不同营养液配方对麦苗产量及生长的影响

Effects of different nutrient solution on yield and growth of wheat seedlings

摘要: 研究4组不同营养液配方对麦苗产量及生长的影响，结果表明：不同营养液配方的麦苗产量及生长有显著差异，其中配方为360 mg/L Ca（NO₃）₂·4H₂O+775 mg/L KNO₃+250 mg/L NH₄H₂PO₄+200 mg/L MgSO4·7H₂O处理的麦苗产量最高，第2次割苗比第1次割苗在产量、苗数、生长速率等均有不同程度的降低。

Abstract: Effects of 4 different nutrient solution formula on the yield and growth of wheat seedling were studied. The results showed that obvious differences were observed in the yield and growth of wheat seedlings by using different nutrient solutions formula, among that, the using of formula of 360 mg/L Ca(NO₃)₂·4H₂O+ 775 mg/L KNO₃+ 250 mg/L NH₄H₂PO₄+ 200 mg/L MgSO₄·7H₂O, the yield were the highest and compared with the 1st cutting, the yield, seedling number and growth rate in 2nd cutting were decreased to some distance.
