Seedling cultivation
Also known as Pentagon acerifolia, color wood, banyan tree deciduous deciduous trees. The trees are beautiful, the branches and leaves are dense, the leaves are beautiful, the leaves are red, and they turn into orange or red in autumn, which is very beautiful. The Zhangjia County Fengjia Town Nursery has been carrying out trials for the cultivation of S. mutabilis for many years. After continuous exploration, it has begun large-scale nursery production. The nursery techniques are summarized below. 1. Select the color seedlings of nursery seedlings to be moist, deep and fertile. Therefore, sandy soils with flat topography, deep soil, loose soil, and well-drained water should be selected as breeding grounds. 2, careful preparation, fertilization, deep-fall 25-30 cm in autumn, fine-grained in the spring, so that the land leveling, soil broken, smooth ground, combined with 5,000 kg of basal fertilizer applied per acre. 3, sowing in mid-April. Take a bed for seeding, sow the depth of 4-5 cm, sowing 4-5 cm, and the sowing rate of 20-25 kg per mu. Before the seed sowing, it is best to accumulate germination by wet sand layer. The seed germination of wet sand layer has high germination rate and rapid emergence of seedlings. Seed should be uniform under the sowing, cover soil 2-3 cm after sowing, and then suppress 1 times. 4. Seedling management After 2-3 weeks of seeding, the seed germination and unearthed, and the seeds of wet sand layered accretion can be unearthed in advance. 3-4 days after the unearthing, the true leaves grow, and they emerge within 1 week, and the seedlings begin after 3 weeks. The fast-growing seedlings are topped with chemical fertilizers 2 times, and each time, 10 kg of ammonium bicarbonate is chased. Seedling irrigation 5-6 times, timely soil weeding, keep the bed moist, loose, no grass. The 1-year-old seedling height can reach 70 cm, and the 2-year-old seedling can reach 120-150 cm. Each year, 18,000 seedlings per year are produced. Transplantation and cultivation of 2-year-old transplanted seedlings should be transplanted in spring and spring, with about 6,000 strains per acre, and one row of large ridges. To cultivate more than two years old seedlings, in addition to strengthening the field management measures such as water and fertilizer, loose soil weeding, etc., we must pay attention to dry cultivation, trim side branches, and make the height under the branches reach a fixed height. At the same time, we should strengthen the crown trim. 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.
