Abstract

The invention discloses a living body measurement method and device of thickness of a rice leaf. The method comprises the following steps of: selecting the growing rice leaf as a measuring object; measuring the fixed position of the rice leaf by using a special leaf thickness measuring device; placing the fixed position of the leaf between a rice leaf contact plate and a base of the leaf thickness measuring device and keeping the fixed position away from the main vein of the leaf rice; when the full-leaf thickness of the fully spread rice leave is measured, measuring leaf tip, middle and base, wherein the base measuring point of the rice leaf is at 2 / 3 of the full leaf length; and averaging the measured leaf thickness data of three points, wherein the obtained average value is the thickness value of the full leaf. The method can directly measure the thickness of the living body rice leaf so as to improve the efficiency, simplify the operation, reduce the cost and improve the accuracy; and the method can perform living body measurement to the rice leaf thickness in the field so as to eliminate the sampling steps, implement the continuous tracking to the sample and eliminate the complex process of the data statistic analysis of the destructive sampling experimental data.

Description

technical field

[0001] The invention relates to a method and equipment for the thickness of plant leaves, in particular to a method for measuring the thickness of rice leaves in a living body and a measuring device thereof. Background technique

[0002] The thickness of rice leaves has always been valued by the rice farming community. Around the 1960s, Japanese rice growers Matsushima and Kakuda proposed that leaf thickness be used as an indicator of rice fertility tolerance, and that high-yield rice should have thicker leaves. , their view is still in use today. Recently, rice scholars believe that leaf thickness is one of the five basic factors of rice leaf shape, and it is an important selection index in breeding and an effective diagnostic index in high-yield cultivation, and further pointed out that leaf thickness is an important leaf state factor that cannot be replaced by other factors. . Yuan Longping further pointed out that the thick and straight flag leaves of s...
