Abstract
The invention discloses an efficient cultivation method for sonneratia apetala Buch-Ham seedlings. The purpose is to solve the problems that in the forestation initial stage of sonneratia apetala Buch-Ham, the survival rate is low, and the preserving rate is low. The method includes the following steps of seedling cultivation, seedling transplanting and stem and root cutting, and the cultivation method has the advantages that stem cutting and secondary root cutting are performed on the container-grown seedlings of certain specifications in the later stage of sonneratia apetala Buch-Ham seedling cultivation, so that the sonneratia apetala Buch-Ham seedlings are developed in root system, plants are robust, the thickness of stems is increased obviously, and high-quality seedlings good in uniformity can be provided for coast protection forest construction. The seedlings cultivated by the application of the technology can make the original forestation survival rate be improved above 95% from 85%, and the original preserving rate of annual growth sonneratia apetala Buch-Ham can be improved to 90% from 81%. Therefore, compared with the traditional mode that half year growth seedlings of the 40cm-70cm height are adopted for performing forestation, the forestation survival rate and the preserving rate are greatly improved. The technology is particularly suitable for performing mangrove forest forestation on coastal mud flat.
Description
Technical field
The present invention relates to the seedling culture technology in forestry, relate in particular to the seedling culture method of the pagatpat in mangrove plant.
Background technology
Pagatpat (Sonneratia apctala Buch-Ham) is Sonneratiaceae plant, originates in Bangladesh Shen Daben (Sundarban) mangrove area, is high megaphanerophyte, growth rapidly, well developed root system, has bamboo shoot shape respiratory root, is the pioneer tree species of naked beach artificial afforestration.In recent years, the mangrove forest of my the coastal beach in district is subject to different modes, destruction in various degree, causes coastal ecotope increasingly to worsen, and therefore, widelys popularize Coast Mangrove afforestation imperative.Introduce a fine variety pagatpat, be conducive to change the stand structure of coastal beach, make unlined forest structure being changed into multilayer woods structure, for the ecotope that improves coastal beach creates conditions, after pagatpat grows into forest, also can play imperial wind disappear wave, the solid bank of bank protection, beautify the effect of seashore (dike).
China forest-science worker Zheng DS jade tablet in 1985, Chen Huanxiong etc. introduce pagatpat from Bangladesh, are planted in Dong Zhaigang Mangrove Nature Reserves, Hainan, and growth performance is good.1993-2000 again north causes the ground such as Zhanjiang, Shenzhen, Zhuhai, Shantou and Maoming in Guangdong, and growth performance is also good, all can normally blossom and bear fruit.But introduce a fine variety in process in above-mentioned area, the outplanting rate of artificial breeding is still lower, and as the introducing a fine variety in seedling growth test of Zhanjiang, outplanting rate on average only has 750 strains/kilogram seed (14.41 grams of thousand grain weigths), and all freeze to death 1996 and nursery stock in 1998, within 1999, major part is freezed to death.Find in introducing a fine variety process above-mentioned, the pagatpat seedling afforestation effect of pagatpat artificial culture is unsatisfactory, be mainly manifested in afforestation after initial stage survival rate unstable, be vulnerable to the destruction of the factor such as tidewater, seashore animal.And pagatpat Cold resistance is poor, survival rate is subject to weather effect larger, has directly affected the survival rate of afforestation and the storage rate in forest land.
Summary of the invention
The object of this invention is to provide a kind of pagatpat seedling culture method efficiently, become seedling percent, problem that storage rate is low to solve the mangrove plant pagatpat afforestation initial stage, reach efficient afforestation object.
The seedling culture technology of the pagatpat that the present invention proposes, comprises the steps:
(1) cultivating seedlings
Obtain pagatpat seedling by cultivating seedlings;
(2) seedling replanting
Selection grows sprigging that 6 true leaves or height of seedling reach 6-8cm in container;
Transplant and preferably carry out at the cloudy day, avoid high light, high temperature to make seedling dehydration death, the preferred nutritious bag of described container, the specification of nutritious bag is preferably 10 × 13cm, and matrix formulations is preferably: red soil (table soil) 40%+ macerates ripe cow dung 20%+ farmyard manure 20%+ thin sand and soil 17%+ superphosphate 3%;
(3) cut bar and be completely cured
1. be completely cured for the first time
In the time that in container, pagatpat seedling reaches 40-70cm, the processing of being completely cured, again moves and compiles seedling the container seedling of same batch;
The growth of pagatpat seedling rapidly, in the time that in container, pagatpat seedling reaches 40-70cm, the processing of being completely cured, to promote root growth, the container seedling of same batch is again moved and compiles seedling, the part root system under can breaking in depth, promote lateral root to sprout, although in a short time the growth of plant is had to certain influence, can promote root growth, nursery stock stalwartness, improve the survival rate in later stage;
2. cut bar and secondary is completely cured
Cut bar to highly exceeding pagatpat seedling in the container of 1m, cut off the first half of plant cane with secateurs, notice that clip is level and smooth, side shoot or blade are suitably pruned, and base portion retains 60-70cm, the newly organized seedling of laying equal stress on, carry out secondary and be completely cured, preferably the cloudy day operates;
Preferably 40-60 days before afforestation, cuts bar and secondary is completely cured, and side shoot or blade are suitably pruned, to reduce transpiration.
3. cut the management after bar
After pagatpat seedling cuts bar and secondary and is completely cured in container, strengthen moisture, illumination and extermination of disease and insect pest work, control rich water uses, and after section bar, in 1-2 week, suitably shades, and avoids burning sun and is exposed to the sun, and note keeping basin soil moistening, hot weather can carry out blade spray, after section bar, sprays immediately bactericide, prevents and treats disease and occurs, every 1-2 week regularly sprays bactericide afterwards, until go out garden.
Bactericide preferable methyl topsin or tpn.
Compared to existing technology, the invention has the advantages that:
1, adopt at seedling fostering later stage bar, the technology of being completely cured of cutting, cut bar to highly exceeding pagatpat seedling in the container of 1m, and priority is carried out the processing of being completely cured for twice, pagatpat seedling well developed root system, robust plant, cane are increased obviously thick, improve resistance, can be coast protection forest structure provides uniformity good high-quality seedling.
2, adopt the popularization and afforestation that cuts bar, the technology of being completely cured and carry out at coastal beach pagatpat in the present invention, survival rate can be increased to more than 95% by original 85%, the storage rate of 1 year above pagatpat woods of life is increased to 90% by original 81%.Therefore, afforest with respect to the seedling of the annual 40-70cm height of traditional employing, greatly improved afforestation survival rate and retention rate, this technology is particularly useful for the Mangroves of coastal beach.
Embodiment
With embodiment, the invention will be further described below, but the present invention is not limited to these embodiment.
