Black-skinned sugarcane planted in rice fields is called paste sugarcane.
Black-skinned sugarcane planting: sugarcane planting in the field does not start from seeds, and sugarcane seedlings are generally planted directly. There are many sources of sugarcane seedlings, mainly sugarcane stems, because buds will grow on sugarcane nodes. The method is to take the whole sugarcane stem, cut it into two-bud seedling segments, and then plant it horizontally or obliquely. In order to save labor, the whole plant is also planted flat. When the labor force is sufficient in the early stage, it is advisable to use two double-bud seedlings or three-bud seedlings at the top of the raw material stem to be harvested. This method can only be used for spring sowing or first post. Others include tillering seedlings and various lateral buds. In addition, the perennial root method can also be used, that is, when harvesting raw sugarcane, the sugarcane head is not dug, and the roots can be cut and drained for fertilization after harvesting.
In the rotation system, it is usually new planting, followed by the second or third regeneration, the second or second rice, and then back to the new planting. But before the late rice harvest, the newly planted sugarcane is planted in the paste soil between rice plants, which is called paste sugarcane. Its advantage is that it will not affect the growth of rice, and it can also make sugarcane grow ahead of time, saving operating expenses such as land preparation and border construction.
