Sprinkler Irrigation for Tuber Crops and Application of PY50 Oscillating Sprinkler

Tuber crops are highly sensitive to both excess and insufficient water. Improper irrigation may lead to deformed tubers, fungal diseases, and even total crop failure. Stable humidity is required during critical growth stages, while humidity should be reduced before harvest to promote ripening.

Sprinkler irrigation is suitable for tuber‑growing fields with open or rugged terrain. In the early growth stage, the PY50 oscillating sprinkler can quickly cover large farmlands and efficiently supply water over wide areas for seedlings. When using the PY50 oscillating sprinkler, strictly control irrigation duration and water volume to avoid waterlogging and soil erosion.

Tuber bulking is the most critical and sensitive stage. Minimize the use of the PY50 oscillating sprinkler to prevent prolonged high leaf moisture that triggers fungal diseases. During the crop maturation stage, irrigation should be reduced. Even if the PY50 oscillating sprinkler is used, only short‑duration, minimal water application is allowed; heavy sprinkling must be avoided.

Traditional furrow irrigation has low water‑use efficiency and tends to cause root waterlogging, making it unsuitable for tuber crops. When combining sprinkler irrigation with the PY50 oscillating sprinkler, adjust operating frequency and water output according to different tuber growth stages to lower disease risks.
