Method of cultivation of grain cottage grass

Abstract

The utility model relates to the field of agriculture, in particular to plant growing, and can be used in the cultivation of a perennial grain crop - grain wheatgrass for the conditions of semi-provided and unprovided dryland in the southeast of Kazakhstan with an annual rainfall of 200-400 mm. The technical solution of the utility model is drought resistance and efficient use of moisture, improvement of soil condition, stable grain and feed harvest, as well as reduction of costs for annual seed purchase and implementation of agrotechnical measures during its cultivation. The said technical result is achieved by a method of cultivating grain wheatgrass, which includes, in the first year, primary autumn tillage, pre-sowing surface tillage, winter sowing with rolling, and post-emergence treatment with a herbicide in the spring. According to the invention, primary tillage is carried out in the fall after harvesting the preceding crop once by plowing to a depth of 22-25 cm. Pre-sowing surface tillage is carried out by loosening the surface soil layer to a depth of 10-12 cm, sowing of grain wheatgrass is carried out in the fall using precision seeders in a wide-row method with a row spacing of 50 cm to a depth of 1-2 cm with simultaneous rolling and application of phosphorus fertilizers ammophos at a rate of P60 per 1 hectare, in the spring during the tillering phase, post-emergence treatment is carried out with the herbicide Ballerina at a rate of 0.4 l / ha in a tank mixture with the growth stimulator Beres 8 at a rate of 0.2 l / ha, and in the tube emergence phase, inter-row soil cultivation is carried out at a depth of 8-10 cm with the simultaneous application of ammonium nitrate at a rate of N60; in the earing phase, as pests appear, grain wheatgrass crops are treated with a tank mixture consisting of the insecticide Karatoshans at a rate of 0.2 l / ha and the growth stimulator Beres 8 at a rate of 0.2 l / ha. An additional technical result is achieved by cultivating grain wheatgrass according to the invention. In subsequent years, ammonium nitrate is applied early in the spring at a rate of N60, followed by light harrowing to lock in moisture. As the grain wheatgrass plants grow and develop, protective measures are implemented.
