The sagging growth and to control the growing, newly elected to stay on the upper trunk of the main branch at the base of 510cm to reverse 180. So that the level of growth, timely Thinning main branch and trunk branch branches of the competition. In late August, will choose to stay leveled all the main branch 90. So that the level of growth. Methods and the same year 1 Dongjian. (3) through 3 years of tree cultivation, dry high as 50-60cm, height control in 3.5in or so, and maintain the central leader growth advantage, the uniformly horizontal extension configuration 8l0 main branch, main branch base diameter of birth control in its site of Mikie roughness 1/31/2, medium and small form results Zhizu directly with students in the main branch. 4-5 year old trees are the result of winter pruning is a major pest Thinning too dense branches and sticks. 2 cultivation techniques (1) trigger strong cherry branch pruning a free spindle, first of all fertilizer and water management should be strengthened, trigger strong branches, planting trench when planting by stitch, trench depth 60cm,[link widoczny dla zalogowanych], width 80-100cm, trench facilities within each 667m2 Quality Tuza Fei 4000l (g and 50l (g NPK fertilizer, and in early June, early July 1 of the recovery of fertilizer available. 2 ~ 3 years old Shu usually late in September and early March l0 Base Fertilizers,[link widoczny dla zalogowanych], by trenching fertilization, that is, on both sides of the trench in the tree line width 60cm, depth 50cm, high-quality Tuza Fei Shi 3000kg, nitrogen, phosphorus and potassium fertilizer 50l (g, early in June, the recovery in mid-July available chemical fertilizer 1. 4-5 years has been the result of a large cherry tree, autumn Base Fertilizers, the strains of high-quality Tuza Fei Shi 30-50l (g, growing season according to the nutritional status of trees, reasonable topdressing fertilizer available. ( 2) controlled by the potential to promote freedom of spindle-shaped flowers of sweet cherry pruning, shaping basic completion of 3 years, 3 years starting results, so the first 3 years generally start late in May, a 0.5% 0.4% spray of paclobutrazol interval spray 1 l5-20d, and even spray 3 times to control tree vigor, promote differentiation, into the full fruit period, no longer use the MET, or easy to make weak grower and fruit quality. (Yanzhou City, Shandong Province Yan Ju De Forest Dushao Qing Wang Zongwei 272100)-A-Shi fertilizer is a common grape fertilization methods, and its wide by fat, fast fertilizer, fertilizer use efficiency high. General 2h after spraying began to be absorbed, urea spray After 24h 88% absorbed within. flowering spraying a mixed solution of urea and boron can improve fruit set. superphosphate spraying young fruit and mature berries extract,[link widoczny dla zalogowanych], fruit sugar content can significantly improve and enhance disease resistance. berries rapid growth of spraying fertilizer, yields can be increased by 10%, a 1.5% increase in sugar content of 2.5%. berries become soft earth of the spraying solution, increasing production and sweetening. sprayed on grape fertilizer should be applied to master the technical points: 1 suitable spray fertilizer on shoot growth is best reminder before the shoot fertilizer spraying at flowering, fruit flowers stability of steady fruit spraying fertilizer, fruit enlargement in the fruit of strong fertilizer spraying. bud, leaf to flowering before and after the main nitrogen fertilizer; from spring shoots begin to grow, to mature berries,[link widoczny dla zalogowanych], especially the vigorous expansion period to the berries to the best fertilizer spraying: a good fertilizer applied large grape before the spraying and sweet berry enlargement best potash; flowering spray of boron effect is remarkable; berries soften the initial effect of spraying rare earths great. 2 the appropriate concentration of nitrogen used 0.2% to 0.4% of the urea solution, 0 .3% to 0.5% of the ammonium sulfate solution; phosphate 2% a 3% superphosphate solution soaked filter; K 0.5% 0.4% potassium sulphate solution. 1% potassium nitrate solution; potassium dihydrogen phosphate as the phosphorus and potassium fertilizer, spraying concentration of 0.2% ~ 0.3% of the diluted solution; ash is also a good source of potassium, usually 3% of the leaching solution sprayed; trace element fertilizer 0.1 % ~ 0.2% of borax or boric acid solution, 0.o5% 0.15% a zinc sulfate solution, 0.1% magnesium sulfate solution, 0.1% solution of ferrous sulfate solution 36, 0.05 % of a manganese sulfate solution, 0.1%; RE 0.1% to 0.05% of the farm of a rare earth nitrate solution, 0.1% solution of rare earth moving plant Po 3. foliar spray fertilizer spraying method should be tender shoot, young leaf and surface of leaf-based, sought to fine mist particles to facilitate the uniform clouds, spray to the leaves all wet and dripping liquid fertilizer is not limited to the whereabouts of. usually sprayed on the growth and development cycle 4-6 times. According to needs can be a variety of Ye Mianfei Spraying Mixture, but also with pesticides, plant growth regulator spray mix. preferably sprayed on cloudy days, sunny days are advised not strong, especially in the afternoon sun for the evening.
