Embodiment 1

[0008] The organic fertilizer for preventing potato scab is composed of the following materials, which are respectively by weight percentage: composting material 89.8%, agricultural superphosphate 5%, sulfur powder 4.5%, pentachloronitrobenzene powder 0.7%, composting material by It is fermented by composting chicken manure, and 40% powder of pentachloronitrobenzene is used.

[0009] according to figure 1 The flow chart of the manufacturing process is shown.

Embodiment 2

[0011] The organic fertilizer for preventing potato scab is composed of the following materials, which are respectively by weight percentage: composting material 88.5%, agricultural superphosphate 5%, sulfur powder 6%, pentachloronitrobenzene powder 0.5%, composting material by It is fermented by composting chicken manure, and 40% powder of pentachloronitrobenzene is used.

[0012] Process flow is identical with embodiment 1.

Embodiment 3

[0014] The organic fertilizer for preventing potato scab is composed of the following materials, which are respectively by weight percentage: 91% of composting materials, 5% of agricultural superphosphate, 3% of sulfur powder, 1% of pentachloronitrobenzene powder, and the composting materials are composed of It is fermented by composting chicken manure, and 40% powder of pentachloronitrobenzene is used.

[0015] Process flow is identical with embodiment 1.

[0016] The composted material fermented by chicken manure composting is slightly acidic, rich in fertilizer nutrients, and contains a large amount of bacillus and yeast. These beneficial microorganisms are attached to organic fertilizers, and multiply in large numbers in the soil under more suitable environmental conditions to form dominant beneficial microorganisms, which have a resistance to actinomycetes, the causative bacteria of potato scab. However, when composted materials were used alone, they had no effect on pre...

Abstract

The invention discloses an organic fertilizer for preventing potato scab, which consists of 88.5 to 91 percent of composting materials, 5 percent of agricultural superphosphate, 3 to 6 percent of sulfur powders, and 0.5 to 1 percent of pentachloronitrobenzene powders, wherein the composting materials is prepared by fermenting chicken manure composts. The organic fertilizer is an compost organic fertilizer, has more than or equal to 4 percent of the total nutrients of nitrogen, phosphorus and potassium and more than or equal to 30 percent of organic matter content, does not have side effects on soil and environment, can obviously promote the growth, the yield increasing, and the high quality of potatoes, and has good disease prevention effect which reaches more than 15 percent; besides, the potatoes have bright skin color and good luster.

Description

Technical field: [0001] The invention relates to a fertilizer, in particular to an organic fertilizer for preventing potato scab. Background technique: [0002] Potato scab damages potato tubers, and there are nearly round to amorphous corky scab-like light brown lesions or plaques on the surface of the tubers, and the texture is rough to the touch. Usually, although the lesion is limited to the cortex, the quality and yield of the damaged potato pieces can still be reduced, and the appearance of the diseased potato is unsightly, and the commodity grade is greatly reduced. The pathogen is actinomycetes, called Streptomyces scab. The pathogen survives the winter on the diseased potato or leaves it in the soil, and can live saprophyticly in the soil. The pathogen uses spores as the inoculum for initial invasion and re-invasion, spreads with the help of wind and rain or the activities of small insects, and invades from lenticels or wounds to cause disease. The suitable tempe...
