Scientific green storage method

Qingcun feed has the reputation of “canned grass”, succulent, odor, acid digestibility, high digestibility, and nutrient-rich. It is the best feed for livestock such as cattle and sheep. Green storage method is simple, low cost, as long as in a short period of time to send back the green storage materials, master the appropriate water, smashing and pressing, sealing and sealing, do not invest a lot can be successful. Therefore, when harvesting raw materials, it is necessary to transport green storage materials at the fastest speed.

The timely harvest time of corn stalk should be harvested 7 days to 10 days before the grain is sufficiently ripened, and timely harvest the stalks, the yield and quality of the grain are almost unaffected, and the nutritional value of the straw is greatly improved. If the harvest is too late, the green storage pit is difficult to compact, the fermentation quality is poor, the storage period is short, and the digestibility of various nutrients is poor. The harvest of pods is generally suitable for flowering of 10% of the plants.

Preparation before harvest 1. Clean the green storage pit. Clean up residual straw and impurities from the green storage pit. 2. Clean up the area around the green storage pit. Place the rake machinery in a suitable location and prepare the compaction tools to prevent the mud from flowing into the green cellar. 3. Do not face the green storage pit facing west or south. The length of the green storage corn stub is generally about 33 mm. If it is too short, it will lead to reduction of effective fibers that stimulate chewing and ruminal acidosis. If it is too long, it will affect the compaction density of the pits, resulting in a decline in the quality of the silage.

The management of the Green Storage Pit shall determine the size of the green storage pit based on the speed of the fish farm (at least 15 centimeters per day). In the filling of the blue stock material, it is fast and tightly packed (every 15 cm to 20 cm thick, it is compacted with a compaction tool). Xiaoqing's storage pit is better than Daqing's storage pits. It can quickly fill and seal, and it can be fermented faster and better. It is easy to manage with small material intake surface and low loss of dry matter.

The use of additives to improve the storage of fermented microbial inoculants The principle of the inoculant is to control the fermentation by adding fast-growing pure lactic acid bacteria to produce high-quality silage. Lactic acid bacteria are added in a certain proportion in the green reserve feed. Enzyme additives use enzymes that degrade plant fibers. The advantage is that these enzymes can digest part of the plant cell walls and produce soluble sugars. Lactic acid bacteria use these sugars to ferment, thereby lowering the pH of the blue stocks, promoting the fermentation of blue stocks, improving the quality of fermentation, and reducing the loss of dry matter; it helps to improve the digestion of animals. Rate and utilization of green storage. Fermentation inhibitor Propionic acid has the strongest ability to inhibit fungal activity, it can effectively inhibit the production of harmful bacteria (such as aerobic deterioration of yeast and mold). The nutrient additive urea has been added to the green storage corn as a cheap source of crude protein.

Management after opening the cellar l. Take out enough of the green reservoir every day. 2. Keep the receiving surface clean and reduce losses. 3. After the materials are finished, they should be quickly sealed to reduce air retention and prevent aerobic deterioration. In short, good management during harvesting and storage will greatly help maintain the quality of blue storage from the field to storage.
