Special-purposed solid fertilizer used for potato seed tuber supplementary irrigation

Abstract

The invention relates to a special-purposed solid fertilizer used for potato seed tuber supplementary irrigation. The special-purposed solid fertilizer is prepared from doped components of inorganic nitrogen fertilizers, inorganic potash fertilizers, inorganic phosphate fertilizers, and chelate medium and micro fertilizers. The total content of main nutrients comprising N+P2O5+K2O+medium and trace elements in the special-purposed fertilizer is no less than 43.1%, wherein nitrogen takes 12.42 to 21.84%, phosphorus pentoxide takes 6.97 to 16.07%, potassium oxide takes 7.1 to 21.52%, calcium takes 0.89 to 1.1%, magnesium takes 0.58 to 0.84%, sulfur takes 0.88 to 8.8%, iron takes 0.10 to 0.14%, manganese takes 0.13 to 0.15%, copper takes 0.13 to 0.17%, zinc takes 0.29 to 0.32%, boron takes 0.07 to 0.1%, and molybdenum takes 0.004 to 0.006%. According to the invention, the production area soil nutrient supplying condition is taken into consideration, nitrogen fertilizers and phosphate fertilizers are increased, and potash fertilizers are appropriately supplemented, such that the loss of medium and micro fertilizers is prevented. The fertilizer provided by the invention has characteristics of comprehensive and balanced nutrients, good specificity, high nutrient concentration, complete ionic state, environment protection, no pollution, low cost, simple preparation technology, and the like. With the fertilizer, potato yield can be improved, potato quality can be improved, agricultural investment can be reduced, and ecological environment can be improved.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizer production, in particular to a solid special fertilizer for seed potato supplementary irrigation. 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 of N is neede...
