Description
Technical field
The invention belongs to the arboriculture field, relate to a kind of Chinese photinia leaf and urge the red method autumn.
Background technology
Chinese photinia is evergreen shrubs or dungarunga, likes the weather of warm and moist, has again cold-hartliness, its happiness light anti-shade again, and not tight to the soil requirement, rudiment power is strong, and anti-pruning has certain resistance to flue dust and toxic gas.The main product Yangtze river basin and areas to the south, the Qinling Mountains, there is a small amount of cultivation North China, Chinese photinia tree crown rounding, blade light is green, and the early spring, tender leaf was purplish red, and spring end is spent a point in vain, autumn days, haw was innumerable, was rich in ornamental value, thus Chinese photinia oneself become indispensable ornamental tree species in Landscape.Due to the Chinese photinia fruit easily by birdseed, so Chinese photinia autumn and winter season color show slightly dull, the special North of Huai River of evergreen species rareness in the winter time, have green or the colorful one seeds particularly to treasure.The present invention is on Chinese photinia tree, selects branch to carry out ring-type and carves wound, impels the pigment of carving the position, traumatic part to occur by green to red variation, reach ten thousand green therefrom one red, the landscape effect that Chinese photinia was set in autumn and winter season is more rich and varied and charming.
Summary of the invention
The present invention is to provide a kind of Chinese photinia leaf and urges the red method autumn.
The technical solution used in the present invention is as follows:
A kind of Chinese photinia leaf is urged the red method autumn, comprises the steps:
(1) expect festivals or holidays in the fall (being generally National Day and the mid-autumn) first 45～55 days, select the plant periphery to be no more than the annotinous branch of 50 centimeter length, in branch base position ring-type, carve wound;
(2) carve wound imposes 2～3 0.5%～1% concentration Alkitrate in January later;
(3) carve wound and will regularly water in January later, keep tree surrounding soil moisture state.
In step (1), described branch base position ring-type is carved wound, carve hinder area be the branch girth 1/4～1/3,0.3 centimetre of width, the degree of depth reach xylem.
In step (2), described potassium nitrate KNO
3belong to binary compound fertilizer.The total content of nutrient for plants potassium, nitrogen can reach 60% left and right.
Imposing described in step (2) watered and executed in the soil around trunk with the Alkitrate configured.
In step (2), described 0.5%～1% Alkitrate is the multiple of potassium nitrate fertilizer dilute with water.
Beneficial effect: a kind of Chinese photinia leaf of the present invention is urged the red method autumn, solved the poor deficiency of appreciation effect that Northern Area of Huaihe River autumn and winter season Chinese photinia tree dull coloring is brought, make the Chinese photinia leaf can be according to people's will, the beautiful color that bursts forth, allow people enjoy the beautiful landscape that the Chinese photinia color change is brought in the festive occasion.
Embodiment:
According to following embodiment, the present invention may be better understood.Yet, those skilled in the art will readily understand, embodiment is only for the present invention is described, and should also can not limit the present invention described in detail in claims.
Embodiment 1:
In early August, 2010, at (Jiangsu Province's Yixing City), select Chinese photinia 198 strains of life in 5～10 years, select the plant periphery to be no more than the annotinous branch of 50 centimeter length, carve wound in branch base position ring-type, carve hinder area be the branch girth 1/4～1/3,0.3 centimetre of width, the degree of depth reach xylem, then regularly water, keep the tree surrounding soil to be moisture state, during water secondary in the soil of executing at trunk on every side with 1% Alkitrate.After two weeks, carve the position, traumatic part and grow successively callus, the leaf color also starts slowly to change, and late September carves and hinders the branch leaf and can become redness, reach ten thousand green therefrom one red, make people enjoy the beautiful landscape that the Chinese photinia color change is brought on National Day.
