The method of rice cultivation

 

The invention relates to agriculture, particularly the cultivation of rice. The method includes the supply of water from the dispenser on the rice fields, the outflow seepage from checks in the card discharge channels, re-use water filtration for checks flooding through vodopodyomnaya and application of nitrogen fertilizers and herbicides. Re-use water filtration is carried out with the beginning of the growing season of rice, with filtration of water before reuse mixed in water site with water from the dispenser in the ratio of 1:3. The method allows to increase the yield of rice due to the efficient use of fertilizers, herbicides and water resources, improve the quality of irrigation water and optimization of reclamation state of the system. 2 Il.

The invention relates to agriculture, particularly the cultivation of rice.

There is a method of irrigation of rice in which reuse discharged from the surface of cheques water (ed. St. USSR 1115665, class A 01 G 25/02, 1984 ). In this way local distributors and card sprinklers are used at the same time and by dumping, which is achieved by using control structures. Mobile Nason is the group's net irrigation water and its supply to the sprinklers. Drainage network consisting of card drains and district collectors, drains prefiltermessage water from checks.

With obvious savings net irrigation water the disadvantages of this scheme are the following provisions: for desalination drainage and wastewater collector fueled by clean irrigation water, which results in an increase in the drawdown of the network and, as a consequence, in the soil of the check start to flow anaerobic processes, negatively affecting the development of plant rice; significant capital and energy costs, as drain-waste-water serves for irrigation pumping stations.

Also known rice irrigation system "Kuban" (see A. D. Kombarov, A. S. meadow, A. C. Serbin "rice Irrigation system. M: "Kolos", 1994, S. 189). Typical system module contains a local distributor, laid-axis fields, sewers and drains, located on the borders of fields, six of these plots, each containing four of the cheque, canals and hydraulic structures on canals and roads.

The disadvantage of this rice system is something that is not provided resource-saving technology of rice (reuse of drainage and wastewater).

The known method virusiv the Idov and translation card release channels in the mode of backwater, when prefiltermessage of checks in the card discharge channels water return back to checks by auxiliary vodopodyomnaya.

Under this system of rice cultivation provides a more complete and efficient use of fertilizers and herbicides, along with savings of irrigation water by filling cheques water release channels.

However, when watering the rice discharged water must carefully monitor the salinity of irrigation water. Plant rice may develop at a fairly high salt content in irrigation water. But when sulphate salinity, when the salt content in irrigation water is above 4 g/l, and chloride at 2 g/l, they have a detrimental effect on plants is the inhibition of root system.

Use water drainage and discharge network for growing rice is possibly subject to dilution with clean irrigation water from the feed channels. The ratio of net water recycled and reused in different periods of the growing season of rice fluctuates and is approximately 30%.

Technical solution to the problem is to increase rice yield through efficient use of fertilizers, herbicides and water resources, improve the quality of orositelnaya rice, including the supply of water from the dispenser on the rice fields, the outflow seepage from checks in the card discharge channels, re-use water filtration for checks flooding through vodopodyomnaya and application of nitrogen fertilizers and herbicides, reuse water filtration is carried out with the beginning of the growing season of rice, with filtration of water before reuse mixed in water site with water from the dispenser in the ratio of 1:3.

The novelty of the claimed proposal due to the fact that under this system of rice cultivation reuse of drainage water card and waste channels occurs from the beginning of the growing season of rice, improves the quality of the water supplied to checks, hydraulic drop dispenser-check provides the required for the operation of the water lift difference, there is no need to create a backwater card release channels, which improves the reclamation condition checks.

According to the patent and scientific literature is not found similar aggregate characteristics that allows to judge about the level of invention proposals.

The invention is illustrated by drawings, where Fig. 1 shows a diagram of the module of rice Oros is n, the hydropower site.

The method of rice cultivation is as follows. In rice irrigation system drainage outflow seepage water comes from checks 1 in the card discharge channels 2. And already from the beginning of the growing season of rice reuse for irrigation water from the card discharge channels 2 through lifting unit, which consists of Autonomous water lift 3 provided with kartavyam sbresny channel 2 through line 4.

From the distributor 5 through line 4, is laid in the dam embankment of the distributor 5, water is supplied to cheques 1, this creates a hydraulic gradient that provides Autonomous water lift 3, and the water lift 3 returns water from the waste channel 2 checks 1.

As water plants can be used offline piston vodopodyomnaya (decision on granting of the patent of the Russian Federation on Z. 97103801/13 from 02.02.98). Not excluded the application of Autonomous vodopodyomnaya and other structures.

Insufficient filtration water flow check 1 in the card discharge channels 2 water can be supplied from district collector 6. This requires the installation of retaining structures 7 at the point of confluence of the district collector 6 in the economic manifold 8.

For predot four level control 10.
