Abstract

The invention discloses a method for promoting fruit bearing of Taxus media. The method mainly includes the three steps of pollen collection, pollen compounding and pollination. With the method provided in the invention, under the premise of ensuring plant nutrient supply, the fruit bearing rate of Taxus media subjected to artificial pollination can be significantly enhanced, and can reach 70%-90%.

Description

A kind of method that promotes that Taxus x media is born fruit

Technical field

The invention belongs to the agricultural planting field, be specifically related to a kind of method that promotes that Taxus x media is born fruit.

Background technology

Taxus is in dioecious plant, and in natural situation, the Taxus x media staminiferous plant is few, only has ten thousand/several.Therefore, of the right age Taxus x media nature fruit bearing rate is extremely low, and the Taxus x media male and female florescence differs larger in addition, and some female flowers are than more than male flower the longest late two weeks, not synchronous, and 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 the Taxus x media staminiferous plant is few, the florescence differs greatly and causes the problem that fruit bearing rate is low.

Technical scheme of the present invention is:

A kind of method that promotes that Taxus x media is born fruit, mainly comprise pollen collecting, pollen three steps that dissolve and pollinate.

Further, the step of pollen collecting is:

1. gather: gather male flower and the ripe petal blooming, just bloom, be about to bloom, by male flower and the petal spaced apart gathered;

2. gather post-processing approach: the male flower of collection or petal are adopted to the method for Exposure to Sunlight or the light-illuminating pollen that accelerates the ripening; Remove after foreign material the pollen of collecting; Or directly preserve petal according to the florescence of female flower;

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

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

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

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

The present invention compared with prior art has following advantage:

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

Embodiment

A kind of method that promotes that Taxus x media is born fruit, mainly comprise pollen collecting, pollen three steps that dissolve and pollinate,

Wherein the step of pollen collecting is:

1. gather: start the Chinese yew staminiferous plant at the beginning of 2 months and start gradually to enter full-bloom stage after annual the beginning of spring, can carry out the male flower collection, manual those male flowers of blooming, just bloom, being about to bloom and the ripe petal of gathering, by pollen and the petal spaced apart gathered.

2. gather post-processing approach: male flower is spread out on white light paper thinly, and upper cover white light paper (light faces down), be put under sunshine and shine, and turn over 1 time in every 2 hours, within 1 day, is visible powder; There is no sunlight if temperature is low, can adopt the method for the incandescent lamp baking pollen that accelerates the ripening.With the light sieve of sieve, remove foreign material and be placed in Clear glass bottles and jars.Also can become powder directly to preserve petal according to the flowering time of the female flower petal of not being eager to accelerate the ripening.

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

The method that pollen dissolves is:

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

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

The method of pollination is:

Because the Taxus x media female plant is bloomed and is generally bloomed late 3～10 days than staminiferous plant, the climate impact even has reach two weeks more than, pollination should be selected fine day, cloudy day, should start in afternoon 3:00 left and right.

Pollinating method: 1. atomizer spray pollination for extensive pollination can adopt special manual sprayer according to the colored component gathered, family garden manual sprayer, even equipment of small motor sprayer etc.; 2. the medium-scale pollination can adopt manual compression formula water sprager, notes keeping at any time the pressure furnishing vaporific; 3. pollination can adopt laboratory/medical manual vial rubber balloon jet pipe on a small scale.Can adopt the method to potted plant seedling.

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

Claims
