Description
Technical Field
The invention relates to the technical field related to agricultural instruments, in particular to a wheat layered fertilizer applicator.
Background
The wheat topdressing urea is good for helping the growth of wheat, but if the application method is not noticed when the wheat is topdressed with urea, a good effect cannot be obtained, as is well known, the urea is high in nitrogen content and very wide in application range in wheat planting, the urea is mostly used for topdressing of wheat except for base fertilizer of crops, and deep application and soil covering practices prove that most of nitrogen is aminated and volatilized after the urea is applied to the ground surface for 4-5 days at normal temperature, the utilization rate is only about 30%, and particularly on the surface of calcareous and alkaline soil, the volatilization loss of ammonia is more serious. Therefore, when the dry field crops are fertilized with urea, the urea is preferably dug or ditched deeply, so that the urea can be in moist soil, the urea is favorable for conversion of the urea, the ammonia fertilizer is also favorable for being adsorbed by the soil, the volatilization loss is reduced, as is known, after the root system of the root of the wheat grows out as the first green leaf, the initial root of the wheat seedling is not increased, the initial root of the spring wheat is generally 5, the number of the large and full seeds can reach 7, the maximum number of the large and full seeds can reach 8, the secondary root grows on the tillering section, the secondary root begins to appear after the three-leaf stage, is related to tillering, and the root is continuously grown under the proper condition. When one tillering grows, 1-2 roots correspondingly grow on the same section. The spring wheat root has stronger growth vigor than tillering, tillers do not appear, but roots grow, so the number of secondary roots is often more than that of tillers, and sometimes only roots grow for a plurality of times on tillering joints without tillering. The secondary roots growing in tillering grow from the base of the main stem, and when three tillers grow, the secondary roots of the tillering grow. Because, spring wheat is less tillering by virtue of the main stem supplying water and nutrients. After jointing, nutrients are concentrated at the top end, so that smaller tillers die in succession. At the moment, the secondary roots of the wheat are stronger than the primary roots, but the soil is shallow and mostly concentrated in a 0-30 cm ploughing layer, the number of the roots is much larger than that of the primary roots, the secondary roots play roles of plant fixing and nutrient absorption, and the growth basically stops when the wheat blooms. Therefore, the key point of improving the utilization rate of urea or nitrogen fertilizer is that nitrogen fertilizer can be applied to a specified ideal soil layer according to the specific characteristics of the root system of the wheat in each growth period.
