长寿沙田柚系四川省长寿县地方名特产品。1985和1989年连续两届被评为全国优质水果,1988年又应邀参加日内瓦“第一届国际植物新品种展览会”。但因其自花结实率低,影响了农民的经济收益和发展的积极性,为提高沙田柚的结实率,我们于1987年利用当地花期基本一致的不同柚类品种花粉进行人工授粉试验,1988年至1989年对初步筛选出来的综合性状较好,且能保持沙田柚基本性状不变的舒氏柚和红心柚两个主要授粉品种,继续进行人工授粉试验,获得了较对照提高着果率80.68—127.27%的良好效果。
Longevity Shatian pomelo is a specialty of Changshou County, Sichuan Province. Two consecutive times in 1985 and 1989 were rated as the national high-quality fruit, was invited to participate in 1988 in Geneva, “the first International Plant Variety Exhibition.” However, because of its low self-planting rate, affecting farmers’ economic returns and enthusiasm for development, in order to increase the seedling rate of Shatian pomelo, we conducted artificial pollination experiments in 1987 using pollen of different pomelo varieties with basically the same flowering period in our country. By 1989, the two main pollination varieties of Shuzai pomelo and Hongxin pomelo, which had been screened out well, were able to maintain the basic traits of Shatida pummelo, and the pollination experiments were continued. The fruit yield was 80.68 -127.27% good effect.
