Description

Method for promoting rooting of cynodon dactylon

Technical Field

The invention belongs to the technical field of garden plant cultivation, and particularly relates to a method for promoting radication of bermudagrass.

Background

The bermudagrass belongs to the grass family (Gramineae) and the genus bermudagrass, is one of warm-season turfgrass which has the highest value and is most widely applied to turfgrass, and is commonly used as turfgrass, pasture grass, urban greening or ecological grass for water and soil conservation. The bermuda grass has the excellent characteristics of drought resistance, flooding resistance, heavy metal resistance, trampling resistance, easy management and the like, and is an ideal grass seed for lawn propagation and heavy metal polluted land treatment.

The lawn propagation method mainly comprises seed propagation and vegetative (asexual) propagation, wherein the seed propagation cost is low, but the propagation speed is slow; in contrast, vegetative propagation is fast in lawn formation but at a higher cost. The roots of the warm-season turfgrass dogs can be propagated by using seeds, and the root system growth speed is slow, so that the lawn forming speed is slow. In the existing rooting technology, the rooting agent is mainly sprayed on leaf surfaces and soaked in seeds, the common rooting agents at present comprise naphthylacetic acid, indolebutyric acid, gibberellin, yugen, br rooting agents and the like, and most of the rooting agents of single varieties have very limited effects.

Disclosure of Invention

In order to solve the problems, the invention provides a technology for treating the bermuda grass seeds, the method for treating the bermuda grass seeds can obviously improve the rooting speed and the rooting amount of the bermuda grass, has the characteristics of simple working procedures, easy operation, low cost and short treatment period, and is convenient for batch treatment.

The technical scheme of the invention is as follows: a method for promoting the rooting of cynodon dactylon comprises the following steps:

(1) The seeds of Cynodon dactylon are poured into the mixture with the concentration of

Soaking seeds in the indolebutyric acid solution, stirring frequently in the seed soaking process to keep the upper and lower concentrations of the indolebutyric acid solution consistent, fully contacting the seeds with the indolebutyric acid solution, and filtering the seeds after soaking the seeds for 4-6 hours;

(2) Pouring the filtered seeds into a container, washing the seeds for 10 to 20 minutes by running water and then fishing out the seeds;

(3) Drying the fished seeds in a constant-temperature drying oven at 30-40 ℃ for 0.5-1.5 hours, and turning over the seeds frequently during the drying period;

(4) The dried seeds are poured into a concentration of

Soaking seeds in the rooting powder solution, frequently stirring the seeds in the seed soaking process, and filtering the seeds after 3 to 5 hours of seed soaking;

(5) And (4) airing the filtered seeds outdoors, and stopping airing when the moisture on the surfaces of the seeds is evaporated, and entering a sowing link.

The invention has the beneficial effects that:

(1) The treatment effect is good: the seeds treated by the method can form a lawn 14-23 days in advance; the underground biomass increased 57.76% -193.93% 38 days after sowing.

(2) The material for treating seeds is simple and low in cost: only one constant-temperature drying box, two chemicals and a plurality of sieves, basins or barrels are needed.

(3) The treatment period is short, and the whole treatment period comprises only 15-16 hours of airing.

(4) And (3) light pollution: the liquid medicine after treating the seeds each time can be recycled after adding the tonic, so that the raw materials are saved and the environment is protected.

(5) Is convenient for batch production: the invention has low cost and simple process, and is convenient for batch production.
