The method of breeding of clover
soil
The seeds of clover are relatively small, so the unearthed power is weak and the seedlings are relatively slender, so it grows slowly in its seedling stage. Therefore, before sowing, the soil must be reorganized, the soil is shallow and clearing the debris, making the soil block finely. At this time, the soil becomes loose and conducive to sowing.
Sowing and seed treatment
The best sowing time for clover is spring and autumn. The appropriate sowing temperature should be 19-24 ° C. When the temperature of the spring is stable in the spring of 15 degrees Celsius, the sowing can be sowed in mid-late September. Win the seeds before sowing, and the sowing depth is 1-2cm. If it is too depth, it may not be easy to emerge.
Postpone management
Before the seedlings are sowed after seedlings, if the soil is knotted, timely loose work should be done to facilitate the emergence. Because the three -leaf grass seedlings grow slowly, it is very vulnerable to the infringement of weeds. The seedling stage should be weeded 1 or 2 times; in addition, the diseased and insect worst pest control of clover must be done to ensure the smooth growth of the clover. When the soil is dry, keep water to maintain work, and keep the soil moist more conducive to the growth of clover.
Fertilize
Three -leaf grass belongs to the bean family, so it has nitrogen fixation, but in its seedling period, a small amount of nitrogen fertilizer is needed to benefit strong seedlings, otherwise the plants will be short and yellowish. After the seedlings are strong, you can also apply measuring phosphorus and potassium fertilizers.
Precautions for breeding of clover
Pest
The diseased and insect pests of the clover will be more common. Cobacolic disease and virus infection are the main diseases of the clover. If the clover suffers from the disease, we can pull out the diseased plants and sever the disease. The second is to use chemicals. Pests are more common in leaf cicada, land tigers, white powder butterflies, etc. These insect pests need to use special pesticides or pesticides for killing.
