The sowing time of sugarcane in the main producing areas in China is from the end of 10 to the middle of March, early in the south and late in the north, but not later than the middle of April, and harvested from May to the middle of July. It is advisable to sow in autumn from the end of August to the end of September and harvest in mid-February.

Second, the planting technology of sugarcane

1, deep ploughing: two plows and two rakes are needed for planting machine, the depth is 50 cm, the soil should be loose and the depth of sugarcane planting ditch should reach 30 cm.

2. Shallow planting: The depth of sugarcane seeds returning to the soil is generally about 5 cm.

3. Wide row: The row spacing of sugarcane planting should be 90- 100 cm, which is beneficial to ventilation and field management after planting.

4. Close planting: 5-6 sugarcane seeds are sown in the sugarcane planting ditch every 100cm, and 3,000-3,500 double-bud sugarcane seeds are sown per mu.

5. Sufficient base fertilizer: per mu1000-2,000 kg farmyard manure. Mix 100 kg of calcium superphosphate, 25 kg of urea and 15 kg of potassium chloride for 7- 15 days, and then apply them in sugarcane planting ditch.

6. Seed soaking: Choose full, pest-free and damage-free double-bud seedlings, and soak the seeds with clear water or 2% lime water for 1-2 days, which can improve the drought resistance of sugarcane seeds and eliminate pests and diseases.

7. Planting method: Sugarcane seeds should be laid flat in the planting ditch with buds on both sides. When returning to the soil to cover the seeds, the seedlings should be lightly pressed into the soil before returning to the soil to facilitate rooting.

8. Prevention and control of underground pests: When planting, apply 2-3 kilograms of Mi Le per mu to prevent the harm of underground scorpions and sugarcane borers.

9. Chemical weeding before germination: Before planting sugarcane seedlings, use 25 ml of 40% atrazine and 200 ml of formamidine per mu, add 50-60 kg of water, and spray topsoil to control weed growth.

Common sugarcane pests and their control methods;

1, agricultural control: fitness cultivation, reasonable close planting and scientific management of fertilization are mainly adopted. Sugarcane shoot tips with thick and uniform stems without cracks and wormholes are selected as seeds. Planting ditch spacing 1.20 cm, ditch depth over 40 cm, ditch bottom width of 20 cm, planting about 20 buds per meter. Ensure that there are not less than 4500 effective stems per mu. During the growth period, the dead seedlings should be removed in time, the dead branches should be burned centrally, and the larvae in the stems should be killed by injection or acupuncture.

2. Physical prevention and control: using the phototaxis of adults, install frequency vibration insecticidal lamps to trap and kill adults.

3. Chemical prevention and control: seize the peak period (March-April, June-July, 9-65438+ 10) and prevent and control the occurrence.
