The invention relates to agriculture, namely the method of cultivation of rice.

To obtain high and stable yields of agricultural crops requires the implementation of highly effective plant growth regulators, meet the requirements of modern technology and environmental protection. There are various ways to control the growth and development of crops with the use of natural and synthetic biologically active substances such as auxins, gibberellins, cytokinins, etc. (Shevelukha R.S. plant Growth and its regulation in ontogenesis. M.: Kolos, 1992). However, some of these substances are expensive, while others are not widely used because of insufficient stability, insolubility in water or relatively high toxicity (e.g. auxin). Therefore, the task of creating and using cheap, non-toxic, water soluble chemicals, acting as phytohormones, in extremely low concentrations, today is relevant. This problem is also relevant for the cultivation of rice, because rice is the staple food of the inhabitants of South-East Asia with a multibillion population (China, India and others)

Know the use of chemical growth regulators Furlan (RF Patent 2076866, publ. 10.04.1997), "Krasnodar-1" (Patent of the Russian Federation 2042675, publ. 27.08.1995) and their combination : the AI to enhance seed germination and increase rice yield in optimal dose of 0.001% (RF Patent 2178246, publ. 20.01.2002).

For pre-treatment of rice seeds proposed salt triazinetrione acid (kovaciny), improves germination and increase the length and roots of seedlings at a concentration of 0.01-0.0001 wt.% (RF patent 2083568, publ. 10.07.1997).

Know the use of growth regulator Emistim for the cultivation of rice in a concentration of 1-30 ml/t, and also in a mixture with the herbicide basargan M at a dose of 0.5-5 ml/ha (RF Patent 2262226, publ. 20.10.2005).

Known chemical regulator of growth and development of plants the Melafen, representing a melamine salt of bis(oxymethyl)phosphinic acid of formula I (RF Patent 2158735, publ. 2000.11.10).

The drug has low toxicity - LD502000 mg/kg in mice, 6000 mg/kg in rats. Aware of the impact of Melafen on germination energy and germination capacity of seeds to improve the yield and quality of spring wheat (yield increase by 6.2% at pre-treatment of seeds and 9.3% with additional spraying during the growing season). However, the applicability of Melafen for growing rice is unknown.

The objective of the invention is the expansion of the range of methods of rice cultivation.

The technical result is a new method that improves germination energy, germination, yield and technological characteristics of a grain of rice.

Technical result is achieved by the application is receiving the drug Melafen for a one-time pre-treatment of rice seeds. The results obtained here were unexpectedly high, especially when using the drug in a concentration of 110-5-110-8g/l, optimally 110-6g/l (or 110-7%).

Data on germination of rice seeds and the intensity of their germination depending on pre-sowing seed treatment with solutions of Melafen different concentrations obtained in laboratory experience. Data on the effect of Melafen on morphogenetic processes obtained in field experiments in Timashevsk and Slavonic districts of the Krasnodar territory.

Fig - grade estuary.

Circuit and method of laboratory experience:

control - soaking of seeds in water;

- experienced options - soaking the seeds in an aqueous solution of Melafen concentration of 110-3, 110-4, 110-5, 110-6, 110-7, 110-8, 110-9g/l

Exposure seed treatment with water (control) and the solutions of Melafen is specified concentration (advanced options): 1 hour.

Studies were performed in Petri dishes, a bed for the seeds of filter paper. In each Cup was placed on 50 seeds. Germination energy and germination of seeds was determined in the terms specified in GOST 12038-84: 4thday (germination) and 7thday (germination). Seeds were germinated in an incubator at 25C. the Repetition of experiments 4-fold. On the day the determination is FL seed germination was measured by the length of shoots and roots and were weighed wet weight (biomass) of roots and shoots and after drying dry mass.

Results

Data germination of rice seeds and the intensity of their germination depending on treatment before sowing solutions of Melafen different concentrations are presented in table 1. From the table, it is seen that the preparation of Melafen has a significant impact on the intensity of seed germination. The strength of effect on the germination process largely depends on the concentration of the solution.

All tested concentrations of the drug does not cause reduction of sowing qualities of seeds. The highest values of germination energy and germination, length of shoots and roots and their mass (wet and dry per 100 pc. seedlings) obtained by treating rice seeds at a concentration of 110-6g/l or 110-7% (91.7 and 95,0%, 9.0 and 5.1 cm, 2,809 and 3,120 g, 0.311 and 0,346 g/100 pcs. seedlings against 80,0 and 78.5%, 5.5 and 4.2 cm, and 2,063 2,591 g, 0,249 and 0,285 g/100 pcs. of seedlings in control).

Thus, the absolute values presented in table 1 indicators depend on the concentration of the solution of the drug the Melafen. The highest values of these parameters observed in the processing of rice seeds with a solution of Melafen concentration of 110-6g/l (or 110-7%).

Scheme and methods of field experience:

control - sowing seeds without treatment;

- experienced options - treatment of rice seeds in an aqueous solution of Melafen is at stake is entrale 110 -6g/l;

accounting square plots of 20 m2;

- repeated experience - 3x-4xfold;

- agriculture - common in the household.

Before cleaning with each repetition carry out selection of plant samples: 25 plants for the structural analysis of harvest (plant height, tillering, grain number in ear, grain weight and straw).

Rice yield was determined by actually removed the shaft seeds with every repetition.

The obtained data were processed by analysis of variance Bagasheva.

The yield formation of rice

The intensity of growth processes, primarily depends on the friendliness of the emergence and their ability to survive. Rice seeds have low field germination, resulting in lower yields. Treatment of rice seeds before sowing the growth regulator is a way to increase the germination rate, survival rate of plants, yield and quality of rice raw.

Presented in table 2 data shows that treatment of seeds with Melafen enhances plant growth in height (88,2 cm2in control - to 70.9 cm), leaf-bearing (area of leaves 264,7 cm, in control - 156.8 cm2), the growth of biomass (93,09 and 66,12 g/plant) and dry weight (25,34 and 14,75 g/plant, respectively). A significant difference in terms of leaf area of control and test options, the ants points to the fact, in the experimental apparatus is not only active listopadova, but the slow death of leaves. The latter is associated with higher viability of leaves in the experimental apparatus, and therefore, with the activation of the assimilation process, as indicated by the increased percentage of dry matter (27,2% versus 22.3% in the control). Growth intensification in the application of Melafen, more active accumulation of assimilates vegetative mass of rice plants and their outflow in reproductive organs significantly affects the formation of the elements of yield structure.

The crop is caused by three main elements:

- the number of productive stems, formed on the plant,

- number of grains per plant,

weight of grain per plant.

The data of table 3 show that the values of the three basic elements of yield structure was significantly improved in the variant with Melafen (productivity stems 2,4 pieces, in control - 1,45 pieces; grain number in ear 109,5 against 81,1 pc. control, grain weight is 5.07 against 2,34 g/plant in the control). In the experimental embodiment, the capacity of the accumulation of grain higher, as evidenced by the lower percentage of postoperati (in the experience of 13.7%in control 19,0%) and a higher harvest index (the ratio MZ/MS 0,93 against 0,80 in control).

Significant activation of morphogenetic processes in the application of Melafen leads to povyshenie yields. Yield increase (table 4) is 10.2 kg/ha or 20.1 per cent. In addition to increasing crop yields and improves the quality of raw rice (table 5). When using the Melafen is formed larger and aligned grains with a mass of 1000 grains 31.1 grams against 29,0 g in control and higher glassiness (experience - 90,5%in control - 84,5%).

Thus, as shown by the experimental data, a disposable pre-sowing seed treatment of rice preparation the Melafen not only leads to a significant increase of the energy of germination and germination of rice seeds (91.7 and 95,0% instead 80,0 and 78.5% in the control) and yield (60,9 kg/ha instead of 50.7 kg/ha in the control), but such technological characteristics of the products obtained, as the fracture (in the experience of 1.0% compared with 3% in the control), planchette (in the experience of 16.2% compared with 18.1% in the control), and improving the glassiness (90,5% compared to 84,5% in control).

The use of Melafen for the cultivation of rice is new, the results obtained it was not possible to predict on the basis of prior knowledge, and therefore the use of the drug the Melafen for cultivation of rice meets the criterion of "novelty", "inventive step" and "industrial applicability".
