Problems solved by technology

[0002] At present, in my country's agricultural fertilization, especially corn fertilization, most farmers apply fertilizer according to experience without knowing the soil nutrient status and the fertilizer requirement of corn. In this way, there are more nitrogen and phosphorus fertilizers, no potassium fertilizer or less application The traditional habit of potassium fertilizer follows the customary fertilization mode. This fertilization mode is mainly divided into one fertilization, and nitrogen fertilizer is topdressed once from the seedling stage to the small trumpet stage, mainly urea, and ammonium bicarbonate is also applied. The application ratio of nitrogen, phosphorus, and potassium fertilizers Uncoordinated and inappropriate methods lead to loss of soil nutrients, imbalance, non-point source pollution, and soil acidification is getting worse

Embodiment 1

[0022] ①Soil nutrient detection:

[0023] 1) Sampling: After the corn is harvested, select a corn field with a plot area of ​​1.5-10 acres, along the S-shaped route, according to the principles of "random", "equal amount", and "multi-point mixing", sampling for each sample Point 15-20 sample points, sampling depth 0-20cm, according to the quarter method to save 1kg sample, GPS positioning the longitude and latitude of the sampling, fill in the questionnaire, make sure that the sampling location is consistent with the fertilization location;

[0024] 2) Testing: Dry the soil sample, perform pre-treatment, and use conventional analysis methods to detect soil pH, organic matter, alkali hydrolyzed nitrogen, available phosphorus and available potassium. The soil pH is measured by the pH meter method, and the organic matter is measured by the potassium dichromate method. , The alkaline hydrolysis nitrogen is determined by the alkaline hydrolysis diffusion method, the effective phosphorus...

Abstract

The invention relates to a maize soil testing fertilization method which is realized by three steps of soil nutrient detection, fertilizing amount calculation and fertilization. The proportion of N, P and K is scientifically and reasonably adjusted, and the soil nutrient proportion is coordinated, therefore, the invention improves the utilization ratio of fertilizer by more than 3 percent on average, does not cause soil nutrient loss and unbalance, diffused pollution and soil acidification, improves the maize yield and is particularly suitable for the fertilization of a maize field.

Description

Technical field: [0001] The invention relates to a soil testing fertilization method, in particular to a soil testing fertilization method for corn. Background technique: [0002] At present, in our country’s agricultural fertilization, especially corn fertilization, most farmers apply fertilization based on their experience without knowing the soil nutrient status and the law of fertilizer requirements of corn. In this way, there is more nitrogen and phosphorus fertilizer, no potassium or less fertilizer. The traditional habit of potash fertilizer is to follow the customary fertilization mode. This fertilization mode is mainly to apply fertilizer at once, topdressing nitrogen fertilizer once from the seedling stage to the small bell mouth stage, with urea as the mainstay, and the application ratio of ammonium bicarbonate and nitrogen, phosphorus and potassium. Uncoordinated and improper methods have caused soil nutrient loss, imbalance, non-point source pollution, and soil acidi...
