摘要： 试验研究了土壤不同营养状况对强筋小麦子粒产量和品质的影响。结果表明:在10个处理中,土壤长期施用N,P,K等主要营养元素且配合比为1∶1∶1(N120.0kg/hm2,P2O5120.0kg/hm2,K2O120.0kg/hm2)时产量最高为5433.0kg/hm2,不施肥(ck)产量最低为1260.0kg/hm2;蛋白质含量以单施N素(N120.0kg/hm2)时最高达17.00%,N、P元素配合比为1∶1(N60.0kg/hm2,P2O560.0kg/hm2)时蛋白质含量最低为10.53%;蛋白质产量以N、P配合比为3∶1(N180.0kg/hm2,P2O560.0kg/hm2)时最高为696.0kg/hm2,以单施P素蛋白质产量最低为156.0kg/hm2。

Abstract: The effect of different nutrition conditions in soils on yield and qualities of high gluten wheats was presented in this paper. The results showed that among the 10 treatments studied, the highest grain yield come from the long-term application of N, P and K with a rate of 1B1B1( 120 kg/ ha for each), which is 5 433. 0 kg/ ha, and the lowest from control of no fertilizer application ( 1 260. 0 kg/ ha). For the protein content, the treatment of applying 120 kg of N whithout other fertilizer is the highest( 17%), and the combination of N and P at a rate of 60 kg/ ha for each the lowest. As to protein yield, the combination of 180 kg/ ha N and 60 kg/ ha P with a proportion of 3B1 results in the highest( 696. 0 kg/ ha), and the treatment of merely applying P the lowest( 156. 0 kg/ ha).
