What happens when the watermelon grows and the vine does not develop?

In the stage of vine extension, under normal circumstances, the growth length of watermelon plants is about 8 cm in a day and night, and it can be called "long" if it exceeds this length, which is mainly manifested as internode growth, petioles and leaf bodies are thin and long, leaf color is light, leaves are thin, and female flowers are delayed; When the female flowers open, the melon stalk is thin and short, and the ovary is also small, which is easy to shrink and turn into melon.

Solution-oriented control of the long term.

1. Control the application of nitrogen fertilizer and water, inhibit the vegetative growth of watermelon plants, and shift the growth center to reproductive growth;

2. At the beginning of the 4-6 nodes of watermelon plants, continuous foliar spraying with boron fertilizer + potassium dihydrogen phosphate 1000 times can also promote the transformation of watermelon plants from vegetative growth to reproductive growth;

3. In terms of management, it is necessary to ventilate and drain moisture in a timely manner, increase the light in the shed, avoid the temperature in the shed being too high in good weather, and adopt large temperature difference management to reduce the night temperature;

4. For plants that have grown up, the nutrient distribution of watermelon plants should be adjusted through pruning, topping and other measures to control the vigorous vegetative growth.

If the watermelon grows slowly and does not develop, it is because it is malnourished, apply compound fertilizer, phosphate fertilizer, nitrogen fertilizer and potassium fertilizer, and then put it in a sunny place.

Are you talking about watermelon? The pain doesn't blossom very much. You may have planted it too late. Or are you not in Dingxin, and you didn't let him branch out? It's too hot now, and if it hasn't grown well, I'm afraid it will be difficult to bloom and bear fruit.

Watermelon lives on vines and the soil is long, and the side vines are not developed.

This is caused by a lack of light.

You can also apply a small amount of fertilizer or use some medicine.

This is a typical sign of a lack of phosphate fertilizer, in which case it is necessary to give him some liquid fertilizer or temporary potassium dihydrochloride.

What's the matter with the main watermelon vine growing and the side vines not developing? This situation is due to insufficient nutrition, watermelon has caused a top advantage, if you want to develop side vines, you need to spray foliar fertilizer, potassium dihydrogen phosphate, or root top dressing, so that the side vines will grow, watermelon can only leave two to three strips, the rest of the side vines should be pinched off.

Watermelon to pinch the main vine, because the growth rate of the main vine of watermelon is fast, will consume too much nutrients of the plant, resulting in poor growth of watermelon, you need to prepare a pair of sterilized sharp scissors to cut the branches of the plant that grow too long, so that its nutrients are concentrated, which is conducive to the growth of watermelon fruits.

Vine stretching fertilizer: watermelon enters the vine extension period, the demand for fertilizer and water increases, at this time, top dressing should be aimed at promoting the growth of vines and expanding the leaf area, but to prevent growth. Top dressing is mainly decomposed water-soluble fertilizer, with an appropriate amount of microbial agent, the effect is very good, and it is very cost-effective.

Bulging melon fertilizer: When the normal watermelon grows to the size of an egg, it begins to expand rapidly, and the fertilizer demand gradually reaches the peak of the whole growth period. At this time, the bulging melon fertilizer should be reapplied to promote the expansion of the melon body and prevent premature aging.

Top dressing is mainly phosphorus and potassium fertilizer, with less or no nitrogen fertilizer to avoid reducing the quality of watermelon due to excessive nitrogen fertilizer. Apply high potassium fertilizer per acre. Apply in the hole 30cm away from the melon root next to the ridge, or between the two plants near the ditch.

After fertilization, water the gourd water in time to promote nutrient absorption and speed up the expansion of watermelon.

Reinvigorating fertilizer: After the first stubble melon is harvested, immediately apply 1 fast-acting chemical fertilizer, generally 15-20kg of urea, 15kg of potassium sulfate, 10kg of diammonium phosphate per mu, and combined with top dressing, watering 1 time. By strengthening management, replenish nutrients and water in the soil, maintain the strong growth of watermelon, and prevent premature aging of vines.

First of all, it is necessary to observe that if it is a greenhouse watermelon, it needs to be done manually because the bees cannot enter the pollination. Watermelon belongs to cross-pollination, flowers can't pollinate, how to produce melons? If it is the same as watermelon in the open air, the solution can be "flower" artificial pollination, if there is no artificial pollination, pollination is the best at this time, and the pollination fruit setting rate after 10 o'clock decreases significantly.

In the natural state, it mostly relies on bees and other insects for pollination; With the development of production, especially the early maturing cultivation in protected areas, artificial assisted pollination should be vigorously advocated to ensure adequate pollination.

The fertilizer ratio is unreasonable, and too much nitrogen-containing fertilizer is applied, resulting in vigorous vegetative growth or even crazy growth. Watermelon needs comprehensive and reasonable nutrition during the growth and development period, and is sensitive to nitrogen fertilizer in a large number of elements. If there is less, the plant will grow slowly and will not be vigorous, but if there is more, it will grow wildly and turn into melons.

Delay and affect the time of the appearance of female flowers, the female flowers on the watermelon seedlings are the key to fruiting, there are no female flowers or the female flowers are too late is not easy to set melons, the melons that appear in the position of high knots and vines in the later stage are not large, and are also prone to deformity, can not form commercial melons for sale.

According to the characteristics of the variety, the special animal requirements should be reasonably densely planted to prevent the reduction of ventilation and light transmittance due to over-dense planting, and the fall of flowers and fruits in case of high temperature weather. Fourth, select excellent varieties with strong resistance to the growth of local climate, increase the fruit setting rate of watermelon, and improve the yield and quality. The more female flowers there are, the greater the chance of natural pollination, and thus more watermelons bear fruit, but only one large watermelon can be left on a watermelon vine.

Then there are external reasons for pollination, that is, there has been more rain recently, there are fewer bees, and natural pollination is much slower.

The temperature is more suitable for the growth of watermelon seedlings, so after purchasing watermelon seedlings, they are directly planted in the garden. At this time, there is no need to consider whether the soil temperature will be too low and affect the growth and development of the root system. Because the watermelon seedlings planted at this time will basically not be covered with mulch.

This is usually related to weather, breed and management methods. First, it is necessary to pay attention to the control of watering and fertilization. Second, it is necessary to clean up the ineffective branches in time, which will compete for nutrition. Third, you can spray the drug to control its growth.

1.The lack of nutrient fertilizer makes the young melon fall off due to physiological disorders, resulting in the stunted development of female flowers; 2.If the variety is not selected, you can appropriately extend the time of sitting melons to avoid this situation; 3.The growing environment is harsh, which is not conducive to the growth of watermelon.

The main reason is that the fertility of the soil is not enough at this stage, so there will be no melons, in which case it is necessary to fertilize the soil a lot.

It may be because you haven't done a scientific approach, so you will only grow vines and not melons, and you need to press the head, so that you can bear fruit.

This is because watermelon usually lacks water, and it lacks nutrients, so it will never bear melon.

Reasons why watermelon vines are not thriving: 1. Pests and diseases. 2. Root rot.

3. Low temperature. 4. Improper management of water and fertilizer. Watermelon vines are weakened as long as the cause is malnutrition.

It is mainly caused by pests and diseases, improper fertilization, too low temperature, and too high humidity. The reasons for the weakening of watermelon vines are: low temperature, pests and diseases, lack of fertilizer and water, etc.

The main reasons for the weakening of watermelon vines are: pests and diseases, fertilizer and water management, excessive rainwater aberration, and soil peel. Affected by weather, nutrients, pests and diseases.

Pests and diseases can cause weakness due to improper management of fertilizer and water. Watermelon seedlings may not be strong or not in time during the growth period, or the application of water and fertilizer is too large, resulting in the growth of watermelon seedlings, you can spray the control agent during the vine extension period, and at the same time when the main vine grows to 50-70 cm and the side vine grows to about 20 cm, select 1-2 strong side vines at the base, and then cut off other side vines.

At this time, don't wait any longer, otherwise even if you sit, it is too far from the root, the nutrients are not high, and the gourd-shaped melon appears, cut off 1-3 from the root, keep only 1 vine, and beat off all the side branches of this vine.

Pinch the tip of this vine, so that this vine no longer has any growth point, and can only photosynthesize and produce nutrients. Leave 2-3 small vines from the root to form melons, if there are no small vines on the roots, there is no growth point after pinching the tip and hitting the branches, and then there is no growth point, and you can build a new vine from the root 2-3 days.

At the same time, top dressing, watering, irrigation and regular spraying of special foliar fertilizer management should be carried out, because the original fertilizer has been consumed. The small vines that come out of the new vines must also be hit in time, about ten days after treatment, you can bear melons, and the new vines that come out of the back can leave the second female flower, when you want to sit on the melons, the old vines that are left will also begin to age, but the jujube beam will be cut off, only the new vines will be retained, and the management is good, and the yield will not be low.

Summary. Hello dear! We'll be happy to answer for you.

The watermelon does not set fruit and the main vine is too long to deal with the following methods: 1Proper fertilization:

When fertilizing, it is necessary to pay attention to controlling the dosage, pay attention to the ratio of chemical fertilizers, and try to use organic fertilizers. Under normal circumstances, the ratio of nitrogen, phosphorus and potassium in each watermelon plant is moderate irrigation: attention should be paid to water control during irrigation, avoid water accumulation in the field, and ensure that the root system is breathable and the water is reasonable**.

3.Adjust the temperature: In the high temperature season, you can use shade netting or watering to cool down and control the growth rate of melon seedlings.

4.Reasonable management: The management of watermelon should take different measures according to different stages.

For example, during the fruit setting of watermelons, the shaking method can be used to promote pollination and allow the pollen to adhere better to the stigma. 5.Pinch Control:

When the length of the melon vine reaches 2-3 meters, the pinch can be controlled to allow the watermelon flowers and fruits to develop better.

Reasonable management: The management of watermelon should take different measures according to different stages. For example, during the fruit setting of watermelon, the shaking method can be used to promote pollination, so that the pollen of the withered brigade can better adhere to the stigma.

5.Pinch control: When the length of the melon vine reaches 2-3 meters, the pinch control can be carried out to make the flowers and fruits of the west side of the god melon develop better.

Dear, you can. Pinch control: When the length of the melon vine reaches 2-3 meters, the pinch control can be carried out to make the watermelon flowers and fruits develop better.

The main vine is too long-looking, and I want to cut the main vine and leave the side vine to set fruit. May I.

Dear, it's okay to start Qiaoxian. But pay attention to the method of sneaking and timing. It is generally recommended to keep 2-3 strong and flame-disabling side vines, and prune and adjust them in time to achieve the best growth and yield results.

Summary. The watermelon vine extension period should be adjusted according to the growth of the vine, and the watermelon seedlings should start to grow when they reach about 40 cm.

How to remedy the short watermelon side vine?

Watermelon vine extension period should be based on the growth of the whole vine, watermelon seedlings grow to about 40 cm when it is necessary to open the beginning of the whole vine, the whole vine should be taken for the weak and strong trees to take different whole vine strategy, to adjust the growth of watermelon.

The melon vine is properly coiled and opened to inhibit the growth of watermelon to a certain extent, and for the plants with weak growth, it is necessary to grind the vine early and trim it lightly, and try to be filial piety not to affect the normal growth of the melon vine.

It can also be adjusted by fertilizer and water, and weak plants can be irrigated with water-soluble fertilizer to promote root growth and improve the growth <> of secondary vines

At the beginning, the length of the secondary vine and the main vine is about the same, so the secondary vine is cut off and the teeth are re-generated, what should I do if the main vine is too short now?

Hello dear, the main thing is that the root system is not well developed, after you cut the vine, watering and fertilizing.

No. The side vine is cut too short, how to remedy.

The root system is well developed, but the pruning is too short.

After cutting, it is necessary to water, fertilize, and slowly grow.

How long does this shear take.

Just cut. That's fine, watering and fertilizing will be fine.

It is best to prune the lateral branches when they grow to 15 cm, and in specific operations, they should be treated flexibly according to the growth of the plant, and the weight should be moderate.

Fertilization was carried out in three phases 7 days before cutting, 2 days after cutting, and 7 days after cutting vines in Jingzhen. The results showed that different bright and coarse fertilization periods had a great impact on the yield of regenerated melon, and fertilization was applied on the 7th day before cutting.

Pay attention to the stubble should not be too long to pretend to be cracked, because the axillary buds of the high node are slow to germinate, and the new vines are thin and weak, while the axillary buds of the round part of the gila germinate quickly, and the new vines that are drawn are stout, easy to sit on the melon, and the large melon hall is closed.
