The leeks, also known as horseshoe grass and watercress, are perennial rooted water herbaceous plants of the Nymphaeaceae. The edible parts are young shoots and primary leaf curls. Due to its tender texture and green color, leek is also accompanied by a lot of transparent gums, which makes the soup smooth and delicious. Its high quality and high yield cultivation measures:
Cultivating strong seedlings is the key to high quality and high yield of spinach. Nursery uses asexual and sexual two methods, generally using vegetative propagation, also known as stem propagation. Select a thick soil with rich humus content, but the mud is not too deep for the seedbed, the seedbed is well-organized, the base soil is fully used, the seedbed is equipped with a good base fertilizer, and a plastic scaffold is set up. The plant was inserted obliquely on the bed and covered with plastic film. After the nutrient strain grows to a certain length, it is planted in depth.
The cultivation of high-yielding cultivated fields of leek is an important measure for the high quality and yield of leek. The leek hi warm and wet, growth and development process need suitable strength, clarification of water quality, fertile soil and other environmental conditions. Planted plots should be selected for industrial plots that are free of industrial pollution, and that can be used to fill irrigation fields that are not in water all year round. First of all, it is necessary to reinforce and shape the field hoe, 1 meter deep, so as to prevent water leakage, build irrigation drainage rakes, and cultivate the thick soil layer in the field. Requires fertile loose soil 10 to 14 cm, containing 2-3% organic matter, PH4-6. Per acre with a heap of manure 1500 kilograms of cooked manure or sheep 1500 kilograms of sheep, cooked cake fertilizer 50 kilograms, compound fertilizer 20 to 25 kilograms as a base fertilizer; Third, disinfection and sterilization. Copper sulphate, grass ash, snails, rapeseed cakes, etc. were used to sterilize cultivated fields. Fourth, chemical weeding was used. Before the leeks were transplanted, the acres were sprayed once with 150 kg of potassium tetrachloride and 25 kg of water and 25 kg of water.
Transplanting timely. The leek can be planted all year round, especially in the spring before transplanting, the survival rate is highest, and it can be harvested in the same year. The best time is usually from late March to mid-April. When transplanting, the seedlings were cut into 2-3 sections of each section. The planting was conducted using a hole, one for each hole, and the distance was 30 cm. The plant was inserted into oblique water.
Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
