experiment example 1
[0113] Statistical embodiment 1, embodiment 2 and the average fresh product output, average dry product output, volatile oil content, curedione content and β-elemene content of the warm curcuma seeds that method described in comparative example 1 obtains, wherein, volatile oil content, Curcumadione content and β-elemene content are the results detected in 100g samples randomly selected from three examples.
[0114] The statistical results are shown in Table 1:
[0115] Obtain the quality of Wenyujin in Table 1 embodiment 1, embodiment 2 and comparative example 1
[0116]
[0117] As can be seen from Table 1, the method for warm turmeric cultivation described in embodiment 1 and embodiment 2 is compared with the traditional cultivation method of comparative example 1, its average fresh product yield, average dry product yield, volatile oil content, curedione content and β-elemi Alkene content has been significantly increased.
[0118] Wherein, the average fresh product out...
