- 摘要:
- 以连作4年草莓的土壤为研究对象，以蚯蚓粪改良剂为试材，研究了0、1.5、2.0、2.5、3.0、3.5 kg/m2不同改良剂用量对草莓生长、品质和产量的影响，以期为更好地克服草莓连作障碍提供参考。结果表明：改良剂用量为2.0 kg/m2时对土壤的综合改良效果最好，草莓株高和分枝的增长量最高，与对照相比，分别增加了4.6%和8.6%；草莓产量提高了21%左右；糖分含量提高了17.4%；维生素C含量提高了11.7%。说明改良剂在克服草莓连作障碍，改善草莓品质方面具有良好的效果。
- Abstract:
- Taking the soils that planted 4-year-old strawberry as research object,with earth-cast modifier as material,the effect of different modifier dosage(2.0,2.5,1.5,3.0,3.5 kg/m2) on yield,growth and quality of strawberry were studied,in order to overcome the continuous cropping obstacle.The results showed that the modifier dosage of 2.0 kg/m2 comprehensive improvement worked the best,the plant height and branching of strawberry were the highest amount of growth,respectively,compared with the CK increased by 4.6% and 8.6%,yield of strawberry increased about 21%,sugar content increased by approximately 17.4%,and Vitamin C content increased by 11.7%.The modifier achieved good results in overcoming the continuous cropping obstacle and strawberry quality improvement.
