Waterlogging-preventing method for Polygonatum sibiricum Red. planting

Abstract

The invention relates to a waterlogging-preventing method for Polygonatum sibiricum Red. planting. The method is characterized in that Polygonatum sibiricum Red. seedlings are planted according to rows, a gap exists between every two rows, plant fiber nonwoven fabric is laid on each gap, and the water permeability q of each plant fiber nonwoven fabric is 5-20Lu; a groove is formed in each gap, andthe depth of the groove is not larger than that of Polygonatum sibiricum Red. planting pits. The method has the advantages that a good waterlogging-preventing effect is achieved, nutrition in soil can be well protected from losing easily, and moisture can be effectively retained in drought to guarantee that the Polygonatum sibiricum Red. is constantly located in a good-moisture growth environment.

Description

technical field [0001] The invention relates to a method for preventing waterlogging, in particular to a method for preventing waterlogging of Polygonatum planting. Background technique [0002] Rhizoma Polygonatum is a precious Chinese herbal medicine.

Problems solved by technology

[0003] The climate and soil conditions in southern my country are very suitable for the growth of Polygonatum, but the southern area is generally cloudy and rainy, and the roots of Polygonatum are easily soaked in water and rot, which leads to the death of Polygonatum plants. Therefore, the planting process of Polygonatum Great attention should be paid to waterlogging prevention in the planting. The existing waterlogging prevention method in the planting of Polygonatum is generally by digging drainage ditches or planting Polygonatum on the slope, and utilizing the drainage ditch or slope to carry out rapid drainage. Although this kind of method will achieve better Drainage and waterlogging prevention effect, but this method will cause a large loss of nutrients in the land where Polygonatum is planted, which not only causes a waste of resources, but also affects the growth of Polygonatum, and this method is also prone to lack of water in Polygonatum due to excessive drainage. Water is also not conducive to the normal growth of Polygonatum
