Choose fertile, flat, easy irrigation and drainage, loose loam soil, well-illuminated land, avoid high dryness. Thin and sandy lands can also be planted in young fruit trees. In the south and the north, seedlings are transplanted and seedlings are transplanted. The temperature in early spring is low, seedlings are late, and the yield is low, which is not conducive to growth.
When sowing the seed with a new high fat film for 12 hours, the time should not be too long, otherwise it will be easy to chaos. Spread the seeds into the thin layer of fine soil to cover the seeds, and spray the new high-fat film evenly to keep the soil moist. Before emergence, we should always keep the seedbed moist, and the relative humidity in the larvae should be kept between 70% and 80%. After the seedlings are flushed, soil moisture should be controlled to prevent the occurrence of damping-off. After the seedlings are rooted, new roots are applied every 15 to 20 days for weeding and topdressing, and topdressing with nitrogen fertilizer is the main method. At the same time, spraying the medicinal material, Zhuang shu ling, can make its stem thick, leaves thick, fresh leaves, and plants flourish.
The disease has blight, with 1-2 pairs of true leaf stages, which can reduce the soil moisture, and then use the tree general 1000 times liquid to irrigate the ward, while controlling the temperature, pay attention to ventilation, and strengthen seedbed management.
High Resolution Distance Sensor
JRT produced the high resolution optical distance measurement sensor for 16 years with lower cost. Our distance measuring sensor have small size, high accuracy.
The laser range finder components is characterized by an above-average measured value output frequency, up to 8hz. The miniature laser distance module is also suitable for monitoring defined distance and height during transport.
