Sugarcane has a long growth period and requires a large amount of fertilizer. According to studies, each can form one ton of raw sugar cane to absorb nitrogen (N) 1.5 to 2? from the soil, phosphorus (P2O5) 1 to 1.5?, and potassium oxide (K2O) 2 to 2.5?, Calcium oxide (CaO) 0.5 ~ 0.75?.
In the growing process of sugarcane, different fertilizer requirements are different at different times. The total fertilizer absorption law is roughly "two less, more in the middle," that is, in the seedling stage, the need for fertilizer is eager to cut and less absorption, the demand for nitrogen Slightly more, phosphorus, potassium followed; in the stage of tillering, the amount of fertilizer needed gradually increased, and the absorption of three elements accounted for about 10% to 20% of the whole period; when it entered the extension period, the absorption of three elements increased greatly. It accounts for more than 50% of the whole period. At this time, high temperature, heavy rain, and strong light season, the utilization of light energy and nutrients is the highest in sugarcane, and it is the key fertilization period. After the mature period, the amount of fertilizer needed by sugarcane gradually decreases.
According to the nutritional requirements and characteristics of sugarcane, high-yield cultivation and fertilization should be based on the principle of “combination of nutrition and growth requirements, combination of organic and inorganic fertilizers, and combination of long- and slow-acting fertilizersâ€.
1. Pay attention to the application of organic fertilizer and create conditions to open up organic fertilizer sources.
In sugar cane cultivation, manure and cooked compost are all good organic fertilizers. Organic manure should be used as base fertilizer. Generally, 1500 m should be used in the mu and applied on both sides of the seedlings or on the seedlings. Then the fertilizer is applied to the heap fertilizer. Covered with soil. Conditioned sugarcane fields should actively intercropping green manure and leguminous crops in the sugarcane field, and be used together with chemical fertilizers in the sugarcane topdressing.
2, according to the characteristics of sugarcane growth period, nitrogen, phosphorus, potash fertilizer application, Shizujifei, pay attention to attacking stem fertilizer, Shi Shi tail fertilizer.
Applying basal fertilizer, when growing sugar cane, apply 20-30% of total nitrogen, 60-80% of phosphate fertilizer, and 60-80% of total base fertilizer (potassium) and potash fertilizer as base fertilizer. On seedlings, cover soil again.
Re-apply for stem fertilizer, end of May, early June, the onset of the rainy season, sugar cane jointing, the use of more than 60% of the whole growth period of nitrogen fertilizer and 20% to 40% of phosphate fertilizer, mixed evenly applied to the base of the cane, large earth.
Supplement Shi Shi Tail fertilizer, sugarcane growth cycle is long, the amount of fertilizer required, easy to deferrable late, in order to ensure that the late premature aging and the next year perennial root cane bud nutrition, should be in late August, timely supplement Shi strong tail fertilizer, generally Use available nitrogen fertilizer.
The above fertilization techniques are for reference only. In actual production, fertilizers should be applied in time according to the growth of sugarcane. In short, as long as we carefully follow the laws of sugarcane growth, fertilization due to soil causes a good yield increase.
Many essential vitamins are needed in the diet every day. The fruit body of mushrooms is an excellent source of B-complex vitamins, including riboflavin (B2), nicotinic acid, pantothenic acid, thiamine (B1) biotin, folic acid, and vitamin B12. Mushrooms are a particularly rich source of riboflavin. And mushrooms are one of the best non-animal sources of niacin: 100 grams of fresh mushrooms provide more than a quarter of the vitamins an adult needs daily.
