1, grazing utilization
Caragana korshinskii is a high-quality leguminous forage. Caragana is an excellent forage shrub for livestock, with lush foliage, high grass yield, rich nutrition and strong palatability. Large area of Caragana korshinskii can increase forage yield and greatly improve the diet quality of livestock. Caragana grassland can be grazed all year round, especially in winter and spring and dry years, and its feeding value can be improved. When the grass withers or the land is sealed by snow in winter, livestock can eat the twigs and dead leaves of Caragana korshinskii without weakening, which is beneficial to pregnant lambs; When the early spring grass is green and yellow, it leaves early and blooms early. When the mother animals eat its branches, leaves and flowers, it can quickly recover and ensure lambing. In summer drought, the shallow-rooted grass on the grassland withered, and some even died. Caragana korshinskii can still grow well with its strong root system and drought resistance, and it has become a "life-saving grass" for livestock in summer drought. ?
2, grass powder or grass particles processing
The coarse and old branches of Caragana korshinskii are crushed and processed into grass powder or grass particles, which are supplemented to sheep and goats in winter and early spring, and the palatability is also very good. At present, the use of Caragana in our flag is limited to cattle and sheep, and the utilization rate is less than 1%, which makes a large number of Caragana branches aging or even dying, resulting in waste of resources. Through manual or mechanical mowing, the branches of Caragana korshinskii are crushed and processed into grass powder or grass particles, which can be fed to livestock in winter and early spring, which can effectively develop and utilize Caragana korshinskii resources, provide high-quality protein feed for animal husbandry production, and achieve remarkable economic benefits. ?
3. Silage utilization
Caragana silage is one of the best utilization methods. The best utilization period of silage is flowering period and nutrition period. The results showed that Caragana korshinskii was crushed at flowering stage, with green color, slightly sour smell and clear structure. The PH value was 4.6, crude protein 14.59%, crude fat 3.38%, crude fiber 34.4 1% and crude ash 8.58%. It can be fed, and too long pit opening time will reduce the dominant position of lactic acid bacteria. Therefore, according to the storage capacity, the amount should not be too large, and its utilization time can be extended at low temperature. It can also be bagged or cellared with multi-strain solid starter. ?
The corn stalk and Caragana korshinskii were crushed according to the ratio of 2: 1, and then mixed evenly. After 30 days' storage, the mixed liquor is blue-green, slightly acidic in smell and clear in structure, with PH value of 3. 1, crude protein 10.02%, crude fat 3.34%, crude fiber 34.05% and crude ash 5. Therefore, the mixed storage of Caragana korshinskii and corn can improve the palatability of Caragana korshinskii. ?
4. Other uses
Caragana has strong adaptability, drought resistance and barren resistance, and is not afraid of sand pressure. It has good functions of wind prevention and sand fixation, soil and water conservation and improvement of ecological environment. Caragana korshinskii is a leguminous plant with well-developed root system and contains a lot of nitrogen and minerals. Root system has many nodules, which can fix nitrogen in the air, increase soil organic matter and improve soil fertility and structure. Caragana branches and leaves are rich in nitrogen, phosphorus, potassium and other elements, and are excellent green manure. In addition, it is a good nectar source plant. The pods and seeds of Caragana are also good feed. According to the analysis, its seeds contain 27.4% crude protein and 3 1.6% starch. The fattening effect of processed seeds on sheep is no less than that of soybeans. The roots, flowers and seeds of Caragana can be used as medicine, which has the effects of nourishing yin and blood, dredging meridians, calming the heart and relieving itching.
