Fertilizer selection of African pansy
Because the root system of African pansy is shallow and relatively weak, it is not suitable for applying concentrated fertilizer or organic fertilizer. Adhere to the principle of thin fertilizer and frequent application, a small amount of fertilizer can be applied for many times. Urea, ammonium nitrate and potassium dihydrogen phosphate are suitable for fertilization. They can be used alone or in combination with trace elements. The concentration of spraying on the leaf surface shall not exceed 0.1% and the concentration of irrigation substrate shall not exceed 0.4% p>
Fertilization method of African pansy
The principle of fertilization is to apply fertilizer with high nitrogen content at the seedling stage of African pansy. With its gradual growth, a balanced fertilizer of nitrogen, phosphorus and potassium should be applied. It should be noted that the smaller the seedling, the lighter the fertilizer. Vitamin B solution can be used in the leaf cutting stage of African Viola, which can promote plant rooting and germination. Remember not to apply fertilizer within one month after transplanting seedlings, otherwise it is easy to cause rotten seedlings. Then use fertilizer with high nitrogen content to promote leaf growth and luster. The fertilizer applied after the seedlings grow up should pay attention to the balanced proportion of nitrogen, phosphorus and potassium to promote plant growth. When the African pansy plant matures and enters the flowering stage, the fertilizer with high phosphorus content should be used to promote the differentiation of flower buds and blossom early. Generally, liquid fertilizer should be applied every 10-20 days, and the fertilizer with high phosphorus content should be applied before flowering. When phosphorus and potassium fertilizer is needed after flowering, do not apply too much nitrogen fertilizer, otherwise it will cause lush leaves but no flowering. Spray can be used for spraying or watering the pot. span>
