I planted a lot of cucumbers, but they don t grow, what s the problem?

First of all, in the early stage of cucumber growth, regardless of the growth of the tree, it is dipped in the flower and dipped in the flower. When the cucumbers first started to go on the market, the vegetable farmers felt that the weather was better at that time, so they did not pay attention to the growth of the cucumber trees.

Secondly, the cucumber did not grow well in the early stage. Vegetable farmers said that after planting cucumbers this year, the temperature is relatively high, coupled with the mulching earlier, the ground temperature is high, and the plants are vigorous.

Thirdly, the ground temperature drops after winter, and the root system is not well protected. Technicians dug up a few weak trees in the vegetable greenhouses of vegetable farmers, and found that although the root system of the plants was not diseased, the number of capillary roots was small. This is mainly caused by the fact that the ground temperature drops after winter and the root system is not well protected.

Vegetable farmers believe that cucumbers require fertilizer and water, and the amount of watering in winter is large, which makes it difficult for the root system to recover.

So, in the case of cucumbers in the greenhouse, how to promote its recovery as soon as possible? It is recommended to start with the following aspects for adjustment.

The first is to remove the leading young melons and flower buds in time, and keep the melons reasonably. First of all, all the young melons and flower buds that can be seen on the plant should be removed immediately, reduce the burden on the plant, leave as little melon as possible, remove part of the melon strips on the plant, promote the accumulation of nutrients on the plant, first raise the cucumber vines, and then keep the melon.

The second is to strengthen the management of water and fertilizer and pay attention to root nourishment. In the deep winter, the ground temperature is low, and the root system is already weak, and the root system becomes weaker because there are more melons. Vegetable farmers can apply fertilizer for root protection with water.

If microbial agents, chitin, seaweed extract, etc. When applying the above fertilizers, it is best to use fully water-soluble fertilizers, which not only achieve the purpose of root nourishment, but also provide the nutrients required by the crops.

The third is to spray full-nutrient foliar fertilizer on the foliar surface to raise leaves. Because there were more melons left some time ago, the nutrients made by the plant gave priority to the growth of ** melon strips, and the leaves received less nutrients, resulting in small and yellow leaves. During this time, full nutrient foliar fertilizer should be sprayed in time to promote leaf growth.

When the leaves are raised, more nutrients can be produced, and the root system and melon strips can grow. In addition, attention should also be paid to the prevention and control of leaf diseases, such as downy mildew, bacterial diseases, etc. Downy mildew can be used with enoylmorpholine, gold thunder, etc.; Bacterial diseases can be prevented and controlled by Chunlei King copper, quinoline copper, Chunleimycin, etc., and the effect is better.

Planted cucumbers bear a lot, but they don't grow big, it may be that the fertility is not enough, at this time, you can give him some fertilizer appropriately, and then you can also give him some drugs to help him grow, so as to promote him to find things better.

Maybe the cucumbers are too much, so they don't grow because the number is a little too dense.

I think you may water less, or the fact that you don't apply enough fertilizer, then you can do some uh points, so well, the cucumbers will grow bigger.

The cucumbers I planted bear a lot, but what is the reason why they don't grow, because there are too many of his family, too dense, and the nutrients can't be supplied, so he grows small, and he should pick some appropriately to let him grow.

I think this should be the problem of its variety, this should be a variety that does not grow, because this is how fruit cucumbers grow.

The cucumbers you pick, they bear a lot, but they don't grow, that's the reason, it's because he has too many of them, he can't grow big, and when he sits and twists, you should unload it, and a few cucumbers can grow?

The cucumbers planted bear a lot of cucumbers, but they don't grow well, which should be a nutrient problem of the land. It can enhance the nutrition of the land.

Sometimes it takes a certain amount of skill to grow vegetables, and you must have enough sunlight, moisture and air.

There are a lot of cucumbers in the field, but they don't grow much, which should be caused by insufficient nutrients or water in the soil.

Hello, this situation should have an effect on the light and rain during the development period of cucumbers, and generally cucumbers need light and rain when they are fruiting.

It has to do with the variety of cucumbers you pick, and if the soil and fertilizer are sufficient, the melons and fruits will grow very well, of course, and yours.

There are a lot of Brother Wang's family, but they just don't grow up, so surely you usually have some fat? It needs to be fertilized more, and it will grow slowly.

In this case, it should be a lack of fertilizer, pay attention to adding some all elements when watering, compound fertilizer is better, is it a good root?

First, there is a lack of fertilizer, and second, the sunlight is not enough to meet the conditions for growth.

This may be a problem with the variety, or it may be a lack of fertilizer.

That may be a matter of variety, some cucumbers are small.

Cucumbers turn yellow and do not grow much after fruiting, and the following methods are required:

1. Increase fertilization: apply rotten organic fertilizer to cucumbers every 7-10 days. Cucumber likes fertilizer, not tolerant of fertilizer, but long-term non-fertilization will lead to its lack of nutrition, so that the fruit wilts, grow is not large, during the growth of cucumber need to apply a rotten organic fertilizer every 7-10 days, appropriate auxiliary foliar fertilizer, to promote the growth of cucumber.

2. Watering in time: Once the soil is found to be dry, it needs to be watered and moisturized in time. Cucumbers like a warm and moist growing environment, if the amount of watering is too little, it will cause the fruit to lack water and turn yellow, and the plant grows slowly, in the process of planting cucumbers, once the soil is found to be dry, it can be watered and moisturized if needed, and it can also spray water to the leaves and air to increase humidity.

3. Infected diseases: cut off the infected branches, leaves and fruits in time, and spray chlorothalonil for disinfection. Cucumber is susceptible to disease infection during the growth period, which will also cause the fruit to turn yellow and grow small, so it is necessary to cut off the infected branches and leaves and fruits in time, and in order to avoid the continued spread of residual bacteria, it is necessary to spray chlorothalonil solution on the wound for sterilization and sterilization.

The reason for the high probability is that the fertilizer is insufficient, the cucumber grows quickly, and the seedlings grow while receiving the melon, which consumes more fertilizer and causes the middle and late flowering to not receive the melon. Or the soil is dry and water-deficient, cucumber consumes a lot of water in a lifetime, dropper cultivation is about 200 square meters per mu, the number of leaves increases in the middle and late stages, the water consumption of transpiration is large, and the lack of soil water causes melon root diseases and pests will also cause melon. It is very simple to grow cucumbers that can continue to bear fruit on the balcony, cucumbers are a kind of climbing vine melon fruits, suitable for raising in the yard to set up brackets, raising them on the balcony can allow it to climb on the fence, set up some small brackets for it, and it can continue to bloom and bear fruit.

Some friends will encounter only flowering and not bearing fruit, the common reason is because the male flowers that have just grown out, and then the female flowers will grow, the male flowers will not bear fruit, they are only as pollinating flowers, and the stalk of the female flowers will have a small melon, which is very different from the male flowers. The reason for the high probability is that the fertilizer is insufficient, the cucumber grows quickly, and the seedlings grow while receiving the melon, which consumes more fertilizer and causes the middle and late flowering to not receive the melon. Or the soil is dry and water-deficient, cucumber consumes a lot of water in a lifetime, dropper cultivation is about 200 square meters per mu, the number of leaves increases in the middle and late stages, the water consumption of transpiration is large, and the lack of soil water causes melon root diseases and pests will also cause melon.

There are many reasons why cucumbers do not grow well after fruiting, and the lack of nutrition is only one aspect, mainly related to the environment and daily management. For example, planted on the balcony, there is less light, photosynthesis declines, the photosynthetic substances produced can not grow cucumbers, continuous low temperature and rainy weather, such problems often occur in greenhouses.

There is another reason, now into the summer, whether it is greenhouse or open field planting, the temperature generally rises, although cucumber is a temperature-loving vegetable, but in the flowering and fruiting period, once the temperature exceeds 35, pollination will be affected, melon strips will not grow large will fall, and the yield will be reduced. In addition, when the variety has a strong ability to produce melons, some farmers keep a lot of melons, some are one leaf and one melon, and some are more than one leaf melon, and the nutrients are easy to not go.

Cucumber melon strips are not big, on the one hand, the temperature should be regulated, the temperature will be higher in the summer planted in the greenhouse, which is not conducive to the growth of cucumbers, try to find a way to reduce the temperature, you can build a shade net, you can also spray a cooling agent on the greenhouse film, without affecting the use of the greenhouse film, reduce the temperature, which method is cheaper, farmers can calculate it according to the local situation.

On the other hand, it is necessary to strengthen daily management, especially after entering the summer, it can be supplemented with nutrients through foliar spraying, which is conducive to the absorption of leaves. Farmers can use sugar plus potassium dihydrogen phosphate, sugar can use brown sugar or glucose, a bucket of water does not exceed 100 grams, potassium dihydrogen phosphate 50 grams, the amount of sugar should not be too much, because insects prefer sweet, so as not to attract insects. When topdressing roots, apply less nitrogen fertilizer and more potassium fertilizer.

When spraying, it is best to spray after four o'clock in the afternoon, avoid the high temperature time at noon, if the temperature is high, it is not conducive to foliar absorption, sugar and potassium dihydrogen phosphate are sprayed before fruiting, and melons can be sprayed after fruiting. After the cucumber is ripe, it should be picked in time to avoid too much nutrient consumption in the lower part and the melon in the upper part of the plant cannot absorb nutrients.

It may be that the nutrients are insufficient, resulting in the stunted development of cucumber fruits, you can try to apply water-soluble fertilizer of trace elements in seedlings to supplement the boron, zinc, silicon, copper and other elements required for the growth of cucumber fruits, improve the fruit setting rate and promote the growth of cucumber fruits, promote early maturity, and increase yield.

There are many reasons why cucumbers do not grow well, such as seeds, light, fertilization management, etc.

Especially in summer, the temperature is relatively high, although cucumber is a temperature-loving vegetable, but in the flowering and fruiting period, once the temperature exceeds 35, pollination will be affected, melon strips will not grow large will fall, and the yield will be reduced.

Secondly, the sparse flowers and fruits must keep up. Don't think that spending more will result more. This is not true. The growth of cucumbers requires sufficient nutrients, and leaving more melons will cause the nutrients to not keep up, and your own cucumbers will not grow big.

The first is that water and fertilizer are in short supply, and some that have not bloomed should be removed.

There is hope for the gherkins.

The second is that it's not already a result.

After flowering, pollination is successful, and the fruit grows day by day, which is the real fruit, you should pick the flowers [male flowers] without cuchkins in the morning, and apply the pollen to the flower columns [female flowers] with cucumbers, and pollinate them manually.

is the cause of nutritional mismatch. Malnutrition will cause deformed flowers, deformed melons, and serious flower and fruit drops.

It may be that there is not enough fertilizer and water.

Cucumber cultivation techniques.

Site preparation. 5 cubic meters of organic fertilizer for land preparation and fertilization, 25 to 30 kg of superphosphate or 10 to 15 kg of diammonium phosphate (5 kg of superphosphate per cubic meter, 2 to 3 kg of diammonium phosphate per cubic meter). Before planting, plough the furrow, the width of the furrow is more than 15 cm, and it is covered with mulch.

Colonization. Determination of planting period: planting as soon as possible on the premise of ensuring that there is no freezing after planting, and planting in Chengde area is generally in late April and early May.

Temperature index requirements: the minimum night temperature is higher than 5, and the soil temperature is higher than 12 at 0 to 10 cm. The cucumber in the autumn dew field adopts the method of live broadcasting.

Planting density: 4000 to 4500 acres, planting in large and small rows, small row spacing 40 cm, large row spacing 80 cm, plant spacing 25 to 30 cm, planting with dark water method.

Manage. Sockets. After planting, the shelf should be planted as soon as possible, and the seedling should be pumped by wind, and the shelf can be a flower stand or a herringbone frame, about 8 to 10 cm away from the root.

Tie vines. The "8" method is used to tie vines to prevent abrasion of stems and vines and sagging stems. Every 2 to 3 knots are tied, should be carried out in the afternoon, the stem vine is easy to break in the morning, the tightness of the vine should be suppressed and the weak should be strengthened, and the growth of the plant should be tied a little tighter, and the height of the growth point is consistent.

Pruning and pinching. For the main vine, all the side branches should be removed, and one or two leaves should be left after the side vine is fruitful, and all the tendrils should be removed. When the stem exceeds the head of the shelf, it is necessary to pinch the tip in time to promote the growth of the lower melon, and the method of twisting the tip can also be used to inhibit the growth of the upper part.

Fertilizer and water management. Timely watering and cultivating, the amount and frequency of water depends on the weather and growing period. Slow seedling water is watered 5 to 7 days after planting; water control, cultivating, and squatting seedlings before sitting on melons; When the root melon is 10 to 12 cm long, water the melon; Watering during the fruiting period is done every 5 to 7 days.

The principle of top dressing is that the front is light and heavy, a small amount of many times, urging melon fertilizer to be applied after the root melon sits, and the melon fertilizer is carried out after the root melon is harvested. Promote the use of organic fertilizer topdressing.

In daily life, you know that cucumbers wilt when they don't grow big, what are the reasons for this? Cucumber is a kind of thermophilic crop, continuous low temperature rainy days, if no measures are taken, can not reach the temperature of cucumber growth, small leaves, poor growth, less photosynthetic substances, can not meet the nutrients required for cucumber growth, will cause melon. In addition to the temperature, after walking around the greenhouse, I saw that Lao Zhang only paid attention to the yield, this variety has a strong ability to produce melons, and there are more melons in one section, but the plant growth is poor, the fertilizer and water are not on the top, and there are very empty orange Qingduo deformed melons have not been removed, which will also affect the growth of normal melons.

Cucumbers will stop growing if they don't get enough nutrients during the growth process, and there are many original bucket grip factors for cucumbers, but the first one is temperature. The normal temperature of cucumber growth is 25 30 during the day and 13 18 at night.
