Description

Technical Field

[0001] This invention relates to the field of agricultural facilities technology, and in particular to a hail protection device for apple orchards. Background Technology

[0002] In recent years, hail has occurred frequently in some areas, and the trend is gradually worsening, with the scope and probability increasing. This has caused serious losses or even crop failures for fruit growers. The peak hail season is around mid-April in late spring, which coincides with the initial flowering stage of apple trees. Hail at this time will knock off the open petals, significantly impacting fruit set. July and August are also peak hail seasons, when apple trees are in the early fruit development stage. Hail will directly damage and knock off the young fruit, causing the fruit surface to become pitted and riddled with holes, making it susceptible to disease infection and affecting the appearance and internal quality of the fruit. At the same time, it will also damage the leaves and new shoots, affecting the tree's photosynthesis and flower bud differentiation. In severe cases, it will damage the bark, causing secondary budding, leading to tree decline, affecting the following year's growth and fruiting, and causing a large-scale outbreak of rot disease. The most effective way to prevent hail damage in apple orchards is to establish hail protection nets.

[0003] While existing hail protection devices in orchards can shield the tops of apple trees, their effectiveness in filtering and collecting hail water is limited. Furthermore, the collected water is not efficiently utilized for irrigation, reducing overall water resource efficiency. Additionally, the modular design of the hail netting is often used as a whole, which is ineffective when used in conjunction with other components. Damage to any part of the netting necessitates replacement of the entire netting, increasing workload and costs associated with hail protection for fruit trees. Summary of the Invention

[0004] This invention provides a hail protection device for apple orchards to solve the problems mentioned in the background art, such as the low efficiency of filtering and collecting water from hail when blocking hail, the low utilization rate of collected water for fruit tree irrigation, and the low efficiency of water resource utilization. In addition, when using hail blocking nets, they are often used as a whole, which is not effective for modular, interlocking, and disassembly-and-reassembled blocking nets.

[0005] This invention provides a hail protection device for apple orchards, including a mounting frame. A lifting rod is slidably connected to the inner wall of the mounting frame, and a sliding rod is slidably connected to the outer wall of the mounting frame.
