1、 Base fertilizer

When planting seabuckthorn, base fertilizer should be applied first. The purpose of base fertilizer is to continuously provide nutrients. Therefore, organic fertilizer with longer fertilizer effect should be used. The fertilizer should be fully decomposed. If it is fermented in the soil, it will burn the roots of the plant. Generally, the base fertilizer needs to be supplemented every 2-3 years, with 3000-4000 kg per mu

2、 Topdressing

1. Growth period: in the growth period of seabuckthorn, topdressing is needed in time. At this time, fertilization is mainly to promote the growth of plants and the development of branches and leaves, so nitrogen fertilizer is mostly used. Common nitrogen fertilizers include urea and ammonium bicarbonate. Generally, 200-400 grams of urea and 200-300 grams of ammonium bicarbonate are applied per plant

2. Budding period: Seabuckthorn will bloom in summer. If the nutrient is insufficient, the flowering will be delayed or cause flower falling, which will also reduce the fruit setting rate. Therefore, in the budding stage, we should supplement phosphate fertilizer, generally use calcium superphosphate, and apply 200-300g per plant. At the same time, potassium fertilizer should be supplemented, which only needs 100-200 grams per plant

3. Fruit stage: after Seabuckthorn grows fruit, appropriate fertilization is also needed to promote its growth. Fertilization in fruit stage is similar to that in bud stage, which is mainly phosphorus and potassium fertilizer, and more quick acting fertilizer is used. In addition, it can also be sprayed with zhuangguodiling, which can make the fruit expand better

4. After picking: Seabuckthorn needs to consume nutrients for flowering and fruiting. Therefore, appropriate fertilization is required after picking to supplement the nutrients lost before. At this time, the fertilizer is mostly organic fertilizer. Because the climate has turned cold and the plant growth is not fast, the reuse of quick acting fertilizer may cause fertilizer damage, so the application of organic fertilizer is very good
