Abstract

The pollution-less fertilizer special for mustard tuber consists of urea, ammonium phosphate, potassium sulfate, magnesium sulfate, ammonium molybdate, boric acid, rape seed cake dreg, chicken excrement and zeolite. During the preparation, rape seed cake dreg and chicken excrement are processed to become harmless and effective before mixing with other components. The fertilizer contains various macro and micro elements essential for mustard tuber to grow.

Description

technical field [0001] The invention relates to the technical field of new agricultural fertilizers, in particular to a special fertilizer for pollution-free mustard mustard and a manufacturing method thereof. Background technique [0002] Mustard mustard (scientific name stem mustard) is an important processed stem vegetable in my country. Mustard mustard in my country has a long history of development, long cultivation time, large planting area, high-quality and delicious processed products, and good economic benefits. It is famous at home and abroad as "Fuling mustard mustard" in Chongqing. For a long time, the single application of chemical nitrogen and phosphorus fertilizers in mustard cultivation in order to achieve high yields has been common. Potassium fertilizers are rarely used, and the pollution-free fertilizers are not paid attention to. This has obviously affected the cultivation standardization of this traditional high-quality agricultural product and the high-...
