Environmental friendly fertilizer for lotus root growth and preparation method thereof

Abstract

The invention discloses environmental friendly fertilizer for lotus root growth and a preparation method thereof. The fertilizer comprises livestock and poultry manure, plant straws, wheat bran, chaff, plant ash, river bottom silt, attapulgite, activated carbon, humus, a fertilizer additive and a microbial agent. The preparation method comprises extracting the fertilizer additive, dispersing the extracted fertilizer additive on attapulgite, putting the above components into a fermentation tank, carrying out fermentation and then carrying out drying. The environmental friendly fertilizer is used for lotus root growth, replaces traditional chemical fertilizer, provides rich nutrients for crops, has effects of preventing and controlling plant diseases and insect pests, effectively preventing lotus root damage caused by insect pests in growth and greatly improving lotus root quality and has a good application value.

Problems solved by technology

[0002] At present, food safety accidents occur frequently. Farmers may also have toxic and harmful substances on the polluted land according to conventional planting methods. For example, a large number of lotus roots have recently been detected to be toxic and harmful and their metals exceed the standard, and the heavy metals in the soil exceed the standard. is its main cause

In addition, due to the long-term use of pesticides and chemical fertilizers, the content of artificial organic pollutants in the soil is getting higher and higher, and the phenomenon of agricultural environmental pollution and ecological imbalance in my country is becoming more and more serious. The yield and quality of crops are seriously affected, which in turn threatens the survival of human beings. The environment, the pollution of lotus root caused by it, the quality and safety of lotus root have attracted more and more people's attention, and have become the bottleneck restricting the sustainable and efficient development of lotus root production in the new stage

[0003] At present, lotus root fertilizers in my country, including fertilizers for other crops, are mostly inorganic fertilizers. Chemical fertilizers do not contain organic matter and humus, which destroys the soil aggregate structure, lowers the utilization rate of chemical fertilizers, and reduces the yield and quality of lotus roots. Harmful to human health, causing a large number of deaths of beneficial bacteria and earthworms in the soil, polluting rivers and soil

However, traditional organic fertilizer products cannot better solve various pollution problems
