Method of sowing seeds of alfalfa and leban for pasture forage in arid zones
SUBSTANCE: method comprises planting grass mixtures of legume crops. The tillage to a depth of 20-25 cm, surface levelling and sowing seeds is carried out with inter-row spacing of 15 cm under the scheme leban-alfalfa-alfalfa-leban. In the first year of life in May, in the budding phase - the beginning of flowering, the alfalfa is harvested together with leban for hay. On the second year in spring leban is used for hay, and in winter it is grazed off by sheep or cattle. In other years leban is grazed off at the grassroots alternatively - in summer and in winter, with seeding rate of leban of 5 kg/ha, alfalfa - 6 kg/ha of seeds. Two-component mixtures of leban and alfalfa are sown in winter. For self-sowing of leban every two years grazing of leban is alternated in summer and the following year in winter.

The invention relates to agriculture, in particular to the creation of cultivated pastures.
Known "Method of creating cultivated pastures" (EN 2441358, publication date 10.02.2012), the method taken as a prototype. Method of creating cultivated pastures involves seeding a legume-grass mixtures forage grasses, consisting of Festulolium, white clover and alfalfa yellow. Sowing is carried out in two stages. In the first stage are sown white clover and Festulolium in the ratio 1:2 respectively. In the second stage seeded alfalfa yellow for 1.5-2.0 months to the end of the growing season of grasses. Alfalfa yellow sow in the amount of 20-30% of the seeding rate mixture of white clover and Festulolium.
The disadvantages of the prototype lies in the fact that the mixture of Festulolium, white clover and alfalfa yellow are designed for the Central black earth region with medium to light soils, where annual precipitation is over 600 mm of rainfall, while in the arid zone on chestnut and light chestnut soils in combination with saline drops 200-300 mm of rain per year. Therefore, Festulolium and red clover will take root in this region, need arid plants.
Common features of the prototype and of the invention: mixtures are legumes that enrich the soil with nitrogen.
The problem to be solved by the invention is the creation of a productive and long-grasslands in arid zones with environments�them and heavy saline and solonetzic soils.
Effect: invention allows to increase the yield of grassland crops and improve the nutritional composition of the soil due to the accumulation of rhizobia nitrogen in the soil.
This technical result is achieved in that carry out the sowing of mixtures of legumes are processing the soil to a depth of 20-25 cm, surface levelling and sowing with row spacing of 15 cm under the scheme chaste tree - Lucerne - Lucerne - the chaste tree. In the first year of alfalfa in may, in the phase of budding and beginning of flowering is removed together with brushwood hay, for the second year in the spring of Vitex used for hay and in the winter the vent sheep or cattle. In other years chaste tree pit at the root alternately in summer and winter, while the rates of seeding brushwood 5 kg/ha, alfalfa - 6 kg/ha of seeds, a two-component mixture of brushwood and alfalfa sown in winter. For samoobzhimnaya brushwood once every two years alternating etching brushwood in the summer and next year in the winter.
A two-component mixture of brushwood and alfalfa sown in winter. Winter crops brushwood with Lucerne succeed better and efficient use of winter and spring precipitation, thawing of soil, creating favorable conditions for seed germination and post germination of plants.
Alfalfa until the 20th of may gives one cutting and grows in �the time only for the next year. In the spring the first three years the bulk of feed makes alfalfa, and in summer, autumn - chaste tree. After cutting alfalfa with chaste tree, vegetation burn out. In adverse weather conditions, the major share of pasture forage is chaste tree.
The productivity of mixtures at medium, heavy salinized and alkaline soils of the arid zone are presented in the table.
Alternation of pastures of chaste tree in the summer and next year in the winter allows the brushwood once in two years smoovement, there are kids who give new plants and fill the aisles. Chaste tree Matures and develops seeds in the month of November. Eastern and Western winds seeds are scattered throughout the array. At loss of alfalfa on the 4th year pasture productivity and protein content in the feed is not reduced.
Eatability brushwood sheep and cattle 90-95%, it grows well in the autumn and gives green weight during the warm period.
Pasture herbage from chaste tree and alfalfa contributes to the maintenance of soil fertility and the accumulation of nitrogen in the soil to the rapid regrowth of plants drained of brushwood.

SUBSTANCE: method comprises watering using the system of mole drainage, flooding rice checks, mowing rice in rolls with two-three-fold threshing of rolls while leaving rice straw on the surface of the check. In autumn before fall ploughing the chemical ameliorant phosphogypsum is applied along with 60 t/ha manure on the surface in the dry state by spreading on the surface using spreaders. The ameliorant dose depends on the degree of soil salinisation: in case of the exchangeable sodium content of less than 15% 3-5 t/ha is applied, in case of 15-20% - 8-10 t/ha, and if it is greater than 20% - 10-15 t/ha. In spring the mole drainage of subsurface layer is carried out, the disease-treated rice seeds are sown in ordinary way. Then flooding of rice checks is carried out with water layer of 10-12 cm. In case of a very strong degree of soil salinity the originally created layer is drained after 2-3 days, and the checks are flooded again with fresh water, in the initial period of development of rice plants - from seed germination till emergence of 2-3 leaves, for the period of germination and seedling emergence (23-27 days) the water is drained and during this period dressing with fertilisers and growth stimulants is carried out, treatment with herbicides using aircraft is carried out. After the mass seedling emergence in phase of 2-3 leaves on the rice field layer of water of 10-12 cm is created again and supported up to tillering period, and then reduced to a level of 5-10 cm. If increase in mineralisation of water to 2 g/l in the check is recorded, its drainage and replacement with fresh water is required. In the early phase of booting the water layer is increased to 15 cm and kept to the end of the milk stage. In case of increasing of mineralisation of water its systematic replacement is carried out, then the water supply is stopped and by the beginning of full ripeness of grain the water is completely drained.
