The bitterness of melons is due to the presence of a substance known as bittersin in their plants. The substance is the highest in the base of the cucumber stalk, and can be inherited, and its content varies according to the type, variety, and cultivation conditions of the vegetables. Excessive consumption of bitter melon can cause vomiting, diarrhea, sputum and other symptoms of poisoning. Therefore, during the cultivation of cucumber, necessary measures should be taken to eliminate the formation of bitter melon and ensure food safety. The main measures are as follows:
Avoid low temperature or high temperature First, when the temperature or ground temperature is lower than 13 °C, the cell permeability decreases, nutrients and water absorption is inhibited, cucumbers are susceptible to bitterness; Second, the greenhouse temperature is higher than 30 °C and the duration will lead to cucumber Bitter. Therefore, we must try our best to increase the temperature and heat preservation performance of the protection facilities, adjust the temperature, and avoid the temperature boundary formed by bitterness.
Watering should be reasonably timely First, when the temperature is high and the soil moisture is low, the plant physiological drought occurs, and it is easy to produce bitter melon. At this time, the cucumber must be supplied with water in time to maintain the turgor of the plant tissue and the stability of the plant body temperature. Second, the watering should be done a small number of times, the water temperature should not be too low, to prevent the water deficit of the plant body leading to the formation of cucumber bittersin. In addition, special attention should be paid to the fact that after planting, the seedlings should not be excessive, otherwise the root melons are easy to suffer.
Fertilization to balance the amount of first, root fertilization. Seedlings should be controlled with nitrogen fertilizers to avoid plant growth. By the end of the flowering period, the ratio of nitrogen, phosphorus, and potassium uptake by cucumbers is basically 5:2:6. At this stage, it is necessary to strengthen the supply of nitrogen and potassium fertilizers. The second is top dressing. The rare earth micro-fertilizer was sprayed once at the seedling stage, the initial flowering stage, and the young melon stage; the foliar spraying was carried out with 0.5 kg of urea and 150 kg of water per mu in the flowering stage and fruit period.
Density should not be set too densely and the illumination is poor, which will lead to aggravation of the bitter taste of cucumber. Cucumber planting in protected areas should adopt the method of early close planting and late planting, that is, the common plant spacing is 26 to 30 centimeters and the row spacing is 60 centimeters. If planted at a distance of 15 cm, the "single plant" on the same ridge will not be on the shelf. When it grows to 12 true leaves, the tip will be quickly picked up and the main vine will be unpicked after harvesting. "On the shelves, when the plant grows to 1.2 meters high, it will be sharpened, making it quicker to pick up the squash, and the main vine will be unplugged after harvesting. In this way, early yield can be increased by nearly 1 times, and the occurrence of bitter melons can also be reduced.
Preventing damage to the roots and roots will increase the bitter taste of cucumbers. Seed sowing on the production of sand table sowing, to minimize the rooting when the seedlings raised, sub-plastic application of plastic nutrient pods or paper pockets, cultivation should be as far as possible mulching mulching film cultivation, shoveling should be slightly earlier, slightly shallow late.
Bitter melon can not be preserved If the bitter cucumber is left in the melon, the cucumber produced by the next generation will still have a bitter taste. Therefore, when the cucumber is about to mature, it is necessary to take a portion of the surface layer and choose a no-bitter taste.
