Rape is an important source of rapeseed oil and is also the country's largest source of vegetable oil. During the growth of rapeseed, nitrogen is essential for its growth. Nitrogen deficiency in rape can lead to a reduction in rapeseed production. In the past, due to the lack of scientific detection The method can only apply nitrogen fertilizer based on experience, and the production effect is difficult to guarantee. Now the use of chlorophyll meter to detect the chlorophyll content of rape can help us to meet the demand for nitrogen fertilizer in rape, and then carry out scientific and effective management of nitrogen fertilizer in rape.
Although the chlorophyll content meter mainly determines the chlorophyll content of the plant, not the amount of nitrogen, but because the chlorophyll content is inextricably linked to nitrogen, and nitrogen is a constituent element of chlorophyll, it can also be determined by measuring the chlorophyll content. Whether or not the plant lacks nitrogen, for example, if the chlorophyll content is low, it means that the plant lacks nitrogen fertilizer, and the leaves of the plant are also yellow. This time shows that the plant needs to apply nitrogen fertilizer.
It can also be seen from this aspect that by observing the color of the plant leaves, it is possible to determine whether the plant lacks nitrogen, but the difficulty lies in the inability to determine the amount of nitrogen applied. Now that agricultural production is developing in the direction of refinement, nitrogen fertilizers also need to be precise. Chlorophyll analyzers are used to determine the chlorophyll content of rape plants. It can be determined not only whether the plants need to apply nitrogen fertilizer but also the amount of nitrogen applied. The use of chlorophyll content meter to determine the chlorophyll content of plants is conducive to the rational application of nitrogen fertilizer, improve the nitrogen fertilizer utilization, and can avoid the excessive application of nitrogen fertilizer on soil and water pollution, protect the environment.
Studies have shown that under the scientific guidance of the chlorophyll meter, the management of rapeseed nitrogen fertilizer is more effective and reasonable. It can help to reduce the nitrogen fertilizer use by 10% under the premise of ensuring that the crop yield does not decrease. This is very good for growers. One thing is that both increased production and reduced production costs, and production efficiency has been further improved.

Six Characters of Titanium
|
|
|
1. High Strength
|
Titanium strength/density ratio is better than other metals, components with high strength, good rigity, less weight can be made
out of titanium. Titanium is applied for aircrafts engines, frames, skins, fastners and landing gears. |
|
2. Anti-Corrosion
|
Compared with stainless steel, titanium alloy's corrosion is better in moisture laden air, seawater, titanium greatly resists spot
corrosion, acid corrosion and stress corrosion. Titanium resists corrosions to alkali, chloride, chlorinated organic sunstances, sulphuric acid, nitric acid. |
|
3. High-Temperature Resistance
|
Titanium application temperature's higher than aluminium alloys. Titanium can work in 450-500℃ for long time. Titanium alloy stil
prossesses high strength when working in 150-500℃. Titanium working temperature can be reached to 500℃ |
|
4. Low Temperature Resistance
|
Titanium alloys still owns its mechanical properties when working in low or super low temperature conditions. Titanium alloys with
low-temperature resisitance and extra low interstitial still possess good ductility, therefore, titanium alloy is sort of good low temperature structural material. |
|
5. Eco-Friendly Metal
|
Thermal conductivity of titanium is lower than carbon steel or copper, but titanium owns very good corrosion resistance,
therefore, titanium thickness can be greatly reduced, also the heat exchange mode is dropwise condensation between titanium and steam. This kind of mode reduces heat transfer resistance, no fouling on titanium surface, which makes titanium thermal conductivity better. |
|
6. Good Thermal Conductivity
|
Titanium is non-magnetic metal, it can't be magnetized in large magnetic field, also titanium is toxic-free and compatibility with
blood, there, titanium is applied in medical field. |
