Effects of Rare Earths in Agriculture on Photosynthetic Characteristics of Canopy and Quality of Waxy Corn
With different concentration of rare earths in agriculture (T1 ,T2 ,T3 ,T4,T5 ,CK) , the effects of rare earths on average foliage tilt in the group, PAR, light transmission, CAP, the characteristics of morphology and qulity of Waxy Corn 2062 were investigated. The results were as follows: when concentration of rare earths was 400 mg · kg-1, the LAI of different posi-tion was the biggst at the different growth stages after pollination; the average foliage tilt in the group of waxy corn was the smallest and showed significant differences compared with other trestmentjin 18 days after pollination, PAR reached the high-est value; light transmittance through canopies of waxy corn community increased firstly and then decreased with growth after pollination. The difference of CAP was not obvious. The arrangement of fresh - eating waxy corn cooking quality from large to small by total score: T1 = T3 > CK > T2 = T4 > T5.
