摘要
通过增施有机肥和氮磷化肥,研究不同组合形式及施用方式对薄地小麦产量和生长发育的影响,结果表明,氮磷配合增施化肥能够显著促进分蘖的出现与生长。小麦产量750 kg/hm2左右的低产薄地,施优质圈肥7.5万kg/hm2、尿素375～450 kg/hm2、标准过磷酸钙750～1 125 kg/hm2,当季产量可达6 000～6 750 kg/hm2,甚至更高。
The effects of combinations and application method on output and growth of wheat in infertile land were studied by applying organic fertilizer and nitrogen phosphorus fertilizer. The results showed that the increasing of the nitrogen phosphorus coordination fertilizes could obviously promote the appearance and the growth of the branch tiller. The infertile land with yield of 750 kg/ hm^2 employed high quality barnyard manure 7 5000 kg/hm^2, urea 375-450 kg/hm^2, standard per phosphoric acid 750-1 125 kg/ hm^2, the production may reach 6 000-6 750 kg/hm^2, even higher.
