Abstract

FIELD: agriculture.

SUBSTANCE: method of growing linen flax comprises the main autumn and spring presowing treatment of soil, seed treatment, planting and treatment of crops. The crops are treated in phase "herringbone" at the plant height of 3-12 cm with the aqueous solution of the biologically active substance "Floravit ®" in an amount of 1·10-4 g/l with a flow rate of working fluid of 200-400 l/ha.

EFFECT: invention enables to improve crop yield of the culture and quality of the obtained flax product.

Description

1. The technical field

The invention relates to agriculture and is intended for crop production, namely for the effective cultivation of long flax, the main variety of flax cultivated in Russia for use as valuable plant materials for the textile and paint and varnish industries (Flax. Large Illustrated Encyclopedia. M., Ast -Astrem. 2010, p. 287). The method is carried out by autumn and spring tillage, seed dressing, pre-emergence harrowing and crop care, including the treatment of crops with a biologically active substance, when the feed additive (CD) "Floravit®" in the amount of 1 · 10 ^{-4 is} used as a biologically active stimulating substance g / l at a flow rate of 200-400 l / ha

2. The level of technology

It is known the use of the protective-stimulating composition "Ecost" for seed treatment and processing of crops. Ecost is used together with herbicides, insecticides and microelements for growing flax and other crops, including tillage, presowing treatment of seeds, etc. (Plant growing. Edited by prof. Vasilyeva P.P. M., "The Ear". 1975).

The closest analogue of the claimed proposal, adopted as its prototype, is a method of growing flax, including autumn and spring tillage, seed dressing, harrowing the soil, caring for the crops with their treatment with succinic acid at a rate of 1-10 g / ha (RU No. 2216922, class A01G 1/00, А01С 21/00, А01N 61/00, 03/19/2002).

The disadvantage of the prototype is the relatively high cost, the complexity of the preparation of solutions for processing, especially in combination with other plant protection products, with a high rate and use of succinic acid.

3. Disclosure of invention

The problem to which the invention is directed, is to increase crop yields and the quality of the resulting flax products.

The problem is achieved in that the method of growing flax flax includes spraying flax plants in the phase of the "herringbone", with a plant height of 3-12 cm, a biologically active substance, which is used as a feed additive "Floravit®" in an amount of 1 · 10 ^-4 g / l, with a flow rate of 200-400 l / ha.

4. The implementation of the method

 The method was performed as follows.

The forerunner of long flax in a nine-field crop rotation was white mustard seeds. In autumn, the main plowing was carried out by an aggregate of the MTZ 12 + 21 + UNIA 2 + 1 type (a small reversible plow). In the spring, harrowing - closing moisture with MTZ 80 + BZTS - 1.0, cultivation MTZ-80 + ZBC - 300.

Before sowing, flaxseed seeds were subjected to air-heat treatment - heating for 3-5 days and etched with 80% TMTD. They started sowing when the soil warmed up at a depth of 10 cm to 6-8 degrees. C. The sowing rate was established in the amount of 22-24 million germinating seeds per 1 ha, which corresponds to the sowing rate of plant varieties resistant to lodging. Sowing was carried out by the MT3-80 + AMAZON D 9-30 unit.

The Floravit® CD was sprayed into the “herringbone” phase with a concentration of 1 · 10 ^-4 g / l according to the preparation, the plot area was 1 m ² , the location was randomized, and the experiment was repeated four times.

KD “Floravit®” is a complex of biologically active substances, the producer of which is the fungus Fusarium Sambusinum Fuckel F-3051D. The drug is obtained from the dietary supplement “Floravit®” (aqueous solution) by additional pasteurization and the addition of a sodium benzoate preservative. Floravit® CD contains organic acids (0.1-0.2%), polysaccharides (0.04-0.05%), sodium benzoate (0.1%) and water (up to 100%). KD Floravit® was registered on April 27, 2011, certificate of state registration, account series 77-2-4.1-4863, registration number No. ПВР-2-4.1 / 02705.

The soil is soddy-podzolic medium loamy, old arable, soil density 1.53 g / cm, humus content (according to Tyurin) 2.5%, P ₂ O ₅ (according to Kirsanov) 17.0 mg / 100 g, K ₂ O (according to Maslova) - 9.5 mg / 100 g, N easily hydrolyzed (according to Tyurin) - 5.0 mg / 100 g, absorption capacity - 19.4 mg.equiv./100 g, the amount of exchange bases - 9.7 mg. equiv / 100 g

Varieties of flax flax (Linum usitatissimum L.) - Antei (bred by the Pskov Research Institute of Agriculture), Toast-5 (bred by the Siberian Scientific and Research Institute of Agriculture and Agriculture of the Russian Agricultural Academy), all seeds of the PCT category were selected as the object of study.

Before sowing, the Kemira Field fertilizer was applied to the soil - 10, based on nitrogen (kg / ha a.a.), content: N - 11.8; P ₂ O - 12; K ₂ O - 25; S is 0.7; Ca - 0.55; B - 0.09; Fe - 0.16; Zn - 0.09; Mo - 0.008; Cu - 0.08.

For both flax flax varieties used, similar results were obtained for almost all measured parameters. The studies were conducted at the field experimental station of the Russian State Autonomous Institution-Moscow Agricultural Academy named after K.A. Timiryazev. The results of the experiments are presented in table 1 and table. 2.

5. Technical results

The technical results of the proposed proposal are to increase the yield of flax flax by 11-35%. At the same time, the characteristics of the plant are improved.
