Abstract

The invention discloses a kind of method promoting Taxus x media to bear fruit, mainly comprise pollen collecting, pollen dissolves and pollinate three steps.By method of the present invention, under the prerequisite ensureing supply plant nutrition, by the extension of the Taxus x media of artificial pollination rate significantly improve, can 70%-90% be reached.

Description

A kind of method promoting Taxus x media to bear fruit

Technical field

The invention belongs to field of agricultural cultivation, be specifically related to a kind of method promoting Taxus x media to bear fruit.

Background technology

Taxus is in dioecious plant, and in natural situation, Taxus x media staminiferous plant is few, only have ten thousand/and several.Therefore, of the right age Taxus x media nature fruit bearing rate is extremely low, and Taxus x media male and female florescence difference is comparatively large in addition, and some female flowers are than more than the late the longest two weeks of male flower, and not synchronously, No kernels or seeds are gathered, as in a year of scarcity to make most of female plant.

Summary of the invention

The technical problem that will solve of the present invention is that Taxus x media staminiferous plant is few, the florescence differs greatly the problem causing fruit bearing rate low.

Technical scheme of the present invention is:

Promote the method that Taxus x media is born fruit, mainly comprise pollen collecting, pollen dissolves and pollinate three steps.

Further, the step of pollen collecting is:

1. gather: collection is bloomed, the petal of male flower and the maturation of blooming of just blooming, be about to, by the male flower of collection and petal spaced apart;

2. post-processing approach is gathered: the male flower of collection or petal adopted the method for Exposure to Sunlight or light-illuminating to accelerate the ripening pollen; The pollen will collected after removing foreign material; Or directly preserve petal according to the florescence of female flower;

3. preserve: pollen or petal are put in refrigerator and preserves, room temperature should be placed in when taking and within lower more than 1 hour, make it to return to normal temperature; Petal recovers to take after normal temperature Exposure to Sunlight or the light-illuminating petal that accelerates the ripening to pop collection pollen;

Further, the method that pollen dissolves is: by weight, in pollen: the ratio of water=1:4000 ~ 10000 is modulated into pollen liquid.

Further, need in pollen liquid to add borax and sugar, addition is by weight: borax 3 ~ 8%, sugar 5 ~ 10%.

Further, the method for pollination is: select fine day or cloudy day, adopts spraying apparatus pollen liquid atomisation to be sprayed onto female taking, the situation of blooming of close observation female flower and florescence, pollinates as required 2 ~ 3 times.

The present invention compared with prior art tool has the following advantages:

By method of the present invention, under the prerequisite ensureing supply plant nutrition, by the extension of the Taxus x media of artificial pollination rate significantly improve, can 70%-90% be reached.

Embodiment

Promote the method that Taxus x media is born fruit, mainly comprise pollen collecting, pollen dissolves and pollinate three steps,

Wherein the step of pollen collecting is:

1. gather: after annual the beginning of spring, at the beginning of 2 months, start Chinese yew staminiferous plant start gradually to enter full-bloom stage, male flower collection can be carried out, collected by hand those bloom, the petal of male flower and the maturation of blooming of just blooming, be about to, by the pollen that gathers and petal spaced apart.

2. gather post-processing approach: be spread out in by male flower on white light paper thinly, upper cover white light paper (light faces down), shines under being put in sunshine, and every 2 hours turn over 1 time, within 1 day, is visible powder; If temperature is lower do not have sunlight, the method that incandescent lamp can be adopted to toast is accelerated the ripening pollen.With the light sieve of sieve, remove foreign material and be placed in Clear glass bottles and jars.Also powder can be become directly to preserve petal according to the flowering time of female flower petal of not being eager to accelerate the ripening.

3. preserve: pollen or petal are put into preserve in temperature 4 degree of refrigerators can more than 20 days, Cord blood is the decline in order to slow down pollen activity.Room temperature should be placed in when taking within lower more than 1 hour, make it to return to normal temperature.Petal recovers Exposure to Sunlight mode can be taked to obtain pollen after normal temperature, if weather reason does not have the sun can pop and see powder with the light-illuminating petal that accelerates the ripening.If the pollen collected in two or three days just is preserved under can being placed in normal temperature.

The method that pollen dissolves is:

1. modulate pollen liquid: at room temperature first get a certain amount of pollen add water (best distilled water) in mass ratio the ratio of 1:4000 ~ 10000 be modulated into pollen liquid.

2. active substance is added: in order to the vigor strengthening pollen improves fertilization rate, can add appropriate borax and sugar in pollen liquid, adding proportion is by weight: borax 3-8%, sugared 5-10%.

The method of pollination is:

Bloom due to Taxus x media female plant and generally bloom late 3 ~ 10 days than staminiferous plant, what climate impact even had reaches more than two weeks, and pollination should select fine day, cloudy day, should start at afternoon about 3:00.

Pollinating method: 1. extensive pollination sprayer spraying pollination, the colored component according to gathering can adopt special manual sprayer, family garden manual sprayer, even equipment of small motor sprayer etc.; 2. medium-scale pollination can adopt manual compression formula water sprager, notes keeping pressure furnishing at any time vaporific; 3. pollination can adopt laboratory/medical manual vial rubber balloon jet pipe on a small scale.The method can be adopted to Potted orchard.

No matter adopting any equipment, by pollen liquid atomisation, so both all should save pollen and reaching maximum coverage area when carrying out artificial pollination.The situation of blooming of close observation female flower and florescence, can pollinate 2-3 time.

Claims

1. promote to it is characterized in that the method that Taxus x media is born fruit, for pollen collecting, pollen dissolve and pollinate three steps, the step of pollen collecting is:

2. post-processing approach is gathered: the male flower of collection or petal adopted the method for Exposure to Sunlight or light-illuminating to accelerate the ripening pollen; Pollen is collected after removing foreign material; Or directly preserve petal according to the florescence of female flower;

The method that pollen dissolves is: by weight, in pollen: the ratio of water=1:4000 ~ 10000 is modulated into pollen liquid, and need in pollen liquid to add borax and sugar, addition is by weight: borax 3 ~ 8%, sugar 5 ~ 10%; The method of pollination is: select fine day or cloudy day, adopts spraying apparatus pollen liquid atomisation to be sprayed onto female taking, the situation of blooming of close observation female flower and florescence, pollinates as required 2 ~ 3 times.
