White cucumber is a type of cucumber, and its main cultivation techniques are now described as follows: 1. Apply basic fertilizer to high-yield farmland and require 5000kg of quality farmyard fertilizer per 667m2, 50kg of NPK fertilizer compound fertilizer, 20～50kg of superphosphate, even spreading, deep soiling after 25cm, soil preparation. Flat width 1.1 ~ 1.2m. 2. Timely sowing, nurturing strong seedlings Huang-Huai River spring open field cultivation can be planted in mid-March, autumn planting in mid-June to late July seedling or live, available sawdust seedlings, sawdust ventilation, insulation, moisture, seedlings unearthed Fast and strong, and it is not easy to hurt the roots. Strong seedlings require about 1cm thick stems, short internodes, about 10cm long, about 10cm petiole length, there are 4 to 5 true leaves, horizontal unfolding, hypertrophy, color green, large crown without sharp, roots, thick The color is whitish and the melon seedlings grow strong and solid. 3. Reasonable dense planting This species has a strong growth potential. In order to increase the utilization of light energy, the spacing between the rows is 30cm60cm, and about 3700 strains of seedlings of 667 square meters are cultivated. 4. Scientific pruning Because the main vines of this variety can produce melons, in the spring cultivation, the seedling stage generally does not pick up the heart, and when the main vine reaches the top of the rack, it will pick up the hearts. For high-yield cultivation, the "one main and two sides" type can be used for pruning so that it can be evenly distributed on the surface of the frame, and light energy can be fully utilized to synthesize more nutrients. 5. Strengthen the management of fertilizer and water During the growth of cucumber, it is necessary to promote the control of the combination, so that the melons are flourishing, the early cultivator is strengthened, the seedlings are planted, and the seedlings are planted to reach the root melons. If the water is too early, it is easy to cause the plants to grow in size, and the risk of the emergence of melons. The initial flowering period is dominated by "control," and the melon period is mainly promoted. The top dressing principle is diligent application and thin application. After the roots are harvested, adopt the “one clear and one mixed†alternately and follow the water topdressing urea, 8 kg for each 667 square meters or 20 kg of ammonium bicarbonate, so as to obtain stable production and high yield. 6. Control pests and diseases White cucumber diseases mainly include downy mildew, keratopathia, powdery mildew, etc., and can be sprayed with Dubangkeluo, Ank manganese zinc, metalaxyl, dt fungicide, streptomycin, thiophanate methyl , triadimefon and other prevention and treatment. Insect pests mainly include aphids, Huangshougua, black pawed melons, etc., and can be controlled by insecticides such as dimethoate, alkaloids, trichlorfon, and beta-cypermethrin. 7. Timely harvesting of cucumber is the use of tender fruits for vegetables. When the length and thickness of the melon strip grow to a certain size, and the seed and epidermis have not yet hardened, they should be timely harvested, too late will not only affect the quality, but also fall Hey, it will delay the development of the next melon, especially root melon harvesting should be properly advanced. White cucumbers typically produce 667 square meters of 3000 to 4000 kg. Disclaimer: Some articles in this website have been transferred from the Internet.

Generally, food additives may not be food and may not have nutritional value, but they must conform to the concept of the above definition, that is, do not affect the nutritional value of food, and have the function of preventing food spoilage, enhancing food sensory properties or improving food quality. buy food Additive ,wholesale food Additive,food Additive for sale,food additive benefits Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptide-nootropics.com
Generally speaking, food additives can be divided into natural and synthetic categories according to their source. Natural food additives refer to natural substances extracted from the metabolites of animals, plants or microorganisms as raw materials. Chemically synthesized food additives refer to substances obtained by chemical means through oxidation, reduction, condensation, polymerization, salt formation and other synthetic reactions of elements or compounds. Most of the chemicals used today are synthetic food additives.
According to the use, the classification of food additives in various countries is almost the same, the difference is mainly the difference in the classification of how much. The United States divides food additives into 16 categories, Japan into 30 categories, China's "Health Standards for the Use of Food Additives" divides them into 22 categories: Antioxidant preservatives (1) (2) (3) (4) bleach hair color agent (5) concreting citric acid (6) (7) loose agent (8) thickening agent defoaming agent (9) (10) sweetener (11) colorants emulsifier (12) (13) improver (14) anticaking agent (15) flavor enhancer (16) (17) of enzyme preparation was preparing foaming agent (18) (19) preservatives (20) spices (21) nutritional fortifier (22) other additives.
