Problems solved by technology

The operation of winter bud propagation is relatively simple, but the number of winter buds in natural lakes is less and less, which cannot meet the large demand; the operation of tissue culture is cumbersome, the environmental requirements are relatively strict, and it is only suitable for shallow water bodies
However, the technology of using cuttings to propagate in nature is still immature, the rooting rate is low, and the survival rate is low, so it cannot be popularized.
Castoria is a pioneer species for repairing the damaged aquatic ecological environment, but there is no report on the direct cutting propagation technology of Riseria

Abstract

The invention discloses a potamogeton pectinatus direct cutting propagation method. The potamogeton pectinatus direct cutting propagation method comprises the following steps: selecting potamogeton pectinatus which has bright green color and grows strongly; cutting off 35-40 cm from the top of a leaf downwards; flushing the 35-40 cm parts by using clean water; selecting a mixture of lake bottom sediment and loess as culture soil; inserting a stem of an obtained explant into the culture soil; putting the culture soil into a water pond filled with natural lake water; guaranteeing that water in the water pond is over a container, the depth of the water in the water pond is 0.4-0.5 m, the length of the stem of the explant inserted into the culture soil is 15-20 cm, the depth of a branch of theexplant inserted into the culture soil is 4-6 cm, the row spacing is 8-10 cm, and the planting density is 10-20 plant / m2; after the explant is cultured for 5-8 days, adding water to the water pond toa water depth of 0.8-1.2 m; and after continuing to culture the explant for 5-8 days, transplanting the explant as a seedling. The potamogeton pectinatus direct cutting propagation method disclosed by the invention has the advantages that the operation is simple, the cost is low, the rooting percentage is 99% or above, and the transplanting survival rate is 99%.

Description

technical field [0001] The invention belongs to the technical field of planting submerged plants, and in particular relates to a method for direct cutting and rapid propagation of submerged spinach. Background technique [0002] Potamogeton pectinatus, (scientific name: Potamogeton pectinatus L) is a perennial submerged plant of the family Potamogeton pectinatus. It is a submerged plant distributed all over the world. It grows in various water bodies such as river ditches, canals, ponds, lakes, etc. It has an outstanding purification effect on nitrogen and phosphorus in water bodies. C. ricinus has strong adaptability and wide distribution, and is a commonly used plant species for aquatic vegetation restoration and water pollution control. The root system of ricinia is well developed and the plants are longer, which can effectively inhibit the release of endogenous pollution and improve water quality. The water quality of natural waters in our country is seriously polluted...
