The second is the mulberry science fertilization method. After the summer cutting and winter cutting, the basic fertilizer was re-used, and the Mushi farmyard fertilizer was 1000 kg + phosphate fertilizer 200 kg + bio-organic compound fertilizer 200 kg or compound fertilizer 100 kg. In mid-February, 40 mu of urea was applied, and after every 2 batches of silkworm reared, 40 mu of urea and 80 kg of compound fertilizer were applied. Mulberry fertilization must be applied to deep ditch in order to increase fertilizer efficiency.
The third is to grasp the key technologies for turning over soil in winter, picking up cores in spring, and protecting insects in summer.
The fourth is to focus on urging, controlling temperature and disinfecting.
