Lasting-fertilizer-effect and low-cost sustained-release fertilizer special for potatoes

Abstract

The invention discloses a lasting-fertilizer-effect and low-cost sustained-release fertilizer special for potatoes. The lasting-fertilizer-effect and low-cost sustained-release fertilizer special for the potatoes comprises the following raw materials in parts by weight: 10 to 20 parts of molasses powder, 50 to 90 parts of rotten chicken manure, 1 to 2 parts of zinc ammonium phosphate, 2 to 4 parts of manganese ammonium phosphate, 1 to 3 parts of calcium hydrophosphate, 1 to 2 parts of coated ferric citrate, 20 to 40 parts of animal bone powder, 35 to 50 parts of urea, 12 to 20 parts of plant ash, 30 to 55 parts of potassium sulfate, 0.02 to 0.04 part of bacillus licheniformis, 0.008 to 0.012 part of diethyl aminoethyl hexanoate, 0.005 to 0.009 part of paenibacillus polymyxa, 6 to 12 parts of lignin, 6 to 18 parts of China fir charcoal and 3 to 7 parts of aedelforsite. The lasting-fertilizer-effect and low-cost sustained-release fertilizer special for the potatoes can be applied once without top application, has a significant and durable fertilizer effect, provides nutrient elements required by growth of the potatoes, has a good sustained-release effect, can improve the soil structure and enables the yield of the potatoes to be high.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special slow-release fertilizer for potatoes with low fertilizer efficiency and low cost. Background technique [0002] Potatoes are named for their resemblance to horse bells. This name was first seen in "Songxi County Chronicle Shihuo" in the Kangxi period. Northeast China and Hebei are called potatoes, North China is called yam eggs, Northwest and Lianghu areas are called yams, Jiangsu and Zhejiang are called yams or yams, Guangdong is called yams, eastern Guangdong is called Dutch yams, and eastern Fujian is called yams. Sweet potatoes are called "potatoes" in Northwest Hubei. Potatoes have a high yield and play an important role in production. Currently commercially available potato fertilizers are poorly targeted and cannot give full play to the yield-increasing effect of fertilizers, and need to be topdressed many times, which is time-consuming and labor-intensive,...

Problems solved by technology

Potato fertilizers currently available in the market are poorly targeted and cannot give full play to the yield-increasing effect of fertilizers, and need to be topdressed many times, which is time-consuming and labor-intensive, increasing production costs
