  First, planting (transplant):

  1, replanting season

  Deciduous trees: After thawing soil spring sprout before replanting or after thawing soil before replanting in autumn leaves.

  Conifers, broadleaf evergreen: After thawing soil spring sprout before replanting, or stop the growth of new shoots after the fall, frost before replanting.

  2 dead trees make a record before the excavation and replanting as soon as possible.

  3, replanting trees should be used in the original species, but also with similar specifications. If you change the species or specifications shall be coordinated with the original landscape, trees must be consistent with the same section of replanting trees.

  Second, irrigation and drainage:

  1, for the normal growth of trees, from May to November is a critical period for irrigation of trees.

  2, newly planted trees were appropriate period depending on the species and different site conditions, the amount of irrigation.

  3, the survival of the trees have been planted, drought or poor site conditions in the soil in arid environments timely irrigation.

  4, when full irrigation irrigation irrigated, especially in spring and summer, avoid watering less, causing the soil half close.

  5, irrigation should be early summer, late conduct, winter irrigation election conducted at noon.

  6, autumn (late August onwards) appropriate to reduce irrigation, control seedling growth, promote woody seedlings in a timely manner to facilitate the winter.

  7, before winter trees generally pouring water in order to protect the trees in winter and prevent drought.

  8, after the surrounding trees and remove stormwater, water newly planted trees as soon as possible, especially excluded.

  Third, fertilization:

  A wide open fertilizer sources, perennial manure to accumulate organic fertilizer, organic fertilizer to be fully decomposed after application.

  2, dormant fertilization: early spring or late autumn conduct, compost and other organic fertilizers as manure. Can be combined in the winter turn.

  3, growing fertilization: spring or autumn, with manure and inorganic fertilizer available, combined with watering proceed.

  4, the use of fertilizer spreading fertilizer, in the rain when the soil is moist or wet; after watering or fertilizing. Tall trees using pit, dug in around the roots evenly pussy, fertilizer applied into the casing after watering, fertilizing special circumstances with roots outside with a liquid fertilizer sprayer to spray directly on the back of the blade.

  Fourth, pruning, shaping:

  1, dormant pruning: In this period more than deciduous trees, evergreen trees, there is no obvious dormancy, winter pruning the tree will have a negative impact, usually in the late spring cold season has passed trim.

  2, the growing season pruning, also known as Summer Pruning: Pruning time is not too late, or easy to procure and consume nutrients occur Fushao adverse shoots grow, while proper pruning, excessive accumulation of nutrients will reduce adverse plant growth.

  3, deciduous tree pruning: keep the tops of the growth potential, leaving every 20 to 25 cm on the level of the skeleton branches branching points in the skeleton branches must maintain its top growth advantage, keep a certain distance and then every a secondary branches, and so on, Thinning leggy branches, drooping branches, etc.; evergreen broadleaf: keep a good center main branch, rational treatment of skeletal branches, keeping branches evenly distributed; evergreen conifers: When pruning to cultivate balanced growth potential can, under normal circumstances without pruning, but taking care to avoid the formation of double-headed phenomenon dry.

  4, hedge trimmer: Hedge general bud strong, strong branching, resistance to cutting. Generally rule-based pruning to maintain shape and tidy appearance, avoid internal emptiness, the lower empty bald can be.

  5, vine pruning: general rarely entire shear to cut collateral-based, cut off the worm sticks, twigs, properly prune weak branches.

  6, pruning flowers, plants, such as Bauhinia, Begonia, Huang Xin, Magnolia, etc.: in 1 to 2 weeks after flowering to prune to reduce the consumption of nutrients to promote multiple collateral, increasing the amount of flowering the following year; during the winter dormant period , has been basically formed flower buds, flower buds and buds can significantly distinguish, may be appropriate thinning, removing thin branches, twigs disease, sprouting branches, branches without buds, may be appropriate to cut off.

  7, summer pruning flowering plants, such as pomegranate, hibiscus, hydrangea, crape myrtle, etc.; in front of the flower trim; branches in the dormant period of the short-cut, prompting the spring pumping birth stout branches.

  8, trimming winter flowering plants, such as bloom, such as: winter, after Chunhua Xie, turns stub squid, cig stay 3 to 5, to promote the formation of axillary buds more new collateral, often sparse growth period to leggy branches, dense branches, overlapping branches and so on.

  9, several times a year pruning flowering plants, such as roses, crape myrtle, etc.: All branches will be cutting back this winter to promote germination strong branches, stray promptly cut off after the flowers fade, timely elimination growing sprout buds, to promote The new bud formation.

  10, trim the general procedure:

  (1) See: Look trim object inherent growth habit and the specific site conditions, tree main collateral distribution structure is reasonable, and the canopy up and down between the main collateral growth potential is balanced, whether vegetative and reproductive growth of relations and coordination, comprehensive analysis pruning techniques to determine the appropriate measures.

  (2) pumping: some impact on the growth of trees, tree damage, disrupt the tree, perennial pest damage suffered large sticks, sticks and even the backbone of the first saw cut, the trees basically achieve the purpose and requirements of pruning.

  (3) Scissors: Based on the structure and morphology of the tree meets the basic requirements of the aim, then the primary collateral for each specific trim, follow the principle of not leaving without leaving the weak to stay strong, stay outside, using stubs, thinning, etc. technology, the more perfect shaping trees.

  (4) check: After pruning completed, the entire tree be carefully reviewed, right or wrong scissors, cut the drain where correction or give up scissors, starting from the population point of view, to check the impact of the trees adjacent to each other and make adjustments.

  Five weeding:

  1, deep plowing: deep plowing time the leaves of deciduous trees in the conduct; evergreen relatively dormant period before entering conducted. Usually in mid-November to December is appropriate. Deep plowing is generally 15 to 25 cm, master near plant roots Yi Qian, away from the principle of the plant roots can be deep. Flips upside down to the mud, do not immediately clods broken, or early in the sunny sunny weather, the soil moist, but points when performed, can be combined fertilizer organic fertilizer.

  2, weeding: weeds season uninterrupted manual weeding, unless early, except for a small, weed focus under composting promptly carried away, as the case may also use glyphosate, a chemical herbicide nitrofen, etc. controlling.

  Six pest control:

  1, pests: leaf-eating insects, such as slug class, Mino moths, sucking pests such as scale insects, aphids, borers dry pests such as beetles, moths stupid wood, soil pests such as cutworms, grubs.

  2, diseases: root rot, powdery mildew, anthracnose.

  3, implement prevention, comprehensive prevention approach to governance, maintenance of ecological balance, leverage diverse vegetation of the park to protect predators and proliferation, inhibition of pest damage.

  4, good garden plant pests, forecasting work to develop long-term and short-term prevention programs.

  5, prohibited the use of toxic chemicals and organic chlorine, organic mercury chemical pesticides. , Recommended the use of biological agents, such as: rhizosphere Kang, nursery spirit, activate rooting dispersants, withered Bristol, A frost MZ, emamectin benzoate Chlorfenapyr fluorine, interferon, Bacillus thuringiensis, to kill the whole net, charcoal gray frost withered 1 +1 and other effects of pesticides.

  Seven, anti-typhoon and accidents:

  1, before the typhoon hit by line examination of the trees, which do not meet the requirements of the stent timely tightening, with wire, rubber gasket when lashing lashing points should not damage the bark, bamboo can be concatenated fixed.

  2, according to the growth of trees on and street lights, houses and other facilities collision likely too dense branches and twigs, using different levels of thinning and cutting back.

  3, has been heavily skewed to the tree trunk trees, timely stand bracket, after righting work to do to be a typhoon.

  4, trees were blown down by typhoons in time, to be strong crown cut, leaving only the primary branches. To tear, torn lateral to trim large smooth, strengthen conservation and management after planting.

  5 throughout the typhoon season, ready to do the inspection, remedial work after the typhoon timely removal impede traffic, the visual impact of the reinforcements.

  6, where the trees susceptible to frost damage, the winter should take the foundation earth, dressings and other cold trunk measures.

  7, when the snow leaves promptly removed, there is lodging dangerous trees stand bracket protection
