Problems solved by technology

[0003] At present, my country mainly uses chemical fertilizers in agricultural fertilizers to increase production. Chemical fertilizers are also called inorganic fertilizers. They have the characteristics of fast fertilizer efficiency and strong fertilizer, but the persistent damage to the soil is also obvious. It will not only Weaken the productivity of crops, aggravate the pollution of the environment, and the nutrients needed by the human body will be greatly reduced in the crops grown by using chemical fertilizers, which will endanger the health of the Chinese people, and even cause poisoning or cancer in severe cases

Embodiment 1

[0020] Weigh 1 portion of fresh Polygonum cuspidatum, purify and heat-sterilize it in advance, mash it manually or with a machine, put it into a fermentation tank with a temperature between 42°C and 60°C, and cover it with plastic The film completely seals the fermentation tank, fermented and acidified for 3-7 days, and the oxalic acid concentration of Polygonum cuspidatum after fermentation must reach 60% to 75%, so that it is easy to decompose rock phosphate; The fineness of powder is required to be 90%~95% of mineral powder passing through 100 mesh sieve), weigh 90-120 parts and add it into the fermentation tank, mix it with Polygonum cuspidatum oxalic acid, stir evenly, after covering with plastic film, continue to heat at 42℃~ Ferment at a temperature of 60°C for 13-17 days until it is completely decomposed; finally, put the semi-finished product in the fermentation tank to dry in the sun or dry it with a dryer until it becomes powdery, then weigh it and pack it into a bag...

Abstract

The invention discloses an organic phosphatic fertilizer and a preparation method thereof. The organic phosphatic fertilizer is characterized in that ground phosphate rock is taken as the raw material of the phosphatic fertilizer and polygonum cuspidatum is taken as the raw material of an organic acid, and the weight part ratio of the two raw materials is (90-120): 1. The preparation method comprises the following steps: taking fresh polygonum cuspidatum, mashing the polygonum cuspidatum after cleaning and heating sterilization and putting the mashed polygonum cuspidatum into a fermentation tank at a temperature within the range of 42 to 60 DEG C; completely sealing the fermentation tank by use of plastic thin film and fermenting and acidifying for 3-7 days; next, adding the ground phosphate rock to the fermentation tank, uniformly mixing and stirring with the polygonum cuspidatum acid, and further fermenting at a high temperature ranging from 42 to 60 DEG C for 13-17 days until complete decomposition; finally, drying in the sun or drying until powder is obtained, and weighing, bagging and packaging. According to the organic phosphatic fertilizer, the fermented polygonum cuspidatum is adopted to replace sulfuric acid as the source of the acid substance of phosphatic fertilizer production for the first time; the natural plant is taken as the raw material, no chemical synthetic substance is used and added in the production process, the equipment investment and loss are low, the process is simple and no waste is discharged, and therefore, the organic phosphatic fertilizer is suitable for the production of organic agriculture and green agriculture.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to an organic phosphate fertilizer with simple process and without adding any chemical substances and a preparation method thereof. Background technique [0002] Phosphate fertilizer is a chemical fertilizer containing the crop nutrient phosphorus produced from phosphate rock. Phosphorus is a component of cell protoplasm in plants and plays an important role in cell growth and proliferation; it also participates in photosynthesis in plant life, utilization of sugar and starch, and energy transfer. In addition, phosphorus fertilizer can also promote the growth of the root system of plants at the seedling stage and make the plants mature early; when the plants bear fruit, a large amount of phosphorus is transferred to the grains, making the grains plump. Therefore, phosphorus fertilizer is one of the indispensable fertilizers in agricultural production. [0003] At present, my c...
