1. Seed treatment: Seedlings in summer due to low seedling emergence, seed cold treatment should be carried out. The method is to soak the seed for 12 hours, then wrap it in the refrigerator (2°C-5°C) for 2 days, and then spread it in the cool place until the seed cracks and germinates before planting.
2, sowing: sowing should be to prevent uneven density, before sowing should be enough to water 1 time; sowing 3 grams per square meter -3.5 grams; in the ground cover shade net cooling, moisturizing, expelled after emergence.
3, seedbed management: summer nursery should prevent rain shower and high temperature and drought, rain seedlings and shade net can be used to cover nursery. The shade net is usually covered in the morning from 8 am to 4 pm on sunny days and it can be uncovered at night or on cloudy days. Dry weather should be watered more in the morning and evening, and can be top-dressed with watering.
Brand computer chips, dual-frequency integrated circuits, cross-magnetic induction detection, bringing higher accuracy, reliability and stability. 2. Automatic control system, using special magnetic materials and unique technology, the detection accuracy of the probe is particularly high, and the accurate position of the broken needle is displayed in 8 detection areas. 3. Dual probe design, double detection function, higher safety performance, compared with other types of needle detectors, at the same detection height, the sensitivity is increased by 10%. 4. Automatic detection, automatic induction, automatic stop when no detection is needed, 0-10 sensitivity adjustment, when there is a broken needle, the conveyor belt automatically stops and returns backwards. 5. With a counting function, it can count the number of qualified or unqualified products. 6. It has two alarm modes: sound effect and light alarm. 7. Luxurious appearance, novel style, time-saving and power-saving, simple operation
