Special drought-resistant fertilizer for rainfed wheat and preparation method thereof

Abstract

The invention specifically provides a special drought-resistant fertilizer for rainfed wheat and a preparation method thereof, and aims at solving the problem of unreasonable fertilizer for existing rainfed wheat influences the seedling condition and water utilization rate. The compound and mixed fertilizer is prepared from the following raw materials in parts by mass: 12 to 16 parts of urea, 17 to 20 parts of diammonium phosphate, 4 to 5 parts of potassium chloride, 0.7 to 1 part of water-retaining agent, 1 to 2 parts of fulvic acid, 0.1 to 0.3 part of manganese sulfate, and 0.1 to 0.2 part of ferrous sulfate; the organic biological material is prepared from the following raw materials in parts by weight: 2 to 4 parts of decomposed coal, 5 to 7 parts of chicken manure, 1 to 2 parts of maize straw, 0.5 to 1 part of wheat bran, 0.1 to 0.3 part of diammoniium sulfate, 0.1 to 0.3 part of decomposing microbial agent, 0.1 to 0.3 parts of functional bacteria, and 0.2 to 0.3 part of pyroligneous; diammonium phosphate contains 18% of nitrogen, and 46% of phosphorus pentoxide; potassium chloride contains 60% of potassium oxide; the purity of fulvic acid is more than 90%. The fertilizer promotes balanced growth, improves the drought resistance and stress resistance of wheat, and achieves continuous yield increase.

Description

technical field [0001] The invention relates to agricultural production technology, in particular to a drought-resistant special fertilizer for dryland wheat and a preparation method thereof. Background technique [0002] Fertilizer is the most important means of production in agricultural production and the key to high and stable crop yields. It is called the "food" of plants. According to FAO statistics, chemical fertilizers have brought about 55% increase in food production in developing countries. Fertilizer properties, soil environment, and application methods all directly affect the yield increase effect and utilization efficiency. [0003] Dryland wheat belongs to rain-fed agriculture, and the growth and development of wheat depends entirely on natural precipitation. Rain-fed dryland adopts measures such as increasing soil water storage, choosing reasonable fertilizer types, rational application, and appropriate planting at the right time through reasonable cultivati...
