Plant chlorophyll, nitrogen content and moisture content are important nutrition and .They’re important basis for plant fertilization and irrigation.

Use near infrared spectroscopy ,test leaf chlorophyll, nitrogen and moisture content by near-infrared spectrum nondestructive testing.Can nondestructive test three plant nutrition and growth physiology information .

Introduction:
1.Save three s (chlorophyll, nitrogen and moisture content) at the same time, easy to draw plant nutrient ,moisture and so on information graph .Provide for plant precision irrigation and fertilization.

2. Nondestructive test plant quickly , not to effect plant growth.

3. s rapid determination :Test  plant chlorophyll, nitrogen and moisture at the same time.

4. Test point location information:Receive by inner GPS module , NAME-83 license agreement and Serial Port Break.The received data decode to longitude, latitude, speed, time, (clock and calendar,year,month, day ,hour,minute and second) and so on . and store these informations . Time can be set manually

5. Have Automatic and Manual measurement pattern

6. View past stored data,show three parameters at the same time .

7. The computer can transfer wired or wireless data so as to manage and analyse  

8. show results.Clear and have backlight function.
9.Easy to store data ,directly show stored data .

10. and show low power consumption.
