Abstract
A method for promoting germination of underground buds and growth of new-born root systems of ratoon sugarcane is to cut stubbles based on a depth survey of the stubbles of the ratoon sugarcane, particularly including steps of: for a ratoon sugarcane field after mechanical harvesting, cutting the stubbles with a sugarcane stubble cutting machine, and remaining underground stubbles of 5-7 cm after cutting; for a ratoon sugarcane field with manual harvesting, cutting the sugarcane with a hoe, and remaining underground stubbles of 10-12 cm after cutting, so as to realize sugarcane cutting and stubble cutting in one step; thereafter, applying fertilizers and pesticides, and hilling up, wherein the underground buds of the stubbles are controlled to be distributed 10-15 cm below ground after hilling up; and finally conducting whole film mulching. The present invention is advanced and practical, and easily used and promoted.
