The relationship between chlorophyll and yield of sesame and the changing rules of different growth periods

The relationship between chlorophyll and yield of sesame and the changing rules of different growth periods Sesame is one of the important oil crops in China, and it is also a traditional export-oriented crop, which occupies a very important position in the adjustment of crop structure. To obtain high yields of sesame, it must be ensured that the “source” is large, and this so-called “source” refers to the amount of photosynthesis products. It is a feasible way to increase production by accumulating more photosynthetic products per unit time. Photosynthesis of plants is done in the chloroplast and the chlorophyll content is closely related to the photosynthetic rate of the leaves. The sesame seeds are hi-light crops, and the leaves are the main organs for photosynthesis of sesame. Therefore, it is helpful to understand the relationship between chlorophyll content and sesame yield for the measurement of chlorophyll content in sesame leaves. The chlorophyll measurement method can use the chlorophyll meter for rapid measurement and analysis.
Using the SPAD502 chlorophyll meter to measure the chlorophyll content of nearly one hundred sesame seeds, the relationship between chlorophyll content and yield was analyzed. It was found through analysis and comparison that the chlorophyll content was positively correlated with the yield per plant, but it was not significant. , indicating that increasing the chlorophyll content has a certain direct effect on the yield increase; the chlorophyll content is significantly or extremely significantly positively correlated with plant height, fruit stem axis length and 1000-grain weight in the yield component factors, indicating that increasing the chlorophyll content is mainly through increasing the plant height. The length of the stem of the main stem and the indirect effect of increasing the weight of one thousand grains are used to increase the yield. In the further analysis and understanding of the sesame seeds that have been found to have a relatively high chlorophyll content during the planting process, it is very helpful for increasing sesame yield.
Chlorophyll meter was used to analyze the chlorophyll content of sesame at different stages. Chlorophyll content was different at different developmental stages, was lower at the early flowering stage, then gradually increased, and reached the highest at the final flowering stage. The chlorophyll change pattern is consistent with that of rice, wheat, and other grains.

In order to ensure that the surface of the pulled steel wire is clean and powder-free, a cleaning equipment device is used for cleaning treatment. An appropriate (usually 1%) metal surface treatment agent is added to tap water, and the surface of the steel wire is washed by a high-pressure submerged pump (1.1KW). At the same time, a cleaning ball is used to wipe the surface of the steel wire in the passage. In order to ensure that the surface of the steel wire is wrapped without water before entering the winding line, So, at the outlet of the steel wire, a high-pressure air blowing device is used to vigorously blow the steel wire surface 360 ° without gaps, ensuring that there is no water vapor in the steel wire during winding. This cleaning machine is divided into two layers: upper and lower, with a steel wire passage layer on top. The specification is 400X300X2000, which is made of stainless steel welded material. Inside, there are nine adjustable cone wiping devices, which tightly contact the steel wire and the cleaning ball for wiping; The lower layer is a water storage tank, with a specification of 800X700X1600, which is welded from 4mm stainless steel plate. There is a filtering area in the water tank, and the filtered water is pumped out from the anti-corrosion liquid pump on the water storage tank into the upper aisle water tank for flushing. The underwater pump will not block and has a longer lifespan. The lower water tank is equipped with a decontamination hole to remove debris and garbage. According to customer needs, in areas where the weather is too cold, an electric heating system or a steam heating system can be installed on the water tank, and the heating temperature can be designed to maintain a certain temperature for flushing and wiping with water.
