软枣猕猴桃在贵州引种适应性研究

为丰富和优化贵州省高海拔地区猕猴桃品种结构,筛选出适应贵州气候的软枣猕猴桃品种,从辽宁引进了魁绿、桓优1号等5个品种,种植在贵州省猕猴桃三个主产区,综合评价各品种在各海拔区域的物候期、适应性、果实品质等指标。根据各品种的表现和“合理-满意度”分析,在贵州表现较好的品种有：龙城2号单果重29.89g,果型指数1.35,可溶性固形物19.29,口感香甜,适应性广,抗性强,产量高,可适当发展;辽丹133果实酸甜,糖酸比15.2,口感好,适应性较广,可适当发展;表现一般的有魁绿和桓优1号,魁绿成熟期早,7月中旬采摘上市,口味香甜,产量中等,桓优1号8月中旬成熟,产量高,果实单果重大,但口味一般,果面有果棱,容易受虫害影响,可作为特色果树栽培但不建议大面积栽种;软枣猕猴桃雄株与四个品种花期接近,花粉亲和力强,可作为软枣猕猴桃的授粉品种进行推广种植。

Research the adaptability of Actinidia arguta introduced in Guizhou Province

In order to enrich and optimize the variety structure of kiwifruit at high altitude in Guizhou Province, select the Actinidia arguta Planch Cultivars adapted to Guizhou climate, introduce and screen varieties by introducing techniques, and comprehensively evaluate the phenological period, adaptability and fruit quality of each cultivar at different altitudes. According to the performance and "reasonable-satisfaction" analysis of the varieties, the better varieties in Guizhou are Longcheng No. 2 with 29.89g single fruit weight, 1.35 fruit type index, 19.29 soluble solids, sweet taste, strong adaptability and resistance, high yield and suitable development; Liaodan No. 133 fruit is sweet and sour, sugar-acid ratio is 15.2, good taste and suitable development. It has strong adaptability and can be developed appropriately. Generally speaking, there are Kuilv and Huanyou No. 1 which have better early maturity. They are picked and listed in mid-July with sweet taste and medium yield. Huanyou No. 1 is ripe in mid-August, and can be listed in Kuilv with high yield and single fruit weight, but its taste is general, its fruit surface is corrugated, which has beautiful effect and pests. Heavy, can be used as a characteristic fruit tree cultivation, but not recommended large-scale planting. The male plant of Actinidia arguta is close to the flowering period of four varieties and has strong pollen affinity. It can be used as a pollinating variety of Actinidia arguta to be popularized and planted.
