摘要
通过不同配方复混肥的比较试验,为水稻肥料的合理施用提供依据。结果施用NPK化肥和各配方复混肥料对水稻生长发育有良好的促进作用,株高、有效穗、穗长和单穗重明显增加,穗粒数显著增多。水稻籽粒产量较不施肥的空白对照增长38.1%-53.7%,平均增产43.7%。施肥增收1450-4012元/hm2,产投比为1.73-3.06∶1。三种复混肥料中,测土配方专用肥效果最好,增产节本增收效应明显。
This study aimed to compare different prescription compound fertilizer on rice yield and fertilization profit so as to provide the basis for rice rational fertilization. Result the effect of NPK and different prescription fertilizer on rice growth was obvious, plant height, the seeded spike, length and weight of spike increased obviously. Rice seed yield increased by 38. 1% - 53.7% averagely 43.7%. Profit of fertilization improved by 1450 -4012Yuan/hm^2 , the value cost ratio reached 1.73 -3.06： 1. The prescription fertilizer had an effect of yield promotion, cost save and profit increases among three compound fertilizer.
