How to choose special fertilizer for lawn? What fertilizers are used for growing grass?

Generally, lawns are mostly long-lasting compound fertilizers rich in organic fertilizers. Most of the raw materials come from plant waste and decaying from garbage.

According to the nutrient needs and fertilization time of the lawn at different times, the fertilizer can be divided into basal fertilizer, seed fertilizer and top dressing.

1) Apply basal fertilizer.

The fertilizer is spread on the ground with a manure spreader before sowing or transplanting, and the fertilizer is deeply covered in the soil during ploughing. Or use a plough-mounted fertilizer applicator to apply fertilizer into the furrow when ploughing.

2) Seed fertilization.

At the time of sowing, seeds and fertilizer are sown into the soil at the same time. In the past, mixed application methods of seed and fertilizer were mostly used, and in recent years, more reasonable seed and fertilizer application methods such as lateral deep application and positive deep application have been widely used.

3) Apply top dressing.

During the growth of the lawn, apply fertilizer near the roots of the lawn; Or use the spray method to apply water-soluble nutrients (foliar fertilizer) to the foliar surface of turfgrass, which is called extra-root top dressing.

Lawn fertilization should be based on basal fertilizer. In addition to sandy soils, it should be supplemented by top dressing of nutrients including trace elements. Generally, the soluble nitrogen of sandy soil is easy to leach, so the number of fertilization should be more, and long-term nitrogen fertilizer should be the main fertilizer.

Depending on the dosage form of fertilizer and the needs of lawn plants, there are usually three methods: spreading, burrowing and spraying. Dry granular or powdered fertilizers can be sprinkled or hole-applied, and liquid fertilizers or water-soluble silty fertilizers can be sprayed.

You can choose Huatian Shengde organic fertilizer, a large number of lawn special fertilizer can effectively enhance the plant disease resistance and stress resistance.

The general base fertilizer for planting grass is plant ash, and plant ash mainly contains potassium fertilizer.

What is the best fertilizer to apply during the planting process depends on what grass you plant, some grasses need more nitrogen fertilizer, some grasses need more phosphorus fertilizer, and some grasses need more potassium fertilizer.

If you want to plant grass well, you must first understand the characteristics of grass seeds, which kind of fertilizer is needed in what period, and targeted fertilization can be carried out according to different periods, which is not only conducive to the growth of grass, but also can reasonably save fertilizer.

At the same time, it is necessary to test the planting land to see the content of various nutrients in the current land, and then carry out phased fertilization with the characteristics of plants.

The commonly used chemical fertilizers for lawns are nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, compound fertilizers, trace element fertilizers, etc.; Organic fertilizers are manure fertilizer, compost fertilizer, green manure, and cake fertilizer.

Nitrogen-based fertilizers, such as Bika high-nitrogen water-soluble fertilizers, should be used to promote the flourishing of branches and leaves.

Due to the large population and high density of the lawn, in order to make it grow vigorously and improve its anti-epidemic ability, the content of nitrogen, phosphorus, potassium and trace elements in the soil can be tested frequently when conditions permit, and the fertility can be replenished in a timely manner. Fertilization should be done before watering or rain. It can be sprinkled with special fertilizer rooting type and insect resistance of Happy Forest Zhuangmei Lawn, providing comprehensive nutrients for the lawn, efficient rooting, and insect pests.

In general, the word green is 3 out of 1,000.

to five thousandths. Results in one week. Squatting seedlings can be appropriately increased.

As the temperature gradually increases, the mixed cold and warm lawn needs to be mowed and maintained in time to ensure the recovery and growth of warm-season grass. Bermuda mixed grass blanket or turf rolls, from March to June every year, need to do a good job of technical maintenance to achieve the beauty of the grass and the four seasons.

Evergreen effect. The main measures are as follows: 1. Strengthen the frequency of pruning, prune once a week from March to April, and prune once every half a month after mid-May, and control the height of ryegrass at about 2 cm to inhibit the growth of cold-season grass.

Long, providing growth space for the regreening of warm-season grasses, Bermuda grass and Lanyin No. 3 grass begin to resume growth in March every year, gradually replacing cool-season grasses. 2. Sectional fertilization, from March to May in the early stage, because ryegrass is still growing.

For a long time, fertilization is difficult to be absorbed by warm-season grasses, but will increase the amount of ryegrass pruning, and fertilization needs to be strictly controlled, and growth regulators can be used to inhibit the growth of cold-season grasses in special cases. The coverage rate of the warm-season grass is reached.

To more than 50%, a small amount of high-tower compound fertilizer can be used to ensure the nutrients of the bottom grass, 8-10 grams per square meter, and more watering after application or fertilization before rain to dissolve the fertilizer. 3. Strengthen daily maintenance and pay attention to pest control.

When necessary, professional pesticides can be used for pest control. 4. Other remedial measures: grass stem replanting, due to excessive trampling or damage caused by the death of warm-season grass, the phenomenon of alopecia areata, after the discovery can be timely from the better recovery of the warm season.

Take out part of the grass block for replanting, the diameter of the replanted grass block is 5-10 cm, plant at intervals, and keep watering once every 2 days in the early stage of root system to speed up the formation of the lawn.

The lawn soil should be mainly sandy. In areas with poor soil, well-rotted organic fertilizer should be added as base fertilizer, and the fertilizer should be evenly sprinkled and thoroughly mixed with the soil. The pH of the soil should generally be between, and the pH should be adjusted by applying superphosphate or lime to the pH of the soil pH.

After the soil quality is qualified, the thickness must also be qualified. The general soil thickness of the lawn is not less than 4 0 cm, and after deep ploughing, the larger debris and weed roots in the original soil should be removed. If there is too much debris in the soil, the original soil should be sieved or replaced.

Cohesive soils should be added with cinders or pebbles to increase soil permeability.

Although it seems that planting lawn has so strict soil requirements, but in fact, the requirements of lawn on soil are not high, as long as the soil of other plants can grow, basically meet this requirement, you can plant lawn, even if it is saline-alkali land, you can also plant alkali grass, salt-tolerant high fescue, etc. At present, most of the varieties we plant are grasses, such as tall fescue, early maturing grass, ryegrass, dogtooth root, knotweed, Manila, Bermuda, etc. Whether it is sandy soil, clay, loess, black soil, or gravel soil with stones, as long as there is water, it can grow.

However, when planting lawn, there are also some things to pay attention to, such as not accumulating water, sufficient sunlight, regular fertilization, etc., as long as you master a few key points of lawn planting methods, you can grow excellent turfgrass.

Regardless of the quality of the soil, there are many mixed turf varieties that can meet different requirements, so you don't have to worry too much.

To fertilize a lawn, we must first know the characteristics of the lawn's demand for different fertilizers. Nitrogen fertilizer plays a very important role in the life activity, color and quality of turf. In general, with the exception of legumes, most lawn plants must meet their nitrogen fertilizer needs.

The demand for potassium fertilizer in lawns is also different in different growth periods, and generally grasses require more potassium at the tillering stage.

Spring fertilization of lawns: AcaciaIn spring, organic fertilizers containing more nitrogen are mainly appliedThe variety and amount of fertilizer to be applied should be determined according to the use of the lawn, the variety and the water and fertilizer conditions of the soil. In general, the amount of fertilizer per mu of cool-season lawn is 20 27 kg, and the ratio of nitrogen, phosphorus and potassium is 5:

4：3；The amount of fertilizer per mu of warm-season lawn is 40 65 kg, and the ratio of nitrogen, phosphorus and potassium is 5:4

Due to the large population and high density of the lawn, in order to make it grow vigorously and improve its resistance to Tamp disease, the content of nitrogen, phosphorus, potassium and trace elements in the soil can be tested frequently under the condition of conditions, and the fertility can be replenished in a timely manner. Fertilization should be done before watering or rain. It can be sprinkled with special fertilizer rooting type and insect resistance of Happy Forest Zhuangmei Lawn, providing comprehensive nutrients for the lawn, efficient rooting and return, and repelling insect pests.

Lawn fertilization should be applied according to the growth of the grass or soil fertility.

The fertilizer is mainly nitrogen and potassium fertilizer, and it is advisable to apply less nitrogen fertilizer in summer and mainly potassium fertilizer. Organic fertilizer should be applied in winter, and thin fertilizer should be applied diligently when the source is cautious. Fertilization during the growing season should generally be combined with watering after one week of pruning.

Generally, cool-season lawns are 2 4 times a year, warm-season lawns are 2 3 times a crack year, and 1 3 times a year are sown in a year.

<> fertilization of the lawn can generally be fertilized by spraying or sprinkling, spraying is to first dissolve the fertilizer with water, then pour the fertilizer into the sprinkler irrigation equipment or other equipment, and finally spray the fertilizer on the lawn; Spreading is direct fertilization, that is, directly spreading fertilizer on the surface of the turf, but when fertilizing, pay attention to spreading fertilizer evenly, so as to maintain uniformity of grass in the lawn.

First, how to apply compound fertilizer to the lawn

1. Spraying: Mix the compound fertilizer into the water, and use sprinkler irrigation equipment or other equipment to spray the fertilizer on the surface of the turf after the fertilizer is dissolved.

2. Sprinkling: Sprinkle compound fertilizer directly on the surface of the turf, but pay attention to spreading the fertilizer evenly when sprinkling, so as not to damage the uniformity of the lawn.

Second, the application rate of compound fertilizer and other fertilizers

1. Compound fertilizer: the application rate is generally 15-20 kg per mu.

2. Diammonium phosphate: the application rate is generally 12-15 kg per mu.

3. Urea: The application rate is generally 10 kg per mu.

3. Precautions for fertilization

1. In spring and autumn, compound fertilizer is generally applied, and in summer, diammonium phosphophodiamidic acid, urea and other fertilizers are generally applied.

2. After entering the winter, the aboveground part of the grass in the lawn will wither and yellow, while the underground part will enter a dormant state, and fertilization will have no effect at this time.

3. When applying urea on the lawn, we should strive to be uniform (urea is generally suitable for top dressing), and can not be irrigated immediately after fertilization, let alone flooded with water, otherwise the nutrients in urea will sink deep into the soil, which will lead to a decline in fertilizer efficiency.

Compound fertilizer, organic fertilizer, can lawn also need sufficient nutrients, in order to grow good-looking.

Fu Na Ze Shirt Hefei is a fertilizer composed of two or more nutrientsIt is rich in nutrients and can promote the growth of the lawn well, but the nutrient burning components of the compound fertilizer are fixed, so when fertilizing the lawn, it is necessary to analyze and test the soil of the lawn, and then use it with other unit fertilizers to achieve twice the result with half the effort.

Organic fertilizer is derived from the remains of many plants and animals, after processing them,Harmful substances are removed, leaving substances with very high nutrient content, which can bring comprehensive nutrients to the growth of the lawn, and the effect of fertilization is kept very long, and the soil for planting lawn can be improved to better promote the growth of lawn.
