Six measures to improve the high yield of sugarcane planted in winter

Planting sugarcane in Jinggu winter can not only have high yield, early maturity, but also stagger farming season, it is easy to arrange land stubble, sugarcane species are also easy to solve, and the yield per mu is 510% higher than that of sugarcane planted in spring. First, land preparation and customs clearance. It is appropriate to select the land with deep soil layer, middle and upper fertility, loose soil and strong water holding capacity. after deep ploughing and fine rake, the planting ditch should be opened according to the row spacing of 90-100 cm, the ditch depth is generally about 15 cm, and the bottom of the ditch should be fine and flat, so as to improve the germination rate of seed stubble. Second, disinfection. Select the stout sugarcane at the tip (sugarcane tail), cut it into 3 bud segments with a sharp knife, and soak the seeds with 50% carbendazim or Topurazin 800Mel 1000 times solution for 10 minutes to prevent the incision from being infected with pineapple disease and black rot. Third, suitable for broadcasting. Winter planting of sugarcane can be divided into three types: early winter planting, middle winter planting and late winter planting. Early winter planting begins in mid-November, while late winter planting can be postponed to late 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. Fourth, fertilization is off. After planting sugarcane in winter, 60 piculs of rotten farm manure or high quality soil manure were applied per mu, 25 kilograms of calcium superphosphate and 10 kilograms of potassium chloride were mixed as the cover of base fertilizer, and then drenched with 20 kilograms of dung water, and finally covered with soil 4-5 centimeters, in order to increase temperature and keep moisture. Fifth, cover the membrane off. Planting sugarcane in winter should adopt the method of plastic film mulching to increase temperature and humidity and improve germination rate. 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, and tighten 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 film, use fine soil to bury it. Sixth, kill insects. Planting sugarcane in winter is vulnerable to the damage of sugarcane Chilo suppressalis, resulting in dead seedlings. After the coming spring is warm, uncover the film to refine the seedlings, combined with ploughing, weeding and fertilization, with 18% insecticidal Shuang 250ml mixed with 30-50kg of water per mu, sprayed after breakfast or evening on a sunny day.
