[0002] Leaf lettuce is the main material for western restaurants and Chinese hot pot. Now, in order to meet the quality of raw food and market demand, most of the cultivation methods of leaf lettuce are hydroponics, substrate, and spraying methods in greenhouses. However, in the greenhouse environment Among them, it provides the best environment for the growth of lettuce downy mildew. In terms of quality requirements, leaf lettuce is not allowed to allow pesticide residues. Currently, for the prevention and treatment of lettuce downy mildew, pesticide disinfection is generally used for seed treatment. Triethylphosphorus aluminum, Ruifu mold, metalaxyl, anti-virus alum, isophosphine mancozeb, Anke mancozeb and other agents are used for prevention and control. The above-mentioned agents are likely to produce residues or cause water pollution, which in turn affects the output products. Therefore, it is necessary to provide a fertilizer that can not only inhibit the activity of preventing downy mildew pathogens, but also provide the trace elements needed for growth and increase photosynthesis

Embodiment Construction
[0015] Attached below figure 1 Explain in detail the process flow of a preparation method for controlling lettuce downy mildew foliar fertilizer
[0016] 1. Material preparation: Take 1000g as an example, raw material I calamus root extract 400g, raw material II is jack bean fermentation liquid 200g, raw material III is chitosan 100g, raw material IV is shell-core structure 120nm titanium micro 30g, raw material V is basil 30g essential oil, 240g emulsifier as raw material VI;
[0017] Among them, the calamus root extract of raw material I consists of 200g calamus root and 400g 52o liquor;
[0018] Among them, the fermented concanavalin broth of raw material II is composed of 100g soft bean pods, 150g brown sugar, 1000g water, and fermented;
[0019] 2. Chop the calamus root and extract with 52o liquor for 7 days. After the extraction, filter the residue to obtain the calamus root extract of raw material I;
[0020] 3. Use the tender pods of canavalia beans and put brown sugar into the...

The invention relates to a lettuce downy mildew preventing and treating leaf fertilizer which comprises the following components in percentage by weight: 40-50% of acorus calamus root leaching liquid, 20-25% of sword bean leaching liquid, 10-15% of chitosan, 3-5% of core-shell structured 120nm titanium microsphere, 3-5% of basil essential oil and 24-30% of emulsifier, wherein the components are processed and prepared into emulsion. During the use, water is added to the lettuce downy mildew preventing and treating leaf fertilizer to obtain liquid which is 1000-1500 times of the original weight to carry out spraying, so that the tests prove that the mixture which is 1000-1500 times of the original weight has remarkable inactivation function on the lettuce bremia, and has the effects of enhancing the photosynthesis of the lettuce leaves and increasing the leaf growth and increasing the hydrophily. The lettuce downy mildew preventing and treating leaf fertilizer is safe, environment-friendly and non-toxic, has trace element fertilizer and has the function of preventing and treating downy mildew.
