Skillful use of calcium Fertilizer to increase yield of Peanut

Last Updated: 2024/11/22, Peanut root-knot nematode disease is an important disease of peanuts, generally reducing yield by 2030%, serious cases up to 70,80%, or even no harvest. First, the symptom of this disease mainly harms the root, any part of peanut that can be buried (roots, pods, etc.) can be damaged by nematodes. Half a month after sowing, when the main root of peanut begins to grow, the line.

Peanut is a calcium-loving crop. Calcium fertilizer can promote peanut root growth, increase root activity, prevent peanut premature senescence, promote peanut kernel fullness, increase 100-grain weight and protein content, and enhance peanut disease resistance. The application of this fertilizer to peanuts should be due to the fertilizer system of the soil: because peanuts are not tolerant to saline-alkali, acid fertilizers containing calcium should be applied on saline-alkali soils lacking calcium, which can not only meet the nutritional needs of peanuts for calcium, but also neutralize the soil. alleviate and correct the harm of saline-alkali to peanuts. Should be timely applied: because peanuts in the growth of new roots, young roots, fruit needles, absolutely can not lack calcium, so the time of calcium application, that is, should do the base fertilizer early application and flower and fruit needle just appeared topdressing, applied twice. To apply an appropriate amount: general acid soil lime 50-60 kg per mu, or calcium magnesium phosphate fertilizer 35-40 kg, alkaline soil can apply 30 kg calcium superphosphate per mu. The application amount of calcium fertilizer should not be too small, otherwise, the yield increase is not obvious. Do not have too much, otherwise, it will not only cause waste, but also destroy the soil structure and reduce the economic benefits.
