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、3.5kg/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2.0kg/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。
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.
