Sugarcane starts to grow from the beginning of jointing and the cane stalk grows at an average of 3cm per ten days until the elongation basically stops. It is also the golden season for sugarcane to grow up. Doing a good job in field management is the key to winning a bumper harvest. Therefore, we must do a good job of the following measures: First, re-appropriate attack stem fertilizer sugarcane extension period is to send large roots, open large leaves, stems need to grow up when the most nutrients, the amount of fertilizer absorption of total fertilizer absorption of more than 50%. Therefore, it is necessary to re-attack the stem fertilizer, and the main application of nitrogen fertilizer to promote cane stem growth and thickening, prevent premature aging, increase production and sugar. Every 667 m2 (1 mu) applies 10-13 kilograms of urea, 250,000 to 3,000 kilograms of human fecal urine, and 25 kilograms of cake, such as base fertilizer and insufficient early phosphorus and potassium fertilizers, which can be combined with supplemental phosphorus and potash fertilizers. If the sugarcane plant grows vigorously and the leaf color is dark green, it can be applied less; Poor growth, premature yellowing or premature senescence, should be applied early. Second, high-Pei soil anti-loft During the elongation of sugar cane, should be combined with fertilization for high soil. Soil cultivation can not only preserve fertilizer and improve fertilizer efficiency, but also promote the development of sugarcane root system and prevent lodging. The specific approach is: through a number of thin soil, to achieve high soil, each soil cover only the first section of the cane, so that the roots of the cane head rooting, conducive to the growth of sugar cane. In high soils, we must also pay attention to border management, such as adding fertilizers and soils to the borders to prevent humans and animals from trampling in order to overcome the phenomenon of eliminating borders. III. Peeling old pests In the field, sugar cane field permeability is one of the important conditions for the growth of sugarcane. Sugarcane enters the late growth stage and a new leaf is grown every 7 to 10 days. Therefore, it is necessary to peel off the leaves of the foot and the yellow old leaves to enhance the ventilation and light transmission in the sugarcane field, promote photosynthesis, strengthen the stems, increase lodging resistance, increase sugar content, and also help control pests and diseases, reduce damage, and increase the yield of sugar cane. Sugar cane can feed cattle or fuel. Fourth, irrigation Drought and strong stems 8 to September sugar cane into the jointing fierce long-term, in the case of good water and fertilizer conditions, can grow 3 to 3.5 centimeters a day, each month can grow 80 to 90 cm high, so pay attention to irrigation . In particular, when drought occurs, water should be promptly irrigated, and soil moisture content should be maintained at 60% to 80%. Hilly slopes should be sealed and ridged heads should be set up to fight for rain and water. In addition, the old leaf or mulch can be used to cover the cane pods, and the cash crops can also be interplanted to increase the mulch cover and reduce the evaporation of soil moisture. Conditional irrigation should be used to avoid drought and reduce production. Where there is water, we must fill the water without losing our time to ensure a good harvest of sugarcane. V. Prevention of Pests and Diseases Harvest from August to September is both a long season of sugar cane jointing and a period of various pests and diseases. For example, in July, the cockroaches and locusts, and beetles and filarial insects from August to September, especially the roots of filarial food cane, will cause sugarcane to wither and fall down. Control measures: According to the pest situation, timely application of pesticides. For the dry sugarcane fields, the application of carbofuran 1.5 to 3 kg per 667 m 2 kills both ants and cockroaches, and also kills underground pests such as ground tigers, beetles and filarial bugs.
