A field wheat stem tillering number extraction method, including: acquiring field wheat point clouds by means of a LiDAR, and extracting any row of wheat point clouds in a research area; projecting a Y axis to a plane, and retaining an X and Z axis; applying adaptive layering to obtain number of clusters of the wheat row; applying hierarchical clustering analysis to obtain tillering number of each wheat cluster; and further obtaining stem tillering number of the whole wheat row, so as to extract a field wheat stem tillering number. The feasibility of an algorithm is verified by comparing the wheat stem tillering number extracted by means of the method with an actually measured field stem tillering number, and the method realizes rapid, accurate and nondestructive extraction of a large-field crop stem tillering number and provides theoretical basis and technical support for extraction of the field wheat stem tillering number.

Disclosed is a design method for a three-dimensional special-shaped jet nozzle used in the field of water-saving irrigation in farmland. According to a method based on a gas-liquid two-phase flow theory and computational fluid dynamics (CFD), a fan-shaped jet mode and a beam-shaped jet mode are coupled according to a certain area ratio and velocity ratio, which enables a cylindrical-conical coupling structure to be presented all the way from an inlet to an outlet of the nozzle, and a jet orifice is optimally designed into a three-dimensional special-shaped slotted structure; along a flowing direction of the jet orifice, V-shaped slots are formed in bottom and front portions of a midperpendicular plane, where a fan-shaped jet capable of forming a near-range water body prevails, and a strip-shaped slot is formed in an upper half portion of the midperpendicular plane, where a beam-shaped jet capable of forming a far-range water body prevails; and the V-shaped slots and the strip-shaped slot promote the formation of a narrow-band range S in a synergistic manner due to smooth joint transition therebetween. The present disclosure is particularly suitable for farmland sprinkling irrigation operations in non-planted areas such as tractor roads and field roads, and has the unique advantages of saving water and energy, and not rolling soil and crop seedlings.
