Example Embodiment

[0019]Example 1: Making urea into pulverized powder; in the field, place the powder sprayer at the feed inlet of the pick-up pulverizer, and spray the urea powder into the green corn stalks with a moisture content of 15% to be wrapped. The bundling is carried out, wherein the spraying amount of the urea powder is 4% of the dry weight of the corn stalks. After the baling, the feed is obtained after 15 days of natural ammoniating.

[0020]In the method of Example 1, urea is added uniformly, and no water is used for treatment, which is convenient. The feed obtained by unpacking observation has significant ammoniating effect and no mildew. Compared with the green corn stover without ammoniating treatment, the crude protein increased by 12%. After feeding cattle, feed intake increased by 15% and digestibility increased by 13%.

Example Embodiment

[0021]Example 2: Making urea into pulverized powder; in the field, using a hand-held duster, spray urea powder into the rice straw with a moisture content of 13% to be wrapped for storage in the pit, where the urea powder is applied The spraying amount is 5% of the dry weight of the rice straw. After baling, it is naturally ammoniated for 13 days to obtain feed.

[0022]In the method of Example 2, urea is added uniformly without water, and the operation is convenient. The obtained feed has a significant ammoniated effect and no mildew. Compared with rice straw without ammoniated treatment, crude protein increased by 11%. Feeding sheep with open packages increased the feed intake by 12% and the digestibility by 10%.

Example Embodiment

[0023]Example 3: Dissolve urea in water according to the urea mass percentage concentration of 35% to obtain a urea solution; in the field, use a sprayer to spray the urea solution into the air-dried corn stover to be wrapped. The application amount is based on the urea mass in the urea solution accounting for 4% of the air-dried weight of the straw, and then the bale is carried out, and the feed is obtained after 10 days of natural ammoniating.

[0024]In the method of Example 3, the urea is added uniformly, the water consumption is small, and the operation is convenient. The feed obtained by unpacking observation shows significant ammoniating effect and no mildew. Compared with the air-dried corn stover without ammoniating treatment, after feeding cattle, crude protein increased by 10%, feed intake increased by 12%, and digestibility increased by 9%.

Abstract

The invention discloses a method for preparing feed through water-saving homogenized ammoniation of crop straw, and relates to a preparation method of crop straw feed. The invention aims to solve thetechnical problems of high cost and incomplete ammoniation of an existing method for straw ammoniation through urea. The method comprises the following steps: crushing urea into powder, spraying ureapowder into straw by using a powder sprayer, and then carrying out baling or cellar storage ammoniation; or dissolving urea into a small amount of water, spraying the urea solution into the straw by using a sprayer, and then carrying out baling or cellar storage ammoniation. Compared with untreated straw, the straw treated has the crude protein increased by 9%-12%, the food consumption increased by 12%-15% and the digestibility increased by 8%-13%, is not limited by sites and moisture conditions, and can be applied to the field of large-scale improvement of straw as feeds.

Description

technical field [0001] The invention relates to a preparation method of crop straw feed. Background technique [0002] As the environmental problems caused by straw burning in the field have gradually been paid attention to, extensive research has been carried out on the utilization of straw "five materials". It is considered to be the most effective way to treat and improve straw as feed for ruminants; with the popularization and application of large-scale harvesting and crushing machinery, large-scale processing of straw as feed is becoming more and more possible and has gradually attracted attention. [0003] China produces 800-900 million tons of corn, rice, wheat and other crop straws every year. The emergy content of these crop straws is the same as forage grass such as chinensis, and has great value as feed for ruminants such as cattle and sheep. However, due to the low digestibility of various crop straws, it is theoretically very feasible to use urea to ammoniate ...
