经过在湖南省的小面积引种试验,筛选出表现优良的铁粒头、石丰、九家种3个板栗品种。以湖南省主要农家品种——它栗作对照,进一步进行品比试验,获得了与小面积引种栽培试验基本一致的结果;与此同时,还进行了多点试验,参试品种的丰产性能在不同试验点表现基本一致;历时14年的引种试验证明,这3个品种在湖南省自然条件下生长、结实良好,引种获得了成功。
After a small area introduction test in Hunan Province, we screened three chestnut varieties with high performance, such as Tiegutou, Shifeng and nine species. Taking the main peasant variety-its chestnut as control in Hunan Province, the further comparison test was carried out, and the result was basically consistent with that of the small-area introduction and cultivation experiment. At the same time, the multi-point experiment was also conducted, The performance of different test points was basically the same. After 14 years of introduction test, these three cultivars grew well under the natural conditions in Hunan Province and achieved good results.
