Abstract
The invention relates to a rubber tree seed storage method. The method includes: selecting normal seeds with water content more than 20%, soaking the selected seeds in carbendazim solution for disinfection, and then taking out the seeds for airing; taking fine river sand, and spraying the carbendazim solution for disinfection prior to airing; spreading a layer of the fine river sand at the bottom of a storage box, spreading the rubber tree seeds on the fine river sand, taking seed storage mixture, enabling the seed storage mixture to absorb water, and then spreading the mixture on the seeds; spreading the rubber tree seeds above the seed storage mixture, and then spreading the seed storage mixture; and by the analogy, spreading the fine river sand on the upper side of the seed storage mixture in the top layer, and storing at the temperature of 20-27 DEG C and in the relative humidity of 40-60%. The rubber tree seed storage method is simple in process, a large quantity of the rubber tree seeds are stored in a short period by the aid of the processes of seed selection, disinfection, storage, storage room temperature and humidity control and the like, the rubber tree seeds can be provided all the year around, a technical guarantee is provided for industrialized production of the rubber tree seedling budding and culture technology, and the method has broad popularization and application prospects.
Description
Technical field
The invention belongs to the seed storage field, relate to a kind of storage practice of Recalcitrant Seeds, specifically is a kind of seeds of rubber tree storage practice.
Background technology
Seeds of rubber tree belongs to Recalcitrant Seeds, and no resting stage, storage tolerance is not sprouted after maturation comes off immediately, dehydration, low temperature is had the susceptibility of height.When the seeds of rubber tree water content was equal to or less than 13%, seed can't germinate, and seeds of rubber tree is under the stuffiness condition, and moisture content too much goes rotten easily, and vitality generally is no more than 6 days under the condition of exposing to the sun and rain in the open air.Because seeds of rubber tree is mainly ripe in the fall, no seeds of rubber tree supply in nearly 7 months time was arranged in 1 year, sowing immediately after general collection the in the production, just the growth of seedlings of sprouting often is subjected to winter low temperature harm, cause seedling percent lower, in order to evade winter low temperature to the influence of seedling, also have employing in green house, to carry out the mode of seeding and seedling raising, but management cost, production cost are bigger, are difficult to large-scale application on producing.
At present, for avoiding winter low temperature to the influence of growth of seedlings, generally the seed of collecting is carried out the short-term storage, sowed again 1 year summer, thereby can make the seedling of firm sprouting avoid the winter low temperature phase, improve seedling percent.Seeds of rubber tree should keep seed moisture content in storage, certain oxygen content and suitable temperature are provided again, keeps the vitality of seed.In addition, a kind of new type rubber of having applied in production is set the bud grafting seedling method---and bamboo grows budding seedling growing process needs the whole year provides seed, in order to realize the bamboo grows factorial seedling growth.Yet, still do not have a kind of more stable a large amount of seeds of rubber tree storage practices to utilize for producing to go up at present.
Summary of the invention
The objective of the invention is provides a kind of seeds of rubber tree storage practice at the deficiencies in the prior art, solved the not long keeping problem of seeds of rubber tree, realized seeds of rubber tree storage a middle or short term, reach the purpose that seeds of rubber tree is provided the whole year, for the batch production production of bamboo grows budding seedling growing process provides technical guarantee.
The technical solution adopted in the present invention:
A kind of seeds of rubber tree storage practice, its concrete steps are as follows:
1, seed selection: will produce a large amount of seeds of rubber tree of collecting and estimate and roughly select that removal has been germinateed or mildew and rot seed; Choose water content and be used for storage at the normal seed more than 20%.
2, sterilization: the carbendazim solution seed soaking sterilization with 1～3% 4～6 hours, take out seeds of rubber tree then and dry.
3, storage: dry after getting thin river sand and spraying the sterilization of 0.5～1% carbendazim solution; At the thick thin river sand of storage frame bottom shop one deck 2～3cm, at 2～3 layers of seeds of rubber tree in thin river sand upper berth, keep seed from frame 2～3cm; By weight for seeds of rubber tree: the ratio of composite dose=40～60:1 of seed storage is got composite dose of seed storage, allows be spread on the seed after its suction 140～160%; Then, above composite dose of seed storage, repave 2～3 layers of seeds of rubber tree, composite dose of the son storage of sowing seeds as stated above; Adopt same procedure to repave composite dose of 2 layers of seeds of rubber tree and seed storage, at last, on composite dose of top layer seed storage, spread the thick thin river sand of 5～10cm, to preserve frame then places storeroom to preserve, the control of the temperature of storeroom is at 20～27 ℃ during seed storage, and relative moisture remains on 40～60%.Composite dose of described seed storage is with active carbon and water-loss reducer mixing and make, wherein by weight: active carbon: water-loss reducer=1:1～5.
Described water-loss reducer is acrylamide and acrylic acid salt crosslinking copolymerization thing or starch grafted acrylate crosslinking copolymerization thing.
Seeds of rubber tree storage practice provided by the invention is simple, by seed selection, sterilization and storage, the processes such as temp. and humidity of control storeroom, solved seeds of rubber tree storage in bulk a middle or short term problem, realized the annual purpose that seeds of rubber tree is provided, for the batch production production of bamboo grows budding seedling growing process provides technical guarantee, has broad prospect for its application.
