Is it better to plant watermelon black mulch or white mulch in spring

White mulch is good. Good light transmission and high temperature. Black mulch film is easy to die when it encounters low temperature and rain.

Advantages: 1. Strong fertilizer retention ability. The soil covered with black mulch film is in a normal cycle state due to the stable change of soil temperature, and the measurement shows that:

The nutritional indexes such as total nitrogen, organic matter, available potassium and alkali hydrolyzable nitrogen in the soil under black film mulching cultivated crops were improved to varying degrees compared with those covered with transparent film.

Second, the water retention capacity is good. According to the test, the water content of 5 cm below the ground after black mulch film is 4-10% higher than that of transparent film, whether it is two days after mulching or 35 days after mulching.

3. Prevent adverse effects. The black mulch film has low light transmittance and low radiant heat transmission, so it can make the daily variation of soil temperature of the covered soil small. According to the experiment, the soil temperature of the soil covered with black film is 1-3 lower than that of transparent film during the peak growth period of the plant.

Due to the small warming amplitude, it is conducive to promoting the normal growth of crop roots.

Fourth, increase output. Because the soil temperature of black mulch film is less than that of transparent film, especially late-ripening watermelon, the early yield or total yield can be higher than that of transparent film after covering black film.

5. Inhibit weeds. Grass damage is a serious problem when using transparent film mulching, after switching to agricultural black mulch, ground weeds are difficult to grow due to insufficient light conditions, and the measurement shows that after covering the black film with a light transmittance of 5%, the soil is almost free of weeds after one month. When mulched with 10% light transmittance, weeds grow in the soil, but the growth is weak and does not cause disasters.

Disadvantages: The heating is not as fast as the white mulch. At present, it is difficult to degrade.

It is best to use both mulches together.

The black mulch film is covered on the bottom layer to achieve the weeding effect, and the white mulch film is covered on the black film to achieve the effect of warming.

Now the season is about to enter the peak period of watermelon, watermelon is one of the must-choose fruits for many people in summer, watermelon has a very wide planting area in our country. Nowadays, most of the watermelons planted are mainly planted in greenhouses, which can better control the temperature and humidity and promote the growth of watermelons. So how to grow watermelons in greenhouses?

1. Planting soil.

Watermelons, whether planted in greenhouses or cultivated in the open field, must be rotated, and cannot be combined with cucumbers, bitter gourds and other melon vegetables to prevent the harm of soil-borne diseases. We need to choose a high terrain, normal drainage and irrigation, deep and soft plots to build greenhouses. Then before sowing in spring, the soil should be turned about 25 cm deep to destroy the overwintering place of the fungus and pest.

Use the low temperature environment to freeze the pests to death, and then dig a melon trench to facilitate the root growth of the watermelon plant. Then apply sufficient basal fertilizer, control the amount according to soil fertility, mainly farmhouse fertilizer, and finally make furrows to prepare for sowing.

2. Reproduction methods.

The propagation method of watermelon in the greenhouse is generally based on sowing and grafting, and the most used is sowing and propagation. Seeds should be selected with high yield, strong disease resistance and no pests and diseases. Then place the seeds in warm water at about 50 degrees and stir them for about 8 parts.

Then, when the water temperature gradually decreases, the water should be picked up in time for about half an hour. Then use trisodium phosphate and other solutions to carry out seed dressing, clean and then air dry after seed dressing, wrap it with a damp cloth and put it at a temperature of about 26 degrees to do germination work. During the soaking period, a certain humidity should be reported, and when about 85% of the seeds have germinated, they can be sown.

3. Sow seeds at the right time.

When the soil temperature is above 16 degrees, it is ready for planting. Before sowing, dig a sowing ditch, water it thoroughly, and then put the seeds in the middle of the sowing furrow. Each sowing hole can be put into a seed, and after sowing, cover with soil and cover film.

Before the seedlings emerge, the temperature should be controlled at about 22 degrees Celsius and watered regularly. When the seedlings are unearthed, the mulch film is uncovered, and ventilation and cooling work are carried out to avoid high temperature and high humidity causing the seedlings to grow. After the seedlings have their first true leaves, make sure there is enough light.

Before planting, it is necessary to do a good job in the field of land preparation and fertilization, dig planting holes, and water enough to create a suitable growth environment for seedlings.

4. Field management.

Water and fertilizer are substances that require a relatively large amount of watermelon in the growth. We should reasonably control the amount of water and fertilizer according to the growth of watermelon and the weather. Among them, it should be noted that when the watermelon enters the vine extension stage and the young fruit stage, it is necessary to chase the water-soluble fertilizer of the fertile leaves in time to meet the sufficient nutrition needed for the growth of the watermelon.

Then it is necessary to do a good job of pruning to prevent the number of melon vines from being too large, resulting in overlapping and affecting each other's growth. It can also reduce nutrient consumption and concentrate nutrients on flowers and fruits. Finally, it is necessary to use the greenhouse to properly adjust the temperature, humidity and light to avoid environmental discomfort and affect the growth of watermelon.

Both are available. Black mulch film, white mulch film are very common, the number of times used is also a lot, the two mulch film colors have certain advantages, now we commonly use two-color mulch. This mulch is silver-grey on one side and black on the other, which has two advantages over monochrome mulch.

Silver-gray is the front, after the film can increase the ground temperature, and we all know that some silver-gray strips will be hung in the greenhouse to prevent insects, and the silver-gray plastic film is the same, which can avoid aphids, planthoppers and other insect pests, which is a characteristic that white mulch or black mulch film does not have. The black side is next to the soil, and it uses opacity to prevent the growth of weeds.

Personally, I think this two-color mulch is better than the monochrome mulch and can be used all year round. Farmers can also choose the mulch film according to the planting season or the greenhouse, white or black mulch should be selected according to the planting season, white is suitable for winter or early spring, black is not recommended.

Dapeng grows watermelons, and it is better to use black mulch, because black mulch is thicker and has a better insulation effect than white mulch! It can also effectively stop the growth of grass, so that watermelon seedlings can absorb nutrients well! Hope it helps!

It is good to use black mulch film to plant watermelons, because the light in the greenhouse itself is insufficient, so it is easy to absorb light and maintain the temperature of the soil.

It is good to use black mulch, which is good for absorbing light and increasing the temperature of weeding.

The color of the mulch used when growing watermelons is usually black or transparent instead of white. The original stupid celebration is as follows:

Transparent mulch film can increase the ground temperature, make the growing season of watermelon prolong, and at the same time can increase soil moisture, which is conducive to the growth of watermelon.

The white mulch film reflects the sun's rays, which is not conducive to the heating of the soil, so it is not suitable for growing watermelons. Moreover, white mulch film is more likely to be blown by the sun and wind than black and transparent mulch film, and the service life is relatively short.

Facility cultivation mulching is an important auxiliary means for vegetable farmers to improve vegetable yield in agricultural production! It is understood that the soil temperature of vegetable planting mulch film is 2-4 degrees higher than that of the soil that is not covered with mulch, and for the northern region, the solar greenhouse winter planting vegetable mulch film can improve the ground temperature, vegetable safety overwintering, increase yield, early listing and other advantages. At the same time, plastic film mulching can maintain soil moisture and inhibit the growth of weeds.

There are two kinds of mulch film commonly used in the production and management process of vegetable farmers, one is white transparent mulch; The other is black opaque mulch, of course, according to the habits of vegetable farmers, red, green, silver and other colors of mulch, but the amount is relatively small. For these two kinds of mulch, vegetable farmers want to know which mulch is better to cover in winter vegetable planting, and how to cover the mulch film better?

1. White mulch, its light transmittance is good, the ground temperature can be increased by 2-4 after covering, and the scope of application is wide, mainly used for vegetables, melons and other light-loving vegetables, with high yield and good quality. However, white mulch film also has disadvantages, that is, it is worse than black mulch film in inhibiting the growth of weeds, and weeds can make full use of light for photosynthesis, so that weeds grow faster.

2. Black mulch, its light transmittance is only 10%, under sunlight, it warms up quickly, has a good moisturizing effect, moistens the soil, and loses less water, but the heat transmitted to the soil is less, and its opacity can effectively inhibit the germination and growth of weeds, which can be used in areas with many weeds and save the cost of weeding.

Is it better to cover vegetables with white mulch or black mulch in winter?

1. In winter, the vegetable planting in the solar greenhouse covers the black mulch, the temperature difference between day and night is smaller than that of the white mulch, the ground temperature is relatively stable, the root system of the plant is deep, not easy to age, the stress resistance is strong, the plant grows vigorously, and the fruit setting ability is strong, which is suitable for the planting of eggplant fruits and melons and fruits with long growth cycle.

2. The light transmittance of black mulch film is low, because it is almost opaque, weeds can not germinate and photosynthesize, the effect of weed-prevention is remarkable, white mulch film is just the opposite, winter vegetable planting covers black mulch film without spraying herbicides, avoiding soil compaction, soil permeability is good, conducive to soil microbial activities, promoting root growth, and avoiding the occurrence of various soil-borne diseases.

3. Winter greenhouse planting vegetables covered with black mulch film has a good water retention effect, which can keep the soil moist for a long time, avoid the occurrence of diseases caused by excessive indoor humidity caused by watering too frequently, and the white plastic film has strong light transmittance, and the surface soil dries quickly, affecting the normal growth of the surface root system.

Therefore, winter vegetable planting covering black mulch film is better than white mulch, Shouguang Agricultural Technology Extension Association recommends vegetable farmers to use light subtractive cultivation technology - no ploughing, no base fertilizer, no pulling, no sterilization, covering black mulch, rooting agent strong rooting, growth cycle flushing application of all-element water-soluble fertilizer, no spraying, no flowering, high yield, good quality, early market, low cost!

Both can be used, spread the black film on the ground to prevent the growth of weeds, attach the white film to the black film to help keep warm, and the watermelon will grow very well.

It's still best to use white film. Because watermelons have high requirements for temperature and humidity, white film should be used.

The black film is better because it can better absorb sunlight and make the plant grow faster, and the black film also ensures that the heat of the plant is not dissipated, so the melon is sweeter and larger.

Summary. The black mulch film used for planting corn is better than the white mulch, and the absorption and utilization of crops cultivated under the black mulch film for the organic matter in the soil, available potassium and other nutritional indicators are higher than that of the white mulch.

The black mulch film used for planting corn is better than the white mulch film, and the crops cultivated under the black mulch film have a higher degree of absorption and utilization than the white mulch film for the organic matter in the soil, the nutrients such as the fast-available potassium and other nutrients.

Under the cover of black mulch, it is better than white mulch film in terms of yield increase, fertilizer retention, water retention, etc., and black mulch film is good for absorbing heat radiation and has great economic benefits.

It is recommended to use black mulch covering.

Hello dear<>

The answer you're looking for: black mulch for growing watermelons. This mountain shoot is because the black mulch film can absorb more solar energy per acre of Taihuai, so that the soil temperature increases, thereby increasing the growth rate and yield of watermelon.

In addition, black mulch can also prevent the growth of weeds and reduce the occurrence of pests and diseases. Although white mulch film can also be used, it is not as good as black mulch to absorb solar energy, which is not conducive to raising soil temperature and promoting watermelon growth. Therefore, it is recommended to use black mulch when growing watermelons, which can improve the yield and quality of watermelons.

It is good to plant watermelon mulch film because it can effectively reduce water evaporation, maintain soil moisture, and is conducive to watermelon growth.

1.Mulch film can effectively reduce water evaporation, maintain soil moisture, and be conducive to the growth of watermelon.

2.Mulch film can inhibit the growth of weeds, reduce the hindrance in the picking process, and promote the growth of watermelon.

3.The plastic film can maintain the soil temperature, which is conducive to the germination and growth of watermelon seeds.

4.Mulch film can reduce soil erosion and soil erosion, and reduce the waste of water resources.

Cons: 1Plastic film will reduce soil aeration and affect the soil ecological environment.

2.The shed is film**, the cost of use is high, and it is not suitable for small-scale planting.

3.The chemicals used in the production of mulch film can contaminate the soil.

4.Mulch film is susceptible to rainfall, wind and animal damage and has a limited lifespan.

Summary. Because the black mulch film can absorb the heat of the sun, speed up the growth of watermelon, and can effectively protect watermelon from pests and diseases. However, if the soil quality is good, you can leave the mulch blank, but pay attention to the moisture of the soil and prevent the occurrence of pests and diseases.

Hello kiss, I'm glad to answer for you, kiss, generally speaking, it is better to plant watermelons in the open air with black mulch in April.

Because the black mulch film can absorb the heat of the sun, speed up the growth of watermelon, and can effectively protect watermelon from pests and diseases. However, if the soil quality is good, you can not use mulch, but you should pay attention to the moisture of the soil and prevent the occurrence of pests and diseases.
