Problems solved by technology

Its black shank, viral disease and cutworm have a great impact on the vegetative growth and product appearance of potatoes, reducing the commodity value of potatoes
The culprit causing the above-mentioned soil-borne diseases is the germs hiding in the soil cultivation layer. They are distributed in different parts of the soil. As long as the host plants appear, these dormant germs will germinate and affect plant growth and attack by producing toxins. The root system of the plant enters the plant body and causes the disease or death of the plant. It is difficult to eliminate these germs in the soil with pesticide control. Although soil disinfection is a relatively good method, it is difficult to do it in actual production. The reason is that The diseased soil area is large and the amount is wide, the cost of comprehensive soil disinfection is high, the operation is difficult, and it is almost impossible
For the prevention and control of potato seed-borne soil-borne diseases, the plant protection policy of "prevention first, comprehensive prevention and control" should be implemented. When selecting pesticides, the method of soaking seeds is generally adopted, but the pesticides are easy to remain on potato seed blocks, which will cause poisoning to humans and animals.

Embodiment 1

[0016] Weigh 3.3kg of 2% kasugamycin wettable powder and 3.3kg of 30% DT wettable powder and mix them first, then add 1.9kg of 50% phoxim emulsion and 1.5kg of 30% chlorpyrifos emulsion, and stir again .

[0017] Sprinkle the mixed pesticide on the surface of 1000kg compost, and use a large compost turner to mix the pesticide and fertilizer evenly. Before mixing the fertilizer and pesticide, the pH in the compost should be less than 7.0, the moisture should be controlled at about 40%, and the temperature should not exceed 60°C. The mixing time should be after the compost has been turned 2 to 3 times, and the compost has been decomposed for 15 days. The product quality implements the national standard of organic fertilizer.

[0018] Combined with furrow digging and soil preparation, apply 700-1000 kg of potato fertilizer per mu, spread the fertilizer on the furrow surface, and mix well with the soil.

Embodiment 2

[0020] Weigh 2.5 kg of 2% kasugamycin wettable powder and 3.5 kg of 30% DT wettable powder and mix and stir first, then add 2 kg of 50% phoxim emulsion and 2 kg of 30% chlorpyrifos emulsion, and stir again.

[0021] Sprinkle the mixed pesticide on the surface of 1000kg compost, and use a large compost turner to mix the pesticide and fertilizer evenly. Before mixing the fertilizer and pesticide, the pH in the compost should be less than 7.0, the moisture should be controlled at about 40%, and the temperature should not exceed 60°C. The mixing time should be after the compost has been turned 2 to 3 times, and the compost has been decomposed for 15 days. The product quality implements the national standard of organic fertilizer.

[0022] Combined with furrow digging and soil preparation, apply 700-1000 kg of potato fertilizer per mu, spread the fertilizer on the furrow surface, and mix well with the soil.

Embodiment 3

[0024] Weigh 3.5 kg of 2% kasugamycin wettable powder and 3 kg of 30% DT wettable powder and mix them first, then add 2.5 kg of 50% phoxim emulsion and 1 kg of 30% chlorpyrifos emulsion, and stir again.

[0025] Sprinkle the mixed pesticide on the surface of 1000kg compost, and use a large compost turner to mix the pesticide and fertilizer evenly. Before mixing the fertilizer and pesticide, the pH in the compost should be less than 7.0, the moisture should be controlled at about 40%, and the temperature should not exceed 60°C. The mixing time should be after the compost has been turned 2 to 3 times, and the compost has been decomposed for 15 days. The product quality implements the national standard of organic fertilizer.

[0026] Combined with furrow digging and soil preparation, apply 700-1000 kg of potato fertilizer per mu, spread the fertilizer on the furrow surface, and mix well with the soil.

Abstract

The invention relates to a special medicated fertilizer for potatoes and a preparation method thereof. The medicated fertilizer is prepared by mixing organic fertilizer into a pesticide; the pesticide comprises the following components in parts by mass: 25-35 parts of 2% kasugamycin wettable powder agent, 25-35 parts of DT wettable powder agent, 15-25 parts of 50% phoxim emulsifying agent and 15-25 parts of chlorpyrifos emulsifying agent. As the fertilizer and the pesticide are organically combined together, the medicated fertilizer is more convenient to use. Due to the adoption of the special medicated fertilizer, underground pests such as potato black rot and cutworm and the like can be prevented obviously, and the rate of germination and commodity value of potatoes can be effectively improved, economic, social and ecological benefits are very obvious, and the application and popularization values are larger.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a special medicinal fertilizer for potatoes and a preparation method thereof. Background technique [0002] Potatoes are rich in starch and sugar, and have high nutritional value and commodity value. In recent years, with the large-scale planting of potatoes, the occurrence of pests and diseases has become increasingly serious. Its black shank, viral disease and cutworm have a great impact on the vegetative growth and product appearance of potatoes, reducing the commodity value of potatoes. The culprit causing the above-mentioned soil-borne diseases is the germs hiding in the soil cultivation layer. They are distributed in different parts of the soil. As long as the host plants appear, these dormant germs will germinate and affect plant growth and attack by producing toxins. The root system of the plant enters the plant body and causes the disease or death of the plant. I...
