Yet, for a long time, research about " 24h that collects ants dredges hair rate " investigation method rarely has report, counting investigation is checked at the artificial scene of main employing in the industry, open the containers such as the food box of sericulture or culture dish, the 24h that collects ants checking on silkworm artificial feed dredges a hair silkworm number and the silkworm number of always collecting ants, and calculates " 24h that collects ants dredges hair rate ".There are problems in this kind of mode, main manifestations is: when (1) collects ants 24h, and the long 3～4mm of 1 silkworm body in age, silkworm is small, checks that difficulty is large, the operating time is long, accuracy is poor; (2) food pollution that time length and inventory operation itself etc. easily cause sericulture container is checked at scene, affects later stage sericulture work; (3) scene check counting investigation result only have for statistics, not directly perceived, can not check.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple to operate, investigation method that the 24h that collects ants when data acquisition time is short, accuracy good, visual result is easily checked and silkworm artificial feed that can long preservation educates dredges hair rate.
For solving the problems of the technologies described above, the present invention by the following technical solutions: the 24h that collects ants when silkworm artificial feed educates dredges the investigation method of hair rate, comprises the following steps:
<1> takes pictures to the 24h enumeration district of collecting ants with digital camera;
<2> proceeds to computer by the enumeration district picture of digital camera collection and stores;
<3> opens enumeration district picture with drawing software, and statistics is dredged a hair silkworm number and a number of always collecting ants;
<4> calculates with Excel table the 24h that collects ants and dredges hair rate;
<5> is kept at enumeration district picture in computer and rechecks in order to verifying.
Digital camera pixel, more than 8,000,000, adopts microspur, Flash Mode while taking pictures.
Take pictures and must contain all silkworms in enumeration district, and the picture of taking pictures can the clear growing state of seeing silkworm body after drawing software is opened amplification.
Calculate and carry out as follows:
The thin hair of the 24h that a collects ants rate=number/a number * 100% always collects ants to dredge a hair silkworm.
For check at present the problems such as long, difficulty is large, accuracy is poor, easy pollution sericulture container of counting control time due to the artificial scene that silkworm is small, quantity causes the 24h that collects ants to dredge hair rate more, inventor utilizes digital camera to take pictures, picture clear and principle with long preservation period directly perceived still after drawing software amplifies, the 24h that collects ants while educating for silkworm artificial feed dredges the investigation of hair rate.Compare with traditional investigation method, the Test Data Collecting time of the present invention is short, intuitively easily check and can long preservation, can reduce because investigation causes the food pollution of sericulture container, can be widely used in the suitable artificial diet rearing cultivated silkworm breed variety of seed selection, silkworm artificial feed raises and novel silkworm artificial feed's development process in.
