Green Storage Technology of Corn Stalk

The corn straw green storage technology is to preserve the unaged corn straw through special treatment technology, so that it can be used as livestock feed in autumn and winter, and the quality and nutrients of the feed can be preserved almost as well. so that livestock in winter can also enjoy the green of summer, autumn grass fragrance, this technology is specifically applied to Gramineae and legumes.

Harvesting technology

When preparing corn silage in agricultural areas of our country, the technology of harvesting corn is mainly harvested by stages, that is, after the corn plant is cut down manually, it is transported to the silage facility by animal power or other transport machinery, and then manually transported to the hay guillotine. After processing and chopping, it is loaded into silage facilities for silage. The main feature of this harvesting process is that the whole operation is completed in several stages, mainly manual operation, high labor intensity, low production efficiency, and the silage process generally takes 3-5 days. On the other hand, the combined harvesting process uses a special green fodder harvester to complete the cutting, transportation, shredding of corn plants and loading the chopped materials into feed trailers in the field at one time. The trailer loads the feed into the silage facility and completes the whole process of corn silage after compaction and sealing.

Raw material harvesting

In order to take into account the feed quality and nutritional composition, it is best to mix forage grasses with high sugar content and protein-rich legume grasses that are not easy to silage. The proportion of silage is 2:1 or 1:1 for Gramineae and Leguminosae.

Clean up preparation

According to the size of the silage, select the appropriate silage equipment, and clean it before use, remove the dirty soil, remaining raw materials, etc., and repair the place where the soil falls off.

Determine water replenishment

The moisture content of silage raw materials is 65%, and the insufficient part needs to be added to the quantity. For example, corn stalks with 40% water content need to be watered (in terms of 1 ton) during silage, 1000 × 65% muri 1000 × 40% corn stalks 250 kg, and so on. If the moisture content of newly harvested grass (straw) exceeds 70%, it should be dried slightly or hay powder with less water content should be added to reduce its moisture content to about 65%.

Raw material treatment

Before silage, the raw materials should be crushed and cut short for three purposes, one of which is to facilitate compaction and clean the air in the middle of the material. The second is to increase the contact area between inoculants and materials, which is conducive to the rapid reproduction of bacteria. The third is to make the juice in the raw material fully seep out and wet the surface of the raw material, which is beneficial to the rapid growth of microorganisms in the starter and improve the quality of silage. The degree of shredding of raw materials should be determined according to the type of livestock fed and the quality of the raw materials. Generally speaking, the green raw materials with high water content can be cut longer, the forage fed to large livestock can be cut longer, and the harder raw materials with low water content can be cut finer, or beat into fine powder. Generally, the length of storage material cut is 2-5 cm. For the silage of raising cattle and sheep, the straw kneading grinder produced by Shaanxi Chenshuo Environmental Protection Agriculture Co., Ltd. has a better effect.

Raw material filling

The filling principle of silage is to be quick. The silo should be filled on the same day. Seal the cellar on the same day to avoid the deterioration of the silage before filling the seal, and even the large-scale silage should be finished within 2 days. At present, many farmers have generally set up large ponds, which can not be filled with sealed ponds on the same day, or even exposed to the air for a few days, so that spoilage bacteria can quickly decompose the nutrients in the raw materials under aerobic conditions, so as to make the raw materials mildew and deteriorate and reduce the quality of silage. second, compaction. The silage is compacted as much as possible, and the large cellar is compacted mechanically. Where it can't be pressed, it should be stepped on manually. Silage in plastic bags should avoid damage to plastic bags.

Container seal

Silage should be sealed immediately after filling, small bagged silage can be tightly sealed with rope, sand tank and other small container silage can be tightly sealed with plastic film, no air leakage can be done, large silage cellar silage is covered with plastic film and sealed with a layer of Reed mat, straw mat, etc., and then covered with soil cover.
