Abstract
The method for resisting retrogression in the course of producing seed bulb of tulip includes the following steps: after it is sowed, covering the surface of the soil with rice straw to reduce soil temperature, it is favorable for delaying senility of tulip plant, after the scape of the tulip plant is extended, removing bud so as to reduce nutrient consumption, it is favorable for growth of underground seed bulb, using phenylurea growth regulator CPPU (N-(2-chloro-4-pyridyl)-N-phenylurea) or adding small quantity of growth regulator containing potassium dihydrogen phosphate and washing powder to treat leaf blade of tulip, when the sunlight is intense, adopting sunshading measure, when one-half of leaf blade of tulip plant is withered, harvesting seed bulb. Said invention can prolong growth period of tulip plant, can inhibit retrogression of seed bulb and implement rejuvenation of seed bulb.
Description
Technical field:
The present invention relates to the degeneration method in a kind of tulip seed balls production, adopt growth regulator to handle the tulip blade, delay plant senesecence, realize kind of a ball rejuvenation, inhibition is degenerated, and belongs to agricultural biotechnologies, especially belongs to Ornamental Plants and Horticulture.
Background technology:
Tulip (Tulipa gesneriana L) is world-renowned flowering bulb.Ball dependence on import always on a large scale from Dutch introducing and planting, has been planted by China since the eighties.Now, China all needs to spend a large amount of foreign exchanges every year from the imported from Holland tulip seed balls, disposable use.For solving the tulip seed balls DOMESTICATION PROBLEM, domestic scholars has been carried out research for many years.
The tulip plant just can sprout growth about 5 ℃, aging death then more than 25 ℃.After the kind ball sows in autumn, need finish necessary low-temp reaction, could bloom at the normal growth in spring through winter low temperature.China's weather and Holland differ greatly, and south is not suitable for the tulip growth fully; North China, northwest, the Northeast's cold in winter, very long, spring is of short duration and dry, and tulip has only very short vegetative period after blooming spring, little, the degeneration of the kind ball of generation.
China can satisfy the requirement of tulip to low temperature in some areas winters, grows again spring, has a moderate climate, favourable tulip growth, can use suitable technological means, delay the aging of tulip blade, thereby prolong the vegetative period of tulip plant, suppress kind of ball and degenerate, reach the purpose of rejuvenation.Had not yet to see the correlation technique report.
Summary of the invention:
The objective of the invention is to defective and actual needs, the degeneration method in a kind of tulip seed balls production is provided, prolong the vegetative period of tulip plant, suppress kind of a ball degeneration, realization kind of a ball rejuvenation at prior art.For realizing such purpose, in the technical scheme of the present invention, employing covers millet straw to reduce ground temperature on the face of land, favourable tulip plant delays senility, and adopts and removes bud to reduce the consumption to nutriment, the ball of advantageously sowing growth, use phenyl ureas growth regulatory substance CPPU (N-(2-chloro-4-pyridine radicals)-N-phenylurea) to handle the tulip blade,, delay leaf senile in conjunction with measure such as plant being shaded, thereby prolong the plant strain growth phase, realize the rejuvenation of tulip seed balls.
Specific operation process of the present invention is:
1, sowing when late autumn, temperature was reduced to 8 ℃ to 16 ℃ left and right sides of daily mean temperature, is carried out the tulip sowing.Carefully peel off bulb brown epidermis during sowing, prevent to hinder root.
2, water,, be beneficial to kind of a ball and take root smoothly if tulip seed balls antecedent soil moisture after planting need water once permeablely.
3, cover millet straw, tulip after planting covers the skim millet straw on the face of land before frost.
4, the flower bud that deflorates after spring, tulip plant scape stretched, is removed bud, in order to novel species ball growth under the nutriment supply place.
5, spray growth regulator is used to contain the CPPU growth regulator of 1ppm～20ppm concentration, or adds the growth regulator spray tulip blade of 0.1% potassium dihydrogen phosphate and 0.05% washing powder again; Spray once again after 2 weeks.
6, shade, its fine sunlight is strong, temperature is more than 25 ℃, and hid with shading screen up at 3 o'clock in afternoon and remove 30% to 70% sunlight the morning 10.
7, results, results kind of ball when tulip plant leaf about 1/2nd is withered.
In the present invention, the face of land covers millet straw can reduce ground temperature, and favourable tulip plant delays senility.Remove bud, can reduce the consumption of the process of blooming, make novel species ball growth under the more nutrition supply place nutriment.The spray growth regulator suppresses leaf senile, can prolong the plant photosynthesis time.Shade and to reduce the blade face temperature, delay leaf senile.These all help expanding of tulip seed balls and rejuvenation.
Embodiment:
Below by specific embodiment technical scheme of the present invention is further described.
Embodiment 1
When 15 ℃ of left and right sides of daily mean temperature, carry out the tulip seed balls sowing.Carefully peel off bulb brown epidermis during sowing, prevent to hinder root.If tulip seed balls is antecedent soil moisture after planting, water once permeablely, and before frost, cover the skim millet straw on the face of land.After tulip plant scape stretched in 1 year, remove bud.The growth regulator that spray contains 8ppmCPPU once sprays same concentration C PPU after spending for 2 weeks again., temperature strong at sunlight is more than 25 ℃ the time, and hid with shading screen up at 3 o'clock in afternoon and remove 30% to 70% sunlight the morning 10.Results kind of a ball when tulip plant leaf about 1/2nd is withered.
Embodiment 2
When 15 ℃ of left and right sides of daily mean temperature, carry out the tulip seed balls sowing.Carefully peel off bulb brown epidermis during sowing, prevent to hinder root.If tulip seed balls is antecedent soil moisture after planting, water once permeablely, and before frost, cover the skim millet straw on the face of land.After tulip plant scape stretched in 1 year, remove bud.The growth regulator (containing 0.1% potassium dihydrogen phosphate and 0.05% washing powder) that spray contains 4ppmCPPU once sprays same growth regulator once after spending for 2 weeks again., temperature strong at sunlight is more than 25 ℃ the time, and hid with shading screen up at 3 o'clock in afternoon and remove 30% to 70% sunlight the morning 10.Results kind of a ball when tulip plant leaf about 1/2nd is withered.
Claims (1)
1, degeneration method during a kind of tulip seed balls is produced, it is characterized in that when 8～16 ℃ of daily mean temperatures, sowing, water once permeable, cover millet straw on the face of land, the plant scape is removed bud after stretching, with the N-that contains 1ppm～20ppm concentration (2-chloro-4-pyridine radicals)-N-phenylurea CPPU growth regulator, or the growth regulator that adds 0.1% potassium dihydrogen phosphate and 0.05% washing powder again sprays the tulip blade, spray once again after two weeks, strong at sunlight, temperature adopts more than 25 ℃ the time shading screen to hide and removes 30% to 70% sunlight, results kind of a ball when tulip plant leaf 1/2nd is withered.
