摘要:

为考察聚天冬氨酸(PASP)对小麦群体指标、产量、产量构成因子、经济效益等的影响,以不添加PASP的处理为对照,开展了田间小区试验。结果表明:在普通复合肥中添加PASP,可以提高小麦的单株分蘖数、有效穗数和成穗率等群体指标;PASP添加量为施肥量的0.4%时效果较理想,小麦产量达到了8 509.5 kg/hm2,纯收益达到18 001.2元/hm2,产投比为7.4,较对照处理增产8.3%,纯收益增加1 538.6元/hm2,产投比提高0.5。在河南省安阳地区小麦生产上推广应用PASP时,建议其添加量为施肥量的0.4%。

Abstract:

In order to investigate the effects of polyaspartic acid (PASP) on population indexs, yield, yield components and economic benefits of wheat, a field plot experiment is conducted with the treatment without PASP as the control. The results show that adding PASP to regular compound fertilizer could improve the population indexes of wheat, such as tiller number per plant, effective panicle number and percentage of earing. The ideal effect is reached when the amount of PASP is 0.4% of the amount of fertilizer applied. The wheat yield reaches 8 509.5 kg/hm2, the net income reaches 18 001.2 yuan/hm2, and the ratio of production to investment is 7.4. Comparing with the control treatment, the yield increases by 8.3%, the net income increases by 1 538.6 yuan/hm2, and the ratio of production to investment increases by 0.5. When PASP is applied to wheat production in Anyang, Henan Province, the suggested addition amount of PASP should be 0.4% of the total fertilizer amount.
