Abstract

The present invention relates to the technology of promoting to bloom and fruit, and features that it provides the technological route including the first inhibiting the fast growth of sabina vulgaris in its physiological blossom bud initiating period and the subsequent initiation of blooming gene expression. Specifically, the leaves are first sprayed with cycocel solution in 50 ppm concentration to suppress their nutritive growth and then sprayed with mixed GA4 and GA7 solution in 5 ppm concentration after 20-30 days to start blooming gene expression in the blossom bud initiating period. The solution is controlled in pH 4.5-6.5 for optimized effect.

Description

The artificial technology that promotes that Sabina vulgaris blossoms and bears fruit

Sabina vulgaris (Sabinavulgaris) has another name called fork garden cypress, smelly cypress etc., Cupressaceae, garden cypressCypressus, the evergreen needle shrub that crawls.Mainly be distributed on mountain region, loess hill and the sand ground of the continental arid in temperate zone, semiarid region.Sabina vulgaris with its wide accommodation, be thick with leaves, constantly enlarge association, adapt to the drought desert environment for a long time, become that arid, semiarid region are checked winds and fixed drifting sand, the fine tree species of water and soil conservation, play an important role to improving arid biogeographic zone environment and prevent desertification.Caused domestic and international expert's common concern in recent years.Yet under native state, the Sabina vulgaris trophophase is long, and seed quality is poor, and seed germination rate is low, and the seedling planting percent is low.Speed gives birth to that excellent strain branches and leaves are luxuriant, well developed root system, the ability of fixing the sand are strong, but fast natural disposition shape suppresses to blossom and bear fruit, and in evening productive phase, breeding output is extremely low, greatly influences planting site growth potential and improved variety process.Therefore, the present invention reaches the purpose that promotion Sabina vulgaris early flowering is solid, improve seed vitality by the relation of growth of artificial regulatory Sabina vulgaris and reproduction.Through this technical finesse, the Sabina vulgaris that life in 2 years is above just can blossom and bear fruit.This not only has great importance to natural regeneration, the succession of community, and the regulation and control theoretical research of blooming of Sabina vulgaris is also had crucial meaning, makes Sabina vulgaris bring into play bigger potentiality at artificial afforestration, water and soil conservation, desertification control.Realize fast growing, greatly improve its economy and ecological benefits.

This technology is made a start the phase at Sabina vulgaris bud physiology, suppress earlier to nourish and grow, back regulation and control floral genes, leaf primordium is transformed to flower primordium, the position of former leave bud is transformed into bud morely, realize the solid of breeding and high yield, reach in advance and blossom and bear fruit, and good hereditary quality is passed to follow-on purpose.

According to this theory, realize that the regulation and control step is as follows:

1. adopt 50ppm chlormequat spray solution to handle its blade according to claim 1., suppress nourishing and growing of metasequoia.

2. after the inhibition metasequoia nourished and grew 20～30 days, use 5ppmGA again ₄And GA ₇Mixed liquor sprays and handles blade, starts floral genes and expresses, and promotes that leaf primordium transforms to flower primordium.

3. above-mentioned treatment fluid pH value all is controlled between 4.0～5.0, to obtain the optimization process effect.

4. according to claim 1., above-mentioned processing is all carried out in the Sabina vulgaris bud physiology phase of making a start, and as suppressing growth process in Beijing at the beginning of 6 months, starts floral genes at the beginning of about 7 months and expresses processing.

Application cost of the present invention is cheap, easy to operate, and productive potential are big, ecological and economic benefit height.

Claims

1. the present invention relates to the artificial technology of blossoming and bearing fruit of promoting of a Sabina vulgaris, it is characterized in that the make a start plant of phase of bud physiology is taked to suppress earlier to nourish and grow, the back starts the technology path that floral genes is expressed.

2. just can carry out this technical finesse according to 1. pairs of 2 years above Sabina vulgaris of life of claim.

3. adopt 50ppm chlormequat spray solution to handle blade according to claim 1., suppress it and nourish and grow.

4. according to claim 1., claim 2. suppress Sabina vulgaris nourish and grow handle 20～30 days after, use 5ppmGA again _4,7Spray and handle blade, start floral genes and express.

5. according to claim 1., the above-mentioned treatment fluid pH value of claim 2. and claim 3. all is controlled between 4.0～5.0, to obtain the optimization process effect.

6. according to claim 1., above-mentioned processing is all carried out in the China fir ground Bai Huaya physiology phase of making a start, and as suppress the processing that China fir ground cypress nourishes and grows at the beginning of 6 months in Beijing, starts the processing that floral genes is expressed at the beginning of about 7 months.
