氨基酸水溶肥(含聚天冬氨酸)在温室草莓上的应用效果

Application Effects of Water-Soluble Fertilizer Containing Amino Acid and PASP on Strawberry in Greenhouse

为了提高温室草莓生产中的肥料利用效率,以河北方舟农业科技股份有限公司生产的氨基酸水溶肥料(含聚天冬氨酸)作为试验肥料,以市售水溶性肥料为对照肥料,在草莓苗移栽定植后通过滴灌系统进行生长期肥料的施用,对温室草莓的整个生长过程、产量、品质及经济效益进行观察和分析。结果表明,自现蕾期开始每隔15 d通过滴灌系统施用氨基酸水溶肥75 L·hm^(-2)(处理2)对温室草莓的整个生长过程有促进作用,能明显降低供试温室草莓的死苗率至5.16%(CK为11.43%);同时能促进其营养生长、提高坐果率至73.38%(CK为56.70%)、促进草莓的提早成熟(与CK相比可提前6 d上市),进而提高果实外观品质(单果重与CK相比提高23.94%、畸形果率由11.28%降至5.60%)和内在品质(可溶性固形物提高44.83%,可滴定酸降低29.49%,VC提高31.99%,果实硬度提高31.67%),显著提高了温室草莓产量和经济效益。

In order to improve the fertilizer utilization efficiency in greenhouse strawberry,the water-soluble fertilizer containing amino acid(including PASP)was used as the experimental fertilizer,and the commercially available water-soluble fertilizer was used as the control fertilizer.After the strawberry seedlings were transplanted and planted,the corresponding fertilizer was applied through the drip irrigation system to observe and analyze the whole growth process,yield,quality and economic benefits of greenhouse strawberry.The resultsshowed that the application of amino acid water-soluble fertilizer 75 L·ha^(-1)(treatment 2)every 15 days from the budding stage promoted the entire growth process of greenhouse strawberries,significantly reducing the dead seedling rate of the tested greenhouse strawberries to 5.16%(CK was 11.43%);At the same time,it can promoted its nutritional growth,increase the fruit setting rate to 73.38%(CK was 56.70%),promoted early ripening of strawberries(which can be listed 6 days earlier than CK),and thereby improve the appearance quality of the fruit(single fruit weight increased by 23.94%compared to CK,abnormal fruit rate decreased from 11.28%to 5.60%)and internal quality(solid content increased by 44.83%,titratable acid decreased by 29.49%,VC increased by 31.99%,and fruit hardness increased by 31.67%),significantly improved greenhouse strawberry yield and economic benefits.
