What are the reasons for the growth of cucumbers and bitter melons?

Cucumbers produce bitter taste, first of all, there is a certain relationship with the variety, and improper cultivation measures will aggravate the appearance of bitter melons:1Excessive application of nitrogen fertilizer Due to excessive nitrogen fertilizer, the plant grows long, and when the melon is not neat, the melon that bears on the side branches and weak branches is prone to bitterness.

2.Slow growth of melon strips During the period of low temperature and low illumination, especially on continuous cloudy days, when the root system or activity of cucumbers is damaged and hindered, the absorption of water and nutrients is less, and the growth of melon strips is slow, and more bitters will often accumulate in the root system and the lower melon. 3.

Bitter melon caused by high temperature Cucumbers cultivated in winter stubble and winter and spring stubble enter the high temperature period in late spring, or due to the senescence of the root system of the plant, or due to excessive soil moisture, the root absorption capacity is weakened, and the assimilation force is weak, and the night temperature is too high, the growth of melon strips is slow, and more bitter pigments are accumulated in the melon strips, thus forming bitter melons. Measures to solve the bitter taste of cucumbers:1

Cucumbers are planted in greenhouses with good lighting and thermal insulation performance. 2.Scientific fertilization, especially do not overapply nitrogen fertilizer.

3.The cultivation density should not be too high, and the light conditions between the plants should be improved. 4.

When the plant enters senescence, it is necessary to rejuvenate as soon as possible by cooling, water control and the application of hormones that promote root development. Entering the high temperature period, the management temperature should not be high, especially to prevent the night temperature from being too high, and the watering should not be too large. Once the bitter taste of the melon is found, the cucumber can be picked and soaked in water overnight, which can also reduce the bitterness of the melon.

The bitter taste of cucumbers is caused by a substance called cucurbitacin (bittersin), which is not only found in the plant but also in the fruit. The content of different parts of the same fruit is different, and the bitterness of the part near the fruit peduncle is generally strong, while the bitterness of the top part of the fruit is light or non-bitter. Cucumber varieties, growing conditions, plant nutritional status, and vitality all affect the occurrence of cucumber bitterness.

The formation and accumulation of picrin can be induced under conditions such as excessive or insufficient nitrogen in the soil, lack of organic fertilizer, low or high temperature, insufficient sunlight, malnutrition, soil drought and water shortage, pests and diseases, and plant weakness. Therefore, in cultivation, we should try to make the vegetative growth and reproductive growth of cucumber, and the growth of aboveground and underground parts be balanced, so as to prevent the occurrence of cucumber bitterness.

What causes bitterness in cucumbers? What is the reason for the formation of cucumber bitter melon? Let's learn.

Tell you the reason for the formation of cucumber bitter melon! Cucumbers sometimes have a bitter taste because melons contain a bitter substance called bitter melon. In general, this bitter section pants ruler flavor has the genetic characteristics of the variety, so whether the refreshing melon flavor is focused or not varies from variety to variety.

According to the occurrence of bitterness, cucumbers can be divided into 3 categories: one is that the vegetative organs have a bitter taste, and the fruit may become bitter; The second type is that the vegetative organs have a bitter and pure taste, the fruit is not bitter, and the environment is not affected; The third category is that the plant and fruit have no bitter taste and are not affected by environmental conditions. At present, many cucumber varieties belong to the first category, so the ecological conditions, the nutritional status of the plant, and the strength of the growth capacity can all affect the production of bitterness.

Therefore, the same plant, the content of bitter in the roots is larger, before and after planting, due to excessive water control, large concentration of cell fluid, and the relative content of bitter melon is high, so it will be bitter. If the water is properly controlled in the future, the growth is fast, and the metabolism rate is poor, the relative content of bitter melonin will decrease, and the bitter taste will disappear. In addition, if the water is properly controlled in the future, the growth rate is slow, and the growth rate is rapid, then the relative content of bitter melonin will decrease.

In addition, too much nitrogen, too much growth, too high temperature, insufficient sunlight, lack of fertilizer, and unfavorable growth of plants will also lead to the senescence of plants. In cultivation, it is necessary to often obtain a balance between plant growth and reproductive growth, and a balance between aboveground growth and underground growth, so that plants can maintain a certain degree of development. Method 1 to remove cucumber flavor

Wash the cucumber and cut a centimeter-long section on the top of the melon (this section is very important, the key to our removal of bitterness is this section)2Close the cut section with the cucumber and gently rub it to remove the bitterness of the cucumber by about a minute of bright red size. Let us share how to cut cucumbers.

Start by removing the head and tail (I'm sure you've already removed the bitterness with what I call stir-frying when removing the guati. Cut in half along the midline, section down, place a portion of the cucumber parallel to the shoulder junction, place it on a cutting board, hold it down with your hand, and cut the cucumber slice at a 45-degree angle with the kitchen knife connected to the shoulder. The cucumber slices that come out of this way will look great and make people appetize.

2.Growing environment.

The bitter taste of cucumbers is mainly due to the cucumber bitters in them. Cucumber bitter is a natural bitter substance, and its content is affected by the growth environment and variety of cucumber. To reduce the bitterness of cucumbers, varieties with no bitterness or less bitterness can be selected, as well as some measures can be taken in post-processing.

The key is exacerbated. The environment in which cucumber is grown can also affect how bitter it is. If cucumbers are grown in an environment that lacks water and nutrients, they will produce more cucumber bitters. In addition, if cucumbers are grown in an environment where the temperature is too high or too low, the content of cucumber bitter will also increase.

3.Post-processing.

The post-processing of cucumbers can also affect how bitter it is. If the cucumber is exposed to the air after the cucumber is cut, the bitterness will be more pronounced. Therefore, it is best to soak cucumbers in salted water before cutting them, or apply some salt to the holes in the incision to reduce the bitterness.

Variety reason: There are many varieties of cucumbers, wild cucumbers contain more bitters, and the products of this kind of cucumber and normal cucumber are bitter. Malnutrition:

Cucumbers have relatively high nutrient requirements during the growth period, poor soil quality, and suddenly too barren, which will lead to an increase in the amount of bitters in cucumbers. Large temperature difference: If the temperature difference is large, cucumbers will accumulate bitters, and the bitter content of cucumbers will be too high, and bitter cucumbers will appear.

Variety reason: There are many varieties of cucumbers, wild cucumbers contain more bitters, and the products of this kind of cucumber and normal cucumber are bitter. Malnutrition:

Large temperature difference: If the temperature difference is large, cucumbers will accumulate bitters, and the bitter content of cucumbers will be too high, and bitter cucumbers will appear.

1. There are many varieties of cucumbers, and there are still many wild cucumber varieties of wild cucumbers, wild cucumbers contain more bitters, and this kind of cucumber is hybridized with normal cucumbers, and its products are bitter, which is related to hereditary, and belongs to different varieties.

2. Malnourished cucumbers have relatively high requirements for nutrients during the growth period, poor soil quality, and suddenly too barren, which will lead to a great increase in the amount of bitters in cucumbers, and it is bitter when eaten.

3. The temperature difference is large and the fruit will gather sugar due to the large temperature difference, and the same is true for cucumbers, but the cucumbers are not gathered with sugar, but bitters, which can lead to too large temperature difference due to the strong resistance of sunlight when planting in greenhouses, and the bitter content of cucumbers is too high, and bitter cucumbers appear.

There are several reasons why cucumbers are bitter: variety, temperature, humidity, malnutrition, and lack of sunlight.

1. Temperature reasons.

When the air temperature or ground temperature is lower than 13°C, the cell permeability in cucumber plants will be reduced, and the absorption of nutrients and water will be inhibited, so it is easy to cause cucumber to appear bitter. At the same time, if the temperature in the greenhouse is continuously higher than 30°C, it will also cause the cucumber to become bitter after a period of time.

2. Humidity reasons.

The humidity in the planting environment is too high, so it will cause some cucumbers to have a bitter taste, so it is necessary to control the humidity in the planting field and do a good job of drainage in the rainy season.

3. Variety reasons.

Some cucumber varieties are prone to mutations during the growth process, and most of the fruits produced by the variants have a bitter taste. Or the variety itself contains more bitters, such as wild cucumbers, when wild cucumbers are crossed with normal cucumbers, their products will generally cover the land with a bitter taste.

4. Malnutrition.

Cucumbers need to absorb more nutrients during the growth period, and if the soil quality in the planting area is poor, or the soil is too poor, the cucumbers will have more bitters, so they will be bitter when eaten.

5. Lack of sunlight.

The cucumber is generally green in color after entering the edible period, at this time it needs to be exposed to sufficient light, if the light duration or intensity is not enough, it will increase the bitter content in the fruit.

The reasons why cucumbers are bitter are as follows:

1. When the air temperature or ground temperature is lower than 13 degrees Celsius, the cell permeability is reduced, the absorption of nutrients and water is inhibited, and the cucumber is prone to bitterness: the greenhouse temperature is higher than 30 degrees Celsius for too long and the duration will also cause the cucumber to be bitter.

2. Cucumbers grown in an environment with excessive humidity may taste bitter.

3. Due to the variety, cucumber plants are prone to mutations during the growth process, and most of the cucumbers produced by bitter variants are bitter.

Cucumber growth distribution:

1. Temperature. Cucumbers prefer warmth and are not tolerant of cold. The fertility temperature is 10 32.

Generally, 25 32 during the day and 15 18 at night grow best; The most suitable ground temperature is 20 25, and the lowest is about 15. The optimal temperature difference between day and night is 10 15. Cucumber high temperature 35 poor photosynthesis, 45 high temperature obstacles, low temperature -2 0 freeze to death.

2. Illumination. South China varieties are more sensitive to short days, while North China varieties are not strict about the length of sunshine, and have become sunshine neutral plants, with a light saturation point of 10,000 lux and a light compensation point of 1500 lux, and most varieties grow well under the condition of 8 11 hours of short sunshine.

3. Moisture. Cucumbers have a high yield and a large water requirement. The suitable soil moisture is 60 90%, the water at the seedling stage should not be too much, the soil moisture is 60 70%, and sufficient water must be supplied at the fruiting stage, and the soil moisture is 80 90%.

The suitable air relative humidity of cucumber is 60 90%, and excessive air relative humidity is easy to get sick and cause yield reduction.

4. Soil. Cucumbers like moisture but not waterlogging, fertilizer but not fertilizer, and it is advisable to choose fertile soil rich in organic matter. Generally prefer soil between pH, but pH is the best.

Because there is no auxin, I think I can choose to water more water to promote the growth of cucumbers, and in addition, to shine the sun.

It may be caused by insufficient light, or it may be due to the improper use of fertilizer during the growth process, and sometimes excessive use of one fertilizer can lead to such a result. Be sure to pay attention to the density of planting, socks should not affect the light, and also disturb the reasonable use of organic fertilizer.

It is caused by the original file of the variety, which may be related to the light and the use of fertilizer, so it is necessary to choose the right variety for planting, pay attention to the density of planting, and pay attention to the light.

An indispensable type of agricultural product. However, many vegetable growers and consumers often report that the cucumbers they grow or buy back from the vegetable market taste bitter, which greatly affects the taste of eating.

So, why do cucumbers have a bitter taste? What causes bitter cucumbers? Cucurbitacin is bitter when the cucumber plant grows and the cucumber strips are still high and immature, and the cucurbitacin is not fully converted.

However, the full transformation of this cucurbitacin is related to the biological characteristics of cucumber varieties and cucumber physiology.

Cucumber growing environment and many other factors. Therefore, to prevent or avoid normal circumstances, cucumbers should be fragrant and slightly sweet, and the bitterness of cucumbers is mainly related to bitters, and the reasons for the high content of bitters are also caused by several reasons. In the fruits of growing plants and propagating and reproductive, cucurbitacin is also called bitter, and a very low amount of cucurbitacin can cause obvious bitterness.

Because plants need a lot of water to transport during growth, they are resistant to development.

A lot of cucurbitacin is diluted and stored in the whole part of the plant to share, in the plant growth of a variety of external life will have a bitter taste, encounter this phenomenon, many people do not know why, in fact, bitterness is a disease to put it bluntly, and the bitterness is more important is a sense of achievement, every time I see a variety of vegetables I grow luxuriant, green, that heart is really beautiful, but there are also unsatisfactory places, there are many people who encounter cucumbers look watery, but they eat bitter, affecting the taste. <>

Once there is too much accumulation in cucumbers, it will taste more bitter, and generally speaking, there are still many bitter factors that cause cucumbers. Most people know that cucumbers on the market are crisp, sweet and juicy, but few people know that they have a bitter taste, but as someone who has grown cucumbers, I know that bitter cucumbers do exist. It can be eaten, but it only affects the taste, but if the spleen and stomach are not good, people who like cough should eat less.
