Zanthoxylum bungeanum, also known as Sichuan pepper or Chinese prickly ash, is a drought-tolerant, shallow-rooted plant with strong environmental adaptability. In the process of cultivating Zanthoxylum bungeanum, fertilization is crucial. So, what kind of fertilizer is best for Zanthoxylum bungeanum? Let's find out.
What Fertilizer is Best for Zanthoxylum Bungeanum?
1. Nitrogen Fertilizer: Applying nitrogen fertilizer promotes the dense growth of Zanthoxylum bungeanum branches and leaves, enhances nutrient absorption quality, and increases yield.
2. Phosphorus Fertilizer: Applying phosphorus fertilizer improves the root absorption capacity of Zanthoxylum bungeanum trees, strengthens their drought and cold resistance, and enhances fruiting rate and quality.
3. Potassium Fertilizer: Applying potassium fertilizer enhances Zanthoxylum bungeanum's resistance to stress, strengthens the tree, and improves disease resistance.
4. Zinc Fertilizer: Applying zinc fertilizer can prevent symptoms such as small or yellow leaves due to zinc deficiency, enhance leaf photosynthesis, promote obvious fruit swelling, and increase yield.
5. Boron Fertilizer: Applying boron fertilizer can improve the growth and development of Zanthoxylum bungeanum, increase fruit setting rate, stimulate pollen germination, promote pollination, regulate organic acids in Zanthoxylum bungeanum, and promote root growth.
6. Calcium Fertilizer: Applying calcium fertilizer allows calcium ions to regulate the internal environment of Zanthoxylum bungeanum trees, reduce the toxic effects of potassium, sodium, aluminum ions, and ensure the smooth development of the tree.
Fertilization Methods for Different Stages of Zanthoxylum Bungeanum Growth
1. Pre-flowering Fertilization: This fertilization is mainly to supplement the lack of nutrients due to the low amount of autumn base fertilizer and insufficient nutrient storage in the tree, which has a significant effect on increasing the size of fruit clusters, improving the fruit setting rate, and promoting the development of young fruit. Nitrogen fertilizer is the main fertilizer.
2. Young Fruit Stage Fertilization: This fertilization is mainly to meet the needs of fruit growth and development. Nitrogen fertilizer should be applied less, while phosphorus and potassium fertilizer should be applied.
3. Pre-bud Differentiation Fertilization: This fertilization has a significant effect on promoting bud differentiation. Fertilization should be mainly nitrogen and phosphorus fertilizers, supplemented with appropriate potassium fertilizer.
4. Autumn Fertilization: The main purpose of autumn fertilization is to replenish the tree's nutrient deficiency caused by a large number of fruits and solve the contradiction between fruit swelling and bud differentiation for nutrient requirements. The goal is to increase yield, improve quality, promote bud differentiation, and enhance tree nutrient accumulation. From mid to late August to early September, in addition to applying nitrogen fertilizer, potassium fertilizer should be increased.
In conclusion, the above is an introduction to the best fertilization methods for Zanthoxylum bungeanum. Under good management conditions, Zanthoxylum bungeanum trees can be productive in 5 years, and with proper management, their economic lifespan can generally reach 15-20 years, resulting in high yields.
