Method for rapidly propagating Zoysia matrella to form lawns in large scale

Abstract

The invention discloses a method for rapidly propagating Zoysia matrella to form lawns in a large scale, belonging to the technical field of cultivating lawns. The method provided by the invention comprises the following steps of: (1) ploughing soil and pouring water to wet the soil; after weeds are germinated, spraying herbicide and tightly pressing; paving a paddy layer with the thickness of 1-3 cm on the soil layer and then paving yellow sand layer with the thickness of 2-4 cm and mud with the thickness of 2-4 cm in sequence to form a lawn bed; (2) chopping creeping stems of the Zoysia matrella lawns and spraying rooting agent; uniformly sowing the stems into a lawn bed; lightly crushing grass stems and pouring water to accelerate rooting; (3) alternatively spraying 30-60 ml of glyphosate with the concentration of 20% and 300-500 ml of paraquat with the concentration of 10% into each acre every 10-20 days to remove weeds; spraying water for 2-3 times every day and applying additional fertilizer into the lawns to accelerate growth; after three months, producing the lawns. The method provided by the invention is simple and practical, combines the characteristic that the Zoysia matrella grows fast and utilizes traditional multiple technologies for propagating and cultivating lawns to optimize; the method can cultivate and produce lawns in a large scale, and has a fast lawn producing speed and a high lawn quality.

Description

technical field [0001] The invention relates to a lawn cultivation technology, in particular to a large-scale and rapid propagation method of manila grass. Background technique [0002] Manila grass, also known as Zoysia ditch leaves, is Zoysia grass of the Gramineae family. It is a perennial herb with rhizomes, with transverse rhizomes and stolons. The leaves belong to the semi-thin leaf type in Zoysia genus, which is slightly cold-resistant, strong in drought resistance, and resistant to barrenness. It is very suitable for extensive planting and cultivation in the central and southern regions of my country. Manila grass has a dense layer and is slightly resistant to trampling. The base of the rhizome is erect and has a certain degree of toughness and elasticity. Green grass, less pests and diseases, strong tillering ability, high coverage, high ornamental value, cultivated in deep fertile, well-drained soil, grows rapidly, and becomes flat quickly. There are few flowers,...

Problems solved by technology

[0003] The current lawn planting and cultivation modes are diversified. The lawn grown by soil cultivation is of high quality, easy to cut into pieces, hard and firm, and convenient for transportation. However, the birth rate of weeds cultivated by soil is high, which is easy to be infected by diseases and insect pests, and will cause soil damage. Loss; Soilless cultivation is a new cultivation technology in recent years, through the artificial cultivation of nutrient base for lawn propagation, basically overcome the defects of weeds, diseases and insect pests, etc., but the cost of completely using soilless nutrient base is too high, making the investment in lawn production larger

The use of sandy soil cultivation can facilitate lawn lawn, but the water retention of sandy soil cultivation is not as good as the substrate of soilless cultivation, and the strength of water and fertilizer is not as good as that of soil for soil cultivation. However, due to its low cost, convenient management, time-saving and labor-saving advantages , still has a great development prospect
