The invention relates to agriculture, in particular to methods of rice cultivation, and can be used in the cultivation of rice.

Biological productivity of rice fields depends on many factors. The main factor is the density of seedlings of rice and water regime, as well as seeding depth at sowing and the associated degree of lodging of rice plants before harvest.

In the far East, the most widespread method of rice cultivation with a minimum placement of seeds at a depth of 0.5-1.0 cm and intermittent water regime.

In a similar fashion cultivated rice in the Kuban region, but the seeding depth is within 1-2 cm

There is a method of rice cultivation, including planting rice to a depth of 1-2 cm, if the sowing is carried out in the early stages, the seeding depth 4.5 cm After planting depth of 1-2 cm carried out the initial flooding. After naklevyvaniya grain water with checks dumped on the germination of rice. During the emergence of the rice 1-2 leaves checks again pour water layer 12-15 cm, which support up to complete destruction of weeds. Further, this layer of water to support the early dough stage of grain. After that, the water flow stops, and the remains of her dropping gradually, in order to harvest the field was drained. (Agronomy journal. The cultivation of rice is under intensive technology. M: Rosselchozizdat, 1987, p.18-24).

The disadvantages of this method is the low seed germinability and susceptibility of rice plants to lodging, which leads to a partial loss of the crop.

There is a method of cultivation of agricultural crops in rice irrigation systems, including the formation of new ridges by tube expansion generated in the previous year. Moreover, the formation of the ridges is performed with the orientation of their predominantly in the direction from East to West, and in the transverse direction after conducting Diablo rice crops cut slits in increments of no more than 50 meters After this box, fill it with water, the level of which is supported at the level of the top shelf of the ridges. Next, the rice cultivation is done according to the traditional scheme. The way to increase the yield by 20-25% compared with the traditional methods of rice cultivation (RF patent No. 2159528, AV 79/02, AS 7/00, publ. 2000.11.27).

Disadvantages - inefficient use of cultivated land between crests of empty space. Due to the fact that the original Bay solely at the height of the crest, there is a mass germination of weeds and required additional treatment for their destruction.

In addition, the rice plants in raised bed planting more prone to lodging, resulting in part of the harvest is lost (polegshey the rice nevoso is but to remove harvester).

Closest to the claimed method of rice cultivation, including planting seeds randomly way, the subsequent flooding of crops water 25-30 cm for 8-10 days until the seedlings are 5 cm, then the water dropped to 1-2 days. Then checks again flood the water layer of 20-25 cm for 7-9 days for killing weeds, then reduce the layer of water up to 5-10 cm before the mass tillering rice, hereinafter referred to as plant growth layer of water is increased to 20 cm (patent RF №2099934, A01G 16/00, A01 W/02, publ. 27.12.1997 year).

Disadvantages - low germinability of seeds due to the destruction of seeds fungal diseases, because seeds are not embedded in the soil, lay on its surface and mold fungi actively affect the seeds.

It is known that dampness is a good medium for the propagation of fungi and flooding of crops for a long time provokes the development of moulds, which, ultimately, leads to low seed germination and consequently lower yields.

In addition, maintaining the water layer in check for a long time reduces the access of oxygen to the germinating seeds, which also adversely affects plant development and subsequently cause lodging of rice during maturation and as a consequence to a partial loss of the crop.

The objective of the invention is the rice yield increase and decrease of losses of grain during the harvest.

The task is solved in that the generated method, including planting seeds at a depth of 2.5-3 cm, subsequent flooding for 3-5 days and repeated flooding in the stage of 2-3 leaves of rice seedlings.

The technical result is an improvement of conditions for soil moisture germinating seeds in order to increase their germination and increased resistance to lodging of rice before the harvest.

The technical result is achieved by the fact that in contrast to known methods in the proposed method:

the depth of seed placement in the soil provide a depth of 2.5-3 cm;

- the duration of the initial Gulf of crops depending on sowing time (soil temperature at seeding depth) is reduced by 3-5 times compared with traditional technology, i.e. with 10-15 days to 3-5 days.

As a result, the germination and yield of plants at the surface occurs when constantly declining naturally soil moisture from 100 to 50% of field capacity.

The placement of seeds in the soil to a depth of 2.5-3 cm is the ideal to ensure seed to soil moisture.

The specified depth holds the germinating seed, it is not washed off during subsequent flooding, which contributes to greater seed germination and provides maximum seedling density. This forms a strong tillering node RA is the shadow, that increases the degree of resistance of rice plants to lodging and cleaning almost all going to the harvest, which in turn leads to an increase in grain yield.

For the guaranteed supply of sprouting seeds moisture, i.e. namachivanii rice seeds, carried out directly in the field by flooding checks for 3-5 days. Water in cheques fill in to cover it with soil.

Such flooding is not possible to develop mold fungi, provides access of oxygen from air, which allows to actively develop the plant and to build a strong tillering node.

The flooding water for 3-5 days provides the necessary soil moisture to obtain dense shoots without additional watering irrigation, which significantly reduces the cost of labour in the cultivation of rice.

Test method for Coastal research station rice showed good results on rice yield.

The table shows the accounting data of seedling density of rice cultivated claimed process in 2007

*) the figures in parentheses are the duration of the initial Gulf planting rice with the placement of seeds at a depth of 0.5-1.0 cm, days.

Data analysis the table shows that if we take the density of seed control option for 100%, it is obvious that the germination of the seeds at planting rice in the claimed method, depending on the sowing date on 20-76% higher.

This allowed us to harvest rice 10.8-13,6 kg/ha more than the yield of rice grown in the traditional way. So the yield of rice by the claimed method 40.6-52,3 the/ha depending on the sowing date, and the traditional way 29,8-38,7 kg/ha

Thus, the claimed method of rice cultivation, tested in practice, confirms the possibility of solving problems - increased rice yield and reducing the loss of grain during the harvest.

The method is as follows.

After pre-treatment soil (provoking the germination of weed seeds and their destruction by mechanical means) carry out sowing of rice seeders NWS-3,6 with a depth of 2.5-3 see After sowing checks pour water for 3-5 days for soil moisture required for the swelling of the seeds. Then the water is dumped on the germination of seeds with the release of plants on the surface, which is carried out when soil moisture is below field capacity. At the stage of emergence of 2-3 leaves in plants crops again pour water to a depth of 10-12 cm water Level maintained until stage dough stage of grain. Before cleaning the water is completely discharged, allow to dry out the soil and then carry out the harvest.

The advantage of the proposed method is to reduce the cost of production of agricultural work - there is no need for time-consuming extra moisturizing irrigation.

In addition, this method of rice cultivation, which reduces the possibility of destruction of plant fungal diseases.

The method alone is Denmark rice, including planting seeds, flooding with subsequent discharge of water on seed germination and re-flooding, characterized in that the seeding is performed with the placement of seeds in the soil to a depth of 2.5-3 cm, and flooding of checks carried out on 3-5 days for seeds by soaking.
