Abstract

Invention m. used to create pastures in the southern regions. SUMMARY OF THE INVENTION: When creating pastures, grass mixture is sown, containing boreal cereals, legumes and cereals of tropical origin. At the same time, in the spring period, two rows of alfalfa and two lines of tropical grass with the aisles between the lines of the culture of the same species are alternately sown. In the fall, one or two lines of boreal cereal are sown between alfalfa between the rows, and a mixture of boreal cruciferous and leguminous cereals, which are cut in early spring and inter-row spacing, are used for irrigation between the alpine grass.

Description

The invention relates to agriculture and can be used to create pastures in southern areas.

There is a method for creating pastures in continental subtropics by sowing grass mixtures containing alfalfa and timothy grass, alfalfa and hedgehog collectively alternating with lines.

The disadvantage of this method is the low yield of the above-ground pasture mass and low nutritional value and digestibility of fodder due to the imbalance of proteins and carbohydrates, especially in summer.

The purpose of the invention is to increase pasture yields and increase the nutritional value and uptake of fodder, as well as increase the duration of pasture use.

The goal is achieved by the fact that according to the method of creating poly-dominant pastures in continental subtropics, including sowing grass mixtures containing boreal cereals and legumes alternating with lines, the grass mixture additionally contains cereals of tropical origin,

in the spring, two lines of alfalfa and two lines of tropical cereal are sown alternately between the lines of a culture of the same species, one or two lines of boreal cereal are sown between autumn and alfalfa between crops, and a mixture of boreal cruciferous cereals and legumes, which are mown in the early spring period, and between the rows are used for irrigation.

The invention is as follows.

In the spring, blue millet and alfalfa were sown with alternating lines of SO-4,2 in an aggregate with Belarus. At the same time, two lines of alfalfa are placed across the aisles between two lines of tropical grass. In the fall, they sow reed oats between the alfalfa between the fields, and a mixture of boreal cereals, crucifers and legumes, namely a mixture of oats, pike or pelyushki, or Turkestan wickers, which are mown in springtime

As can be seen from the above data, the yield of the forage mass in the dry matter of the grass mixture during all the years of vegetation is higher than the total seed of the individual components of the grass mixture. At the same time, in the year of sowing, the rate of fertilizer in the grass mixture was 50 kr less, and in the rest by 100 kg, compared to pure planting. - The corn crop for two sowing was lower than that of giving birth to grass mixture in the 2nd-4th years of the growing season.

The proposed method of creating grass mixtures involves using only existing agricultural machines and does not require the creation of new ones.

This method of creating pastures ensures a more effective symbiosis of alfalfa: in the early spring the northern grass is better provided with biological nitrogen and the tropical component in the summer. At the same time, pasture yields are increased by 23-41%, the duration of pasture use increases, while reducing the amount of mineral fertilizers introduced into the soil. ,:, Formula a and z.breethen and Method of creating polydominant

In the spring period, two lines of alfalfa and two lines of trophe grass intersected between the lines of one type of crop are alternately sown; in the autumn, one or two seeds of alfalfa are sown between crops in the autumn

the lines of boreal grass, and between the tropical grass between them are a mixture of boron cereals, cruciferous plants and legumes, which they say in the early spring period, are used for irrigation.
