Summary of the invention
The object of this invention is to provide a kind of American red-maple cultivation management technology method, can disease and pest control thus improve further survival rate, the growth rate of red maple better.
In order to achieve the above object, technical solution of the present invention comprise selection of land and whole, transplant, irrigate and draining, prune, topdress, intertill and clean tillage, the extermination of disease and insect pest, loosen the soil and the technology such as to earth up, make that American red-maple color is brilliant, tree-shaped is upright, tree crown is clean and tidy, healthy and strong, disease and insect resistance, improves survival rate and the growth rate of American red-maple.Concrete implementation step is as follows:
1) selection of land and whole: in soil, be applicable to neutral soil, acid ground, and lime soil, or red soil yellow soil area; Need special it is to be noted that the draining in plot wants good, the drought-enduring fearness flood of American red-maple; Carry out after choosing planting area turning over, smooth, attention will be deep ploughed, the degree of depth is at 45-55cm, base manure is imposed before ploughing, especially note the demand of phosphorus, potash fertilizer, generally use potassium sulfate type balance composite fertilizer, unavailable chloride composite fertilizer, easy to be unfavorable to plant strain growth on the one hand, easily cause soil compaction on the other hand;
2) transplant: before transplanting, need first to prune sapling, remove middle and long carefully the following of part, and water sprout, trunk, the nursery stock of more than 2cm, must bring native ball; According to local climate, generally in the season of Acclimation temperature in spring, mid or late Febuary-mid or late April, temperature is when 15-20 DEG C; Soil bulb diameter 35-80cm larger than trunk diameter, the ratio that goes out greatly of the larger corresponding native bulb diameter of trunk diameter wants many, such as xeromenia 3cm, and native bulb diameter is 40cm; Trunk 8cm, native bulb diameter is 85cm; The excavated diameter 25cm larger than the diameter of native ball in cave, the transplanting cave of depth ratio soil ball height height 30-50cm, sapling is transplanted in cave, correct nursery stock, fill chesson, spread paving evenly, compacting layer by layer, transplanting depth is that native ball top layer flushes with earth's surface or exceeds 5cm, and will note watering permeable after transplanting, the spacing of sapling will control according to the diameter of institute's transplanted seedling;
3) irrigation and draining: the sapling newly transplanted will mainly be watered, according to weather and rainfall, within 7-10 days, water a water, keep the wettability on blade face, and irrigate rear and must draining be noted in rainy season, discharge ponding, carry out drain ditch, must prevent root system from soaking in water for a long time;
4) prune: American red-maple does not need too many pruning early stage yet, keep the stalwartness of trunk, tree crown well-balanced; The pruning in vegetative period generally late May-mid-September, the pruning of resting stage generally mid or late November-late March of Second Year; Treat the nursery stock of different development condition, the method for pruning is different: 1. grow substantially balanced nursery stock, mainly carry out appropriate sparse branching in shaping, dredges and removes over growth, overstocked intersection branch, weak and have the branch of damage by disease and insect; 2. to growing unbalanced nursery stock, note in trimming curbing the violent and assist the weak, weak to growth, dredge and remove dying and withered branch, the opening degree of minimizing side shoot; One side strong to growth, strengthens side shoot opening width; 3. noting crown height ratio (length of seedling hat and the ratio of the height of nursery stock) according to development condition, is will retain suitable seedling hat and leaf area, to ensure the vigorous growth of nursery stock on the one hand; Be the side shoot progressively eliminating seedling crown base portion in the process of growth of nursery stock on the other hand, to ensure that the height of trunk constantly grows tall, irritability reaches required trunk height;
5) topdress: early growth period, based on instant nitrogenousfertilizer, wherein the ratio of N P and K is about 6:1:3, and every mu controls at 10kg, this period Effects of Fertilization Frequency relatively higher, and thinly to execute, within 10 days to 1 month, spread fertilizer over the fields according to growing state or water and execute once; After nursery stock transplanting about about half a year, in the mid-term of seedling growth, sapling young leaves is decontroled, and enters the phase of coming into leaves, executes containing nitrogen composite fertilizer, to increase the organic principle of soil, regulates the mellowness of soil and improves anti-dry prevention waterlogging ability; Enter the quick Later growth of nursery stock, about November, to execute azophoska composite fertilizer, can adopt and around spread manuer in holes or circulating application, wherein the ratio of N P and K about controls at 2:3:5, and notes at the both sides of nursery stock trench digging later stage winter dressing;
6) intertill and clean tillage: American red-maple, to many herbicide sensitives, can't blindly use, and must carry out small-scale test, to prevent from bringing large-area injury; Be easy to by weeds impact growth during American red-maple seedling, therefore require that the surrounding of seedling often will carry out artificial weeding, later stage can be combined with the mode using weeding by machine, generally chemical weed control agent medicine weed eradication just can be adopted at about 2 years after field planting, but liquid can not encounter blade, to prevent from hindering seedling; The red maple paying special attention to transplant, if trunk diameter is little, needs slotting bamboo pole to prick husband, scrapes lodging to prevent wind;
7) extermination of disease and insect pest: damping off and damping off easily occur seedling; Prophylactico-therapeutic measures mainly contains following methods: mould clever 450 times of liquid are disliked in damping off their early stage spray 15%; Damping off sprays 20% tolelofos-methyl missible oil, 1000 times of liquid; Spray 72.2% general aqua 800 times of liquid of making every effort to overcome in two sick simultaneous situations and add 50% thiram wettable powder, 800 times of liquid; Every square metre of spraying liquid 2-3kg; Virus disease also happens occasionally, and prophylactico-therapeutic measures mainly contains: remove diseased plant in time, avoids propagating; Can spray with Junkeduke; The sick leaf of manual removal;
Insect pest mainly contains: 1. soil insect has grub, mole cricket etc. to bite seedling and basal part of stem, easily causes nursery stock withered, Le Siben 1000 times of liquid or 50% phoxim emulsifiable concentrate 1000-1200 times liquid can be adopted to water root; 2. chafer, slug moth, aphid etc. often eat the blade of red maple, cause seedling growth bad, as: aphid, scarabs, can adopt 10% Imidacloprid powder 1200-1500 times of liquid spraying etc.; 3. the red maple limb of the harm such as longicorn, borer, causes the even whole strain of red maple seedlings deadwood dead, can contain and send out the phase 6-7 month with 4.5% beta-cypermethrin 1500-2000 times of liquid spray tree crown, spray once, connect spray 2 times about the two weeks of interval at Cerambycid beetles; Or also seal with viscosity earth to agricultural chemicals such as limb injection dichlorvos or Le Siben etc. at gallery mouth;
8) loosen the soil and ridging: loosen the soil according to soil property situation every year at 2-5 time, if planting area irrigation conditions is not very desirable, suitably increase number of times, will loosen the soil in time in rainfall with after irrigating and when soil hardens.
Preferred above-mentioned steps 1) described in the deep ploughing degree of depth be 52cm.
Above-mentioned steps 2) described in transplanting spring mid-April-late April, temperature is carried out when 15-20 DEG C, and transplanting depth is native ball top layer flushes with earth's surface.
