Seed sowing method of clover

Clover (clover is a rare variety of clover) is a general term for many herbs with three finger-shaped compound leaves. It mainly includes some species of Trifolium, Medicago sativa and Oxalis in Leguminosae (Leguminosae). The method of reproduction is mainly sown and propagated. Let's take a look at the seed sowing method of clover.

Clover sowing time

Clover can be sowed in spring or autumn, spring in late March, autumn in mid-September, autumn sowing in the south, spring sowing in the north, and sowing in summer, but the topsoil must be moist or shaded with mulch after sowing. The suitable sowing rate of clover is 8 grams per square meter, and there are 1400 and 2000 seeds per gram of clover. Theoretically, one seed per square centimeter of soil can meet the needs of forming a flat, and the actual sowing rate is larger than the theoretical sowing amount.

Sowing method of clover

When sowing clover, divide the seeds equally according to the area of the land and the determined sowing amount, mix the seeds with dry soil or fine river sand, and sow them manually. If the lawn is planted in a large area, it can be sown with a whirlwind seeder with a depth of 1 cm. After the seeds are sowed into the turf bed, the seeds can be raked into the soil with lawn rakes, or covered with fertile soil or matrix.

Management of clover after sowing

The main results are as follows: 1. The management before the formation of the flat: the clover grows slowly at the seedling stage. After the seeds are sown in the turf bed, sprinkler irrigation can be carried out if the sprinkler irrigation system is installed in advance, and the self-made sprinkler can be used for artificial irrigation if there is no sprinkler irrigation system. Spray every morning or evening, always keep the surface of the turf bed moist until emergence, after emergence can reduce the number of spraying, but still need careful management, seedling management of about 30 to 50 days, in addition to pay attention to watering to keep the turf bed moist, but also to remove weeds at any time, mainly manual pulling, to prevent weed harm.

2. Management after the formation of the flat: because of its strong invasiveness, clover does not need to carry out intermediate ploughing and weeding, because nitrogen-fixing rhizobium can absorb nitrogen in the air and transform into a form that can be used by plants. Therefore, fertilization is mainly phosphorus and potassium fertilizer, no or less nitrogen fertilizer. In the growing season and overwintering, it is necessary to provide sufficient water to ensure exuberant growth and safe overwintering. Before the height of summer, it can be cut once and watered enough to keep the plant green. Cut it again before overwintering and pour enough winter water. In this way, when it turns green in the coming year, there will be no withered and yellow branches and leaves on the flat surface. Anti-pollution, anti-disease and insect pests are strong, diseases and insect pests are less, when found leafhoppers, weevil, ground tiger and other pests, you can use dimethoate, dichlorvos and other spray.
