Description

(54) SIMBIRNT-2 PREPARATION, STIMULATING THE YIELD OF PLANTS

I

The invention relates to agriculture, in particular to the means of stimulating the growth of agricultural crops.

Known drugs that stimulate the development and growth of plants, obtained from pure cultures of fungi zndofitov isolated from the roots of wheat, oats, potatoes, wheat grass, mother, and stepmother. Each preparation consists of metabolic products of the corresponding endophyte dissolved in 70% ethyl alcohol. The treatment with one of the above seed preparations Pshenchenny, cucumbers or tubers of potatoes before sowing contributed to crop yield 1.

A disadvantage of known growth stimulators is the low activity of preparations obtained from plant endophytes with the highest medicinal value.

Known is the preparation Simbiont-1, which is made from endophytes, isolated from the roots of gin-shen. The drug is effective only under good plant growth conditions 2.

The disadvantage of the known preparation is the lack of raw materials, i.e., ginseng roots, necessary for obtaining the culture of endophytes, which excludes mass production of the preparation.

The purpose of the invention is the expansion of the raw material base for the production of stimulators and assortments. incentive funds.

The goal is achieved by the fact that as the raw material for its production, use of the sindophytes, isolated 1e from easily accessible sea buckthorn roots.

The manufacture of the proposed preparation from sea buckthorn endophytes provides cheaper feedstock and an expansion of the production of the stimulator. In addition, with improved production, difficulties in renewing the culture of the fungus or its restoration in case of loss are eliminated.

In practical use, 1 ml of the claimed preparation is dissolved in 10 liters of water. AT

I obtained the solution soaked the seeds oiyptsov 30 min at 35 C before proceeding: 11. Tubers of potatoes are sprayed with a solution of the drug of the same concentration before planting. 3 According to the stimulating activity of the proposed drug is not inferior to the known. Applying the invention to cucumbers under conditions of ground soil provides a yield increase from IS d 27.1%. Example. The drug was tested for two seasons on cucumbers during the night of the experiments at the greenhouse state farm Marfino (Moscow) in the hangar greenhouses in winter. In tab. 1 shows the results of the influence of the well-known Symbiont-G and the proposed preparations, obtained when working with the grade TLCA-211 in the experience of 1978-1979. at 30 harvest. In opgge 1979-1980 The preparation was used on the Magat variety in the winter turnover (40 crop turns). At the same time, under the conditions of model experiments, the effect of the drug on the absorption of oxygen by the soil dispersal system (greenhouse soil with the roots of seven-day cucumber seedlings) and the branching of the roots was studied. Since the preparation is made on an alcohol basis, a variant was introduced in which the seeds were treated with 75% ethyl alcohol.

 The absorption of Oj by the soil without roots amounted to 3.57 ml / kg of dry soil per hour.

The results of the effect of the proposed drug on the absorption of oxygen by the soil with roots, the branching of the roots and the yield of cucumbers are given in Table. 2. From the table it can be seen that the effect of the drug is manifested in an increase in the rate of absorbed oxygen and the increased betting of the roots already at the age of seven days. The yield increase is 15%. The effect of the alcohol was unreliable, since the active principle is the metabolites of the endohyte fungus dissolved in Strth, and not the alcohol itself. In addition, production testing of the claimed drug was conducted on potatoes (Lorch variety) in 1979, and the Druzhba state farm in the Pereslavsky district of the Yaroslavl region. On the control varante, the yield was equal to 18 t / ha, and on the variant treated with the preparation, 23 t / ha. The yield increase was 28%, and the economic effect on 35 hectares - 35 thousand rubles. It was noted the absence of phytophtora. Table 1
