Alfalfa is most suitable for planting in Xinyang, Henan Province, with a month of 1 and high yield. Alfalfa is a perennial leguminous forage, with a short growth period of 4-5 years and a long growth period of 10 years or more. Alfalfa has wide adaptability and high grass yield. Generally planted in low-lying land, the yield of fresh grass can reach 2000 ~ 3000 kg. Planting in high-yield fields can reach 4500 ~ 5000 Jin.
2. Good quality: An important sign of good quality is high protein content, and the crude protein content of alfalfa can reach 18% ~ 22%. Alfalfa is an important feed source in protein. Compared with corn, the protein content of corn is 8% ~ 9%, and the protein content of alfalfa is 1 ~ 1.5 times higher than that of corn.
3. Alfalfa is an important energy feed: although its calories are not as high as corn, from the comprehensive balance of protein and energy, 1 kg alfalfa can at least top 1 kg corn.
Alfalfa also contains some substances that are very beneficial to domestic animals. Now scientists call it an "unknown growth promoting factor". If alfalfa is fed to sows, it will not only save food, but also make pigs give birth to more babies and have a high survival rate. Raising boars and feeding fresh alfalfa can also get good results. If you feed the laying hens, it will not only deepen the color of the yolk, but also increase the egg production. Of course, scientists are still studying this.
5. High ecological benefit: planting alfalfa has a good effect on improving soil and fertile fields. It can carry out biological nitrogen fixation by rhizobia and determine its nitrogen fixation ability. After planting for several years, on a relatively thin acre of land, the land will grow longer and fatter. Because it is a perennial plant with developed roots, it also has the function of preventing soil erosion. Soil erosion control in China Loess Plateau. It advocates planting forage grass, among which alfalfa is one of the important forage grass.
6. Alfalfa can be further processed to extract leaf protein, and its protein content can reach more than 50%, which can be added to human food as a food additive.
Botanical characteristics
Alfalfa is a perennial herb of alfalfa in Leguminosae. The growth life can reach 20 ~ 30 years, with the highest growth in the second to fourth years, and the productivity gradually decreases after the fifth year.
Alfalfa has developed root system and stout taproot, and the buried depth can reach more than 10 meter. The root neck is slightly enlarged at the upper end of the root, which is the place where branches and overwintering buds are planted. It is located in the soil layer 3 ~ 8 cm below the topsoil and extends downward with the cultivation years. Alfalfa has strong cold resistance and grazing tolerance, which is related to this. The stem is erect and smooth, and the height is above 100 ~ 150 cm. Generally, the root neck has 25 ~ 40 branches, and the number of branches exceeds 100. Tripartite pinnate compound leaves, obovate or oblong leaflets, serrated apex, long and pointed stipules. There are many leaves, and the leaves of the whole plant account for 45% ~ 55% of the weight of fresh grass. The raceme consists of twenty or thirty small flowers with purple or deep purple flowers. Cross-pollinated plants are mainly insect vectors, and some promote keel opening through mechanical force collision. When the temperature reaches about 30 degrees Celsius, the keel can also open itself. The pod is spiral, with 2-4 circles, and each pod has 2-8 seeds. The seeds are kidney-shaped, yellow, with 1000-grain weight 1.5 ~ 2g.
