This study examines the relationship between family socioeconomic status, parent-child activities, and young children’s digital development. Using the Family SES questionnaire, the parent-child activities questionnaire, and the 5 to 6 year old children’s number sense development scale as research instruments, 314 young children (M = 70.42, SD = 3.47). The results show that: (1) Family Socioeconomic Status can significantly positively predict the young children’s number sense development; (2) Parent-child activities play a partial mediating role in the relationship between family socioeconomic status and the young children’s number sense development. This study provides specific guidelines and recommendations for improving the young children’s number sense development.</div

Above ground biomass with respect to N accumulation.

The relation between above ground biomass yield and N accumulation in the year (A) 2016, (B) 2017 and (C) both year pooled data.</p

Above ground biomass yield with respect to nitrogen concentration and accumulation under different treatment across the year.

(A, B) Changes in above ground biomass yield partitioning in grain and straw during 2016 & 2017, (C, D) changes in partitioning nitrogen concentration in grain and straw during 2016 & 2017, (E, F) changes in partitioning nitrogen accumulation in grain, and straw during 2016 & 2017. Bars indicate standard errors (n = 4). Treatments with different letters for the same variable analyzed (straw or grain) are significantly different according to the LSD test (P <0.05). T1 = Control, T2 = 100% CN, T3 = 100% CN + MBF, T4 = 75% CN + 25% ON + MBF, T5 = 50% CN + 50% ON+ MBF, T6 = 100% ON + MBF and T7 = 100% ON.</p
