The latest Nanguo pear fertilization method
Nanguo pear can be said to be the sweetest pear, presumably many people have not eaten it. Because Nanguo pear is a unique pear variety in northeast China, but with the development of the Internet, Nanguo pear is now available all over the country. Therefore, the planting area is getting larger and larger, when planting Nanguo pear, fertilization is very important, which directly determines the yield. So the editor brought the fertilization method of Nanguo pear today, let's have a look!
1. Characteristics of fertilizer requirement
The nutritional requirements of Nanguo pear are relatively comprehensive, in which the demand for nitrogen fertilizer is increased, followed by phosphorus and potassium fertilizer. Adequate fertilizer can provide Nanguo pear with nutrients for its growth. And Nanguo pear in the growth, there is also a demand for trace elements, such as zinc, boron and so on. If there is a lack of trace elements, it will affect the growth of Nanguo pear in all aspects. For example, zinc deficiency will affect the growth of leaves, resulting in dull, thin and weak leaves. The accumulation of photosynthetic matter in the tree is insufficient, which reduces the flower and fruit rate.
2. Apply sufficient base fertilizer
Base fertilizer is an absolutely indispensable fertilizer when planting Nanguo pear. It is generally applied after Nanguo pear harvest, which is also the peak period of root growth of Nanguo pear tree. And the application of base fertilizer in autumn can be fully utilized in the spring of the second year, and the conversion rate is higher. Base fertilizer is generally based on farm manure, combined with an appropriate amount of phosphate fertilizer. If the tree is older, then nitrogen fertilizer can be increased appropriately to promote the restoration of tree potential after harvest. Base fertilizer is best combined with soil preparation, the base fertilizer will be deep into the soil about 45 cm. Ditch application, hole application and ring application are the main methods to ensure the nutrition needed for the growth of Nanguo pear.
3. topdressing at the right time
During the planting period of Nanguo pear, topdressing at least three times a year. It was carried out before sprouting, flower bud differentiation and expansion period, because the fertilizer demand of Nanguo pear tree was relatively large in these three periods. When topdressing for the first time, we should pay attention to control the amount of nitrogen fertilizer, the proportion should be controlled at about 1 to 5, not too much, to prevent prosperous growth. Then potash fertilizer was the main topdressing for the second and third times. Promote fruit expansion and improve fruit quality. When topdressing, we should pay attention to control the amount of topdressing according to the ability of soil to preserve fertilizer and water, so as to prevent excessive topdressing, lead to fertilizer damage and increase planting cost. Topdressing should be determined according to the size of the crown, mainly in ditches, and keep a certain distance from the roots to prevent root burning.
4. Extra-root topdressing
The main purpose of extra-root topdressing is to meet the demand of trace elements for the growth of Nanguo pear. Generally, foliar fertilizer is mainly sprayed, and nitrogen fertilizer is mainly used when foliar fertilizer is sprayed in autumn to improve the growth ability of leaves and promote leaf photosynthesis. Then properly spraying phosphorus and potassium fertilizer can improve the cold resistance and disease resistance of Nanguo pear tree and enhance the yield of Nanguo pear tree. However, 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 a brief introduction to the fertilization method of Nanguo pear. The growth of Nanguo pear has a great demand for nutrition, so we must do a good job in fertilization. That's all for today's introduction. This article is for reference only. I hope it can help you all.
