The harvest was too early. Although the crude protein content of pasture was high, the water content was also high, the hay yield was low, and the modulation was difficult and economically uneconomical. At the same time, the grassland regeneration performance will also be weakened, grasses will rot and the wintering rate will be low. When harvesting is too late, the quality and palatability of hay are reduced. So when does the grass work? This depends on the local rain conditions. There was plenty of rain, grass was short, and some grass could be dragged afterwards. According to our experience: First, look at solar terms. As the saying goes: "The grass in the sky, the treasure in the trough." It refers to the day of the day playing grass, down to the end. At this time, generally 1 kg of grass can top 2 kg of autumn grass or 3 kg of frosty yellow grass. Two to see the color. When the grasses are mature, they turn from dark green to light green, and a layer of white ash hangs on the blades of grass to prove that pasture has been harvested. The third is to hand rub a handful of grass, if the grass is cut off, indicating that the grass is tender, if 50% to 60% have not been cut off, it shows that the grass has been a little old. In the northeast region, the harvest period of pasture is generally from the end of July to the end of August. At this time, the pasturage has a comprehensive nutrition and a high value, which will neither damage the grassland nor facilitate the regeneration of pasture. When harvesting pasture, leave it to be appropriate. The length of the grasshopper depends on the specific circumstances. Generally, the grass stays 5 cm to 8 cm, and the autumn grass is left longer for a safe winter. In addition, weeding grass is in the rainy season and the grass has high water content. Modulation of hay must be meticulous and scientific to prevent moldy rot. The meaning and principle of hay modulation How to store the forage feed that is harvested is another important link in forage production. Before storing hay, it must be modulated. Drying is an important step in preparing hay. The proper treatment of the drying process directly affects the quality of the stored hay. Generally, the moisture content of the hay is 13%~18%. Hay has high nutritional value and is an important source of phosphorus, calcium, vitamins and trace elements in herbivores. At the same time, it is also an important balanced feed. As hay is easy to store and easy to transport, it is an important material basis for the development of animal husbandry production. Technical points of hay modulation 1. The drying time is as short as possible. Because forage grasses produce a series of complicated physical and chemical changes during the drying process. Due to energy consumption, loss of vitamins and many other reasons, the biological value of hay is often reduced. Therefore, try to shorten the drying time as much as possible. 2. Forage collection and transportation. It should be carried out as far as possible when the delicate part of the pasture has not yet been broken and is not easily broken. 3. For the withered pastures, we should try to prevent raindrops from getting wet and avoid prolonged sun exposure. Hay modulation method There are many ways to modulate hay. The most common application at present is the natural drying method. Natural drying is generally divided into two phases. The first stage: In order to quickly kill the grazing grass cells and reduce the loss of nutrients, the “ground floor tiling method†should be adopted. Exposure for 4 hours to 5 hours allows water to evaporate quickly. The advantage is that no extra energy is needed, the cost is low, the modulation method is simple, and it facilitates mass production. If properly prepared, higher quality hay can be obtained. The specific method is to select sunny and high-temperature weather. After the pasture is cut down, it is first spread on the grass by 3 cm to 5 cm in thickness, exposed to sunlight for 4 hours to 5 hours before the leaves begin to fall off (water content is about 35%~ 40%), the grass is piled into small piles (30 kg to 50 kg) with wolfberry; the hay can be conditioned into hay in the heap for 1 to 2 days (water content is about 15% to 48%). The second stage: to speed up the sun, so that enzyme activities as soon as possible to stop; to try to reduce the loss of vitamins and carotene caused by sun exposure, it is appropriate to use a small heap or small hoe drying system to make it gradually dry. The size of the heap is about 1 meter high and about 1.5 centimeters in diameter. When the moisture content drops to 15%~18%, it can be stored on the top of the palate. The moisture content of hay in a humid area (such as beach) should not exceed 10%. In recent years, electricity and solar energy have been widely used in agricultural production, and advanced pasture extrusion drying, microwave drying and solar ventilation drying techniques and methods have gradually been applied in animal husbandry production. Which is more suitable for all parts of China is a plastic greenhouse solar drying method. The plastic greenhouse solar drying method is to put dry grass in a plastic shed, and blow dry air heated by solar energy so as to achieve the purpose of drying pasture. How to store grass After the pasture has been dried and conditioned, when the humidity reaches about 15% (any hand-picked hay, shaking or shaking in the hands, there is a crisp rustle, and the rolling in the hands will not break), and can be stored into a large clam. The sites should be located in a location with high altitude, dryness, no water accumulation, and close to the livestock house. It's best to have walls or clips around. This can prevent wind and prevent the scourge of scattered animals. At the same time, it should also be separated from various buildings by a certain distance, especially not close to high-voltage lines to prevent electric shocks and fire. Drainage trenches should be dug around grasshoppers to reduce wind and rain erosion. It is best to put a layer of wood or branches on the bottom of the floor to prevent the bottom of the loquat from being affected by moisture. Identification method of hay quality: under normal conditions, green grass of Gramineae is green; sedge grass is green and glossy; leguminous grass is greener than fresh, and it is not defoliated, its smell is fragrant, and it is not musty, and handkerchief is more flexible. . If the color is abnormal, it means that there is too much sun or mildew in the rain. Such hay should not be fed. Supply Ningxia Pure Biotechnology Chinese Herbs and Plant, or the health foods,Anyway, at least commonly used species will be added to this herbal list constantly, such as Ren Sheng (Ginseng), Dang Gui (Dong Quai), Gan Cao (Licorice), Huang Qi (Astragalus), Ma Huang (Ephedra), Chai Hu (Bupleurum), Di Huang (Rehmannia), Sheng Jiang (Ginger), and Gou Qi Zi (Chinese Wolfberry), etc. Our future planning is to pack as much detail as possible for each herb and formula, covering such as source, features, indications, clinical applications, usage and dosage, cautions, historical documents, and references, etc. Finally, it would be highly appreciated if you can take some time off and feedback us, if any.
