摘要
在渗灌条件下,研究了包膜控释尿素施入方式对樱桃番茄产量和品质的影响。结果表明:集中施肥可提高果实产量和品质。以垄内沟施翻埋15 cm效果较好,较对照增产14.49%,果实可溶性固形物和Vc含量分别提高0.51%和49.0 mg/kg,硝酸盐含量降低1.97 mg/kg。
The effect of different application methods of contolled released urea coated with membranes on cherry tomato yield and quality under the percolation irrigation were studied. The results showed that normal concentrated fertilizer could increase the cherry tomato yield and quality, and shallow furrow applying at 15 cm depth was better than the other methods. The yield, the soluble solid content and the Vc content of cherry tomato increased 14.49%, 0. 51% and 49.0 mg/kg respectively, and the nitrate content was decreased 1.97 mg/kg.
