Methods of applying basal fertilizer to kiwifruit in autumn of different ages.
With the continuous development of the kiwifruit industry, fertilization technology has also become the focus of attention of fruit farmers. Among them, autumn fertilization plays a vital role in the growth and yield of kiwifruit. However, there are also some differences in the fertilization of kiwifruit in autumn for different tree ages. This article will introduce in detail how to apply basal fertilizer to kiwifruit of different ages in autumn.
1. Young trees.
For young kiwifruit trees, autumn fertilization should be aimed at promoting plant growth, expanding the canopy, and improving disease resistance. Specifically, it can be at a distance of 1 from the trunkDig a ring ditch about 30 cm deep at a position of about 5 meters, then apply an appropriate amount of organic fertilizer and compound fertilizer, and finally cover the soil and water. At this time, it is necessary to pay attention to controlling the amount of fertilizer to avoid problems such as root burning caused by excessive fertilization.
2. Mature trees.
For mature kiwifruit trees, autumn fertilization should be aimed at increasing yield, improving quality, and promoting flower bud differentiation. Specifically, a circular trench about 40 cm deep can be dug at a distance of about 2 meters from the trunk, and then an appropriate amount of organic fertilizer, compound fertilizer and trace element fertilizer can be applied, and finally the soil can be covered and watered. At this time, it is necessary to pay attention to controlling the amount of fertilizer to avoid problems such as root burning caused by excessive fertilization.
3. Flourishing trees.
For kiwifruit trees in full bloom, autumn fertilization should be aimed at maintaining tree strength, prolonging lifespan, and improving disease resistance. Specifically, it can be at a distance of 2 from the trunkDig a circular ditch about 50 cm deep at a position of about 5 meters, then apply an appropriate amount of organic fertilizer, compound fertilizer and biological fertilizer, and finally cover the soil and water. At this time, it is necessary to pay attention to controlling the amount of fertilizer to avoid problems such as root burning caused by excessive fertilization.
In conclusion, there are certain differences in the fertilization of kiwifruit in autumn among different tree ages. Growers need to choose and adjust their fertilization according to the actual conditions of their orchards to ensure that the growth and yield of kiwifruit are optimal. At the same time, it is also necessary to pay attention to the safety of fertilization to avoid personal injury or property damage due to improper operation.
