A few days ago, the Dianchi Lake Basin 50,000 mu of straw returned to the field to control agricultural non-point source pollution demonstration and promotion projects were accepted by the expert group. Since last year, Kunming City Lianchi Administration has completed 50,379 acres of demonstration area in 4 lakes and counties, and 56,000 tons of straw has been returned directly to fertilization, reducing the amount of phosphorus, nitrogen and potassium emissions by nearly 400 tons. At the same time, the direct return of straw to the field also reduces the amount of chemical fertilizers used, and improves the quality of vegetables and flowers.
According to experts, at present, Dianchi Lake Basin produces large amounts of farmland waste such as straw and vegetables every day. Without treatment, these nitrogen, phosphorus, and potassium contents are higher than those of cow dung, causing pollution to Dianchi Lake. In order to effectively control the pollution of farmland solid wastes and excessive use of chemical fertilizers and pesticides on the water in Dianchi Lake, the problem of increasingly serious agricultural non-point source pollution has been solved at the source. Since last year, four Kunyu hurricanes have been introduced successively along the lakes and counties. The company independently developed Hurricane No. 1 straw directly to the biotechnology. The direct return of straw from the Hurricane I biotechnology involves the collection and mashing of fresh waste straw, spraying on field fertilizers, and burying it in the field to treat agricultural waste in situ and return it to the field to act as a base fertilizer for the crop, so that the waste straw becomes Organic Fertilizer.
Experts believe that this biotechnology has achieved the goal of preventing agricultural straw pollution, reducing soil nutrient loss, and reducing the use of fertilizers and pesticides. It is both a technological breakthrough for straw returning to fertilizer and an important measure for gradually controlling Dianchi agricultural agricultural non-point source pollution. Experts recommend that more efforts be made to promote the use of the technology in the Dianchi Lake Basin, especially the facilities around the lake.
Gantry Type Video Measuring Machine
The gantry-type Video Measuring Machine can efficiently detect the contours, surface shapes, dimensions, angles, and positions of various workpieces. It is mainly used to measure the size and angle of parts and components that are difficult or impossible to measure with a caliper and angle ruler but play an important role in assembly. It can also be used to take pictures of some parts and components to analyze the causes of defects, especially for PCB boards, films, protective films, optical glass, electronics, large sheet metal parts, connectors, precision mechanical parts, electronic components, semiconductor components, and other industries, It can achieve rapid and accurate detection in large quantities.
advantage:
1. Adopting a high-power industrial high-definition color CCD and a continuous automatic zoom depth lens with fixed frame position, the zoom rate does not require calibration, greatly improving work efficiency and measurement accuracy.
2. Images can be output to electronic computer software for surveying and mapping engineering storage. It can be used for photography, copying, and storage.
3. It can inspect the specifications of buried holes, pipe trenches, etc. on the upper surface of the tested object block. The image and color tone on the surface of the product workpiece can be clearly seen.
