Sweetening technology for cultivating strawberries

Abstract

The invention relates to a sweetening technology for cultivating strawberries.The sweetening technology includes that strawberry plants with one-year growth phases are selected to be used as colonization seedlings, Nitro-plus 9 is sprayed on strawberry leaf surfaces after the strawberry plants are colonized and before the strawberry plants bloom, sweetening fertilizers are applied after strawberry floral buds appear and before flowers wither, sweetening spray agents are sprayed on strawberry fruits and the strawberry leaf surfaces once on a daily basis after the strawberry plants bear the strawberry fruits, and rhodopseudomonas palustris liquid is sprayed on the strawberry fruits and the strawberry leaf surfaces once on a daily basis after the strawberry fruits turn red.The sweetening technology has the advantages that fragrance of the strawberry fruits can be improved, the single-fruit weight of the strawberries can be increased, the sweetness of the strawberries can be improved by means of day and night temperature control, the sweetness of the strawberries cultivated by the aid of the management technology can be improved by 1.2-1.5 degrees, and the yield of the strawberries in each mu can be increased by 38-40%.

Description

technical field [0001] The invention relates to the technical field of vegetable and fruit planting, in particular to a strawberry sweetening planting technology. Background technique [0002] Strawberry is a relatively delicate fruit that has high requirements for the growing environment. At present, it is mostly planted in greenhouses. Sunshine, ventilation, rain, etc. will all have an impact on the sweetness of strawberries. For example, fewer sunny days and too many rainy days may lead to Insufficient nutrient accumulation of strawberries leads to weak taste and decreased sweetness. In recent years, due to excessive fertilization of the soil, soil compaction and loss of nutrient elements have been caused. The cultivation method is too single, and only rely on regular fertilization and watering for management, resulting in loss of strawberries. In order to change the situation of strawberries not being sweet, some growers began to use various hormones. Although the sugar ...

The cultivation method is too single, and only rely on regular fertilization and watering for management, resulting in loss of strawberries. In order to change the unsweetened status of strawberries, some growers began to use various hormones. Although the sugar content has increased, the harm of hormones to people will also follow.
