The method of growing plants of cucumber

 

(57) Abstract:

The invention relates to a plant cultivation under artificial lighting. During the first 18 to 22 days after transplanting cucumbers produce radiation with an intensity equal to 25 - 30% of maximum. The following 14 - 16 days characterized by a maximum intensity values. The last 28 - 32 days irradiation intensity is gradually decreased to 28 - 30% of maximum. This allows to reduce energy consumption and increase the yield of 3 - 4 times. 2 C.p. f-crystals.

The invention relates to agriculture, in particular the production of vegetables in greenhouses, greenhouses, hydroponic technology.

There is a method of growing plants of cucumber, including the irradiation of plants in artificial light.

The disadvantage of this method is the higher energy consumption per unit of production and low productivity.

The task was to create a method of growing plants of cucumber with low energy consumption, high productivity.

The claimed invention solved the problem of reducing energy consumption, improving performance.

In the pic is for the first 18-22 days after planting of seedlings produced in the irradiation intensity, equal to 25-30% of the maximum, subsequent 14-16 days with maximum intensity, and in the last 28-32 days gradually diminish to 28-30% of maximum.

In a preferred embodiment of the method over the last 26-32 days irradiation intensity is reduced by 10-12% every 5 days.

Preferably, the cultivation is carried out for 68-70 days at a planting density of 10-12 plants/m2and plant height of 1.0-1.2 m, and the radiation produces light sources with power density of 0.9-1.2 kW/m2at maximum irradiation intensity of 150 W/m2in the field photoactive radiation.

The claimed invention achieves the following technical result.

The selection process of growing cucumber with rational mode of irradiation with low intensity irradiation during the first 18 to 22 days after planting of seedlings and in the last 28-32 days will significantly reduce the power consumption for irradiation of plants.

The reduction of the power density exposure to 0.9-1.2 kW/m2and maximum oblojennosti up to 150 W/m2in the field photoactive radiation will reduce installation power exposed the cages and the optimum irradiation can improve productivity by 3-4 times.

The method of growing plants of cucumber illustrated by the example of its execution.

In the greenhouse of block type with narrowshelving stacked hydroponic plants by the present method were grown cucumber varieties of TAA "Uncle Stepa".

Pots with seedlings were placed in trays hydroponic plants. Planting density was 10 to 12 plants per 1 m2area when plant height of 1.0-1.2m power density of irradiators is 0.9-1.2 kW/m2.

During the first 20 days after planting seedlings was irradiated with an intensity equal to 25-30% of the maximum is 150 W/m2in the field photoactive radiation, i.e., 35-45 W/m2.

In the next 15 days the plants were irradiated with a maximum intensity of 150 W/m2.

In the past 28-32 days the intensity gradually decreased by 10-12% every 5 days. When semidesjatiletiem the cultivation yield was 100-120 kg/m2.

Control planting cucumber varieties of TAA "Uncle Stepa" was performed at traditional greenhouses density planting 3-5 plants per 1 m2area and plant height of 1.8-2.0 m At nine months of cultivation, the yield amounted to 25-30 kg/m2.

Thus the conversion of electricity consumption.

1. The method of growing plants of cucumber, including the irradiation of plants in artificial light, characterized in that during the first 18 to 22 days after planting of seedlings produced in the irradiation with an intensity equal to 25-30% of the maximum, subsequent 14-16 days with maximum intensity, and in the last 28-32 days gradually diminish to 28-30% of maximum.

2. The method according to p. 1, characterized in that in the past 26-32 days irradiation intensity is reduced by 10-12% every 5 days.

3. The method according to p. 1 or 2, wherein the cultivation is carried out for 68-70 days at a planting density of 10-12 plants/m2and plant height of 1.0-1.2 m, and the radiation produces light sources with power density of 0.9-1.2 kW/m2at maximum irradiation intensity of 150 W/m2in the field photoactive radiation.
