Description

The invention relates to agriculture, in particular to the technology of growing rice.

The purpose of the invention is to improve the quality of grain and reduce environmental pollution.

PRI im p .ol 3 Comfort variety of rice So 1 Yarie. Sor. t. refers to the early ripe group with a growing season of 80-90; day. Plant height is 70-75 cm. The variety is resistant to lodging, and the effect is relatively resistant to disease. The soil of the black earth-black-diarus loam is a complex with solonetz (up to 15%). The predecessor is Spalchik rice variety.

After harvesting the precursor and cleaning the check in the autumn, the soil is planted over the stubble, after which a full dose of mineral, for example nitrogen, fertilizers is administered once in an amount of 120 kg a.v. on 1 hectare with the simultaneous loosening of the soil to a depth of 5-6 cm and the incorporation of fertilizers, for example, using the BD-3.0 + + ZBZTS-1.0 aggregator with subsequent soil rolling, for example, a smooth roller of the type MB-6.0 + ЗККШ- 6 In the soil prepared in this way, an intermediate crop, such as triticale, is introduced into the soil of a CZ-3.6 type grain crop, for example, at a seeding rate of 200 kg per 1 hectare, 5-6 cm deep, and cut the inner tricycle mass is cut at the beginning of the month, and then the secondary surface loosening of the soil, cutting of the intracellular grooves and flooding the check with a water layer of 8-10 s, which is maintained for 4-5 days, after which the water from the sbr check

sygeat After the mass emergence of weeds, weed-field and red-grain forms of rice, the seeds of which were in the soil, at the beginning

The month of June was carried out by the destruction of these weeds, by harrowing to a depth of 5-6 cm, and when a temperature of 19-21 ° С was established in a layer of soil 5-10 cm thick, the seeds of early-ripening rice were sown in checks with embedding to a depth of 1- 2 cm. After the mass germination of seeds at the end of June, the check is flooded with a water layer of Ø-12 cm, which is maintained until the second leaf appears in rice plants, and then the thickness of the flooding layer is reduced to the appearance of these leaves above the water.

At the age of 3–4 rice plant leaves, the layer of water is maintained at a level of 5–6 cm, and at the age of rice 5–6 leaves are grown to 10–12 cm. This layer of water on the check is maintained until the rice growing season.

ripeness of grain. At the same time, the remaining plants of weed-field forms of rice are in the milky ripeness phase of the grain. Under these conditions, water is discharged from checks

their implementation and harvesting of rice, for example, direct combining.

The yield of rice by tending the proposed method is 4.56 t / ha, the yield of cereals from 1 ton of grain is 3.19 tons. Weed and field forms of rice and weeds are absent from the yielded area.

The method allows to improve the ecological situation of the irrigation system by eliminating the use of chemical means of controlling weeds, pests and diseases.
