Fertilization method of Nanguo Pear

Nanguo pear, a specialty of Liaoning, is a kind of fruit variety which needs unique iron-rich soil to grow. It has the reputation of "king of pears". So, what is the fertilization method for Nanguo pear? Let's get to know it together.

1. Characteristics of fertilizer requirement

The nutritional demand of Nanguo pear is relatively comprehensive, in which the demand for nitrogen fertilizer is relatively large, followed by phosphorus and potassium fertilizer, sufficient fertilizer can provide nutrition for Nanguo pear growth, and when Nanguo pear is growing, there is also a demand for trace elements, such as zinc, boron, etc., if there is a lack of trace elements, it will affect the growth of Nanguo pear in various aspects, such as zinc deficiency. It will affect the growth of leaves, lead to dull leaves, thin and weak, insufficient accumulation of photosynthetic matter in trees, and reduce the rate of flowers and fruits.

2. Apply sufficient base fertilizer

Base fertilizer is an absolutely indispensable fertilizer when planting Nanguo pear, which is usually applied after Nanguo pear harvest, this period is also the peak of root growth of Nanguo pear tree, and the autumn application of base fertilizer can be fully utilized in the spring of the following year, and its conversion rate is higher. The base fertilizer is generally mainly farm manure, combined with an appropriate amount of phosphate fertilizer, if the tree age is older, it can appropriately increase nitrogen fertilizer and promote the restoration of tree potential after harvest. The base fertilizer is best combined with soil preparation, the base fertilizer is about 45 cm deep in the soil, mainly ditch application, hole application and ring application, to ensure to meet the nutrients needed for the growth of Nanguo pear.

3. topdressing at the right time

During the planting period of Nanguo pear, topdressing is carried out at least three times a year, respectively before budding, flower bud differentiation and expansion, because the fertilizer demand of Nanguo pear trees in these three periods is relatively large, so we should pay attention to control the amount of nitrogen fertilizer in the first topdressing, the proportion should be controlled at about 1x5, not too much, to prevent growth, the second and third topdressing is mainly potash fertilizer, the purpose is to promote fruit expansion and improve fruit quality. In topdressing, attention should be paid to controlling the amount of topdressing according to the ability of soil to preserve fertilizer and water, so as to prevent excessive topdressing, resulting in fertilizer damage and increasing planting cost. topdressing should be based on the size of the crown, mainly in furrow application, and keep a certain distance from the roots to prevent root burning.

4. Extra-root topdressing

Extra-root topdressing is mainly to meet the needs of trace elements for the growth of Nanguo pear, generally spraying foliar fertilizer, and nitrogen fertilizer when foliar fertilizer is sprayed in autumn to improve leaf growth ability and promote leaf photosynthesis. Then proper spraying of phosphorus and potassium fertilizer can improve the cold resistance and disease resistance of Nanguo pear tree and enhance the yield of Nanguo pear tree. When we spray foliar fertilizer, we should mainly carry out targeted spraying, pay attention to supplement the lack of trace elements in Nanguo pear, and improve the yield and quality of Nanguo pear.

The above is the fertilization method of Nanguo pear, master the fertilization method in order to produce high-quality and high-yield Nanguo pear, we must learn!
