高沙土农业区基本由纯旱制过渡到稻麦两熟水旱轮作制。由于受成土母质影响,高沙土土壤中的硅以钙结合态为主,硅酸钙盐不易水解,难以生成单硅酸供植物吸收。为此,我们进行了小麦应用硅肥的探索和研究,为大面积生产提供科学依据。1材料和方法 试验设在姜堰大泗霍堡村纪如贵责任田。参试土壤沙土。土壤有机质1.17％,速效磷5.9mg/kg,速效钾67mg/kg,有效硅56mg/kg。处理设:(1)对
Gao Sha soil farming area basically by the pure drought system to rice and wheat two-wheeled crop rotation system. Due to the influence of soil parent material, the silicon in high sand soil is mainly calcium-bound, calcium silicate is not easily hydrolyzed, and it is difficult to generate monosilicic acid for plant absorption. To this end, we conducted a wheat application of silicon fertilizer exploration and research for large-scale production to provide a scientific basis. A material and method test is located in Jiangyin Great Sihe Fort village Ji Rui responsibility field. Soil test soil. Soil organic matter 1.17%, available phosphorus 5.9mg / kg, available potassium 67mg / kg, effective silicon 56mg / kg. Processing set: (1) right
