How to Fertilize Nanguo Pear? Detailed Explanation of Scientific Fertilization Methods
The Nanguo pear can be said to be the sweetest of pears, and surely many people have never tasted one. This is because the Nanguo pear is a pear variety unique to Northeast China, but with the development of the internet, Nanguo pears are now available all over the country. As a result, the planting area is also growing larger and larger. When growing Nanguo pears, fertilization work is very important, as it directly determines the yield. So today, the editor brings you the fertilization methods for Nanguo pears. Let's take a look together!
1. Nutrient Requirements
The nutritional needs of the Nanguo pear are relatively comprehensive, with the demand for nitrogen fertilizer being the greatest, followed by phosphorus and potassium fertilizers. Sufficient fertilizer can provide the nutrients needed for the growth of the Nanguo pear. Moreover, during its growth, the Nanguo pear also requires trace elements, such as zinc and boron. If trace elements are lacking, it will affect the growth of the Nanguo pear in various aspects. For example, a zinc deficiency will affect leaf growth, causing the leaves to be dull and lusterless, thin and weak. Insufficient accumulation of photosynthetic substances in the tree body reduces the rate of flowering and fruiting.
2. Applying Sufficient Base Fertilizer
Base fertilizer is an absolutely indispensable fertilizer when growing Nanguo pears. It is generally applied after the Nanguo pears are harvested, and this period is also the peak growth period for the roots of the Nanguo pear tree. Moreover, applying base fertilizer in autumn allows it to be fully utilized in the spring of the following year, with a relatively high conversion rate. The base fertilizer is generally mainly farmyard manure, combined with an appropriate amount of phosphate fertilizer. If the tree is older, then nitrogen fertilizer can be appropriately increased to promote the recovery of tree vigor after harvest. The base fertilizer is best applied together with land preparation, applying the base fertilizer deep into the soil at about 45 cm. Trench application, hole application and ring application are the main methods, ensuring that the nutrients needed for the growth of the Nanguo pear are satisfied.
3. Timely Topdressing
During the growing period of Nanguo pears, topdressing should be done at least three times a year. These are carried out before germination, during flower bud differentiation and during the expansion period, because the fertilizer demand of the Nanguo pear tree is relatively large during these three periods. At the first topdressing, attention should be paid to controlling the amount of nitrogen fertilizer, with the proportion controlled at about 1/5, not too much, to prevent excessive vegetative growth. Then the second and third topdressings are mainly potassium fertilizer, to promote fruit expansion and improve fruit quality. When topdressing, attention should be paid to controlling the amount according to the soil's ability to retain fertilizer and water, to prevent excessive topdressing, which would cause fertilizer damage and increase planting costs. When topdressing, it should be determined according to the size of the tree canopy, mainly by trench application, keeping a certain distance from the tree roots to prevent root burn.
4. Foliar Topdressing
Foliar topdressing is mainly to meet the demand of the Nanguo pear for trace elements during growth. It is generally mainly done by spraying foliar fertilizer. When spraying foliar fertilizer in autumn, nitrogen fertilizer is mainly used to improve the growth capacity of the leaves and promote photosynthesis in the leaves. Then appropriately spraying phosphorus and potassium fertilizers can improve the cold resistance and disease resistance of the Nanguo pear tree and enhance its yield. However, when spraying foliar fertilizer, we should mainly carry out targeted spraying, paying attention to supplementing the trace elements that the Nanguo pear lacks accordingly, to improve the yield and quality of the Nanguo pear.
The above is a brief introduction to the fertilization methods for Nanguo pears. The growth of Nanguo pears has a relatively large demand for nutrients, so everyone must do a good job in fertilization! That's all for today's introduction.
