Abstract

The invention relates to a lamina greening spraying agent and a preparation method thereof, and belongs to the technical field of agriculture and forestry insect prevention. The lamina greening spraying agent comprises the following components in percentage by weight: 1-3% of pyrethrin active compound, 8-10% of a silkworm excrement extractive, 65-80% of beer, 1-5% of demerara, 1-5% of soften flux and the blance of water. The preparation method comprises the following steps: preparing the silkworm excrement into silkworm excrement extractive; mixing the pyrethrin active compound and the silkworm excrement extractive uniformly; adding the soften flux and mixing the components uniformly to obtain a mixed agentia; mixing and dripping the beer and the water in the mixed agentia to obtain the lamina greening spraying agent. The lamina greening spraying agent can efficiently prevent insects, expel parasite, and enable plant lamina to be lustrous and shiny, plays the function of quickly and effectively removing insects on the plants infected by diseases and insect pests, is suitable for long-term use of household plants, can be sprayed on lamina or in soil during flower watering, has no bad odors, and can keep plants healthy and green in a long term.

Description

Technical field [0001] The invention relates to a spray for increasing green leaves and a preparation method thereof, belonging to the technical field of agriculture and forestry insect prevention. Background technique [0002] The indoor decoration of green plants is very pleasant. But when it grows insects, it is a headache, because it is impossible to apply toxic pesticides indoors. Normally, healthy plants will not grow insects, but due to improper management, the plants will carry insects or eggs. [0003] When a plant is infested with insects, it will be accompanied by yellowing or leaf discoloration, and sticky residues will remain on the leaves or stems, making the ornamental value of green plants rapidly decline. Usually, people isolate plants with insects first to prevent the insects from being brought to other plants, and then remove them. [0004] Common pests include aphids, mealy scale insects, red spiders, scale insects and so on. Aphids will deform, stick, curl or...
