To do a good job in ratoon sugarcane cultivation, the following points should be followed:
Loosen the stumps early: after the sugarcane is harvested, open the furrows and loosen the soil at the Beginning of Spring solar term, cut away excessively tall cane stumps and autumn shoots, and make sure to hoe quickly without damaging the stumps, keep the stumps level, and leave no green visible at the field edges. Opening the furrows and loosening the soil can increase soil aeration, raise soil temperature, and help the sugarcane buds germinate.
Replant seedlings early: at the first irrigation after loosening the stumps, use sprouted seedlings or old stump seedlings to fill gaps and broken rows, strengthen management, and strive for a full stand. For replanted seedlings, strengthen fertilizer and water management, and apply extra fertilizer so that the new replanted seedlings catch up with the old seedlings.
Raise the seedlings early and earth up the stumps early: after the ratoon sugarcane has a full stand of seedlings, apply 20 jin of quick-acting nitrogen fertilizer, 100 jin of superphosphate, and 2000-3000 jin of farmyard manure per mu, then earth up the stumps and cover with soil.
Fertilize early and cultivate soil early: in May, when the sugarcane seedlings begin to joint, carry out intertillage, earthing up, and heavy pressing, and apply more than 50% of the total fertilizer amount at one time, which has a good effect on increasing the stalk-forming rate.
Control pests and diseases early and clean the field in time: cut down smut-infected seedlings and dead-heart seedlings early, spray pesticides early to control sugarcane borers and cotton aphids, and do not cut and leave stubble sugarcane on cloudy days. Based on the dead leaves in the harvested sugarcane field, clean the field while harvesting to eliminate residual pests and sources of disease.
