Special liquid fertilizer for potato-seeding supplemental irrigation

Abstract

The invention relates to a special liquid fertilizer for potato-seeding supplemental irrigation. The special liquid fertilizer is a liquid fertilizer prepared by matching an inorganic nitrogen fertilizer, an inorganic phosphorus fertilizer, an inorganic potassium fertilizer, a medium and micro fertilizer and water, wherein the content of total nutrients (N+P2O5+K2O+medium and microelements) is greater than or equal to 29.84 percent, wherein the total nutrients comprise 9.38-20.49 percent of nitrogen, 4.34-12.62 percent of phosphorus pentoxide, 4.7-15.28 percent of potassium oxide, 0.53-0.68 percent of calcium, 0.35-0.48 percent of magnesium, 0-4.05 percent of sulfur, 0.06-0.1 percent of iron, 0.08-0.1 percent of manganese, 0.08-0.13 percent of copper, 0.17-0.19 percent of zinc, 0.04-0.06 percent of boron and 0.002-0.003 percent of molybdenum. In the invention, by combining production-area soil-nutrient supplying levels, the nitrogen fertilizer and the phosphorus fertilizer are additionally applied in a pointed way, the potassium fertilizer is properly supplemented, the deficiency of the medium and micro fertilizer is prevented, the special liquid fertilizer has the characteristics of balanced and comprehensive nutrients, strong specificity, high nutrient concentration, totally-ionic state, environmental protection, no pollution, low cost, simple manufacturing process and the like, the yield of potatoes can be improved, the quality is improved, the agricultural input is reduced, and an ecological environment is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer production, in particular to a liquid special fertilizer for supplementary irrigation of potato seed potatoes. Background technique [0002] Potatoes are also called potatoes, artichokes, yam eggs, etc., and their edible parts are underground tubers, which are rich in starch and crude protein, and can be used as both food and vegetable feed; industrially, starch and alcohol can be produced. Potato likes a cool and mild climate. It is more drought-tolerant, stress-resistant, and high-yielding. It is suitable for planting in hills, low mountains, and alluvial plains with deep soil layers and loose structures. It is a typical high-yielding crop and is also the main potato crop in my country. A pillar industry for farmers in production areas to get rid of poverty and increase income. [0003] The growth of potatoes requires more nutrients, especially for potassium. Generally, 3.5-6.0 kg o...

Problems solved by technology

In recent years, with the construction of supplementary irrigation projects and the development of water-saving supplementary irrigation technology, the development of potato production in arid and semi-arid areas in my country has been greatly promoted. Failure to follow up in time resulted in the separation of water and fertilizer management, and the synergistic effect of water and fertilizer was not fully exerted, seriously restricting the further development of potato production in arid and semi-arid areas of my country
