What fertilizer to use for Chonglou

Paris polyphylla requires a large amount of fertilizer for growth, especially phosphorus and nitrogen fertilizers. However, the use of inorganic fertilizers alone can easily cause soil compaction and root rot. Especially when a large amount of N fertilizer is used, the germination rate and survival rate will be reduced. Inorganic fertilizers can only be used in appropriate amounts in combination with organic fertilizers.

Fertilizer for Paris polyphylla

Using organic fertilizer when planting Paris polyphylla, supplemented with compound fertilizer and various trace element fertilizers can make it grow faster. Organic fertilizers include fully decomposed farmyard manure, livestock manure, oil cake, wood ash, crop straw, etc. Spray foliar fertilizer during the vigorous growth period to promote plant growth. Urea and potassium dihydrogen phosphate can be used for spraying, spray once every half a month, and spray a total of 3 times.

1. Base fertilizer:

The fertilizer for Paris polyphylla is mainly organic fertilizer, supplemented by compound fertilizer and various trace element fertilizers. The organic fertilizer should be composted for more than 3 months before application to ensure full decomposition.

Fertilization method of Paris polyphylla

Paris polyphylla mainly uses organic fertilizer as base fertilizer. After the seeds germinate, if the base fertilizer is sufficient, no topdressing or a small amount of topdressing can be done. Paris polyphylla requires a large amount of fertilizer during the growth period, especially the absorption of nitrogen and phosphorus fertilizers is high. Apply 40g of compound fertilizer or 3kg of farmyard manure per square meter. With the increase of seedling age, the amount and frequency of fertilization should be appropriately increased. During this period, foliar fertilizer can be applied. Foliar fertilizer is generally compound fertilizer. Trace element fertilizer is also needed during this period. Trace element fertilizer is mainly in the form of water irrigation.
