ClayF缓释复肥对小麦生长发育的影响

ClayF缓释复肥是一种包含丰富中、微量元素的缓释粘土矿物包膜肥料,具有多种生物活性.盆栽试验结果表明:红壤旱土施用适量的ClayF缓释复肥可有效提高小麦的根重、株高、有效分蘖、穗长、实粒数、千粒重和地上部分干重,籽粒产量比对照增加12%.适量的ClayF缓释复肥同时能增强小麦对氮、磷、钾养分的吸收,促进氮、磷、钾养分向小麦籽粒转运.

Effects of Clay-coated slow-released compound fertilizer on growth and development of wheat

A slow-released compound fertilizer,ClayF,has abundant secondary nutrients and microelements,and possesses a wide range of bioactivity.Effects of different ClayF application rates on growth and development of wheat were studied in the pot experiments.The results showed that root weight,plant height, productive tillers,ear length,full spikelets,1 000-grain weight and dry weight of aerial part of wheat increased when proper amount of ClayF was applied into arid red soil,and the grain yields of wheat increased by 12% as compared to the control.Suitable application of ClayF also increased absorption and promoted transport of nitrogen,phosphorus and potassium to the grains of wheat.
