Embodiment 1

[0012] Lettuce was cultured in a hydroponic box in an incubator for 7 weeks. The setting conditions of the incubator were 25°C during the day, 15°C at night, 70% relative humidity, and 200Lx daytime light intensity.

[0013] The formula of the healthy and disease-preventing nutrient solution used for lettuce cultivation contains the following components in each liter of nutrient solution: (Ca(NO 3 ) 2 4H 2 O, 236 mg; KNO 3 , 404mg; (NH 4 ) 2 HPO 4 , 57 mg; MgSO 4 ·7H 2 O, 123mg; EDTA-2NaFe, 60mg; H 3 BO 3 , 2.86mg; MnSO 4 4H 2 O, 3.20 mg; ZnSO 4 ·7H 2 O, 0.22 mg; CuSO 4 ·5H 2 O, 0.16 mg; (NH 4 )6Mo7O 24 4H 2 O, 0.02 mg.

[0014] The preparation method of the culture solution is to weigh the compounds of different components according to the formula dosage, and put them one by one into the bucket that has been connected with water in advance. Every time a compound is added, it must be fully stirred evenly before adding the second substance, until all are added...

Embodiment 2

[0016] CuSO per liter of lettuce health and disease prevention culture medium 4 ·5H 2 O, ZnSO 4 ·7H 2 O, EDTA-2NaFe, MnSO 4 4H 2 The contents of O are 0.15 mg, 0.20 mg, 55 mg and 3.00 mg respectively, and the composition, content, preparation method and lettuce cultivation conditions of the rest of the nutrient solution are the same as in Example 1.

Embodiment 3

[0018] CuSO per liter of lettuce health and disease prevention culture medium 4 ·5H 2 O, ZnSO 4 ·7H 2 O, EDTA-2NaFe, MnSO 4 4H 2 The contents of O are 0.18 mg, 0.25 mg, 65 mg and 3.30 mg respectively, and the composition, content, preparation method and lettuce cultivation steps of the rest of the nutrient solution are the same as in Example 1.

[0019] By superoxide anion (O 2. - ) and hydrogen peroxide (H 2 o 2 ) etc. active oxygen and malondialdehyde (MDA) content are measured and calculate its mean value (results are shown in the table below) as can be seen, in embodiment 1, O 2. - 、H 2 o 2 and MDA content are all lower than Examples 2 and 3, illustrating that compared with Examples 2 and 3, Example 1 has the best antioxidant and disease resistance, and is a group of formulas with the best fitness and disease prevention capabilities.

Abstract

The invention relates to a lettuce culture solution for health and disease prevention. Each liter of the culture solution contains: CuSO4 5H2O, 0.15-0.18 mg; ZnSO4 7H2O, 0.20-0.25 mg; EDTA-2NaFe, 55-65 mg; MnSO4 · 4H2O, 3.00‑3.30 mg. It is used in the laboratory research and hydroponic production of lettuce, and its disease resistance effect is obvious. Compared with the control, the disease index of gray mold of lettuce has dropped by 34.2%. Cultivate ecological products.

Description

technical field [0001] The invention relates to plant hydroponic technology, in particular to a lettuce culture solution. technical background [0002] For a long time, my country has mainly used chemical pesticides in the prevention and control of plant diseases. When a disease occurs, a large amount of pesticides are used. This method not only affects the effect of disease prevention, but also chemical pesticide residues have brought about increasingly serious problems such as food safety and ecological environment damage. . Nowadays, people are more and more aware of the significance of green ecological planting in the present and future, and hope to adopt an environmentally friendly method to fundamentally reduce the occurrence of diseases and insect pests, and create a healthy and harmonious ecological environment for human beings. [0003] Most of the existing lettuce culture solution formulations are developed from the perspective of meeting the basic nutritional requ...
