A boom barrier, also known as a boom gate, is a bar, or pole pivoted to allow the boom to block vehicular access through a controlled point. Typically the tip of a boom gate rises in a vertical arc to a near vertical position. Boom gates are often counter weighted, so the pole is easily tipped. Boom gates are often paired either end to end, or offset appropriately to block traffic in both directions. Some boom gates also have a second arm which hangs 300 to 400 mm below the upper arm when lowered, to increase approach visibility, and which hangs on links so it lies flat with the main boom as the barrier is raised. Some barriers also feature a pivot roughly half way, where as the barrier is raised, the outermost half remains horizontal, with the barrier resembling an upside-down L when raised.

Second, remove the old yellow leaves of rapeseed, reduce the source of bacteria, and avoid re-infection. After the old yellow leaves are taken off, they are taken out of the field for pig feed or manure, and the old yellow leaves are not placed in the field.
Third, the drug control 1, take a one-time drug control, prevention and control period in rapeseed flowering plant rate of 100% to a branching flowering plant rate of 80% of the drug, the choice of the formula is 25% so that 100 grams of emulsifiable concentrate 30 ml 40 liters of water spray.
2, taking secondary medication prevention and control, the control period is in the initial flowering stage and full bloom period of rapeseed, the selected agent is 50% carbendazim 100 g / a 40 liters of water spray.
Occurrence and control of Sclerotinia sclerotiorum
First, the prevention of weeds, clear ditch drainage: weeds directly affect the growth of rapeseed and field ventilation, which is conducive to the occurrence of sclerotinia; the accumulation of water in the field affects the roots of rapeseed and reduces resistance. Therefore, farmers should do a good job of weeding and clearing ditch drainage in time to ensure that the rain stops and ditch.
