Six points of sugarcane can be planted in winter with high yield.

Planting sugarcane in winter can not only be high-yielding, early-maturing, but also stagger in farming season, it is easy to arrange land stubble, sugarcane species are also easy to solve, and the yield per 667 square meters is 5% higher than that of spring-planted sugarcane. The main results are as follows: 1. The land with deep soil layer, middle and upper fertility, loose soil and strong water retention should be selected for soil preparation. After deep ploughing and fine raking, the planting ditch should be opened according to the row spacing of 90cm and 100cm. The ditch depth is generally about 15cm, and the bottom of the ditch should be fine and flat, in order to improve the germination rate of seed stubble. 2. Disinfect and select the sturdy sugarcane at the tip (sugarcane tail), cut into 2 or 3 bud segments with a sharp knife, and soak the seeds with 50% carbendazim or topiramine 800-1000 times solution for 10 minutes to prevent the incision from being infected with pineapple disease and black rot. 3. Sugarcane planting can be divided into early winter planting, middle winter planting and late winter planting, early winter planting starts from the middle of November, and late winter planting can be postponed to the last ten days of January of the following year. According to the characteristics of the local climate, the sowing date is selected according to local conditions, and it is generally better to plant in early winter. 4. After planting sugarcane and sowing in Guandong, 60 piculs of rotten farm manure or high-quality soil miscellaneous fertilizer are applied every 667 square meters, mixed with 25 kilograms of superphosphate and 10 kilograms of potassium chloride fertilizer, and then drenched with 1520 piculs of dung water. Finally, the soil is covered with 4cm soil to increase temperature and keep moisture. 5. The method of plastic film mulching should be adopted to increase the temperature and humidity and improve the germination rate of sugarcane. The plastic film should be 40-45 cm wide, sow, fertilize and cover the soil when the soil moisture is sufficient, and cover the top of the seedlings when covering the film, so that the film is close to the surface, and the four sides are pressed with soil. If there are holes in the plastic film, it is necessary to bury it with fine soil. 6. Planting sugarcane in Guandong is vulnerable to the damage of sugarcane Chilo suppressalis, resulting in withered heart and dead seedlings. After the spring is warm next year, uncover the film to refine the seedlings, combined with weeding and fertilization in the middle of ploughing, spray it with 250ml of 18% Shachongshuang and 30kg of water for every 667 square meters and spray it after breakfast or evening on a sunny day.
