METHOD OF INCREASE OF THE FERTILITY OF SOIL IN THE RICE CROP ROTATION

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agriculture, in particular to the cultivation of rice. Method comprises sowing soybean seeds treated with "Rizotorfin" in rice rotation by alternating with rice for any number of years. In this case, before sowing, soybean seeds are treated with a working solution consisting of the preparation "Rizotorfin" in an amount not exceeding 180 ml and the growth regulator "Melafen" in an amount not exceeding 1 ml per 1 liter of non-chlorinated water, and the treatment of soybean plants in the branching phase is carried out with an aqueous solution of the growth regulator "Melafen" with a concentration of 10^-9 % in an amount of 5 ml per 200 l/ha aqueous solution. After harvesting the soybean, its stubble remains are plowed into the soil.;EFFECT: method makes it possible to increase soil fertility in rice crop rotation.;1 cl, 2 tbl, 3 ex
