Problems solved by technology

[0002] There are tens of thousands of seeds in a single capsule of orchids and they are as light as dust. To measure the weight of a single seed of orchids, a high-precision instrument (such as: one hundred thousandth analytical balance) is usually used. This method is accurate High precision, but the price of one hundred thousandth analytical balance is high, which is difficult for most ordinary laboratories or factories; in addition, if the seeds are delivered to a special factory for measurement, the production cost will be increased. In order to ensure the measurement Under the premise of the accuracy of the results, solve the problems of high cost and long cycle of the existing measurement methods

Embodiment 1

[0040] a. Material

[0041] Use mature gastrodia elata seeds preserved in 2020.

[0042] b. Weighing instrument test and seed weighing

[0043] Before using the ten-thousandth balance, test the accuracy, precision, and sensitivity of the balance; cut the tin foil into a square before weighing, and fold the tin foil along the diagonal in advance for easy weighing and folding storage. Weigh three times (A. 0.0108mg, B.0.0128mg, C.0.0138mg), after weighing, use tweezers to take out the tin foil, and fold the marks according to the folding marks.

[0044] c. Error test of configuring sodium hypochlorite solution and measuring tool

[0045]It has been tested that one-tenth of the sodium hypochlorite solution helps the seeds to sink quickly. Pour the three groups of seeds A, B, and C into three bottles of 50ml sodium hypochlorite solution respectively, and wait for the seeds to sink completely. During this period, make a measuring tool, cut the 10ml centrifuge tube and make it i...

Embodiment 2

[0049] a. Material

[0050] The mature white and seeds preserved in 2019 are used.

[0051] b. Weighing instrument test and seed weighing

[0052] Before using the ten-thousandth balance, test the accuracy, precision, and sensitivity of the balance; cut the tin foil into a square before weighing, and fold the tin foil along the diagonal in advance for easy weighing and folding storage. Weigh three times (1.0. 0115mg, 2.0.0125mg, 3.0.0120mg), after weighing, use tweezers to take out the tin foil, and fold the marks according to the folding marks.

[0053] c. Error test of configuring sodium hypochlorite solution and measuring tool

[0054] It has been tested that one-tenth of the sodium hypochlorite solution helps the seeds to sink quickly. Pour the seeds of groups 1, 2, and 3 into three bottles of 50ml sodium hypochlorite solution, and let them stand until all the seeds are submerged in water. During this period, make a measuring tool, cut the 10ml centrifuge tube and make...

Abstract

The invention relates to a method for measuring weight of orchid seeds, and aims to solve the problem that a mode of determining the weight of orchid seeds cannot be widely applied to common factories or laboratories due to a high price of precise instruments which are used for measuring the weight of orchid seeds at present. The method aims to solve the problem that the weight of orchid seeds is difficult to measure under the condition of no precise instrument. The method mainly comprises the following four steps: weighing by using a one-ten-thousandth balance, uniformly sinking seeds, weighing suspension by using a device, and counting the weight of a single seed. The one-ten-thousandth balance and a metering device (10ml centrifugal tube is cut into a 1ml spoon) used in the method are low in value and easy to manufacture, and when the method is used for measuring the weight of the orchid seeds, time and cost are greatly saved, and accuracy is high.

Description

technical field [0001] The invention relates to the field of plant science, in particular to a method for measuring the weight of orchid seeds. Background technique [0002] There are tens of thousands of seeds in a single capsule of orchids and they are as light as dust. To measure the weight of a single seed of orchids, a high-precision instrument (such as: one hundred thousandth analytical balance) is usually used.
