Problems solved by technology

At present, the under-forest planting of Polygonatum adopts loose pond planting and sub-compartment planting under the forest. Because of the well-developed root system of the forest and strong fertilizer absorption capacity, most of the fertilizer fertilized to Polygonatum is absorbed by the roots of the trees, resulting in the fertilizer utilization rate of Polygonatum. If it is too low, it will affect the growth of Polygonatum, resulting in low growth and low quality of Polygonatum, easy to expose the soil, turn green, small individuals, and easily deformed

Embodiment 1

[0027] The ridge-root separation cultivation method of Polygonatum Polygonatum under the forest, through the following steps:

[0028] (1) Clearing the forest and pruning: In mid-October, weeds in the forest (sparse forest) and small trees with a trunk diameter of less than 8 cm should be removed, and branches with luxuriant branches and poor ventilation and light transmission should be cut off, so that the light transmittance of the forest can reach 50 % or more, and collect the weeds and branches that have been cleared for centralized retting to make organic fertilizer;

[0029] (2) Deep plowing and drying: After clearing the forest, carry out deep plowing on the soil, requiring a depth of more than 30cm, and drying for more than 30 days;

[0030] (3) Fine crushing and leveling, base fertilizer application: after drying, crush the soil and make fine crushing and leveling (levelling along the contour line on gentle slopes), according to the rate of every m 2 Apply 3kg of org...

Embodiment 2

[0044] The ridge-root separation cultivation method of Polygonatum Polygonatum under the forest, through the following steps:

[0045] (1) Clearing the forest and pruning: In mid-October, weeds in the forest (sparse forest) and small trees with a trunk diameter of less than 8 cm should be removed, and branches with luxuriant branches and poor ventilation and light transmission should be cut off, so that the light transmittance of the forest can reach 50 % or more, and collect the weeds and branches that have been cleared for centralized retting to make organic fertilizer;

[0046] (2) Deep plowing and drying: After clearing the forest, carry out deep plowing on the soil, requiring a depth of more than 30cm, and drying for more than 30 days;

[0047] (3) Fine crushing and leveling, base fertilizer application: after drying, crush the soil and make fine crushing and leveling (levelling along the contour line on gentle slopes), according to the rate of every m 2 Apply 3.5kg of o...

Embodiment 3

[0061] The ridge-root separation cultivation method of Polygonatum Polygonatum under the forest, through the following steps:

[0062] (1) Clearing the forest and pruning: In mid-October, weeds in the forest (sparse forest) and small trees with a trunk diameter of less than 8 cm should be removed, and branches with luxuriant branches and poor ventilation and light transmission should be cut off, so that the light transmittance of the forest can reach 50 % or more, and collect the weeds and branches that have been cleared for centralized retting to make organic fertilizer;

[0063] (2) Deep plowing and drying: After clearing the forest, carry out deep plowing on the soil, requiring a depth of more than 30cm, and drying for more than 30 days;

[0064] (3) Fine crushing and leveling, base fertilizer application: after drying, crush the soil and make fine crushing and leveling (levelling along the contour line on gentle slopes), according to the rate of every m 2 Apply 4kg of org...

Abstract

The invention discloses an undergrowth polygonatum sibiricum ridge root separation and cultivation method. The method comprises the steps of forest clearing and pruning, deep ploughing and upterned soil sunning, fine flat finishing, base fertilizer applying, road planning, ridge root separating, sowing and managing, polygonatum sibiricum growth is accelerated, annual growth is increased by 20%, the amount of application of fertilizer is reduced, the fertilizer applied per mu can be decreased by about 400-500 kg compared with polygonatum sibiricum planted under an ordinary forest, the fertilizer utilization rate is increased by 20-30% compared with cultivation under the ordinary forest, the harvested polygonatum sibiricum is large in rhizome individual, white in epidermis and regular in shape, no malformation exists, and the yield is increased. According to the method, the problems that at present, in the undergrowth polygonatum sibiricum planting process, the fertilizer utilization rate is too low, the growth is low, and the quality is low are effectively solved.

Description

technical field [0001] The invention relates to a ridge-root separation cultivation method of Polygonatum Polygonatum, belonging to the technical field of plant cultivation. Background technique [0002] At present, Polygonatum is mainly cultivated in three ways: shade net shed cultivation, orchard intercropping, and understory planting. [0003] The sun-shade net shed cultivation of Huang Jing needs to be built, and the sun-shade net shed needs to be replaced every two to three years, which is labor-intensive and time-consuming, resulting in increased costs and affecting profitability. On the other hand, due to the large number of planting industries, the competition for land and seasons between crops is increasing. Prominent, and the sealwort planting cycle is long, the bases that can be used for the plantation of sealwort are less and less, resulting in a serious shortage of arable land for planting sealwort, restricting the development of sealwort industry. [0004] On ...
