Quick Release Pin
Quick Release Pins have a wide range of uses in fastening , locating , and alignment applications. The pins will not release until the button on the handle is depressed. Once the button is depressed, the balls retract into the shank allowing the pin to be inserted or removed into or out of a hole. The shanks are made from 304 or 17-4PH stainless steel. The handles for the pins listed below are made from aluminum alloy and anodized black. Stainless steel handles are also available .The pins are supplied with stainless steel split ring for attaching a cable assembly .Pins in other grip lengths are available as special orders .
The detent pins are designed to use in temporary quick disconnect operations. Used as a convenient way to adjust or remove accessories on equipment. The pin has a ball bearing on one end with a steel spring works that depresses and springs out to lock the pin into place.Rigid quality control procedures ensure a consistent fastener you can count on. Standard sizes are made from low carbon steel,zinc plated, or stainless steel.

1, adhere to the rotation down. To fight melon like good ventilation or sandy soil, with moderate or slightly acidic. Suitable foreland crops are alfalfa, wheat, rapeseed, corn, cotton and sun-dried recreational land, while melons, sugar beets, solanaceous fruits and cucurbitaceae vegetable crops, etc., should not be used as a predecessor to fight melons. To fight melons should not be repeated, otherwise there will be more pests and diseases, and it is better to use 3 to 5 year rotations for better results.
2. Insist on autumn tillage and do full-scale fertilization. Each mu can be 10 kg of three phosphorus, urea, urea, 7.5 kg and 4 tons of farmyard fertilizer is applied into the planting belt 15CM deep. Before the fall, the soil was disinfected with soil fungicide such as carbendazim, quintozene, and chlorhexidine.
3, choose a good seed. The general planting varieties of melons are black, red, red and black. Before sowing, warm water of 55--60°C can be used for soaking in warm soup. When water is poured into the seeds, it must be stirred with water. When the water temperature drops to 30°C, soak the seeds for 20 minutes and remove them with 70% mancozeb or 50 % Carbendazim wettable powder, etc. is seeded at a dry seed weight of 0.3% to reduce the germination and seedling period from germ damage.
Second, the appropriate sowing
1, sowing date: When the 10CM ground temperature stable through 14 °C can be sowing, sowing date in late April - May is appropriate for the middle and late, not later than the end of May.
2, the amount of sowing: artificial or mechanical on-demand can be, about 2.5 kilograms per mu sowing, side planting when diammonium phosphate 5 kg / mu.
3, sowing methods: soil quality is good, fertilizer and water are more adequate, row spacing is generally 1.25 meters, spacing 30CM. Earthy general, take a row spacing of 100CM + 30CM wide and narrow rows, spacing 25CM; weaker land, take a line spacing of 80CM + 30CM wide and narrow rows, groove width 30CM, 70CM film with a ditch and a film, even the ditch with ridge back edge shop together Membrane, with soil sealing, compaction film edge.
Third, seedling management
1, check seedling replant.
2, and time Dingmiao. 2 true leaf leaves and time seedlings, 4 true leaf leaves are planted at the same time, 2 plants per hole. Keep seedlings at a distance from the seedlings, remove diseased seedlings and weak seedlings, and leave seedlings to be uniform and tidy. Generally no seedlings can be filled with 1-2 points, and the seedlings can be planted by the top position method or the vines can be led out to the top of the hole.
3, cultivating loose soil and top dressing. After 15 days of seedling emergence, the first cultivator, the depth of about 12CM, leaving nursery with about 10CM, artificial weeds between the seedlings net. The first piece of real melon leaf after flattening and throwing vines before cultivating top-dressing fertilizer, cultivating fertilization depth of about 16CM, acres of topdressing urea 10 kg. When topdressing fertilizers outside the roots, appropriate sprays of some trace elements are added to prevent disease and increase production.
Fourth, early prevention of disease, clever foliar fertilizer
