Breeding method of clover
Soil
The seeds of clover are relatively small, so the unearthed force is weak, and the seedlings are relatively thin, so they grow slowly at the seedling stage. Therefore, before sowing, we must straighten the soil, turn the soil shallowly and remove the sundries, so that the soil becomes finely broken. At this time, the soil becomes loose and conducive to sowing p>
Sowing and seed treatment
The best sowing time of clover is spring and autumn, and the appropriate sowing temperature should be 19-24 ℃. Sowing can be carried out when the temperature is stable above 15 ℃ in spring, and in mid and late September in autumn. Before sowing, the seeds should be soaked. The sowing depth is 1-2cm. If it is too deep, it may be difficult to emerge p>
Post planting management
If the soil hardens after sowing and before emergence, timely loosening should be done to facilitate emergence. Because clover grows slowly in the seedling stage, it is very vulnerable to weeds. Loosen the soil and weed for 1 ~ 2 times in the seedling stage; In addition, we should do a good job in the prevention and control of diseases and pests of clover to ensure the smooth growth of clover. When the soil is dry, it is necessary to do a good job in water conservation to keep the soil moist, which is more conducive to the growth of clover p>
Fertilization
Clover belongs to leguminous plants, so it has the ability of nitrogen fixation. However, in its seedling stage, it is still necessary to supplement a small amount of nitrogen fertilizer, which is conducive to strong seedlings, otherwise the plant will be short and the leaf color will be yellow. After the seedlings grow strong, a certain amount of phosphorus and potassium fertilizer can also be applied
precautions for clover culture
diseases and insect pests
diseases and insect pests of clover will be more common. Sclerotinia and virus infection are the main diseases of clover. If clover suffers from diseases, first, we can pull out the diseased plants and cut off the source of the disease, and second, we can use chemicals. The more common pests are leaf cicada, ground tiger, white powder butterfly, etc. these pests need to be eliminated by using special pesticides or pesticides
