Abstract
A photosynthetic rate measuring device for an entire plant belongs to agriculture detecting instruments, wherein, a seal tank is arranged on the upper side of a seal base; a light transmitting sealedbox body is inserted in the seal tank; an air inlet pipe and an air outlet pipe are relatively assembled on the side wall of the light transmitting sealed box body; a drier, an air pump and a gas tester are sequentially assembled on the air outlet pipe; and two power fan assemblies are respectively arranged at the side bottom and the side top on the relative walls of the light transmitting sealedbox body. The photosynthetic rate measuring device can be used for measuring the photosynthetic rate of an entire potting plant, and is characterized by reasonable structural design, low cost, simpleoperation, convenient use and maintenance, reliable operation and accurate measurement.
Description
Technical field
The utility model belongs to agriculture detecting instrument, relates generally to the device that the whole strain photosynthetic rate of a kind of potted plant crop is measured.
Background technology
So-called photosynthetic rate just is meant the photosynthetic part after the carbon dioxide absorption amount of unit are blade in the unit interval removed breathing.Plant utilizes luminous energy CO by photosynthesis
2And H
2O assimilate into organic matter, and discharge O
2Research photosynthesis, to improving crop yield, the protection environment is all significant.Mostly currently used photosynthetic determinator is to measure the photosynthetic rate of individual blade, and a lot of requirement of experiment are carried out under condition of pot, measure the photosynthetic rate of whole strain plant, and the photosynthetic rate that needs a plant different times of replication, based on such requirement, just need find the credible determinator easily of a cover.For standard more, measure the photosynthetic rate of the whole strain of crop more accurately,, be necessary to research and develop the whole strain photosynthetic rate determinator of a kind of potted plant crop to reduce the influence that the land for growing field crops complex environment is measured photosynthetic rate.
Summary of the invention
The purpose of this utility model is exactly at photosynthetic characteristics, overcoming existing land for growing field crops photosynthetic rate determinator is problem and the defective that determination object exists with the individual blade only, design the whole strain photosynthetic rate determinator of a kind of potted plant crop, guaranteeing to measure accurately simultaneously, make to measure and become more convenient, and potted plant sample is reusable, much experimentally more suitable.
Basic design of the present utility model is, is provided with water sealed tank on sealed base upper lateral part outside wall surface periphery or internal face periphery, and the inserting of illumination printing opacity closed box is installed on the water sealed tank; Air inlet pipe is relative with escape pipe to be fitted on the illumination printing opacity closed box sidewall, and drier, air pump and apparatus for determination of gas are installed on escape pipe from the inside to the outside successively.At two power fan assemblies of the inner installation of illumination printing opacity closed box, two power fan assemblies lay respectively at the relative wall's side lower part and the upper lateral part position of illumination printing opacity closed box, so far constitute the whole strain photosynthetic rate determinator of crop.
The utility model can be applied to the photosynthetic rate of the whole potted plant crop of strain and measure, make measure save time, laborsaving, accurate, have structural design novelty, simple to operate, with low cost, operation and maintenance characteristics easily.

Accompanying drawing is the whole strain photosynthetic rate determinator general structure schematic diagram of crop.
Piece number explanation among the figure:
1, air inlet pipe, 2, power fan assembly, 3, escape pipe, 4, drier, 5, air pump, 6, apparatus for determination of gas, 7, illumination printing opacity closed box, 8, water sealed tank, 9, sealed base.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the utility model is described in detail.A kind of crop is put in order strain photosynthetic rate determinator, is provided with water sealed tank 8 on sealed base 9 upper lateral part outside wall surface peripheries or internal face periphery, and 7 insertings of illumination printing opacity closed box are installed on the water sealed tank 8; Air inlet pipe 1 and escape pipe 3 relative being fitted on illumination printing opacity closed box 7 sidewalls are installed drier 4, air pump 5 and apparatus for determination of gas 6 from the inside to the outside successively on escape pipe 3.Lay respectively at the relative wall's side lower part and the upper lateral part position of illumination printing opacity closed box 7 at 2, two power fan assemblies 2 of illumination printing opacity closed box 7 inner two power fan assemblies of installation.
When operation is used, the whole strain of potted plant crop is positioned in the sealed base 9, water filling in water sealed tank 8 to intercept gas and the ambient atmosphere exchange gas in illumination printing opacity closed box 7 and the sealed base 9, guarantees quality measurement; Close air inlet pipe 1, utilize the power fan assembly 2 of two configurations that misplace relatively that the gases in casing 7 and the base 9 are mixed, start drier 4, air pump 5 and apparatus for determination of gas 6, gases in casing 7 and the base 9 after escape pipe 3 enters drier 4 and carries out drying, are entered apparatus for determination of gas 6 by air pump 5 and finish whole strain crop photosynthesis rate determination work.
