Chemical-biological joint control fertilizer capable of reducing cadmium accumulation of vegetables and increasing yield of vegetables as well as preparation and application of chemical-biological joint control fertilizer

Abstract

The invention discloses a chemical-biological joint control fertilizer capable of reducing cadmium accumulation of vegetables and increasing the yield of the vegetables as well as preparation and application of the chemical-biological joint control fertilizer. The chemical-biological joint control fertilizer is in a solid granule shape, and sequentially comprises a urea-Nitrapyrin mixture positioned in the center of the granule, a coating film coated outside the urea-Nitrapyrin mixture and an embedding layer which is positioned outside the coating film and contains Amycolatopsis orientalis from inside to outside. The chemical-biological joint control fertilizer can efficiently reduce and control cadmium accumulation of crops in a long-acting manner, and can also increase the crop yield at the same time.

Description

technical field [0001] The invention relates to the field of safe utilization of cadmium-contaminated cultivated land, in particular to a chemical-biological joint control fertilizer and a preparation method thereof which can effectively reduce the accumulation of cadmium in vegetables and increase the yield of vegetables. Background technique [0002] Soil heavy metal cadmium pollution is one of the serious environmental pollution problems in my country. At present, methods such as directly replacing soil or using passivating agents are commonly used to remediate polluted soil, but these methods are expensive and difficult to popularize and apply. Although the soil remediation technology based on hyperaccumulative plants has economic and environmental advantages, the implementation period of this technology is long, which seriously restricts agricultural production. Respecting market principles and the interests and needs of relevant parties, it is imminent to develop tech...
