Sugar cane is a more important sugar crop, especially in areas with fertile soil, adequate sunlight and high winter and summer temperatures. Sugar produced from sugar cane accounts for 80 per cent of our total sugar production. The high economic value of sugar cane has become an important cash crop for income generation for a wide range of farmers ' friends. The guangxi magnificent autonomous region is one of the main sugar cane-growing areas of the country, and the large-scale expansion of sugar cane-growing technology in guangxi will certainly ensure that farmers and friends will gain more revenue. Details are as follows:
I. Selection of quality varieties
The choice of good-quality sugar cane seeds is currently the best way to increase the production of sugar cane, and each place should choose a good species that is adaptable, resilient and grounded in its own conditions. In chinzhou, several sugar cane varieties have been selected for comparative testing, showing that: sugar 00 00/236, sugar 42 is highly resistant, has a high incidence of tubing, has a high incidence of seeding and is ready to grow at an early age. If harvest can be taken in the middle of the dry season, economic profits will be greatly increased and the value of expansion will be higher; sugar 43, sugar 93/159, and willow city 07-58, although they are average, are good in sugar, cane production, resistance, and have a medium-to-high rate, and a medium-to-duperity rate and a medium-to-breed species; sugar 29, willang city 05/136, sugar production, resistance, etc., are common and easily subject to foliosis, which is not suitable for large-scale extension in the west。
Ii. Deep-farmed sugar cane and re-applied base fertilizer
There are usually two types of deep-drop farming, namely cattle ploughing and mechanical plowing. Among them, the depth of the plough should not exceed 35-45 cm, and the impact of the pine soil could be achieved by using hard-earth fragmentationrs; if ploughing was used, the depth of ploughing should not exceed 30 cm, and the soil could be dredged with two ploughs. At the same time, attention must be paid to the rational application of base fertilizers, including phosphorus, potassium and organic fertilizers, which, of course, are still the most important. Fertilization is determined in the context of the soil, but normally the application of calcium phosphate is not appropriate to exceed 10-15 kg/667m2, the application of fertilizers in mature farmers is not appropriate to exceed 1,000-1500 kg/667m2, and the application of potassium sulphate is not appropriate to exceed 10-15 kg/667m2, and is applied evenly。
Iii. Deliberate seeding, leaching
3. 1 careful selection of seeds
It is important to choose the cane, which is big, full and free of disease, and to cut the cane, with a knife, into single, double, multi-sprouts, etc., regardless of the type。
3. 2 irritation
Sterilization can significantly enhance the water-absorption performance of seedlings and eliminate some residual pests from seedlings, with better results. Vaccination, limewater, and pharmaceutical impregnation are common methods, but the choice of different impregnation methods means that the leaching times will vary, but generally do not exceed 2 h, which otherwise poses a significant risk to seedlings。
Iv. Field management
4. 1 following fertile ground
When sugar cane grows to four to six leaves, it begins to be bred, and 667 m2 sugar cane is used to apply compound fertilizer (at 25% concentration) of 50 kg, 20 kg potassium fertilizer, and 20 kg urea, which is then mixed and distributed. In general, sugar cane cane is not expected to last longer than the end of june, usually in may-june。
4. 2 prevention and control of pests and diseases
Sugar cane has more pests and diseases in its cultivation. The paper focuses on fungal disease, sugar cane black ear disease and two difficulties。
4. 2. 1 fungi conditions
The fungal disease is also known as the sugar cane pineapple disease, and once the sugar cane plant is infected with the fungus disease, the colours of the cut-off will change at both ends, red and black, resulting in a number of coal powders (black), and the seedlings of the cane will become empty shells over time. The method of combating fungal disease is impregnation, with 50 per cent of the fungus venom up to 1,000 times or 50 per cent of the fungus to impregnate 180 times; and water purification 1 d。
4. 2. 2 two difficult points
At two points, the emergence of sugar cane in the country's major sugar cane-producing areas, especially in the dry slopes, will seriously affect the growth of sugar cane. In order to deal effectively with the two difficulties, the first is small land production, the second is rational rotation with other crops, and the third is the promotion of early and spring cane farming techniques and winter cane farming techniques, taking into account local realities。
4. 2. 3 sugar cane black ear disease
The incidence of sugar cane cane cane disease is closely related to the disease and variety of sugar cane, which, if it spreads, will inevitably have a greater impact on sugar cane growth. In general, sugar cane cane is more likely to be diseased than new cane, and production losses are greater. In order to effectively combat sugar cane scavengers, the first is to plant seedlings in hot water at a temperature of 50°c, the second is to plant 120 s; the third is to use anti-disease varieties; and the third is to remove the strain of sugar cane scavengers if they are detected, and to centralize them as soon as possible, in order to avoid the spread of sugar cane scavengers。
