Method for fertilizing according to soil condition

Abstract

The invention provides a method for fertilizing according to a soil condition. The method comprises the following steps: (1) sampling greenhouse plant planting soil; (2) testing nutrient information in the soil; (3) determining fertilization information according to the nutrient information of the soil and plant types, wherein the fertilization information comprises fertilization components and fertilization amount; (4) preparing a fertilizer according to the determined fertilization information; (5) applying the fertilizer directly into the soil; (6) watering the soil thoroughly; and (7) repeating the above steps (1)-(6) in each growth period of a plant, and fertilizing under different soil conditions in different growth periods, wherein the growth periods comprise a germination stage, aflowering stage, a young fruit stage, a vigorous growth stage and a maturation stage. According to the method provided by the invention, targeted fertilization can be carried out according to the nutrient information in the soil, which is beneficial to plant growth. The method provided by the invention can be conveniently applied to the field of greenhouse planting.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for fertilizing according to soil conditions. Background technique [0002] When the soil cannot provide the nutrients needed for crop growth and development, the act of supplementing the crops with artificial nutrients is called fertilization. Increase soil nutrients No matter the application of organic fertilizers or inorganic fertilizers can increase soil nutrients. Most of the inorganic fertilizers are easy to dissolve, and the crops can absorb them immediately after application, except that they are partially absorbed by the soil. For organic fertilizers, except for a small amount of nutrients that can be directly absorbed by crops, most of them must be decomposed by microorganisms before crops can use them. [0003] The current method of fertilizing greenhouse plants is still basically in the manual mode. Different diameters and different types of greenhou...

Problems solved by technology

The traditional fertilization method makes the amount of fertilization inaccurate, the fertilization is not very targeted, and the fertilization cannot be carried out according to the soil nutrition, and the quality and yield of greenhouse plants cannot be improved.
