核桃为胡桃科胡桃属(Jnglandacae jnglans)中的木本油料树种,在我省已有500多年的栽培历史。我省除海拔较低的干热河谷地区外,其余各地均有分布,主要集中分布于毕节、黔西南、六盘水等地;垂直分布从海拔600～2500米均能生长,多集中在1500～2000米之间。由于我省核桃生长区地形复杂,气候类型多样,在长期的自然选择和不同立地条件影响下,形成种类繁多的生态型和农家品种,种性杂乱,优劣不一。在长期的生产实践中,我
Walnut is a woody oilseed species in Jnglandacae jnglans, which has been cultivated for more than 500 years in our province. Except for the dry-hot valley with lower elevation, the rest of the province is distributed mainly in Bijie, Qianxinan, Liupanshui and other places. The vertical distribution can grow from 600 to 2500 meters above sea level, mostly concentrated in 1500-2000 Between meters. Due to the complex terrain and climate types in the growing area of walnut in our province, under the influence of long-term natural selection and different site conditions, a great variety of ecotypes and farmhouse varieties are formed, with different species and different quality. In long-term production practice, I
