We introduce several methods of applying ammonia water to main crops
Various crops have different characteristics of fertilizer requirements. In order to give full play to the fertilizer effect of ammonia water, it should be applied reasonably according to the fertilizer requirements of crops.
Winter wheat:
In order to increase wheat production and a bumper harvest, in addition to deep ploughing and soil improvement, selection of improved seeds, and strengthening of field management, increasing the application of fertilizers, especially nitrogen chemical fertilizers, has a great impact on increasing wheat production. According to the analysis of Shandong Academy of Agricultural Sciences, at the level of 609.6 catties per mu, wheat absorbs 16.84 catties of nitrogen from the soil, and every 100 kg of seeds absorbs 2.8 catties of nitrogen. High-yield experience in various places has proved that applying enough nitrogen fertilizer and applying phosphorus and potassium fertilizer is one of the key measures to obtain high wheat yield
On the basis of applying farm fertilizer, qualified units can apply a certain amount of ammonia water as base fertilizer. Generally, 30 or 50 kilograms are applied per mu, and the fertilization method is applied when ploughing the land. It can also be applied in furrows such as machine-induced ammonia fertilizer applicator or ammonia water aquileg. The depth of fertilization should be less than 10 cm, and the soil should be covered with fertilization to prevent the volatilization of ammonia.
Topdressing with ammonia water should be applied before winter, before turning green and before jointing, and topdressing with ammonia water according to the growth of wheat seedlings. Generally, 30 or 40 kilograms of ammonia water is topically applied each time. The forced application method can be applied by ditch or flushed with water; in units with the habit of spraying in the south, the method of spraying can also be used, but attention should be paid to the multiple of water added, and the Fertilize when the temperature is low.
