为了及时鉴定全国柑桔良种的区域适应性,提出适合我省黔南低热地区栽培的柑桔优良品种,供生产上应用。我所于1974年参加由中国农科院柑桔研究所主持的全国柑桔良种区域化试验。 试点位于罗甸城郊本所内,海拔430公尺,约在北纬25度左右,东经106～107度之间,全年气候温和,常年平均气温19.6℃,7月最高均温为26.8℃,1月最低均温为9.8℃,≥10℃的年积温为6488.6℃,最低气温多年平均值为-1.0℃,为典型的亚热带气候。历年来积雪和冷冻很少,隔十多年偶尔出现一次。年降雨量1300毫米左右,多集中
In order to promptly identify the regional adaptability of the citrus varieties in the country, put forward suitable varieties of citrus cultivars suitable for cultivation in the low-heat area of southern Guizhou, for production application. In 1974, I participated in the National Citrus Variety Regionalization Experiment hosted by Citrus Institute of Chinese Academy of Agricultural Sciences. The pilot project is located in the suburban headquarters of Luodian at an elevation of 430 meters, about 25 degrees north latitude and 106 to 107 degrees east longitude. The climate is mild throughout the year with an average annual temperature of 19.6 ° C. The highest average temperature in July was 26.8 ° C and January The lowest average temperature is 9.8 ℃, the annual accumulated temperature of ≥10 ℃ is 6488.6 ℃, and the average minimum temperature is -1.0 ℃, which is a typical subtropical climate. There have been very few snow and frozen over the years, occasionally occurring once in more than a decade. Annual rainfall of about 1300 mm, and more concentrated
