摘要:
本研究针对6种施肥配方对西昌红颜草莓园艺性状、外观性状、果实品质的影响进行了研究,为当地农户延长草莓生产期提供理论依据。结果表明:施用大量元素水溶肥(15-35-10+TE)的表现较优。大量元素水溶肥(20-10-20+TE)可促进新叶生长,单株达4.33片;大量元素水溶肥(15-35-10+TE)对草莓叶绿素、果实纵横径、果形指数、单果重的影响明显优于其他处理,叶绿素最高达73.80 SPAD,最大纵径为3.33cm,最大横径为2.60cm,单果重达10.40g;大量元素水溶肥(10-5-35+TE)可促进草莓开花,单株达7.67朵;大量元素水溶肥(20-10-20+TE)+硫酸亚铁可提高果实硬度,达1.76kg/cm2;大量元素水溶肥(20-10-20+TE)+硫酸锌可提高果实可溶性固形物含量,最高达17.52%。

Effects of Different Plant Regulators on Horticultural Characters of ‘Hongyan’ Strawberry
()
Abstract:
The effects of four plant growth regulators on the growth, appearance, soluble solid content and hardness of strawberry were studied. The results showed that exogenous brassinin could increase the chlorophyll content and the number of new leaves of strawberry to a certain extent. The chlorophyll value per plant reached 50.16SPAD, and the number of new leaves reached 7.67. The number of flowers, the vertical and horizontal diameter of fruit and the weight of single fruit increased significantly. The maximum number of flowers per plant reached 10.00, the maximum longitudinal diameter reached 3.45cm, the maximum transverse diameter reached 2.91cm, and the single fruit weight increased by 5g compared with CK. The content of soluble solids was significantly increased by inducer, which reached 15.99%. At the same time, inductin could maintain the fruit hardness better, and the hardness reached 1.52kg/cm2.
