RU2277323C1 - Method for protecting of winter crops from getting wetted - Google Patents

Abstract

FIELD: agriculture, in particular, plant growing.

SUBSTANCE: method involves wetting seeds one day before sowing for 15 min in warm (20-30 C) 0.02 M solution of praline amino acid; slightly drying seeds on screen in well ventilated room; after sowing procedure, providing pregermination slitting of winter crops by means of slitter; during initial thaw period, upon transition of daily average temperature past 5 C, treating young crop with aqueous solution of praline mixed with saccharose, said solution being prepared at the rate of 100 g of amino acid and 300 g of saccharose per 100 l of water, at liquid consumption of 50 l/hectare. Liquid sprayer is used for treatment of young crops.

EFFECT: increased efficiency in protecting of winter crops from excessive wetting.

Description

The invention relates to the field of agriculture / crop production / and can be used to increase the resistance of winter crops to soaking.

It is known that winter crops flooded with melt water die as a result of depletion, since during anaerobic / oxygen-free / respiration, the consumption of reserve substances / carbohydrates / increases significantly [1].

Methods have been developed to prevent the soaking of winter crops, which include autumn pre-emergence slitting or vertical drainage. To do this, in low parts of the field, several wells are drilled to waterproof sandy soil through which melt water flows [1].

There is also information that, when flooding in plants, the content of free proline increases, the accumulation of which is considered as one of the ways of adaptation of plants to life under conditions of hypoxia [2].

Using these patterns, we have developed a new, more effective than the existing method of protecting winter crops from getting wet, which, along with autumn pre-emergence sowing, provides for pre-sowing seed soaking in an aqueous solution of proline amino acid and treatment of plants at the time of enhanced thawing of the soil with an aqueous solution of proline and sucrose.

The purpose of the invention is a significant increase in the effectiveness of protecting winter crops from getting wet.

For this, the day before sowing, the seeds of winter crops are soaked for 15 minutes in a warm / 25-30 ° C / 0.02 M solution of the amino acid Proline and after drying on the canopy in a well-ventilated room, they are sown.

After sowing, with the help of cheresez, pre-emergence sowing of winter crops is carried out.

With the onset of the thaw, when the average daily temperature passes through 5 ° С, the crops are treated with an aqueous solution of proline mixed with sucrose prepared at the rate of 100 g of amino acid and 300 g of sucrose per 100 g of water. Liquid consumption during processing is 50 l / ha. Processing is carried out using a liquid spray.

The results of the assessment of traditional and new methods of protecting winter crops from getting wet are presented in the table.

The survival rate of plants when wet,% Culture control / unprotected / traditional way / slotting / new way Winter wheat 73 79 86 Winter rye 82 66 94 Winter barley 68 75 78 Triticale winter 79 84 90

An analysis of the comparative evaluation of the results confirms the higher efficiency of the new method, where the survival rate of winter crop plants in the conditions of soaking increases by 10-13%, while when using the traditional method this indicator decreases to 4-7%.

The proposed method is intended to be used in winter crops.
