1, plastic trimming will be carried out in spring. When the stems and vines are covered with brown columns and the tips are about 20 cm beyond the brown columns, cut off the stems and tips of 2-3 of them by 40 cm. When new buds and leaves germinate after short cutting, the shoot tips of other plants are cut off. For potted plants whose whole plants or lower leaves fall off due to freezing in winter or other reasons, the stems and vines can be cut by half 1/2, and the other half by 2/3 or 3/4, so that the height of the cuttings is staggered, and the new leaves of rice growing under the cuttings can be quickly covered with brown columns.
