Qinghai Tibet fodder breed, the main livestock breed in Qinghai Tibet

You're talking about silage.

Commonly used silage raw materials for grasses include corn, ryegrass, and sagebrush; legumes include alfalfa, clover, milk vetch; Other rhizomes and leaves include sweet potato, pumpkin, amaranth, aquatic plants, etc. In order to ensure the quality of silage, the following matters should be paid attention to in the selection of silage raw materials.

1. The sugar content of silage raw materials should be high. Sugar content refers to the content of soluble carbohydrates in silage raw materials, which is the basic condition to ensure the mass reproduction of lactic acid bacteria and the formation of sufficient lactic acid. The sugar content in silage raw materials should be at least 1% of fresh weight.

Raw materials with higher carbohydrate content and less protein content in plants should be selected as raw materials for silage. For example, grasses, sunflower stems and leaves, and root tubers are all species with high carbohydrate content.

The raw materials containing less soluble carbohydrates and more protein, such as legumes and potato stems and leaves, are difficult to silage successfully, and are generally not suitable for single storage.

2. Silage raw materials must contain appropriate moisture. Proper hydration is an important condition for the normal activity of microorganisms. The moisture is too low, which affects the activity of microorganisms, and is also difficult to compact, resulting in a large number of aerobic bacteria and making the feed moldy and rotten; Too much water, low sugar concentration, conducive to the activity of butyric acid bacteria, easy to agglomerate, silage quality deteriorates, at the same time, plant cell juice loss, nutrient loss is large.

For feed with too much moisture, it should be slightly dried or mixed with dry feed silage. When the moisture content of silage raw materials reaches 65-75%, it is most suitable for lactic acid bacteria to reproduce. The water content of leguminous forage grass should be 60-70%. The moisture content of coarse and hard raw materials is 78-80%; The water content of tender, juicy and soft raw materials should be 60%.

The main livestock breeds in Qinghai-Tibet are yaks, Tibetan sheep, Tibetan goats, etc.

The Qinghai-Tibet region is one of the five major pastoral areas in China, where the sunshine is strong, the temperature difference between day and night is large, so the grassland is widely distributed, and the nutrient content of forage is high. The altitude of the place is high and there is a lack of oxygen, so the main livestock species are yaks, Tibetan sheep, and Zang goats, and the grazing is mainly self-sufficient nomadic herding. Among them, the yak is a representative breed of livestock in Qinghai-Tibet, its hair is thick and long, cold hardy, short and healthy, good at climbing mountains and carrying weights, and is known as the "boat of the plateau". <

The main body of the Qinghai-Tibet region is the Qinghai-Tibet Plateau, which is known as the "roof of the world" This region is the source of many major rivers in Asia, and the Yangtze River, the Yellow River, and the Lancang River all originate here This region has a large number of rare animals, such as Tibetan antelopes, snow leopards, wild asses, etc. It is of great significance to protect the natural environment of this region and prevent and control ecological damage and grassland degradation

Types of cultivated land in Qinghai-Tibet.

1. Paddy fields. The type of cultivated land includes paddy field, paddy field refers to the cultivated land with field roots, can store water, is used to plant lotus root, mat grass, rice and other aquatic crops, and paddy field can be changed to plant early crops because the environment is too dry and early to store water.

2. Dry land. Dryland refers to cultivated land that has no irrigation facilities and relies on natural precipitation to grow dryland crops, and when using dryland to grow crops, it is necessary to apply enough base fertilizer to it, and you can choose well-rotted organic fertilizer or compound hidden rock Hefei.

3. Vegetable patch. When planting vegetables, you need to plough 30 cm of vegetable land to make it more soft and breathable, which is conducive to the vigorous growth of vegetables.

4. Water the ground.

Watered land refers to the field with sufficient water source and irrigation equipment in addition to paddy fields and vegetable fields, and when using watered land to plant crops, it is necessary to water according to the weather conditions and keep the soil slightly moist to avoid root rot.

5. Wangtiantian.

Potassium permanganate and herbicides are sprayed into the soil to promote the healthy growth of plants.

Qinghai-Tibet region is an important pastoral area in the country, the main livestock are yak, Tibetan sheep, Tibetan goats, etc
