Abstract
The invention discloses a method for growing seedlings of schima superba seeds, comprising the technologies of collecting and storing seeds, selecting and treating a garden land, treating the seeds, carrying out seeding, performing seedling management, applying fertilizer and the like. In the invention, a low-temperature cold store (the temperature of the cold store is controlled to be 3 DEG C) is adopted for storing the schima superba seeds. Therefore, the respiration intensity of the seeds is reduced; the energy consumption of the seeds is reduced; and the viability of the seeds is kept. Accordingly, the sprouting rate is improved; the supply and demand problem in on-year and off-year of the schima superba seeds is effectively solved; and the method has important practical significance. In the invention, seed beds are subjected to disinfection treatment before seeding so that the rate of emergence and survival of the seeds can be effectively improved, and the lignification of the seedlings can be effectively promoted by additional fertilizer application in the later period. The method plays an important role in breeding high-quality seedlings.
Description
Technical field
The present invention relates to a kind of method of nursery of plant of theaceae seed, particularly a kind of method of Schima superba seed seedling-raising.
Background technology
Schima superba, another name He Shu, lotus wood, Theaceae aiphyllium is the deciduous species of China's preciousness, and the yielding timber plantationsion that Yangtze river basin areas to the south of Ye Shi China is main belongs to national second class protection seeds.The height of tree reaches 30m, diameter of a cross-section of a tree trunk 1.3 meters above the ground 1m, and the life-span reaches more than 100 years, is more common in low mountains and hills, normal with masson pine or the Evergreen Broad-leaved Tree Species such as Lauraceae, Fagaceae is mixed gives birth to.Schima superba trunk is logical straight, and tree crown is dense, and blade is thicker, and keratin is fire-resistant, and rudiment power is strong.Schima superba withered fallen leaf is many, can improve soil, increases soil fertility, has and conserve water and soil, the function of water conservation, be suitable for the cultivation of South Fujian Province, is the pioneer tree species building water conservation forest and Forest Belts of Biological Fire Prevention.Schima superba nursery stock tool deep-rootedness, its well developed root system, strong to soil suitability, the soil afforestation of every arid acid red soil, yellow earth, red-yellow soil, yellowish soil all can grow.Its wood usage is wide, can make furniture, revolve the excellent material of plane joiner, peeler log, national defence material and other industrial cut stock.Bark, leaf, containing tannin, can extract tannin.
Because Schima superba seed germination is difficult, germination rate is low, causes certain difficulty to nursery work, bring certain impact to production of forestry.Schima superba solid biennial bearing phenomenon is fairly obvious, and off year, seed was very in short supply, and thus seed storage has just become to produce upper a great problem.Autumn and winter gather after Schima superba seed, adopting normal temperature laboratory storage, can only depositing to surviving the winter.The speed that after surviving the winter, Seed Vitality is lost, generally next year percentage of seedgermination is very low, almost loses germinating capacity.In order to extend the storage period of Schima superba seed, carry out normal temperature laboratory storage and deepfreeze and test and be necessary, and it is imperative to propose the seedling growing processs such as the feasible Schima superba seed collection of a whole set of science, storage, vernalization, sowing and management.
Summary of the invention
A method for Schima superba seed seedling-raising, is characterized in that, comprises the following steps:
1), seed collection and seed storage: in late October, when finding that Schima superba capsule slightly splits, oneself is ripe to show seed, should collect seed in time, and then the capsule under adopting is placed on airing under the sun, allow it all split, seed will drop out in shell.Installed by collected seed cloth bag, low-temperature cold store (storehouse temperature control is at 3 DEG C) is preserved;
2), ground, garden is selected and process: select physical features smooth, draining is convenient, favourable irrigation, and soil layer is deep, and fertile soil, moistening yellow-red soil make ground, garden.Turn over ground, rake garden before sowing 1 time, use sufficient base manure, every 667m
2discharge cake fertilizer 2000kg, composite fertilizer 200kg, turn over rake and mix together with soil, nursery soil is loosened careful.And nursery soil is carried out disinfection, generally doubly spray (or fenaminosulf 100 times of liquid of 55%) with topsin 1500-2000.Be control soil insect (mainly cutworm lotus mole cricket), with the 70% Furadan 4.5-5.5kg/ even seedbed that is spread on per mu simultaneously;
3), seed treatment: adopt the seed soaking mode that warm water and hormone solution combine.Schima superba seed first uses 0.5% potassium permanganate solution disinfection, again with the warm water of 50 DEG C and bond quality concentration is 30mg/100mL Gibberellins solution repeatedly soaks seed 3 times, each 12h, seed soaking is placed on the vernalization of warm place, can sow when seed has about 20% to germinate;
4), sow: Schima superba adopts and broadcasts sowing.Broadcast sowing and generally carry out when spring next year.Seed is evenly sprinkling upon on seedbed, and covers rare earth 1-2cm, then use watering can trickle one time, cover weeds;
5), seedling management and fertilising: water management, weeding, topdress, thinning.Irrigation times is determined according to weather and soil moisture situation, and the general 5-7d of continuous sunny fills with 1 water, when meeting ground, rainwater excessive or garden ponding, answers drainage waterlogging prevention.Under suitable temperature, humidity, Schima superba seed is unearthed through about 26d, and about 32d all sprouts, and now should, in being removed by lid grass at dusk, note preventing mouse, unfirmly closing food and damaging seedbed simultaneously.Seedbed uprooting weed should select after the rain or the cloudy day pour water after carry out.Answer SC during uprooting weed, seedling root soil can not be loosened.Water in time after uprooting weed, make by the nursery soil consolidation loosened, in order to avoid cause nursery stock dead because of ventilative.For ensureing Schima superba nursery stock normal growth, must apply fertilizer to nursery stock, accomplishing that thin fertile duty is executed, from thin to thick.Get final product thinning after-culture as nursery stock height about 10cm, every square metre retains 50-60 strain in strong sprout, and just start final singling as height of seedling 10-15cm, every square metre can retain 50-60 strain in strong sprout.To height of seedling 60-80cm, about ensureing the strain of every square metre of product seedling amount 50.
Further, described method, is characterized in that, described seed storage takes low-temperature cold store (storehouse temperature control is at 3 DEG C) to preserve.
Further, described method, is characterized in that, fertile soil is selected on described ground, garden, moistening yellow-red soil makes ground, garden.
Further, described method, is characterized in that, described nursery soil topsin 1500-2000 doubly sprays, and (or fenaminosulf 100 times of liquid of 55%) carry out disinfection.
Further, described method, is characterized in that, described seed treatment takes 0.5% potassium permanganate solution, 50 DEG C of warm water, mass concentrations are that the mode that 30mg/100mL Gibberellins solution combines is soaked seed repeatedly.
The present invention takes low-temperature cold store (storehouse temperature control is at 3 DEG C) to preserve Schima superba seed, both the respiratory intensity reducing seed had been conducive to, the energy ezpenditure of seed itself can be reduced again, keep its vitality, thus improve germination, efficiently solve the supply and demand problem in Schima superba seed size year, have important realistic meaning.Can effectively improve percentage of seedgermination and survival rate to seedbed disinfection prior to seeding before the present invention sows, manuring late effectively can promote the lignification of nursery stock, for promoting that the seedling cultivating high-quality serves vital effect.
