Method of rice cultivation

 

(57) Abstract:

Usage: refers agriculture, in particular, to methods of rice cultivation. The inventive method of rice cultivation involves sowing seeds, the flooding of 25 - 30 cm and regulation of the water layer, thus sowing carried out randomly by the way, the layer of water 20 - 30 cm to support the emergence of seedlings 5 cm, after which the water dumped on 1 - 2 days, then the water layer increases up to 20 - 25, see table 2.

The invention relates to agriculture, in particular to methods of rice cultivation.

There is a method of rice cultivation Technology of rice cultivation. Methodical instructions. M. Kolos, 1983, S. 62), which includes fall, spring and pre-sowing soil preparation, seeding the flooding layer of 0.1 0.12 m, the water discharge naklevyvaniya seeds, re-flooding of the layer of 0.12 0.15 m after the emergence of seedlings of rice for the first sheet, and then a seedling corn Buntings no more than two leaves, but in such a way that the layer of water above the height of seedling weeds not less than 0,05 0,07 m, the lower water layer to 0.05 m after gibelli weeds, with the emergence of Fig 8 sheet prior waxy water level increase in the receipt of 0.1 0.12 m, the water flow stops in cecba are a low percentage of field germination of seeds, the presence of weeds, reduction in yields, high energy and labor.

There is a method of rice cultivation in the so-called shortened flooding (Recommendations by the technology of rice cultivation in the zone of the Azov marshes. Krasnodar, 1983. S. 39 40), including tillage, planting rice, Bay cheques water immediately after sowing, the water layer 0,05 0,07 m water discharge after naklevyvaniya seeds, processing of dried crops with herbicides and the subsequent flooding water 0,12 0,15 m after 48 h, the lower layer of water in the early phase of tillering up to 0.05 m, and at the end of tillering creating a water layer of 0.20 - 0.25 m, which is then reduced to 0.1 0.12 m and is maintained at this level until the early dough stage of grain with a subsequent reset.

The main disadvantages of this method are the need of the use of herbicides; low seed germinability (40 50%) inhibition of rice, because the break in the flooding leads to massive amounts of weeds, which is rapidly overtaking in the growth of rice, high energy and labor.

There is a method of rice cultivation [1] we adopted as the prototype, including pre-sowing soil treatment, planting rice in the furrow, sealed walls, for which their water supply to natural depletion of the water layer (lower) due to evaporation and filtration to a depth of 0.08 to 0.12 m so, to the upper part of the leaf rice was above the water, as the plant growth enhancing layer of water to 0.15 to 0.25 M. the disadvantages of the method are: low survival rate of plants, as under a layer of water 0,20 0,30 m (deadline 25 - 30 days), without a well-developed roots (lack of oxygen) and a large leaf surface, emerging from coleoptile and nutrients seed, rice POPs up and washed ashore, reduced productivity, high energy and labor.

The objective of the invention yield increase due to a higher percentage of field germination, reduce energy and labor costs.

For this planting carried out randomly by the way, cheques flood water 25 to 30 cm until the seedlings are 5 cm (8 to 10 days), after which the water dropping on the 1st 2 days. As lowering of the water layer increases the flow of oxygen to the plant, which helps to stimulate growth, strengthening the root system of flooding of rice, as well as the beginning of the sprouting corn Buntings. Then checks flooded with a layer of water 20 to 25 cm (7 to 9) up to the total loss of corn Buntings, then reduce the layer of water 5 to 10 cm to mass tillering, as plant growth layer of water is increased to 20 see

Comparative analysis of the prototype m flooding the water layer 25 to 30 cm until the seedlings are 5 cm and the total water discharge for 1 2 days with subsequent flooding 20 25 see Thus, the proposed solution meets the criterion of "novelty."

Comparative analysis with the known solution showed that receive discharges from those in 2 days after naklevyvaniya rice seeds known (Recommendations by the technology of rice cultivation in the zone of the Azov marshes. Krasnodar, 1983, S. 39 40), but it is used for treatment of crops with herbicides against corn Buntings. In the proposed method, the receiving water discharge from checks is used to saturate the soil with oxygen, stimulate growth and strengthen the root system of rice germination, corn Buntings, resulting in increased seedling density, increases productivity, reduces costs and allows to make a conclusion about conformity of the offered invention, the criterion of "inventive step".

The method was tested in elite seed farm "Red" S=808 ha Control served as a way of sowing in the open furrow with a constant regime of flooding at S=61 hectares

Method of rice cultivation involves the following sequential operations.

1. After ploskoreznaja tillage to a depth of 14 cm PCN-3,6, packing, discomania, undertake sowing of rice planter NRC-0,5, allowing the OS is relevant for the rolling of heavy wheels.

2. Cheques flood layer of water 20 to 25 cm 8 10 days until seedlings of rice 5 see

3. Water discharge completely in 1 to 2 days.

4. Cheques flood layer of water 20 to 25 cm 7 9.

Records of seedling density on the test sections was carried out within the framework of size 0,h,5 m which were placed along the diagonal through 50 m Records showed that seedling density on crops under the proposed method was 600 plants per m2and the prototype method 400 plants per m2.

Yield, respectively:

73,8 kg/ha and 59.5 kg/ha.

The cost of 1 hectare: 917988 RUB 1171265 RUB Cleaning finished 10 days earlier.

The main advantages of predlagaemogo method are:

the yield increase of 14.3 kg/ha due to the large density of rice plants is associated with a high percentage (70%) field germination of seeds;

reducing the cost of cultivation of rice on 153277 RUB/ha;

eradication of weeds;

the reduction of the vegetation period by 10 days.

Method of rice cultivation, including planting seeds, the flooding of 25 to 30 cm and regulation of the water layer, characterized in that the planting carried out randomly by the way, the layer of water 20 20 25 3O see
