Qingcao feed has the reputation of “canned grassâ€, juicy and palatable, with a fragrant smell, high digestibility and rich nutrition. It is a superior feed for livestock such as cattle and sheep. The green storage method is simple and low in cost. As long as the green storage material is shipped back in a short time, the water is suitable, the smashing is pressed, the pressure is sealed, and the investment can be successful without a large investment. Therefore, when harvesting raw materials, it is necessary to transport the raw materials at the fastest speed.
Timely harvesting period Corn stalks should be harvested from 7 days to 10 days before the seeds are fully matured, and the straws are harvested in time. The grain yield quality is almost unaffected, and the nutritional value of the straw is greatly improved. When the harvest is too late, it is difficult to compact the green storage, the fermentation quality is poor, the storage period is short, and the digestibility of various nutrients is poor. The harvest of alfalfa is generally suitable for flowering of 10% of the plants.
Preparation before harvest 1. Clean up the green storage. Remove residual straw and impurities from the clam. 2. Clean up the area around the green storage. Place the weeding machinery in a suitable location and prepare the compacted tools to prevent muddy water from flowing into the green storage. 3. The direction of the Qing dynasty should not face west or south. The length of the green corn stalk is generally about 33 mm. If it is too short or too thin, it will lead to a reduction in the effective fiber for stimulating cattle chewing, and rumen acidosis will occur; too long and too thick will affect the compaction density of the cockroach, which will cause the quality of the green storage to decline or deteriorate.
The management of the Qingpu dam should be based on the picking speed of the farmer's household to determine the size of the shoal. When filling the silage material, it can be loaded quickly and compacted. Xiaoqing Chuan is better than Daqing Chuan, it can quickly fill the seal, can fertilize faster and better, the feeding surface is small and easy to manage, and the dry matter loss is small.
The principle of fermenting microbial inoculants using additives to improve silage is to control the fermentation by adding fast-growing pure lactic acid fermenting bacteria to produce high quality silage. Lactic acid bacteria are added in a certain proportion in the green storage feed. The enzyme additive uses an enzyme that degrades plant fibers. The advantage is that these enzymes can digest part of the plant cell wall and produce soluble sugar. The lactic acid bacteria use these sugars to ferment, thereby reducing the pH value of the green storage, promoting the green storage fermentation, improving the fermentation quality and reducing the dry matter loss; helping to improve the digestion of the animal. Rate and utilization of green storage feed. The fermentation inhibitory propionic acid has the strongest ability to inhibit fungal activity, and it can effectively inhibit the production of harmful bacteria. The nutrient additive urea has been added to green storage corn as a source of inexpensive crude protein.
Management after reclamation l. Take out enough green stocks every day. 2. Keep the take-up surface clean and reduce losses. 3. After the material is finished, it should be quickly sealed to reduce air retention and prevent aerobic deterioration. In summary, good management during harvesting and storage can be of great help in maintaining the quality of the green storage from the field to storage.
