Abstract

The present invention provides a substrate-cultured strawberry irrigation and fertilization method and system. The method comprises the following steps: determining a strawberry growth period according to a strawberry growth image and determining a strawberry fertilization scheme corresponding to the strawberry growth period; calculating the substrate water content of cultured strawberries based on a substrate water holding model according to substrate capacity, environmental factors, and technical parameters of irrigation of the cultured strawberries and a strawberry growth period; If the substrate water content is smaller than or equal to a preset strawberry irrigation threshold value, determining a strawberry irrigation scheme according to the substrate water content, substrate hydraulic characteristics and the strawberry growth period; and fertilizing and irrigating the strawberries according to a strawberry fertilization scheme and the strawberry irrigation scheme. The method andsystem comprehensively consider influence of the substrate capacity, environmental factors, and technical parameters of irrigation of the cultured strawberries and the strawberry growth period on thesubstrate water content, and more in line with water and fertilizer requirements of the substrate strawberries at different growth stages, and improve a water and fertilizer utilization rate.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method and system for irrigation and fertilization of substrate-cultivated strawberries. Background technique [0002] Facility cultivation of strawberry uses facility conditions to regulate environmental conditions and improve the growth and development period of strawberry, so as to achieve the purpose of artificially regulating strawberry production. Strawberries are listed in the off-season and sold off-season. This method makes strawberries have higher economic and social benefits. However, the fixity of cultivation facilities makes the problem of repeated cropping of strawberries increasingly prominent. Soilless cultivation can overcome strawberry continuous cropping obstacles and soil-borne diseases and insect pests, and is widely used in strawberry facility cultivation. [0003] Substrate cultivation is the main method of strawberry soilless cultivation. Th...
