真龙柚异花授粉试验研究

真龙柚是泸州市特色水果，到2012年，全市发展真龙柚基地面积12万亩，产量8000吨，产值5000余万元，其中最集中产区合江县面积达到11万亩，成为合江现代农业发展的主导产业。真龙柚原产于四川省泸州市合江县真龙乡（现密溪乡），系沙田柚芽变优良品种，果肉半透明汁胞绿白色，肉质细嫩化渣，无核，汁较多，无麻苦味，有蜜香味，品质极佳，耐贮藏，品种优良。但由于真龙柚自花授粉形成具有商品性的果实产量较低、果实小、易裂果等突出问题，严重影响了真龙柚的生产发展。为了提高真龙柚产量、解决果实外观和裂果等问题，我们依托国家柑桔技术体系泸州综合试验站，在总结生产实际情况的基础上，从2011年开始对不同授粉品种对真龙柚果实性状影响进行研究，2011年已初步对本地红心柚、本地酸柚、沙田柚等授粉品种进行了试验，形成了真龙柚人工授粉试验初报，并取得较好效果。2012年，我们依托上一年试验研究结果，新增5个授粉品种，进一步深化真龙柚异花授粉试验研究，旨在筛选出适宜真龙柚授粉的品种组合，指导生产发展合理配置真龙柚授粉品种，提高真龙柚种植经济效益。

A study on cross pollination of zhenlong pomelo

In the present study, guanxi pomelo, yuhuan pomelo, longan pomelo, cuixiangtian pomelo, aiwan pomelo were selected as pollination varieties of zhenlong pomelo, and the effects on fruit setting percentage, fruit cracking incidence and the main fruit characters were examined. The results showed that four pollination varieties can significantly increased fruit set, and solve the problem of fruit cracking, and significantly improve the commodity character of fruit. Although seeds were increased, fruit flavor and fruit quality remained to be excellent, and increased yield obviously, It was important significance for promoting industrial development of zhenlong pomelo.
