Watermelon seedlings are generally transplanted into the ground for a few days to produce new roots?

Under suitable temperature and humidity environment, watermelon seeds can germinate and emerge 36-48 hours after planting.

The following measures can be taken to improve the survival rate of watermelon seedling planting:

1. Water management: watermelon seedlings have a large demand for water, so they should be watered frequently, but there should be no stagnant water.

2. Strengthen ventilation: It is necessary to strengthen ventilation to ensure air circulation, and not to let it be in a stuffy environment.

3. Temperature management: watermelon seedlings can grow vigorously in the environment of 16 22, and the temperature needs to be well controlled.

4. Reasonable top dressing: it likes fertilizer, but is not tolerant of thick fertilizer, and the diluted sea meal fertile fertilizer is applied in the five-leaf stage.

5. Proper light exposure: more exposure to astigmatism.

Under normal circumstances, after 5-7 days (transplanting) can give birth to new roots watermelon seedlings after transplanting, the root system is more fragile, at this time it is necessary to keep the soil slightly dry, you can use a watering can to spray water mist around the watermelon seedlings, so that the roots of the seedlings and the soil are more compact, so that the watermelon grows healthily. There are many pests and pathogens in the soil, and as the ground temperature rises, the occurrence of pests and diseases will be relatively early. The best solution before transplanting is to use Trim microbial agent to apply again, transplanting after 10 days, and at the same time, you can also apply microbial agent when watering after transplanting, the role of microbial agent is to eliminate the virus bacteria in the soil, reduce the incidence of cataplexy and stem base rot, eliminate soil compaction acidification, and provide a good growth environment for the root system.

The seedling stage of watermelon is also the key period of flower bud differentiation, and all the flower buds that make up the yield of watermelon are differentiated at the seedling stage. The focus of the seedling stage is not only to promote root growth, but also to promote flower bud differentiation. Boron:

Watermelon seedlings are generally transplanted into the ground **7 to 10 days** to produce new roots.

This depends on the planting technique and the condition of fertilizer and water. In general, the soil is better to apply organic fertilizer with powder when transplanting, which has fast-acting nitrogen, phosphorus and potassium, and directly takes root and grows leaves after planting seedlings. You can also compare experiments yourself.

Watermelon seeds can generally germinate in two days after planting.

In a suitable environment, watermelon seeds can germinate and emerge after planting generally 36-48 hours, 30 degrees environment is very suitable for watermelon planting, as long as the constant temperature and moisturizing measures are applied vertically, and pay attention to the prevention and control of pests and diseases, watermelons can quickly germinate and emerge seedlings. In addition, the seeds of large watermelon are generally sown and propagated, if the watermelon seeds are not soaked when sown, then germination takes about 30 days, and if the growth environment is not suitable, the germination time may be delayed.

Extended information: Watermelon seed sowing and germination method technology.

1. Dry seeds. Before sowing, choose a sunny day to sow in the sun, and be careful not to sow on the cement floor in summer to avoid burning the seeds. Select the whole seeds, place the seeds in clean water, remove the seeds that float on the surface of the water, and leave the seeds that have sunk to the bottom to sprout.

2. Soak seeds. There are pectin, sugar and other substances on the surface of watermelon seeds, which have the effect of inhibiting germination. The seeds must be rubbed several times in clean water to wash away the debris from the surface of the seeds while reducing bacteria and then allowing them to macerate.

After the soaked seeds are dried, they are spread out in an indoor stand for about 10 minutes to dry, so that the surface of the seeds is slightly dry to improve the air permeability of the seeds.

3. Germination. Wring it out with a towel or cotton cloth so that it does not drip water, and sprinkle the seeds evenly on top. Then roll it up.

In an environment of around 30°, moisturize in plastic bags or other containers and flower buds. Use thermostats, hot water bottles or other insulation measures to maintain a suitable and stable temperature. When two-thirds of the seeds are white, they can be planted.

4. Sowing. Use a 32-hole seedling tray - mix well with substrate - load the hole tray and press a sowing hole of about 1cm. One hole and one grain, the cover substrate is scraped flat - watered thoroughly - covered with mulch film or non-woven fabric - covered with small arch shed - removed from the mulch film - artificial "off the hat".

Watermelon seeds are planted directly in the soil for 5-7 days to germinate.

The germination temperature of the seeds is about 25, the appropriate temperature is about 30, the relative humidity in the air is required to reach more than 80%, and the environment of 30 degrees is very suitable for watermelon planting.

The growth rate of watermelon seedlings is very fast, in the case of sufficient fertilizer and water, 7 days can grow a pot of relatively vigorous small melon seedlings, in the vigorous growth period of watermelon seedlings, you can appropriately increase some rotten organic fertilizer, can make the watermelon vine lack of fiber talk about the growth of the state become better, and after a month, give it more phosphorus and potassium fertilizer, can make watermelon flowers bloom more.

How long to water watermelon after it emerges

1. Under normal circumstances, melon seeds can be watered after 5-7 days (transplanting), in winter and spring, the temperature of the seedbed needs to be kept at about 30 during the day, and the temperature of the seedbed needs to be kept above 20 at night, so that after about 5-7 days the seeds can emerge, and the seedlings should be ready for transplanting after the emergence of seedlings.

2. After transplanting, wrap the watermelon seedlings with straw (or plastic film) to prevent the seedlings from being frozen, and remove the plastic film after the watermelon seedlings begin to stretch (at this time the natural temperature is generally relatively stable), the growth rate of the watermelon seedlings is slow, and the watermelon seedlings should be watered frequently during the period.

The result of watermelon regeneration is to harvest two melons at one time, that is, after the first watermelon is harvested, the vines are cut to leave stubble.

The method of re-germinating melon vines and then forming melons again. This method can increase yield, reduce costs, and increase economic efficiency.

Extend the watermelon market time. Generally, each mu (1 mu 667 square meters, the same below) can be born.

Produce 1000 1500 kg of watermelons in the second crop. Its main cultivation techniques are as follows.

1. Select suitable varieties Choose early-maturing, high-yield, good quality, easy to germinate and regenerate new shoots.

Varieties, including Zhongyu No. 1, Zhejiang honey No. 2 and other varieties.

2 kinds of good stubble melons (1) are sown in a timely manner, and the seedlings are transplanted early in the double shed. In early March, greenhouses are used.

Cover a small greenhouse nutrient bowl to raise seedlings, and transplant the bowl to the melon furrow in the field before and after the Qingming Festival, and use double membrane cultivation.

Technology. Use 80 100 cm of mulch film to til, then make holes and transplant watermelons, and then erect a canopy to cover.

Cover the film. The width of the shed is 1 4 meters, and the height of the shed is to facilitate manual operation. (2) Reasonable dense planting. Acupuncture distance 3

5 cm, 600 holes per mu. (3) Scientific fertilization. To improve the sweetness and yield of watermelon, base fertilizer.

Sufficient organic fertilizer must be applied, generally 75 100 kg of cake fertilizer per mu, or 7 5 tons of chicken manure, 45 ternary compound fertilizer 22 5 25 kg, applied to the bottom of the bowl when transplanting. At 50 melons.

When the vine sets fruit and begins to swell, the fruiting fertilizer is applied too early, and it is easy to run the vine too late.

Watermelon yield and quality. Generally, 7 5 kg of urea or 15 kg of ammonium bicarbonate per mu is used. (4) and.

The time is pressed by the vine. When the melon seedlings grow to about 30 cm, it is necessary to manage the vines in time to press the vines to make the melon vines divide into furrows.

grows on both sides. Generally, only 1 2 side branches are retained for each plant, and the excess side branches should be removed in time. (5) People.

Pollination. When watermelons bloom, if the number of flowers is small, or in bad weather, artificial pollination must be supplemented. Confer.

Powder should be selected with about 12 leaves of female flowers, if only with about 8 leaves of female flowers and their fruits are not large, should be picked.

Except. Each melon vine should keep a good melon, and the watermelon should be ripe in mid to late June, and it should be picked and marketed in time.

Picking should grasp the principle that it does not affect the maturity of the first stubble melon, but also is conducive to timely cutting and regeneration.

3. Cultivate regenerated melons from late June to early July, after the first crop of watermelons is harvested and cut, due to the relatively high temperature.

High, sufficient sunlight, moderate rainfall, 7 to 10 days after cutting the vine can grow into a new vine, and soon flowering and knotting.

fruit, usually 40 to 45 days can be harvested two crops.

I think it depends on whether your local climate can sustain it until it matures. It takes at least two months for watermelons to grow to ripen! If you have a normal climate and the temperature is hot enough, you can ensure the growth of watermelons.

If you can't keep it warm, you won't be able to grow sustainably.

Hello, in a suitable environment, watermelon seeds can germinate and emerge after planting in 36-48h, and the 30-degree environment is very suitable for watermelon planting. In addition, watermelon seeds are generally sown and propagated, if watermelon seeds are sown without soaking the ear and soak the treatment, then germination takes about 30 days, if the growth environment is not suitable, the germination time may be delayed.
