The farmer cultivated his fields just before planting time.

在种植前，农民先要耕地。

So, before planting, it is important to loosen the soil.

因此，在种植之前，松土是很重要的。

We used the wild sunflowers as green manure before planting our corn crop.

在种植玉米之前，我们用野生向日葵作为绿肥。

If you start growing sunflower from seeds, put them in room-temperature water for 2-8 hours before planting to start the growing process.

如果你从向日葵种子开始种植，在开始种植过程前把它们放在室温水中2-8小时。

In areas with cold winters, plant the seeds directly into the garden in autumn; in warm climates, keep them very cold for a week before planting outside.

在冬季寒冷的地区，秋天直接把种子种在花园里;在室外种植之前，要让它们保持一个星期的低温。
