Method POP.1, characterized in that after inserting the seSmn on the surface of the check, cutting of the drainage grooves is carried out.

Description

I11 The invention relates to a method of sowing and cultivating intermediate agricultural crops in irrigation, in particular in a rice irrigation system. The known method of cultivating intermediate crops, including agrotechnical operations in the cultivation of rice, pre-harvest discharge of water from a check, harvesting rice and sowing seeds of intermediate crops C. The disadvantage of this method is that due to the increased soil moisture it is not possible to prepare the soil for sowing intermediate crops and, moreover, preparing the soil and sowing in high humidity conditions requires a lot of money, labor and fuel. There is also a known method of cultivating intermediate crops, which includes agrotechnical operations for the cultivation of rice, pre-harvesting of water from a check and air seed of an intermediate crop, followed by harvesting rice crops from seedlings of intermediate culture 2J. The disadvantages of this method include the poor germination of seeds due to the presence of a film of algae on the surface of the check and significant damage to the seedlings of the intermediate culture by harvesting equipment. The aim of the invention is to increase the yield of intermediate crops. The goal is achieved by the fact that according to the method of cultivating intermediate crops during rice cultivation, including agrotechnical operations on rice cultivation, pre-harvest discharge of water from a check and aviaseiv intermediate crops, simultaneously with rice harvesting, the superficial rolling of the seed seeds followed by mulching them with chopped rice straw At the same time, after seed placement on the surface of the check, the drainage grooves are cut. Example. Nitrogen fertilizers (urea) are applied by plane at the rate of 90 kg dv. on the same hectare, on the same day, an intermediate crop (triticale) was planted in uncleaned rice. The seeding rate is 250 kg per 1 ha. The rice was harvested the next day by an Iseki combine harvester with simultaneous pressing of seeds into the soil using the tracks of a combine and an annular roller. When harvesting rice, the combine crushes rice straw and evenly distributes it to the surface of the check. In the known method, the seeds of the intermediate culture are sown in ripening rice after water is drained from the check for 10-12 days before the rice harvest. Harvesting is carried out on the seedlings of the intermediate crop according to the generally accepted technology, including cutting rice into rolls, after drying them (after 3-4 days) the 1st threshing, then after 1-2 days the 2nd threshing and harvesting of the straw is carried out. After the completion of the technological process, the state of crops is analyzed. Comparative data fto the yield of green mass and grass stand on 1 in the tractor track tracks between the tracks of tracks in accordance with the proposed and known methods are shown in the table. Analysis of the data in the table shows that the yield of green mass by a known method is higher than in the control, by 166 centners per hectare or by 87%.
