摘要
以鲁麦22为试材,研究微晶化磷矿粉对小麦生长、吸磷量及产量的影响。结果表明:微晶化磷矿粉能显著提高小麦分蘖数,促进植株生长,增加叶片SPAD值和干物质含量;也可以促进小麦秸秆和籽粒磷素的积累;还可以提高小麦产量。微晶化磷矿粉较过磷酸钙节约成本202.5元/hm2,纯收入增加0.69%,有利于农民增收。由此认为,微晶化磷矿粉是一种增产、经济的新型磷肥。
The field experiment was conducted to study the effect of microerystalline phosphate rock powder on growth, P content and yield with Lu22 wheat.The results showed that the microcrystalline phosphate rock powder could improve tiller number, proraote plant growth and increase leaf SPAD value and dry matter content;and also could increase P content of straw and grain.Additionally,it could increase yield of wheat.In contrast to the calcium superphosphate treatment,the cost of microcrystalline phosphate rock superphosphate could save about 202.5 yuan per hectare and the net income increased by 0.69% in favor of farmers＇ income.It was proposed that microcrystalline phosphate rock was a new type of phosphorus fertilizer which was economic and could increase yield.
