1. Is the Nutritional soil for planting vegetables?

Nutritional native dishes are not poisonous.Nutritional soil dishes are not poisonous. The composition of nutrient soil is perlite, vermiculite and Fertilizer.It can provide sufficient nutrients for the soil. Vegetable leaves will grow more green. Planes can strengthen the breathability of the soil, strengthen the absorption of the roots of the vegetable leaves, drainage the rainy season, and effectively promote the growth of vegetables.

When the Nutritional soil is used, it needs to be stirred with the soil after use.Put the Nutritional soil into the bottom of the Flower pot and cover a layer of thin sand to avoid direct contact with the seeds and vegetable seedlings.The nutrient soil is sufficient, and the use of directly can cause burns at the root of vegetable leaves.After planting vegetables, watering is required to promote the absorption of the root.

When planting vegetables indoors, the soil needs to be guaranteed. The soil contains a large amount of bacteria and heavy metal substances, which will breed a lot of bacteria.After soaking the soil with potassium permanganate solution, it is necessary to use sterilization and disinfection treatment, and use some larger containers to meet the growth space of vegetables.

When planting vegetables, it is necessary to ensure that the sun is sufficient, and the vegetables can be maintained on the balcony.Insufficient light, the leaves of the vegetables grow slowly, the leaves become dry, apply fertilization in time, and make a good nutrient supplement for the soil.vegetables need to be watered in time to ensure the moistness of the soil and make up for water to replenish in order to promote the growth of vegetables.

2. Can vegetables only use Nutritional soil?

If it is a special Nutritional soil for vegetables, then vegetables can also be used to use Nutritional soil directly.However, most of them are general nutrients on the market, so Nutritional soil dishes cannot be used alone.Nutritional soil was originally used for flowers and grass. It contains a Chemical Fertilizer with high nutritional ingredients. Some alkali is relatively strong. It is not suitable for seed growth to germinate, or tender seedlings. It is not easy to burn the seedlings.Nutritional soil should avoid direct contact with vegetable seedlings, otherwise it will cause roots.

three,Nutritional soilWhy plant vegetables, vegetable seedlings will die

Nutrition soil can make plants stronger and produce more vegetables.This is because the Nutritional soil is fertilized by scientific formula, and the nutrition inside is completely reasonable.This is like breeding households to gain weight faster than feeding livestock and poultry fed with feed.Due to the configuration of Nutritional soil, it costs more time and work. Generally, Nutritional soil is only used for vegetable seedlings.Most of the dishes caused by Nutritional soil dishes are due to the problem of fertilization and watering.

1. Outdoor folding knife or straight knife

1. The advantages and disadvantages of straight knives

The knife, as the name suggests, is a knife that will not be folded.Therefore, the straight knife is different from the folding knife. It does not have a connection point, and the handle is integrated with the blade.It is for this reason that the straight knife is much stronger than the folding knife, especially the whole keel's straight knife.

The connection point on the folding knife greatly weakens the solid of the Tool.The sturdy straight knife can be used for Outdoor tasks such as knocking, fire, leverage, hammering.However, in terms of carrying, the straight knife has the advantage of folding knives.Straight knife requires a strong and reliable scabbard to store tools.Another disadvantage of a straight knife is that they are heavier than folding knives.

2. The advantages and disadvantages of folding knife

The blade of the folding knife can be folded into the handle so that the folding knife can be carried in the pocket.This method reduces the size of the Tool and hides a sharp blade.However, the main axis link point in the folding knife also has disadvantages. When the pressure applied is too large, it may break.That is, why can't you use the folding knife for any reason in the wild.

The main advantage of the folding knife is that it is easy to carry and use comprehensive use.However, if it is Outdoor survival, it is not recommended to use a folding knife.Because the folding knife is not strong enough and reliable, it cannot become the main survival Tool.

Therefore, for daily use, a small fold is good.For Outdoor use, remember to use a straight knife, straight knife is always a safer and stronger choice.

2. How to choose Outdoor survival knives

1. Size selection

A straight knife suitable for Outdoor survival should be 10-15 cm in length.The size of the Outdoor knife should not be too large.The too long knife will lead to the overall weight of the knife. It takes physical strength to take it in the hand and occupy the space in the bag. It is not flexible and laborious to use. It is not conducive to long -distance Outdoor survival adventures.Not too small.Although the palm knife is easy to carry, it is not very useful.Cutting branches and cutting ropes are more laborious. It is easy to break accidentally, and it is very ribs.In comparison, medium -length knives can do some relatively fine tasks, but also be competent for some heavy tasks.

2, knife type selection

A whole keel's straight knife is the best choice for Outdoor knives.The knife of the folding knife can be folded into the handle, which is more safe and easy to carry.But this biggest advantage is the biggest disadvantage for Outdoor survival use.As we all know, as long as it is stitching, it will be more likely to cause damage.The folding knife's hollow handle and folding shaft are obviously weak parts that are easy to break.There is no integrated knife body for activity components, which is obviously more suitable for Outdoor survival.The straight knife of the keels is better resistant, can withstand greater use intensity, the overall force is more balanced, and it can withstand high -intensity use.

3. Blade selection

It is best to choose a bladeless blade.Although there is a jagged blade, although it looks very cool, this design is very bad for Outdoor knives.Although the tooth blade can help a little on the cutting rope, but in addition, this design is very "dragging the legs": if the tooth blade is blunt, you need to use a specific grinding Tool to polish, one groove, and a groove.It is very troublesome; at the same time, the Outdoor knife with a tooth blade has also been greatly reduced, because the tooth blade cannot do anything else except cutting the rope.

4. Handle selection

For the choice of the handle, remember two words: non -slip, comfortable.The anti -skid of the Outdoor knife handle is very important. This allows you no matter what kind of environment you are, you don't have to worry about the sword on your hand suddenly slipped away.As for the grip comfort of the handle, you can only try to try the feel when choosing a Tool.

5. Material selection

Compared with other materials, Damascus Steel's knife is rigid and soft, and the blade is better.

1. The correct way to ride a helmet

cycling motion is also called a bicycle motion. It is a kind of sport that uses bicycles as a Tool race. As a sport, it is important to do a good job of safety protection.The safety of the head can also reduce the resistance through special design and improve the rider's achievements.However, the Bicycle helmet is not just worn casually. You also have to master the correct method of wear. So how do you wear a cycling helmet?

1. Open the band and sort out other accessories of the riding helmet to facilitate wear.

2. Put the level of the helmet on your head and slowly tighten the bundle until you feel comfortable.

3. Adjust the band below the ears and adjust the position of the band.

4. After the band is adjusted, tighten the band close to the chin and buckle the bundle band buckle ring.

5. After completing the above operations, make sure that the range of the helmet movement does not exceed 1 inch (1 inches = 2.54 cm). At the same time, it is guaranteed that the helmet without loosening the front helmet will not fall off and it means that you can wear it.

2. What are the precautions for wearing Bicycle helmets

1. After the helmet is worn correctly, it should be ensured that the front of the helmet should be a horizontal line above the eyebrow heart. The two sides are close to the temples, and the position of the helmet is not impartial.

2. Most out of control and collision are fell forward, so the helmet's wearing angle should not be too much leaning, the front of the helmet should be pressed to the eyebrows, do not expose the forehead, but too much forward will cover the sight.As a result, the helmet fixed mechanism cannot be well fixed, and it is easy to cause a helmet to move or wear uncomfortable in the bumps.

3. The buckle position also has a direct impact on the comfort of the helmet. The correct position of the "Y" font buckle should be located at about 5-10cm below the ear.Tighterness will affect comfort.

4. After wearing a helmet, you should pull down the loose regulator in the back of the head, so that the regulator can fully wrap the back of the head and then adjust the tightness.Then, the twisting knob allows the headband to give a certain pressure beam and tighten the head. It is better to shake the helmet with both hands without loosening.

5. The tightness of the band of the chin is based on the standard of one finger, and Taisong will not be able to fix the position of the helmet.The helmet needs to be worn correctly to exert its greatest effect.

6. Regardless of whether or not you fall or collide, the cyclist should change the riding helmet every three years.Because even if the helmet has not collided, the sun exposure and sweat erosion can make the safety beam band aging, thereby weakening the surrounding fitting system and damaging the protection performance of the helmet.

3. What are the principle of protection of a helmet

The principle of cycling helmet is to play a protective role by absorbing the impact of collision in the inner layer of the foam. Each cycling helmet hasMaterial orEPP (foam polypropylene) foamIn the inner layer, when the accident occurs, the inner layer of the foam will buffer collision to reduce accident damage.

It should be noted that the cycling helmet made of EPS (foam polystyrene) material, once the EPS bubble is crushed and deformed in the accident, it cannot be recovered and reused.The inner helmet made from EPP (foam polypropylene) foam can be restored to use again after being hit, but the intensity of its absorption impact is far less than the EPS bubble. ThereforeRiding a helmet, after all, safety is the first.
