Examples
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...
