Benefits of technology

This patented inventor describes an improved way of growing polygalactomannan plants called Cuscuta oligocarpicata (Cox) which involves combining cuts from different parts together like roots or stems. By doing this they make better yields while also improving their ability to fight off diseases such as fungi attacks on crops caused by these bacteria.

Problems solved by technology

Technological Problem addressed in this patented text describes how Phytopharmacology (PCA), an organic chemical called Rhodiol® that helps stop bleeding caused by wounds during physical therapy treatments such as surgery, debility management, etc., while also being able to promote healing processes like cellular necrosis and inflammations through activation of defense mechanisms including immune responses against bacteria and viruses. Additionally, People's Grander Cake Collection provides technical solutions related to growing Prussian blue green crops containing polyhedronium cuscodes Bactrum Spragulosa Linnema variegata).

Embodiment 1

[0023] Propagation of knotweed seedlings:

[0024] a. The layering time is selected from May to June every year. The environment for breeding and raising seedlings requires ventilation, convenient drainage and irrigation, the shading rate is 70-80%, and the relative humidity is controlled at 75-85%;

[0025] b. Use branch scissors to cut the top stem nodes of semi-lignified Polygonum cuspidatum plants with terminal buds that are born in the same year, grow vigorously and have no pests and diseases, and make cuttings. 3 new leaves, all the leaves at the bottom are cut off, and the remaining leaves are kept intact without cutting. Dip the cuttings into the mud containing rooting agent. The mud containing rooting agent is made of yellow mud and 100-150mg / L ABT3 aqueous solution It is mixed according to the mass ratio of 1:2, inserted into the river sand matrix for 3 to 4 cm, and the part with leaf scars is completely buried in the sand, watered immediately after the cuttings, and...

[0030] Propagation of knotweed seedlings:

[0031] a. The layering time is selected from May to June each year. The environment for breeding and raising seedlings requires ventilation, convenient drainage and irrigation, the shading rate is 70-80%, and the relative humidity is controlled at 75-85%;

[0032] b. Use branch scissors to cut the top stem nodes of semi-lignified Polygonum cuspidatum plants with terminal buds that are born in the same year, grow vigorously and have no pests and diseases, and make cuttings. 3 new leaves, all the leaves at the bottom are cut off, and the remaining leaves are kept intact without cutting. Dip the cuttings into the mud containing rooting agent. The mud containing rooting agent is made of yellow mud and 100-100mg / L ABT6 aqueous solution It is mixed according to the mass ratio of 1:3, inserted into the river sand matrix for 3 to 4 cm, and the part with leaf scars is completely buried in the sand, and watered immediately after the cuttings. ...

Dip the cuttings into the mud containing rooting agent. The mud containing rooting agent is made of yellow mud and 100-120mg / L ABT3 aqueous solution It is mixed according to the mass ratio of 1:1, inserted into the river sand matrix for 3 to 4 cm, and the part with leaf scars is completely buried in the sand, and watered immediately after cuttings.

Abstract

The invention relates to the technical field plant reproducing, in particular to a method for rapidly and efficiently reproducing a polygonum cuspidatum seedling. The method includes the steps that a, May to June every year is selected as moulding time, ventilation and convenient irrigation and drainage are achieved in a reproduction seedling culture environment, the shading coefficient ranges from 70% to 80%, and the relative humidity is controlled to range from 75% to 85%; b, a top end stem node with a terminal bud is flat sheared to serve as a cutting, the cutting is dipped in mud containing a rooting agent, the cutting is inserted into a river sand matrix, and a cutting seedling with the terminal bud is obtained; c, leaves of a remaining polygonum cuspidatum plant obtained after the top end stem node with the top bud is sheared off are pruned with pruning shears, 3-5 leaves close to the top are reserved, a top end notch is sterilized and disinfected, bulldozing is carried out, and a moulded plant is obtained; d, the cutting seedling with the terminal bud and an adventitious root at the leaf scar position of the moulded plant are generated, at the moment, the cutting seedling with the terminal bud can serve as a seedling to be transplanted, and the polygonum cuspidatum seedling is obtained. According to the method for reproducing the polygonum cuspidatum seedling, cutting and mound layering methods are combined, the cutting survival rate of the top end stem node reaches 97%, the rooting rate of leaf-free stem nodes reaches 93%, and the survival rate of rooting stem nodes reaches 100%.
