A Complete Guide to the Latest Fertilization Methods for Nanguo Pear
The Nanguo pear can be said to be the sweetest pear, and many people have probably 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 and directly determines the yield. So today, the editor brings you the fertilization methods for Nanguo pears. Let's take a look!
1. Fertilizer Requirements and Characteristics
The nutritional needs of the Nanguo pear are fairly comprehensive, with the demand for nitrogen fertilizer being the highest, 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 has a demand for trace elements, such as zinc and boron. If trace elements are lacking, it will affect the growth of the Nanguo pear in various ways. For example, a zinc deficiency will affect leaf growth, causing the leaves to become dull and lusterless, thin, small, and weak. The accumulation of photosynthetic substances in the tree body will be insufficient, reducing the fruit-setting rate.
2. Apply Sufficient Base Fertilizer
Base fertilizer is an absolutely indispensable fertilizer when planting Nanguo pears. It is generally applied after the Nanguo pear is harvested, and this period is also the peak growth period for the roots of the Nanguo pear tree. In addition, applying base fertilizer in autumn allows it to be fully utilized in the spring of the following year, with a relatively high conversion rate. 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. It is best to apply base fertilizer together with land preparation, putting the base fertilizer about 45 cm deep into the soil. 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 cultivation of Nanguo pears, topdressing should be done at least three times a year. They are carried out before bud break, during flower bud differentiation, and during the fruit enlargement stage, because the fertilizer demand of the Nanguo pear tree is relatively high during these three periods. During the first topdressing, attention should be paid to controlling the amount of nitrogen fertilizer, with the proportion controlled at about 1/5. It should not be too much, to prevent excessive vegetative growth. Then the second and third topdressings should mainly use potassium fertilizer. This promotes fruit enlargement and improves fruit quality. When topdressing, attention should be paid to controlling the amount of topdressing according to the soil's ability to retain fertilizer and water, to prevent excessive topdressing, which can 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 roots to prevent root burn.
4. Foliar Topdressing
Foliar topdressing is mainly to meet the demand of Nanguo pear growth for trace elements. 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, so as 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 is all for today's introduction.
