step (3) adding a gel culture medium 3 solution into each planting hole 201, so that the height of the gel culture medium 3 solution in each planting hole 201 is 1/3 of the height of each planting hole 201;
step (4) reducing the temperature of the gel culture medium 3 solution at the bottom of the planting hole to be solidified, and sowing a plurality of plant seeds with the number of 3000 seeds/m into each planting hole 2012Furthermore, at this time, the sowing tray 1 can be divided into a plurality of areas by the partition plates 104, and different plant seeds can be sown in different areas;
after each planting hole 201 is planted, continuing to add the gel cultivation medium solution into the sowing plate 1 until the liquid level height of the gel cultivation medium solution in the sowing plate 1 is 0.2cm higher than the plane of the upper surface of the planting hole 201, sterilizing and disinfecting the seeds by using the temperature of the gel cultivation medium solution, and fixing the positions of the seeds by using the solidification characteristic of the gel cultivation medium solution; the gel culture medium 3 solution is higher than the height of the planting holes, which is beneficial to forming an integral structure of the solidified gel culture medium 3 and avoiding falling off due to the drawing-off of the bottom movable bottom plate 103.
Step (6), the temperature of the gel culture medium 3 solution at the bottom of the planting hole is reduced to be solidified, the movable bottom plate 103 is taken out from the bottom of the seeding tray and is placed on the placing platforms of the side plates 101 to be used as a sealing plate, the seeding bottom plate 102 is shielded, the effects of light shielding and moisture preservation are achieved, and the germination of seeds can be promoted;
and (7) taking off the movable bottom plate 103 after the plant seeds germinate, and planting after the root system grows to a proper length. The gel culture medium of the method is thin, is beneficial to culturing small varieties of seeds, is beneficial to seed respiration, and promotes the rapid growth of plants.
Compared with the situation that the plant seeds are sown after the gel culture medium 3 solution is added to the plant through holes 201, a part of the gel culture medium 3 solution is added into the plant holes 201, the plant seeds are sown after the gel culture medium 3 solution is solidified, and the gel culture medium 3 solution is continuously added after the sowing is finished, so that the plant seeds can be sterilized by using the temperature of the gel culture medium solution on the premise of ensuring uniform distribution of the plant seeds.
In this embodiment, in the step (2), the mass ratio of the gel medium to the water may be further 0.5: 200.
example 8: same procedure as in example 7, but with a ratio of gel medium to water mass of 5:200, heating for 2 hours, wherein the ratio of the height of the added gel culture medium 3 solution to the height of the planting holes 201 is 3: 4, the number of the plant seeds is 50000 grains/m2The height of the liquid level of the gel culture medium 3 solution in the sowing tray 1 is 1cm higher than the plane of the upper surface of the planting hole 201. In this embodiment, in the step (2), the mass ratio of the gel medium to the water may be further 10: 200.
in this embodiment, in the step (3), the ratio of the height of the solution of the gel culture medium 3 added first to the height of the planting holes 201 may be 1. The main difference between this example and example 7 is that the ratio of the height of the gel culture medium 3 solution added first to the height of the planting holes 201, the larger the amount of the gel culture medium 3 solution added first to the planting holes 201, the larger the volume of the plant seeds, the larger the plant seeds have more developed root systems than the smaller seeds, and the large seeds need to provide sufficient growth space for their root systems during germination; the liquid level height of the gel cultivation medium 3 solution in the corresponding sowing tray 1 is higher, the gel cultivation medium positioned above the planting hole 201 after solidification ensures that the gel cultivation medium in the planting hole 201 cannot be separated, the higher liquid level height of the gel cultivation medium 3 solution can provide better supporting force for the whole gel cultivation medium 3 solution solidification, and economic loss caused by separation is reduced.
The method is suitable for cultivating the variety with larger seeds and developed root systems, is beneficial to the growth of the root systems, is also beneficial to improving the firmness of the gel cultivation medium and the seeds, avoids the seeds from falling off, can ensure the stability of cultivation, and is beneficial to the final quick and convenient harvesting. The plant seeds can be sterilized by cooling the gel culture medium to 45-65 ℃, and the plant seeds are not inactivated due to overhigh temperature; the gel culture medium is preferably agar, and the cooling temperature is preferably 45-55 deg.C, preferably 45 deg.C, 50 deg.C or 55 deg.C; the temperature of the thermostatic water bath is preferably in the range of 45-55 ℃, preferably 45 ℃, 50 ℃ or 55 ℃.
The ratio of the total weight of the plant seeds to the weight of the gel culture medium solution is 1: 1000-200: the sowing density is the most reasonable when the sowing density is 1000, when the plant seeds are larger, the weight of a single plant seed is large, the addition amount in the gel cultivation medium solution is relatively small, and larger gaps can be formed among the plant seeds during sowing.
The mass ratio of the gel medium to the water is 0.5: when the ratio of the gel to the culture medium is within the range of 200-10:200, the hardness of the formed gel culture medium is moderate, the medium is favorably solidified and formed, and simultaneously, the environment of plant planting and root pricking is met. The mass ratio of the gel medium to water is preferably in the range of 1: 200-5: 200.
The ratio of the height of the gel cultivation medium solution added firstly to the height of the planting holes 201 is in direct proportion to the size of the plant seeds, the larger the plant seeds are, the higher the height of the gel cultivation medium solution added firstly to the planting holes 201 is, and when the height of the gel cultivation medium 3 solution in the planting holes 201 is between 1/3-1 of the height of the planting holes 201, the height of the gel cultivation medium 3 solution added firstly to the planting holes 201 and the number of the plant seeds in each planting hole 201 can be controlled according to the size of the plant seeds, so that the characteristics of small seeds, small number and large number are ensured, too many plant seeds are prevented from being gathered in one planting hole 201, the germination process of the plant seeds is influenced, and the economic benefit is better.
