First, the principle of transformation If the temporary strain affects the permanent strain, the main branch on the temporary strain will be removed until the temporary strain is removed; if the temporary line affects the permanent line, the temporary line should be the main branch. Second, the transformation of points 1. The orchards that have been closed, all set permanent and temporary strains. Generally, a temporary strain is set for the septum. If the pollination tree is arranged between rows, the pollinated tree should be retained as a permanent strain first. Temporary strain without space, cleared immediately. 2. Orchards that are closed between lines and between plants, set up permanent and temporary lines. It is best to act in a unified manner in the whole park. From the side of the orchard, the temporary row is selected in turn. Can not be unified, can be single-family. When the pollination tree is deployed in a row, attention should be paid to selecting the pollination tree as permanent. When two adjacent rows are selected as permanent lines, they must be retracted and controlled to stretch each other, so that the space between the lines can be opened by 1 meter. 3. Lower the tree height. The temporary line height dropped to about 2.5 meters, and the maximum could not exceed 3 meters; the permanent line height dropped to about 3 meters, and the maximum was no more than 3.5 meters. 4. Reference tree. The permanent tree shape is dominated by free spindles or seven major branches. (1) Sparse layer shape. The lower part is arranged with three main branches, with the first main branch and the second main branch facing northeast or northwest, the third main branch facing south, and the lower main branches rising to 70-80 degrees; 1.3-1.5 from the first floor. m, select the second floor, distribute two main branches east to west, open the angle to 80 to 90 degrees, and select the third floor about 60 centimeters from the second floor, and distribute two main branches one at a time, the south and the north. To 90 degrees. There are 7 main branches in the whole tree, and the distance between main branches in each layer is 10-15 cm. (2) Free spindle shape. The distribution of the main branches is relatively arbitrary, and the lower three main branches can be arranged in a sparsely layered configuration, and can also be freely configured. Three or more main branches retain 7 to 8 small main branches extending uniaxially. Spindle-shaped seeing empty branches, as long as they do not cover each other, ventilation can be light, requiring the branch ratio is less than 1/3. 5. Tree control. In the beginning of spring, paclobutrazol (3 to 5 g) was applied to each branch of long-branch species or short-stemmed branches and trees and water was poured into the base of the trunk. The branches that should be adjusted at an angle should be angled, and the multi-faceted buds of one-year-old branches or light-legged legs should be cultivated. In the spring and summer, we must pay attention to eradicate the sprouts of the cut saws and other places in time to prevent nutrient consumption. Apply more organic fertilizer to control the use of nitrogen fertilizer. If the tree appears prosperous in May, it can be cut at the base of the branch, and the tree is sprayed with 100 to 200 times paclobutrazol and 0.3% of potassium dihydrogen phosphate for 2 to 3 times. Third, pay attention to matters 1. Adjust the trimming tool. Select good quality scissors and saws to ensure that the saw cuts are smooth and disinfect the trimming tools. 2. Remove dead branches. Remove the dead branches first and then sterilize the wounds. 3. Find out the main contradiction. Find out the problems existing in the tree beforehand and focus on solving the problem of air and light transmission. 4. Handle the saw blade. This is the key to the success of tree transformation. 0.75 kg of paint can be used to infiltrate 50 grams of methyl thiophanate powder, stir and apply the wound. 5. Can't be eager for success. Does not necessarily remove the temporary line in a short time. A Sanitary Napkin, sanitary towel, sanitary pad, menstrual pad, or pad is an absorbent item worn by a woman while she is menstruating, while she is recovering from vaginal surgery, for lochia (post-birth bleeding), after an abortion, or in any other situation where it is necessary to absorb a flow of blood from the vagina.The sanitary napkin, have four types, super thin, thin, regular, thick.And the sanitary napkin, have different sizes: 220mm, 240mm,260mm, 290mm,320mm.
