Abstract

The invention discloses a special formula fertilizer for soilless culture lettuce and a preparation method thereof. The special formula fertilizer for soilless culture lettuce comprises a fertilizer A and a fertilizer B, wherein the fertilizer A is compounded from the following components in percentage by weight: 75-84% of calcium fertilizer and 16-25% of magnesium fertilizer; the fertilizer B is compounded from the following components in percentage by weight: 77-80% of major element fertilizer, 11-15% of minor element fertilizer, 5-8% of buffering agent and 1.4-2.0% of functional additive; and the nitrogen content in the fertilizer A is 14.2-14.7wt%, the calcium oxide content is 19.8-22.2wt%, and the magnesium oxide content is 2.4-3.8wt%. The special formula fertilizer for soilless culture lettuce contains comprehensive nutrients, has a high nutrient utilization ratio, realizes that the pH value of the nutrient solution system can be regulated and controlled in an intelligent manner, can effectively prevent interreaction of ions in the nutrient solution, ensures the stability of the nutrient solution, and is convenient to apply; and the whole fertilizer compounding operation can be completed within one container, thereby achieving the advantages of time saving and labor saving.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a special formula fertilizer for soilless cultivation of lettuce and a preparation method thereof. Background technique [0002] Soilless cultivation, broadly speaking, any method that does not use natural soil but replaces soil with other substances can be called soilless cultivation. Therefore, there are various forms of soilless cultivation, such as hydroponics, fog cultivation, matrix cultivation, rock wool cultivation, pipe cultivation, three-dimensional cultivation, column cultivation, wall cultivation and so on. Compared with conventional soil cultivation, soilless cultivation has the following advantages: (1) The planting area is not restricted by land. Rocky mountains, deserts and other barren lands can also grow crops, and even roofs, balconies, corridors, window sills, etc. can also be used. (2) The crop yield is high and the quality is good. Because so...
