The LED Trunking
System is divided into two parts, one is the trunking, the other is the
functional component. At present, for trunking, we have 3 wires, 5 wires, 7
wires, 8 wires and 11 wires. The functional components include the emergency
driver, Motion sensor module and track module.

Non-polluted fertilization technology for cultivation of leeks in open field
The root strain should be cultivated in the cultivation of amaranth in the open field, and the root strain can be cultivated by means of direct seeding or seedling raising. At present, most of the domestic areas adopt the seedling raising method. The amaranth occupies less land during the seedling period, is easy to manage, has few grass damage, and has strong roots and long life.
1Cultivate strong seedlings: When using seedbed seedlings, the seedbed should be selected from the high dry land where the dry energy can be poured, the cockroach can be discharged, and the leeward sunny side. The soil of cotton and onion and garlic vegetables has not been planted within 3 to 4 years. Fertilizer 60,000 to 75,000 kg / ha, superphosphate 600 kg / ha, plant ash 1500 kg / ha or combined application of nitrogen, phosphorus, potassium compound fertilizer 750 kg / ha. After fertilization, the depth is 20 to 25 cm, and the sputum is fine and flat. Select a sunny day for 1 to 2 days before sowing to increase the germination rate and germination potential. Choose high-quality, high-yield, disease-resistant, stress-resistant, adaptable, and good-quality amaranth varieties, such as 791, Pingyi 2, Shouguang Majie, Hanzhong Donglu, Beijing Wire Miao, Hangzhou Xueyan, Shanhaiguan Iron Wire Miao and so on. The seeds were immersed in warm water at 55 ° C for 10 minutes or with 600 times carbendazim for 30 minutes. The seeds sterilized by the chemical solution are washed with water, and then immersed in warm water at 30 ° C for 24 hours, then moisturized and germinated, and can be sown after 2 to 3 days. After 10 to 15 days after sowing, the seedlings should be timely watered, topdressed, weeded and treated. Seedling seedlings take about 60 days, during which watering and topdressing are combined 2 to 3 times, each time with 150-300 kg/ha urea or 150 kg/ha of diammonium phosphate. Seedlings have 7 to 9 leaves, and when plant height is 18 to 20 cm, they should be planted at the right time.
2 Heavy application of base fertilizer, timely planting: Although the leek is more adaptable to the soil, the production of pollution-free amaranth products has strict requirements on the soil environment. You should choose a plot that is 1000 to 2000 meters away from the pollution source and has not planted cotton and onion and garlic vegetables within 3 to 4 years. It is best to plant cabbage, spring cauliflower or cabbage. After harvesting the former crops, the garden should be cleaned in time and shallowly ploughed. The plot of the amaranth planted in the open field is preferably no less than 150 meters from east to west. There should be wind barriers in the north. Wind barriers and landscaping should be east-west. After the cockroach is completed, the fully decomposed high-quality organic fertilizer is applied to 60,000 to 75,000 kg/ha, the diammonium phosphate is 300-450 kg/ha, and the ash is 1,500 kg/ha, and the soil is mixed and the soil and fertilizer are mixed. Generally, it is suitable to plant 3 million to 4.5 million plants per hectare. The overwintering ability and the growth of amaranth mainly depend on the amount of nutrients accumulated by plants before winter, and the accumulation of nutrients depends on the growth of amaranth in autumn. Therefore, fertility management should be strengthened during the seedling stage. Generally, water is poured once every 5 to 7 days, and the quick-acting nitrogen fertilizer is applied in combination with watering for 2 to 3 times. Each time, urea is applied to 150-225 kg/ha or diammonium phosphate 150 kg/ha, and finally 1 time of dilute water is 15000. Kilograms/ha. Before wintering, it is mainly rooting and raising trees, laying the foundation for the spring harvest in the second year. After the spring of the second year, a layer of decomposed organic fertilizer can be applied to the surface of the 750 kg/ha. More than two years old root leeks should also cover about 2 cm. Conditions can also be taken to remove roots, tightness, soil and other measures, can increase ground temperature, sunburn, loose soil, promote root growth, prevent lodging and rotten roots. If it is not fertilized in winter, it is necessary to re-apply the soil and fertilizer in the spring, and the mature soil fertilizer is 22,500 kg/ha, and it is sprinkled on the surface of the glutinous rice 1 to 2 cm to facilitate the leek to jump. After spring fertilization, generally do not water, if the weather is dry, you can water the seedlings after 10 cm, do not follow the water, especially not to apply quick-acting nitrogen fertilizer. If the rain and snow are more in winter and the soil moisture is better, you can start watering after the first harvest, and then loosen the soil in time. Appropriate topdressing when new leaves grow 3 to 4 days after each harvest, apply 150 kg/ha of compound fertilizer or 15000-22500 kg/ha of high-quality decomposed organic fertilizer. In summer, the temperature of the leaves is increased, the texture of the leaves is rough, the growth is weakened and the phenomenon of rest is observed. Generally, it is no longer harvested, and the root culture should be further strengthened to lay a good foundation for autumn production. For perennial leeks, weeds should be controlled by water control and pest control. The cool autumn climate and large temperature difference between day and night are the best season for amaranth growth and the best time to cultivate roots. During this period, the physiological activity was the strongest, especially in the autumn to autumn, it was necessary to re-apply the fertilizer water to promote its vigorous growth. Before and after the beginning of autumn, each time high-quality decomposed manure dry 15000 ~ 22500 kg / ha or bean cake 7500 kg / ha or diammonium phosphate 600 ~ 750 kg / ha, zinc sulfate 15 kg / ha, water 5 times 7 days interval , even pouring 2 to 3 times, topdressing 2 to 3 times. When conditions permit, the plant ash can be applied 1500~2250 kg/ha. Harvest 1 or 2 times between late August and late September. After entering October, watering and topdressing should be stopped, and the drought should be used to control the growth of leeks, forcing the nutrition to accelerate to the bulbs and roots to ensure safe wintering.
