Problems solved by technology

[0002] Due to continuous cropping obstacles in the cultivation of Rehmannia glutinosa, repeated cropping is usually not possible. The method to overcome continuous cropping obstacles is usually to carry out crop rotation at intervals of 3 or more years, which greatly limits the cultivation of rehmannia glutinosa in genuine medicinal material producing areas
[0003] In addition, in order to overcome continuous cropping obstacles, many people try to achieve their goals by spraying anti-cropping agent pesticides or fumigation soil into the soil, but the results are not great and the environment is polluted.

Embodiment 1

[0025] A method for planting Rehmannia glutinosa overcoming continuous cropping obstacles, comprising the following steps: (1) on a 5-acre ground of rehmannia glutinosa, planting rhizomes of Rehmannia glutinosa that have reached the harvest period in the first year in the original hole as planting in the second year;

[0026] (2) Do not loosen the soil, water, or fertilize the soil within the circle with the original hole as the center and a radius of 10 cm, and try to keep the soil in this area from being damaged;

[0027] (3) Picking is carried out when it is to be harvested, and the harvested amount is 35,000 kilograms. The average annual yield per mu is 3500 kg, and the pharmacopoeia indicators such as catalpol, verbascoside and rehmannia polysaccharide content in Rehmannia glutinosa reached 3.5%, 0.12% and 6.9% respectively.

Embodiment 2

[0033] A method for planting Rehmannia glutinosa overcoming continuous cropping obstacles, comprising the following steps: (1) on a 5-acre ground of rehmannia glutinosa, planting rhizomes of Rehmannia glutinosa that have reached the harvest period in the first year in the original hole as planting in the second year;

[0034] (2) In the soil area within the radius of 10cm with the rhizome as the center, do not loosen the soil, water, or fertilize, and try to keep the soil state in this area from being damaged;

[0035] (3) When harvesting is still not carried out, the rhizomes of Rehmannia glutinosa that have reached the harvest period in the second year are planted in the original hole as the planting of the third year;

[0036] (4) In the soil area within the radius of 10cm and the rhizome as the center, do not loosen the soil, water, or fertilize, and try to keep the soil state in this area from being damaged;

[0037] (5) Picking is carried out when waiting to be harvested...

Embodiment 3

[0039] A method for planting Rehmannia glutinosa overcoming continuous cropping obstacles, comprising the following steps: (1) on a 5-acre ground of rehmannia glutinosa, planting rhizomes of Rehmannia glutinosa that have reached the harvest period in the first year in the original hole as planting in the second year;

[0040] (2) In the soil area within a circle with a radius of 10cm centered on the rhizome, do not loosen the soil, water, or fertilize, and try to keep the soil state in this area from being damaged.

[0041] (3) When fertilizing the rhizomes used for planting in the second year, the horizontal distance between the fertilization position and the planting should be at least 10cm. Fertilization time is early April, and the amount of fertilizer is applied to each hole containing 0.3% KH 2 PO 4 and 0.5% KNO 3 Composite aqueous solution 0.5Kg.

[0042] (4) When the harvest is to be harvested, the harvest is 38,000 kg. The average annual yield per mu is 3,800 kg, ...

Abstract

The invention provides a rehmannia glutinosa planting method for overcoming continuous cropping obstacles. The drug properties and quality of rehmannia glutinosa are improved. The rehmannia glutinosaplanting method for overcoming the continuous cropping obstacles comprises the following steps that rhizomes of last-year rehmannia glutinosa which enters the harvest period stay in planting in primary holes and used for next-year planting. According to the rehmannia glutinosa planting method, continuous cropping of rehmannia glutinosa can be achieved for three or more years, the annual average yield is greatly increased, the annual average yield per mu is at least 3,500 kilograms, and the planting cost and planting difficulty are lowered. By means of the method, the quality and drug properties of rehmannia glutinosa planted through continuous cropping are improved, and the content of catalpol, verbascoside and rehmannia polysaccharide reaches above 3.5%, above 0.12% and 6.9% respectively.

Description

technical field [0001] The invention relates to a method for planting rehmannia glutinosa, in particular to a method for planting rehmannia rehmannia overcoming continuous cropping obstacles. Background technique [0002] Rehmannia glutinosa can not be replanted due to continuous cropping obstacles. The method to overcome the continuous cropping obstacles is to carry out crop rotation at intervals of 3 or more years, which greatly limits the planting of rehmannia glutinosa in genuine medicinal material producing areas. [0003] In addition, in order to overcome continuous cropping obstacles, many people try to achieve their goals by spraying anti-cropping agent pesticides or fumigation soil into the soil, but the results are not great and the environment is polluted. Contents of the invention [0004] In order to solve the above problems, the present invention provides a method for planting rehmannia glutinosa that overcomes continuous cropping obstacles and improves the p...
