Mulberry mulching is generally conducted in early June or mid-October. At this time, straw resources are abundant, and some mulberry branches and leaves are harvested and the operation is more convenient. The mulberry field that needs to be turned over in winter advocates covering the grass in summer so that the intervals are long and the straw is perishable. In general, 800-1000 kilograms of grass cover per mu of mulberry field, colder areas in winter, the amount of grass in autumn can be increased to 2000-3000 kilograms per acre. The grass-covered mulberry garden ditch should be unobstructed to prevent the accumulation of stagnant water in the rainy season. The straw floats and blocks the drainage ditch. After the summer mulberry field is covered with grass, the soil is moist and the temperature is appropriate, which is conducive to snail breeding. Prevention and control should be strengthened.
