The method of growing seedlings of cabbage in hydroponics

 

(57) Abstract:

Usage: agriculture, specifically for growing plants in hydroponic greenhouses. The essence of the invention: a method of growing seedlings of cabbage in hydroponics includes planting, caring for plants, pick, his conduct multilevel narrowshelving hydroponic plants with cells placed in tiers. After exercise in the cells of the upper tier and then at regular intervals of time move cells of the upper tier and each of the tiers from top to bottom, except the closest to the base, and carry out pick seedlings from cells in the layer closest to the base. 1 Il.

The invention relates to agriculture, specifically, to a method of growing seedlings of cabbage in the greenhouse for hydroponics.

A known method of growing seedlings of cabbage in hydroponic greenhouses, which consists in sowing seeds sown in boxes or cassettes, placing them on the shelves hydroponic greenhouses, plant care, including dosvechivanie, pick seedlings in nutrient pots (A. A. Autka "Seedlings of vegetable crops". Minsk "Uraji" 1992, S. 68 87).

As a hydroponic setup used racks with fixed, desimasala will be uneven as the degree of illumination, which degrades the quality of seedlings and reduces the yield of cabbage.

The task was to develop a method of growing seedlings of cabbage narrowshelving tiered method of hydroponics, ensuring a higher quality product yield of cabbage by improving the uniformity of illumination and planting density of seedlings per unit area.

This problem was solved by the present invention. In the method of growing seedlings of cabbage in hydroponics, including planting, caring for plants, pick, according to the invention, the method is carried out on a multi-narrowshelving hydroponic plants with cells placed in tiers, with the sowing produced in cells of the upper tier, and periodically, through even time intervals to move the cells in each of the tiers except the closest to the base to produce pick seedlings located in the cell layer closest to the base.

Periodic permutation of cells with seedlings during the entire cycle of growth with top-tier installation with more vysokointensivnogo irradiation on the lower tier with less illumination increases the uniformity produced by all plants total dose oblucheniyakh will increase the sowing density per unit landing square in Teplice, which will increase its productivity.

The method is illustrated in the drawing, which schematically shows a cross-section hydroponic systems for growing seedlings of cabbage.

Narrowshelving stacked hydroponic installation 1 with the frame of the inclined beams 2 equip germinators in cells 3, placed in the holes 4 cassettes 5 tiers. In cells 3 sow seeds of plants 6.

Seedlings 6 is irradiated by a source of optical radiation 7, placed on the outer side hydroponic plants 1, and irradiation sources 8 installed inside of the frames of the units 1. Irradiation sources 7 and 8 are equipped with reflectors 9.

The method is as follows. First sowing produced in cell 3, installed in the cassette 5 of the upper tier hydroponic plant 1 and at equal intervals of time move the cells in each of the tiers except the closest to the base, and produce pick seedlings located in the cells closest to the base. Cultivation of seedlings of cabbage is carried out in a temperature and humidity, light and gas mode, in which the parameters of irradiation and temperature decrease from top to bottom hydroponic setup with which to Finance hydroponic setup 1.1 to 1.2 and 1.2 1.3 times.

An example of performing the method. Cultivated seedlings early cauliflower - fast buck, Snowflakes, Leningrad, 126, Early Gribovsky 1355.

Seeding was carried out in cells, which are then installed in the cassette at the beginning of the upper tier six-level narrowshelving hydroponic setup in the form of "prism" with the frame of the inclined beams. At equal intervals of time 3 4 days the cells of all layers except the bottom, closest to the base, moved to a place nearby closer to the base installation. In the process of vegetation comply with the following modes: in the lower tier installation provided 16 18oC during the day and 8 to 10oC at night, the top tier, respectively, 17 - 19oC and 9 of the 11oC. the irradiation Intensity in the lower tier of the day was provided by 15 of 17 W/m2HEADLIGHTS, and the upper floor 18 20 W/m2the relative humidity of the air below was 45 to 55% of the top 40 to 50% and the concentration of carbon dioxide, respectively, of 0.07% and 0.06%

Providing the specified modes of cultivation has greatly improved the quality of seedlings of cabbage and duration of the cultivation 95 100 days to increase the yield of cabbage compared to control landing on shelves in 2 to 3 times.

Thus, the proposed the b cultivation of cabbage seedlings in hydroponics, including planting, caring for plants, pick, characterized in that the method is carried out on a multi-narrowshelving plants with cells placed in tiers, with the sowing produced in cells of the upper tier and periodically, at regular intervals of time to move the cells in each of the tiers except the closest to the base, and produce pick seedlings from cells in the layer closest to the base.
