3. experimental design: repeating three times.

4. August 7 is sowed, such as field management weeding, intertillage, watering are consistent for other.

(4) test result:

Growth period observation: the emergence of application 5 product of embodiment is neatly healthy and strong, and growing way is preferable, applies the life of 5 product of reference examples It is long normal.

Yield comparison: the Chinese cabbage 667m of 5 product of embodiment is used²Producing is 6512kg, applies 5 product of reference examples than control (6128kg/667m²) increase production 384kg, rate of growth reaches 6.27%.

Disease survey, the diseased plant rate for applying 5 product of embodiment is extremely low, only accounts for 0.02%, and do not have grave illness strain, than control The diseased plant rate for applying 5 product of reference examples reduces 8.12%.

The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered It is considered as protection scope of the present invention.
