Description
Technical Field
The utility model relates to a bud grafting technical field, concretely relates to a novel bud grafting device for hickory nut bud grafting.
Background
The walnut is a deciduous tree of the walnut genus of the juglandaceae family, is one of four nuts in the world, and is also an important woody oil crop. The apocarya, also known as American apocarya, is a high-efficiency ecological economic dry fruit oil tree species with great market competitiveness of a nut variety, namely American and Mexico. In recent years, with the development of the excellent variety selection and the introduction of the excellent variety of the apocarya, the early-maturing, high-yield and high-efficiency cultivation of the apocarya is realized, and the planting of the apocarya obtains unprecedented good benefits. The walnut in south China grows vigorously, but due to small branch angles, various branches are easy to bald and disjointed, the bearing parts are few, and the flower bud differentiation quality is poor. In particular, the apocarya seedling variety has large genetic variation, late fruiting, poor quality and low yield, and seriously restricts the healthy and rapid development of the walnut industry in south China. At present, the cultivation of a large number of high-quality good-quality nursery stocks through grafting is a main way for developing the carya illinoensis industry.
The bud grafting technology is one kind of grafting technology, and includes cutting one bud from branch, inserting the bud into the cut in the stock and binding to heal the bud. The bud grafting is divided into different methods such as bud slice grafting, whistle grafting, pipe bud grafting, bud eye grafting and the like according to different forms, wherein the bud slice grafting is most widely applied. The T-shaped bud grafting method is one of the common bud grafting methods, also called shield-shaped bud grafting method, and is characterized in that when a grafting bud (bud slices are semi-lignified) is cut in a growing season, the grafting bud is held by the left hand, a transverse cutting is carried out at a position 0.5cm above the bud to reach xylem, then the position 2-3 cm below the grafting bud is upwards obliquely cut to the previous transverse cutting position, and the bud slices are taken down. Slightly obliquely and transversely cutting the smooth part of the pre-grafting part on the stock upwards for a time to reach the xylem, cutting off cortex and very thin wood upwards at a position which is about 3cm below (slightly larger than a bud piece), and taking off the bark block on the stock. The bud is put on the T-shaped opening and tied with plastic strip, the bud is exposed outside. When the T-shaped budding method is used, the problems of inconvenient operation and inaccurate positioning are often caused by the bottom-up cutting.
For example, the chinese utility model patent with publication number CN209710785U discloses a budding knife, which comprises a first grab handle component, a second grab handle component, a strip-shaped plate, a fixed knob, a first pin, a second pin and a connecting pin, wherein the first grab handle component comprises a first mounting plate, a first grab handle, a main knife, an auxiliary knife and a fixed pin, the main knife comprises a main knife bottom plate, a main knife blade, a first arc-shaped adjusting groove and a second arc-shaped adjusting groove, the auxiliary knife comprises an auxiliary knife bottom plate, an auxiliary knife blade, a first adjusting hole and a second adjusting hole, and the main knife and the auxiliary knife are rotatably connected through the fixed pin; the second grab handle assembly comprises a second mounting plate, a second grab handle, a balance plate and a supporting pin shaft, and the first grab handle and the second grab handle are rotatably connected through the connecting pin shaft. The utility model provides a budding sword through the angle between rotatory main sword and the vice sword, can control the size of shearing mouth and connecing the scion bud, has the significance to the quality, the plant wound healing rate, the grafting survival rate that improve and connect the scion bud and increase planting economic benefits. The budding knife is extremely inconvenient for cutting and paring from bottom to top at the time.
