The following three methods of cutting the pear tree in the summer were carefully applied: the heart, namely, strangulation of the birch at the unsuspendable top of the new mat, where the two-to-three leaves had been opened; the screeching, where the unsuspended new stubble had exceeded the length and wooded and the upper end had been cut, which was still being applied; the scrambling, which was a new screeching of more than 40 centimetres of wood, which had been reduced by light and turned 120 ~ 150 centimetres from the base, so that its internal wood was torn but not broken, and its external skin was bent and not broken, and the upper part was bent and the direction of the branch was changed. But none of these three methods can be used for pear trees. Because most of the pear varieties are embryonic, weak and new. With the exception of some of the species in the pear system, which can have a fallow in fertile gardens and rain-fed areas in the south, others grow only once a year, without a fallow and second branches. So neither the nursery, nor the larvae or the primary tree can be trimmed in the summer. Because of the use of heart-picking or cutting, there is no more spasms on medium-sized seedlings and mid-minor trees, which reduces the amount of leaves and affects the nutritional manufacture and accumulation of plantations, does not contribute to the acceleration of seedlings, tree-formings and early fruit production; and strong seedlings and strong trees, which, while using heart-crunches and cuttings, are able to grow their stubbles quickly, have only two branches at best, and consume a large amount of nutrients in the case of stabbing. Most importantly, the branches drawn, the zero to 12 centimetres of the base, are leaves that cannot be sprouted with leaves, the upper part of the centre is not sufficiently developed and has to be cut in winter, resulting in the inefficiency of nutrients and the useless growth of the branches, so that the pear trees cannot be trimmed in the summer with hearts and cuts. It is also not possible to use this method because of the thicker branches of the pear, the unsophisticated wood, which, if used, often break or break in a twist. For pear trees, they are long, thick, strong and vertical, and can only be dealt with in the summer season by pulling branches, other branches, stripping and circumcising。
