1，积极做好补充培育和共培养工作。在播种前1天，将蚕室加热至24摄氏度。将蚕种植在房间后，补充它们。首先在蚕茧中涂抹 - 张抗干纸，然后涂白纸，将蚕蛋涂在白纸上，每只蚕卵产蛋面积30厘米及以上; 35厘米，鸡蛋盖 - 压下鸡蛋网，然后覆盖蚕茧。蚕室保持黑暗，温度为24摄氏度。干湿之间的差异是1摄氏度和2摄氏度。保护期为2天，蚂蚁在蚂蚁前的温度升至25.5摄氏度。同时，合格的农民应积极组织小蚕共同培育，全面实施黑火升温，消除明火升温，保证室温下家蚕的安全和人蚕的安全。

桑叶应该适合老年人。今年桑树萌芽后，但后期气温上升较快，桑叶迅速生长。这可能导致桑叶的成熟度不足。因此，最好选择合适的老年时期的桑叶质量。对于尚未施用于春季施肥的桑园，应及时补充春季施肥，以提高亩产质量。

3.完全消毒。近年来，家蚕病的主要原因是蚕农的防病意识差，修复和防光，在养蚕，养蚕，养蚕前没有彻底消毒。特别是今年，由于早期的低温，春蚕的整体饲养较晚，大蚕的后期有可能出现高温。因此，大多数家蚕农民应提高防治意识，对蚕的生产实施全面彻底的消毒和防病措施。在整个过程中，将加强消毒和疾病预防工作，最大限度地减少家蚕病害。

4.做好推广批次，消除疾病和弱蚕的工作。当70％至80％的蚕正在睡觉时，网被添加到果岭中，并且将网添加到果岭的时间在睡眠后不超过10小时。绿头是分批饲养的，这样他们就可以安然入睡，坚决消灭病弱的蚕。

5, the large silkworms are kept ventilated. In the silkworm rearing, it is accustomed to raising small silkworms to raise light silkworms, especially in the late stage of large silkworms.

In the middle of the management, the temperature is between 23 degrees Celsius and 25 degrees Celsius, the humidity is 65% to 75%, and the airflow is 0.5 to 1 meter per second. When the silkworms are positioned in the camp, most of them have formed a thin skin, when the mountain is 2, Open the doors and windows to ventilate and ventilate, pick up the mountain silkworms, strengthen the ventilation, reach the camping process fast, the silkworms have less silk, improve the quality of the enamel, and do the timely picking, to eliminate the sale of the hairy scorpions, in the mining When picking up and selling the upper and lower jaws separately, do not artificially destroy the quality of silkworm cocoons to increase the economic benefits of spring silkworm production.
