Vertical Magnetic Drill through which the main use of
bit, also is the model we used to say, it carries the biggest drilling core
drill bit, is that the magnetic drill model
A simple introduction Magnetic block drilling and tapping, CVT, torque
protection and can make use of magnetic adsorption force, drilling operations
from different angles. Used with core bit, the effect is better; Also solve the
problem of the pipe to clean waste residue, overlapping drilling can also obtain
satisfactory effect of the steel plate, the stainless steel pipe and a certain
thickness of stainless steel drilling problem can be solved
Have different USES of magnetic drill, is through the link different bit to
realize different functions, magnetic drill bit link types are: 1, auger bit, 2,
core bit 3, countersunk head drill 4, tapping machine, 5, tapping machine 6,
broaching machine
Each type magnetic drill bit 1, the horizontal magnetic drill 2, vertical
magnetic drill Due to magnetic drill in order to adapt to the wild and aerial
work, convenient to carry, the most important characteristic is lightweight, so
horizontal magnetic drill with much customers, the customers to buy the most or
vertical magnetic drill, vertical magnetic drill average of 10 kg, with a
handle, a user only by the handle, file a can into the wild or aerial work, is
very convenient, that is why it is called a portable magnetic drill. Because the
horizontal magnetic drill with very little, so generally speaking of magnetic
drill, is refers to the vertical magnetic drill, i.e. vertical magnetic drill
magnetic drill for short.

At present, asparagus management has entered the stage of spring mother stems, leaving good stems of spring mothers, and cultivating strong mother plants, is the key to the high yield and quality of summer asparagus. The main technical measures for the retention of spring mother stalks are as follows: Proper period of stay: The time for the stay of spring mother stalks should be based on the year of growth of the asparagus. Asparagus growing from bamboo shoots and bamboo shoots for 1-2 years should be maintained around April 25 to the end of the month; spring bamboo shoots should have normal bamboo shoots, and more than 3 years old asparagus should be kept in early May. The number of mothers' stems should be 3-4 for biennial asparagus, 4-6 for 3-year-old asparagus, 5-10 for 4-year-old or more asparagus, and more than enough for large discs. The solid stem with a diameter of 1-1.2 cm is generally reserved for the mother stem. Soil disinfection: Perennial asparagus is generally contaminated with pathogens. This is the source of stem blight and other diseases. Therefore, we must pay attention to soil disinfection. Usually 3-5 days before the stem of the mother, 40% of asparagus green powder 600 times liquid on the disc and the surrounding soil to kill the bacteria in the soil, reduce the number of pathogenic base, protect the breeding mother stem from its invasion. Disease prevention and stem protection: When the retained spring mother's stem grows to 5 cm in height, apply 40% asparagus blue powder 50 times solution to the stem, coat it once every other day, and apply 3-4 times; after the mother stem is branched, Use 40% asparagus blue powder spray 200-300 times, spray once every 2 days, even spray 3-4 times; after putting leaves, spray with 40% asparagus blue powder 400-600 times, the previous interval 3-5 Spray once a day, spraying once every 5-7 days until the end of June spring maturation. Later depending on the growth of the mother stem every 10-15 days before spraying. If it rains after being painted or sprayed, apply it after the rain stops and spray it once. Adding basic fertilizer: spring stems are preserved into plants, and after the shoots begin, organic fertilizers are added in time. Mushroom remnants or maturity bar fertilization 1-1.5 tons, compound fertilizer 5 kg or urea 10 kg, potassium fertilizer 5-7 kg, phosphate fertilizer 5 kg. The top dressing began in late June. In the early stage, it is applied once every 15-20 days, and once every 10-15 days in the later period, 7-8 kg of urea, 5 kg of potassium or 10 kg of compound fertilizer are applied per mu. During the interval between topdressing, using leaf fertilizer such as brassin to spray asparagus leaves at 8-9am or early in the morning can enhance photosynthesis, increase resistance, and increase the amount of shoots. Supporting management: During the middle and late harvest of asparagus, when the rainy season and high temperature and dry season, we must pay attention to flood control and moisturizing. In case of drowning, dredge drainage, remove accumulated water, timely cultivating and weeding after rain, prevent topsoil compaction, timely irrigation of horse water in case of drought, and keeping soil moist to increase yield and quality. At the same time, the fallen yellow stems and some dense stems are often cut off to keep the bamboo gardens ventilated. After the end of August, the number of bamboo shoots was reduced and the stems were yellow. Harvesting should be stopped, and the work of clear gardens should be completed.
