| Popis: |
In this experiment, the asbestos chinensis was selected as the experimental material, and it was treated with black mulch, straw mulch, horticultural cloth mulch and river sand mulch, and compared with the control group to study the correction of iron deficiency yellowing of the leaves of Huangguogan. The results showed that the application of chelated iron under different mulching materials can significantly improve the photosynthesis index and leaf fluorescence characteristics of leaves, and correct the problem of iron deficiency yellowing of yellow fruit orange. The degree of correction of leaf iron deficiency yellowing by root-chelating iron was different under different mulching materials. In general, the correction effect of river sand mulch treatment was the most obvious, and the correction effect of black mulch was the worst. It was economical, practical, simple and convenient to correct the iron deficiency yellowing of the yellow fruit by mulching the material, and it had certain promotion value. |
