Peanut planting technology: what is the use of applying calcium fertilizer to peanuts?

What's the use of applying calcium fertilizer to peanuts? Ask netizens to explain the reasons why peanuts apply calcium fertilizer: peanuts are calcium-loving crops (it is determined that for every 100 kilograms of peanut pods, 2.7 kilograms of calcium is needed). Calcium is needed when seeds germinate; calcium can strengthen the metabolism of nitrogen in the plant and promote the development of roots and nodules. When peanut was deficient in calcium, the root system was weak, the young stems and leaves were yellow, spots appeared on the back of leaves, the germ of seeds blackened, the development of pods decreased, and the number of unblighted fruits and single kernels increased. The method of applying calcium fertilizer to peanut: at present, the calcium fertilizer applied in production is mainly gypsum (that is, calcium sulfate), which can be used as base fertilizer, 50kg / mu and 100kg / mu; it can also be used as topdressing and ditching in the fruiting area at the early flowering stage of peanut, the application rate is 20kg / mu. The application of gypsum to peanut in saline-alkali soil can also adjust the soil acidity and alkalinity and reduce the harm of excessive sodium salt to the root system. According to comparative tests in various places, peanuts with calcium fertilizer generally increase production by 5% to 20%, and those with high calcium fertilizer can reach more than 30%.
