High-efficiency disinfection treatment method for strawberry elevated cultivation substrate

Abstract

The invention discloses a high-efficiency disinfection treatment method for a strawberry elevated cultivation substrate. The method comprises the following steps: (1) pulling up strawberries in an elevated substrate in late April, removing a cultivation trough mulch, deeply ploughing the cultivation trough substrate, and pulling out strawberry plant root systems; (2) in early May, adding a bactericide to the substrate, turning over the bactericide and the substrate for uniform mixing, and thoroughly watering the substrate to make the water content of the substrate at 70-80%; (3) covering a cultivation trough with a film with a matched width immediately, after the covering for 25 to 30 days, revealing the film for deflating for 15 to 20 days; and (4) spreading a microbial agent and an organic fertilizer to the substrate, performing uniform mixing, thoroughly watering the substrate, allowing the watered substrate to stand for 10-15 days. The method disclosed by the invention solves the problem that an elevated cultivation substrate has heavy pests and diseases during continuous cropping and disinfection is time-consuming and labor-intensive, enables the cultivation substrate to be recyclable and improves physical and chemical properties of the substrate, and also the application scale of elevated substrate cultivation can be expanded, and the planting efficiency is improved.

Description

technical field [0001] The invention relates to a method for treating cultivation substrates, in particular to a method for disinfecting strawberry cultivation substrates. Background technique [0002] Substrate is the basis of soilless cultivation, according to statistics, 90% of the world's soilless cultivation forms are substrate cultivation. Soilless culture substrate is a growth medium that can provide plants with a stable and coordinated water, air, and fertilizer structure. In addition to supporting and fixing plants, it is more important to act as a carrier of nutrients and water. At present, with the development of high-efficiency agriculture in China, especially the rapid development of urban agriculture, strawberry substrate cultivation has developed rapidly. [0003] After the substrate used for strawberry cultivation is used in one stubble, due to the gradual increase in air, irrigation water, root secondary metabolites and pathogens contained in the substrate ...
