Embodiment

[0020] The embodiment of the present invention provides a kind of method of forecasting cowpea yield, and this method comprises:

[0021] Provide the blade of the cowpea plant to be detected;

[0022] Obtain leaf temperature, actual photosynthetic efficiency Y(II), photochemical quenching coefficient qL, non-photochemical quenching coefficient NPQ, non-regulated energy dissipation quantum yield Y(NO), maximum photochemical quantum yield Fv / Fm, transpiration rate , leaf stomatal air conductance, chlorophyll a content and pod shedding rate.

[0023] Substitute into the formula D=6553.22+227.73X 1 +3734.57X 2 -3428.93X 3 -4128.39X 4 -8822.36X 5 -13995.19X 6 +6.86X 7 -29.92X 8 +56.68X 9 -11.50X 10 , calculate the output forecast value D. where X 1 is the temperature of the leaves, and temperature is one of the main factors affecting photosynthesis, and the temperature of the leaves is too high or too low to have a certain inhibitory effect on the photosynthesis of plan...

Abstract

The invention discloses a method for predicting yield of cowpea, belonging to the field of biotechnology. The method comprises the following steps: providing leaves of to-be-detected cowpea plants; obtaining the temperature, actual photosynthetic efficiency Y (II), a photochemistry quenching coefficient qL, non-photochemistry quenching coefficient NPQ, non-accommodative energy dissipation quantum yield Y (NO), a maximum photochemistry quantum yield Fv / Fm, a transpiration rate, air conduction degree of air holes of the leaves, the content of chlorophyll a and flower and pod adscission rate of the leaves; substituting the obtained values into a formula 6553.22+227.73X1+3734.57X2-3428.93X3-4128.39X4-8822.36X5-13995.19X6+6.86X7-29.92X8+56.68X9-11.50X10 so as to calculate a yield predicting value D. Compared with an actually observed yield result, the yield result obtained by the method for predicting yield of cowpea is low in error; the yield of the cowpea can be accurately predicted; the yield of the cowpea can be predicted in a cowpea squaring period; the detection period is shortened.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for predicting cowpea yield. Background technique [0002] Cowpea is one of the important summer legume vegetables in my country. It is loved by producers and consumers because of its wide adaptability, good quality and stable economic benefits. [0003] The existing methods for identifying the yield of cowpea can analyze the factors affecting the yield through stepwise regression, and the independent variable parameters selected are mostly the organ weight of cowpea at the harvest period, such as the weight of a single pod at the harvest period, the single leaf weight at the harvest period, etc. Weight, etc., such an identification method needs to wait until the harvest period of cowpea, which makes the period of identifying cowpea output longer. Contents of the invention [0004] In order to solve the problem in the prior art that it takes a long period to identify the ...
