The seeds of clover are relatively small, so the excavation force is weak, and the seedlings are relatively thin, so the growth is relatively slow at the seedling stage. Therefore, before sowing, we must prepare the soil, turn the soil shallowly and remove the sundries, so that the soil becomes fine, and then the soil becomes loose and conducive to sowing.
The best sowing time of clover is spring and autumn, the suitable sowing temperature should be 19-24 ℃, when the temperature is stable above 15 ℃ in spring, sowing in autumn can be in mid late September. Before sowing, the seeds should be soaked. The sowing depth is 1-2cm. If it is too deep, it may not be easy to emerge.
If the soil hardens after sowing and before emergence of clover, timely loosening should be done to facilitate emergence. Due to the slow growth of clover in seedling stage, it is very vulnerable to weeds, so the soil should be loosened for weeding once or twice in seedling stage; in addition, the disease and pest control work of clover should be done well to ensure the smooth growth of clover. In the dry soil, to do a good job in water conservation, keep the soil moist is more conducive to the growth of clover
Clover belongs to legume, so it has the ability of nitrogen fixation. However, in its seedling stage, a small amount of nitrogen fertilizer should be added to help the strong seedlings, otherwise the plant will be short and yellow. After the seedling is strong, still can apply quantitative phosphorus, potassium fertilizer..
The diseases and insect pests of clover are quite common. Sclerotinia and virus infection are the main diseases of clover. If clover suffers from the diseases, we can pull out the diseased plants and cut off the source of the diseases. Secondly, we can use chemical agents. Insects are more common cicadas, tigers, butterflies, and so on, these insect pests need us to use special pesticides or pesticides to kill.
