Seedbed treatment and sowing seedbed soil sterilization treatment, in order to prevent the occurrence of root knot nematode disease, should be used to control root knot nematode disease agents for simultaneous treatment. Select the same size of the germ and separate sowing, soil moisture should be maintained at 60% -70%, after sowing with a new high-fat membrane 600-800 times spray the surface of the soil, moisture can be preserved moisture evaporation, sunscreen drought, insulation, frost, soil layer Compaction, suffocation and isolation of pests and diseases increase the emergence rate. The seedbed soil temperature should be adjusted to about 25 degrees Celsius to provide temperature protection for germ growth. Management after unearthing of seed buds When the seed is unearthed in 75%, the cover shall be removed in time, and the seed buds shall be removed from the seed buds in time to ensure that the cotyledons have sufficient light-filling time so that the cotyledons can be transformed into green as soon as possible, which is beneficial to photosynthesis. The generation. Temperature control When the seed is unearthed more than 80%, the geothermal heating should be stopped. The low temperature control is appropriate at 16-20°C, the night temperature is controlled at 14-17°C, and the room temperature is controlled at 25-32°C during the day, but it cannot be low at night. At 12°C. Pvc X-Ray Thread,Operation Pvc X-Ray Thread,Medical Pvc X-Ray Thread,Surgical Operation X-Ray Thread Shaoxing Weijian Medical Supplies Co.,Ltd. , https://www.wetourmedical.com
