摘要
从营养元素和植物生长物质两个方面研究了NPK配施、硼、磷酸二氢钾、2,4-滴、烯效唑和钼酸铵对甜养形态指标、结实率和产量的影响。结果表明:①硼砂A、2,4-滴在一定程度上降低了株高;②钼酸铵使开花总数增加,硼砂与2,4-滴能减少开花总数:③各处理均能提高结实率,其中以钼酸铵为最高,钼酸铵>硼砂B>磷酸二钾>N+PK>2,4-滴>烯效唑>N>硼砂A>对照;④钼酸铵、N+PK、硼砂B、磷酸二钾、烯效唑和2,4-滴能极显著提高产量,N也可显著提高产量。
The results showed as follows:(1) B(A) and 2,4-D can shortened the plant height of F.esculentum to some extent;(2) ammonium molybdate can increase the quantity of blooming flowers,B and 2,4-D play an inverse role;(3) the seed setting rate of all treatments increases compared with that of the CK and the increasing sequence is ammonium molybdate >B(B) >KH_2PO_4>N+PK >2,4-D>Uniconazole>N>B(A)>CK.(4) Ammonium molybdate,N+PK,B(B),KH_2PO_4,uniconazole and 2,4-D can improve the yield of F.esculentum very significantly.N can improve the yield significantly.
