Hawthorn seedling technology

High. 1m above the elevation seedlings, diameter 1.2cm or more, root length more than 20cm, or more lateral section l5, and the interface well, full, robust, no pests. 3 seedlings before planting dig scheduled pit,[link widoczny dla zalogowanych], foreign soil, enough base fertilizer,[link widoczny dla zalogowanych], to create favorable conditions for root development. Planting density should be 4x5m, digging high and wide, deep lx0.8x0.6m. Spring planting should begin to sprout when the cultivation of persimmon seedlings mainly to free from damage, since to do cultivation, transportation, plant three rapidly. 4 Fertility water management persimmon tree is deep-rooted tree species, soil improvement should be extended to increase hole fertilizer to tree vigor Wang Zhuang. Persimmon trees in acid soils prone to root rot, when the PH value is too low should be improved. Persimmon tree in the winter to put into expanding hole improving soil, backfill surface, the strains of pigs and cattle manure applied 50kg or calcium magnesium phosphate 1-1.5kg, after mixing with the topsoil fill the lower deck. High-yield trees per acre should be applied full of pure N6.5kg, pure P2.5kg, pure K0.6kg, fertilizer should not be too high concentrations, can be divided into multiple application. General pouring water sprout water, flowers before the water, swollen water and wintering water, keep the soil moist. 5 persimmon tree pruning young trees early results favor of Dong Jian,[link widoczny dla zalogowanych], high and stable yield of adult trees, old trees Rejuvenation. Dong Jian generally leaves the next spring after bud before. 5.1 Select the appropriate pruning young trees 3 to 4 branches to do the backbone of the branches, generally do not stubs, and Thinning near the same branch and Wang to the weak branches. Now generally happy with more natural form of the main branch. Plastic surgery, the temporary retention center dry, cut each 1 / 2 to 1 / 3, to keep happy state, once the crown form, which cut off the central leader. 5.2.1 5.2 full fruit period to adjust the backbone of the tree branch pruning perspective, balance internal and external growth forces. Large branches should be of too much points on Thinning, and promote the growth of branches bore, twigs group culture results and support the growth of large sticks outward from the top, and gradually replace the original branch, main branch angle of elevation. 5.2.2 The combination of sparse reduction, training bore branches. Retraction is too high, too strong Zhizu to prevent the results of the relocation site, prompting the rear is updated sticks, and stay strong to weak. The results are generally not cutting back branches, cut the dense branches, leggy branches, cross sticks, twigs disease, so that a reasonable distribution branches. Branches 5.2-3 stay prepared to overcome the size of the year. The results of the branches each year, or 1 / 3 as a result mother to be prepared to shoot a short cut, so the results every year, to extend the results of life. 5.3 Tree pruning old persimmon tree, hidden by long life and bud germination ability, can use this feature, several update and maintain tree vigor enduring, extending the results of life. 6 6.1 Winter clearance garden pest control to reduce overwintering pest base. With winter pruning diseased fruits should be thoroughly clean, disease pedicle, dead branches and leaves, clean source of overwintering pests. Spring germination time before 6.2 5 degrees lime sulfur spray or 95% oil emulsion 150 times. 6.3 Control persimmon cotton Kuwana, Shi Di insects, and other major pests Drosicha Kuwana control based on the above, can be scraped Laoshu Pi and use 5 ~ l0 times omethoate coated ring, the effect is significant. Also make use of Bacillus thuringiensis, or diflubenzuron and other biological pesticides to control leaf-eating pests. (Author: Zanhuang County, Hebei Province Forestry Bureau) has been down or off by a green touch to survive; such as bud black, shoot film shrinkage, the petiole is not dead in the bud survival, they should immediately make connection. Poured on the cold water once before, it is best not to plastic strip solution. 5.2 The management of the second year of the second year after grafting in early spring before the sap flows, for all budding seedlings in the bud at the first cut 0.4cm above the anvil, cut 17I back to smooth slightly tilted to the bud. Lift plastic tie bar. Anvil crown cut off, the stock will be issued a large number of sprouts at the base, should be checked in time,[link widoczny dla zalogowanych], erase as soon as possible. Enhance fertilizer water to promote growth. Autumn Chupu. 6.1 6 pest control seedling damping-off which is based on the Ministry of dried roots characterized the early growth of hawthorn rootstock major diseases, the slightest carelessness can cause a large seedling death. Control methods are: Caesar per acre before planting 1.5 ~ 2.5kg, ferrous sulfate, or a 44 for a 300-fold in the planting of ferrous sulfate with watered roots, when 4 true leaves grow again when the second water , the basic control of damping-off can occur. 6.2 Powdery mildew is a major disease hawthorn seedlings growing season, leaves and stems covered with white powder spots, if not control, rootstock seedlings, thin, hard skin from the severe impact of grafting, and even cause Simiao. Thus from the beginning in June, every 15 to 20 days with 0.3 degrees of lime sulfur or body fluid control and with 800 times the Taub time, even three times to achieve the control purpose spray. 6.3 There are gray weevil pests, aphids A,[link widoczny dla zalogowanych], scarabs, etc., seedling damage is very serious, must be timely prevention. Main method is: find these pests in time 1500 times dimethoate spray control. (Author: Forest Inventory and Planning Institute of Chengde in Hebei Chengde City, Hebei Province Forestry Bureau)
