METHOD OF ORGANIC RICE CULTIVATION Russian patent published in 2018 - IPC A01G22/22 A01B79/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to rice growing. method includes harvesting a precursor, tilling, seeding the seed with a spreading method, flooding the checks and regulating the water layer. As a precursor, an agricultural crop is used to ensure the nitrogen accretion in the soil, improving its physical characteristics and biological processes in the root layer, for example soy. After harvesting the precursor, plowing is carried out. If the soil is clean without leies, then disking and check planning are carried out with accuracy of ±5 cm. Then moling through not more than 5 m and provocative watering of rice bays are carried out. After drying and germination of weeds, the cultivation is carried out until an aggregate structure of the soil is obtained, after it is dried naturally, and sowing is carried out on May 20–25. Next, it is flooded with a layer of water for 10–15 cm and at the end of the phase of germination of rice seeds, the water layer is raised to 25 cm. At the same time, a weed germination, a rice patch, is observed and at the beginning of the death of its leaf sheath, the layer of water is reduced to 10–12 cm, providing its precision regulation before the dough stage of rice.

EFFECT: method allows to reduce labor input and energy consumption when cultivating organic rice.
