What are the precautions for fertilizing pear trees in autumn?
After the pear harvest is complete, applying sufficient basal fertilizer in time is beneficial for producing high-quality pears the following year. Applying basal fertilizer to pear trees in autumn plays a major role in their growth and development: from September to November, the root system enters its second peak growth period, and fertilizing at this time not only facilitates the rapid decomposition of fertilizer but also helps new roots absorb and store nutrients.
Choose high-quality organic fertilizer
Basal fertilizer should mainly consist of organic fertilizer. Generally, apply about 50 kg of decomposed farmyard manure or barnyard manure per pear tree, combined with 1 kg of superphosphate and 0.2-0.5 kg of urea, or 0.5-2 kg of refined organic compound fertilizer such as Huimanfeng or Diletan. The basal fertilizer application amount should account for 60%-70% of the annual fertilizer use.
Use flexible application methods
The application method of basal fertilizer should be flexibly determined according to tree age and local practices. Newly harvested pear trees can be fertilized by opening a ring-shaped trench, or by opening radial trenches following the direction of the root system, or by opening strip trenches between the rows of pear trees, or by digging holes. These methods should be alternated from year to year. To reduce fertilizer waste, fertilizer should be applied deeply, at a depth of 30-50 cm. In case of drought, irrigate promptly so that water can regulate fertilizer availability. Sun Ting
