The use of phosphate fertilizer in sugarcane spring management technology: it must be used after sufficient farmland soil and miscellaneous fertilizer are mixed and fermented. Many sugarcane farmers immediately spread phosphorus and potassium fertilizer in the pit, so the utilization rate of phosphorus and potassium fertilizer is less than 10%, and more than 90% is consumed by ineffective phosphorus caused by soil immobilization. 1 mu is fully crushed with 30-50kg of phosphorus and potassium fertilizer, and then before planting sugarcane, farmyard soil cake fertilizer and waste fertilizer are mixed on15t, which can double the utilization rate of phosphorus fertilizer.

Pest control: borers, aphids, thrips and sugarcane turtles have become the key pests affecting sugarcane. When planting sugarcane, it is suggested to apply carbofuran 3-3.5 kg or 5% phoxim tablets 10 kg or chlorpyrifos tablets 14% 0.8- 1.5 kg per mu after ditching.

Sow the seeds wet, that is, sow the seeds when the ditch of the new species is wet or after wetting, sow them after wetting, disinfect and sterilize them, soak them in 50% triadimefon 10- 15 minutes, and apply them when the waste fertilizer or soil cake fertilizer is wet. When cutting sugarcane seeds with a variety of double-bud seedlings, except tender shoots and tender shoots, they are generally cut into double-bud seedlings. Because the number of multi-bud seedlings is at most two strong buds, cutting sugarcane seeds too long will lead to sugarcane seed consumption and insufficient buds.

Management of perennial sugarcane in spring Clear the Garden Friendship Clear the Garden, clear the sugarcane garden as soon as possible, put the sugarcane in Qing Ye to the sugarcane ditch, and then break the ridge and bury the sugarcane leaves. Clearing the garden and ridges can not only reduce the source of winter insects, but also help sugarcane buds germinate. Apply sufficient fertilizer before fertilization, and apply 40-50kg of phosphorus and potassium fertilizer per mu. Before application, fully crush1.500kg of farm soil cake fertilizer or waste fertilizer and mix with soil cake fertilizer. After application, cover the soil with urea solution15kg, potassium chloride10kg and compound fertilizer15kg, and ridging.

Control pests and weeds as soon as possible: 4 kg carbofuran or 0.8-65,438+0.5 kg 5% phoxim tablets or 65,438+04% chlorpyrifos tablets should be used for ridge closure. Organic chemical weeding: use 50-70ml of 96% Jinduoer to accelerate germination, or use 250g of 50% atrazine plus 50% acetochlor150g or 72% dole120-150ml or 250g of atrazine plus 50g of dimethyl carbon tetrachloride plus 60. Spraying weeds with 500g of dichlorvos, 0/00g of dimethyl carbon tetrachloride/KLOC-and 60-75kg of water at seedling stage. When the seedlings are in full bloom, early seedling inspection and replanting should be carried out, and the seedlings should be replanted at the place where there is no bud more than 30 cm apart, and replanted in time after the rain.
