Technical method for controlling soil borne diseases of ginger

Abstract

The invention provides a technical method for controlling soil borne diseases of ginger. A farm chemical adopted by the method is a sodium dichloroisocyanurate soluble powder, wherein the available chlorine content of the sodium dichloroisocyanurate soluble powder is 60%. The method includes the following steps: a step of seed drying and disinfection. The step of seed drying and disinfection includes: diluting the 60% sodium dichloroisocyanurate soluble powder with water so as to obtain a 500-600 folds solution, and evenly spraying surfaces of ginger to be dried. The 60% sodium dichloroisocyanurate soluble powder can kill bacteria, stimulate the activity of various enzymes in crops, can enhance photosynthesis of leaves of the crops, make the leaves of the crops green, make crop plants strong and health, and can increase the yield; and the 60% sodium dichloroisocyanurate soluble powder can prevent the ginger soil borne diseases such as a bacterial wilt disease, a stalk rot disease, and a southern blight disease, is good in treat effect, is powerful in sterilizing, can treat many diseases, and will not cause resistance to farm chemicals and pesticide residues.

Description

Technical field [0001] The invention relates to a technical method for preventing and controlling soil-borne diseases of ginger, belonging to the field of crop disease prevention and control. Background technique [0002] Ginger is a perennial root herb of the ginger family Zingiberaceae. It is cultivated as an annual crop in my country and is one of the important special vegetables in my country. [0003] Ginger is originally produced in India-Malay subtropical rainy forest area. It has a long history of cultivation in my country. There are records of ginger planting as early as the spring and autumn period. At present, it is cultivated in all provinces south of the Yangtze River in my country, and cultivated in Shandong, Henan, Shaanxi and Liaoning to the north of the Yangtze River. In terms of county planting scale, Anqiu, Shandong has the largest planting area, reaching more than 200,000 mu, making it the main ginger producing area in Shandong and even the whole country. The 6...

AI Technical Summary

Problems solved by technology

[0007] Second, improper fertilization

[0008] Third, nematode infestation

[0017] 1. The method for preventing and treating ginger diseases in the prior art is due to excessive, large-scale, and compound use of pesticides, resulting in excessive pesticide residues, increased drug resistance of bacteria, serious non-point source pollution, reduced product quality, and reduced commerciality;

[0018] 2. The methods for preventing and treating ginger diseases in the prior art have not formed a complete set of prevention and treatment schemes from planting to harvest; disorderly use of drugs, disorderly use of drugs, and excessive application of pesticides have occurred, resulting in the application of pesticides and money. The ginger is still dead in a large area;

[0019] 3. The existing technical methods for the prevention and treatment of ginger soil-borne diseases are costly;

[0020] 4. In the prior art, there are many varieties of pesticides used to prevent and control ginger diseases, and the range of sterilization among varieties is narrow. Mixed application of various agents is required. If the disease is found and applied again, the appropriate period for prevention and control is often missed;

[0021] 5. In the prior art, especially soil fumigation and disinfection technology pollutes the environment; soil fumigant is a volatile organic compound. Field experiments show that the distribution of soil fumigant into the atmosphere is very obvious, accounting for 20%-90% of the total application amount , the fumigant emitted into the atmosphere will cause harm to the human body and the environment;

[0022] 6. It is difficult to prevent and control ginger soil-borne diseases by adopting existing technologies;

[0024] 8. Soil fumigation and disinfection technology requires professionals to use special equipment to apply it into the soil; because soil fumigant (chloropicrin) is a highly toxic pesticide and dangerous chemical, it is one of the products specially managed by the national public security and security inspection departments. Pesticide applicators need to undergo professional training, wear protective equipment, use professional equipment, and stand in the limelight to apply pesticides, which is troublesome to apply;
