Planting method of Lucky Grass seed

Soil preparation: before planting, the lawn needs to be ploughed deeply, and the grass roots, tree stumps, construction waste and other sundries need to be cleaned up. Sowing: one seed can be sowed in each hole, the sowing depth is 1-1.5cm, and the soil is covered with 1cm, then watered to ensure that the soil surface is moist, or the seeds can be mixed with dry soil and sprinkled into the soil. Late management: timely removal of weeds, in the peak growth period and overwintering, the need for a cutting, which is conducive to the healthy growth of lucky grass.

I. Land preparation

Lucky grass seeds are relatively small, need fine soil preparation before planting, deep ploughing of the lawn, courtyard lawn construction, usually after the completion of the building, so the site will have mortar, bricks, cement, sand, tiles, decorative materials and other waste, need to remove tree stumps, grass roots, construction waste and other debris before soil preparation, and then use garden soil for backfilling.

Second, sowing seeds

Lucky grass seeds can be sowed in late March in spring or in mid-September in autumn, mainly in autumn in the south and spring in the north, and can be sowed in summer. After sowing, the surface soil needs to be moist. Cover can also be used for shading. There are about 1400-2000 seeds per gram of lucky grass, and the effect of forming a flat can be achieved by sowing 1 seed in each hole.

Third, sowing method

The seed sowing amount can be determined according to the plot area, the seeds can be mixed evenly with dry soil, and then sowed into the soil. If it is a large area of lawn, the cyclone seeder can be used for sowing. The suitable sowing depth of lucky grass is 1-1.5cm. After the seeds are sown into the turf bed, the seeds can be raked into the soil with lawn rakes, and then cover the topsoil of 1cm.

Fourth, watering

The main results are as follows: 1. Lucky grass grows slowly in the seedling stage, and the management of the lawn before completion is very important. After the seeds are sown into the turf bed, sprinkler irrigation can be carried out in time if sprinkler irrigation system is installed in advance, but if no sprinkler irrigation system is installed, self-made sprinkler can be used for sprinkler irrigation.

2. Spraying can be carried out every morning or evening to keep the surface of the turf bed moist until the seedlings emerge, and the times of spraying water can be reduced appropriately after emergence, but it still needs careful management. The seedling stage management is about 30-50 days, and weeds need to be removed in time to avoid weeds competing for seedling nutrition.

5. Fertilization

The main results are as follows: 1. After the completion of lucky grass lawn, because of its strong invasiveness, there is no need for intermediate ploughing and weeding, but nitrogen-fixing rhizobia can absorb nitrogen in the air and transform it into a form that can be used by plants, so more phosphate and potassium fertilizer can be applied, but less nitrogen fertilizer can be applied.

2. In the exuberant growing season and overwintering, it is necessary to supply sufficient water to ensure the vigorous growth and safety of the plant through the winter. It is beneficial to keep the plant green by cutting once before the height of summer and then watering enough water. Before overwintering, it is necessary to cut again and pour enough overwintering water, so that withered and yellow branches and leaves will not appear on the flat surface when it turns green in the second year.

VI. points for attention

The main results are as follows: 1. Lucky grass does not have high requirements for soil, can adapt to various types of soil, is more conducive to its growth in acidic soil, likes the environmental conditions of sunny, warm and good drainage, and grows slowly in arid climate. there is a small amount of death in the high temperature season.

2. Lucky grass is resistant to pruning and trampling, and its regeneration ability is very strong. After pruning and waiting for about 10 days, newer leaflets will grow. After high intensity trampling or crushing, it can resume growth after 3-5 days, and the cold tolerance is also strong. When the winter temperature drops to 0 ℃, a small amount of old leaves will be withered and yellow, and the leaflets on the main root will be close to the ground and stop growing, but will remain green. In the case of strong shade, it is easy to grow. It leads to poor growth and has a strong ability to resist diseases and insect pests and harmful gas pollution.
