1. Make earthworms. The mud was ploughed and broken up and then sprinkled with water to moisten it. Then the mud was used to make a round soil mortar with a height of 10 cm, a diameter of 7 cm, and a diameter of 3 cm (a hole to prevent water accumulation).
2. Select the seedbed. Cuttage seedlings should be selected for high dryness, flatness, sufficient sunlight, near water sources, and easy management. Seedbed ditching around. Before the cuttings, the earthworms were plum-shaped and placed in the bed, with about 220 rows per square meter.
3. Timely cutting. Mid-Autumn Silkworm or Late Autumn Silkworm is suitable for the cutting period (ie, early October). Half a month after cutting can take root.
4. Select shear cuttings. Choose a robust, upright, semi-lignified, mulberry, cut the upper 15-18 cm for cuttings, generally 3 pitches is appropriate, that is, "3 4 buds." Cut most of the leaves on the top of the cuttings, leaving the size of the duck eggs and cutting them into an arc. The rest of the leaves are cut off with scissors at the base of the petiole. The upper cutting edge of the cuttings was 0.4 cm away from the bud, and the lower end of the cutting was close to the leaf marks. The root buds near the end buds and the lower leaves could not be cut. The cuttings should be cut in the morning or evening. It is best to insert them with the scissors; or stand upright in the clean water basin to prevent the cuttings from losing water and affect the survival rate.
5. Insert the cassette. It is advisable to insert half of the cuttings into the borehole. Two buds should be inserted into the yellow sand. And spray water at any time (in order to spray the yellow sand in the boring hole and surface, but does not cause the bed area of ​​water is appropriate). Finally, cover the film and cover the grass in the morning.
6. Plug in management. 1 timely spray. After spraying, water was sprayed every 23 days for 15 days. After that, the soil and yellow sand were moistened in a timely manner. Within 20 days after insertion, if the sunlight is strong before and after noon, cover the straw on the film (do not cover in winter). 3 pay attention to insulation. The film should be sealed and no cold air can enter the bed. After the seedlings have fallen off, the film is lifted and the screened fine soil (about 1 cm above the surface) is covered in the gap between the surface and the gills, and the film is then covered. To prevent the wind from blowing the film and the water on the bed. 4 pay attention to refining seedlings. Before transplanting, part of the membrane was ventilated during the day and the film was kept warm at night. After 2 to 3 days, the film was removed. Pay attention to water spray during the hardening period to keep the soil moist.
7. Timely transplanting. By March, more than 10 roots per root can be found, with a root length of about 15 cm. Transplant from late March to April 10th. Transplanting seedlings and land should be selected land fertile, irrigation and irrigation conditions better land. Every 667 square meters before planting manure fertilizer 1500 to 2000 kg, transplanting after the ditching. Transplanting plant spacing is 2616 cm, 1.2 to 15,000 plants per 667 square meters. When planting seedlings from the seedbed in turn.
8. Mulberry management. In mid and late May, when the seedling height is 25 to 30 centimeters, 750 to 1,000 kilograms of thin manure per 667 square meters, 10 to 15 kilograms of standardized fertilizer, and about 2,000 kilograms of manure per 667 square meters during July to August Fertilizer 20-25 kg. At the same time, we must promptly do a good job of irrigation, weeding, loose soil, pest management and other work. According to the survey, the average plant height was about 1.7 meters in the current year. Each 667 square meters of cutting seedlings can support about 3 species of summer and autumn silkworms.
