INVENTION
Patent of the Russian Federation RU2077188
METHOD OF GROWING CABBAGE DISPATCH ON HYDROPONIC
The name of the inventor: Sharupich V.P.
The name of the patent holder: Small enterprise "Patent" of the State Research and Design Institute "Giproniselprom"
Address for correspondence:
Date of commencement of the patent: 1993.08.10
Use: farming, in particular in sheltered soil. SUMMARY OF THE INVENTION: When growing cabbage seedlings, 18-22 day old seedlings are dumped in pots placed on the upper tier of a multi-level narrow-columned hydroponic plant and periodically move pots from the bottom down at regular intervals, and the ready-made seedlings are removed from the lower tier.
DESCRIPTION OF THE INVENTION
(EN) The invention relates to agriculture, in particular, to methods for growing sprouts of cabbage in greenhouses on hydroponics.
A method is known for growing cabbage seedlings in hydroponic greenhouses, consisting in seeding seedlings, cultivating seedlings under artificial irradiation and plant care (AAAutko, "Vegetable Crops", Minsk, Urajai, 1992, pp. 68-87).
As a hydroponic installation racks with fixed, non-removable plants are used. When using such an installation, the irradiation of seedlings located on different racks of plants will be uneven in the degree of irradiation, which worsens the quality of seedlings and reduces the yield of cabbage.
The task was to develop a method for growing seedlings by the method of multi-level narrow-racked hydroponics, which ensures the improvement of the quality of seedlings and the yield of cabbage due to the uniformity of irradiation and the increase in the density of planting seedlings per unit of planting area.
This object is achieved by the present invention. In the method for growing cabbage seedlings on hydroponics involving seedling seedlings, cultivating seedlings under artificial irradiation and plant care, the seedlings at the age of 18-22 days are used according to the invention, and the method is carried out on multi-tiered narrow-columned hydroponic plants with pots with plants placed in tiers at the same time Picking seedlings produce in pots of the upper tier, and periodically, at regular intervals move the pots of each of the tiers, except the near to the base and remove the seedlings from pots located on a tier near the base.
Periodic rearrangement of pots with seedlings during the whole cycle of its growth from the upper tier of the hydroponic plant with a higher intensity of irradiation to the lower tiers with less illumination leads to an increase in the uniformity of the total radiation dose received by all plants.
Growing cabbage seedlings on a multi-level narrow-columned hydroponic plant will significantly increase the density of planting per unit of planting area in the greenhouse, which will increase its productivity.

The method is explained in the drawing, which schematically shows a cross-section of the hydroponic plant for growing cabbage seedlings. The multi-tiered narrow-shelled hydroponic plant 1 contains a skeleton of inclined crossbars 2 and is equipped with vegetation in the form of trays 3 with lids 4, in the holes of which there are pots 5 with seedlings 6. Seedlings 6 are irradiated with light sources 7 located on the outside of hydroponic units 1 and irradiation sources 8 , Installed inside the frames of units 1. The irradiation lamps 7 and 8 are equipped with light reflectors 9. The method is carried out as follows. Cabbage seedlings at the age of 18-22 days are used for cultivation, they are dived into the pots 5 of the upper tier of the multi-tiered narrow-shelled hydroponic plant 1 and periodically, at regular intervals, the pots with the seedlings 6 of each of the tiers, except the one nearest to the base, are moved, and then the seedlings On the tier nearest to the base. Cultivation of cabbage seedlings is carried out in a temperature-humidity, light and gas regime, at which the temperature and irradiation parameters decrease from the top to the base of the installation, respectively, in 1.1 1.2 and 1.5 2.0 times, and the parameters of humidity and concentration of carbon dioxide Increase from the top to the bottom of the hydroponic installation, respectively, in 1,1 1,2 and 1,2 1,3 times. |
An example of the execution of the method.
Cultivated seedlings of the early cauliflower Skorospole, Snezhinka, Leningradskaya 123, early Gribovskaya 1355.
Seedlings at the age of 20 days were planted in pots installed in trays on the upper tier of a six-tiered hydroponic installation, then in pots of a neighboring tier, etc. Up to the base of the installation. At regular intervals of 4 to 5 days, trays with pots of all tiers, except for the lower one, were moved to the place of the neighbors closer to the base of the installation.
In the process of cultivation, seedlings were provided with temperature-humidity, light and gas regimes: in the lower tier of the installation, 16-18 ° C during the day and 8-10 ° C at night, in the upper tier, respectively, 17-19 ° C and 9-11 ° C, The lower level of 15 17 W / m 2 phased array, and in the upper tier 18 20 W / m 2 phased, the air humidity at the bottom was 45 55% at the top 40 50% and the concentration of carbon dioxide was respectively 0.07% and 0.06% Regimes of cultivation allowed to significantly improve the quality of cabbage seedlings and with the duration of the culture turnover 95 100 days to increase the yield in comparison with the control planting according to the prototype in 2 3 tiers.
Thus, the proposed method makes it possible to improve the quality of seedlings and the yield of seedlings and the yield of cabbage 2 3 times.
CLAIM
1 Method for growing cabbage seedlings on hydroponics, including seeding of seedlings, cultivation of seedlings under artificial irradiation and plant care, characterized in that seedlings are used at the age of 18-22 days, and the method is carried out on multi-tiered narrow-columned hydroponic plants with pots with plants placed in tiers, While the picking of the seedlings is carried out in pots of the upper tier and periodically, at regular intervals, the pots of each of the tiers are moved, except the nearer to the base, and they are removed from the pots located on the tier near the base.
