The advantages of using this method:
1, to avoid the rice, wheat and other straw pollution caused by pesticides to bring traces of pesticide poisoning so that does not produce tussah.
2, reduce the number of times, improve the rate of upload.
3, improve the quality of oysters, increase the amount of wire.
4, neat white and tidy, uniform thickness and layer, the solution to improve the rate.
5, convenient picking, less chemical. Its use method:
First, put on the cluster method: 1 method is more commonly used, the two borders of the two clusters in the same direction to pull together, with a 1.3 meters long bamboo attached to the long border of the two clusters, with The lead wire is fastened, generally a silkworm species needs 150 square clusters, ie 75 pairs of double clusters. The clusters should be set up before the tufts. The tufts can be arranged in one house or two depending on the number of sericulture and housing conditions. However, it is better to use no more than three tiers. The bottom tiers are not less than 40 centimeters from the ground. The floor under the shelf is covered with straw or plastic cloth, and the double cluster pieces will be discharged on the ground and evenly spread on mature silkworms. After 5-10 minutes, the mature silkworms will be set and gently picked up in order. Shelved on the previously erected shelves, when hanging, the two tufts should be 10-15 cm apart, but not too close, otherwise the larvae will accumulate in the middle of the tufts. Hanging cluster order from one end to the other end, hanging up and down two layers at the same time, starting the upper cluster and the lower cluster are basically close, but must be vertical to avoid contamination of the lower layer when the upper layer of mature silkworm urine excrement. When the majority of mature silkworms enter the hole after the camp, they must catch the mountain silkworm in time.
Second, the silkworm automatically cluster method.
The automatic clustering method of the silkworm is also called the natural cluster method. This method is based on the silkworm rearing. The method is simple, labor-saving and labor-saving. The number of clusters that can be needed is the same as above. When the larvae are cooked, about 5% of them are bred with ecdysone. After the silkworm mulberry leaves are basically eaten, they are hung on a double cluster. The two-leaf spacing is 10-13 cm, allowing the mature silkworm to climb on its own. Do it. This method can save the effort of catching mature silkworms, and clearing the field is also more convenient. However, when laying silkworms, the width should be slightly less than the length of the double clusters. If the mulberry silkworm culture should be changed to the leaf one day before the appearance, the shelf should be raised after the oyster shell is formed to facilitate ventilation.
Third, strengthen cluster management after clustering.
1, clear the field. Clearing the field is to take out the clusters on the outside of the cluster hole and find out the position of the larvae. Clearing up the market must be timely, clearing out the silkworms too early, wasting labor and clumps, too late will affect production. When most of the larvae have entered the estuary, it will be timely for the larvae to catch the larvae. In general, the silkworms are 24 hours after they are clustered.
2, timely recovery of scattered silkworm and picking and landing silkworm. Mature silkworms like to crawl. They must climb individual silkworms and a few landing silkworms hanging on clusters to pick up another tuft to avoid loss.
3, the light should be uniform. Mature silkworms are protected from light and prevent polarized light or direct light from the clusters. The light should be even and dull.
4, strengthen ventilation and humidity. Due to the large number of cooked silkworms clustered into the holes in the unit space, the amount of urine and feces excreted by the larvae also increases, causing the humidity in the cluster to increase. Therefore, focus on the ventilation and dehumidification of the windows in the first three days after the tufting to keep the clusters clean and dry.
5, temperature. After clustering, the standard temperature of the cluster chamber should be controlled at 24°C (75.0?). If it is lower than 22°C (72°C) or less, it is necessary to use micro-fires to warm up in order to influence the entrance speed and entrance rate.
6, timely pick. The appropriate time for picking the pods depends on the degree of pupa. Generally, the silkworm pupa body is yellowish-brown for a suitable period, and it has a great influence on the quality of the quail.
