Embodiment 1

[0023] Collect tobacco stalks, air dry the tobacco stalks naturally to reduce the water content to less than 16%, crush them into 2-10mm sizes, then put the tobacco stalks into a biomass carbonization furnace, and decompose them by anoxic dry distillation under sub-high temperature conditions Biomass granular charcoal is produced by the process. After the processed biomass granular charcoal is cooled, it is taken out and crushed through a 40-60 mesh sieve to obtain tobacco stalk biochar powder: put the obtained tobacco stalk biochar powder into a plastic bag and seal it , stored in a desiccator for later use.

[0024] The tobacco stalk biomass charcoal powder was subjected to a toxicity test. Put 80 apple snails per square meter in a plastic basin. The age and size of the golden apple snails are not limited. The water temperature is 25-30°C. It was observed at different times that after adding 39.8 g / ㎡ of tobacco stalk biochar powder, the mortality rate of apple snails reache...

Embodiment 2

[0026] Collect tobacco stalks, air dry the tobacco stalks naturally to reduce the water content to less than 16%, crush them into 2-10mm sizes, then put the tobacco stalks into a biomass carbonization furnace, and decompose them by anoxic dry distillation under sub-high temperature conditions Biomass granular charcoal is produced by the process. After the processed biomass granular charcoal is cooled, it is taken out and crushed through a 40-60 mesh sieve to obtain tobacco stalk biochar powder: put the obtained tobacco stalk biochar powder into a plastic bag and seal it , stored in a desiccator for later use.

[0027] Since adult apple snails are the most harmful and have strong destructive ability when rice is transplanted, and the individual gonads are mature and have strong fecundity, the toxicity of the tobacco stalk biomass charcoal powder to adult apple snails was tested in this example. Put 80 / ㎡ adult apple snails in a plastic basin (the weight of the snail is 6.5 g / abo...

Abstract

The invention belongs to the technical field of comprehensive utilization of agricultural wastes and discloses a method for preparing biomass particle carbon to kill apple snails by tobacco stalks. The method includes naturally air-drying tobacco stalks to reduce water content to less than 16%, and crushing to 2-10mm in size; placing the tobacco stalks into a charcoal furnace, and producing biomass particle carbon at sub-high-temperature by anaerobic destructive distillation decomposition process; cooling processed biomass particle carbon to take out and crush to go through a 40-60mesh screen to obtain tobacco stalk biomass carbon powder; and adding the tobacco stalk biomass carbon powder according to amount of 72.8g / m(2)-98.3g / m(2) to water, and completely killing apple snails after three days. Proper amount of biomass carbon powder prepared by the tobacco stalks is added to water to directly kill apple snails. The method is simple and easy to implement, evidently effective and low in cost, and reutilization of waste resources is achieved.

Description

[0001] technical field [0002] The invention belongs to the technical field of agricultural waste recycling, and in particular relates to a method for killing apple snails, an alien invasive mollusk in South China, by using tobacco stalks to prepare biomass granular carbon. Background technique [0003] Apple snail ( Amazonian smail ) also known as the big bottle snail, amphibious freshwater shellfish mollusk, belongs to the mollusc phylum, gastropoda, mesogastropoda, bottle snail family; the shell is approximately disc-shaped, generally has 6 spiral layers; it likes to inhabit slow-flowing rivers and shade Humid and ventilated ditches, streams and paddy fields, etc.; apple snails are dangerous and harmful invasive organisms that have attracted much attention in the world in recent years. The growth of aquatic crops has amazing fecundity and extremely fast growth speed. Although it is an aquatic species, it can be buried in moist soil for 6-8 months during the dry season, an...
