Fertilization method of silkworm

1. Types

The choice of fertilizer needs to be determined according to different growth stages. Spring is the vigorous growth stage, when the growth will be relatively vigorous. At this time, nitrogen fertilizer can be selected as the main type, and phosphorus and potassium fertilizers as auxiliary fertilizers. In the later growth process, try to use phosphorus fertilizer as the main fertilizer, which can promote the growth of its leaves and rhizomes. This is the most suitable type of fertilizer.

2. Time

Fertilizer can be applied after the temperature stabilizes in spring. For the Yangtze River Basin, the time to apply fertilizer is around April. This will have a more significant effect and can produce good results. Autumn is also a growing period, and fertilizers can be applied to supplement growth. During the dormant period in summer and winter, no fertilizer is needed, otherwise it will cause root burn.

3. Frequency

It does not require much fertilizer. If the loam is fertile, it does not need too much fertilizer. Just apply a small amount of thin fertilizer. It is enough to provide nutrients about 1-2 times a month, the frequency does not need to be too high.

IV. Methods

Apply fertilizer to the soil to make it fertile and nutritious, so that the silk can absorb nutrients. Be careful not to apply it on the leaves, otherwise it will burn the leaves and affect the appearance. It should also be combined with watering, and water should be applied to dilute the fertilizer after fertilization.
