Abstract

The invention discloses a kind of non-soil culture methods, comprise the following steps:Sowing:Nursery sponge is put in seedlings nursing plate, has cross bore face-up, seed is kept flat in cross bore, 14 seeds are broadcast in each cross sponge;Seed soaking:It after broadcasting kind, is covered with waffle slab, gently pushed down, when making seedling-raising box standing 8 16 small;It uncaps:When the sprouting of more than 70% seed, abundant irradiation of uncapping, while nutrient solution is added into seedling-raising box, the water level in seedling-raising box is kept to submerge at 1/3 sponge;Field planting:Field planting basket is packed into after nursery sponge is separated, is positioned in field planting hole, the root system of seedling stretches out field planting basket at this time, in order to which it is absorbed into nutrient solution.Through the above way, present invention utilizes cavernous bodies the special of preferable water imbibition, the nutrient solution of bottom can be adsorbed, so that the seed inside cavernous body is infiltrated in nutrient solution, oxygen necessary to providing growth to seed, soil environment can be preferably simulated, effectively improves the germination percentage and survival rate of seed.

Description

A kind of non-soil culture method
Technical field
The present invention relates to a kind of non-soil culture methods.
Background technology
Non-soil culture is not have to soil, and makees matrix with the solid material of non-soil, pours nutrient solution or without any base Matter, and nursery is carried out using the mode that water planting or mist are trained, it is known as non-soil culture.By whether using matrix, and matrix can be divided into and educated Seedling and nutrient solution nursery, the former is to utilize the matrix such as vermiculite, perlite, rock wool and nutrient solution seedling;The latter does not have to any base Matter only utilizes some supporters and nutrient solution.
Soilless culture is with the matrix of non-soil, supply nutrient solution or the cultivation technique that nutrient solution is fully utilized, it is desirable that most Good rhizospheric environment.The seedling cultivated using non-soil culture mode, after field planting, because root system development is good, rhizospheric environment and without soil plant Training is adapted, and is not hindered root after field planting, is easily survived, typically no seedling-slowing stage.Meanwhile non-soil culture can also avoid soil nursery from bringing Soil-borne disease and nematode evil.Therefore, soilless culture is had to using non-soil culture.
The existing method that nursery is carried out using nutrient solution although this kind of method can improve the germination percentage of seed, is reduced The generation of pest and disease damage, but the applied amount of nutrient solution is difficult to control, and the survival rate of transplanting need to be improved, however it remains technical By force, operating difficulties, the problem of environmental sensibility is high, it is difficult to realize industrialized production.
The content of the invention
The invention mainly solves the technical problem of providing a kind of non-soil culture methods, can use simple raising seed Germination percentage and transplanting survival rate.
In order to solve the above technical problems, one aspect of the present invention is:A kind of non-soil culture method is provided, is wrapped Include following steps:
1)Sowing:Nursery sponge is put in seedlings nursing plate, has cross bore face-up, seed is kept flat in cross bore, Mei Geshi 1-4 seeds are broadcast in word sponge, nursery sponge surface can indistinctly see seed, be suitable depth;
2)Seed soaking:After broadcasting kind, covered with waffle slab, gently pushed down, into seedlings nursing plate plus water gently squeezes nursery sponge simultaneously, Sponge is made to be impregnated with water, adds water to and does not cross nursery sponge, waffle slab is taken out, when making seedling-raising box standing 8-16 small;
3)Draining:After when standing 8-16 is small, draining basket is taken out, all around four direction draining, until being not much water droplet Downwards during drop;
4)Sight is looked into:It uncaps and checks 2-3 times daily, finger gently presses down on sponge surface, and finger can feel have water just not have to spray Water, if slightly aobvious water shortage, uniformly sprays water to sponge surface, until sponge surface is sufficiently humidified so as to;
5)It uncaps:When the sprouting of more than 70% seed, abundant irradiation of uncapping, while nutrient solution is added into seedling-raising box, keep seedling-raising box In water level submerge 1/3 sponge at;
6)Thinning:When seedling is in two panels cotyledon period, thinning is carried out at this time, if there is the seedling of two or more in same cross bore When, the most healthy and the strongest one can be left, remaining cuts off;
7)Field planting:One leaf of seedling wholeheartedly when, by nursery sponge separate after be packed into field planting basket, be positioned in field planting hole, at this time seedling Root system stretch out field planting basket, in order to which it is absorbed into nutrient solution.
In a preferred embodiment of the present invention, seed include pellet seed and common seed, pellet seed at seeding time, 1-2, depth 3-5mm are broadcast in each cross bore, common seed at seeding time, broadcasts 2-4, depth 2- in each cross bore 3mm。
In a preferred embodiment of the present invention, after uncapping 2-3 days it is every also in compared with short status, still needing to due to seedlings root Its observation 2-3 times when finding sponge surface water shortage, is sprayed water in time;About after planting 5-6 days, when having can be seen that 50% under draining basket Stop water spray when root system is grown.
In a preferred embodiment of the present invention, after uncapping, the pure nutrient solution of the 500ml-900ml added into seedling-raising box Or the mixing liquid of water and nutrient solution.
In a preferred embodiment of the present invention, 2-3 days after Seeding planting, need respectively to spray water once in the morning, afternoon and evening daily, with profit Slow seedling;After seedling slow seedling survives, when boiler alarm sounds, in time to its Additional nutrient solution, without being carried out again to it Others operation.
The beneficial effects of the invention are as follows:Present invention utilizes cavernous bodies the special of preferable water imbibition, can be by bottom Nutrient solution absorption come up so that the seed inside cavernous body is infiltrated in nutrient solution, and cavernous body have preferable gas permeability, Oxygen necessary to providing growth to seed, can preferably simulate soil environment, effectively improve germination percentage and the survival of seed Rate.
