How to manage the growth of black sugarcane in the middle and later stage? The management goal of black-skinned sugarcane in the middle and later stage of growth is mainly to thicken and accumulate sugar in order to increase yield and improve quality. The specific technical measures are as follows: fertilization. The black-skinned sugarcane was fertilized every 15 days, mainly N-P-K complete fertilizer and K fertilizer, 50-60 kg N-P-K compound fertilizer and 20-30 kg potassium nitrate per mu, drenched with water, or sprinkled after rain, or irrigated with "horse race water" in the sugarcane field. Cultivate the earth. After fertilization, the thin soil in the border ditch is shoveled around the black sugarcane plant to thicken the topsoil layer, which can not only stabilize and strengthen the plant, prevent lodging, but also promote and protect new roots, enhance absorption function, and prevent soil water evaporation. reduce soil water loss and keep the soil moist. Store water. Black-skinned sugarcane needs a large amount of water in the middle and later stage of growth, so it is necessary to store more than 2/3 of clear water in the border ditch to ensure an adequate water supply so that black-skinned sugarcane can grow and develop normally. Foliar topdressing combined with hormone spraying. In the middle and later stages of black-skinned sugarcane growth, 1000-fold avermectin, 1000-fold acetamiprid, 1000-fold copper, 1000-fold KT-30, 1000-fold potassium nitrate, 1000-fold methamectin, 1000-fold imidacloprid, 1000-fold sugarcane disease, 1000-fold Miaole, 1000-fold natural brassine and 300x potassium dihydrogen phosphate must be sprayed every 15 days to thicken and accumulate sugar.
