Background technology
Plant Sang Yangcan and originate from China, so far the history of existing more than 5000 year.Silkworm has another name called silkworm, is oligophagy insect, mainly takes food mulberry leaf, produces still main mulberry leaf so far and raises silkworm.For realizing Labor-saving, scale is bred silkworms, and Japan is in nineteen thirty first logist's artificial diet of silkworm, and 1977 start to promote rearing young silkworm with artificial diet.20 century 70s, China also begins one's study silkworm artificial feed, and current artificial feed are bred silkworms and are still in laboratory and rural area pilot phase.The ration size of silkworm to artificial feed evaluates one of silkworm artificial feed, cultivated silkworm breed variety and the key index promoting artificial feed sericulture technology.Zhang Shengxiang System Approach 24h dredges a mao rate, 96h2 to play silkworm rate age, 168h survival rate, 3 age the selective goal such as hibernating worm body weight effect; Li Weiguo etc. study discovery, when the higher appropriate to the occasion employing of artificial feed bean powder content " 24h that collects ants dredges hair rate " is selective goal.Long 2 ~ the 3mm of newly-hatched silkworm body and the whole body is covered with bristle, body colour be brown or black, and take food rear health and become large, body colour shoals, and this process is called " thin hair "." 24h that collects ants dredges hair rate " namely collect ants 24h time, 1 age silkworm dredge the percentage that burr number accounts for a number of always collecting ants." 24h that collects ants dredges hair rate " reflects that silkworm is to the investigation index of artificial feed ration size, and domestic and international silkworm industry educates the field extensive uses such as cultivated silkworm breed variety seed selection silkworm artificial feed's development, suitable silkworm artificial feed.
But, for a long time, research about " 24h that collects ants dredges hair rate " investigation method rarely has report, manual site is mainly adopted in the industry to check counting investigation, namely the container such as food box or culture dish of sericulture is opened, the 24h that collects ants checked on silkworm artificial feed dredges hair silkworm head number and silkworm head 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: (1) collect ants 24h time, the long 3 ~ 4mm of 1 silkworm body in age, silkworm is small, checks that difficulty is large, the operating time long, poor accuracy; (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 intuitively, can not check.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of simple to operate, data acquisition time is short, accuracy good, visual result is easily checked and the silkworm artificial feed that can preserve for a long time educates time the 24h that collects ants dredge the investigation method of mao 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 mao rate, comprises the following steps:
<1> digital camera is taken pictures to 24h enumeration district of collecting ants;
The enumeration district picture of digital camera collection is proceeded to computer and stores by <2>;
Enumeration district picture is opened by <3> drawing software, and statistics dredges hair silkworm head number and a number of always collecting ants;
<4> Excel shows the calculating 24h that collects ants and dredges hair rate;
Enumeration district picture is kept in computer and rechecks in order to verifying by <5>.
Digital camera pixel, more than 8,000,000, adopts microspur, Flash Mode when taking pictures.
To take pictures all silkworms must contained in enumeration district, and picture of taking pictures open through drawing software can the clear growing state seeing silkworm body after amplification.
Calculate and carry out as follows:
The 24h that collects ants dredge hair rate=dredge hair silkworm head number/always collect ants a number * 100%.
The problems such as counting control time is long, difficulty is large, poor accuracy, easily pollution sericulture container are checked due to the manual site that silkworm is small, quantity causes the 24h that collects ants to dredge mao rate more for current, inventor utilizes digital camera to take pictures, picture is still clear and principle with long preservation period directly perceived after drawing software amplifies, and the 24h that collects ants when educating for silkworm artificial feed dredges the investigation of mao rate.Compared with traditional investigation method, the Test Data Collecting time of the present invention is short, intuitively easily check and can preserve for a long time, can reduce because investigation causes the food pollution of sericulture container, can be widely used in that seed selection is suitable for artificial diet rearing cultivated silkworm breed variety, silkworm artificial feed raises and in novel silkworm artificial feed's development process.
Accompanying drawing explanation
Fig. 1 is that the silkworm artificial feed of the present invention 24h that collects ants when educating dredges the flow chart of the investigation method of mao rate.
