The spring management technology of ratoon cane
Sugar cane is not difficult to plant, but it is not easy to grow well. If you want to use low input and produce high yields, you need to talk about science. The following is combined with the common problems of sugarcane planters in sugarcane planting and the characteristics of sugarcane growth. Here are some technical suggestions for reference. First, the use of phosphate fertilizer must be fully pulverized with waste fertilizer or farm soil miscellaneous fertilizer mixed after stacking. In recent years, many sugarcane farmers have directly sputtered phosphate fertilizers in the ditch. In this way, the utilization rate of phosphate fertilizers is less than 10%, and more than 90% of them are fixed in the soil as ineffective phosphorus. The author's suggestion: 30-50 kilograms of phosphate fertilizer per acre is fully crushed, mixed with mixed fertilizers for farmland, and 15 litters of waste fertilizer are applied to open channels when planting sugarcane, so that the utilization rate of phosphate fertilizer can be increased exponentially. Second, control of pests Aphids, aphids, thrips, turtle turtles, etc. have become the main pests affecting sugarcane. It is suggested that when the cane is planted, it can be used after mussel furan-3-3.5 kg or 5% phoxim granules 10 kg or 14% chlorpyrifos granules 0.8-1.5 kg. But do not use tert-butyl phosphate, this kind of pesticide country prohibits the use on the sugarcane, the application of tert-phosphorus pesticides on sugarcane can easily cause human and animal poisoning, and the control effect is not ideal. Third, soaking the next species that is in the new open planting ditch wet or after the wet seed, seedlings soaked and sterilized before planting, with 50% carbendazim 1000 times liquid leaching 10-15 minutes, garbage fertilizer or soil miscellaneous Fertilizer application. Fourth, a variety of double bud seedlings cut off the sugarcane species in addition to the young end of the use of multiple buds, the general must be cut into two buds. Because the multi-bud seedlings sprout at most two strong buds, cutting off the sugarcane seedlings too long will cause waste of cane seedlings and lack of germination. Fifth, the spring management of ratoon cane Hexagon cane to high yield, scientific management in the spring is very important. l. Clean up the sugarcane garden as soon as possible after the early clearing of the park and the ridge loose soil to cut the cane, and clean the cane leaves to the cane ditch. Then break the ridge to bury the sugarcane leaves. Early ridge ridges can not only reduce the overwintering source but also facilitate the germination of the sprouts. 2, early fertilization, application of fertilizer before the combination of ridges Mushi phosphate fertilizer 40-50 kg, farm soil miscellaneous fertilizer or, waste fertilizer 1500 kg (phosphorus fertilizer should be fully crushed and mixed with soil miscellaneous fertilizer before application), urea 15 kg, Potassium chloride 10 kilograms, compound fertilizer 15 kilograms, ridge cover soil after application. 3, early prevention and control of insect pests and harmful toxins (1) pests: when ridged furan 4 kg per mu or 5% phoxim granules 10 kg or 14% chlorpyrifos granules 0.8-1.5 kg. (2) Chemical weeding: Weed herb application period is 96% Jindul 50-70ml, or 50% atrazine 250g plus 50% acetochlor 150g or 72% dole 120-150ml or Atrazine 250 g plus dimethyl tetrachlorohydrin 50 g water 60-75 kg spray. The weed seedling stage was sprayed with 500 g of enemy dioxins plus 100 g of dimethyl tetrachlorohydrin and 60-75 kg of water. 4, early check seedlings make up the seedlings should be carried out when Qimiao, where every 30 cm above the lack of buds should be replanting seedlings. Supplementing the seedlings should be carried out immediately after the rain.
