RU2124285C1 - Seed clover herbage desiccation method - Google Patents

Abstract

FIELD: agriculture, may be employed during harvesting of legume grasses with the usage of chemicals. SUBSTANCE: method involves treating young crops with desiccant, such as reglon, at the phase, when 75-80% of clover heads are browned; harvesting crops by combine. Desiccant is taken in an amount of 2-2.5 kg/hectare and mixed with cutting liquid taken in an amount of 10-1 l/hectare. Such ratio of components allows toxic load of seed herbage to be reduced. EFFECT: increased efficiency by utilizing industrial wastes, reduced usage of desiccant and improved environment control. 1 tbl, 2 ex

Description

 The invention relates to the field of agriculture, in particular chemical agents used in crop production, and can be used in the harvesting of legume seeds.

 There is a known method of desiccation, where crops before harvesting at seed moisture of 34-40% are treated with chemicals, in particular liquid nitrogen (ed. St. 897164, A 01 G 7/06, 1982).

 In the known method, liquid nitrogen disrupts the vital activity of the root system of legumes, the activity of nodules on the roots of legumes decreases, and as a result, the grass stand is thinned out or completely falls out.

 As a prototype method, we can consider a technical solution in which the seed areas are treated with desiccant Reglon at a certain moisture content of the grass stand at a dose of 3-5 kg / ha (Akchurin M.M. et al. Dysification of meadow clover. Plant Protection Journal N 7 , 1987, p. 40, 41).

 The disadvantage of the prototype method is that the drug in such doses is toxic, which adversely affects the environment, especially on pollinators of legumes nesting in seed grass.

 The purpose of the invention is to reduce toxicity and preserve the environment.

 This goal is achieved by the fact that, in contrast to the known method, a half dose of desiccant raglon is used in a mixture with coolant (lubricating coolant is an industrial waste).

 The method is as follows.

 Reglon-disicant for harvesting testes of herbs is taken in half dose - 2-2.5 kg / ha (required rate) and mixed with coolant in an amount of 10-12 l / ha. Above these parameters, the coolant is not effective, since the oleic acid contained in it negatively affects the environment.

 Coolant (lubricating coolant) contains oleic acid 1.5%, spindle oil - 9%, triethanolamine - 0.5%, metals (zinc, copper, etc.) up to 0.5%, the rest is water. The oil contained in the coolant contributes to the better adherence of the desiccant and enhances its effect in the dehydration of plants. Oleic acid enhances the effect of reglon. The mixture is dissolved in water and the clover crops are treated in the drilling phase of 75-80% of the heads. After 4-5 days carry out cleaning.

 In experiments conducted on the experimental basis of the institute, it was found that the composition (diluted in 300 l of water - hectare norm) does not have a negative effect on the microflora of the soil. Seed germination after treatment with such a mixture did not decrease.

 The use of the new desiccant allows cleaning without loss while recycling industrial waste.

 Example 1. In the phase of browning of the seed grass stand of clover meadow (75% of the brown heads) per 1 ha, a solution was prepared: reglon 2 L and coolant 10 L. The mixture was thoroughly mixed in 300 l of water and the crops were sprayed with a GAN aggregate. After 5 days, the Niva harvester was harvesting. The yield from the experimental plot amounted to 2.2 centner / ha, and in the control (without disecant) 0.8 centner / ha.

 Example 2. The experiment was carried out, as in the first example, with the only difference that they took 2.5 kg / ha of reglone and 12 l / ha of coolant.

 The experimental data are summarized in table. In the control (without desiccant), the yield was 0.8 c / ha with a heap moisture content of about 40% and seed germination rate of 92%.

 The proposed mixture allows to reduce the toxic load in the seed grass, to utilize industrial waste, to increase the efficiency of the method, to reduce the cost of desiccant by reducing the amount of expensive reglon used and to preserve the environment.

Claims (1)

 The method of desiccation of clover seed grass, including the treatment of crops with desiccant Reglon in the drilling phase of 75 - 80% of the heads, followed by combine harvesting, characterized in that the desiccant is used in half dose of 2.0 - 2.5 kg / ha in a mixture with a lubricating coolant in the amount of 10 - 12 l / ha.
