Alfalfa, also known as purpura, is a perennial herb of the family Leguminosae. The growth period is 5-7 years. The main root is thick and long. It is 2-5 meters deep into the soil and 30-60 cm long. Stems erect, plant up to 60-120 cm. Because of its high nutritional value, good palatability, strong drought resistance, and good cold resistance, it is widely cultivated and is known as the “Queen of Pastureâ€. Aster seedlings are thin and weak, and they grow slowly at seedling stage. Therefore, it is necessary to carefully set up the soil before sowing. Except for weeds and grass weeds, open the drainage ditch, and do a good job on Panasonic. The soil with poor fertility should apply 20-50 mash per acre. The acidity of soil should be applied before the sowing in January-February: the soil PH value is 5-6, 10-20 kg per mu; the PH value is 4-5, 40-80 kg per mu. This is because the pH value of soil suitable for earthworms is 6.5-7. Seeding method: drill and broadcast can be sowing depth of 0.6-1.3 cm, row spacing 15-30 cm. Unicasting 0.8-1 kg per mu. Mixed with other crops, the amount of seed can be appropriately reduced; both spring and autumn sowing can be. Asters are most suitable for the first flowering period, when both the nutritional value and the amount of grass production are high. One year can be castrated 3-4 times, leaving a height of 4-5 cm is appropriate. The yield of fresh grass can reach 3,500 kg. In terms of dry matter, the crude protein content is more than 20%. Lotus roots are perennial quality legumes suitable for grazing, hay and silage. Perhaps because of the presence of tannins, Lotus root does not cause bloat in livestock. Lotus roots generally grow for 6-7 years. The stems of adult plants grow from the root neck, and the stems are more branched. Under the right conditions, the main stem can be as long as 60-90 cm, and it can be bred with cuttings from the stem. Compound leaves, petiole length 3-15 mm, 3 leaflets born on the petiole apex, 2 stipules born at the base of the petiole, it is also known as the shamrock. Capsicum oblonga, with 10-15 seeds per pod, turns brown or nearly black when mature. Seeds are small, with only 1-1.2 grams of 1000-grain weight. Lotus roots are warm and humid, and their heat-resisting ability is slightly stronger than that of purpura. Their drought tolerance is slightly worse than that of red clover and white clover. Resistant to moisture, resistance to trampling and strong regeneration. In the southern mountains, it is a better grass species. Due to the slow growth of seedlings and the weak competitiveness of weeds, soil preparation at the time of sowing should be fine. Before sowing, seeds need to be soaked to increase germination. Spring broadcast can be broadcast autumn. The amount of 0.5-1 kg per mus for unicast is appropriately reduced when mixed. Suitable for drilling, broadcast depth 1-2 cm, spacing 30-40 cm. It is best to mix it with gramineae, such as mixed with Italian ryegrass and white clover. Phosphate seed dressing can increase production. Lotus roots can be castrated 2-3 times a year, preferably 8-10 cm. Only seedlings can be cast for two times. The output can vary greatly depending on the conditions and the maximum yield per mu can reach 5000 kg. Lotus roots have high nutritional value and are comparable to earthworms. Grazing, drying hay and silage are all acceptable. The use of fresh grass should prevent the generation of hydrocyanic acid due to the accumulation of rot. Because most Lotuses contain cyanogenic glucosides, free hydrocyanic acid is produced by enzymatic hydrolysis, and hydrocyanic acid is toxic to livestock.
