How many days can watermelons be planted to irrigate the roots?

week. How can we ensure that the seedlings are slow after transplanting?

A low ground temperature. The minimum temperature conditions for radicle elongation and lateral root regeneration are 13, and the ground temperature of 18 is usually required for normal roots. Transplanting melon seedlings in early spring often encounters the situation that the ground temperature of 10 cm underground does not reach 15 and cannot germinate.

It should be transplanted after taking methods such as buttoning film and spraying foliar fertilizer in advance to increase ground temperature or take root-promoting methods, and [Bicca Root Congcong + Bacterial Fertilizer] can be used to irrigate roots to increase ground temperature and promote root development.

Second, avoid the use of raw manure and uneven soil mixing in the bottom fertilizer. After watermelon transplanting, the root system will "burn the roots" when the root system comes into contact with unripe organic fertilizer and chemical fertilizer with excessive concentration, which will delay the seedlings or cause the seedlings to die. Therefore, before applying organic fertilizers such as chicken, pig, cow manure, etc., it must be fully decomposed, and the base fertilizer should be fully mixed with the field bed soil.

Three taboos old and young seedlings transplanting. The appropriate age for normal transplanting of watermelon is the four-leaf stage. Because of the small growth of seedlings, the adaptability and resistance to the outside world are poor, and the seedlings are slow. However, the large seedling age of more than five leaves will cause undesirable results such as root injury, corkification of the outer epidermis of the stem in the ground, and hollowing of the pith.

Fourth, avoid lack of water and watering discomfort in the seedbed. Traditional transplanting methods often cause root epidermis to cork and scatter with root nutrient soil, which will seriously damage the roots. After transplanting, the flood irrigation will soften the ground and make the ridge soil compact.

After planting, watering will make the seedling soil and the ridge bed not well connected, and the transplanting seedbed crack and air breathability will also affect the root growth. The accurate method is to control the temperature and water of the seedbed before transplanting to maintain the health and integrity of the root system; After transplanting, under the condition of maintaining the ground temperature, it is necessary to bridge the tight bed soil and guest soil after watering or watering dark water.

Five taboos to ignore soil treatment. Due to the expansion of watermelon production in recent years and the growth of crop biological yields, the stock of pathogens and pests in the soil is also growing. For example, the spores of watermelon blight and anthracnose will occur earlier with the increase of ground temperature.

Neglect of soil pest control can also have serious consequences. To make ridges and furrows, it is necessary to apply drugs such as carbendazim, tobuzin, trichlorfon, and phosphine to disinfect and sterilize the soil to ensure the normal growth of watermelon seedlings after planting.

Sixth, avoid wind discomfort. The cultivation of early-maturing watermelons should adopt methods such as buckle the shed and cover the film to increase temperature and heat preservation. Watermelon seedlings can tolerate high temperatures of 38 and low temperatures of about 10 when they are not in direct contact with the greenhouse film, and beyond this temperature limit will cause roasted seedlings or cold damage.

Seven taboos are premature topdressing and watering. The amount of fertilizer for watermelon seedlings should be determined according to the seedling condition and soil fertility. Watermelon can be sprayed after transplanting [Bika foliar fertilizer], watermelon seedlings should generally be applied after the five-leaf stage, with watering to apply an appropriate amount of nitrogen, phosphorus and potassium, to promote the early growth of watermelon, and too early water and fertilizer supply is harmful.

After the watermelon is planted, it needs to be watered slowly for about 7 days, and the seedling condition and soil moisture should be decided according to the time. Watermelon seedlings should be watered at 8-10 o'clock in the morning on a sunny day, you can dig a shallow ditch on the side of the watermelon seedlings, water in and then cover the soil, so as to promote the seedlings as soon as possible. Watermelon is a common fruit in summer, not only delicious, but also has the effect of relieving heat, so it is a favorite food for many people.

First of all, the root irrigation water should be sufficient, and the roots can be irrigated after about a week.

If you plant it for a few days, you can see the root watermelon, if it is hit, then it will take many days before it can be closed, so this is also a watermelon that has a growth cycle in a few days, and you can irrigate the root watermelon in a few days, if it is medium, then it will take many days before it can be closed, so this is also a growth cycle, not that it can be closed in a few days.

Hello dear <>

We are happy to answer your questions as follows: Should watering watermelon seeds after sowing 1It needs to be soaked in water for about 4 hours, and the soil is watered thoroughly and then sown into it, (watering through the pants does not need to be watered first, observe the ginger for 2 3 days, if the soil is found to be dry, and then water again) Cover the dry soil; 2.

Another sowing method is more complicated, but it can ensure better germination - open a small hole about 2 cm deep in the middle of the soil, put the seeds of the watermelon in, cover it with soil and then water it thoroughly, be careful not to water the position of the seeds when watering, and should be full of water along the perimeter of the pot.

Summary. Watermelons need to be watered after transplanting, generally speaking, transplanting about a week to water the seedlings to keep the soil moist. The details are as follows:

Watermelons need to be watered after transplanting, generally speaking, transplanting about a week to water the seedlings to keep the soil moist. The details are as follows:

Watermelon can be watered after transplanting, but can not be watered immediately, watermelon transplanting about 7-10 days for its slow seedling period, this time period is the period when it takes root faster. After transplanting, in order to increase the surface temperature and humidity and promote the rapid growth of roots of watermelons, we can also use ground planting film to reduce water evaporation.

Is watering watermelon first when transplanting?

Watermelon seedlings are not watered before planting, but once after planting. In fact, this method is harmful to watermelon growth. When the watermelon seedlings are just planted, the seedlings have been transported and planted, and the roots, stems and leaves have been damaged to a certain extent, and the seedlings need to be restored slowly.

If the drought is too high at this time, the root system will be severely damaged, and it will be difficult to recover in a short time after watering, and the growth of the plant will be greatly affected.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: hydroponic watermelons can be moved to the soil in a few days:

Hydroponic watermelons can be moved to the soil for a few days.

When the seedlings grow to 3 or 4 true leaves, they can be planted, and it is advisable to do it in the morning on a sunny day. Watered thoroughly 1 day before planting, and the seedlings with more consistent growth were planted together during planting to facilitate later management, and watermelon seedlings can be transplanted and planted in river sand when they grow to 2-3 true leaves. Cultivated by hydroponics, fertilizer will not be lost through osmosis, which can improve the utilization rate and protect the environment.

Watermelons can emerge after about 5-7 days after sowing. The germination temperature of the seeds is about 25, the germination temperature is about 30, and the air humidity should reach more than 80%. Before sowing, the seeds should be sunned, and then soaked for 4-6 hours after the seeds, during which the pectin and other substances on the surface of the seeds should be washed, and then the seeds should be removed and placed in the greenhouse to germinate, and the seeds will germinate after about 3-4 days.

After the seeds germinate, they can be sown in a nutrient bowl, and after sowing, they should be covered with fine soil and kept at a suitable temperature.

How long after watermelon emerges watering Wu Yujian.

1. After the watermelon seeds emerge, they can be watered after 5-7 days (transplanting).

2. In winter and spring, the temperature of the seedbed should be controlled at about 30 during the day and more than 20 at night, and the seeds can emerge after about 5-7 days at this temperature. After the emergence of seedlings, it is necessary to prepare for transplanting and planting, apply well-rotted farmhouse fertilizer before transplanting, and then water after planting.

3. After transplanting, wrap the watermelon seedlings with straw (or plastic film) to prevent the seedlings from freezing. After the watermelon seedlings begin to stretch out (at this time, the natural temperature is generally relatively stable), remove the plastic film. The growth rate of watermelon seedlings is slow, during which the cavity pants should be watered frequently, and the melon seedlings should not be over-applied with nitrogen fertilizer after the vine is stretched to avoid the growth of the plant.

How to grow watermelons.

1. Soak seeds to promote germination.

When planting watermelon, choose seeds with full grains and no pests and diseases, soak them in water for 4 hours, then take out the seeds, wrap them in a wet towel, put them in a warm environment, and wait for the watermelon seeds to be successfully exposed, and then take them out and sow them.

2. Sowing and planting.

When planting watermelon, dig a soil ditch with a distance of 2 meters in the soil, and then sow the seeds in the ditch in the six method, keep the plant spacing at about 50 cm, and put 2 seeds every six to improve the germination rate of the seeds.

3. Field management.

After the watermelon seedlings emerge, it is necessary to apply a microbial agent to destroy the search once a month to promote the growth of the plant, wait for the melon seedlings to grow to a length of 40 cm, and use bamboo poles and ropes to build a bracket to pull the melon vines to grow upward, and after the watermelon enters the flowering period, it is necessary to carry out artificial pollination to improve the fruit setting rate.

Summary. Generally speaking, it takes about 5-7 days for watermelon seedlings to adapt and take root after they are grafted. Then you can start watering them gradually, but be careful not to water them too much at once, otherwise it is easy to cause root rot.

It is recommended to water once a day at the beginning, and each watering can keep the soil moist. As the plant grows, the watering frequency can also be gradually reduced, adjusted according to the actual situation.

As the plant grows, the frequency of watering can be gradually reduced, and the ridge can be adjusted according to the actual situation.

It is to draw water with a sprayer.

It is recommended to wait at least 7-10 days after the watermelon seedlings are connected to allow them to adapt to the new environment and take root. Then you can gradually start using a sprayer to water the watermelon seedlings, but you need to pay attention to the following things:1

The sprayer should be evenly dispensed with water, and the amount of water should not be too much or too little. 2.The atomized water cannot be sprayed directly on the leaf surface of the melon seedlings, which is easy to cause diseases and pests of dried oranges.

3.It is best to choose the time of spraying water in the morning or evening to avoid too fast evaporation caused by too strong sunlight or too high temperature. 4.

If the weather is dry or hot, you can increase the number of sprays or the amount of watering appropriately. In short, the use of a sprayer to water watermelon seedlings requires perseverance, paying attention to the control of water volume and time, so that watermelon seedlings can grow healthily in a moist environment.
