipation of Lichun orange fruit.
