The purslane is a kind of wild vegetable that our country people like to eat since ancient times and has the effect of detoxification, anti-inflammatory, diuretic and analgesic. Family potted purslane, safe, sanitary, easy to eat. Its technical points are:
First, the choice of species. In China's rural areas, there are wild species of purslane in the fields, roadsides, fields, courtyards, and vegetable gardens. When they are used as vegetable pots, they should use large, thick, leafy leeks. In recent years, the excellent varieties of purslane for vegetables grown in the Netherlands have entered China. Compared with wild species, they have unique flavor, rich nutrition and higher yield. The optimum temperature for the growth of purslane is 20-30°C. As long as the temperature is not lower than 15°C, it can be sown at any time and harvested in stages.
Second, basin soil preparation. Pots used to cultivate purslane should not be too small, and the diameter of 35-40 cm mud pot is most suitable. The purslane grows robustly and does not require strict soil requirements. However, the use of loose, fertile, well-conditioned sandy loam cultivation, accelerated growth, young stems and leaves, particularly good quality. The purslane enjoys good water, and it is resistant to light, especially in the air-dry and soil-humid environment. Pay attention to places where sunlight can shine, which will help stems and leaves grow. Under low light, purslane grows fast and young, and when light is too strong, it is easy to age.
Third, planting methods. Potted purslane uses a lot of layers and sowing two breeding methods. The batten is to overwhelm the long stems of the plants and press the stem segments at intervals of 3 knots with wet soil. The roots of the shoots at the soil are separated from the main body to form new individuals. Sowing should be carried out when the temperature exceeds 15°C. Before sowing, the potted soil shall be poured into the bottom water. After the water is soaked, the seeds are mixed with the fine sand and sowed, and then covered with 0.5 cm of finely screened fine soil. After sowing should pay attention to insulation moisturizing. 2 to 3 days after sowing can emerge. Seedlings emerged 7 days after emergence, and the spacing was about 3 to 4 cm. When the seedling height is about 15 cm, the young seedlings are started to be eaten and the plant spacing is kept between 7 and 8 cm. During the growth, keep the soil moist. Fertilizer application requires thin fertilization, once a week, with no more than 50 urea tablets per pot.
Fourth, pest control. The purslane has almost no pests and diseases, and occasionally has viral diseases, powdery mildew, and leaf spot. It can be controlled by thiophanate-methyl, triadimefon, chlorothalonil, quick-acting, carbendazim and other pesticides.
V. Harvesting methods. About 30 days after sowing or planting, stems and leaves have been fully grown, when the plant height is about 25 cm, the weight of a single plant is 35 to 40 grams, and the stems and leaves are thick and thick and young and juicy, and they have not been harvested when buds emerge. Potted purslane should pay attention to leave three main stems at the base of the plant for easy growth and harvesting. Do not water after harvest, to dormant bud germination after pouring water, topdressing nitrogen fertilizer. Three days before harvesting, spraying 30 ppm of 920 solution on the leaves not only increased the yield by about 30%, but also the plants were tender and the quality was improved.
Sucralose is an artificial Sweetener. The majority of ingested sucralose is not broken down by the body, so it is noncaloric. The commercial success of sucralose-based products stems from its favorable comparison to other low-calorie sweeteners in terms of taste, stability, and safety . Sucralose is approximately 600 times as sweet as sucrose (table sugar)
