1. Site selection: Choose a place with deep soil, fertile soil, and strong water and fertilizer retention capacity as a planting site. 2. Digging: Dig planting trenches. Keep the row spacing at 0.8-1 meters during manual planting and 1.25-1.3 meters during mechanized planting. The trench depth and width can be kept at 25-30 cm. 3. Sowing: Choose plants with thick, upright stems as sugarcane seeds. The seeding rate can be determined according to the size of the stems. 4. Fertilization: Apply sufficient base fertilizer when sowing, and topdress pure nitrogen during the tillering and elongation stages. 5. Soil: Soil the seedlings once when they begin to tiller, at the peak of tillering, and at the initial stage of elongation.
1. Sugarcane planting method
1. Land selection
Choose fertile soil, deep soil (cultivation layer reaches 40-45 cm), flat terrain, Plant in a place with good air permeability and strong ability to retain water and fertilizer.
2. Ditching
(1) Dig planting ditches, and when carrying out artificial planting and harvesting, control the row spacing to 0.8-1 meters. When carrying out mechanized planting and harvesting, the row spacing should be controlled at 1.25-1.3 meters.
(2) The appropriate depth of the ditch is about 25-30 cm, and the appropriate width of the ditch bottom is about 25 cm.
3. Sowing
(1) Select plants with thick, upright stems and no flowers for seeding, and wait for them to be sun-dried, soaked and disinfected. , germination and other treatments before sowing.
(2) For small-stem species, the sowing rate is 10,000-12,000 buds/mu; for medium-stem species, the sowing rate is 8,000-10,000 buds/mu; for large-stem species, the sowing rate is 7,000-8,000 buds/mu. mu.
4. Fertilization
(1) When sowing, apply 1,000 kilograms of decomposed organic fertilizer, 100 kilograms of calcium magnesium phosphate fertilizer, and 30 kilograms of potassium chloride per mu. , 5-10 kg urea.
(2) During the tillering stage, apply 6-7 kg of pure nitrogen per mu.
(3) During the peak elongation period, apply 9-13 kg of pure nitrogen per mu.
5. Soil cultivation
(1) When the number of leaves of the seedlings reaches 6-7 (starting to tiller), soil should be cultivated once, and the soil cultivation height should be 3 About centimeters is appropriate.
(2) After entering the tillering period, carry out the second soil cultivation work. This time the soil cultivation height should reach about 6 cm.
(3) After entering the early stage of elongation, carry out the third soiling work. This time the soiling height should reach 20-30 cm.
6. Management
(1) Germination period: The appropriate germination temperature is 26-32°C, and the optimal temperature for cane root germination is 20-27°C. It is appropriate that the moisture content in the soil is 25%.
(2) Seedling stage: Ensure that the minimum temperature is not lower than 15°C and the soil moisture content is controlled at 20-30°C.
(3) Tillering stage: Ensure that the minimum temperature is not lower than 20°C (when the temperature is suitable, the tillering speed of the plant will speed up as the temperature increases, reaching the peak of tillering at 30°C), the moisture in the soil The content should be about 70% of the field water capacity.
(4) Elongation period: The suitable temperature is 30°C, and the moisture content in the soil is approximately 80% of the field water capacity.
2. Which areas are suitable for planting sugarcane?
1. Suitable planting areas
(1) Sugarcane is suitable for planting in areas with sufficient sunshine and In places with fertile soil and large temperature differences between winter and summer, it can be planted in southern tropical areas such as Guangdong, Hainan, Sichuan, Yunnan, Guangxi, Taiwan, and Fujian in my country.
(2) Sugarcane is mainly distributed from 33° north latitude to 30° south latitude, and the 25° north and south latitudes are concentrated planting areas.
2. Planting time
(1) Spring sugarcane: can be planted from January to April every year.
(2) Summer sugarcane: can be planted in May-June every year.
(3) Autumn sugarcane: It can be planted from the beginning of autumn to before frost, and can be harvested from November to December of the following year.
(4) Winter sugarcane: can be planted from the beginning of winter to the beginning of spring, the specific time is from November to January of the following year.
(5) Ratoon sugarcane: After the previous crop of sugarcane is harvested, the side buds of the sugarcane left in the ground naturally germinate and are then cultivated and managed.
