Ecological fertilizer, preparation method, and application of ecological fertilizer in agricultural or forestry production

Abstract

The present invention discloses an ecological fertilizer, a preparation method of the ecological fertilizer, and an application of the ecological fertilizer in agricultural or forestry production, and belongs to the fields of agriculture and forestry. According to the present invention, the ecological fertilizer adopts raw fertilizer as the core, an organic coating liquid, plant probiotics, medium element additives and microelement additives are coated on the outer of the core. Compared to the prior art, with the ecological fertilizer provided by the present invention, according to different nutrient requirements of crops in different growth stages, a lot of nutrients can be long-acting and balancedly provided for the crops, the sensitive medium elements and the microelements are added to the special products of different crops, and the generations of the nutritional deficiency symptoms of plants, vegetables and other crops can be controlled.

Description

technical field [0001] The invention relates to an ecological fertilizer, its preparation method and its application in agricultural or forestry production. Background technique [0002] my country has about 1.826 billion mu of arable land, but the per capita is less than 1.35 mu, and the existing arable land is constantly being occupied and reduced. Improving the output rate of limited land resources is the core issue of building modern agriculture. As we all know, due to volatilization, leaching, runoff, soil metal ion confinement and other reasons, the utilization rate of single application of chemical fertilizers is very low, and most of the effective nutrients are lost. The low utilization rate of fertilizer directly leads to the increase of agricultural cost and environmental pollution. According to statistics, among the 35 million tons and 15 million tons of nitrogen fertilizer and phosphate fertilizer applied in my country each year (both purely converted), 24 mill...

Problems solved by technology

However, due to the low utilization rate of chemical fertilizers in my country, especially nitrogen and phosphorus fertilizers, the annual loss rate of farmland nitrogen fertilizer is 33.3% to 73.6%, and the average total loss rate is about 60%; the loss rate of phosphorus fertilizer is 30.4% to 75.6%, and the average total loss rate is The loss rate is around 55%

On the other hand, due to the unreasonable excessive application of chemical fertilizers, it has caused negative impacts on crops, soil, water bodies and the atmosphere, such as soil compaction, the decline in fertility levels has no stamina, the economic benefits of fertilization have declined, and the quality of agricultural products has decreased—the so-called " Melons are not fragrant, fruits are not sweet, and vegetables are tasteless”

The nitrification of ammonia in nitrogen fertilizer increases the content of nitrate and nitrite in the water body, resulting in excessive nitrate and nitrite content in agricultural products, especially vegetables, posing a threat to human health
