Liyuan winter irrigation should be timely

Pear garden should be timely winter irrigation. Winter irrigation is carried out after the fruit is harvested and before the soil is frozen. However, it is the best period when the average ground temperature is 5°C and the air temperature is 3°C in a 5 cm soil layer.

It is advisable that the amount of water poured into the ground be the same as the amount of water on the day after irrigation. The water seeps into the root distribution layer, ie the young trees penetrate 20 to 60 centimeters, the adult trees seep to 70 to 100 centimeters, and the soil moisture maintains 60% to 80% of the large water holding capacity in the field.

In orchards with sufficient water sources and well-watered irrigation facilities, it is possible to use barren irrigation or ring-shaped furrow irrigation methods; in an orchard with poor water resources and poor conditions, discoid soil can be re-irrigated around the circumference of the tree canopy; in orchards with drip and sprinkling conditions, drip irrigation is used. And spray irrigation effect is good. Http://
