Latest precautions for intercropping with pear trees, a full analysis of planting key points

Intercropping and relay intercropping are traditional planting models in our country, and with the continuous development of agriculture, this model has attracted the attention of many farmers and is widely used. Pear orchards are very suitable for intercropping, but when intercropping, some issues must also be noted, otherwise it will affect the growth and development of both crops. Below, let's take a look with the editor at the precautions for intercropping with pear trees.

1. Crops should not be tall

In pear orchards, it is not suitable to intercrop with tall crops such as corn and sorghum, as this will seriously affect the ventilation and light transmission of the pear trees. Pear trees are inherently light-loving fruit trees, and once there is insufficient light, their growth, development and yield will be affected. It is suitable to intercrop with short-stem crops such as beans, potatoes, peanuts and strawberries.

2. The growth period should not be too long

In pear orchards, it is not suitable to intercrop with crops that have too long a growth period, especially perennial crops, as this will affect fertilization and cultivation for the pear trees and have an adverse effect on their growth. It is suitable to reasonably intercrop with crops that have a relatively short symbiotic period with pear trees, such as rapeseed, garlic and green manure.

3. Not deep

Pear trees have a relatively developed root system and take root deeply, so intercropping should not be with crops that have developed root systems and take root deeply, to avoid competing with pear trees for water and nutrients. It is suitable to intercrop with crops that have shallow root distribution and an undeveloped main root, such as some vegetables. In addition, it is not suitable to intercrop with crops that consume relatively strong soil fertility, such as sugar beet.

4. Not close

In pear orchards, intercropping should not place crops right against the trunk or under the tree canopy, to avoid hindering the management of pear trees and affecting their growth. The intercropping distance should be as far away from the pear trees as possible, generally at least 50 cm beyond the vertical extent of the canopy, to ensure the normal growth of both pear trees and crops without interfering with each other.

5. Avoid intercropping with root-type medicinal herbs

Intercropping Chinese medicinal herbs in pear orchards can yield several times, or even dozens of times, more income than intercropping field crops, but not all Chinese medicinal herbs are suitable for intercropping. For example, root-type Chinese medicinal herbs not only have a long growth period, but also are very likely to cut the pear tree roots when being dug up.

6. Give priority to fruit

After intercropping, fertilizer and water management should be strengthened according to the cultivation of both pear trees and intercrops, but the principle of giving priority to fruit must always be adhered to. When conflicts arise between the growth of pear trees and the growth of intercrops, control measures should be taken for the intercrops to create conditions for the normal growth and development of the pear trees.
