Description

Bionic double-protection seedling technology for taxus chinensis var mairei

Technical field

The present invention relates to a kind of southern enqlish yew seedling growing process, especially bionic double-protection seedling technology for taxus chinensis var mairei, belong to the medicinal material field of planting.

Background technology

Southern enqlish yew (Taxas mairei) has another name called beautiful Chinese yew, belongs to the taxaceae aiphyllium, and the four seasons are dark green bright-coloured.Southern enqlish yew is the indigenous tree species of China's preciousness, and main star is rare to be distributed in place such as China south of the River, is the ancient species that quaternary glacier carries over, and is the one-level wild plant of special-protection-by-the-State.Its not only tree-like grace, leaf, really very beautiful lovely, and have stronger stain resistance, can absorb the characteristics of many harmful micronic dust particles in the urban atmosphere, we can say that whole body is precious, is multi-purpose a kind of extremely promising popular seeds such as collection afforestation, medicine extraction.Its, leaf, skin, root, fruit etc. contain anticancer effective ingredient " taxol "." taxol " is one of best medicine of treatment metastatic oophoroma and breast cancer, simultaneously lung cancer, cancer of the esophagus also had significant curative effect." taxol " is the famous and precious medicine of generally acknowledging on the present international market, and price is much more expensive than gold.Scientist discovers can extract 1 gram " taxol " from 3 kilograms of bark of Ramulus et folium taxi cuspidatae, produce " taxol " in the world per year less than 300 kilograms, and annual requirement reaches more than 3,000 kilograms in recent years, so southern enqlish yew has the title of " plant gold ", in great demand.Therefore, strengthen energetically the southern enqlish yew resource cultivation and development and use development potentiality very big.At present, the southern enqlish yew natural resources are very deficient, and the southern enqlish yew artificial breeding is in great demand.But it is backward in technique that traditional outdoor rearing seedling-growing method exists, the low obviously deficiency that waits of the planting percent of growing seedlings.How when stepping up to protect southern enqlish yew germ plasm resource, further reduce the production cost of growing seedlings, improve seed germination rate, emergence rate, planting percent, cultivating the high quality seedling supply the market has become people's active demand.The present invention is in the practical experience of growing seedlings for many years, biological property and ecological characteristics according to southern enqlish yew, break through traditional seedling-cultivating method, " the bionical attitude double-protection seedling technology " that sum up and invented fast growth, the rate of growing seedlings is high, thus finished the present invention.

Summary of the invention

The object of the present invention is to provide a kind of bionic double-protection seedling technology for taxus chinensis var mairei, its production cost of growing seedlings is lower, and seedling growth is fast, and quality is good, goes out a mu rate height, and more traditional open country is grown seedlings and increased production 30-40%, and qualified nursery stock reaches more than 80%.

For achieving the above object; the main feature of a kind of bionic double-protection seedling technology for taxus chinensis var mairei of the present invention is; after the planting seed of putting in order the poison that will disappear in the ground, garden of having sterilized, lid are planted; accomplish fluently at nursery lot immediately and protect cool canopy; and in time cover planting bryophyte on the seedbed; build an imitative natural ecological environment, the normal development of protection seedling, growth, thus reach speed life, high-quality, aim of high yield.Its concrete technical essential is:

1, whole soil sowing.Southern enqlish yew sowing bed surface will be done smoothly, and the top layer soil block is in small, broken bits, and the yellow soil of pad lid layer 3 cm thicks; Use wide 6-8 centimetre again, long 1.5 meters flitch is pressed into drill furrow on the seedbed, and dark about 1 centimetre, bar is apart from 10 centimetres; Seed centimetre carries out " product " font by duplicate rows, spacing in the rows 3-5 to be put, and covers seed, thick about 0.5 centimetre with the mountain ash that sieves then.

2, liver moss covers.After planting bed surface is all covered with liver moss; Spill water then, make liver moss be adjacent to bed surface, unlikelyly blown off by wind.

3, in time protect shade.After planting should comprehensively immediately protect shade, cover with the shade net kid.

The invention has the beneficial effects as follows that seedling growth is fast, quality is good, the emergence rate height, and seedling cost is low.The present invention will play positive progradation to protection, breeding and the development of southern enqlish yew and similar rare tree.

Embodiment

Further set forth beneficial effect of the present invention below in conjunction with embodiment.Adopt the technology of the present invention method to cultivate the southern enqlish yew nursery stock, 24 centimetres of annual average heights of seedling, 0.23 centimetre of leading thread, average per 666.7 square metres of product seedlings reach 8-10 ten thousand strains, grow seedlings than traditional open country and increase production 30-40%, and qualified nursery stock reaches more than 80%.The bionic double-protection seedling technology for taxus chinensis var mairei concrete grammar is as follows:

1, whole soil sowing.Southern enqlish yew sowing bed surface will be done smoothly, and the top layer soil block is in small, broken bits, and the yellow soil of pad lid layer 3 cm thicks; Use wide 6-8 centimetre again, long 1.5 meters flitch is pressed into drill furrow on the seedbed, and dark about 1 centimetre, bar is apart from 10 centimetres; Seed centimetre carries out " product " font by duplicate rows, spacing in the rows 3-5 to be put, and covers seed, thick about 0.5 centimetre with the mountain ash that sieves then.Must guard against blocked up, otherwise, plant that the shell arch is not unearthed and dead.

2, liver moss covers.After planting bed surface is all covered with liver moss; Spill water then, make liver moss be adjacent to bed surface, unlikelyly blown off by wind.Liver moss vitality is strong, as long as suitable trickle is preserved moisture, will grow the bed surface lid full very soon.When southern enqlish yew is unearthed, from the liver moss slit, come outbreak out, exactly like the upgrowth situation that comes up under the southern enqlish yew seed production stand.The benefit that liver moss covers is: 1. protect ground, prevent from too fast generation day of burning sun intensification to burn.2. prevent that heavy rain from spattering mud, stain seedling stem and blade, in a single day seedling is stained with mud, will stop up pore, causes undergrowth or death.3. preserve moisture, be incubated, can prevent day non-irrigated, a freezing and soil compaction, make soil often be in moistening rarefaction.But must be noted that 2 points: at first will could use this way protecting under the shady condition, because of after nursery stock is unearthed, if meet high temperature more than 30 ℃, the seedling stem is too tender, shone heat easily liver moss burn and produce damping off.Secondly when nursery stock is about to be unearthed, when liver moss is too many in the seed furrow, suitably remove a part, only stay and be close to face of land one deck, in case cross wet with day burn.

3, in time protect shade.Because southern enqlish yew seedling stage is well-grown under shady wet environment condition only, be difficult to adapt to the environmental condition of field seedling raising, so southern enqlish yew is grown seedlings and protected shady and other seeds to grow seedlings different be after planting should comprehensively immediately protect shade.Cover with the shade net kid.Protect shade as untimely, dehydration in the time of might making the seed of sowing run into diastrous weather and can not germinateing, or germinate that die with regard to dying young when being unearthed can not Cheng Miao.Because about ground, exposed garden in summer surface temperature was up to 50 ℃, temperature was then low 10-12 ℃ under cool canopy.Usually under normal climatic environment condition, after planting protect shady protection ratio immediately and do not protect shady emergence rate and want high more than 30%, in addition higher, and it is neat to germinate.In extreme weather environment, do not protect shady growing seedlings sometimes and cause being annihilated.As 1992 Xinning County, Hunan Province woods section the nursery in; 2 mu of southern enqlish yews had been educated at that time; in emerge in April several days; the inventor is because of travelling outside; because continuous four days fiery south wind brushes and Exposure to Sunlight, protect in measures such as not implementing to protect the Yin Hegai liver moss, cause then Chinese yew seedling almost to be failed; suffer heavy losses, lesson is deep.
