How to plant watermelon seedlings, how to plant watermelon seedlings

Method steps.

First of all, cover the ridges reserved in the field with a layer of plastic film [plastic film, black, with the effect of weeding; Another function is to give the seeds under the mulch film a constant temperature, so that the seeds can germinate at a faster speed and in a shorter time, and drill out of the surface

On the covered mulch, according to a certain spacing, use a bowl picker to make holes one by one. [The role of the bowl is like the Luoyang shovel in "Notes on Tomb Robbery", the probe is pressed into the soil, and when it is taken out, it takes out the soil it has inserted, leaving a hole. 】

Scoop the watermelon seedlings out of the petri dish with a spoon, place them in the hole made with a bowl picker, and water them with a small kettle. [Do not let the soil cover the center of the seedlings, otherwise the seedlings will stop growing and die].

Cover the roots of watered watermelon seedlings with a thin layer of wet soil to prevent the watered water from being evaporated and dried by the noon sun, which plays a role in preserving moisture.

Here's what you're done**.

1. Sow seeds at the right time. Cultivate stout melon seedlings. The key to cultivating stout seedlings is to sow seeds in a timely manner, and use a new high-fat film to dress seeds (which can be mixed with seed coating agent) before sowing, which can repel underground pests and diseases, isolate virus infection, do not affect the germination and swelling function, strengthen respiratory intensity, and improve seed germination rate.

Take a hotbed agricultural film arch shed for seedlings raising. In the middle and late stages of seedlings, more exposure and less covering, day and night cover, 3-5 days before transplanting, can be unveiled and refined seedlings around the clock, so as to help cultivate healthy and thick melon seedlings.

2. Apply sufficient base fertilizer. Watermelon requires a large amount of fertilizer, therefore, applying enough high-quality base fertilizer is the basis for obtaining high-quality, stable and high-yield watermelon. 1500-2000 kg of rotting fertilizer needs to be applied per mu, and 25-30 kg of compound fertilizer (watermelon special compound fertilizer is better).

The fertilization method can be changed from the previous single furrow fertilization to double furrow fertilization, that is, on both sides of the middle of the compartment surface that are 30-40 cm apart, each open a deep and wide ditch of 20-30 cm, and then apply fertilizer into two furrows, cover the soil about 5 cm, and the melon seedlings are planted in the middle of the two fertilizer ditches. The advantages of this kind of fertilization are: do not burn seedlings, and prevent growth, timely spraying to promote Kao No. 3, can transform plant vegetative growth into reproductive nutrition, inhibit the crazy growth of the main shoot, promote flower bud differentiation, more flowering, improve the quality of pollen fertilization, more flowering, more fruit set, prevent fruit dropping, and promote development.

3. Scientific top dressing. Under the premise of applying plantar fertilizer, only 200 kg of human feces and urine need to be applied once during the vine extension period, and 3 kg of urea is added. Because the watermelon is very sensitive to water and fertilizer during the flowering and fruit-setting period, if the fertilizer and water are excessive at this time, the plant will have excess nutrition, which is easy to cause overgrowth, which is an obstacle to the melon.

Therefore, when the young fruit is as big as an egg, it can be topdressed appropriately, combined with the spraying of strong guati to thicken the guadi, strengthen the amount of nutrient directional delivery, promote the rapid development of the melon body, and the melon shape is beautiful and delicious; The growth cycle does not drop flowers, does not fall melons, does not crack melons, and does not deform melons. When the watermelon swells, the root system just extends to the two fertilization furrows, and the nutrients are sufficient, which is conducive to rapid growth into a large melon with a standard melon shape.

4. Pest control. Cataplexy, blight, and anthracnose are the three main diseases of watermelon. To prevent and control cataplexy at the seedling stage, pay attention to ventilation and control watering in the seedbed.

Fusarium wilt and anthracnose prevention and control methods: avoid continuous cropping, generally interval of 4-5 years, do a good job of ditch cleaning and drainage, and find that the diseased plants are uprooted in time. Pharmaceutical prevention and control:

Spraying with 75% chlorothalonil wettable powder, or 70% dixone, or 20% sparkling, or Bordeaux liquid, the control effect is very good. Watermelon insect pests mainly include: yellow gourd, ground tiger, aphid and red spider at the seedling stage.

The pesticide control method is to use dichlorvos, dimethoate, trichlorfon and carbofuran respectively, and the effect is better.

Choose loose and fertile sandy loam soil and plant watermelon seedlings in the soil. 3. Seedling stage control: postpone fertilization at the seedling stage, and apply phosphorus and potassium fertilizer 2-3 times at the flowering stage.

4. Precautions: control the temperature in the greenhouse at about 32 degrees Celsius.

1. Planting time

Watermelon has different planting time according to its varieties, the variety is divided into early, medium, late ripening three, early-ripening watermelon can be planted in March, and medium-ripening watermelon can not be planted until about 4-6 months, late-ripening watermelon should be planted in July, different varieties of watermelon planting time can not be confused.

2. Soil planting

Watermelon is suitable for growth and development in sandy soil, its root system is not very deep, but because of the huge fruit it bears during the fruiting period, it needs to transport and absorb a lot of water and nutrients, so it is best to use relatively fertile sandy soil to cultivate watermelon, the unique specific heat capacity of sandy soil is also helpful for the sweetness of the fruit.

3. Seedling stage control

When watermelon grows and develops in the seedling stage, the nutrients required are not much, generally the base fertilizer in the soil is the main one, but when it grows to the flowering and fruiting stage, the nutrients and water consumed will rise to dozens of times, and it is necessary to replenish water and fertilizer in time, and water enough thin fertilizer to be applied frequently.

4. Precautions

Watermelon is a plant that likes to live in a warmer environment, the tolerance to cold gives poor yield, the seeds can germinate in an environment above 15 degrees Celsius, the most suitable ambient temperature during the growth period is about 32 degrees Celsius, but the temperature difference between day and night should be 10 degrees Celsius, and the temperature at night is best around 20 degrees Celsius.

Watermelon seedling planting method: planting time, processing seeds, sowing seedlings and talking about stupid birds, timely planting, and later management.

1. Planting time

Watermelons are usually grown in the spring, depending on the region and the variety being cultivated. If it is an early-maturing watermelon, it is recommended to choose around March every spring, and it will ripen in June and July. If it is a medium-ripe watermelon, you can choose to plant it from April to June.

If it is a late-ripening watermelon, it should be planted around July. If it is planted in a greenhouse, it can be well controlled and can be planted at any time.

2. Treat the seeds

Watermelon seeds should be germinated in advance before sowing, choose full watermelon seeds, soak them in warm water at 55 for about 12 hours, so that the skin of the seeds will become soft, which can promote germination as soon as possible. After soaking, put it on wet wipes to promote germination, and spray water every day during germination to ensure high humidity, so that the seeds will germinate soon.

3. Sowing seeds and raising seedlings

After germination, the watermelon seeds can be planted in the soil. Water thoroughly first, then sow the watermelon seeds into the soil, cover the thin soil, and provide a warm environment, so that watermelon seedlings will soon grow. If the temperature in the area is low, it must be covered with plastic film after sowing to keep warm and moisturize, and the environment is suitable to promote the growth of seedlings as soon as possible.

Fourth, timely planting

When the watermelon seedlings grow to 10-15 cm long, they can be planted. When planting, first use a hole punch to make a hole with a depth of 5 cm and a diameter of 4 cm in the mulch, and then plant according to the plant spacing of 30-35 cm containing early rice, and water it thoroughly in time after planting, and it will soon resume growth.

5. Post-management

Watermelon seedlings consume more nutrients during the growth period, in order to promote its better growth, it is necessary to regularly top dressing to ensure sufficient nutrition. In addition, greenhouse cultivation needs to be pollinated in time and thinned to ensure the amount of fruit and fruit.

<> choose to plant watermelons in sandy soil with deep soil layer, loose and fertile soil, and trim the field before sowing and apply sufficient base fertilizer. Water the melon field thoroughly in the afternoon of the day before sowing, choose a suitable time for planting, and plant at a reasonable density. Try to water less or no watering at the seedling stage of watermelon, which is conducive to the formation of a developed root system, and do not prune on rainy days to avoid infection.

Before watermelon flowers and fruit set, the amount of watering should be controlled to avoid excessive growth.

1. How to grow watermelons

1. Choose to plant watermelons in sandy soil with deep soil layer, loose and fertile soil, and good drainage performance. Before sowing, the field should be trimmed and sufficient basal fertilizer should be applied, generally organic fertilizer and cake fertilizer are the mainstay, supplemented by inorganic fertilizer. Then dig the box ditch, waist ditch, and surrounding ditch to improve the drainage and irrigation system of the field.

2. Water the melon field thoroughly in the afternoon of the day before sowing, and the sowing density should be reasonable. Watermelon is divided into early, medium, and late-ripening, generally early-ripening watermelons can be sown around March, medium-ripening watermelons can be sown in April-June, and late-ripening watermelons can generally be sown and cultivated around July.

3. The water requirement is relatively low in the watermelon seedling stage, and the seedlings should be watered as little or no as possible during this period, so that the seedlings can form a developed root system. Do not prune on rainy days to avoid infection. When the vine grows to about 50 cm, you can press the vine with soil, every 3-4 knots, and each vine can be pressed 2-3 times.

4. Control the amount of watering before watermelon flowering and fruit setting to avoid crazy growth. After fruit set, it is necessary to ensure sufficient water**, which will help the fruit to expand and increase the weight of the fruit. When the young melon grows to the size of an egg, it can be applied in time according to the growth of the plant.

Second, how to raise watermelon seedlings

1. Watermelon seedling varieties are generally selected with short growth period, disease resistance, strong growth potential, high melon sitting rate, storage and transportation, etc., watermelon seedling nutrient soil preparation generally selects well-rotted farmhouse fertilizer and field soil, and then stirs the soil evenly and dries it in the sun, and then screens it once with a sieve, sprays the water evenly on the nutrient soil, fully mixes it after spraying, covers the nutrient soil with plastic film for 3 days, and then loads the prepared nutrient soil into the purchased nutrient bowl for later use.

2. Before sowing watermelon seedlings, spread the seeds on clean paper and dry them for 4 hours, and then soak them in warm boiled water of about 60, you can stir while filling water, soak them for 4 hours when the water temperature drops below 30, and then take out the seeds and drain the water for germination.

3. Sow the watermelon seeds that promote the germination in the nutrient bowl filled with nutrient soil, and neatly arrange them in the dug seedbed, and each nutrient bowl can be 1-2 grains. Then build a small arch shed and buckle the film, cover the nutrient bowl with plastic film to keep warm, remove the plastic film after the seeds emerge, and the grafted watermelon seedlings are still placed in the small arch shed.

4. Watermelon seeds should be properly ventilated after emergence, when the seedlings grow to 5-6 cm, seedling refining work needs to be carried out, at this time, ventilation should be carried out at night, and the seedling refining should be carried out with a nutrient bowl for temporary maintenance work, and the appropriate time can be selected for planting.

1. Soil: When raising watermelon seedlings, choose loose and breathable soil with good drainage conditions. 2. Germination:

The watermelon seeds are soaked in clean water to absorb water, then wrapped in a damp cloth and placed in an environment of 25 degrees Celsius for germination. 3. Sowing: After the seeds emerge, use tweezers to pick up and plant.

4. Management: ventilate frequently, so that the sprouts can breathe fresh air.

1. Prepare the soil

When raising watermelon seedlings, it is necessary to choose soil with rich organic matter content and good drainage conditions, and can use vegetable garden soil, mud and sandy soil and well-rotted organic fertilizer to provide a loose growth environment for watermelon seeds.

2. Carry out germination

Before raising watermelon seedlings, you need to soak the seeds in clean water, then take them out and drain them, wrap them in a damp cloth, and finally put the seeds in an environment above 25 degrees Celsius for germination, and wait for the watermelon seeds to germinate before planting.

3. Sowing method

Because the watermelon seedlings are very small, the bottom of the seeds should be pinched with tweezers when planting, and then planted into the soil, pay attention to control the strength to avoid damage to the watermelon sprouts and stunted growth.

4. Seedling management

After the emergence of watermelon seedlings, it is necessary to ensure the air circulation of the maintenance environment, so that the sprouts can be better breathable, and gradually increase the light intensity, so that the watermelon seedlings can fully photosynthesize and improve the growth rate.
