Key points of high-yield cultivation techniques for autumn cabbage
As the saying goes: the first radish of the radish mustard the autumn cabbage. At present, the season for planting autumn cabbage has been introduced. The main points of cultivation techniques are as follows:
First, choose the variety. Generally, the land with good fertilizer and water conditions is high, late and medium mature; the land with poor fertilizer and water conditions is short and early mature.
Second, fertilization and land preparation. Each mu of high-quality farmyard manure 5000 kg diammonium 20 kg or superphosphate 50 kg potassium sulfate 25 kg or ternary compound fertilizer 30 kg. The ridge width is 30 cm and the width is 30 cm high and 15 cm high.
Third, the appropriate sowing. The sowing period of autumn cabbage is generally 1-2 days before and after the “Liuqiuâ€, around August 8th, on the ridge, the planting distance is 35 cm (the live broadcast does not need to slow down the seedlings).
Fourth, field management. Seedling management
After sowing, watering the water and fixing the seedlings, and then pouring water in a timely manner after watering or timely cultivating after rain. In the rosette period, 1000 kg of manure and 10 kg of urea are applied. During the ball-forming period, the manure 2000 kg or urea 15 kg should be poured every 5-6 days. The water should be stopped 8 days before harvesting to avoid the rot of the ball due to excessive moisture.
Fifth, the prevention of pests and diseases. Prevention and treatment of "three major diseases": using virus No. 1 oil emulsion 500 times liquid to control viral diseases; using 40% ethyl phosphate aluminum 300 times liquid to control downy mildew; using 150ppm agricultural streptomycin sulfate to control soft rot; using 90% Trichlorfon 100 times liquid to prevent jumper; use domestic 50% anti-Poly 2000 times liquid to control aphids; use BT emulsion to control cabbage caterpillars.
A hydraulic fastening tool is a type of power tool that uses hydraulic pressure to quickly and efficiently fasten or loosen nuts, bolts, and other fasteners. It is commonly used in industries such as construction, automotive, and manufacturing.
The tool consists of a Hydraulic Pump that generates pressure, a Hydraulic Hose or line to transmit the pressure, and a hydraulic cylinder or motor that applies the pressure to the fastener. The tool may also have various attachments or sockets to fit different sizes and types of fasteners.
Hydraulic fastening tools are known for their high torque output, allowing them to handle heavy-duty fastening applications. They are often used in situations where manual or electric tools are not sufficient, such as when dealing with rusted or stubborn fasteners.
Some advantages of hydraulic fastening tools include:
1. Speed and efficiency: Hydraulic tools can quickly apply high torque, reducing the time and effort required for fastening or loosening tasks.
2. High torque output: Hydraulic tools have a high torque output, making them suitable for heavy-duty applications that require a lot of force.
3. Versatility: Hydraulic fastening tools can be used with various attachments and sockets, allowing them to handle different sizes and types of fasteners.
4. Portability: Many hydraulic fastening tools are compact and lightweight, making them easy to transport and use in different locations.
5. Durability: Hydraulic tools are typically built to withstand heavy use and harsh working conditions, ensuring long-lasting performance.
Overall, hydraulic fastening tools are a reliable and efficient option for professionals who need to quickly and securely fasten or loosen nuts, bolts, and other fasteners.
