RU1817965C - Method of growing alfalfa for seeds - Google Patents

Description

The invention relates to agriculture, and in particular, to methods for producing seeds of perennial leguminous herbs.

The aim of the invention is to increase seed yield by improving the illumination of plants, creating good; under favorable conditions for the growth and development of the generative organs of alfalfa during its cultivation, as well as the creation of (enlarged) buds and inflorescences on the entire surface of the crown of plants. - / ....:. ;;; i

This goal is achieved when the sowing is carried out in a wide-spaced manner with a distance of 70 cm, which allows to increase the feeding area, lighting, method-:. promotes better development of the root system and greater formation of generative Organs. In the process of caring for crops, check; d shallow slitting (up to 15 cm) across the crops, at the beginning of budding-; - cultivation of plants with soil faces with a height of 5 .... 8 cm and in the budding phase (especially for the second and subsequent years of alfalfa life), along with common technology, plants are mowed at a height of 25 ... 30 cm from the soil surface, as shown in the drawing. G

The biological feature of alfalfa, as a perennial culture, is the uneven growth and growth, and thus the mass of grass throughout the field in rows and bushes turns out to be uneven. Especially, if a large amount of precipitation falls in the spring, then alfalfa grows very much, lodges and creates natural conditions for the plants to shade one another. At the same time, the number of inflorescences and flowers in them, their uneven production and, subsequently, different ripening periods of beans, are reduced, which significantly reduces the yield of alfalfa seeds.

I The negative effect of shading affects the root system - the outflow of plastic substances from the terrestrial parts of plants is reduced. The intensive growth of the alfalfa vegetative mass can be controlled by mowing and hilling the grass, not lowering, but increasing the seed productivity of crops due to the formation of uniform grass and the formation of inflorescences over the entire surface of the bushes.

Based on long-term observations, you have revealed the advantages of the proposed method compared to previously known ones. The method protects against overgrowth of the leafy mass and all plants fall under the same conditions, the remaining part of the leafy mass contributes to the intensity of photosynthesis and the formation of generative organs. Due to the decrease in the duration of other phenological phases, the phase of mass bean drilling occurs 15 ... 20 days earlier. In addition, the method of mowing and hilling allows you to partially get rid of soybean. pests and methods, it is more effective mechanical pollination and pollination by insects.

SUMMARY OF THE INVENTION A method for growing alfalfa on seeds, including sowing seeds, caring for plants, shortening the main stems during budding. characterized in that, in order to increase the yield of seeds by improving the light-air regime and the formation of generative organs over the entire surface of the stalk, the sowing is carried out in a wide-row way, the plants are taken care of by saping across the sowing and hilling the plants with a soil roller 5 high -8 cm at the beginning of the budding phase, and the shortening of the main stems into the budding phase is carried out on. 25-30 cm from the surface of the soil.
