——Preface·]—
China's aquaculture industry continues to expand the scale in order to meet the growing demand for meat in the market, although the rapid expansion of the aquaculture industry is a good thing, which means that the development prospects of the aquaculture industry are bright, but it should also be noted that at the same time of rapid expansion, the aquaculture industry is also facing many problems.
Among these problems, the most prominent one is the issue of feed for livestock. China imports a lot of grain every year, and a large part of this grain is used for feed production. Faced with the problem of lack of feed for livestock, more and more people are aware of the importance of pasture cultivation. Among the many types of forage, there is such a forage grass.
Its production is very impressive, and its internal nutrient content is extremely high, and it has a majestic nickname in the industry - "plant gold mine". So, why did this forage get the nickname "plant gold mine"?What is its true identity?
——High-quality pasture grass-leaf-eating grass]—
In order to expand the diversity of livestock feed, solve the necessary problems brought about in the expansion of the breeding industry. Many forage breeding companies have begun to invest heavily in R&D costs. Among the many forage grasses, suitable forage grasses are selected and then cultivated artificially.
After careful selection by relevant experts, they finally selected a forage variety with equal development in all aspects of the vast forage group. This excellent pasture grass is the famous "leaf-eating grass". What is a leaf-eating grass?
Leaf-eating herbs are biologically classified into the family Polygonaceae, and in the downward division, they belong to the genus Sorrel. The most important feature of plants in this genus is that plants of this genus have many leaves, and these leaves are also very large.
Just from the appearance, you can see that the leaves are also very large, and the height of the leaf-eating grass is also very impressive. This appearance has many similarities with other plants of the genus Sororax. It is important to note that leaf-eating herbs are not congenital plants. In other words, leaf-eating grass is the product of artificial technology, not a plant that nature is born with.
Scientists and technicians carried out continuous screening and hybridization among many plants of the genus Sororrel, and finally succeeded in cultivating the existing leaf-eating grass. Therefore, the biological Xi of today's leaf-eating grass, including its growth characteristics and practical use, are all artificially screened and cultivated, with a specific purpose.
Leaf-eating grass is a plant that has many aliases, the most well-known of which is the nickname "protein grass". The reason why leaf-eating grass is called "protein grass" by the public is mainly because the amount of protein inside the leaf-eating grass is so amazing. According to relevant studies, the protein content of leaf-eating grass is basically maintained at a ratio of 30% to 40%.
This protein percentage is very staggering among all kinds of grasses. It also gave leaf-eating grass the reputation of "protein grass". The nutrients inside leaf-eating grass are not only protein. In fact, the types of various nutrients in leaf-eating grass can basically meet the daily needs of the human body.
The high content and variety of nutrients are concentrated in a kind of forage, which can save them a lot of expenses and reduce the cost of feed for livestock industry practitioners. Basically, it is a kind of forage grass that can meet the daily energy needs of livestock, and it is also conducive to the growth of livestock, which is a very excellent forage species.
Because of this, leaf-eating grass has successfully stood out from many kinds of forage grasses and has become a very excellent forage variety in the eyes of breeding workers. Let the leaf-eating grass gain a resounding nickname in the industry, that is, the majestic "plant gold mine".
——Planting conditions of leaf-eating grass·]—
The nutritional value of leaf-eating grass itself is very high, which naturally attracts many farmers to grow it. But it is important to understand that a forage grass can be welcomed by the industry in addition to its own excellent qualities. Another point is that leaf-eating grass must be easy to grow. This is understandable, as leafy grass can be difficult to grow, even if it has high levels of nutrients.
After careful calculation, it is not cost-effective for farmers to plant leafy grass. After a long period of cultivation, the growth Xi of leaf-eating grass itself is also very good.
Leaf-eating grass is very life-strong, and because it is a perennial plant, it also means that leaf-eating grass grows new shoots every year, and it does not require a lot of manpower to sow seeds in the spring. With a life span of more than 20 years, for farmers, it can tone up a large amount of planting costs, which greatly reduces the production costs of farmers.
Secondly, the vitality of leaf-eating grass is very strong, and it has a certain resistance to cold and humid climates. Such growth Xi promotes the growth range of leaf-eating grass on an innate basis.
You must know that there are long winters in the northern regions of our country. Cold climates are actually a fatal injury to plants. After all, if it weren't for that kind of alpine plant, basically other plants would not be able to survive the winter.
What's more, in winter, the soil in northern China will also turn into permafrost, which is the famous seasonal permafrost, which brings a fatal blow to plants that are already difficult to grow.
The reason why leaf-eating grass grows in the north is that it can survive the cold winters. Relying on its own well-developed root system, the root system of leaf-eating grass is very developed. This provides a rich amount of energy for the leaf-eating grass in winter, and the leaf-eating grass will wither in the winter, in fact, wilting is also the hibernation of a plant.
The following spring, when the climate warms up, the leaf-eating grasses that have stored energy will sprout new shoots on the plants that withered the previous year. Therefore, the distribution range of leaf-eating grass in China is very broad, and it can be planted in both the north and the south. This allows leafy grass to lower the threshold for planting and enter the eyes of farmers.
Finally, leaf-eating grass is not very demanding on the soil, in other words, leaf-eating grass is not picky about the quality of the soil. Leaf-eating grasses can also grow in acidic and alkaline soils. In addition, the yield of leaf-eating grass is amazing, even in the cold north, it can be harvested except in winter.
In the south with a warm climate, it can be harvested all year round, which mainly depends on the very fast growth rate of the leaf-eating grass itself, basically about 20 days, you can harvest a wave of leaf-eating grass. The annual constant of leaf-eating grass can reach a minimum of more than 20 tons, and the average harvest at this time is not uncommon for a higher harvest than this data.
- Disadvantages of leaf-eating grass ·] —
As the saying goes, "There is no such thing as perfection in the world", there are many advantages of career Ao, but this does not mean that leaf-eating grass has no disadvantages. The disadvantages of leaf-eating grass, although not many, are also very typical. The first disadvantage is that leaf-eating herbs are not easy to store and are very perishable.
Leaf-eating plants are not picky about the soil, and they are also resistant to cold and heat. But leaf-eating grass has a fatal biological defect. This defect is that the resistance of leaf-eating grass to floods is very low, and if a flood occurs, the natural enemies of leaf-eating grass planting are soaked in large waters.
Then, soon the roots of the leaf-eating grass will decay accordingly, and once the decay occurs, the leaf-eating grass will have no way to feed the livestock. I'm sure many people will ask, isn't it okay to harvest leaf-eating grass quickly and then put it in a dry warehouse?Leaf-eating grass is actually a very difficult forage grass to preserve, mainly because the protein content of leaf-eating grass is very high.
High protein is also a double-edged sword, on the one hand, it is good for livestock, and on the other hand, it is a source of insect infestation and rot. Many pests are attracted and begin to nibble on the harvested leaf-eating grasses. Even with insect control in place, the grass will start to rot on its own.

In general, leaf-eating grass is a forage grass with many advantages and great advantages for the breeding industry. But the disadvantages of the corresponding leaf-eating grass are also very typical.
