The invention relates to the field of agriculture, particularly crop production, and may find application in the cultivation of leguminous forages for seeds on slope lands.

There is a method of cultivation of legumes, which are feeding grass seed micronutrients (patent 2189719 published 27.09.2002, IPC A01C 21/00).

However, in the known method of feeding is carried out on the second year of life of the grass, and after harvesting the seeds is the loss of plants. Especially this process is enhanced in sloping lands, which reduces the efficiency of the method.

There is a method of cultivation of legumes, which carry out the planting of two crops of clover and alfalfa in the ratio of 1:1 in a clean non-coated sowing (patent 2155463 published 10.09.2000, IPC A01B 79/02).

The known method is not enough perfect, as sown simultaneously two cultures oppress each other when sown with the loss of clover on the 3rd year of life. On sloping lands in the first year of life, when perennial grasses are not well developed, observed erosion processes.

The closest technical solution is a technique in which the sow two kinds of leguminous herbs: red clover and clover are similar. While the clover sown in wide-row (85-90 cm), and the rows are sown clover similar (patent 2088065, about oblikovano 27.08.1997, IPC A01B 79/02).

The disadvantage of the prototype is that in the first year of life clover wide-row method of sowing overgrown weeds, and inter-row processing of crops contributes to erosion of topsoil layer. When overseeding clover similar next year it is impossible to get seeds at one species. In addition, on slope lands clover species podshuveyt into the turf to reduce erosion processes.

The technical result is the increased productivity of legumes in the joint crops.

A technical solution is achieved in that the clover sown in a continuous way the predecessor of winter crops after the first cut of the second year of life form a wide-row seed crop, after harvest in which the rows are sown alfalfa with low seeding rate and seed before sowing mixed with zeolite clay alanita and of ammonium molybdate in a concentration of 30-40 g/ha

As a predecessor for seeding legumes choose winter wheat or winter barley as they leave in the soil unused trace elements (boron, molybdenum, cobalt, copper, manganese). Trace elements contribute to the increase in the content of chlorophyll in leaves, increased assimilative activity of the whole plant, improvement of the process of photosynthesis. They are on itelna influence the development of seeds and sowing qualities. Under the influence of micronutrients increases the resistance of plants to various diseases and adverse environmental conditions (soil and air drought, excessive moisture, high and low temperatures). For legumes, clover and alfalfa requires a significant amount of trace elements. Therefore, the placement of legume crops after winter cereals can reduce the cost of microfertilizers and increase their forage and seed production.

When laying the seed plot important placement of plants for wide-row active Chelopechene. To reduce the contamination of crops initially seeded with the same culture of clover in a continuous way. This allows you to not only get rid of weeds, and reduce erosion on sloping lands.

The following year, in the phase of budding conduct 1st cut, where to get quality food. After mowing the cultivator implement exhausting crops with row spacing of 60 cm, where podshuveyt alfalfa with a seeding rate of 4 kg/ha. Such a reduced seeding rate provides the best coverage of grass, forming a more generative organs, more active visiting bees-pollinators. In the year of seeding alfalfa to the end of the growing season receive additional food. And the next year (3rd year of life clover) first leguminous crop falls ostaetsya seed alfalfa herbage, which is removed from the 1st cut.

Grass alfalfa developing a strong root system, providing for 6-8 years obtaining forage and seeds with simultaneous improvement of soil fertility due to the ability of legumes to accumulate biological nitrogen.

Due to the fact that plants clover developing safely on slightly acid soils (pH 5-6), and alfalfa - neutral (pH 7-7,5), placing second crop seeds mixed with ceritadewasa clay - alanita, in which is dissolved ammonium molybdate in a concentration of 30-40 g/ha

Alana contains 30-35% of calcium, which reduces the acidity of the soil. Mixing alanita (50-60 kg/ha) of ammonium molybdate (30-40 g/ha) has increased action of ceritadewasa clay in the process of reducing the acidity of the soil solution.

The justification of the selected parameters is due to the action of an applied alanita with calcium, reduces acidity in the seed bed.

Molybdate ammonium mixed with alanita increases the action ceritadewasa clay as prolongator.

Example. On the slopes of 5-6 after harvesting winter wheat soil was treated for sowing clover. Were sown the first culture clover in a continuous way in the amount of 15 kg/ha For the next year clover budding stage bevel on the green mA is su then formed the cultivator wide-row sowing to obtain seeds from the second mowing. After harvesting, the seeds (the first decade of August) in the treated rows were sown alfalfa in the amount of 4 kg/ha

To reduce soil acidity seeds mixed with alanita in the amount of 50-60 kg/ha, saturating him of ammonium molybdate in a concentration of 30-40 g/ha

Alfalfa seeds were removed on the 2nd year of life with the 1st cut when ripe, 70-80% of beans.

This placement crops on sloping lands allows to obtain yields of forage and seeds of both crops from one area to reduce erosion and improve soil fertility.

The method of placing seed grass legume crops on sloping lands, including cartrage placement of two species of plants with different root system, characterized in that the clover sown in a continuous way the predecessor of winter crops and in the second year of life after the first cut to form wide-row seed grass followed after harvesting, seed sowing alfalfa in the aisle with low seeding rate and seed before sowing mixed with zeolite-clay - alanita and molybdenum acid ammonium in the amount of 30-40 g/ha
