Fertilization method in polygonatum sibiricum growth process

Abstract

The invention discloses a fertilization method in a polygonatum sibiricum growth process. The method comprises the steps that 1, after polygonatum kingianum seedlings emerge, radial grooves are formed in the roots of polygonatum kingianum in the planting arrangement direction, and potash fertilizer, nitrogenous fertilizer and phosphatic fertilizer are applied correspondingly; 2, in the polygonatum sibiricum leaf division period, cake fertilizer obtained after proportioning fermentation is diluted, then the diluted cake fertilizer is applied to the position 20 cm to 30 cm away from the roots of polygonatum sibiricum plants according to the growth vigor of the polygonatum sibiricum plants, and earthing and soil moisture conservation are conducted; 3, farmyard manure is added into the ditches in April, May and June, and 100-150 kg of air-dried human and animal manure is selected and applied dispersedly per mu each time; 4, bacterial fertilizer is added into sandy loam, a small amount of nitrogenous fertilizer is supplemented, the mixture is mixed and stirred to be uniform, the mixture is applied to the roots of polygonatum sibiricum plants in the middle ten days of September, and earthing and sun shading are conducted; and 5, chicken manure is added into plant rhizomes and fruit shells for stack retting fermentation and applied in winter. The fertilization method in the polygonatum sibiricum growth process guarantees the yield of polygonatum sibiricum, meanwhile, the use amount of fertilizer is reduced, and the economic benefits of polygonatum sibiricum are increased.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilization, in particular to a fertilization method in the growth process of Polygonatum. Background technique [0002] Polygonatum, also known as: Chicken Head Polygonatum, Yellow Chicken Vegetable, Pen Tube Vegetable, Claw Ginseng, Tiger Ginger, Chicken Claw Ginseng. It is a plant of the genus Polygonatum, the rhizome is horizontal, cylindrical, and the nodules are enlarged. Leaves whorl, sessile. Medicinal plants have the functions of invigorating the spleen, moistening the lungs and promoting body fluid. The inflorescence usually has 2-4 flowers, which seem to be umbel-shaped, the total pedicel is 1-2 cm long, and the pedicel is (2.5-)4-10 mm long, drooping; bracts are located at the base of the pedicel, membranous, subulate or strip-shaped lanceolate, 3-5 mm long, with 1 vein; perianth milky white to pale yellow, 9-12 mm long, slightly constricted in the middle of the perianth tube...

Problems solved by technology

The inflorescence usually has 2-4 flowers, which seem to be umbel-shaped, the total pedicel is 1-2 cm long, and the pedicel is (2.5-)4-10 mm long, drooping; bracts are located at the base of the pedicel, membranous, subulate or strip-shaped lanceolate, 3-5 mm long, with 1 vein; perianth milky white to pale yellow, 9-12 mm long, slightly constricted in the middle of the perianth tube, lobes about 4 mm long; filaments 0.5-1 mm long, anthers The length is 2-3 mm; the ovary is about 3 mm long, and the style is 5-7 mm long. In order to increase the yield of Polygonatum, in the growth process of Polygonatum, it is necessary to add fertilizers at different stages to ensure sufficient nutrients. However, the existing The method of fertilization makes Polygonatum less efficient in absorbing fertilizers, and the amount of fertilizer is large, resulting in loss and waste of fertilizers, and the inconvenience of fertilization can not improve soil fertility, resulting in low economic benefits of Polygonatum, for this reason, we propose A fertilization method in the growth process of Rhizoma Polygonatum solves the above problems
