Guizhou has a subtropical monsoon climate and a subtropical humid monsoon climate. There are four distinct seasons here, with sunny spring and abundant rainfall in summer. Because Guizhou belongs to Kashite landform, there are many mountains and uneven terrain, so it is not easy to develop farming economy. Comparatively speaking, it is more suitable for developing animal husbandry.
In order to develop animal husbandry well, it is necessary to solve the daily forage problem of animal husbandry. The selected forage seeds can not only adapt to the local temperature and climate, but also support the growth of forage in multiple seasons, which solves the forage problem in spring, summer and winter to a great extent and saves a lot of costs for farmers.
On the whole, alfalfa, ryegrass and Pennisetum are the most suitable forage seeds for planting in Guizhou, because these three forage seeds can completely match the above main characteristics, and they are rich in nutrients such as crude protein, crude fat and crude fiber, which are beneficial to the growth of livestock, and livestock like to eat these grasses very much.
Alfalfa is a perennial legume feed, and it is also the most planted feed variety in China and even the world. Because of its strong adaptability, high yield and good quality, it is known as the "king of feed". According to different regions, different management levels and different mowing time, the yield of alfalfa varies greatly, and it can be mowed about three times a year.
Compared with alfalfa, ryegrass has a longer growth cycle and can be planted in spring, summer and winter all year round. There are many tillers and strong regeneration ability. After harvesting and grazing, it can quickly resume growth, and the general life span can reach 4-5 years. Moreover, the forage grass is soft, smooth and of good quality, which is suitable for all kinds of herbivorous livestock.
Pennisetum also has a wide feeding range. For example, pigs, cows, sheep, rabbits, geese, fish and other animals can be fed. It is a perennial herb with a plant height of about 120~280cm. It has low requirements on the growing environment and can grow on the edge of trees, bushes or sparse forests.
Summary: Generally speaking, alfalfa, ryegrass and Pennisetum are more suitable for planting in Guizhou. Of course, there are other forage seeds that are also suitable for growing in this climate in Guizhou, such as: duck grass, African dog tail grass and so on.
