A crusher includes a blade assembly and a drive assembly. The blade assembly includes a first blade and a second blade. The drive assembly is respectively connected with the first blade and the second blade, and is configured to drive the first blade and the second blade to rotate. The first blade is configured to disperse and perform primary cutting of the materials. The second blade is configured to perform secondary cutting of the materials. The first blade makes the materials fully disperse, so that the second blade can fully cut the materials. In addition, the first blade initially cuts the materials, so that the formed fragments can achieve a better fertilization effect.

Disclosed is a method of synthesizing 1,2,4-triazole-3-thione compounds and intermediates thereof. The method includes reacting a hydrazine with glyoxylic acid to form a hydrazono acetic acid intermediate followed by reacting the latter with thiocyanate to obtain the 1,2,4-triazole-3-thione compound. The raw materials involved in the present method are readily available, and the reaction is very specific in terms of regioselectivity, resulting in minimum by-product and high product yield. There are neither specific requirements for special equipment nor special operations such as high vacuum, high temperature, anhydrous and oxygen-free manipulations. The process is simple and generates minimum wastes, suitable for industrial production.

Disclosed are a method of synthesizing prothioconazole and optically active isomers thereof and intermediates. The method includes reacting hydrazine with glyoxylic acid to produce a hydrazono acetic acid as an intermediate, and then reacting the intermediate with thiocyanate to produce the target product prothioconazole. The present method is very specific in terms of regioselectivity, resulting in minimum byproducts and a high product yield. The present method does not require special equipment, nor anhydrous or oxygen-free manipulations. The process is simple and generates minimum wastes, suitable for industrial production.
