Artificial incubation of silkworm several factors corona

Morningstar silkworm eggs and variety of the herb similar to the results, analysis of variance results also illustrate the different silkworm eggs Morningstar corona placed status of the results are very similar, the hatching rate and death rate of eggs did not reach significant level ( Table 2). Visible, place the state of the silkworm eggs of different corona received stimulation to break the diapause of silkworm eggs is not. As long as the appropriate amount of stimulation Corona, placed the state of silkworm eggs of different corona treatment have access to the high practical hatching rate. But Morningstar's results were significantly lower in all incubation grass, which stimulate the Japanese susceptibility of varieties to the low corona,[link widoczny dla zalogowanych], a larger amount of stimulation required to break diapause in line snapped. 2 Analysis of variance 0Tae2Thea bad book lvsofv stare canthal ① percentage of variance analysis of the data are for!

In a different area of the plate as electrodes, placed on plates of the corona silkworm eggs artificially, which resulted in a large board handling area, Zhejiang Agricultural University, incubation performed significantly worse than the small volume of 24 board processing area. Corona treatment and frozen immediately after corona treatment. Large and small board area of the hatching rate difference of about 5O and 48, respectively, a small board area does not turn green egg ratio is far below the large plate area, death rates of the eggs were not significantly different. Can be seen, the board area is due to most of the low rate of hatching of silkworm eggs is not turning green due to (Figure 2, Figure 3). Meanwhile,[link widoczny dla zalogowanych], the board area by the corona treatment, a halo large plate area under the treatment area was significantly lower than the hatching performance of small plate area processing zones. may be two reasons, one negative rejection of the printed circuit board substrate discharge production. rigid small. a large easily deformed area while mining rejection of welding electrodes made by hand, difficult to discharge needle tip at the same horizontal plane, resulting in uneven discharge. to a Second, the test instrument power corona is too small, so the input power is only 4Ow output power less than 1w. In the same field conditions. Large area multi-plate electrodes, each unit of time the electrodes on the steps of emission electrons to form electron avalanche reached the number of high-energy electron group will lower the total energy carried by electrons decreases. Silkworm eggs suffered high-energy electrons to stimulate the amount is inadequate. So that the lower hatchability of silkworm eggs. Technology in order to artificially produce the corona should be adopted to expand the plate area and the form of scattered eggs corona treatment,[link widoczny dla zalogowanych], thereby increasing the amount of time dealing with the eggs, to improve the efficiency of corona treatment. Scattered eggs placed in an electric field is the state to accept a variety of corona discharge treatment. These results indicate that the silkworm eggs placed in an electric field state of the corona treatment has little effect. San egg layers with different thickness of the corona treatment showed that the thicker layer of loose eggs,[link widoczny dla zalogowanych], silkworm eggs hatching results worse (to be published.) So long as the selection of appropriate thickness scattered eggs, get a better hatching rate is possible and practical. As for the existence of extended incubation plate area the problem of declining performance, according to analysis of the above reasons,[link widoczny dla zalogowanych], you can increase the corona power meter, select the rigid plate made of conductive materials, and change for the peak manual welding electrodes and other means to overcome the dip soldering .
