Practical method for growing pesticide-free greenhouse vegetables

Abstract

The invention discloses a practical method for growing pesticide-free greenhouse vegetables, which is implemented by the following: 1, a step of optimizing and disinfecting seeds, which is to fume the seeds for 20 to 30 minutes with powder incense prepared from ground Chinese medicines including cedar, nardostachys chinensis batal and dipterocarpus retusus, and immerse the seeds in an oxidation potential water and ozone mixed solution with a pH value of less than 2.7 and an oxidation-reduction potential (ORP) more than 1,100 mv for disinfection; 2, a step of optimizing soil, dispelling insects and disinfecting, which is to regulate the pH value of the soil to a favorable pH value of the crops by spraying acid and alkaline potential water onto the soil and to dispel insects in soil by using mixture of sophora flavescens and pinellia ternata powder and ozone water; 3, a step of sterilizing and disinfecting environment in a greenhouse, which is to disinfect the wall of the greenhouse and the pavement and air in the greenhouse every other two days by using incense and ozone and oxidation potential water mixed solution; 4, a step of sterilizing surface of plants, which is to prepare the acid and alkali oxidization potential water mixed solution containing Chinese medicines by using mother liquor of decoction of the Chinese medicines including the tuber of stemona, sophora flavescens and fructus cnidii, spray the mixed solution on the surface of the plants for sterilization every other 6 days; and 5, a step of sterilizing roots of plants, which is to sterilize the roots of plants by using ozone and biogas mixed nutritional solution. The method can effectively kill bacterial viruses, spoilage organisms and pests and can prevent and control disease pests in place of pesticides.

Description

technical field [0001] The invention relates to vegetable production technology, in particular to a practical method for producing shed vegetables without pesticides. Background technique [0002] At present, in the production process of greenhouse vegetables in rural areas of our country, the method of spraying pesticides is mostly used to prevent pests and diseases, so as to increase the production and income of greenhouse vegetables, but the residue of pesticides will have a great impact on food safety and people's living and health. Studies have shown that long-term accumulation and retention of pesticide residues in fruits and vegetables in the human body will cause chronic poisoning, which is more terrible than acute poisoning. Chronic poisoning will induce many chronic diseases. What is even more difficult to predict and prevent is the accumulation of pesticides in the human body. It will also be passed on to the next generation through pregnancy and breast-feeding, e...
