Choose a site for your work. The former pods are best for beans and melons, and the soil must be deep-dried and dried to facilitate drainage and irrigation. After transplanting, spraying a new high-fat membrane can effectively prevent surface water from evaporating, seedling water from transpiration, isolating pests and diseases, and shortening the period of seedling sowing to quickly adapt to the new environment and grow healthily. Shallow planting. In the spring and autumn planting scallions is generally planted at a depth of 4-5cm. Its purpose is to increase the length of scallions and increase the yield and quality of the product. When planting seedlings, it is better to use 3-4 roots per cluster, and the depth should be 2-3cm, and the density should be kept at 5cmx5cm. Suitable shade. After the new high fat film is sprayed, it is covered with a shade net. This can be a cooling 3-5 degrees; 2 can be less evaporation, anti-bacterial infection, to maintain soil moisture; 3 can prevent heavy rain and rain on the surface of the direct flushing, which effectively reduce the degree of surface compaction. Fertilizer management. Chives are underdeveloped roots, shallow distribution, weak water absorption capacity, neither drought nor impatient. Therefore, when it comes to drought, it is necessary to adhere to a small water supply. The timely spraying of vegetables, stems and stems, can make the stem thick, leaf hypertrophy, fresh leaves, plants lush, natural taste. At the same time, it can increase the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual poisons. Disease prevention and control. The diseases of chives include gray mold and viral diseases. Can be sprayed in advance to prevent the new high-fat film, found that the disease in time with a new high-fat membrane with fungicides control. 2022 New Laser Distance Sensor
At the start of 2022, JRT introduce our customers a batch of new series laser distance measurer sensor(S92-20m, S91, BA6A-150m, BA6A-20Hz, M703A-8Hz, U81-10m etc.). Especially S91(RS485 interface and software Rx Tx protocol) and S92(RS232 interface) ip54 enclosure distance sensor model, custoemrs would like to use it in their industrial automation solutions,according to the ip54 waterproof protection level, well protect laser, Wide Voltage 5~32V(Optimize for industrial using), and easy-to-install.
