Problems solved by technology

At the same time, adjustments are being made in terms of agricultural production technology, such as soil disinfection before planting in facility agriculture, seedling treatment for seedlings, base fertilizer and scientific formula and use of base pesticides, root irrigation, flushing, and foliar spraying. Multiple processing links increase production costs and labor costs, while the use of some pesticides exacerbates soil deterioration and brings hidden dangers to the safety of agricultural products

Abstract

The invention relates to a novel composite fertilizer which comprises the most important compositions as follows: seaweed extract, carapace amine oligosaccharide and a microbic living bactericide. The compositions have respective unique effects and are mutually facilitated, and multiple compositions such as humic acid, microelements, nitrogen phosphorus and potassium nutrient contents are added into the compositions and matched with the compositions flexibly to be prepared into liquid, powder and particles according to the requirements for product modality and target effects. When in use, the novel bio-fertilizer can be used as base fertilizer, water flush fertilizer, and leaf fertilizer; the product has the main effects of eliminating continuous-cropping obstacles and reducing dead seedlings and dead trees.

Description

technical field [0001] The invention relates to a novel biological compound fertilizer, which belongs to the fields of agricultural biotechnology and fertilizer industry. Specifically, it is a functional fertilizer related to reducing continuous cropping obstacles, seedling diseases caused by soil-borne diseases and preventing dead seedlings in the stage of crop seedling raising and after crop transplanting. Background technique [0002] In the 1960s, China's agricultural production began to use a large amount of chemical fertilizers. Since then, China's agricultural production has changed from green manure and farmyard manure to chemical fertilizers. The use of chemical fertilizers has gone through three stages: urea, diammonium and ternary compound fertilizers. Due to the quick-acting and yield-increasing properties of chemical fertilizers, they have been recognized by agricultural producers. The use of chemical fertilizers has brought about a rapid increase in crop produc...
