ABSTRACT A field study was conducted in a randomized complete block design over two growing seasons. The objective was to evaluate the effect of supplementary nutrients, in addition to standard fertigation practices, on fruit yield and quality for annual plasticulture strawberry production. First season treatments included i) a root applied secondary macro and micronutrient mix (0-0-0) + foliar applied nutrient (6-4-3) ii) foliar applied nutrient (6-4-3) and iii) nontreated control. Additional treatments in the second season included root applied micronutrient mix alone, and a foliar nutrient application of an OMRI certified cold-processed sweetener. Treatments were replicated four times using ‘Chandler’ strawberry. Plugs in the root applied treatment were lightly dusted with the nutrient powder just before transplanting. Foliar nutrient was first sprayed at 30% bloom and every 7 to 14 days as frequent harvesting began. There were no significant differences among treatments for yield, fruit size, firmness or total soluble solids content.

评估补充营养素以提高草莓果实质量和产量

摘要 在两个生长季节的随机完整区组设计中进行了实地研究。目的是评估除标准施肥实践外，补充养分对年度可塑性草莓生产的果实产量和质量的影响。第一季处理包括 i) 根施次要常量和微量营养素混合物 (0-0-0) + 叶面施肥 (6-4-3) ii) 叶面施肥 (6-4-3) 和 iii) 未处理对照。第二季的其他处理包括单独使用根部微量营养素混合物，以及使用 OMRI 认证的冷加工甜味剂进行叶面营养。使用“钱德勒”草莓进行四次重复处理。就在移栽前，用营养粉轻轻撒上根应用处理中的栓塞。叶面养分首先在 30% 开花时喷洒，随着频繁收获开始，每 7 至 14 天喷洒一次。在产量、果实大小、硬度或总可溶性固形物含量方面，处理之间没有显着差异。
