富硒樱桃生产技术试验研究

以早大果、红灯、乌克兰大樱桃为材料，研究了同一品种喷施不同浓度、不同次数及不同品种喷施同浓度富硒叶面肥，对樱桃果实硒含量的影响。结果显示：乌克兰大樱桃1000倍液喷施3次后樱桃果实的含硒量最高，达到0．0248 mg／kg ；但无论是1600倍还是1200倍液，在不同时期各喷施2次，其果实硒含量和喷施3次的果实硒含量差异不大。乌克兰大樱桃、红灯和早大果1000倍液喷施3次后，果实硒含量并没有很大差别。

Study on Production Techniques of Rich Selenium Cherry

The Selenium contents of different varieties cherries were studied by spraying different contents and times rich selenium foliar fertilizers on one variety and spraying high selenium fertilizers on different varieties as Zaodaguo、Hongdeng and Ukraine on materials .The result showed that the selenium content of Ukraine fruit were 0 .0248mg/kg with the highest content by spraying 1 000 times liquid ,while the selenium of fruit contents were al‐most same by spraying 2 or 3 times no matter 1 200 times liquid or 1 600 times liquid .The selenium content of U‐kraine、Hongdeng and Zaodaguomade little difference by spraying 1 000 times liquid rich selenium foliar fertilizers with 3 times .
