Problems solved by technology

At the same time, fertilization is done blindly now, instead of requiring different fertilizers and nutrients according to the different growth cycles of crops. In this way, fertilization cannot play a real role and cannot increase income.

Embodiment 1

[0017] A fertilization method for quantitatively packaging fertilizer with filter paper, the steps of which are as follows:

[0018] (1) Measurement: At each stage of plant growth, take soil samples at different locations in the farmland, test and measure the content of nitrogen, phosphorus, potassium and other components in the soil, and calculate the average value of each content, according to the growth needs of plants in each period Nutrient composition, compared with the average value of the soil measurement data, to obtain the type and weight of various fertilizers missing in each stage of plant growth, and then decide what type and amount of fertilizer to put in the bag;

[0019] (2) Fertilization: Dig a pit above the middle part of the main stem of the plant and the side root edge. The depth of the pit should be such that the filter paper bag does not leak outside and the bottom does not touch the root. After the filter paper bag is buried, cover the soil and irrigate a...

Abstract

The invention discloses a fertilizer application method for quantitatively packaging fertilizer by filter paper. The fertilizer application method comprises the following steps: (1) measurement: testing and measuring the contents of nitrogen, phosphorus, potassium and other ingredients in soil, calculating a mean value of the contents, and obtaining the category and the weight of each fertilizer which is in shortage in each growth stage of plants according to nutrition ingredients required for the growth of a plant in each period; (2) fertilizer application: digging a hole above the middle position of a main stem and a lateral root side of the plant, after a filter paper package bag is embedded, covering soil, irrigating a proper quantity of water, and quantitatively applying fertilizer infixed time and positions, wherein the proper digging depth meets the condition that the top of a filter paper package is not exposed and the bottom of the filter paper package is not in contact witha root. The fertilizer application method has the following advantages: (1) the use ratio of the fertilizer is improved; (2) environment is protected, and pollution is avoided; (3) plant diseases andinsect pests are avoided; (4) resources are saved, and earnings are increased; (5) pertinence is high; (6) the soil is improved, and the yield of crops is improved.

Description

technical field [0001] The invention relates to the technical field of fertilization methods, in particular to a fertilization method for quantitatively packaging fertilizers with filter paper. Background technique [0002] The current chemical fertilizers and compound fertilizers are packaged in large bags. When fertilizing, they are generally sprinkled by the wrist. In this way, they are exposed to the air and are easy to evaporate and oxidize. The absorption rate of plants is very low, especially if it rains soon after fertilization. All the applied fertilizers were washed away by the rain, causing great losses to farmers, and the lost fertilizers flowed into the water source, polluting the water source. The utilization rate of fertilizers is generally around 30%, so it is difficult to estimate the loss of fertilizers in the whole country, or even in the whole world. At the same time, fertilization is done blindly now, instead of requiring different fertilizers and nutri...
