Description

Reflective film laying device for fruit trees

Technical Field

The invention relates to the technical field of fruit tree cultivation and plant protection, in particular to a reflective film laying device for fruit trees.

Background

The reflective film is arranged in the orchard, so that the illumination conditions of the whole orchard, particularly the lower part of a crown and an inner bore are improved through the reflection of the reflective film to sunlight, fruits in the parts, particularly parts (such as hollow parts) where the fruits are not easy to color, are fully colored, full red fruits are increased, and the appearance quality of the fruits is improved.

The diaphorina citri belongs to the family of hemiptera psyllidae and is an important pest on Rutaceae plants such as citrus, lemon, clausena lansium, Murraya paniculata and the like. The diaphorina citri absorbs harm, adults are scattered on leaves and young buds to absorb the diaphorina citri, nymphs are clustered on young shoots, young buds and new leaves to damage, the young shoots and the young buds are yellowed, withered and withered, the new leaves are easy to fall off due to distortion and deformity, and the growth of plants is seriously influenced. White honeydew secreted by nymphs in the feeding process is attached to the surface of plant leaves to influence plant light and action and simultaneously cause sooty mold. Compared with the direct feeding hazard, the diaphorina citri is used as an important transmission medium of the citrus yellow dragon pathogen, and the loss caused by the citrus industry is huge. The diaphorina citri has a developed compound eye structure and strong visual ability, has higher dependence on vision when flying to land and harm plants, and the reflective membrane is also used for repelling small flying insects on the plants, such as aphids, thrips, psyllids and the like, and preventing the insects from flying to the plants to eat and harm the plants.

Among the prior art, thereby the reflective membrane causes rainwater to deposit easily when ground is laid and makes the surface oxidation of reflective membrane, the reflective membrane of laying in addition needs to use soil or fragment of brick to push down, and soil mixes with the rainwater easily on the reflective membrane, influence the reflection of light effect of reflective membrane, use the fragment of brick to carry again inconveniently, and to the fruit tree that the pest has appeared, although ground reflective membrane can drive partial larva and drop, the larva still can climb to the fruit tree from the root of a tree, look for the place that light is weak and continue to endanger the fruit tree, for this reason, we propose a reflective membrane laying device for the fruit tree that can ponding insect pest control.
