Mr. Gao, the amaranth grower, planted more than one mu of amaranth this year. After planting it for several years, he began to doubt his life. It turned out that the amaranth he planted this year was very weak, and the leaves were dark green but not shiny, and it felt like sick. Looking at the problem carefully, the amaranth in the alkaline soil will definitely show this phenomenon. First, what kind of soil is suitable for amaranth? The root system of amaranth is relatively small, suitable for relatively fertile, breathable soil growth. The soil with heavy soil and poor drainage will shorten the life of amaranth and affect the quality of amaranth. The soil acidity and alkalinity is the best. Second, the characteristics of alkaline soil Soil viscosity and permeability are very poor. Such soils will affect the growth of amaranth roots, causing the roots to absorb nutrients, so that the growth of amaranth is slow, the leaves are not shiny, and they look like sick. Such amaranth not only has low yield but also poor commercial properties. In fact, Mr. Gao’s unsuccessful cultivation of amaranth is mainly due to the lack of relevant planting knowledge. It can be seen how important it is to learn about the cultivation techniques in the Huinong School! Third, how to solve the alkaline soil amaranth Try not to use alkaline fertilizers, and use organic fertilizers and acidic fertilizers. Gypsum can also be used to improve the soil. Agricultural gypsum is both a fertilizer and a good soil conditioner. The main component of gypsum is calcium sulphate, which contains a lot of calcium and sulphur. It is a good fertilizer and has a good effect on improving alkaline soil. Why does gypsum improve alkaline soil? Sodium carbonate in the soil can react with calcium sulfate, the main component of gypsum, to form sodium sulfate which is easily soluble in water. Sodium sulfate can be washed away with water by irrigation, thereby eliminating alkalinity in the soil layer and improving alkaline soil. the goal of. After improving the soil, Mr. Gao can also produce green high-quality leeks, and this year's leeks can still make a small profit! nucleic acid extractor specifically adsorbs nucleic acid molecules in samples through magnetic beads, and then adsorbs transfers magnetic beads through the movement of magnetic rods in different holes, so as to achieve the purpose of purifying nucleic acid molecules. Former 1B48 nucleic acid extractor instrument can automatically extract nucleic acid from whole blood, bacteria, plasmid, virus, serum free and plant samples, widely used in scientific research, CDC, food safety, clinic testing, forensic medicine, and other fields.
