With modern machinery processing industry development, for the continuous
improvement of quality and accuracy of cutting, to improve the production
efficiency, reduce production cost, high intelligent and automatic cutting
function requirement also is increasing. The development of CNC Cutting machine
must adapt to the request of the development of modern mechanical processing
industry. Cutting machine flame cutting machine, plasma cutting machine, laser
cutting machine [1], water cut, etc. Laser cutting machine for the efficiency of
the fastest, the highest precision cutting, cutting thickness is generally
small. Plasma cutting machine cutting speed quickly, cutting surface has a
certain slope. Flame cutting machine for greater carbon steel in the thickness
of the material..
classification Cutting machine pictures Cutting machine pictures Cutting machine
to distinguish from cutting material, divided into metal cutting machine and
nonmetallic material cutting machine. Metal cutting machine flame cutting
machine, plasma cutting machine, laser cutting machine, water knife cutting
machine, etc.; Nonmetallic material cutting machine cutting machine mainly
tools. Cutting machine to distinguish from the control way, divided into CNC
cutting machine and manual cutting machine. CNC cutting machine Is to use
digital process driven machine movement, as the machine tool movement, random
matching of cutting tools for cutting objects. The mechanical and electrical
integration of cutter is called the CNC cutting machine. Laser cutting machine
for the efficiency of the fastest, the highest precision cutting, cutting
thickness is generally small. Plasma cutting machine cutting speed quickly,
cutting surface has a certain slope. Flame cutting machine for greater carbon
steel in the thickness of the material. Range of application Cutting machine
used with metal and nonmetal industries, in general, nonmetal industry points
more meticulous, as there is

Non-pollution cucumber production technology
Variety selection choose disease-resistant, high-yield, high-quality varieties. For varieties such as Jinza No.2, Jinza No.4, Jinchun No.2, Jinchun No.4 and Jinyou No.10, sowing date selection is determined according to market demand and biological characteristics. Cucumber cultivation in the spring (film) is usually done with a cold bed or a nursery with nutrients. After the frost is broken, it is transplanted into the field. Summer cucumber can be broadcast live. Late autumn cucumbers are sown 90 to 120 days before the early frost. The spring cucumbers are covered with plastic film covering the open field and sown from late February to early March. Summer cucumbers are sown from early April to late May. Autumn cucumber 6 to July sowing. Sowing seedlings (1) Live broadcast: Apply enough base fertilizer before sowing; Soaking seed germination, soaking in warm water at 50 °C, until the water temperature dropped to 30 °C, maintain a constant temperature, continue to dip for 5 to 6 hours. After soaking, the seeds were washed lightly, wrapped in clean wet gauze and kept germinating at 30°C. Can be placed in the jar or porcelain plate, maintain a certain humidity, on the stove for two days and nights, you can sow after budding. 250 grams per 667 square meters, 2 to 3 seeds per hole. After sowing watering, covered with plastic film. (2) Seedling: Seedlings are raised with seedling trays. The substrate is made of clean sandy loam soil or humus soil, mixed with a small amount of mature manure, and put in the pan, slightly shallow. Put the germinated seeds in the hole, 1 per hole, and then Cover the substrate, irrigating the water, spray with less bacteria and insecticide, 4000 plants per 667 square meters, 80 to 100 grams of seeds. Field management (1) Seedling period: live, break the membrane twice, first open a small hole, wait until the seedlings adapt a few days before opening the mouth, pull out the melon seedlings, seal the hole with fine soil. When transplanting seedlings, true leaves and leaves are colonized. In addition to guaranteeing certain humidity during the seedling stage, the seedlings were poured with diluted fecal water for 1 time. (2) Pumping vines: early scaffolding, timely management of vines on the shelves, dominated by vine vines, side vines destroyed as soon as possible: (3) melon period: this period is the period of maximum fertilizer, water and fertilizer should be guaranteed Promote organic fertilizer. The pests and diseases in this period are heavy, especially the spring cucumber, which is in the harvesting period and chemical pesticides are banned. Pest prevention and pollution-free production, adhere to the "prevention-based, comprehensive prevention and control" approach, give priority to the use of agricultural measures. (1) Agricultural measures: It mainly controls powdery mildew, blight, wilt, root knot nematode, downy mildew, and gray mold. 1 thoroughly clean the pasture before sowing, remove the broken branches and leaves, deep soil over 30 cm to reduce the source of bacteria. 2 The cultivation of the protected area adopts anti-fog dripping membrane covering. 3 Apply rotten organic fertilizer and apply top dressing timely. 4 Cultivation of sorghum to reduce soil moisture. Spread the film or wheat straw, wheat stubble to reduce the relative humidity of the space. 5 selected strong seedlings colonized, with soil transplants to avoid injury. 6 The diseased leaves were removed in time and brought out of the field for centralized treatment. (2) Chemical control: 1 spotted fly can be trapped by yellow plates, or a certain amount of sensitive crops such as broad bean and calamari can be planted around the cucumber, and can be killed by concentrated drugs or sprayed with 1.8% abamectin 2000 times. 2 Aphids can be used once again with a net 2000 times solution or Confodox. 3 Downy mildew can be used to control 53% of Ledomile: 4 Bacterial angular spot can be used to control. 5 The disease can be controlled with radommil or metalaxyl zinc; it is banned 10 days before harvest.
