Sugar cane is a common fruit for stems and a major raw material for the manufacture of sugar, which is widely cultivated. Sugar cane is suitable for planting in fertile soil, sunny, and large temperature difference between winter and summer. The following is a detailed introduction to sugarcane planting technology:
Sugarcane planting technology
1. Selection of land and machine cultivation: Sugarcane planting should choose convenient, deep, loose and fertile soil conditions to fully meet the needs of root growth, so that the root system can better play the role of absorbing water and nutrients. If the captain is sugar cane, first use the rotary tiller to break the cane head, so that not only the clods can be crushed, but also the sugar cane can be reduced. The cultivated land should be deep plowed with a large horsepower tractor, preferably 35-40 cm deep. The bottom of the ditch is 20 to 25 cm wide, and the soil after tillage should be finely divided and leveled.
2, line spacing and opening: If the water and fertilizer conditions are good, the line spacing can be appropriately increased, the line spacing is 1 meter to 1.2 meters; if it is a slope, you can choose small spacing planting, line spacing 0.8 meters to 1 meter is appropriate. The slopes should be parallel to the contour line, and the direction should not go down the slope, otherwise the rain will wash out the fertilizer and sugarcane.
3. Treatment of sugarcane: It is necessary to select high-yield, high-quality, disease-resistant, adaptable, and good-quality varieties. When selecting seeds, the sugarcane stems should be thick, uniform and crack-free, the sugarcane tips are thick, the leaves are broad green, and there are no pests. Seeding of sugarcane shoots, immersed in clear water or 2% lime water for 1-2 days, can improve the drought resistance of sugarcane varieties, and can also achieve the role of eliminating pests and diseases.
4, planting time: mastered from September of the year to February of the following year, there is no sugarcane species too early, too late to affect production and quality.
5. Reasonable close planting: The sugarcane seeds should be placed flat in the planting ditch, and the buds should be pressed to the sides. After the soil, it will be covered and compacted to facilitate the roots. Planting sugarcane ditch can be planted 5-6 per 100 cm. The sugarcane seed should be placed flat in the planting ditch, and the buds should be placed on both sides. When the soil is backed, the seedlings are gently pressed into the soil, and then the soil is covered and compacted. Eli hair roots. The row spacing of sugarcane planting is 90-100 cm, and the depth of sugarcane planting back cover is generally about 5 cm. The planting density is generally controlled at about 20 buds per 100 cm, ensuring an effective stem of 4,500-5,500 plants.
6. Field management:
(1) Fertilization: combined with the first weeding after emergence, 15 kg of urea is applied per mu. In the growing period, combined with each soil, 100 kg of calcium phosphate or calcium magnesium phosphate per acre, 10 kg of NPK fertilizer or potassium chloride. Apply foliar fertilizer and balanced fertilizer at the right time. During the growth period, the compound seedlings were sprayed with compound, high-efficiency, multi-element, organic ecological foliar fertilizer “Rongdafeng†300 times liquid 3-4 times; after the seedlings were planted, 5% carbon ammonium water was poured into the roots.
(2) Watering: The sugar cane needs a large amount of water. It should be timely flooded, but large water irrigation should be avoided, light water irrigation should be promoted, and the soil should be kept dry and wet, mainly moist.
(3) Temperature: Different growth temperatures of sugarcane require different temperatures, germination at 13 °C, normal germination at 20~25 °C, optimal temperature for germination 30~32 °C; sugarcane can grow slowly at 12~13 °C, elongation at 20~25 °C Gradually speed up, 30 ° C is the optimum temperature, growth slows above 34 ° C; below 0 ° C, sugar cane will suffer. During the ripening period of sugarcane, if the temperature in the early and middle period is higher than 20 °C, the temperature will gradually drop between 13 and 18 °C, the sugarcane is ripe and the sugar accumulation is good. If the early heat is insufficient and the temperature is lowered in the later stage, the sugarcane yield is low, including The sugar content is not high; if the mature temperature drops to around 0 °C, the sugar will be converted and decreased.
(4) Pediding seedlings: Generally, the soil should be 3-4 times per year, with an interval of about 30 days. At the same time, combined with the soil, timely seedlings, 7-8 seedlings per meter.
(5) Peeling leaves: After the sugarcane plant is stretched, the leaves are peeled off, and 3-4 leaves are peeled each time. Excessive stripping affects the growth of the plants, and the peeling leaves do not affect the powder in time.
(6) Disease prevention: The main pest in the sugarcane area is sugarcane borer, except for the application of pesticide granules of about 5 kg in addition to sugarcane and large soil; if the sugarcane heart leaves have a "flower leaf" phenomenon, use "insecticide double "300 times liquid spray on the heart of sugar cane to prevent the production of wind-breaking cane and dead-end cane.
(7) Harvest management: After the sugarcane is mature, cut it with a small sorghum and cut into the sugarcane field about 3 cm, which is conducive to the germination of the low bud of the cane. After the harvest of sugar cane or after the spring, it is necessary to clear the garden of the sugarcane in time.
Sugarcane planting considerations
1. Pay attention to fertilization. According to the characteristics of sugar cane in different growth stages, the principle of fertilization is: “Re-application of base fertilizer, timely and staged topdressingâ€. If only top dressing is applied, and no base fertilizer is applied, sugar cane is easy to grow: top-heavy, thick and thin, easy to fall. On the contrary, only the base fertilizer is applied, and no top dressing is applied, the stamina is insufficient, and the "rat tail cane" is formed, which affects the yield.
2, pay attention to waterproof: After April, gradually enter the rainy season, sugar cane planted in paddy fields, easy to accumulate water, resulting in poor soil ventilation, causing sugarcane rotten seeds and rot, so pay attention to the low-lying block of waterproof drainage work.
3, pay attention to weeding: generally after planting sugar cane and large soil after spraying a herbicide, with Atrazine 200 grams of acetochlor 150 grams of water 50 kg spray to seal the cane line.
