The tutor teaches you to grow sugar cane
Guangxi Lvtai Agricultural Investment Co., Ltd. and the Institute of Tropical Biology, Chinese Academy of Tropical Agricultural Sciences jointly developed a high-tech agricultural project and established five sugarcane biochemical and virus-free healthy seed stalk cultivation bases in Guangxi, covering an area of ​​1,500 mu. The annual output of sugarcane can be detoxified. About 12,000 tons of stems. Huang Shizhong, the company's manager, introduced the company's sugar cane detoxification planting experience.
Firstly, land preparation is required, and the sequence of rotary tillage, deep plowing, rotary tilling, and ditching are performed in the order of 1.2 meters for trenching and 40 centimeters for planting. Then, Shiji Fei, which requires 10 kg of urea, 50 kg of superphosphate, 20 kg of potash, and 300 kg of bio-organic fertilizer for each acre, will need to put pesticides in the base fertilizer, and mix 2 kg of phoxim per acre (or 3 to 4 kg of carbofuran) and 2 kg of insecticidal double.
Planting and fertilizing in soil preparation also has a certain ordering requirement, such as ditching, planting, applying basal fertilizer, covering soil (covering 5-8 cm of cane stems), and covering film (white film, film width 60 cm). Before planting, the sugarcane seeds were cut into double-toothed cane stalks, soaked with the stem treatment agent for 20 minutes. After planting, the cane stalks were placed horizontally in the planting ditch. The spacing of the cane stalks was determined according to the variety. Guitang No. 29 was 50. ~55 cm, Liucheng 05136 is 45 cm, other species 37 cm. The urea, superphosphate, and potassium fertilizers of the basal fertilizer were evenly mixed and applied in the middle of two cane stalks. The bio-organic manure was applied directly to the surface of the cane, and then the soil was covered. The thickness of the cover soil is appropriate to cover 5~8 cm of the cane stalk, and the surface of the ditch is to be 50 cm wide and smooth so as to cover the membrane.
In addition, in irrigation, if drip irrigation is used, the drip tube should be laid under the membrane when the cover film is planted. After planting, there will generally be no disease. If smut occurs in the sugarcane field, one plant will be pulled out. At the time of childbirth, insect pests such as locusts may occur due to external influences, and spraying may be appropriately controlled depending on the circumstances. After the land is covered with a film, it is necessary to carefully seal once (her herbicide before germination). If weeds grow during the seedling stage, we must use a herbicide again. In top-dressing topdressing, according to the growth situation, the top-dressing stage (that is, when the main stem is jointed with about 3 knots) can be top-dressed, and can be formulated with 40 kg of urea, 30 kg of phosphate fertilizer, 30 kg of potash, and 2 kg of octanol per acre. Phosphorus (or 3 to 4 kg of carbofuran), 2 kg of dimehypo, cultivating soil after fertilization.
