Clover can be divided into two types according to different colors, generally white and red. Clover likes a warm and well drained environment, but it can't bear the dry environment, and it's not conducive to its growth in the high temperature environment. Clover contains a lot of minerals and protein, which is a very high quality forage. It can adapt to the growth of both acid and alkaline soil. It has a very promising future in China. If managed properly, it can last for more than seven years. Clover belongs to Leguminosae, which has strong nitrogen fixation ability. When selecting fertilizer, it can generally choose a small amount of nitrogen fertilizer. In addition, phosphate fertilizer, potassium fertilizer, urea and other fertilizers also contribute to the increase of clover yield.
The seeds of clover are very small and the growth ability of seedlings is very weak. It usually takes a long time from sowing to sprouting. In order to ensure the normal development of seedlings, careful care must be taken. Whether sowing in spring or autumn, the land shall be leveled in advance, and then deep ploughing shall be carried out every 10-15 days, and the soil shall be finely broken and waiting for sowing. Before sowing, fertilizer should be applied once. Generally, organic fertilizer mixed with superphosphate is used as base fertilizer after being stirred evenly. A small amount of nitrogen fertilizer can be applied at the early stage of sowing to promote the growth of seedlings. If the plants are short and small and the leaves turn yellow when they emerge, the amount of nitrogen fertilizer should be increased appropriately. In general, 15 days after the emergence of clover, urea, potassium, calcium magnesium phosphate fertilizer should be applied, which is conducive to improving the grass yield.
Generally, clover is sown in spring and autumn, and the temperature is best between 19-24 ℃. The seeds of clover must be soaked before sowing. In general, it is recommended to add 1.5kg water to every 1kg of seed, add 1g ammonium molybdate to soak the seed for 12 hours, and then add 5-10kg calcium magnesium phosphate fertilizer to fine soil or 5-10kg yellow sand to mix them before sowing.
