Description

The technology of a kind of high-yield and high-quality seedlings growing of foreign pine tree

The present invention relates to the technology of the high-yield and high-quality seedlings growing of a kind of foreign pine tree (torch pine, wet-land pine tree).

The present invention is development and coming on the basis of forest seedling growth method at present commonly used, current foreign pine tree grown seedlings three kinds of methods, i.e. conventional method, nutrition bowl method and bud transplantation of seedlings method; Adopt conventional method to educate the foreign pine tree seedling, percentage of seedgermination is low, it is inconsistent to emerge, seedling growth is unstable, and it is 1.0-1.2 ten thousand strains that the per kilogram seed produces the seedling amount; With the nutrition bowl then complicated operation of growing seedlings, it is 1.6-2.0 ten thousand strains that the per kilogram seed produces the seedling amount; Adopt bud transplantation of seedlings method to grow seedlings, not only complicated operating process is subjected to climatic effect also bigger during sowing, and the per kilogram seed produces the seedling amount and also has only 1.6-2.0 ten thousand strains, and it is low that these methods all have the seedling of producing amount jointly, defectives such as seedling quality is poor, seedling cost height.

In view of the foregoing, task of the present invention is the new technology that creates a whole set of foreign pine tree vernalization, sows, grows seedlings, this technology is simple and easy to do, and practical, seed produces seedling rate height, can reduce the seed consumption, save cost, and seedling amount height is produced in the nursery, Miao Zhihao, and general per kilogram seed production can reach 2.8-3.0 ten thousand strains, produce the seedling amount than conventional seedbed system and improve 1.5 times, grow seedlings than nutritive cube and bud transplantation of seedlings and produce seedling and improve 0.53 times.

The purpose that the present invention proposes is finished like this: when pine was grown seedlings abroad, we had adopted normal temperature lamination germination hastening method in the seed chamber, to break the foreign pine tree Seed Dormancy phase; And setting out to adopt when growing seedlings at the mycorhiza association of foreign pine tree tool and the growth characteristics of itself uses sufficient that base manure, band phosphorus are sowed, optimum period is sowed in right amount, topped anti-heavy rain is hindered seedling, and gradation in time removes topped thing, use the seeding and seedling raising technology that fenaminosulf is prevented and treated disease and the moisture management way of doing, wet, controlling at different seedling stages after removing topped thing.The vernalization of normal temperature lamination is promptly at the beginning of southern 3 months by the end of February in the so-called seed chamber, with warm water medicament seed soaking 24 hours, taking out seed then mixes seed and damp sand with kind of a ratio of 1: 4 of sand weight ratio, to plant sand again and put into container, this container is put the indoor of ventilation, drying, no sunlight direct projection, the no plague of rats, stirred once, and remain that kind of sand is moistening can not to be as the criterion by ponding every 3-5 days, continuity vernalization just can be selected good weather and sow in urging to 45-65 days like this.

The present invention has simplified original seedling-cultivating method, normal temperature lamination germination accelerating method and use sufficient that base manure, band phosphorus are sowed, optimum period is sowed in right amount, topped anti-heavy rain is hindered seedling, gradation in time removes topped thing in the seed chamber, spray the seeding and seedling raising technology that fenaminosulf is prevented and treated disease and the moisture management way of doing, wet, controlling at different seedling stages after removing topped thing, this cover technology is simple and easy to do, practical, can reduce sowing quantity and produce seedling rate height, Miao Zhihao, seedling cost and economize, and can make to produce the seedling rate and produce seedling 1-2 ten thousand strains by general per kilogram and bring up to 2.8-3.0 ten thousand strains.

Concrete grammar of the present invention is provided by the following examples:

In China south at the beginning of by the end of February to 3 months, it is some to get clean natural water, be heated to 45 ℃, add millesimal topsin agricultural chemicals then and stir, pour stand-by foreign pine tree seed into the twenty four hours of soaking seed in this medicine again, it is some to get free sand again, add clear water be transferred to hand firmly pinch sand can be agglomerating, do not end but do not drip, the foreign pine tree seed that will soak twenty four hours then takes out drop once, mix than 1: 4 ratio of sand (weight ratio) in seed again, and the kind sand that mixes placed in the clean container (cylinder or tub all can), hold THICKNESS CONTROL at 30-50 centimeters, the container that fills kind of sand is placed on ventilation, dry, the sunlight direct projection is less than container, the no plague of rats indoor stirred once every 3-5 days later on, and to need to drench nature water some as too dried, keeping kind of sand moistening, but should grasp in the container not till the ponding.In 45-65 days vernalization process, note grasping all the time the humidity and the temperature of kind of sand, temperature and room temperature are consistent, be higher than room temperature as kind of a sand temperature, kind of sand humidity is too high, should will plant sand and spread out in indoor ground, and that says previously for another example when cooling almost equally carries out lamination vernalization at once.Sowing generally at the beginning of mid-April to 5 month (be vernalization after 45 days to 65 days during this period of time in) can select good weather and sow, seeding quantity requires to decide on seed germination rate and cleanliness, generally be percentage of seedgermination about 90%, the seed of cleanliness about 99%, torch pine can be broadcast 1.5-2 kilogram, wet-land pine tree 2.0-2.5 kilogram by mu; The nursery lot fertilising requires heavy dressing base manure, and requires to sow with the fused calcium magnesium phosphate seed dressing, and the visual seedling growth situation of topdressing takes the circumstances into consideration to use; The moisture management principle of nursery stock is: seedling growth is in earlier stage to carry out moistening irrigation in draining, mid-term, later stage is according to the nursery stock production situation, urge the control seedling growth with moisture content, general moisteningly promote seedling growth, suitably drying can make seedling growth slow down, the nursery stock that goes out different size by directive breeding so on request.Simultaneously seedling stage, it is topped that available crop stalk carries out seedling ground in order to alleviate the harm of heavy rain to seedling, will divide when removing topped thing and carry out for three times, and requirement all will spray the diseases prevention of the millesimal fenaminosulf aqueous solution when removing topped thing at every turn.
