Loofah flowers also need to "freckle"? !
As the weather gets warmer, many summer ripe vegetables have entered the flowering stage, waiting for the harvest to go to the table~ However, the loofah often has symptoms of burnt flowers during the flowering period, which makes the vegetable farmers worry. What is the solution? Experts come to answer you! Loofah burnt flowers mainly appear dry and rotten, wet rotten, flower head rot and so on. Dry - The edges of the petals appear dry and the entire petals are not fresh. cause This may be caused by blight, which is more severe in low light conditions, especially after cloudy days. treatment method Spraying thiophanate-methyl or Dasheng can be used to reduce the occurrence of diseases. Water rotten - Water rot from the edge of the petals. In severe cases, the petals appear to drip, sometimes smelly, sometimes without white mold. cause The case of odorous but not long hair may be bacterial soft rot, and the white mold may be flower rot or plague, both of which are heavier in high temperature and high humidity. treatment method Bacterial soft rot can be sprayed with streptomycin, neomycin, or can be sprayed with crown bacillus. Flower rot and plague can be sprayed with sera, dextromirer and other agents, or some agents can be added to the anthers of cockroaches. Flower head rot - The stigma of the flower appears black rot, and the flower will also rot. cause This is related to poor absorption of roots or uncoordinated water supply, or it may be caused by lack of elements such as boron and calcium in the soil. treatment method Foliar application of foliar fertilizer containing elements such as boron and calcium, such as Lufenwei No. 3 or No. 2, capped calcium, calcium nitrate, etc., can also be applied to some calcium fertilizer; at the same time, attention must be paid to rooting and strengthening. The absorption capacity of the root system can be increased by applying humic acid or microbial fertilizer, or by mixing certain rooting agents with thiophanate-methyl, carbendazim, ethylphosphonium, aluminum, manganese, and the like. Each plant is about 0.25 kg. Black mold - There are black mildew spots on the flowers. cause Mostly caused by coal mold. treatment method It can be sprayed with thiophanate-methyl 500-fold or 800-fold. According to different methods of use, winches can be divided into four types: manual winches, electric winches, pneumatic winches, and hydraulic winches. At present, the largest marine hydraulic winch is 350T, and the weight of the equipment reaches 150T.

According to the reel form, it is divided into single reel and double reel.
According to the reel distribution, there are parallel double reels and front and rear double reels.
The main technical indicators of hydraulic winches include rated load, supporting load, rope speed, rope capacity, etc.
A winch is a light and small lifting device (see hoisting machinery) that uses a reel to wind a wire rope or chain to lift or tow heavy objects, also known as a hoist. The winch can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large rope winding volume and convenient displacement. The winch is also known as the hoist. The product has high versatility, compact structure, small size, light weight, heavy lifting, and convenient transfer. It is widely used in construction, water conservancy projects, forestry, mines, docks, etc. for material lifting or flat towing, and can also be used as modern electronic control Supporting equipment for automatic operation line.
According to the power, the winch is divided into three categories: manual, electric and hydraulic.
The transmission mechanism of the handle rotation of the manual winch is equipped with a stopper (ratchet wheel and pawl), which can keep the heavy object in the required position. The manual winch used for assembling or lifting heavy objects should also be equipped with safety handles and brakes. Manual winches are generally used in places where the lifting capacity is small, the facilities are poor, or where there is no power supply.
Electric winches are widely used in places with heavy work and large traction requirements. The electric motor of the single-drum electric winch (pictured) drives the drum through the reducer, and a brake is installed between the electric motor and the input shaft of the reducer. In order to meet the needs of lifting, traction and rotation, there are also double-drum and multi-drum winches. Generally, a winch with a rated load lower than 10T can be designed as an electric winch.
The hydraulic winch is mainly a winch with a larger rated load. Generally, the winch from 10T to 5000T is designed as a hydraulic winch. The winch can be divided into:
Marine winches: Marine winches can be divided into drag winches, mooring winches, anchor winches, traction winches, etc.
Engineering winch: Mainly used in engineering, with functions such as hoisting and hoisting as the main function.
Mine winches: divided into hoisting winches, dispatching winches, shaft sinking winches, column return winches, rake mine winches, column return winches, etc.
Cable winch: mainly used when laying cables.
