Wild vegetables---cutting techniques of purslane

Portulaca oleracea is an ancient vegetable and medicinal plant in China, and its main edible parts are tender stems and leaves. All regions are wild, but the wild purslane has low yield and poor palatability and should not be promoted. Compared with wild purslane, artificially cultivated purslane plants grew upright, thick stems, large leaves, high yield, and good quality, but their resistance to disease was less than wild purslane. In 2003, we introduced vegetable purslane from Russia to carry out asexual reproduction experiment and achieved success. It is now described as follows: Purslane is a short-day crop, which should be planted locally from April to July and harvested from May to September. The purslane has always been dominated by seed breeding, but since the seeds of purslane are small, it is difficult to harvest, and the dormancy period is longer. Therefore, in the absence of provenance in the growing season, the use of asexual propagation methods is undoubtedly an improvement in reproduction. Rates, effective measures to reduce production costs. 1, the selection of cutting materials. The above-ground part of the purslane plant can be used as a cutting material. The long shoots can be cut into multiple sections. The lateral branches can be inserted from three pairs of true leaves to eight pairs of true leaves. However, there are five pairs of true leaves. The survival rate of the top branch with the length of 12-15 cm is the highest. When picking seedlings from the maternal bed, it is necessary to pick from disease-free plants and select lateral branches with thick stems and strong growth, which can be cut and inserted, and can also be placed after 1 day, which has no significant effect on the survival rate. 2, Daejeon preparation and cuttings. Although the adaptability of purslane is not strict with the soil, it is better to use organic-rich sandy loam for high yield. The purslane is not as resistant as it is wet, so it is necessary to choose a plot that is close to the water source and is convenient for irrigation and drainage. Ploughing and hoeing, hoeing and finishing, full-scale fine soil, smooth surface, and 1.5-2 meters wide. Before the preparation of soil, apply sufficient organic fertilizer as base fertilizer. After cutting, the cuttings can be cut and inserted. The cutting density is generally about 40,000 per acre, and the row spacing is 13 cm 13 cm. 3, management after cutting. In the hot season in summer, the shaded net shading shall be covered in the front shed to increase the survival rate, and there is no need to cover the shade net in spring and autumn. Plug water in time to promote the tree. Under appropriate temperature conditions, cuttings usually grow new roots after 3 days, and the shade nets can be removed in about 1 week. Uncovered nets should be carried out after 4:00 pm. Diluted or diluted 0.4% urea solution after survival to promote growth.

Vitamin

Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
