Abstract

The invention discloses a biological compound fertilizer for preventing potato late blight. The biological compound fertilizer is prepared from, by weight, 40-45% of organic fertilizer, 10-13.5% of urea, 5-6.5% of monoammonium phosphate, 22-26.5% of potassium sulfate, 1-2% of borax, 1-1.2% of copper sulfate, 1-1.7% of chelated zinc, 0.8-0.9% of chelated iron, 0.1-0.3% of amino-oligosaccharin, 0.5-2% of salicylic acid, 0.1-0.15% of rhodotorula sp, 0.1-0.2% of xenorhabdus nematophila and the balance auxiliaries. A preparation method of the organic fertilizer includes the following steps that straw and traditional Chinese medicine residues are aired and smashed, then duck manure and urea are added and evenly mixed, the water content is adjusted to 50-60 wt%, and a material a is obtained; cellulase, straw fermenting inoculant and brown sugar are added into water and evenly mixed and inoculated into the material a for fermentation, pile turning and ventilation are carried out in the fermentation process, fermentation temperature is 30-50 DEG C, curing is conducted, and the organic fertilizer is obtained after drying.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a biological compound fertilizer for preventing and treating potato late blight. Background technique [0002] Potatoes are rich in nutrients and high in yield. They are the fourth largest food crop in the world. my country also launched the potato staple food strategy in 2015 and has become the country with the largest total potato production in the world. However, potato late blight is widespread, and its damage has surpassed wheat rust and rice blast, seriously restricting and affecting the yield and quality of potato. Long-term chemical pesticide control also makes late blight resistant and affects the environment. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a biological compound fertilizer for preventing and controlling potato late blight, which can effectively prevent and con...
