The Jino people are primarily upland rice planters who practice crop rotation agriculture on Jinuo Mountain. According to the survey, more than 100 upland rice varieties in Jinuo Mountain before the 1950s. Despite the loss of over 30 traditional upland rice types, there are still 71 varieties remaining, including 16 early-maturing varieties, 35 medium-maturing varieties, 20 late-maturing varieties, and 25 glutinous rice varieties. The Baya upland rice types are the most numerous in the region, totaling 38. Along with allocating different crop varieties according to altitude and climate, Jino people's traditional ecological customary law of crop and land allocation frequently set the cultivation ratio of early, middle, and late rice upon a piece of land, which can be avoided to a period of short supply and food scarcity occurs. And by utilizing a variety of varieties, different types of land, different years of planting with different varieties, according to local conditions, and crop rotation, the goal of making the best effort and ensuring the harvest may be accomplished. The following table summarizes the common regulations for upland rice varieties and land types used by Jino people, which reflect one component of their traditional ecological customary law for crop rotation agriculture (**Tables 1**–**3**) [23].

In the villages of Jinuo Mountain, the variety of upland rice varieties and land type distribution regulations are significantly more varied than those represented in the table above. Because the soil is deep and fertile, even a tiny plot of land may support a variety of crops or variants of the same crop. There are other comparable incidents of the Jino people in Yunnan's Xishuangbanna. For example, the traditional ecological customary law of the Honghe Hani people's terraced agriculture protects and promotes rice variety genetic diversity. In contrast, the old ecological customary law of Diqing's Tibetan plateau agriculture protects and develops the highland barley variety. Enhancement and enrichment of genetic variety, among other things.
