Novel winter plant protection system and use method thereof

Abstract

The invention discloses a novel winter plant protection system and a use method thereof. According to the technical scheme, the novel winter plant protection system is characterized by sequentially comprising a plastic protection layer, a thermal insulation layer, a pesticide storage layer and a bonding layer from outside to inside, wherein the pesticide storage layer comprises at least two layers of fabric, a solid pesticide is distributed between adjacent pieces of fabric, a plurality of fixing pieces are distributed on the pesticide storage layer, the solid pesticide is a fumigant solid insecticide, accordingly, the fumigant solid insecticide can effectively give out pesticide after being attached, the insect killing and dispelling effects are performed effectively, and the insect control effect of trunks is effectively improved. With the adoption of the solid pesticide, no vast water is produced during storage and use, pesticide effect loss is effectively avoided, dryness of the thermal insulation layer and the pesticide storage layer is effectively kept, the condition that the thermal insulation layer and the pesticide storage layer freeze due to outside low temperatures is avoided, and the thermal insulation effect is effectively improved.

Description

technical field [0001] The invention relates to the field of overwintering protection parts for winter plants, more specifically, it relates to a novel winter plant protection system and its application method. Background technique [0002] The winter in the north is cold and lasts for a long time, and many marginal tree species have poor cold resistance, and they are prone to physiological frost damage during the winter, and some trunks are cracked by frost, resulting in plant death. The late spring is cold for a long time, causing some branches and buds to germinate, and after the leaves are opened, they will suffer from freezing damage, branching, earing, etc. The traditional cold protection measures are to use newspapers and straw ropes, which have poor cold protection effect and are not beautiful. Both newspaper and straw rope are single-use and cause damage to the environment. Workers need to bind themselves when operating, which is cumbersome and time-consuming, and...

Problems solved by technology

[0004] In order to deal with the existing problems, a cold-proof and insect-resistant protective cover for trees (application number: 201120185029.3) is currently disclosed on the patent network, which mainly includes an inner layer, an outer layer, and an interlayer. Pesticides, but because the protective cover uses the way of immersion to store drugs, (1) the internal drugs are easy to flow away during storage, which greatly reduces the efficacy of the drugs; The protective cover is prone to mildew, which will easily cause the death of the tree trunk when used after mildew; (3), when in use, the agent is easy to flow vertically in the geotextile under the action of gravity, so that the agent directly flows into the soil, resulting in killing The insect effect is lost, and the soil structure is destroyed, causing environmental pollution; (4), because the geotextile is soaked in the chemical, the geotextile is relatively moist, and the insulation layer is also moistened by the diffusion of the liquid. When the temperature is too low in winter, As a result, icing occurs inside, so that the medicine cannot flow, and the insulation layer also loses its insulation effect
