The bitter taste of cucumber is caused by the bitter substance, and it has strong heredity. How can we artificially control heredity and reduce the bitter taste of cucumber? The following 10 methods are available:
Selection. The best varieties with no bitter or bitter substance content should be selected to prevent high-bitter cucumbers from being planted in Daejeon.
temperature control. In general, temperatures below 13°C or above 30°C can increase bitterness in cucumbers. Should try to adjust the temperature manually to avoid the bitter increase in temperature limits.
Scientific dense planting. Improper colonization, poor light, decreased photosynthesis, and low accumulation of dry matter can lead to increased bitterness. Therefore, cucumbers should be promoted in wide and narrow rows. General width 75 cm ~ 80 cm, narrow line 60 cm, 30 cm spacing, ensure that about 4,000 per acre colonization is appropriate.
Rational fertilization. Seedling stage should control the amount of nitrogen fertilizer to prevent plant growth, and with the continuous growth of plants, the appropriate increase in the amount of nitrogen fertilizer to the flowering period, should strengthen the nitrogen fertilizer supply and dosage, while increasing the amount of phosphorus, potassium fertilizer, and with the root top dressing.
Reasonable irrigation. It is required that there should be sufficient moisture in the tillage layer, and at the same time, because the cucumber leaves are large and thin, and the amount of transpiration is large, the air humidity is required to be large, and attention should be paid to the quantity in the irrigation water.
Scientific plug racks, tied vines, topping hearts. The insertion rack should be set up by local customs to maximize the illumination between the plants. The tying vines should be carried out after 30 cm to 35 cm in length, and tied every third or fourth quarter. When the main frame is full, it will be picked up and the seeds will be nectared to control the pods and prevent the plants from becoming leggy.
Spray production increase bacteria. The production-promoting bacteria is a new type of plant health beneficial agent. After the crop is applied, it can make the seedling stage earlier, the seedlings grow stronger, and the sweetness is increased by 15 degrees to 2 degrees. Cucumber can be seed dressing and spray treatment. The concentration is: After 15 ml of anaerobic bacteria and 50 kg of water are mixed, it can be sprayed before and after the flowering period.
Spray rare earth fertilizer. In the whole growth period of cucumber, it was sprayed once in seedling stage, initial flowering stage, and young stage, which can obviously increase the photosynthesis of plants, enhance disease resistance, and increase sugar content by 1%~2%.
Spray cytokinins. According to the experiment, during the whole growth period of cucumber, two or three times of new split antibiotics "Tong Wei No. 1" were sprayed before and after the flowering period, which can increase the yield of cucumber by more than 25%, increase the fruit setting rate by about 30%, and increase the sugar content by 1%~2%. , greatly improve the quality of cucumber.
Root-recovering sugar and nitrogen solution: In the flowering and full-fruit period of cucumber, spraying a certain concentration of sugar-nitrogen solution on the leaf surface can not only increase the yield, but also improve the quality of the cucumber, especially the sweetness and crispness. Commonly used configuration concentration is: 0.5 kg sugar plus 0.5 kg urea plus 150 kg water, mix evenly after use
