The invention discloses a special organic fertilizer for large hawthorn and a preparation method thereof. The special organic fertilizer is characterized by being mainly prepared from the following raw materials and components in parts by weight: 300 parts of dry silkworm excrement, 10-20 parts of peanut meal, 20-40 parts of peanut shell middlings, 0.5-1.5 parts of microbial agent, 4-8 parts of tea seed shell carbon granule, 20-40 parts of sugarcane ash and 1-6 parts of lime powder. The preparation method is continuous in production and is reduced in fertilizer granulation and liquid drying procedures; the preparation method is simple and easy to operate, good in quality of the organic fertilizer and less in operation of labor, and is reduced in production cost; the special organic fertilizer is reasonable in nutrient structure, has an effect of a controlled release fertilizer, and has the functions of holding water and improving soil, is reduced in fertilizer loss and increased in fertilizer utilization rate, is capable of meeting the nutrient requirement of a large hawthorn tree, and is capable of increasing the yield and improving the quality; and the hawthorn can be freshly eaten, and is good in taste, less in astringent, long in storage period, and better in economic benefit, ecological benefit and social benefit.

The invention discloses a duplication dynamics automatic adjustment structure assembly of a stylus printer. The duplication dynamics automatic adjustment structure assembly of the stylus printer comprises a support and a paper-thickness regulating shaft of an eccentric shaft, wherein one end of the paper-thickness penetrates through the support, and then a paper-thickness slection lever is fixedly installed at a tail end of the paper-thickness regulating shaft. The paper-thickness selection lever is in a sector structure, and a surface of the selection lever is divided into an inner sector shape and an outer sector shape. File position teeth are arranged on one end surface of the inner sector shape along diameter direction of the inner sector. Blocking needles locked in the file position teeth are arranged on the support. A U-shaped photo-electricity sensor is installed on the end surface of the support nearby the paper-thickness selection lever. Blocking slices capable of sheltering beams of the U-shaped photo-electricity sensor are arranged on the paper-thickness selection lever. A duplication dynamics state of the automatic adjustment stylus printer is capable of abandoning a duplication dynamics adjustment manner of manually regulating the duplication dynamics through a panel press button in the traditional technology. The duplication dynamics automatic adjustment structure assembly of the stylus printer is simple in structure, reasonable and compact, saving in bill material and high in printing efficiency.
