How to fertilize lettuce in autumn and winter? Please give guidance on planting lettuce in autumn and winter. You can refer to the following methods for fertilization. 1. Principles of fertilization for lettuce in autumn and winter: (1) increase organic fertilizer, control nitrogen fertilizer, increase phosphorus and potassium fertilizer; (2) fertilizer distribution is mainly based on base and topdressing; fertilizer topdressing is mainly nitrogen fertilizer and rational application of potassium fertilizer; (3) serious acidified vegetable garden, acid soil conditioners such as lime should be applied appropriately; 4.

(3) the yield level is 25003500kg / mu: nitrogen fertilizer (N) 1416kg / mu, phosphate fertilizer (P2O5) 5kg / mu, potash fertilizer (K2O) 6kg / mu. (4) the yield level is 15002500kg / mu: nitrogen fertilizer (N) 1214kg / mu, phosphate fertilizer (P2O5) 4kg / mu, potassium fertilizer (K2O) 5kg / mu.
