Sugarcane is a Gramineae sugarcane plant, which is native to tropical and subtropical regions. Sugarcane is a plant with high photosynthetic efficiency, high light saturation point, low carbon dioxide compensation point, low photorespiration rate and high photosynthetic intensity, so sugarcane has high biological yield and great income. Sugarcane is the main raw material for sugar production in China. \x0d\ Newly planted sugarcane is propagated by planting sugarcane seedlings. Soon after planting, it took root and sprouted, growing many tender buds and forming clusters. When harvesting, only the sugarcane stems are harvested, and the roots remain in the soil, that is, the perennial roots, and the perennial roots re-branch to grow stems in the second year; Therefore, sugarcane is a perennial plant, and its harvest can reach 7-8 times, which is usually 3 times in China, that is, after three years, the perennial roots are dug out and planted again. \x0d\ Sugarcane seedlings and perennial roots: Sugarcane seedlings are planted directly in the field, not from seeds. 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. Recently, in order to save labor, the whole plant has also been 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 chopping 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. \x0d\ Planting period of sugarcane: The growing period of sugarcane is mainly affected by mild climate and varieties, which is about 14 ~ 18 months in Taiwan Province Province, but the ratoon can be shortened to only 12 months. Sugarcane with insufficient growth period not only has low yield, but also low sugar content. Autumn planting sugarcane is in August and September, and spring planting sugarcane is in February and March. Because sugar production starts from 1 1 month to April of the following year, autumn planting sugarcane has enough growth period, while spring planting sugarcane needs to be delayed to cooperate. \x0d\ Intercropping sugarcane: Unfortunately, young sugarcane grows slowly and the land is not fully utilized. At this time, other short-term crops can be intercropped with sugarcane seedlings and harvested before sugarcane growth to increase land income. However, there is one condition to be observed, that is, intercropping crops cannot have too many adverse effects on sugarcane planting. Suitable crops are sweet potatoes, peanuts, beans, corn, tomatoes, garlic, potatoes, melon seeds and watermelons. \x0d\ Paste sugarcane: In the rotation system, it is generally newly planted, followed by second and third crops of perennial roots, first and second crops of rice, and then newly planted. 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. Intercropping with first-stage rice is called first-stage cream cane, also called spring planting cream cane. Intercropping with second-stage rice is called second-stage paste sugarcane, also called autumn planting paste sugarcane. \x0d\ Sugarcane green manure: In the newly planted sugarcane field in autumn, green manure can be planted in the leisure time after the previous harvest, and ploughed into the soil before planting sugarcane to supplement the organic fertilizer in the soil. Common green manure crops are hemp, sesbania and Tiger Claw bean. \x0d\ Sugarcane diseases: white leaf disease, _ stripe disease, leaf blight, etc. As long as you are sick, no matter what the disease is, there is no cure. I can only pull out the whole plant, burn it, and pray well, hoping it won't spread. This requires frequent inspection, early detection and quick eradication. The better control method is to cultivate disease-resistant varieties, not afraid of virus attack.
