The Hainan Academy of Agricultural Sciences successfully bred a better-quality japonica rice "Haifengjing No. 1" than the traditional Lilan rice. The variety has the advantages of high yield, disease resistance, cold-resistance, lodging resistance, and good fleas. The average yield per mu is 4 times that of Shanlan rice.

Shan Lan Rice is also known as “Land of Rice,” referring to the fact that Hainan Li nationals have cut a piece of open land in the mountains and fenced it. They planted a kind of dry and indica rice suitable for wine making. The mountain wine is called the champagne of the Li nationality. Therefore, Shanlandao is a favorite traditional crop of the Li nationality.

According to the person in charge of the Institute of Food Crops of the Hainan Academy of Agricultural Sciences, in the central area of ​​Hainan, the long-term cultivation of mountain blue rice not only destroys the ecological environment, but also yields very low. Only one kilogram of mountain blue rice produces more than 100 kilograms. In order to protect the ecological environment and at the same time satisfy farmers' needs for growing japonica rice wines and making specialty foods, Hainan Academy of Agricultural Sciences has been devoting itself to breeding high quality japonica rice that can replace Shanlan rice since 2003.

Through several years of breeding and trial planting, “Haifengjing No. 1” has the advantages of high yield, strong disease resistance, good cold resistance, good lodging resistance, etc., which is far more superior than Shanlan Rice, and the average yield can be Up to 450 kilograms, the yield is 4 times that of Shanlan.

In addition, the "Haifengjing No. 1" has a short growing period. It can grow two crops a year in Hainan, sowing in December, ripening in 145 days, planting in late July, and harvesting in only 117 days. It is very suitable for the promotion of planting in the mountains of central Hainan.

At present, the Institute of Food Crops of the Hainan Academy of Agricultural Sciences has been demonstrating and planting 500 mu in Wuzhi Mountain, Baisha and Changjiang. "Haifeng No. 1" has recently passed the certification of the Crop Variety Commission of Hainan Province.
