Problems solved by technology

Perfume lemon trees grow vigorously and have strong flowering. In order to ensure the fruit setting rate and nutrient distribution, the lemon trees must be pruned several times a year. Every orchard produces a large number of pruned and discarded leaves every year. The treatment method is generally to pile it up in the orchard and burn it after it dries up, which not only consumes time and space, but also pollutes the environment
All do not find that these perfume lemon leaves are rationally developed and utilized at home and abroad, resulting in a great waste of resources
Existing chemically synthesized anti-mosquito products have certain toxicity to the human body; existing plant essential oil anti-mosquito products have a single effect and only have a single mosquito repellent function, and the effect is not obvious
