Summary of the invention:
First object of the present invention is to provide the application of blackspiked lovegrass herb with root in the feed addictive in preparation shortening black soldier flies larval growth cycle.
The present invention is proved by test, after adding dew grass meal, can shorten black soldier flies breeding cycle 0.5-3 days in black soldier flies larvae feeds.
Therefore, blackspiked lovegrass herb with root can shorten the application in the feed addictive in black soldier flies larval growth cycle in preparation.
Second object of the present invention is to provide a kind of feed that can shorten the black soldier flies larval growth cycle, it is characterized in that, comprises conventional black soldier flies larvae feeds and dew grass meal, and the dosage of described dew grass meal is 1 ~ 10% of conventional black soldier flies larvae feeds quality.
Preferably, the particle diameter of described dew grass meal is between 10 μm ~ 500 μm.
The present invention adds dew grass meal in conventional black soldier flies larvae feeds, and then black soldier flies larva of feeding, and can shorten black soldier flies breeding cycle 0.3 ~ 3 day, substantially increase cultivation efficiency, have broad application prospects.
Detailed description of the invention:
Inventor is by a large amount of test for a long time, and after finding to add dew grass meal in black soldier flies larvae feeds, black soldier flies larva can shorten black soldier flies breeding cycle.
In order to better understand essence of an invention, below in conjunction with example, technology contents of the present invention is described in detail, but content of the present invention is not limited to so, therefore can not be interpreted as the restriction to the scope of the claims of the present invention.
Embodiment 1:
The blackspiked lovegrass herb with root of fresh collection is air-dry under field conditions (factors), utilize superfine communication technique, blackspiked lovegrass herb with root is crushed to 10 μm, obtain dew grass meal.Take black soldier flies larvae feeds peanut press pulp 10kg, 10 μm of dew grass meal 0.1kg, obtain the feed that can shorten the black soldier flies larval growth cycle after mixing thoroughly, for subsequent use, add water appropriate during each use.After egg hatching 1 day starts to add the forage feed that can shorten the black soldier flies larval growth cycle, reinforced to stopping during prepupa, feeds black soldier flies larva in contrast with the black soldier flies larvae feeds peanut press pulp not adding dew grass meal.In experimentation, the growth cycle of the black soldier flies larva that the feed having added the shortening black soldier flies larval growth cycle of dew grass meal is fed shortens 0.5 day compared to control group.
Embodiment 2
Take black soldier flies larvae feeds peanut press pulp 10kg, particle diameter 10 μm of dew grass meal 1kg, obtain the feed that can shorten the black soldier flies larval growth cycle after mixing thoroughly, for subsequent use, add water appropriate during each use.After egg hatching 1 day starts to add the forage feed that can shorten the black soldier flies larval growth cycle, reinforced to stopping during prepupa, feeds black soldier flies larva in contrast with the black soldier flies larvae feeds peanut press pulp not adding dew grass meal.In experimentation, the growth cycle of the black soldier flies larva that the feed having added the shortening black soldier flies larval growth cycle of dew grass meal is fed shortens 3 days compared to control group.
Embodiment 3
Take black soldier flies larvae feeds peanut press pulp 10kg, particle diameter 100 μm of dew grass meal 0.5kg, obtain the feed that can shorten the black soldier flies larval growth cycle after mixing thoroughly, for subsequent use, add water appropriate during each use.After egg hatching 1 day starts to add the forage feed that can shorten the black soldier flies larval growth cycle, reinforced to stopping during prepupa, feeds black soldier flies larva in contrast with the black soldier flies larvae feeds peanut press pulp not adding dew grass meal.In experimentation, the growth cycle of the black soldier flies larva that the feed having added the shortening black soldier flies larval growth cycle of dew grass meal is fed shortens 2 days compared to control group.
Embodiment 4
Take black soldier flies larvae feeds peanut press pulp 10kg, particle diameter 500 μm of dew grass meal 0.1kg, obtain the feed that can shorten the black soldier flies larval growth cycle after mixing thoroughly, for subsequent use, add water appropriate during each use.After egg hatching 1 day starts to add the forage feed that can shorten the black soldier flies larval growth cycle, reinforced to stopping during prepupa, feeds black soldier flies larva in contrast with the black soldier flies larvae feeds peanut press pulp not adding dew grass meal.In experimentation, the growth cycle of the black soldier flies larva that the feed having added the shortening black soldier flies larval growth cycle of dew grass meal is fed shortens 2.5 days compared to control group.
Embodiment 5
Take black soldier flies larvae feeds peanut press pulp 10kg, particle diameter 500 μm of dew grass meal 1kg, obtain the feed that can shorten the black soldier flies larval growth cycle after mixing thoroughly, for subsequent use, add water appropriate during each use.After egg hatching 1 day starts to add the forage feed that can shorten the black soldier flies larval growth cycle, reinforced to stopping during prepupa, feeds black soldier flies larva in contrast with the black soldier flies larvae feeds peanut press pulp not adding dew grass meal.In experimentation, the growth cycle of the black soldier flies larva that the feed having added the shortening black soldier flies larval growth cycle of dew grass meal is fed shortens 3 days compared to control group.
