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.

Red Phoenix vegetable cultivation technology
Hongfeng cuisine is a traditional wild vegetable in China. Its whole grass can be harvested throughout the year, fresh or dried. It is rich in nutrition, has the effect of heat, swelling, hemostasis, and blood. It is popular with consumers. First, biological characteristics. Hongfeng cuisine is aliased as red pandan, red vegetable, red amaranth, red jade dish, red Maofan, and angelica. It is a perennial herb of the Asteraceae family. Mainly distributed in Fujian, Zhejiang, Jiangxi, Guangxi, Jiangsu, Hunan, Hubei and other places, more than 500 meters -1000 meters in the valley of mixed grass, under the forest stream or roadside. 1. Temperature: Hongfeng cuisine prefers a cool and cool climate, requiring a daily average temperature of 15-19°C, a maximum temperature of ≤39°C, and a minimum temperature of ≥-5°C. The daily average temperature of suitable rhizome germination is 8-22°C, and the optimum temperature for the growth of the shoot is a daily average of 20-28°C. Above 30°C, the lignification rate of the stems was accelerated, and the growth rate was slower than 30°C or below 8°C. Stems and roots can be exposed to winter, as long as the temperature is appropriate, can be an annual growth, no significant period of dormancy. Autumn flowering until the spring of the following year. 2. Humidity: In the areas with annual rainfall of 1,300-2,100 mm, Hongfeng can grow. Its roots are tolerant to drought, and it is not easy to die under conditions of high temperature and drought in summer. 3, light: red and green vegetables Xi strong light, if the lack of light grow thin, the annual sunshine hours need 1700-2000 hours. It can also bloom in the shade. The flower buds differentiated in late August, twitching in early September, and flowering in late September until March of the following year. 4. Soil: The requirements of soil are not strict for Hongfeng Cai, yellow soil, sandy soil and red soil can all be planted. Suitable pH is 5.5-6.5. Second, cultivation techniques. The spring planting period is mid-March, and the autumn planting season is from late August to early September. 1. Quality and Treatment of Seed Strains (1) Quality of Seed Strains: Choose robust plants with no pests and diseases, purple-green stalks, and remove top scapes and hybrids. (2) The amount of seedlings used: Spring and autumn Hongfeng dishes: 150 kg per mu planting strain (fresh quality, the same below). Commonly used cutting and layering method. Stem cuttings use 150 kg per acre, and stems hold 200-250 kg per acre. (3) Seedlings treatment: Chunhong Fengcai chooses the thick seedlings to cut flatly, cuts off the soft part of the tip and the aging part of the base, takes the middle stem, cuts the middle part of the growth of 10-13 cm, and cuts the lower part into an oblique mouth. 20 mg/kg naphthylacetic acid soak for 15-30 minutes, or soak for 15-30 minutes with 15-30 mg/kg butyric acid solution. When the autumn red cabbage was planted between August and September, the thick plants were cut flat, and the top tender portion and the base aged portion were cut off. The middle stem was cut into small pieces 10 cm long and put into 20 mg/kg. Soak in butyric acid for 15-20 minutes. 2. Soil preparation and fertilization: Wet, fertile sandy loam is the best. Deep plowing, sunburn, per acre full of cooked pigs, ducks, human fecal urine 2000-3000 kg. Pingyan planting, trampoline sit north and south, 1.5 meters wide, 25-30 cm high, unlimited length. Groove width 30-35 cm. 3. Planting: Chunhong Fengcao is planted with stalk cuttings: The treated plant stems are planted at a spacing of 30 cm or 30 cm or 25 cm and 30 cm, and 3-4 plants per hole are inserted obliquely in the lotus root. on. After planting, the surrounding soil will be compacted and irrigated. Planting 3 to 45,000 plants per acre. Qiu Hong Feng Cai by row spacing 30 cm, 30 cm spacing, 3-4 plants per hole planted, planting 3-45 million per acre. Compaction of the soil and irrigating the water, moisturizing the shade. After 7 days, the shade was removed. 4, field management (1) Spring and Autumn Red Phoenix dishes. Planted in open field and watered every morning after planting to keep the surface moist. During the high temperature and dry period, water should be poured, and drainage will occur in the flood season or after heavy rain. The period from early April to late May is a critical period for growth, with 15 kg of organic compound fertilizer or 5 kg of urea per acre. In August-September, the cuttings are easy to twitch, and the buds must be topped in time before flowering to promote accumulation of nutrients on the stems and leaves. Apply 10 kg compound fertilizer per acre. (2) Protected cultivation: plastic film covering time is from late November to early March. Before the covering, the plants on the ground were cut off, and the 3-5 cm long stem base was left to clear the leaves and dead leaves. 25 kg of organic compound fertilizer is applied per acre, and the temperature is maintained at 15-30°C during the day. If the temperature exceeds 32°C, ventilation is required to reduce the temperature. Stay above 5°C at night and control relative humidity at 65-75%. Generally do not water after buckle plastic film, so as not to reduce the ground temperature to slow growth. After the shoots grow, spray the leaf fertilizer (guarantee microbial leaf synergist). After 3 days of harvesting, 5-6 kilograms of urea were used to water 1000 kilograms of water per acre. 5, harvest. Harvest the shoots as long as 15-20 centimeters. Use a sharp knife to cut 3-5 centimeters from the planter's surface. Pick the leaves and yellow leaves and place them in bales. Dispose of them in vegetable boxes or fresh-keeping bags. After harvesting, clean up the sorghum surface, artificially weeding or using 10.8% of high-efficient gaiseng EC to achieve 30 ml per 1 mu, and 15% of finely stabilized EC to prevent weeds. Harvest in batches, picking 2-3 times water for every 2-3 times, applying 5 kg of urea per acre to promote stalk germination and growth.
