Influence on the sugarbeet seed yield and quality by rare aerth boric fertilizer with highly efficient formulation

江苏省湖西农场为采种甜菜种植老区， 为进一步提高种子产质量，进行了高效配方稀土硼肥用于采种甜菜的对比试验，结果表明：施用高效稀土微肥处理的种株越冬成活率、千粒重分别较对照提高１ ．８ ～２ 个百分点、１．８ ～２ ．２ｇ；种子产量与发芽率处理与对照比分别提高１８ ．７ ％ ～２０．６ ％ 、７ ．８ ～８ ．２ 个百分点。

Huxi farm is a old areas for sugarbeet seed collecting in Jiangsu Province, for getting high yield and high quality, the comparing tests have carried out by rare earth Boric fertilizer with highly efficient formulation,the results have shown that the overwintering survival ratio of seed plants and 1000 seed weight can increasing 1.8～2.0 percentage points, 1.8～2.2 g than CK, the seed yield and germinating ratio increasing 18.7%～20.6%,7.8～8.2 percentage points the best methods should be seed dressing,and sprayed during flowering period.
