Improve the hatching rate of day three of the original species Incubation measures

Do not get E, after the slow development of the species (such as Ming Hu A, Yellow A, B, etc.) should be held by the 5th day afternoon. See point 2.3, see 2.3.1 and development time line, see the arrival time is the key time of incubation, hatching rate is taken to improve the day the key to the final remedy. Three of the original species see some time we usually lies in: the original of the original parent species, the original of the original species of Japanese for the first 9 days 2 to 6, in line for the first 9 days 0 to 4, the original species of Japanese for the first 9 days 0 ~ 4, in line for the first 8 days 9 days 22:00 to 2:00. However, large differences between species,[link widoczny dla zalogowanych], the low rate of day turning green varieties should see the point in question to reach the attention regulation. 2.3.2 timely development of line is a group of silkworm rearing, even if the same batch, the same species, the same source of eggs, development of the individual to ask or have some differences, which developed the original line up are three types of points will see to do a job, see point queue timely, timely protection also contributed to the dark incubation of homogeneity, an important measure to improve the hatching rate of day. The decision is based on queue time see time, usually in the first 9 days and 10 pm for morning, queuing general three types (early, middle and late, for a large number), select the same time the eggs will be dead in incubation occurred more eggs, the moths circle very uneven, to be removed, the original species of the original mother wrapped in tissue paper, and to be fixed; original seed, the original species in the same class, in accordance with the time scale in each district be moth hatched circle number,[link widoczny dla zalogowanych], and even fixed in a blank piece of paper is also wrapped with tissue paper,[link widoczny dla zalogowanych], put in moth inside the box or the leads (lead sheet box put the original species), in time into the dark room, into the dark room at the same time, we must ask according to species speed of development of compartment to be protected to ensure that the incubation homogeneity. 3, the late well protected area 3.1 Incubation of the original species of silkworm silkworm field of transport The transport of incubation of the original species of silkworm area by involving a wide range and the large number of transport trips and more, and different way, with hair types climate variability Shiyou straight seasons (spring, close to the beginning of summer, seasonal change; autumn temperature difference between day and night, dry climate..) Incubation of the original species to be safe destinations, without affecting the hatching day. 3.1.1 arrange trips in the first before the original species should the audience see the point of the original point of the original silkworm seed time, location, line line up, talk to the capacity of the vehicle, according to ranking. 3.1.2 make preparations prior to transport 1, 2007 Jiang die of hunger before the first protected in the dark place of lead sheet boxes of silkworm eggs posted good label. Incubation in the front room again with a cotton intercropping wrap, and fasten the cotton intercropping out the same label, the last written list of the vehicles cross the guard, staff. 3.1.3 determine the degree of development of transport and the moment when the Cotyledons Cotyledons turning green on the outside is very sensitive to temperature changes, transport Cotyledons very important to determine the degree of development, through test and production practice, that turn green for more than 90% most good. Transport time depends on the degree of development of meteorological and Cotyledons depending on the degree of development in the Cotyledons standards, the usual transit time in the spring of 0.5 to 2 hours, hatched the same day in the morning around 5:00; 2 to 5 hours of the closing ants, every other day beginning at noon 12:0 o; over 5 hours of the morning the next day in the hatched 8 ~ 9: O0 start. If the fall in the hatched climate stability on transportation, in case the temperature is too high too low transit time in 1 to 2 hours in the day of operation hatched, otherwise shipped next day. 3.1.4 The environment inside the vehicle interior temperature and humidity directly affect the hatching rate of silkworm eggs, transport should be a good vehicle to keep the temperature, humidity and light (silkworm eggs should be kept absolutely dark), in particular, make sure to wet work well. 3.2 is a good complement incubation of silkworm eggs by incubation fill transport the protection of arrival, the work done is good or bad day would be directly affected by hatching. Original seed base in general we are doing better,[link widoczny dla zalogowanych], and the original silkworm area is slightly hearing. We are based on the actual situation of the original silkworm area, when the Cotyledons in the incubation room was old and some reminders, a total of education into the room, resident technical expertise required sericulturist publicity make Incubation of the importance of temperature and humidity to the situation supervision and inspection to ensure the temperature and humidity maintained at: 25.5 ~ C hatched the next day or so of wet and dry difference is 1.5 ~ C, hatched difference between wet and dry day is 27 �� lower than 1.5 ~ C. While strengthening ventilation to keep silkworm absolute darkness, to achieve a homogeneous hatch hatched. Incubation 3.3 Incubation of the original species in the case of cold weather anomalies, such as the case of strong cold or late frost in spring, large areas of frozen mulberry buds; autumn typhoon, leaves are broken hatched,[link widoczny dla zalogowanych], not hatched in the schedule When used in the production of cold incubation of silkworm eggs to adjust. See generally use the switch to green seedlings ant eggs refrigerated, Time in the production of not more than 3 days, if over 3 days, then asked to turn in the same varieties of cold storage method in advance, so that storage time is relatively short. Be sure to go through in the middle of cold temperatures, to prevent access to undesirable gases, maintain absolute darkness, and strictly enforce the shift change and labeling system to prevent confusion.
