Abstract

The invention discloses a medicinal fertilizer with concentrated biogas slurry as a carrier coupled with allothigene to prevent and treat sweet potato ditylenchus destructors. The medicinal fertilizer comprises the following components in parts by weight: one or two allothigenes, 0.1-3% of organic silicon, 3-10% of aids and the balance of concentrated biogas slurry, wherein each allothigene accounts for 0.1-10%. As the biogas slurry is coupled with the allothigenes, the medicinal fertilizer has remarkable synergic effects in preventing and treating the sweet potato ditylenchus destructors, is capable of greatly shortening the lethal time of nematode, meanwhile is capable of improving soil structures and fertility situations of agricultural fields, is capable of increasing single yield of crops, and has dual effects of killing insects and improving fertility.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a medicinal fertilizer for controlling D. destructor of sweet potato by using concentrated biogas slurry as a carrier to couple exogenous substances. Background technique [0002] Sweet potato rot nematode ( Ditylenchus destructor ) is a migratory endoparasitic nematode that primarily affects the underground parts of plants (nodules, stolons, bulbs, rhizomes and tubers). In my country, it mainly harms sweet potato, is an important nematode disease in agriculture, and is also a quarantine dangerous nematode in my country and other countries and regions. In recent years, due to improper introduction of sweet potato, the spread of sweet potato stem nematode disease has spread. Generally, the diseased field reduces production by 20% to 50%, and the severely diseased field even loses production. At present, exogenous substances are mainly used to control D. destructor sweet p...
