Abstract

FIELD OF THE INVENTION The invention relates to fodder production, in particular, to methods of growing fodder crops. The purpose of the invention is to increase the protein content of the plant mass by creating conditions for the simultaneous growth of leaves. The method of harvesting fodder crops, which includes periodically separating the leaves of leguminous fodder crops at the root of plants, leaving the stems to regrow, increases the protein concentration in the feed and increases its yield per unit area of sowing due to the fact leaf masses remain on the vine to regenerate new leaves on them and re-periodically collect them. On the stems after separation of the leaves, 10-15% of the latter leaves the total leaf mass. A repeated periodic collection of leaves from the stems is done in 20-30 days 4 tab.

FIELD OF THE INVENTION The invention relates to fodder production, in particular, to methods of growing fodder crops.

The purpose of the invention is to increase the protein content in the plant mass by creating conditions for the simultaneous growth of leaves.

According to this method of harvesting legume forage crops, the separation of leaves from the stems is carried out on the root of the plants, the stems with a part of small leaves after the separation of the main mass of leaves remain on the root for regeneration of new leaves on them for re-periodic collection. When the leaves are separated, 10-15% of the total leaves are left on the stalks. Re-periodic collection of leaves from the stems produced in 20-30 days.

The method of harvesting fodder crops provides for the separation of leaves both after the first growth and the subsequent ones, the removal of the leaf mass of fodder crops.

carried out by stripping leaves from stalks on the vine. The stem part of the grass stand is left on the root for multiple re-periodic formation of leaf mass, which comes from the axillary leaf buds along the entire height of the stems and from the sleeping buds, as well as due to the vegetative growth of the remaining leaves on the stems.

Example The removal of leaves at the root was done without cutting the stems and the protein nutritional value of the leaves of different staging was determined. It is established that the most valuable in terms of the protein content are staged young leaves (see Table 1).

PRI mme R 2. Produced combine harvesting of first-cut alfalfa in the budding phase with peeling 85% of the leaves on the vine. At the same time, on the leaves of the plants, the plants in Rusa were of different staging: the upper Russian - staged young leaves, the environment

niy rus - mature leaves, lower rus - staged old leaves.

Peeled stalks with 15% of small leaves were left on the vine to regenerate new leaves on them. Re-stripping of leaves (degree of towing - 85%) was made after 20 days. In this case, the leaves on the plants were one stage of development. In a similar manner, the second, third, and fourth combing of leaves on the vine was made. Herb flour was harvested from leaves harvested by a known method and the proposed method on an AVM-0 unit, 65. Data chemical analysis of feed artificial drying, obtained from the leaves, harvested by two of the above methods, provided in table 2.

Example Repeated separation of the leaves was carried out and conditions were created for the simultaneous growth of the leaves throughout the habit of the shrub, while the organic matter of the leaves contained more protein. Subsequent crop removal was repeated after 20-30 days during the period of maximum protein concentration.

PRI me R 4. Separate whether the leaves of alfalfa from the stalks at the root, leaving the stems x 15% of the leaves. After 5, 10, 15, 20 and 25 days after collecting the leaves, the weight gain of the leaves, the content of the protein in them and the yield of the protein from 1 g (cm / ab. H) were determined.

EXAMPLE 5. Alfalfa leaves were separated at the plant root, leaving 5, 10, 15 and 20% leaves on the stalks. 20 days after separation, the protein content in the leaves and the protein yield from 1 hectare were determined (see Table 4).

40 Protein content in leaves of different ages.

Thus, the proposed method of growing leguminous forage crops allows for an increase in the protein concentration in the leaves to be smoothed due to the simultaneous growth of staged young leaves along the entire stem. Re-growth of leaves after their separation occurs from the axillary buds of the leaves, from dormant buds throughout the height of the stalks remaining on the root,

as well as by intensive growth of 10-15% of the small leaves left on the stalks after the previous separation.

In addition, leaving the stems on the vine after the leaves are separated allows

reduce the length of the growth period of new young leaves by 10–20 days compared with the method in which the whole plant has to be mowed, and also significantly increase the proportion of leaf weight per hectare of sowing leguminous forage crops during one growing season. In this case, depending on the weather conditions, there is a real opportunity to carry out 5-6 leaves for the growing season of the plants.

Claims (1)

The invention of the method of harvesting fodder crops, including reusable leaf separation at the root, characterized in that, in order to increase the protein content in the plant mass by creating conditions for the simultaneous growth of leaves, their separation is carried out by periodic stripping every 20-30 days, with 85-90% of their mass separated in each cycle.
