What do you need to pay attention to when planting sheep grass? Planting techniques of forage grass

Many sheep farmers will grow their own forage, can be more convenient and effective management of sheep, so what do you need to pay attention to? What are the forage planting techniques? Let's take a look.

First, seed selection according to local conditions.

The normal growth of forage grass is closely related to the suitable climatic conditions and the soil on which to live. Any forage grass has certain requirements for environmental conditions, even if the same kind of forage grass, different varieties have different requirements for environmental conditions. therefore, various places should choose suitable forage varieties according to the local climatic characteristics. In cold areas, cold-tolerant alfalfa, winter rye 70 rye, cross-leaf pine vanilla, Astragalus adsurgens, etc.; drought-tolerant alfalfa, Sudan grass, seed amaranth, etc.; in hot areas, it is appropriate to plant cross-leaf pine vanilla, Sudan grass, bitter cabbage, etc.; in warm and humid areas, ryegrass, Sudan grass, forage corn, bitter cabbage should be planted. Alkaline soil should choose alkaline-tolerant alfalfa, winter rye 70, pine vanilla, Leymus chinensis, etc.; acid-resistant soil should choose acid-resistant pine vanilla, white clover, etc.; barren soil should choose to plant barren-tolerant Astragalus adsurgens, alfalfa, awnless brome, etc.; areas with high soil humidity, it is appropriate to choose white clover, red clover, Elymus, etc.

2. Suitable scale

The scale of raising sheep should be appropriate, and the sheep fields should be matched. General feeding scale should not be too large, every 667 square meters of forage can raise 10 ~ 15 sheep.

III. Scientific set-up

Try to use orchards, woodlands and mulberry fields to plant shade-tolerant forage grass, improve three-dimensional development and utilization, reduce the planting area of the field, or use tidal flat to plant salt-tolerant and high-yield forage grass and develop tidal flat to raise sheep, so as to improve the economic benefit of recommended sheep raising.

Fourth, sow seeds at the right time

As far as possible in the non-high temperature season, select the sunny slope to plant forage crops to avoid the adverse effects of high temperature and low light.

Fifth, collocation planting

To plant forage grass, we should choose forage varieties according to the type and quantity of mutton sheep, according to the principle of combination of length and short, and reasonable supply every year. Reasonable collocation and mixed sowing were carried out according to the growth characteristics of different seasons and different forage varieties to ensure that the total supply of forage grass in each month of the year could meet the needs of livestock and poultry. Ryegrass, red clover and alfalfa can be planted in warm spring, pine vanilla and bitter clover can be planted in hot summer, Dongmu 70 rye can be planted in cold winter, and silage and sun-dried hay can be used as forage supplement. Forage planting can be mixed with Gramineae and Leguminosae. Because the distribution of roots and leaves of these two kinds of forages are different and the nutrients absorbed are also different Gramineae grasses can also make use of the nitrogen provided by legume rhizobium so the forage yield can be significantly increased. In addition, when raising ruminants such as mutton sheep, it is necessary to prevent rumen gas from eating a single leguminous forage. Commonly used forage combinations are: tall fescue plus white clover or alfalfa, awnless brome plus alfalfa, alfalfa plus ryegrass and so on.

VI. Timely harvesting

The yield and quality should be taken into account in determining the harvest time of forage grass for raising sheep. For example, the best harvest time of ryegrass is from heading stage to milk stage, barley is from booting stage, oat is from booting stage to heading stage, pea and black bean are from flowering to podding stage, corn is from milking to wax ripening stage, and alfalfa is flowering stage. When the harvest was too late, the stalks of forage crops aged, the nutrients decreased, and the palatability became worse.
