Description

Device and method for modularized planting of creeping bentgrass lawn

technical field

The invention relates to a device and method for modularized planting of creeping bentgrass lawns, belonging to the technical field of lawn planting.

Background technique

Creeping bentgrass (Agrostisstolonifera L.), also known as bentgrass and Sijiqing. It is a typical cool-season perennial turfgrass, suitable for planting in cold, temperate and subtropical regions. It is widely used in sports venues such as golf greens and bowling alleys, as well as landscaping projects such as urban lawns and courtyard lawns. According to incomplete statistics, 75% of golf course greens in the world use creeping bentgrass to build lawns.

At present, creeping bentgrass lawns are mainly planted in sandy land, but the sandy soil has a large particle size and strong water permeability, and the water for irrigation cannot be well fixed on the roots of the grass, and the water is easy to lose, while creeping bentgrass needs to be grown in humid conditions. Therefore, the turf that is built on the sand needs frequent watering to form a high-quality turf, which leads to the following deficiencies: 1) Creeping bentgrass lawn maintenance needs to consume a lot of water resources , and its actual use only accounts for a very small part of the water consumption, and the utilization rate is low; 2) The irrigation pipe network and sprinkler nozzles are expensive, and the construction procedures are complicated. Since most of the pipe networks are buried underground, it is not convenient for the pipe network 3) The quality of lawn planted in sandy land is heavy, and it is inconvenient to carry as a whole. The site for lawn planting cannot be removed quickly and reserved for other purposes. .

The above-mentioned shortcomings of creeping bentgrass lawn planting limit its beautification function, leisure function and sports function to a great extent. Therefore, there is an urgent need for a new construction that can save water resources, facilitate maintenance and maximize its functions. planting method.

Contents of the invention

In order to overcome the shortcomings of current sandy land planting, the present invention proposes a creeping bentgrass lawn planting method that can save water resources, is easy to maintain and can fully exert its beautification, leisure and sports functions.

In order to achieve the above object, the present invention adopts the following technical solutions:

A modular device for building creeping bentgrass lawns, which consists of planting baskets and modular units;

The planting basket group is composed of a plurality of square baskets with a mesh structure along the sides and at the bottom; for the convenience of cultivation, the integrated planting basket group is preferably composed of 4-6 square baskets;

The modular unit is an open square water container with edges, and a supporting column fixed on the bottom of the module is arranged inside, and the height of the supporting column is consistent with the height of the module; the modular unit is divided into a plurality of small containers by the supporting column. Square area, each small square area matches the shape of a planting basket group, so as to realize the function of building multiple planting basket groups at the same time. In the planting device of the present invention, preferably, the modular unit is divided into 4 small square areas.

1.4 Creeping Bentgrass Modular Lawn Planting

(1) On September 25, 2014, the creeping bentgrass planting basket module with a nylon mesh length of about 2cm was taken out of the seedbed gently, and the fine sand on the surface of the root was washed away, and placed in the installed planting module respectively On, mow the grass to a height of 5cm.

(2) Pass water to the planting module to 1 cm below the bottom of the planting basket, so that the roots of the creeping bentgrass are immersed in water.

(3) Add oxygen to the planting module for 24 hours every 2 days, change the water every 15 days, add Hoagland nutrient solution in proportion after each water change, and cultivate until October 20, 2014, a total of 25 days.

(4) Prune the creeping bentgrass of the aerial part to a height of 10 cm every 5 days.

(5) Carry out disease and insect pest control according to common creeping bentgrass lawn method.

Example effect analysis

In this experiment, the lawn quality, coverage and root growth length are three commonly used indicators for evaluating the quality of lawns, and the creeping bentgrass modular planting lawn is comprehensively and quantitatively evaluated.

(1) Lawn appearance quality of the lawn: according to the NTEP lawn appearance quality scoring standard, the density, color, texture and uniformity of the lawn are scored on a scale of 1 to 9 (1 is the worst, 6 is acceptable, and 9 is the best). Evaluation of the appearance quality of creeping bentgrass modular established lawns.

(2) Lawn coverage: refers to the percentage of the coverage area of creeping bentgrass lawn to the total area of the planting site. The larger the data, the better the coverage.

(3) Root growth length: refers to the growth length of the creeping bentgrass root system in the planting module. The relationship between the root and the aboveground seedlings is proportional. The longer the root system, the better the grass growth.

The experiment was carried out on September 30, 2014 to measure and score the evaluation indicators of the creeping bentgrass lawn. After that, it was carried out every 5 days and evaluated 5 times. It ended on October 20, 2014, a total of 25 days.

It can be seen from Figure 6 that the lawn quality of creeping bentgrass turf is on the rise, both of which are above the acceptable level. The last measurement data reached 8.57, the lawn quality is good, and the last two data tend to be stable , indicating that the lawn quality remains good.

It can be seen from Figure 7 that the coverage of creeping bentgrass lawn is on the rise, reaching 88.2% on October 20. This trend is consistent with the trend of lawn quality, indicating that with the increase of lawn coverage, the quality of lawn is also better.

It can be seen from Figure 8 that the root growth length of creeping bentgrass turf fluctuates in the first 15 days. At this stage, there is a buffer adaptation period for creeping bentgrass turfgrass transplantation from the sandy seedbed to the planting module. Rapid growth indicates that the turfgrass grows well in the building blocks. The increase in the length of the root system promotes the supply of nutrients to the turfgrass, ensuring the healthy growth of the turfgrass and good lawn quality.

Note: The vertical line on the statistical value indicates the error value between statistical replicates.

Judging from the above three lawn quality evaluation indicators, creeping bentgrass grows well in the planting module, has good lawn quality and lawn coverage, and fully realizes the greening and beautifying functions of creeping bentgrass lawn.

The method proposed in this patent: the modularization of creeping bentgrass turf can not only meet the requirements of building an excellent turf, but also reduce the weight of the turf, facilitate the movement and speed up the growth. The invention provides a diversified innovation and beneficial supplement of the existing creeping bentgrass lawn establishment method.

Although the present invention has been described in detail with general descriptions and specific embodiments above, it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention. Therefore, the modifications or improvements made on the basis of not departing from the spirit of the present invention all belong to the protection scope of the present invention.
