Method to produce stevia seedlings and individual vegetation container for its realisation

FIELD: agriculture.

SUBSTANCE: group of inventions concerns crop sector. The method including preparation of green cuttings. At the same time a freshly cut green cutting is taken with two pairs of leaves and is placed into an individual vegetation container with a soil substrate and the possibility to create conditions of a "moist chamber" by means of insulation of a separate each green cutting. Moisture of the soil substrate makes 75-80%, the average air temperature - 20-23°C, the relative moisture of air 65-70%, and timing of seedlings production makes 24-25 days. Seedlings are planted together with the lower reservoir of the vegetation container. The container comprises a lower reservoir in the form of a sleeve, an upper reservoir in the form of a sleeve, which is arranged as capable of entering into the first reservoir up to the simultaneous contact, forming a line of contact of the second reservoir with the surface of the soil substrate and the inner surface of the first reservoir. At the same time the contact increases as diametres of the first and second reservoirs match at the level of 4/5 of the first reservoir height. The bottom of the first reservoir is equipped with holes. A rooted green cutting is planed into the soil substrate. The lower reservoir of the container is made of a dissolving material of vegetable origin, which is decomposed in soil by soil microorganisms. At the same time the diametre of the lower reservoir bottom is selected as 1.5 times more than the maximum size of the root system of the green cutting when planted.

The technical FIELD TO WHICH the INVENTION RELATES.

The invention relates to agriculture, in particular for rooting of green cuttings and transplanting of stevia (Stevia rebaudiana (Bertoni) Hemsley) without the use of growth stimulants heterogeneous nature by creating optimal microscopy (constant humidity effect "wet chamber") for rooting of green cuttings, and can be used both in the greenhouse and outside protected ground.

The LEVEL of TECHNOLOGY

A method of obtaining seedlings stevia green cuttings rooted in seed boxes (see Dzyuba OO abstract. Kida. Biol. of Sciences, St. Petersburg, 1999; Dubansky M.M. abstract. Kida. C. agricultural Sciences, Ramon, 1999).

The disadvantage of this method is the low survival rate of green cuttings.

A method of obtaining rooted cuttings of stevia (Stevia rebaudiana (Bertoni) Hemsley), including the treatment of cuttings with an aqueous solution indolylmethane acid with a concentration of 50 mg/l by immersion in a solution followed by rooting in the wet substrate containing sand at high humidity, the cuttings for rooting use 2-3 day shoots, which 2/3 cut leaf blades, the processing solution indolylmethane acid at a concentration of 50 mg/l of conduct for 20-26 hours, and as the substrate of the IC is result washed river sand (see Pat. Of the Russian Federation No. 2079267, CL 01G 1/00, publ. 20.05.97).

The disadvantage of this method is the pre-processing of green cuttings water and growth stimulants, lack of isolation of the plants in case of photointensity.

A method of obtaining seedlings stevia green cuttings rooted in seed boxes and paper cassettes (see Zubenko V.F., Kovalchuk M.I., GRES E.I. Sugar beet, 1992. No. 6. - Ñ.38-39).

The disadvantage of this method is the pre-processing of green cuttings water and growth stimulants, additional operations on the powder planting material, lack of isolation of the plants in case of photointensity, unregulated water evaporation leaf surface, disturbance of the root system of the seedlings when removing seedlings from the boxes before planting.

The closest in technical essence and sufficient positive effect and adopted by the authors for the prototype is a method of obtaining seedlings of stevia, including the preparation of green cuttings, and the green stalk fresh take with two pairs of leaves and placed in individual growing container with soil substrate with the possibility of creating conditions "wet chamber" by isolating each green handle, and the humidity of the soil substrate is 75-80%, average the air temperature 20-23°C, the relative humidity of 65-70%, and the deadline for receipt of seedlings for 24-25 days. (RF patent for the invention №2289908, CL A01G 1/00, A01G 9/02, publ. 27.12.2006,).

Known individual vegetation container containing the first (lower) capacity in the form of glass, the second (upper) capacity in the form of glass, which is made with the possibility of entering the first tank to the simultaneous contact, forming a line of contact between the edge of the second vessel with the surface of the soil substrate and the inner surface of the first container, the contact increases with matching diameters of the first and second containers at level 4/5 of the height of the first container, with the bottom of the first vessel with openings in soil planted establishing seed green stalk. (RF patent for the invention №2289908, CL A01G 1/00, A01G 9/02, publ. 27.12.2006,).

The disadvantages of this method and individual growing container is insufficient survival rate of seedlings, the reliability of its receipt and a significant amount of time monitoring of compliance with the required humidity of the soil substrate 75-80%, the temperatures of 20-23°C and a relative humidity of 65-70% when receiving seedlings.

The lower survival rate of seedlings due to the fact that before boarding the resulting seedlings stevia to be drawn from the container thus produced is walking violation of the roots of seedlings, that reduces its survival.

The reduction in the reliability of obtaining seedlings of stevia due to the fact that monitoring of compliance with the required humidity of the soil substrate 75-80%, the temperatures of 20-23°C and a relative humidity of 65-70%, upon receipt of seedlings in a known way and individual growing container is carried out manually, which permits the presence of subjective errors. It is possible to ignore the presence of deviations of temperature and humidity from required, which reduces the reliability of obtaining seedlings stevia.

In addition, manual control over compliance with the specified conditions and their maintenance requires considerable time. So with an average time of manual operation of one individual growing container 1 minute, the time to service 1200 containers is 20 hours.
