Peach blossom is the envoy, open in spring in spring.A lot of people was engaged in the research of peach blossom flowering regulation, but current present situation is: generally by HORMONE TREATMENT, can only make peach blossom advance flowering period or postpone 3-6 days; Adopt booth heat treatment, can only 20-30 days be shifted to an earlier date; Utilize chemical method to break ornamental peach natural dormancy and in conjunction with the technical measures of facility cultivation, the regulation and control ornamental peach florescence, provide red, polyphyll ornamental peach goes on the market at Spring Festival; Peach blossom, by heat treatment again after potted plant, deepfreeze, also can only make peach blossom be advanced to and bloom the 1-2 month.Even if under special unusual weather condition, peach blossom is sporadicly opening in autumn, but the amount of blooming few, there is no population effect, appreciation effect is very poor, and extremely unstable.

After China realizes long holidays on National Day, much using peach blossom as the scenic spot mainly viewed and admired a little because scenery is dull, domestic visitors is also little, is difficult to share the effect brought long holidays on National Day.If peach blossom can be made to bloom National Day in autumn, particularly, a spotlight at scenic spot will be become, for immeasurable economic benefit is brought at these scenic spots.

Summary of the invention

For the problems referred to above, the object of this invention is to provide a kind of method regulating the ornamental peach florescence, the method can make peach blossom advance flowering period more than 150 days.

A kind of method at ornamental peach florescence that regulates of the present invention comprises the steps:

(1), Fruit variety: select the kind in ornamental peach to plant, the Shan Hong in ornamental peach kind, purple leaf peach, stone horse be safflower, the beautiful elderly person for whom a birthday celebration is being held of rosy clouds, Shou Bai, product rosy clouds early;

(2), heavy dressing in winter fertilizer: after early December, peach was fallen leaves, the fertilising cave of long 60cm, wide 20cm, dark 20cm is dug in both sides corresponding under tree crown, and apply fertilizer, every strain 10-25 kilogram, then covers with original soil;

(3), rear pruning is spent spring: when next spring, peach blossom tune was thanked, spray is stayed 1/3 cutting back, and except branch of preventing or cure a disease, deadwood and young fruit, make tree crown be dome-type; Full garden sprays bactericide once after pruning;

(4), spring topdresses: during the long 10-15cm of peach young sprout, nitrogen of spreading manuer in holes: phosphorus: potassium is the composite fertilizer of 15:15:15, every strain 0.3-1 kilogram; Every 10-15 days, the potassium dihydrogen phosphate of foliage-spray 1% and the amino acid compound trace element fertilizer mixed solution of 0.5%, the amount of spraying drenches, until May 30 with blade face; After this every 10-15 days, the potassium dihydrogen phosphate of foliage-spray 1%, the amount of spraying drenches, until mid-August with blade face;

(5), disleave process: the blade on peach is removed clean; Disleave method has two kinds, and one is manually pluck the blade on most peach, and two is with 40% ethephon agent 100-150 milliliter, converts the spraying of 50 kilograms, clear water, by the spray of peach complete stool thoroughly;

(6), growing environment is controlled: in 10 days after peach blossom disleave process, make peach be in drought status as far as possible; In disleave after 15 days, when fine, temperature is more than 25 DEG C, water permeable in the morning, makes water capacity maintain 70-80%, and tree crown watering sooner or later, until peach blossom is open; Peach blossom start open after, become a fine day, water in soil in morning face, tree crown watering at dusk, keep ground moistening, until peach blossom is bloomed.

The predetermined full-bloom stage of basis of time of disleave process in described step (5) and determine: make peach blossom in full bloom on National Day, disleave should be completed before August 25; Peach blossom was bloomed in November, disleave should be completed before September 15.

Beneficial effect of the present invention: the basic law that this method is grown according to peach blossom, " fertilizers regulation, disleave process, moisture regulate " comprehensive technical measure system is adopted to the peach blossom of outdoor cropping, manual adjustment is carried out to the florescence of peach blossom, in full bloom during can making peach blossom advance flowering period to long holidays on National Day, advance flowering period 150 days, and there is good appreciation effect.The present invention is simple and easy to do, cost is low, effect stability, can make peach blossom scenic spot, develop in rural tourism and play a positive role.
