Description

The invention relates to agriculture and can be used to increase crop productivity in a protected ground.

One of the known methods of stimulating the growth of agricultural plants is their treatment with a solution of potassium hydroxide (to stimulate growth) and a solution of acetic acid (to accelerate leaf aging) (RF patent No. 2161406, A01N 37/02, A01N 59/00, publ. 10.01.2001 )

Known patent of the Russian Federation No. 2272044 from 09/13/2004, representing a growth regulator (epin-extra) and plant development with a pronounced anti-stress adaptogenic effect. The epin-extra preparation contains as an active ingredient a highly purified 24-epibrassinolide synthesized according to the original method, which indirectly through the hormonal system affects the activity and biosynthesis of oxidative cycle enzymes, enhances seed germination and plant growth, increases resistance to biotic and antibiotic factors, increases yield and improves its quality.

Closest to the claimed one is a method of presowing treatment of seeds of agricultural crops with the active substance - activated water, in which the seeds were first soaked in a solution of activated water, after which they were dried to a certain moisture content (RF patent No. 2170499, A01C 1/00, publ. 20.07 .2001).

The disadvantages of these methods are: high complexity in the manufacture and use, as well as lack of effectiveness, due to a very short period of exposure to the plant. Apparently, due to the noted shortcomings, these methods, as well as other growth regulators, did not find large-scale industrial application.

The technical task of the invention is to reduce the period of growing peas by stimulating the process of photosynthesis.

The problem is achieved in that in a method of stimulating pea growth in a protected ground for breeding purposes, comprising treating the plants with the active active substance, according to the invention, an ozone-air mixture with an ozone concentration of 0.5-3 mg / m ^{3 is} used as an active substance, and plants are treated for 10-30 minutes twice in the dark, every 3 hours, during the entire growing season.

The novelty of the claimed technical solution lies in the fact that an ozone-air mixture is used as a biologically active substance in the intended treatment modes, which allows to accelerate plant growth while eliminating environmental pollution.

It has been experimentally established that the dose of ozone below the specified minimum value does not have the desired effect. A dosage of ozone above the indicated maximum level causes a burn of plants.

Since the invention uses a commonly available environmentally friendly substance, it provides the possibility of wide industrial use in agricultural production.

An example of a specific implementation of the method of stimulating the growth of peas in protected ground for breeding purposes: the studies were carried out in the phytotron-greenhouse complex of KNIISKh in two greenhouses with the same area and the same microclimate. Pea cultivation has been carried out since December 20, 2010. The microclimate mode in greenhouses during daylight hours is as follows: air temperature t≈25 ÷ 27 ° C; humidity φ≈65%, drip irrigation, and in the dark, temperature t≈14 ÷ 16 ° C; humidity φ≈65%, drip irrigation). Pea seeds grade "LEGION" seeded in two greenhouses, postemergence, about 2 cm in height, in a greenhouse in a dark interval ⁰⁰ to 22 ⁰⁰ to 6 o'clock in the morning twice per night treated plants ozone concentration 0.5-3 mg / m ³ for 10-30 minutes every 3 hours, during the entire growing season.

Under general equal conditions, in the 2nd greenhouse, electrozonal installations were used.

The results of the study are presented in table 1. For measurements, the average growth of the 10 most typical pea plants was used.

Table 1 Results of the influence of ozone-air treatment on the growth and development of peas of the LEGION variety The number of days from the moment of sowing Average height of 10 most typical plants Control cm Experienced cm 7 2 3,5 fourteen 10 16 21 26 37 28 38 49 35 47 65 (flowering) 42 53 71 49 64 (flowering) 71

When analyzing the effect of ozone-air treatment of peas of the LEGION variety, the following was found out: in the first weeks, the height of the seedlings in the greenhouse, where the ozone-air mixture was treated, was 1.5 times higher than the height of the seedlings in the control greenhouse.

Flowering of peas in an experimental greenhouse occurred 2 weeks earlier than that of peas in normal conditions.

Thus, on the basis of the conducted studies, the effectiveness of the claimed method of stimulating the growth of peas in protected ground for breeding purposes was confirmed, which manifests itself in a reduction in the growing time of peas of the LEGION variety by 2 weeks due to the stimulation of the photosynthesis process.

Claims (1)

A method of stimulating pea growth in a protected ground for breeding purposes, comprising treating the plants with the active substance, characterized in that an ozone-air mixture with an ozone concentration of 0.5-3 mg / m ^{3 is} used as the active substance, and the plants are processed for 10 -30 min twice in the dark, every 3 hours, during the entire growing season.
