All pumpkin plants, cucumbers including produce glycoside kukurin. It is contained in the aboveground parts of the plant, but the fruits of his presence are small. This glycoside gives the bitterness of the cucumbers.
When the crop is under stress, the contents cukurlu in zelentsi is increasing dramatically. It is a defensive reaction of a culture that prevents animals eating the fruit to ripen seeds.
He kukurin has a number of useful properties:
has antitumor activity;
– exerts analgesic effects;
– has anti-inflammatory activity;
– enhances secretion of bile in the body;
– increases appetite;
– bitter cucumbers promote weight loss.
THE MAIN REASONS
Earlier there were some varieties that even under normal conditions accumulated kukurin. Now they can only meet in the gardener-the fan. The occurrence of bitter fruit is always the result of extreme situations, informs Rus.Media.
1. Sharp fluctuations in temperature.
This is a factor that people can not influence. It is only possible to some extent to mitigate the effects when the bitterness in cucumbers will accumulate less, but completely prevented the synthesis of Cukurbag in such conditions is impossible. To a certain extent can reduce the impact to a minimum by growing cucumbers in greenhouses or in warm beds. With a sharp decrease in temperature at night, the cucumber is better not to cover the film, and mulch hay. Under the grass layer heat is retained much better than a film. In the morning when the sun begins to warm, the hay is removed. Hay is the best covering material under these conditions. If not, then you can use straw, sawdust, peat. Film – the worst option in this case. Very strong temperature fluctuations provoke the increased formation of Cukurbag and its accumulation in cucumber. When the temperature becomes steady, bitter Zelentsov will not.
2. Prolonged cold weather.
Another factor that is difficult to manage. During prolonged cold, plants go into survival mode. They do their best to produce seed. In zelentsi begin to accumulate bitterness that growth is increasing.
To help the plants treated with growth stimulants EPIN-Extra or Zircon. They help with minimal losses to survive the cold period. Be sure to water organic fertilizers. Cover the cucumbers covering materials.
3. Watering with cold water.
Cold water in cucumber causing many problems. And the emergence of bitter Zelentsov – not the most difficult of them. Cucumber can not stand the cold water. Culture always watered only vistanow warm water. The temperature of the water for irrigation should be at least 20-22°C. defend It in greenhouses. If warm water is not available, it is best to boil the kettle and dilute with boiling water cold water to a temperature at least 20°C.
4. Uneven watering.
Irregular watering makes the cucumber a lot of stress that leads to increased synthesis kukurin and, as a consequence, the emergence of bitter Zelentsov.
In hot weather the plants watered daily. Watering is carried out in the morning before heat, preferably early in the morning. For each plant it is necessary to spend 10 liters of water. At temperatures above 35°C, and irrigation rate increase to 15 HP
In cold and cloudy weather cucumber watered every 2-3 days. There are oriented with the soil moisture, it should not be dry. In cool but Sunny weather, water the cucumbers every other day.
Watering must be uniform. You cannot dry up the soil, and then pour cucumbers. It is very unfavorable. If it is impossible to visit the country regularly have to do for cucumbers with drip irrigation.
5. Very hot weather and low humidity.
Cucumbers originate from India where under natural conditions they grow under the canopy of trees in the humid subtropical climate. Cottages, especially in the South when growing in the open ground plants often suffer from too dry air. For humidifying the air in ogrodniki carry out irrigation. Is it always early in the morning to before heat the water has time to dry. Otherwise the leaves may burn. Night irrigation is not carried out, because the night cucumbers secrete droplets of moisture and humidity ogrodnik increases dramatically and this can lead to the emergence of diseases.
6. Direct sun more than 14 hours a day.
Cucumbers need shading. Unlike many other plants, direct sunlight is to their detriment. In such conditions, plants begin to accumulate cucurbit, fruits become bitter and the plant itself is quickly finishes the growing season. For plants 4-5 consecutive Sunny days, to in zelentsi accumulated a significant amount of bitterness. So when growing in full sun, plants pritenyayut and agro-fibre, or a mosquito net.
7. A thick shadow.
Culture requires filtered light but not deep shade. In full shade or it will not bear fruit, or will give a small amount of bitter Zelentsov.
8. Improper seed material.
If seeds were taken from the end, where was the peduncle (tail), grown from it plants can produce bitter fruits. This characteristic is inherited. Glycoside accumulates most at the top of the fruit. Its contents to the middle of silence falls, and near the nose (where the flower) goes into oblivion. Therefore, if the seed was taken wrong, nothing can fix, the cucumbers will be bitter. It only remains to pickle the entire crop.
9. The lack of dressings.
Often cucumbers taste bitter due to lack of nutrients. Hybrids in such circumstances generally will not bear fruit, and varieties will give a small amount of immature bitter Zelentsov. If makeup is, but the power is not enough, the young fruits start to taste bitter. The amount of bitterness depends on the mineral of fasting: what it is stronger, the more bitter fruits.
If the fruits grew bitter, then it is not correct. To the next harvest had the good taste, culture must be nurtured. Most of all she needs nitrogen, so you do feeding or infusion manure (1:10) or infusion of chicken manure (1:20) or a herbal infusion fertilizer (1:10).
In addition to the nitrogen cucumbers need a lot of potassium and magnesium. Therefore, organic matter alternating with mineral fertilizers. Feeding is carried out regularly. If culture were not fed at all, then after the first fertilizer application effect: increase the quantity and quality of the crop, the bitterness will disappear, and the taste is noticeably improved. It is obligatory alternation of root and foliar fertilizing. Root feeding will be carried out after watering plants.
