What is the difference between green storage corn and conventional corn?

Silage corn. What are the differences between varieties and common corn varieties, and the plant types are different. Silage corn products are grown in tall plants, generally in meters, up to 4 meters in height, to produce fresh straw, while common corn produces corn kernels.

<> harvest time is different. The harvest period of silage corn is from the end of milk maturity to the beginning of wax maturity, and the milk line reaches 1 2 3 4 (or 1 2 milk stage to 1 4 milk stage) of the grain. At this time, the same is true for biological yield and nutritional value.

However, regular corn can only be harvested after the ripening period, when the milk line has completely disappeared and black layers have appeared.

Different uses. Silage corn is mainly used for feed, and common corn is not only used for feed, but also as an important food and industrial raw material. Corn silage.

The feed is nutritious and also rich in carbohydrates.

Vitamins and minerals. Cows fed corn silage produce 500 kg of fresh milk per year and save about a fifth of their concentrate feed. Doing a good job of corn silage can greatly improve the balance of green forage**.

The stems, leaves, fruits, and ears of silage corn can be used to make silage, and the nutrient loss of corn straw can reach 20% 30%, or even more than 40% after drying, while the nutrient loss after silage corn is only 5% 10%, especially can effectively preserve vitamins. The color is still green, sweet and sour wine aroma, tender and juicy, good palatability, and the digestibility can be increased by 20%.

The plant types were different, the tall plants of silage corn products were mainly used to produce fresh straw, and the common corn was mainly planted with corn grains. The harvest period of silage corn is from the end of milk maturity of the grain to the wax maturity stage, and the normal corn must be after the maturity period.

Green storage corn refers to the corn is not yet mature, and it is stored together with the corn stalk to become four ingredients, while conventional corn refers to the normal maturity of corn and storage in the form of corn kernels.

Different heights, different colors, different harvesting times, different uses, and different economic benefits.

The specific differences are as follows:

1.Silage corn.

Corn is a family of grasses.

An annual high-yielding crop, silage corn (also known as forage corn) does not refer to a variety of corn, but because of its use, silage corn is the storage of fresh corn in a silage cellar (i.e., silage) and fermentation to make feed or industrial raw materials. Silage corn is a general term for a class of corn for a class of purposes in view of agricultural production habits. Silage corn is different from regular seed corn.

2.Green storage corn :

Green storage corn is the fresh corn cob.

Together with the fresh corn stalks, they are crushed and packed into a bundle through the green storage fermentation machinery, which can be stored for 1-3 years!

Silage corn advantages:

1.Higher yields can be obtained by selecting specialized maize varieties [2]. There are also some planting units that harvest common seed corn for silage in advance, but often have lower yields.

Generally, under the condition of moderate fertility, the yield of fresh straw per mu of special silage corn varieties can reach tons. However, there are only tons of ordinary seed practical corn. Planting 2 3 acres of silage corn can solve the annual green roughage ** of a high-yielding dairy cow.

2.Corn silage.

The material is rich in nutrition, aromatic smell, high digestibility, and the crude protein content in the fresh sample can reach more than 3%, and it is also rich in sugar. Feeding dairy cows with corn silage can increase the production of fresh milk by more than 500kg per cow a year, and can also save 1 5 concentrate feed.

3.Silage corn production occupies a small space, and can be stored for a long time, can be balanced throughout the year**, is the most effective way to solve the needs of cattle, sheep, deer, etc.

Advantages and methods of green storage corn:

1.The corn straw that remains green or partially green after the autumn harvest is preserved for a long time by silage method, which can preserve its nutrients well, and the texture becomes soft, has a fragrance, can enhance the appetite of cattle and sheep, and solve the shortage of forage in winter and spring.

2.At the same time, the production of silage saves half of the floor space compared with stacking the same amount of hay, and is also conducive to fire prevention, rain prevention, mildew prevention and the elimination of crop pests on the straw. The key to the technology of silage production is lactic acid bacteria.

provides the necessary conditions for reproduction.

First, in the process of modulation, the raw materials should be as short as possible, and they should be compacted tightly when loading the cellar to remove the air in the cellar as much as possible.

3.The second is the water content in the raw materials.

At about 75% (i.e., when you can wring out the water by hand and cannot drip it), it is most suitable for the reproduction of lactic acid bacteria. When silage, it should be decided whether it needs to be sprinkled according to the greenness of the corn stover. Third, the raw materials should contain a certain amount of sugar, and the sugar content of general corn straw meets the requirements.

There are many methods of silage corn stalks, and only the most basic general silage method is introduced here, which is convenient for the popularization and promotion of the vast number of rural areas.

Our country since the eighth of the last century.

Since the 90s, 168 silage corn products have been approved

species, including 30 varieties in China and 138 varieties in the province.

After years of observation, the varieties that sell well in the market and have a good reputation include Yu Silage 23, Dajingjiu 26, Beinong 208, Jingke Silage 516 and so on.

It is understood that the Yu silage 23 and Dajingjiu 26 of the Dajingjiu industry are still good. After inquiry, the Ministry of Agriculture of the People's Republic of China in 2016 listed Yu silage as the leading variety of silage corn, and Dajingjiu 26 was listed as the control variety of the national silage corn regional test in North East China.

Silage corn retains the nutrients of corn stalks as feed to the greatest extent, the silage process is the ammonia process and lactic acid fermentation process, silage corn is the feed that cattle and sheep livestock like to eat, the storage time is long, and it can be fed all year round. The harvest time of silage corn and ordinary corn is different, so when choosing seeds, it is necessary to take into account the problem of growth period, and it is recommended to choose varieties with a longer growth period, which ripen about a week later than ordinary corn, and the purpose is not to harvest late, because it is necessary to ensure the greenness of the leaves, as well as the yield and quality.

When choosing, be sure to choose silage corn that is suitable for local cultivation, so as to ensure the stability of the yield. Ask your local agriculture department, who generally have years of experience in growing corn and know which corn is suitable for growing locally and which corn can be used as silage. Longyu 15 green storage corn varieties, suitable for the whole year activity accumulated temperature greater than 10 degrees to 2400 degrees can be planted, Longyu 15 from the green storage yield and quality are given priority to the recognition of growers and breeders, the general corn stalk palatability is poor, cattle and sheep are not delicious.

Silage corn stover is high in sugar, protein, and organic matter than ordinary corn seeds. The palatability is very good. Cattle and sheep love to eat.

In one, the purchaser tests all the contents. So don't dare to be ambiguous. A year of hard work has been in vain.

Silage corn has different cultivars of silage corn in different regions, and the selection of planting varieties can be consulted in detail with the extension center of the local Animal Husbandry and Veterinary Bureau. Special silage corn varieties are required to reach the wax maturity period at the time of mowing, and the varieties must first be combined with the climatic conditions of the planting place to select suitable early-maturing or late-maturing varieties; Varieties should also be combined with environmental conditions and cultivation techniques to achieve high yields and high quality. Specialized silage corn varieties should also have good disease resistance, otherwise it will lead to a decrease in yield and also a decrease in silage quality.

At present, China has cultivated a number of silage special corn varieties, and passed the national or provincial variety approval, according to the actual local conditions according to local conditions.

The yield of corn is relatively high, the variety is superior, the corn plant is larger, and the dehydration rate is slower in the process of prescription, it is not easy to dry in the air, the grain is full, and the quality of corn with long green persistence is better. It is necessary to select accordingly according to the growth cycle of corn and the variety of corn.

Excellent quality. 25% starch, 45% neutral detergent fiber, 23% acidic detergent fiber, 7% crude protein.

Corn on the cob is best when it is milky. Peel off the corn coat to see the maturity of the milk and choose.
