摘要
我国南方地区土壤常年受雨水淋溶,缺镁、缺硼现象严重。根据硼泥和硅钙钾镁肥的有效成分、农作物对硼和镁的需求,设计开发了硅钙钾镁硼肥,并开展了实验室小试、工业化生产和大田试验。结果表明:硅钙钾镁硼肥施用量为750 kg/hm^2时,可以满足缺硼、缺镁土壤条件下作物对有效硼和有效镁的需求;利用生产颗粒肥料的常规设备,可以满足对颗粒硅钙钾镁硼肥的生产要求。
The soil in southern China is leached by rain all the year round,there is a phenomenon of serious deficiency of magnesium and boron.Based on the effective composition of boron mud and silicon-calcium-potassium-magnesium fertilizer,and the demand of crops for boron and magnesium,silicon-calcium-magnesium-magnesium-boron fertilizer is designed and developed,and laboratory experiment,industrial production and field experiment are carried out.The results show that when the application amount of silicon-calcium-potassium-magnesium-boron fertilizer is 750 kg/hm^2,it can meet the demand of crops for available boron and available magnesium under the conditions of boron and magnesium deficiency soil;the conventional equipment used in the production of granular fertilizers can meet the production requirements of granular silicon-calcium-potassium-magnesium-boron fertilizer.
