What fertilizer is used for lawn

Lawn is a kind of greening that we can often see, and most of the lawns are grasses. So, what kind of fertilizer does the lawn use?

What kind of fertilizer is used in the lawn?

The commonly used chemical fertilizers for lawns are nitrogen fertilizer, phosphate fertilizer, potash fertilizer, compound fertilizer, trace element fertilizer, etc., while organic fertilizers are manure, compost, green manure and cake fertilizer.

Second, how to fertilize the lawn?

1. Fertilization method

The common method of fertilizing the lawn is to spray or spread fertilizer.

(1) spraying is to dilute the fertilizer and water into a solution and spray it on the turf surface with sprinkler irrigation or other equipment tools.

(2) to spread fertilizer is to sprinkle all the fertilizer directly on the surface of the turf. Spread fertilizer evenly, uniform fertilization on the lawn is the key, uneven fertilization will destroy the uniformity of the lawn. In order to avoid excessive stimulation of plant growth caused by too much fertilization in a certain area, the fertilizer can be divided into several parts and scattered in different directions.

two。 Dosage

Generally, the annual nitrogen application rate of lawn with high maintenance level is 30 to 50 kg per mu, and that of lawn with low maintenance level is about 4 kg per mu. The amount of phosphorus fertilizer applied is generally 3 to 9 kg per mu for horizontal turf and 6 to 12 kg per mu for high conservation turf. The newly built lawn can apply 3 to 15 kilograms per mu. For Gramineae turfgrass, the ratio of nitrogen, phosphorus and potassium should be 4:3:2.

The amount of nitrogen fertilizer in the lawn should not be too large, otherwise it will cause the overgrowth of the lawn to increase the pruning times and reduce the ability of the lawn to resist environmental stress.

3. Times of fertilization

Fertilizer is applied twice a year, once in early spring and once in early autumn.

Fertilization in early spring can not only advance the green period, but also help to recover all kinds of damage to the lawn in the cold season as soon as possible, and form dense turf before the annual weeds get the suitable germination temperature. Fertilization at the end of August or early September can not only prolong the green period to the end of autumn or early winter, but also stimulate the tillering of turfgrass for two years and produce underground rhizomes. This kind of fertilization can create the best living conditions for good lawns, but it is disadvantageous to early weeds in summer.

The maintenance of lawn seems simple, but it should also be adapted to local conditions and the times. According to the specific analysis of the specific situation, the appropriate establishment method was selected according to the relevant conditions of the planting site, the planting time, the required turf formation time and the growth habits of turfgrass varieties.
