用江汉平原灰潮土进行小麦、油菜、蚕豆和棉花锰肥盆栽和田间试验。结果表明：①这４ 种作物施用锰肥增产效果显著。②不同用量的硫酸锰作基肥施在小麦、油菜和蚕豆上，其肥料效应函数相似，不同的是蚕豆需要的锰肥用量略高。③用０ ．１％ 的硫酸锰溶液浸种或移栽时浸根加生殖生长期喷施增产效果好。④用硫酸锰拌种，对棉花的增产效果比作基肥的好，两者差异极显著；对小麦和蚕豆的增产效果略优于作基肥的增产效果；对油菜则相反，作基肥比拌种产量高且差异达到极显著水平。
Phytolith fertilization and field experiments of wheat, rape, broad bean and cotton with Jianghan plain gray soil. The results showed that: (1) The yield increase of these four kinds of crops with Mn fertilizer was significant. ② Different amounts of manganese sulfate applied as basal fertilizer on wheat, rape and broad bean, the fertilizer effect function is similar, the difference is that the amount of manganese fertilizer required for broad beans is slightly higher. ③ with 0. 1% manganese sulfate solution soaking or transplanting soaking roots and reproductive growth spraying good yield. ④ with manganese sulfate seed dressing, the cotton yield is better than the base fertilizer, the difference between the two is very significant; wheat and broad beans yield slightly better than the base yield; the opposite of the rapeseed than the seed dressing High yield and the difference reached a significant level.
