摘要
覆膜花生以含N、P、Ca、S的化肥施入表土层0～10cm内,预供果针入土后直接吸收,较常规法施入0～20cm全耕层内的,增加了光合产物向荚果积累,4年平均,明显增产15.84％,荚果质量提高,肥效增加近2倍。
The results of experiments in peanut (Arachis hypogaea L.) under plastic-film-covered cultivation showed that applying fertilizer containing N、P、Ca and S to the fruiting-zone, top soil of 0～10cm in depth, for pegs to absorb increased the accamulation photosynthetic products in pods significantly increased the average pod yield of four years by 15.84% improved pod quality and nearly doubled the fertilizer efficiency in comparison with the popularized method of applying fertilizer to the full plough layer of 0 ～20cm in denth.
