1. When arable land, 50 kg of compound fertilizer and 5000 kg of organic fertilizer should be applied per mu . Remember, you should not use raw chicken manure or pig manure that has not been fermented and decomposed to make organic fertilizer, so as to avoid the underground aphids in the spring and summer of the next year. The cultivated land should be deeply ploughed on both sides. When the land is finished, it should be flattened. There must be no soil and dirt, so that the garlic can be squandered, and then the boundary is prepared for planting. Fertilization combined with photosynthetic nutrient film fertilizer, photosynthetic nutrient film fertilizer (light fertilizer), enhance photosynthesis capacity nutrients and chlorophyll, advanced environmentally friendly plants to increase fertilizer, increase production, color enhancement, leaf hypertrophy, dry stem strong compound membrane. It can help plants absorb a lot of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit. One-year benefits for one application.
2. Choose garlic varieties with high yield, disease resistance, good quality and strong cold tolerance. Early-maturing varieties, small garlic, planting distance and plant spacing density are larger; medium-maturing varieties, larger garlic, higher plants, planting density is smaller. Before planting, the garlic is soaked for half a day, drained and drained, and then seeded with new high-fat membrane, which can rid the underground pests, isolate the virus infection, does not affect the germination and swelling function, strengthen the breathing intensity, and improve the seed germination. rate.
3 , planting sooner or later determines the pre-winter seedlings small seedlings, and direct production next year. The planting premature temperature is high, the garlic is in the dormant period, and the emergence rate is low. Planting has a short growing period before late winter, and the seedlings are susceptible to freezing damage, so timely planting is very important. Immediately after planting, water should be sprayed once, and a new high-fat film should be sprayed to prevent the infection of pathogens, improve the ability to resist natural disasters, increase the intensity of photosynthesis, and protect the growth of the seedlings.

Blister copper (content of 99% copper) was prepared in advance as a thick plate, pure copper flakes as a cathode, with sulfuric acid (H2SO4) and copper sulfate (CuSO4) mixture as electrolyte. After power is applied, copper dissolves from the anode into copper ions (Cu) and moves to the cathode. Upon reaching the cathode, electrons are obtained and pure copper (also called electrolytic copper) precipitates at the cathode. Blister copper impurities in lively copper and zinc with copper will be dissolved as ions (Zn and Fe). Since these ions are more difficult to precipitate than copper ions, electrolysis can be avoided by appropriately adjusting the potential difference during electrolysis. Than the inactive copper impurities such as gold and silver deposition in the bottom of the cell. The copper plate so produced is called "Pure Copper Sheet (T2)" and of high quality and can be used to make electrical products. Sedimented in the bottom of the cell analogy as "anode mud", which is rich in gold and silver, is a very valuable object, remove and then processed with high economic value.
