Abstract

The invention relates to a high-efficiency ratoon sugarcane cultivation method and belongs to the technical field of agricultural high-yield culture. The method is technically characterized in that the variety with strong ratoon is utilized, the root shovel time avoids December to January of the next year, and the root shoveling is not performed when the soil temperature is lower than -2 DEG C; in a ratoon management period, fertilizers are applied twice in one growth period, the fertilizer nutrient proportion is N to P2O5 to K2O = 26 to 12 to 4 and N to P2O5 to K2O = 26 to 12 to 10, the early content of the K2O is 4%, and the later content of the K2O is increased to 10%; the sugarcane sugar can be improved by 15% or above. Compared with a traditional method, the high-efficiency ratoon sugarcane cultivation method can effectively save 4 labor workers for weeding, avoids chemical herbicide, reduces fertilizer application times, saves 2 to 4 workers for applied fertilizer, improves the sugarcane yield by 0.5 to 3 tons per mu and is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of agricultural high-yield cultivation, and in particular relates to a high-efficiency cultivation method of perennial root sugarcane. Background technique [0002] Sugarcane is a perennial root crop, and it can be harvested for 3-7 years once a new plant is properly managed. Planting sugarcane is one of the main means for farmers in the hot areas in southern my country to get rid of poverty and become rich. Perennial sugarcane management requires less labor, lower planting costs, early growth and rapid growth, and rapid growth in the early stage. The maturity period of the same variety is 20-30 days earlier than that of newly planted sugarcane. Today, it is beneficial for sugar companies to arrange sugarcane cutting, transportation and pressing more freely. In the actual production of sugarcane, due to improper management of perennial root cultivation, the yield of perennial sugarcane is reduced by 1-3 to...
