Peanuts lack calcium, plant growth is slow, roots are thin and weak, old leaves have irregular white spots on the edges and leaves, petiole weak, new leaves are small, affecting peanut production. Calcium can promote the formation of pods, reduce empty pods and increase the number of full fruit. The use of calcium fertilizer lime in acidic soils can also reduce soil acidity and favor nodule nitrogen fixation.

Lime and plaster can be used as base fertilizer and top dressing. Acidic soil generally uses about 50 kilograms of lime per acre, which is used as a base fertilizer when combined with cultivated land. When used as a top dressing, it can be applied in the first cropping stage in combination with cultivator soil. Lime in slightly acidic soil should be applied once every 2-3 years. It cannot be applied year after year to prevent soil compaction. Gypsum is generally applied in alkaline soils. In saline-alkali soils, there is also the adjustment of pH and the reduction of the toxic effects of salt and alkali on peanut roots. In neutral and slightly acidic soils, gypsum can also be applied. Generally, 5-7.5 kg of Mushi is applied.

Breathing filters

Breathing filters provide an effective barrier that prevent cross contamination between patients, breathing systems, respiratory and anaesthetic equipment, and the clinical environment. They are widely used across the hospital particularly in the operating theatre, critical care, lung function units, and respiratory care units.

We offer a wide and comprehensive choice of breathing filters with a variety of filtration efficiencies, sizes, volumes and shapes to ensure maximum customer choice.
