开拓 (kāi tuò): เพื่อทําลายพื้นดินใหม่ (สําหรับการเกษตร)

In order to increase grain production, the villagers decided to cultivate this wasteland and open up new farmland.

The government encourages farmers to open up terraced fields in mountainous areas, plant cash crops, and increase their income.

This agricultural company plans to open up an oasis at the edge of the desert to grow drought-resistant crops.

After several years of effort, they finally opened up this saline-alkali land into fertile rice fields.

Agricultural experts suggest that when opening up new farmland, attention should be paid to protecting the ecological environment, and forests should not be cut down blindly.
