For an adult fruit tree, the key point is that part of the upper part germinates, and the branches and buds cut in winter germinate. According to the position and direction, space and buds of the tree, one or two directions are flat, the buds are strong, and the rest are removed. At the same time, for some highly grafted peach trees, the bud eyes outside the grafted buds should be removed in time to facilitate the germination and growth of the grafted buds. For young trees of new varieties, the buds under the plastic belt should be pulled out immediately after germination to reduce nutrient consumption. Then, according to the requirement of keeping trees as needed, according to the principle of "proper spacing, flat direction and different direction", leave buds that meet the requirements on the shaping table and remove all unnecessary buds. Of course, if the stems of young trees germinate, they should be pulled out in time.
Picking the heart is to pick the twigs at the top of the growing twigs together with the tender leaves. Its purpose is to control the growth of branches, promote early germination and get rich, so as to achieve the purpose of relieving trees and accelerating the early modeling of trees. Generally speaking, 40-50 cm is reserved for the extension branches of the main branch and the lateral branch, and 30 cm is selected for the new branch of the lateral branch, so that the flower bud differentiation is better. Of course, it should be carried out according to the actual situation in specific production. For example, the fruit center produces a "happy" tree. In childhood, when the stock price index is strong and the stock price index is weak, we can take off the Kangzhou index and weaken the growth momentum to achieve three main balanced growth goals. Peach trees grow fast and the fruit development time is short, so fertilization should be timely and reasonable. Fertilization in spring mainly refers to fertilization before germination. Fertilization time should not exceed the end of February, and fertilization in advance is better. Fertilizer types include chemical ammonium bicarbonate, phosphate fertilizer, potassium fertilizer and organic fertilizer. Peach trees produce 35-50 kg of fruit, 40 kg of high-quality decomposed livestock manure, 0.25 kg of urea, 0. 15 kg of calcium superphosphate and 0.4 kg of potassium chloride. If the weather is dry or rainy before germination, sprinkle light manure to fight drought or drain water and prevent stains.
At flowering stage, carbon or urea is the main fertilizer. During this period, about 0.5 kg of urea was applied to the tree of the Holy Spirit. Fully watering for 3 ~ 5 days after fertilization is beneficial to the whole yard as a hoe to accumulate nutrients and improve the fruit setting rate. In mid-March, one week before planting, the newly-built Taoyuan should cover the base of coarse fertilizer such as decomposed organic fertilizer and chaff at Jingjiakou, return the soil to make the soil sink, and carry out high-standard planting. Various branches of peach trees form buds, blossom and bear fruit, and artificial moisturizing is repeated many times, so the fruit hit rate is generally high. Many results are obtained in an uncontrolled way. Peach trees are overloaded every year, with many fruit trees, small single fruit, large stone, thin meat, light taste, poor quality and poor commodity value. At the same time, trees will rapidly weaken, greatly reducing and shortening the harvest period and economic life. In order to keep peach trees in a state of high yield, stable yield and high quality, it is necessary to carry out small fruit in time and properly.
