Winter rape plants are tall, grow long and require more fertilizer. Fertilizer should pay attention to the following points:
1. For every 100 kilograms of rapeseed, it is necessary to absorb 8.8-11.3 kg of nitrogen, 3-3.9 kg of phosphorus and 8.5-1.10 kg of potassium. According to the target yield, in combination with the difference in soil supply for good quality and cultivar, etc., it is necessary to determine the type, quantity, and application period of the fertilizer.
2. Rape base fertilizer is divided into base fertilizer and seed fertilizer. At the end of the fertilizer Mushi agricultural fertilizer about 3 tons, with the application of urea 11-16 kg or ammonium sulfate 25-27 kg (N fertilizer as a base thin fertilizer is generally accounted for 30% -50% of the total amount of nitrogen fertilizer), superphosphate 20-30 kg Potassium chloride 5-10 kg. Insufficient base fertilizer is compensated by seed fertilizers. Generally, human fecal urine and quick-acting phosphorus and potassium fertilizers are used for composting, and are often applied in rows or caves when sowing or transplanting rapeseed.
3, rape topdressing mainly used as Miaofei and manure. If the base fertilizer is lacking and the rapeseed grows poorly, the seedlings will be applied early and the number of top dressings will be appropriately increased. When rape seedlings 4-5 true leaf, internode, Dingmiao, combined with fixed seedlings per acre with ammonium sulfate 3 kg, with decomposing manure urine for raising seedlings. The manure fertilizer has a great effect on promoting the growth, growth and fruit growth of rape, and the bud fertilizer generally accounts for 30%-40% of the total fertilizer. The seed number and grain weight of rapeseed are related to the nutritional conditions in the later period. When flowering and scabbing, if air and light transmission are good and not shaded, 1% urea or superphosphate or potassium dihydrogen phosphate can be sprayed.
4. The demand for phosphorus in rapeseed is lower than that of potassium, but the reaction is sensitive. Phosphorus can promote growth and increase seed oil content. Phosphorus can be used repeatedly in the rapeseed, and it can be used as a fertilizer or transplanting. It should be applied before 5 leaves at the latest. The root system of rapeseed has strong ability to absorb phosphorus, and it is better to use calcium, magnesium and phosphate fertilizer for acid soil rapeseed. It is also effective to apply phosphate rock that is hardly soluble in water. Phosphate fertilizer consumption is generally 20-30 kg of superphosphate or calcium magnesium phosphate fertilizer per acre.
5. When the soil lacks potassium, and the available potassium content is less than 90 mg/kg, the effect of potassium fertilizer combined with N and P fertilizers is obvious, while the effect of K fertilizer alone is low. Potassium fertilizer is the best for centralized application of base fertilizer, with potassium chloride 5-10 kg per mu.
6, rape is sensitive to the trace element boron, boron deficiency will "flower but not real." Rapeseed Honda applied boron, sprayed once at seedling stage, flood season, and early flowering stage. Each time, 50 grams of borax was used per acre, and 50 kg of water was used to spray foliar. The effect was good. However, boron must not be used excessively to avoid poisoning.
