Abstract
The invention discloses a seed introduction method of submerged plant vallisneria, which comprises the steps of collecting ripening fruits of the vallisneria, removing epicarp, obtaining seeds, washing the seeds with clean water within 0-24h to keep the seeds moist, transporting the collected seeds to a destination by a water-culture method, mixing the seeds transported to the destination with moist river sand, refrigerating the seeds at 0-10 DEG C, preserving the seeds by shading above 95% till complete darkness, ventilating and replenishing water frequently, maintaining a moisture content of each seed to be 35-50%, sowing the preserved seeds in a mixed matrix, a soil matrix or a yellow clay matrix, controlling a temperature to be 10-30 DEG C, the illumination intensity to be 800-3500LUX, and the everyday illumination time to be 10-12h, allowing the seeds to germinate and grow, obtaining germinated seedlings, planting the germinated seedlings in the mixed matrix with a 10-15cm water level for culturing, managing other conditions according to a convention, planting the vallisneria, and allowing the vallisneria to grow. The mixed matrix comprises the following components by total mass fraction: 20-40% of sand and 60-80% of soil. The seed introduction method is long in seed preservation time, high in germination rate, and high in emergence rate and planting survival rate.
Description
Technical field:
The invention belongs to the plant propagation technical field, be specifically related to the introduction method of a kind of submerged plant eel grass.
Background technology:
Eel grass (Vallisneria natans (Lour.) Hara) belongs to Vallisneria plant (Vallisneria L.), and Hydrocharctaceae draft submerged plant, have another name called flat grass, noodles grass etc., and what leaf was linear, green, thin and transparent, long reaches 2 meters; Its plant acaulescence, grow thickly, emerald green, because containing more nutrition, becoming and raise the good feed of freshwater fish, and there is very high economic worth; Its strong adaptability, have a very wide distribution, be distributed widely in the Different Waters ecosystem of the torrid zone, the world, subtropics and Temperate Region in China, distribution is in various degree also arranged in the water body of China's Mainland; It has the advantages such as tolerance is strong, light compensation point is low, fertility is strong, is one of the most common, most important sociales of submerged vegetation in Chinese Inland Water.
Yet, due to China's economy and social development, water body is polluted to some extent in recent years, function of water body is degenerated and is caused aquatic vegetation to disappear.Eel grass is as the sociales of submerged vegetation, its quantity reducing rapidly, area sharply dwindling, superiority is in continuous reduction, even at a lot of local these species, disappear.The problem of water environment has caused concern and the attention of the whole society, and one of important and key link of water environment regulation and recovery is exactly to recover aquatic vegetation.Eel grass often is used as exploiting species and the constructive species of aquatic vegetation ecological recovery and reconstruction, so the problem of introducing a fine variety of research eel grass not only has important theory significance, and is of great immediate significance.
Introducing a fine variety of eel grass generally has plant to introduce a fine variety, hibernaculum is introduced a fine variety introduces a fine variety three kinds of planting methods with seed.Because seed is little, quantity is many, be convenient to gather, easy to carry, so seed is introduced a fine variety, be the most frequently used, most convenient, the most effective planting method.But, the problems such as seed is introduced a fine variety common existence transportation difficulty, short, not anti-deposit of holding time, germination rate is low, emergence rate is not high, planting survival rates is low, therefore, solve the eel grass seed transportation, preservation, germinate, emerge and the field planting problem is that eel grass is introduced a fine variety the guardian technique that must solve.
Summary of the invention:
The purpose of this invention is to provide that a kind of seed holding time is long, germination rate is high, seed sprouting is neat, the introduction method of the submerged plant eel grass that emergence rate and planting survival rates are high.
The introduction method of submerged plant eel grass of the present invention, is characterized in that, comprises the following steps:
(a) gather: gather the ripening fruits of eel grass, remove exocarp and obtain seed, clean with clear water in 0～24 hour, to keep seed moistening;
(b) transportation: the seed of collection is transported to destination by the water planting mode;
(c) preserve: the seed that will be transported to destination, with after moistening river sand mixes, refrigerates under 0～10 ℃ of environmental condition, and shading is preserved more than 95% to complete darkness, and often breathes freely and keep the skin wet, and the water content that maintains seed of take is 35～50%;
(d) sprout: by the planting seed kept, in mixed-matrix, earth or yellow clay matrix, controlling temperature is 10～30 ℃, and intensity of illumination is 800～3500LUX, and every day, light application time was 10～12h, and seed is just sprouted and growth, obtains the seedling sprouted;
(e) field planting: the plantation of the seedling of sprouting is cultivated in the mixed-matrix that 10～15cm water level is arranged, and other is managed routinely, eel grass field planting growth;
Described mixed-matrix, by gross mass mark 100%, is comprised of sand 20～40% and soil 60～80%.
The temperature of described step (d) is preferably 20～25 ℃, the sprouting of applicable seed and the growth of seedling of this temperature.
The intensity of illumination of described step (d) is preferably 1500～3000LUX, the sprouting of applicable seed and the growth of seedling of this intensity of illumination.
The solution that the present invention is favourable eel grass introduce a fine variety at seed the transportation difficulty, short, the not anti-deposit of holding time that exist in process, the problem such as germination rate is low, emergence rate is not high, planting survival rates is low, utilize the introduction method of submerged plant eel grass of the present invention, can extend significantly the holding time of eel grass seed, its holding time can reach 90～180 days, promote the sprouting of eel grass seed, germination rate can arrive more than 90%, and seed sprouting is neat, emergence rate can reach 75～85%, and planting survival rates can reach more than 80%.Therefore use introduction method of the present invention to obtain good effect, overcome the eel grass seed and introduced a fine variety not anti-storage in process, emergence rate and the low phenomenon of planting survival rates; The method is simple to operate, draws materials conveniently, with low cost, is applicable to long distance, round-the-clock introducing a fine variety; The method provides technical support for the utilization of eel grass Industrialization of seeds and seedlings, for aquatic vegetation ecological recovery and reconstruction provide technical guarantee.
