Strawberry in the growth process, the reasonable application of nitrogen fertilizer, can play a role in increasing production and income, but in recent years in strawberry cultivation found that with the continued heavy use of nitrogen fertilizer, nitrogen fertilizer production decreased significantly, while the use of low nitrogen fertilizer utilization It also caused a series of problems such as the deterioration of the ecological conditions in the field and groundwater pollution. In order to solve this problem and realize the efficient use of nitrogen fertilizer, in the current strawberry planting, we can use the chlorophyll meter to diagnose the nitrogen nutrition of strawberry, and provide an important basis for scientific fertilization. The application of chlorophyll meter in the diagnosis of strawberry nitrogen nutrition provides important ideas and technical support for the diagnosis of topdressing strawberry, and has strong practicality and feasibility. In the actual production process, we can use chlorophyll meter to determine the chlorophyll content of strawberry plants, and then detect the plant nitrogen content, understand the crop's nutritional status, thus providing a theoretical basis for the diagnosis of nitrogen and nitrogen application of strawberry. Although the SPAD value measured by chlorophyll meter is the external performance of strawberry nitrogen status, in the measurement study, we can see that the SPAD value measured by chlorophyll meter and soil inorganic nitrogen, plant total nitrogen and leaf nitrate There is a significant linear correlation between the contents, which indicates that, to a certain extent, the SPAD value can reflect the relative contents of soil inorganic nitrogen, plant total nitrogen, and leaf nitrate, so the chlorophyll meter determination data can be used as nitrogen An important indicator of nutritional diagnosis. How much nitrogen fertilizer is needed in the production process of strawberry is determined by its nitrogen nutrition status and the actual application of nitrogen in the soil. It is not that the more the application, the better. Using the chlorophyll meter to diagnose the nitrogen status of strawberry can help us understand the nutritional status of the strawberry plant and the nitrogen content in the soil, and then carry out the scientific fertilization operation. This will not only reduce the cost of applying nitrogen fertilizer, but also improve the strawberry plant. The utilization rate of nitrogen fertilizer, at the same time improve the yield of strawberry cultivation, optimize the growth environment for strawberry cultivation, further increase the added value of strawberry products, and at the same time have important significance for the development of green organic strawberry cultivation industry.

Spots recommended
A.Express way:edge line of the express way ,diversion line,decelerating line near the toll booth and turns in the road.
B.Edge line of the city road,double amber line,cross road,sharp turn,entrance and exit of ramp,
decelerating line in front of the gates of schools,enterprises and institutions.
C.National,provincial and county roads:continuous declivity slope section,sharp turn preparation section,decelerating line before prevarication road,edge line and single amber line in all sections.
Features of fixing
Compulsory deceleration,reminding by shakes,glistening in rainy days and anti-slippery
1.Compulsory deceleration:remind the driver to slow down in dangerous section such as turn and slopes;
2.Reminding by shakes:Remind and warn the diver who drivers in fatigue or absent-mindedly;
3.Glistening in rainy days:Mark driving safe with clearer visual.
4.Anti-slippery:Magnify the friction with road and slow down the vehicle.
Major functions
When the driver is driving in fatigue or absent –mind-eely,the car shakes when it passes over the prominent lines giving out harsh noise.As a result,the driver comes back to sense promptly and readjusts the direction of the car thus preventing accidents.The prominent lines have better tree-dimensional reflection of light so that the driver can tell the direction and lane in rainy days.The mark lines guarantee the security of driver and provide compulsory deceleration and anti-slip-pery.
