Peanut requires more phosphate fertilizer than general crops, and the absorption and utilization rate of phosphate fertilizer is also high. The test proved that 10 kg of calcium phosphate per acre was applied, the yield increase effect was remarkable, and the aftereffect was obvious. When the phosphate fertilizer is applied in a thin manner, 2.5 to 5 kg of urea per acre is added as a seed fertilizer, and the effect of increasing the yield of the phosphate fertilizer can be exerted. However, when applying the seed fertilizer, the fertilizer and the seed should be isolated to avoid harming the seed and affecting its germination and emergence.
Peanut application of calcium sulphate 10 kg per acre can not only adjust soil pH, improve nitrogen fixation capacity of rhizobium, but also improve nitrogen nutrition, promote pod development, and reduce empty fruit and rotten fruit.
Artificial inoculation of peanut rhizobium can make early nodule and multi-root nodule of peanut, and improve the nitrogen fixation ability of peanut plants. At present, the peanut rhizobium agent (rhizobial fertilizer) is generally used for 25 grams per acre. When using it, add appropriate amount of water to make a paste and mix well with seeds. Pay attention to mixing with seeds to prevent sun exposure. Also avoid mixing or contact with fungicides.

2. The glass slide is at the bottom, which is the carrier for the material you want to observe, that is, you want to put something on it.
3. The cover glass is smaller than the slide glass. The glass slide is mainly used to hold the observation objects. The cover glass is covered on the slide glass and used for fixing.
4. The glass slide is a thicker piece of glass in the transfer slide, which is used to carry the real object. The cover fragment is the small round or square thin one.
5. Mounting is a general term for a set of things, including slides, coverslips and loaded objects
Spring peanuts should be added with phosphate fertilizer
The amount of base fertilizer should account for 80% to 90% of the total amount of fertilizer. Some peanut fields only apply base fertilizer, and high yields can be obtained without top dressing in the later stage. The base fertilizer can be used for 1000-3000 kg of high-quality ring fertilizer per acre.
