Spring fertilizer is also called bud-promoting fertilizer, generally applied before the mulberry tree develops, mainly quick-acting chemical fertilizers. The application rate of spring fertilizer accounts for about 25%-30% of the annual fertilization amount. It is generally applied in two rounds: once in late March, applying 1000-1500 kg of manure and urine fertilizer per mu, and about 2 kg of urea; the first application amount is about 70% of the total spring fertilizer. The second fertilization is in late April, applying about 10 kg of urea per mu is enough, to promote the growth of young buds.

2. Summer fertilizer for mulberry

The application time of summer fertilizer is generally from summer pruning of the mulberry tree to before rearing the early autumn silkworms, and it is likewise applied in two rounds. The first fertilization is carried out immediately after summer pruning; the fertilizer should be organic fertilizers such as barnyard manure and compost applied together with chemical fertilizers, generally applying about 1000 kg of manure per mu, 30 kg of urea, and about 15 grams of phosphate fertilizer. The second fertilization is carried out after bud thinning, when the fertilizer should mainly be quick-acting chemical fertilizers, applying 15 kg of urea per mu. The summer fertilizer application rate is generally 40%-50% of the annual fertilization amount.

3. Autumn fertilizer

The application time of autumn fertilizer is generally after the autumn mulberry leaves are harvested. Autumn fertilizer should not be applied late, and at the latest must not exceed August; otherwise, the delayed growth of branches and tips makes them highly susceptible to frost damage. Autumn fertilizer should mainly be quick-acting fertilizer. Under normal circumstances, applying about 15 kg of urea per mu is suitable, and the application rate of autumn fertilizer generally accounts for about 10%-20% of the annual fertilization amount.

4. Winter fertilizer

Winter fertilizer is applied before the soil freezes in winter. The winter fertilizer application rate generally accounts for about 20% of the annual fertilization amount.
