TECHNICAL FIELD
[0001] The utility model belongs to fruit tree planting technical field, especially relate to a fruit tree ring binder. BACKGROUND
[0002] The nutrient substance delivery mode of tree includes: delivering the nutrient absorbed by root upward through xylem, and delivering the nutrient produced by photosynthesis of leaf downward through bark. In order to promote the reproductive growth of fruit tree, improve the fruit setting rate, improve the fruit quality, and increase the yield, certain means need to be taken to temporarily interrupt the downward delivery of organic matter, reduce the nutrient supply to root system, make the nutrient accumulate in the upper part, and meet the demand of flowering and fruit development on nutrient.
[0003] The most commonly used in prior art is ring cutting or ring peeling, which is mostly manually cut a circle or two circles along the branch ring peeling place by shovel and other tools. The ring cutting or ring peeling not only needs to cut the nutrient substance delivery channel of bark, but also needs to not damage xylem, and the cutting depth needs to ensure that the bark can heal itself later. Therefore, the operation personnel have very high professional requirements, even if the professional operation personnel also have uneven levels, and it is difficult to ensure the non-damage ring cutting or ring peeling, which often leads to damage of fruit tree, even yellowing and death, and further leads to huge loss of fruit farmers. There are also ring cutting and ring peeling tools with limiting structure in prior art, but the structure is complex, the size is bulky, the operation is complicated, and the tool is not easy to carry.
[0004] There is also a ring lashing method using iron wire in prior art. The iron wire is twisted around the branch by pliers or other tools, and the iron wire is embedded in the bark. This method can block the delivery of nutrient substance without directly damaging the bark, and the iron wire can be cut to restore the delivery when the fruit development is relatively mature, which can effectively avoid the death of fruit tree. However, this method has the following problems: 1. The thickness of iron wire is not easy to control, the operation is complicated, and the tightening degree is not high and not easy to control. When the iron wire is thin, the operation is easy, the tensile strength is not enough, the iron wire is easy to break, and the iron wire is easy to be embedded too deep to damage the tree. When the iron wire is thick, the operation is laborious, and additional assistance is needed to embed the iron wire in the bark, but the uniformity cannot reach the ring lashing effect, and the bark or xylem cannot be guaranteed not to be damaged; 2. The iron wire cannot be reused, and the environmental protection is poor. The iron wire is easy to rust, and after cutting, the iron wire can only be discarded and cannot be used again, which increases the planting cost of fruit farmers. CONTENT OF THE UTILITY MODEL
