Saplings build crowns Pay attention to the plastic tree seedlings in the spring to do a good job, most of the three main branches naturally happy shape, usually after a fixed value at a distance of 50 cm from the ground to cut off. Note that there should be 6-8 full shoots under the excision, and the spring sprouts should be selected after 3-4 shoots with robust growth and different directions as the main shoots. The main branch has a certain distance from the point of birth, and the strength and weakness can be controlled by changing the angle. The remaining shoots, if they compete with the main branch, are to be removed, and weak branches are used as supplementary branches. From May to June, the main branch grows robustly, and the main branch with a length of 60-80 cm can pick up the heart, promote secondary shoots, cultivate secondary main branches and secondary main branches, and expand the canopy. Clipping buds generally remain on the outside, and the other side buds that germinate underneath retain a suitable and well-growth branch as a secondary main branch. The sub-main branches left by each main branch should be on the same side to avoid emptiness or collision. Secondary branches can be cultivated in such a year, and the second branch can be left for the second time to form a canopy, which will be put into production in the third year. Fertilizing soil For newly-developed Taoyuan, it is necessary to do a good job of expanding the soil, and in the original open-pit or trenching area, dig deep trenches or strips about 40 cm deep, and apply organic fertilizer to improve the soil. In addition, fertilizers such as Urea can be topdressed before each growing season to promote shoot growth. The gap in the young garden can be intercropped with various crops to increase income. Rice stalks can be used as fertilizers for burying or covering. Mixing with leguminous or leguminous crops and legumes will be most beneficial to the cultivation of soil and can also be used as feed. The slope protection grass can be planted, and it is better to cover the ground with a green crop. Peach trees are afraid of standing water, so be sure to pay attention to drainage during the rainy season. Drainage should be cleaned up and silt cultured on the tree tray. Dry season tree trays can be covered with loose soil to reduce evaporation loss. Before fruit tree flower top dressing From March to March, peach trees have entered the period of budding, flowering, fruit setting and shoot growth. In order to meet the growth of tree shoots and nutrient requirements for young fruit development, top dressing is particularly important before flowering, especially for trees with weak growing vigor. In Taoyuan, where the yield was too high last year, an appropriate amount of nitrogen fertilizer was added before flowering to promote fruit set and tree growth. However, attention should be paid to the dosage so as to avoid causing new shoot growth and increasing fruit drop. For 1-3 year old saplings, 150-200 g urea/strain is applied, and the adult tree with weaker trees is generally applied with about 300-500 g of urea per strain. For the growth tree with strong growth potential, the fertilizer can not be applied. For adult trees that enter rich production period, little or no nitrogen fertilizer should be applied in spring. During the peach and young fruit period, it is most afraid of water and drought. The accumulation of water in the orchard will affect the absorption capacity of the root system, and it will also affect the necrosis of new roots, resulting in fruit drop and fruit drop. Therefore, the orchard in the plains must clear the ditches, clear the mud, and fill the gaps. In case of drought, it is necessary to promptly resist drought, which can be carried out in the form of ditching, wetting, or spraying. At the same time, the quick-acting fertilizer can be mixed into the water and applied to the Taoyuan along with the water. Do a good job of pest control Peach trees are vulnerable to diseases such as anthrax and aphids in the spring. In order to prevent the early pests and diseases of peach trees, before the peach tree's flower buds and leaf buds protrude out of the peach tree epidermis, the trees should be sprayed with a new high-fat film and the trees should be used to apply the trees to prevent pests from invading. Once aphids are detected, 10% imidacloprid can be used for 2000 times; anthrax can be controlled with 80% anthraquinone and 500 times; for brown rot it can be controlled with 70% dexamethasone 500 times or 50% sulfacin 1000-1500 times. The gum disease can be scraped off with porcelain tiles to remove the lesions and apply 30 times liquid toxin.
