Where is the producing area of sugarcane in Guangxi?

Sugarcane producing areas in Guangxi are Bobai County, Guigang, Longzhou and so on. Among them, Bobai County is the largest black-skinned sugarcane production area in Guangxi. The black-skinned sugarcane is black and oily, and the meat is crisp and sweet. It is a famous overseas sugarcane variety.

Planting management of sugarcane:

1. Sugarcane fertilization

The growing period of sugarcane is long, the plant is tall and the yield is high. Therefore, in the whole growing period, the amount of fertilizer application is one of the main factors that determine the yield. Due to the large amount of fertilizer needed in sugarcane, fertilizer accounts for a large proportion in the cost of sugarcane production. Therefore, it is of great significance to master the fertilization technology correctly, to achieve timely and appropriate amount, and to meet the fertilizer needs of sugarcane to the maximum extent.

two。 Sugarcane irrigation and drainage

Sugarcane needs a lot of water in its lifetime, but it is not resistant to waterlogging. The general trend of water demand is "less at both ends and more in the middle". That is, the water requirement is less in the sprouting stage, tillering stage and mature stage, and high in the elongation stage. Therefore, sugarcane fields should be kept in a "moist-wet-moist" state respectively. The climate of Yunnan is dry in winter and spring and rainy in summer and autumn. Therefore, in the early stage of sugarcane growth, although there is little water demand, irrigation should be strengthened. The extension period coincides with the rainy season and generally does not need irrigation. More than 80% of sugarcane fields in Yunnan do not have irrigation conditions. Sugarcane is not resistant to waterlogging, and stagnant water in sugarcane fields will cause rotten roots and need to be drained in time.

3. Sugarcane weeding

Before sugarcane is closed, weeds are easy to grow and consume nutrients to cover sugarcane seedlings, so weeding in sugarcane fields should be carried out in time. Generally combined with ploughing and soil cultivation, it is carried out by manual operation. Commonly used herbicides are "simajin" and "atrazine". The soil surface is sprayed with 200-250 grams of water and 50-75 kilograms of water per mu before sugarcane emergence. The effect is good. The effect is as long as 3-4 months. Spraying once can solve the problem of weeds in the seedling stage.

Sugarcane is a kind of plant that likes temperature and light, so it is more suitable to be planted in Guangdong, Guangxi, Taiwan, Fujian, Sichuan, Yunnan, Jiangxi, Hunan, Guizhou, Zhejiang, Hainan and Hubei.
