Drought resistance technology of sugarcane

Drought-resistant and high-yielding varieties such as Taiyou and NTSC 25 were selected. Mechanical deep ploughing deep pine with high horsepower tractor deep ploughing deep pine 35-45 cm, can increase water storage after rain, water is not easy to evaporate. Planting with deep trench and flat bottom, the soil should be finely crushed to enhance the soil water retention capacity and facilitate the growth of sugarcane roots and the germination of sugarcane buds. Planting water conservation technology 1. Apply more organic fertilizer. two。 Use fresh seed stem or multi-bud segment seed stem, soak the seeds and disinfect them, and sprinkle the seeds properly after planting. 3. The technique of peeling leaf (sheath) of sugarcane tip (tail) without cutting seed was adopted. 4. Newly planted sugarcane is planted after planting ditch to cover soil to cover sugarcane species. Comprehensive drought relief measures 1. "three wet" (wet seedlings, wet fertilizers, wet planting ditches), ploughing and loosening the soil after rain, sealing the ditches and storing water. two。 Planting in autumn and winter, early management of fertilization and early closure of rows to prevent the loss of water on the ground. 3. Covered with plastic film or sugarcane leaves. 4. Expand the application area of sugarcane planting technology by spraying alcohol waste liquid. 5. Reasonable interplanting. 6. The field is seriously short of seedlings, and the area can be reduced by combining ridges.
