Pears are important cultivated fruit trees in China, and the area of the Chinese pear orchard is 112.7 million hectares which account for 71.9 percent of the total area of the world pear orchard, counted by Ministry of agriculture in 2015; the yield of the pome is 1869.9 ten thousand tons, which accounts for 68.6 percent of the total yield of the pome in the world; area and yield were first in the world. Pear production is always an important post industry for increasing income and leading to wealth of farmers in China and is also one of main agricultural products for earning foreign exchange in exports of China.
The cultivation of pear trees is an industry with long production period, high technical requirement and continuous production. The pear tree pruning is an important means in pear tree cultivation management measures, the pear trees can have neat and consistent tree shapes, and management of pear gardens is convenient to implement. The fruit tree pruning machine can save pesticide and fertilizer, improve ventilation and light transmission conditions, reduce plant diseases and insect pests, reduce orchard production cost and regulate and control fruit yield and quality by reasonably pruning. The traditional pear tree pruning is usually carried out only in winter, uncontrollable factors are large, the pruning is easy to be over-heavy, and a large number of vegetative shoots germinate in the next year, so that the vegetative growth and the reproductive growth are unbalanced, and the yield in the next year is influenced.
The traditional pear tree pruning method is winter pruning. Trimming time: a pear tree dormancy period; the pruning method comprises the following steps: the first step is to remove the dense big branches, the second step is to remove a large number of redundant annual branches, the third step is to short the peripheral extension branches on the bone trunk branches, and the fourth step is to retract the overlength or weak result branches. The pruning method is easy to cause over-heavy pruning, and a large number of vegetative shoots germinate next year, so that the vegetative growth and the reproductive growth are out of balance, and the yield of the next year is influenced. The saw is used for removing big branches, so the labor intensity is high; when one-year branches at the overhigh parts are thinned, the ladder needs to be climbed, and the operation difficulty is high. The biggest problem exists is that the branch remaining amount is not well grasped, and the remaining vegetative branches are not necessarily developed according to the pruning target, and the controllability is poor.
For years, a great deal of scientific research and experiments are carried out on the subject of how to prune the pear trees to improve the pear quality, and the pruning method for the pear trees is invented in summary. The method adopts various technical means in the growth period of the pear tree, does not need scissors and saws, guides the branch tips to develop towards a set target, has strong controllability and simple and convenient operation, solves the key problem that the method can well adjust the contradiction between the vegetative growth and reproductive growth of the tree body, achieves the aims of ventilation, light transmission and nutrient balance of the tree body and realizes the effect of high quality and stable yield. Meanwhile, the problems of large amount of labor for pruning in winter, waste of fertilizer use and big and small years of pear tree fruiting are solved.

The bud on the back refers to the bud growing on the back of the main branch and the sub-main branch, and the bud grows vertically upwards after germination.
3. When the young shoots grow to 5cm, the branches on the back, the dense branches and the redundant peripheral extension branches are removed. The bud picking method comprises the following steps: the young shoots are removed from the base with the thumb and forefinger without leaving a stump, which will not branch. The branch on the back is a vegetative branch growing on the back of the main branch and the sub-main branch and growing vertically upwards. The dense branch refers to a nutrition branch which grows on the main branch, the sub-main branch and the central leading trunk and is closely spaced, or a plurality of nutrition branches which sprout at one bud. The extension branches refer to vegetative branches growing at the top ends of the main branches, the sub-main branches and the central leading trunk, and only 1 vegetative branch extending along the periphery of a single shaft is reserved within 30cm of the top end.
4. When the young shoots grow to 15cm, pinching. The pinching method comprises the following steps: all the tips of the new tips growing on the main branches, the sub-main branches and the central leading trunk are removed by using the thumb and the index finger, and the rapid growth of the tips is controlled (except for the fostering branches, the peripheral extension branches and the new tips with the length less than 15 cm). And removing all new shoots which continue to grow after pinching every half month, and repeating for 4-5 times until the new shoots stop growing.
5. And (4) thinning the spindly branches. The seedlings grow on the annual branches which are not full of the inner cavities of the tree crowns and grow vertically. The pruning method comprises the following steps: the residual pile is removed from the base in time without remaining residual pile, and the residual pile is removed in time at any time.
Example of the experiment 1: 2013. 2014 and 2015 years Jinjing pear is continuously subjected to three years of comparison of fertilizing amount and pesticide application times by adopting the method and a conventional winter pruning method.
The bud carving principle is as follows:
1. the bud carving principle is as follows:
in order to make the bud carving technique of fruit trees have the function of improving the yield and quality of fruits, buds need to be timely and timely in spring, and the bud carving technique needs to be correctly applied.
Bud carving is carried out on the fruit trees, so that the bone trunk branches can be directionally positioned and cultured, and a good tree body structure is built; high-quality medium branches and short branches are formed by centralized nutrition, and fruiting branch groups are further cultured, so that trees can bear fruits early. Bud carving can also supplement deficient branches, correct crown deviation, inhibit strength and weakness, regulate branch growth, balance tree vigor and ensure stable yield of trees.
Whether the bud carving can obviously play the role is critical, and timely bud carving are critical. Directionally positioning the bud carving, wherein the bud carving time is earlier, and the bud carving is better in the period from 'frightening' to 'spring minutes'; the bud carving can be carried out before and after 'Qingming' by promoting the bud carving of the medium branch and the short branch. Bud carving is early, and the carved bud is easy to freeze; and (3) the carved buds are too late, after the carved buds germinate, the drawn branches stop growing early, leaves on the branches are few, the leaf area is small, and the flowers are difficult to grow. The day of bud carving should be selected to avoid the attack of cold flow.
2. Carefully operating during bud carving: the number of buds to be carved is determined carefully, and is determined according to the characteristics of varieties, the strength of trees, the growth vigor of branches, the planting positions of branches and the purpose of carving buds. The number of carved buds is generally more than that of the common varieties; the varieties with low germination rate are more than the varieties with high germination rate. The strong tree can be carved with more buds, the moderate tree needs to be carved with less buds, and the weak and thin long branches do not need to be carved with buds. The bud on the thick long branch can be etched more, and the bud on the thin and weak long branch is not etched. The bone trunk branches are provided with a few carved buds, the auxiliary branch branches are provided with a plurality of carved buds, but the buds are not suitable to be carved, so that the tree form disorder is avoided.
And (3) directionally positioning and carving the bud, namely cutting down the bud closely to a bud tip 1-2 mm away from the bud tip without damaging a bud body, and slightly carving the bud into xylem by uniformly applying force on the cutting down. The bud carving of the medium and short branches is promoted generally, the cut is far away from the bud body, the cut is 5 mm away from the bud body, the carving is light, only the cortex is scratched, the xylem is not hurt, but the epidermis is not scratched and the cortex is not penetrated. The distance between the incision and the bud to be carved needs to be accurately grasped, the force for carving is light and heavy, and the carving depth is related to the effect of the bud carving and is also the key for the success or failure of the bud carving. The distance between the knife edge and the bud body is too close, so that the bud body is easy to be damaged; the distance is too far away, and the buds are not easy to germinate. The bud carving force is too violent, the xylem is damaged too deeply, and the branches are easy to break; the carving is too light, and the effect is difficult to achieve without carving the transparent layer.

Table 2: comparing the quality of the Jinjing pear with the conventional method
As shown in the experimental example 1 and the experimental example 2, after pruning is carried out in 2013 by adopting the method, the application amount of compound fertilizer is 0.5 Kg less for each plant, wherein 1Kg (15-15-15) of compound fertilizer is applied; the number of times of insecticide application in the whole year is 8, and the number of times of insecticide application is 2 times less than that of the conventional pruning method; the soluble solid is 10.2 percent and is 0.6 percent higher than that of the conventional pruning method; the yield of the single plant is 23.2 Kg, which is 1Kg higher than that of the conventional pruning method. After pruning is carried out in 2014 by adopting the method, 1Kg (15-15-15) of compound fertilizer is applied to each plant, and 0.5 Kg of compound fertilizer is applied less than that applied by the conventional pruning method; the number of times of insecticide application in the whole year is 8, and the number of times of insecticide application is 2 times less than that of the conventional pruning method; the soluble solid is 10.5 percent, which is 0.7 percent higher than that of the conventional pruning method; the yield of a single plant is 31.5 Kg, which is 1.7 Kg higher than that of the conventional pruning method; in 2015, after pruning by adopting the method, fertilizing 1Kg (15-15-15) of compound fertilizer per plant, and fertilizing 0.5 Kg of compound fertilizer less than that of the conventional pruning method; the number of times of insecticide application in the whole year is 8, and the number of times of insecticide application is 2 times less than that of the conventional pruning method; the soluble solid is 10 percent, which is 0.6 percent higher than that of the conventional pruning method; the yield of the single plant is 36.2Kg, which is 1.7 Kg higher than that of the conventional pruning method.
In conclusion, by adopting the method for golden crystal pears in 2013, 2014 and 2015 for three consecutive years, the consumption of fertilizers can be reduced by more than 30%, the consumption of pesticides can be reduced by about 20%, the yield of pears can be increased by more than 8%, and the soluble solids of pears can be increased by more than 0.5%. Therefore, the method can improve the pear quality, and solve the problems of large pruning amount, difficult insecticide spraying, large labor amount, fertilizer use waste and big and small pear tree fruiting years in winter.
