Problems solved by technology

[0002] At present, my country's agricultural fertilization, for many years, has always had problems such as irrational use of chemical fertilizers and unbalanced nutrients, which not only cause low nutrient utilization, waste of resources, increase in agricultural input costs, and decline in the quality of agricultural products, but also cause deterioration of soil properties and ecological environment pollution. And other issues

Embodiment 1

[0025] Embodiment 1: Soil testing fertilization carried out with soil available potassium content less than or equal to 90mg / kg

[0026] 1) Soil nutrient testing:

[0027] ① Sampling: Select a mung bean field with an area of ​​4-10 mu, follow the S-shaped route, follow the principles of "random", "equal volume" and "multi-point mixing", and use 16-25 sampling points for each sample. point, the sampling depth is 0-20cm, and a 1kg sample is taken according to the quartering method, and the questionnaire is filled out, so that the sampling site is consistent with the fertilization site;

[0028] ② Detection: Dry the soil samples, perform pre-testing treatment, and use conventional analysis methods to detect soil pH, organic matter, alkaline nitrogen, available phosphorus, and available potassium. The pH of the soil is measured by the acid meter method, and the organic matter is measured by the potassium dichromate method. , the determination of alkaline hydrolysis nitrogen adopt...

Embodiment 2

[0037] Embodiment 2: Soil testing fertilization carried out with soil available potassium content greater than 90mg / kg

[0038] 1) Soil nutrient testing:

[0039] ① Sampling: Select a mung bean field with an area of ​​4-10 mu, follow the S-shaped route, follow the principles of "random", "equal volume" and "multi-point mixing", and use 16-25 sampling points for each sample. point, the sampling depth is 0-20cm, and a 1kg sample is taken according to the quartering method, and the questionnaire is filled out, so that the sampling site is consistent with the fertilization site;

[0040] ② Detection: Dry the soil samples, perform pre-testing treatment, and use conventional analysis methods to detect soil pH, organic matter, alkaline nitrogen, available phosphorus, and available potassium. The pH of the soil is measured by the acid meter method, and the organic matter is measured by the potassium dichromate method. , the determination of alkaline hydrolysis nitrogen adopts alkalin...

Abstract

A mung bean, soil detecting and fertilizing method comprises the three steps of soil nutrient detection, fertilizing amount calculation and fertilizing, the proportion of N, P, K is scientifically and reasonably adjusted, and the soil nutrient proportion is coordinated. Thus, the fertilizer utilization rate is improved by more than 4%, the loss and imbalance of soil nutrients, non-point source pollution and soil acidification are not caused, the mung bean yield is improved, and the mung bean, soil detecting and fertilizing method is particularly suitable for fertilization in mung bean land.

Description

technical field [0001] The invention relates to the technical field of soil testing and fertilization for crop planting, in particular to a soil testing and fertilization method for mung bean planting. Background technique [0002] At present, my country's agricultural fertilization, for many years, has always had problems such as irrational use of chemical fertilizers and unbalanced nutrients, which not only cause low nutrient utilization, waste of resources, increase in agricultural input costs, and decline in the quality of agricultural products, but also cause deterioration of soil properties and ecological environment pollution. And other issues. The seasonal utilization rate of grain crop nutrients in my country is 30% to 35% for nitrogen fertilizer, 15% to 20% for phosphorus fertilizer, and 35% to 50% for potassium fertilizer, which is 15 to 20 percentage points lower than that of developed countries, and it is gradually decreasing. Especially for mung bean fertilizati...
