The weather is getting hotter and many old-town huts of cucumbers are beginning to enter the poignant season。
But the summer cucumbers are grown in the same way as the spring and autumn festival. The spring and autumn temperature is so soft that the cucumber can grow, and the cucumber can be cucumber-free; it is hot and dreary in the summer shed, and it is so damp that the light is so strong that it can easily cause problems if it cannot be managed。
The most common are saplings that grow, climb only the vines without a melon, fall flowers, cedars with cedars, deformations of the melons with sharp lips, severe outbreaks of frosty disease, pollinosis, rotting leaves, early decline in the middle and later stages and early termination of harvest。
The lack of production of cucumber in the summer season by many farmers is not due to insufficient fertilizers and poor seeds, but to poor management of hot sheds in the summer。
Today, i'm going to tell you in detail, with years of experience, with the big white words that we grow: the summer cucumbers are managed from temperature, ventilation, water, humidity, whole branches, conservative fruit, and disease-proof packages, all of which are of practical use to the land, with new hands available and managed, green cucumber blades without yellow hair, cucumbers in melons, straight bars and longer harvest periods。
First, let's figure out the root causes of the worst cucumbers in summer。
Open-air cucumbers can also cool in the summer with natural winds, and the sheds are closed, with the sun rising during the day and the temperature in the shed rising particularly rapidly. At midday, we can break 35 degrees or 40 degrees. Wet, hot and unventilated are responsible for cucumber loss, yellow leaf and illness。
The cucumbers themselves are warm, but they are the most afraid of heat and heat, the most afraid of dry and wet, and the most afraid of strong light roast. In summer, the sheds were managed with three points in their core: high temperature control, high humidity and steady movement. As long as these three dots are controlled, the summer cucumbers are as productive。
First of all, the most important shed temperature management, poor temperature pipes, and everything was in vain。
The most suitable temperature for cucumbers is between 25 and 30 degrees。
Once the temperature in the shed is longer than 32 degrees, the cucumber begins to grow, with the vines growing wildly, and the stairwells stretching, and all of them are nourished, with no flowers, no melons
At temperatures above 35 degrees, cucumber sprouts are affected, with small flowers and weak females, and prone to flowering and atrophy
Temperature lasts more than 38 degrees, and leaves are prone to high temperature burns, dry edges, yellow leaves, early decay and widespread outbreaks。
So summer cucumbers, the first thing to do is cool。
Many of the old people opened only the roof in the summer and left no air on either side, which was the greatest area of error。
Summer correct ventilation cooling:
During the day, when the sun comes out, the top and both sides of the wind are opened, forming a convection of the air and quickly draining the hot air out of the shed。
In the case of high-temperature weather, the temperature rises rapidly after 9:00 a. M., the wind is to be opened early and the air is not to wait for warmer in the shed。
Do not close the sheds immediately after the sun sets and the temperature returns. In the summer, the temperature is high, and at night there is a need for vents to ventilate and wet, to reduce the night humidity in the shed and to avoid suffocation of sick and rotten leaves at night。
Extremely hot weather, which cannot be brought down by air alone, can cover up the sunnet。
Many farmhouses are not allowed to cover their sunnets, fearing that the shades will reduce their production, but are in complete reverse。
In the summer, the sun was so bright that it was easy to burn leaves and roast melons, resulting in early fall of yellow leaves. Moderate shade, lower temperature in the shed and protection of leaf blades would instead preserve the strength and yield。
The sunnet should not be covered all day, but it should be covered from 10 a. M. To 3 p. M., with a high temperature and light, open to light and ensure normal light cooperation for cucumbers。
When the temperature is over, the summer sheds are managed with water, and during the summer cucumber leaves, rotten roots, deformed melons are mostly watered in the wrong way。
In the summer, water is grown, the most taboo of which is watering at noon, water pouring over and over。
In the summer, the cucumbers water, bearing in mind the old farmer's truth: water is watered sooner or later, water is in order, water is not dry and water is strictly forbidden。
First, water can only be poured in the morning or after sunset。
The soil in the shed is hot, cold water is pouring in, the temperature of the ground falls sharply, the cucumber root system is directly irritated, the root system is less active and absorbent, and yellow leaves and guacamole are soon emerging, long-term midday water is pouring into the water, the root is aging and decaying, and the cucumber root system dies。
Second, no big water。
The summer sheds are already very wet, with heavy water pouring in, the soil is chronically damp, the fog is high, the temperature is high, and frosty, disease and melon disease are particularly prone。
Correct practice:
The surface of the soil is dry, the soil is loose, the soil is watered again, the ground is watered down once and the soil is humid, and it is not watered or muddled。
Thirdly, heavy-rained weather has strict water control and timely drainage。
In the summer, the rains are heavy and, in the event of consecutive rainy days, the water is completely unwatered, and the drains from the sheds are pre-empted and the water is accumulated within the sheds. The cucumber roots accumulate a shortage of oxygen, which causes the yellow leaves to rot and the whole shed to decay in days。
Next, about wet management, the summer shed is very sick, all of which can't be controlled。
Cucumber water, but not humid。
Air moisture is too high in the sheds, with leaves being brought with water for long periods of time, exposed, fungi bacteria growing rapidly, and a succession of diseases。
Summer wet core method:
(b) more ventilation in the middle of the day, as well as in the middle of the air, to take away the tide from the shed
(b) water to avoid the cloud, as much as possible in the morning, and then in time for ventilation and humidity
Don't spend the night in shacks and insist on the night ventilation and wetting。
As long as the shed is not damp, cucumber disease can be reduced by half, leaves are always green and yellow leaves are rare。
Then it's summer cucumber management, which determines how much to sit on。
During the summer, the temperature was high, the cucumber vines grew particularly fast, and the side branches, rolls, and the mad scavengers rose, and if not managed in time, all the nutrients were wasted on the long scavengers, with no cucumbers and cucumbers。
Summer shed cucumber choreography:
First, to remove the extra branch in time, the inert breech. The species of the main chicken melons are removed from all the useless branches below, avoiding ventilation and nutrient consumption。
Secondly, all volumes must be strangled. The swabs merely climb wasteful nutrients, hand-belt chicken instead of a swab, and feed the whole melon。
Third, the removal of the next, yellow and sick leaves in time。
The bottom of the cucumber, which is close to the old leaves on the ground, has little light and no nutrients. It also covers ventilation, humid gas and bacteria。
The old leaves are regularly removed from the bottom, the permeability of the shed is increased, the disease is reduced, and the upper melons are fed together。
Fourth, drop the chicken in time。
In the summer, cucumbers grow fast, vines grow tall, chickens fall in time, chickens are laid at the same height, ventilated in the same light, and they are able to form normal guacamole up and down, without any conditions of upward or downward emptiness。
The whole branch works faster, with a marked increase in the density of cucumbers and little or no cucumbers。
It's about the hot summer porcupine technique that you're most interested in。
Many large cucumbers leave flowers in the middle of the summer, and the cucumbers slip off in secret, looking at the green oils of the vines, or not sitting in production。
High temperatures are the main cause of the melon. The temperature is too high, the cucumber buds are stunted, the nutrient supply is unbalanced, the guacamole is undernourished and the natural atrophy falls。
Want to sit more in the summer and do two things:
1. Tight control of the temperature of the shed, so that the temperature does not persist, the temperature is stable and the buds are stable。
2. Avoid growing up. The vines are so long, they are fully nourished, and the guacamole is not nourished, and they are bound to melt。
No nitrogen fertilisation is applied during the summer, and more nitrogen fertilizers are the easiest to grow. The proper balance of nutrients and the steady promotion of cucumbers allow them to grow in a mediocre and inert, with the natural seating of the cucumbers in guados。
And let's sum up some of the deadliest faults of summer cucumbers, which can lead to high yields。
One: the higher the temperature, the longer the temperature, the less wind
♪ high-temperature, no cucumbers, yellow leaves ♪
Zone 2: the heat is pouring water every day
(high wet roots, outbreaks, deformities)
Mistake three: no slinging, no picking
♪ unventilated, ill, sitting low ♪
Zone four: hot and rain water at noon
♪ wounded a yellow leaf ♪
We're in the middle of the night
♪ nights are wet, leaves are rotten ♪
That's the way the fields are planted. Spring and autumn depend on fertility and summer on management。
In summer cucumbers, which do not require complex techniques, the cucumbers will be green and dry, commfy, straight and continuous harvests, as long as the temperature is controlled, wet, well-watered, fast and ventilated。
