两种野生绿肥对小白菜生长和营养品质的影响

Influence of application of two wild green manures on growth and nutritional quality of pakchoi

  • 摘要: 通过盆栽试验,研究了夏秋两季连续施用野生绿肥植物,即:罂粟科博落回属(Macleaya)(GMⅠ)和壳斗科栎属(Quercu)(GMⅡ),对小白菜生长及其营养品质的影响。结果表明,与夏季绿肥与尿素配施相比对照显著提高小白菜产量,秋季绿肥Ⅰ的所有处理比对照和单施尿素都能显著提高小白菜的产量;两种绿肥与尿素配施及绿肥Ⅰ单独施用能显著提高小白菜全年的产量。与单施尿素和绿肥加倍单施处理相比,夏季秋季绿肥单施和绿肥尿素配施能显著降低小白菜可食部分硝酸盐含量;秋季各绿肥处理都增加维生素C含量,但夏季差异不明显;夏季秋季各绿肥处理都增加可溶性糖含量,且秋季增加更显著。两种野生绿肥在夏秋季连续施用条件下,秋季能比尿素更有效的提高小白菜产量和营养品质,尤以绿肥Ⅰ的效果最好。

     

    Abstract: Influence of continuous application of two wild green manures of Macleaya(GMⅠ)and Quercu(GMⅡ) with high nitrogen content both in summer and autumn on growth and nutritional quality of pakchoi(Brassica chinensis L.)was studied using pot experiments. Compared with CK, shoot fresh weights are significantly increased with the application of mixture of the green manures with urea in summer, while compared with both CK and urea treatments, shoot fresh weights are significantly increased with the application of the GM I treatments in autumn. Yields of pakchoi in whole year are notably increased when mixture of the green manures with urea, and GMⅠused alone. Compared with urea and double green manure treatments, the nitrate contents of the eatable part of pakchoi are remarkably decreased for the green manures used alone and mixture of the green manures with urea treatments in the two seasons. All treatments with two green manures could increase vitamin C content in autumn. Soluble sugar contents are improved by the two green manures both in summer and autumn, and benefits are even better in autumn. In conclusion, compared with urea used alone, the two green manures could increase yield and enhance nutritional quality of pakchoi in autumn, and the GMⅠis found to be the best.
