Embodiment 2
[0067] Embodiment 2 The test effect of compound trace element liquid foliar fertilizer of the present invention on litchi
[0068] In Xili fruit farm in Shenzhen, the compound trace element liquid foliar fertilizer of the present invention was diluted 1000 times to spray glutinous rice cakes with a tree age of about 13 years, which was used in the fruit development period, and good results were obtained. As can be seen from Table 1 and Table 2, the yield increased by 13.8% compared with the control, and the sugar content increased by 6.9% compared with the control.
