The quality of Taoyuan's spring management directly determines the output and quality of the year, and will also have a greater impact on the production of the following year. Therefore, in spring management, we should pay special attention to the following three links: Fertilization and watering The current peach tree has entered the period of budding, flowering, fruit setting and new shoot growth. In order to meet the nutrient requirements of tree growth and young fruit development, topdressing before flowering is particularly important, especially for weaker growing trees A peach orchard with high annual output is conducive to the flowers blooming neatly and uniformly, improving fruit setting rate and early shoot growth. Before flowering, an appropriate amount of nitrogen fertilizer can be added to promote fruit setting and tree growth, but the amount should be paid attention to so as not to cause new shoots to grow and increase fruit drop. Watering immediately after top dressing, can choose furrow application, hole application, strip application, radial or ring application, and can also be combined with watering application. Thinning Flowers and Thinning Fruits At present, thinning flowers mainly consist of multiple cuts before flowering and varieties with high fruit setting rate (Chun Yan, Okubo, Nectarine, etc.). The degree of thinning should depend on the tree vigor, the amount of fruit branches remaining and the spring climate conditions. Generally, short, medium and long fruit branches leave 2, 3 and 4 flower buds respectively, and the long branches leave 5-6 flower buds. Fruit thinning time, shortly after flowering, the first fruit thinning is carried out when young fruit can separate large and small fruits. Varieties with a high fruit setting rate can be thinned early, while varieties with a low fruit setting rate are unstable. The amount of fruit retention should be comprehensively considered according to factors such as tree age, variety, crown size, growth potential, fertilizer and water supply conditions, last year's yield and the number of flowering in that year. For young trees, 30-40 cm fruit branches generally leave 3-4 fruits, 20-30 cm fruit branches leave 2-3 fruits, and fruit branches below 20 cm leave 1-2 fruits. In the full fruit period, the long, medium, and short-leaf twigs leave 3, 2, and 1 fruit respectively, the old tree long-fruit twigs leave 2 fruits, the middle-fruit twig leaves 1 fruit, and the short-fruit twigs and leaf clumps leave no fruit. Pest control In early April (before germination), spray 4-5 Baume's Lithium Sulphur Mixture once, or 45% crystal Lithium Sulphur Mixture 30 times, spray carefully and evenly. In the peach orchard where the disease was serious last year, Bordeaux mixture can be sprayed 1: 2: 120 times before flowering, but it must be more than 12 days apart from the previous spraying time of the stone sulfur mixture. At the beginning of April (before the peach tree blooms), once aphids are found, they can be controlled with 10% imidacloprid 2000 times solution; anthracnose can be controlled with 80% anthrax fumei 500 times solution; brown rot disease can be treated with 70% desenzin 500 times solution or 50% speed Killing 1000-1500 times liquid prevention. In mid-to-late April, after the peach trees had flowered, the leaves of the leaf shrinkage disease were manually removed to kill the overwintering larvae such as the red-necked beetle. It can be sprayed with 600 times of mancozeb or 70% of thiophanate-methyl 1000 times + agricultural streptomycin 2000 times + 10% imidacloprid 2000 times + 20% pyrethroid 2000 times, once every 10 days. , Mainly to prevent leaf shrinkage, bacterial and fungal perforation, brown rot, aphids, pears, beetles and scale insects.
