The embodiment of the invention provides a variable fertilization method based on crop seedling condition information and a device. The fertilization method comprises the steps that the historical yield information and seedling condition information of crops in a preset region are obtained, and a fertilization base map for fertilization of the preset region is generated; real-time growth information of crops in the current block corresponding to the preset region is obtained, and a fertilization prescription map for topdressing of the current block is obtained based on the fertilization base map; and real-time variable fertilization is carried out on the crops based on the fertilization prescription map through combination of the operation position and the running speed of the fertilization device. According to the method and the device, during fertilization, the soil fertility distribution of the field and the current growth condition of crops are comprehensively considered, and therefore the fertilization amount is finely controlled according to the seedling condition information of different blocks of the field based on the total fertilization amount distribution of the whole field, and more fertilization of weak seedlings and less fertilization of vigorous seedlings are realized; and the efficiency of fertilizer is fully exerted under the condition of ensuring uniform cropgrowth vigor.
Description
technical field [0001] The invention relates to the technical field of agricultural top dressing, in particular to a variable fertilization method and device based on crop seedling condition information. Background technique [0002] Crops have different requirements for nutrient elements in different growth periods. In order to meet the growth needs of crops, it is necessary to carry out corresponding topdressing operations in different growth periods of crops. The traditional topdressing operation is mainly based on manual spreading, which is not only time-consuming, laborious and inefficient, but also often manually topdressing field crops based on experience, and topdressing is not accurate. In recent years, along with the improvement of the level of agricultural mechanization, there has been a topdressing operation device for spraying fertilizer on crops. Although this topdressing operation method has improved operating efficiency, the utilization rate of fertilizer ha...
