High-concentration ecological compound fertilizer, preparation method and application in agricultural and forestry production

Abstract

The invention discloses a high-concentration ecological compound fertilizer, a preparation method and application in agricultural and forestry production, belonging to the agricultural and forestry fields. The high-concentration ecological compound fertilizer takes semi-finished ecological compound fertilizer products as cores, wherein the semi-finished ecological compound fertilizer products are wrapped with organic enveloping liquid, plant probiotics, secondary element additives and trace element additives. Compared with the existing fertilizer, the high-concentration ecological compound fertilizer can provide various balanced nutrients to crops in a long term according to different nutrient demands of the crops at different growth stages, special sensitive secondary and trace elements are added for different crops, nutrient deficiency symptoms of plants, vegetables and the like are prevented from occurring and the quality and the taste of the crops can be improved at the same time. The high-concentration ecological compound fertilizer has the advantages that the water and fertilizer absorbing capacity of the plants is improved, the crops grow robustly, the drought resistance is improved, the yield is increased and the quality is improved; and the decomposing speed of pesticide is reduced, the efficacy of the pesticide is increased, the used amount of the pesticide is reduced, the residue of the pesticide is reduced, the development of green food is facilitated, the safety of agricultural products is improved and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a high-concentration ecological compound fertilizer and its preparation method and application in agricultural and 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, out of the 15 million tons (pure conversion) of phosphate fertilizer used in my country each year, 8 million tons (pure conversion)...

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
