METHOD FOR JOINT CULTIVATION OF SPRING AND WINTER GRAIN CROPS Russian patent published in 2022 - IPC A01G22/20 A01B79/02 A01C7/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The method includes sowing and harvesting, while a spring grain crop mixed with a spring leguminous crop is sown using the strip farming method with a winter grain crop with a strip width of at least 5 cm and a distance between the strips of one crop of 22.5-30 cm. Spring grain and leguminous crops are also sown in strips with a strip width of 4-6 cm, with one row with winter crop seeds in the gap between the spring strips. When harvesting spring crops, straw is scattered over the stubble uncut or crushed, after the comb it is left with a stem, in winter grain, straw is scattered crushed. Seeds of winter crops are sown with fertilizer or grass-sowing apparatuses, and spring seeds are sown with grain apparatuses, seeders of the type SUZT-4 and SUZT-4T or converted seeders of the class SZU-3.6, SZP-3.6 with the installation of single-disc anchor coulters with a seeding strip width of 4-6 cm, as well as a seeder of the type SKP-2.1 “Omichka”. Crops are harvested for livestock feed.

EFFECT: method provides the implementation of joint cultivation of winter cereals with spring grains and leguminous cultures, soil mulching and weed suppression, with the possibility of effective technical implementation of simultaneous sowing of seeds of spring and winter crops using serial sowing machines for strip sowing, as well as, new or converted for narrow-strip sowing, grain-fertillizer disc sowers, increasing the yield and quality of grain and feed, reducing the cost per unit of production with the gradual restoration and maintenance of the fertility of the fields without the use of fertilizers and other chemicals.
