Strengthen the management of fertilizer and water Taoyuan, pear orchard and vineyards are based on tree vigor and tree age, and apply 50-100 kg of potassium sulfate compound fertilizer per acre. The vineyard can also apply 50 kg of potassium sulfate per acre, apply more points or radial radiation, and apply fertilizer after fertilization. Watering. Spray 0.4% potassium dihydrogen phosphate two times in combination with fertilization twice at intervals of 10 days. Peach trees summer pruning Summer shoots grow quickly and must be pruned. The main methods are thinning and twisting branches. If there are vacancies in the standing branches of the main branch, they will be twisted when they are semi-woody, weakening the growth and cultivating the resulting branches; if the standing branches are denser, the branches will be sparse from the base. except. At the same time, sparse branches, branches and branches, and cross branches are sparsely removed. More than 3 years, peach trees were sprayed with paclobutrazol in accordance with tree vigor in mid-July, and depending on the growth of the tree, they were sprayed again in late July, so that the growth of shoots was shortened, the internodes were shortened, and flower buds were differentiated neatly. Prevention of pests (1) peach trees. The main diseases and pests are red spider, peach borer, peach aphid, peach leaf miner, aphid, bacterial perforation, scab, anthrax, brown rot and so on. The red spider used avermectin to control and other pests were treated with diflubenzuron. Scab, anthrax, and brown rot were treated with thiophanate-methyl, and bacterial perforation was treated with streptomycin sulfate. (2) Pear trees. The main diseases and pests are black spot disease, black spot disease, pear borer, peach borer, and leaf mite. It can be treated with 50% tetrazine zinc thiram WP (1200 times), 50% carbendazim wettable powder (800 times liquid), and 1.8% abamectin EC (4000 times liquid) mixed spray. (3) Grapes. The main pests and diseases include anthrax, white rot, brown rot, powdery mildew, downy mildew, and red spider. When no leaf disease occurs, 80% Mancozeb WP can be sprayed once every 15 to 20 days for 600 to 800 times; when downy mildew occurs, 69% AZM wettable powder can be used. 72% frost urea manganese zinc wettable powder control; when brown spot occurs, it is treated with difenoconazole and azoxystrobin; when powdery mildew occurs, it is controlled by mancozeb; when there is spider mite, use Control of avermectin; direct cut off of the head of the ear and deep burial.
The RCU is connecting to the server center by TCP/IP and Ethernet protocol, each RCU could is connected to the hotel LAN and has an independent and unique IP address that is compatible with the Ethernet standard.
On the high voltage, there are replay outputs for the electrical equipment, the relays act as the switch and are controlled by the communication board that could receive the instruction from the 12V switches installed in the guest room.
The communication board is the core as the whole RCU like computer`s CPU, it mainly has two functions as below:
Receiving instruction signals from the switches, door plate, and sending signal to the 220V high voltage to turn on/off the lighting fixtures or control the air-conditione
The function of smart RCU as below:With strong stability;Good compatibility; Enhance the quality of hotel services ;Low cost,easy maintenance.
