the invention relates to an auxiliary tool for standard manufacture of a field test plot, which comprises four vertex angle parts with positioning holes and six calibration inelastic ropes which are connected with the vertex angle parts into a square or a rectangle and are respectively provided with four sides and two diagonals; the actual length setting of the six inelastic ropes is carried out according to the size of the cell set by actual needs and whether the operation of personnel is convenient or not.

Furthermore, the four corner ejecting parts with the positioning holes are arranged to be capable of stretching, contracting and contracting the device with the scale inelastic rope towards two direction ends and a middle diagonal end which are at right angles, and have a telescopic locking function.

Furthermore, above-mentioned apex angle part is including being square shape's box body, is equipped with the through-hole that pierces through the box body upper and lower face also and is the locating hole at a apex angle position of box body, is equipped with the tape measure pivot respectively in the box body that belongs to other three apex angle position in the box body, and no elastic rope coils in the tape measure pivot, and no elastic rope marks clear scale on, and near tape measure opening sets the press key that carries out flexible locking to no elastic rope, corresponds respectively and sets up on the box body lateral wall.

The use principle of the invention is as follows: the invention uses 6 inelastic ropes to make two pairs of parallel sides with equal length and a pair of diagonal lines with equal length, when the 6 ropes are in a stretching state, the figure formed is rectangle (or square), at this time, four points determined according to the positioning holes can directly determine the rectangle (or square) formed by all the cells, or the four points determine the rectangle (or square) formed by all the cells by using the principle of 'three points and one line'; a slack condition in any of the cords indicates a non-rectangular (or square) shape.

The invention has the beneficial effects that:

in field planting experiments, a large number of plot making is needed. The district is the rectangle or the square of settlement area generally, and big field piece is many irregular, and or many field pieces often all have length or width of several hundred meters, and when making a plurality of districts of experiment, present equipment tool generally all is that the people come the operation to hardly can guarantee the district of making to keep standard square or rectangle all the time, just can not do all the time and keep the straight line, especially is difficult to accomplish when the district length reaches several hundred meters.

And if the laser range finder commonly used in the building field is adopted, the following disadvantages exist: 1. the existing laser range finders measure straight lines, if the straight lines need to be measured and adjacent straight lines need to be ensured to be in accurate right angles, at least two laser range finders need to be matched, two range lasers are corrected to be in right angles in advance, and a matched accessory structure and the like used by matching the two laser range finders need to be additionally and independently designed, so that the cost is high, and the structure is clumsy; 2. in the actual plot production, for the field plot with the movement length exceeding several hundred meters, the common laser distance measuring instrument is adopted not far, but the more professional and higher laser distance measuring instrument is adopted, so the cost is higher undoubtedly, and the laser distance measuring instrument is not suitable for being used in the field test. 3. Furthermore, for plot making in field planting experiments, the accuracy of the laser rangefinder is not necessary at all.

The invention is made by using a lighter inelastic rope, the top corner adding part is also quite light, the manufacturing cost is very low, the integral structure is simple and ingenious, the usability is very simple, but the measurement accuracy is very high, the invention is very suitable for being carried and used in field operation, and the invention can be adjusted into rectangles or squares with different sizes according to the requirement and has two diagonal lines with equal length. The invention can quickly and accurately determine the four sides of the test cell manufacturing land, so that the four sides form a rectangle or a square, and then a single cell is manufactured according to the design, thereby realizing the quick, standard and standard manufacturing of the cell.

The invention fills the blank of the product at home and abroad, and has great application potential in agricultural scientific research.
