The spring temperature is suitable, the sun is shining, and the spring blossoms are the best season for sowing. Many people who like to raise flowers choose to plant in spring. However, how the quality of the seed directly affects the flower emergence rate. In order to improve the quality of spring sowing and increase the emergence rate, the following matters should be noted in flower planting:
What should I pay attention to in spring flower planting?
First, whether the seed can germinate depends on four conditions: moisture, temperature, ventilation, and light. After sowing, the soil should be kept dry and not wet. The germination temperature varies depending on the flower, and most of them are 20 ° C ~ 25 ° C, and the soil should be loose when sowing. Seeds with hard cores and seed coats should be treated with sand in winter.
Seeds dried in winter need to be soaked with 100 times liquid of new high-fat film before sowing to increase the emergence rate. Most of the green seedlings are mainly ground sowing, and the thickness of the covering soil depends on the size of the seed. The thickness of the large seed is 2 to 3 times the diameter of the general seed. After seed sowing, spray a new high-fat film 600-800 times liquid to keep the soil moist, keep warm, freeze, suffocate and isolate the source of pests, increase the emergence rate, and pay attention to ventilation and light after emergence.
