The way abalak of rice cultivation

 

(57) Abstract:

The invention relates to agriculture and can be used in the cultivation of rice and other grain crops grown in the conditions of irrigated agriculture. Pre-align the microrelief checks on stubble, hoe checks by ploughing and harrowing of winter tillage, produce layout surface. Before planting make a chemical means of weed control, and seeding is performed with simultaneous local application of mineral fertilizers. In the phase of growing season end of the milk - early dough stage of the crop is treated with a solution of mineral fertilizers with the addition of microdose amine salt of 2,4 D. In the early phase of tillering carry out the introduction of vegetative biomass Azolla in the amount of 3-5 kg per 1 hectare Proposed method allows to reduce the growing season and increase the productivity of rice. 8 table.

The invention relates to the technology of rice cultivation and can be used for a number of crops grown in irrigated conditions, Zemledelie.

Technology of rice cultivation at the present stage includes a well-defined set of operations and receptions, obukowin A. X.. Aleshin N. E. "Theory and practice of application of micronutrients in rice", Maikop, 1969, S. 313), providing pre-soaking the rice seeds in the solution of micronutrients such as Zn, Co, Cu, etc. Along with this option the make of various trace elements in the soil before sowing together with mineral fertilizers and silicon. The minerals used to make, cause druzhnost seedling and tillering of rice plants.

The disadvantages of the method are the overall duration of the vegetation period, regardless of the sort that leads to loss of yield when harvesting in adverse weather conditions. The use of micronutrients does not contribute to a significant increase in rice yield.

There is a method of rice cultivation, which consists in the treatment of rice plants with a chemical - Riboflavin (see, for example, and.with. 899033, A 01 N 63/00, 1982). By their chemical nature Riboflavin is a vitamin, competing with gibberellic acid for apparment flavins oxidase, is able to suppress its action that causes branching and, thereby, to strengthen the productive tillering, i.e., to increase the productivity of rice.

The disadvantages of this method are the high cost of PR is astani rice.

There is a method of rice cultivation, we adopted as a prototype (see, for example, and.with. 974950, A 01 B 79/02, 1982) consists in preparing the rice paddies on the ground with the preliminary alignment of the micro-relief checks on stubble; pre-sowing application of mineral fertilizers and herbicides, planting rice seeds pre-treated with substances that stimulate germination, initial Bay cheques permanent water layer; the lower layer of water after germination; the introduction of mineral fertilizers; the regulation layer on phases of the growing season of rice; the implementation of additional treatment of crops with a solution of mineral fertilizers with the addition of microdose (15 - 20 g) amine salt of 2, 4D with a solution flow rate of 50 to 200 l/ha in the phase of growing season end of the milk - early dough stage, constant water discharge at the onset of ripening grain; drainage checks, cleaning rice.

The disadvantages of this method of rice cultivation are the complexity of the complex technological operations harvesting rice in the optimal phases of the growing season of rice) terms due to the weak enabling climatic conditions in autumn, the need to give priority to the cultivation of varieties with the least period vegetatively task is achieved by at the beginning of tillering of rice in check make Azolla in the form of vegetative green mass. The Azolla water fern. During the growing season of rice to its full maturation of Azolla vegetates in check, increasing their biomass almost 600 times.

Example 1. Studies on the use of the fern - Azolla conducted in the field in 1995 - 1996, experimental irrigated area Unionise.

As object of research was selected rice Spalchik, the most widely used in the Krasnodar region. The vegetation period of 110 - 115 days. Resistant to lodging, pyricularia and soil salinization. Short, responsive to nitrogen fertilizer.

Carried out preliminary alignment of the micro-relief checks on stubble.

After reaching physical maturity soil plowing has been ploughed to a depth of 12 to 14 cm and have shallow tillage to a depth of 8 - 10 cm After drying of the soil was carried out by the layout of the surface of the check to the deviation from the mean plane does not exceed 5.0 see Then produced meats cheque peripheral grooves to a depth of 0.3 - 1.2 cm, cutting bestrustees drainage to a depth of 0.4 - 0.5 m After this was carried out by secondary tillage soil herbicide ordram 5,0 kg/ha of nutrient content, with the incorporation into the soil to a depth of 0 - 5 cm 2 - 1 day produced seed at the rate of 200 seeds - 210 kg/ha together with local application of nitrogen, in the amount of 80 to 85 wt.% and phosphate - full dose of fertilizers. Sowing was carried out on 28 - 30 April. Shoots were obtained when shortened flooding regime. When the rice plants 2 to 3 leaves were made 15 to 20 wt.% nitrogen fertilizers and created a layer of water 5 to 7, see

In the beginning of tillering rice contributed vegetative biomass Azolla in the amount of 0.4 kg per check, with an area of 1 ha

This recorded the occurrence of individual phenophases of rice in the control conditions (growing by the method prototype) and in the experiment.

The results are shown in table. 1 and 2.

Example 2. All process operations similar to those described in example 1, but at the tillering stage of rice contributed vegetative biomass Azolla in the amount of 3 kg per 1 hectare presents experimental Results with table. 3, 4.

Example 3. All process operations similar to those described in example 1, but at the tillering stage of rice contributed vegetative biomass Azolla in the amount of 4 kg per 1 hectare experimental Results are presented in table. 5, 6.

Example 4. All process is between 5 kg per 1 hectare The results of the experiment are presented in table. 7, 8.

As can be seen from the results of the experiments presented in examples 1 to 4, the best is example 3, in which at the tillering stage of rice contributed vegetative mass Azolla in the amount of 4 kg per 1 ha of the Proposed method in comparison with the known allows you to shorten the growing period of rice for 7 to 10 days and to increase the productivity of rice in 1.5 times.

Method of rice cultivation, including a preliminary alignment of the micro-relief checks on stubble, soil checks by plowing and tilling of winter tillage, leveling checks, pre-making chemicals to control weeds and planting seeds with simultaneous local application of mineral fertilizers, processing crops in the phase of growing season end of the milk - early dough stage with a solution of mineral fertilizers with the addition of microdose amine salt of 2,4-D, characterized in that in the early phase of tillering rice carry out the introduction of vegetative biomass Azolla in the amount of 3 - 5 kg per 1 hectare
