Secondly, angle gauge, left and right sides measuring jaw, index plate etc. have been installed on same rod support, hypsometer has been installed at the back side of scale, thereby reaches the function that a chi is used more.
The present invention has the following advantages:
1, measures accurately: can guarantee seedling grading standard, and be applicable to the classification of variety classes nursery stock, can improve the afforestation quality.
2, this detector amount of possessing footpath and the high function of carrying out simultaneously of amount can be saved the labour, improve work efficiency, and easy to operate, reduce labor strength.
3, can be used for nursery nursery stock output, inspection of quality simultaneously, the afforestation seedling sorting is surveyed sample three aspects in transit.Aspect forest culture and management, can measure diameter at breast height, the height of tree, the basal area of forests at different levels, every mu of strain number, growing stock also can be used for landform six aspects such as gradient conversion in changing.
4, this detector can be stretched and can contract, and each accessory can load and unload as required, uses flexible, easy to carry.Desire to enter the multinomial factor of forest region survey, use this detector to finish, can overcome and entered the inconvenience that multiple detection utensil need be carried in the forest zone in the past.
