| 摘 要： | 以夏红1号和长葫芦柿为试材,采用田间小区试验和田间调查试验,研究聚天门冬氨酸同源多肽对西红柿生物学性状和产量的影响。结果表明:聚天门冬氨酸同源多肽可增强西红柿生长势,使西红柿提早进入结果期,聚天门冬氨酸同源多肽对西红柿的增产作用达极显著水平,单位面积产量比对照增加9.33%;其销售量比对照增加37.52%,以销售收入核算的产出投入比达10.91,可显著提高西红柿的经济收益。田间试验调查发现:聚天门冬氨酸同源多肽对培育西红柿壮苗效果显著,对西红柿的大田长势及抗病方面也有显著的积极作用,并且病虫害的发生比对照明显减少。 |

| Abstract: | Effects of the homologous polypeptides of polyaspartic acids(PASP) on the tomato biology characters and its yield were studied by the field experiment and the field test survey.The results were showed the yield of the tested tomato increased significantly by 9.33% using PASP.The harvest-time for the sale of the tested tomato advanced and its commodity rate could increase in sales by 37.52%,with the ratio of output to input of 10.91 by the sale inputs.And so,the economic benefits of tomatoes improved significantly using PASP.The field test survey also showed PASP could make the tomato seedling stronger,and also promote the tomato growth and its disease-resistance with much less disease than the control. |
