1. The soles of tennis shoes are hard or hard

The soles of tennis shoes are generally hard materials. This is because the athletes need to stop quickly when playing tennis, and stop slippery in time. tennis movements are very supportive of footsteps. Therefore, the soles of tennis shoes are generally highly resistantThe material of rubber grinding is generally good at wear resistance and compressive resistance. The only disadvantage is that it will be very hard when it is worn. Its density and hardness are high, which is conducive to the athletes to retreat and improve their flexibility.

If the soles of tennis shoes are soft, it will cause athletes to fall during strenuous exercise. Therefore, the biggest design requirements of tennis shoes are sports protection. Its sole is made of hard and wear -resistant rubber.With different styles of tennis shoes.

2. Why the soles of tennis shoes are hard

tennis players generally do not feel the soles are hard. Because they wear tennis shoes for a long time to shuttle in different venues, and then need to run frequently on the field, the friction is important to their soles. At the same timeIt is very tight. Its package design and hard rubber sole can protect our feet.

The design of the package can protect the ankles. The athletes' small broken steps, sprints, and Running actions have the risk of stoming ankle. Although this close design makes you not adapt to it when you first wear it, you can avoid it well.Injury occurs.

tennis sole wear -resistant materials can increase friction and make athletes safer during exercise. Some tennis shoes are treated with round suction lines on the forefoot part.The ground improves the turnover efficiency. If the soles are soft, the athletes can easily fall.

Second, community green management and maintenance plan

1Watering

Different varieties of plants require different water volume,,Different seasons of plants are also different in water,,Make it according to the specific situation when watering.Generally, willow should be poured more,,Pine cypress is not suitable for pouring,,Newly planted small trees should also be poured appropriately,,The amount of watering should be adjusted appropriately under different climate conditions,,summer temperature is high, evaporates fast,,The amount of watering should be increased appropriately;;After the autumn, the sun is weakened,,If you evaporate less, you can pour less appropriately,,The rainy weather, the semi -shade environment can be poured less or not poured.

Generally, trees are planted every year3As well as4As well as5As well as6As well as9As well as11Pour water once a month,,Pour through once when watering,,Avoid only wet surface soil.Joemu is at least continuous watering3 ~ 5Year,,shrub5Year,,If the soil is not good, it should be extended,,After the trees grow up, you can reduce the number of watering times year by year,,After growing into a big tree, you can not water it or only pour in a year1 ~ 2Second-rate.

2, Fertilize

Plants grow in a fixed position for a long time,,Absorb nutrient around the place all year round,,If you do not replenish in time,,It will cause nutrients to reduce or exhaust their nutrients,,Affects the normal growth of trees:::Timely fertilization has become an important part of maintenance work.There are many types of plants in the green space in the community,,When fertilizing, different Fertilizers and different dosage should be selected according to different plant varieties and growth stages.When fertilizing, Fertilizer should be buried in Fertilizer10 ~ 40cmDeep soil layer,,In order to facilitate the infiltration of Fertilizers into the ground,,Reduce the amount of Fertilizer.

3, Plastic Surgery Pruning

Plastic trimming is to ensure a good tree shape,,Effective means to improve the effect of rewarding concept,,It is also an important part of maintenance work.The basic methods are mainly sparse branches, short -cutting, and peeling buds.

Sparse branches,,It is to cut part of the dense, useless, and poor growth branches,,To ensure strong trees,,Expand the custard,,Form a beautiful tree posture.When sparse branches, we must follow the order of first big branches, rear branches, and then small branches,,Consider the current tree shape and long -term skeleton.Cut the mouth or saw the mouth close to the mother branch,,Can't stay,,In order to facilitate wound healing.The reserved leadership branches must be upright and strong,,The main branch oblique angle and direction are good,,Large branches and small branches are expanded reasonably,,Trees are short.

Short,,It is to cut the branches from the middle,,To suppress its growth,,Promote the balance of the main branches.Pay attention to the direction of the buds under the cut of the mouth,,General buds of buds out of the branches,,Expand the custard,,So the buds under the cut mouth should be full and strong buds,,To ensure the growth of the branches.

Sprout,,Is the newly issued tender bud or tender branches and roots.,,To reduce the useless young branches,,Make nutrients concentrated.In essence, it can be understood as a form of sparse branches,,It is necessary for the newly planted young trees and short trimming young trees.

4, Weeding, loose soil

Weeding is to remove the weeds in the green space,,Keep the green space tidy,,Reduce weeds and trees to compete for water Fertilizer,,It is conducive to the growth of trees;;at the same time,,It also cleared some of the latent places of diseases and insects,,Reduce the chance of pests and insect pests.The pine soil is loosened on the surface of the soil,,To increase the breathability of the soil,,Real the effect of retention, breathable, and temperature increase.

5, Prevention and treatment of diseases and insect pests

The prevention and treatment of diseased pests should formulate targeted measures according to the green space plant varieties and local pests in the local area.,,Mainly prevent prevention,,Comprehensive governance.spring is the season of pests and insect pests,,Must focus on governance;;In summer, we mainly pay attention;;Pay attention to killing overwinter eggs in autumn and winter,,Lay the foundation for the prevention and control of the year.

(1)Tree:Watering, fertilizing, loose soil, trimming2Subject to the annual spray3Second-rate;

(2)Hea: Headi:Regular watering, fertilization, trimming3Subject to the annual spray3Second-rate;

(3)lawn:Watering, fertilization, weeding on schedule, spray medicine every year2Second-rate.

3. Who is the greening of the community?
