Embodiment 1

[0025] Embodiment 1: Soil testing fertilization carried out with soil available potassium content less than or equal to 130mg / kg

[0026] 1) Soil nutrient testing:

[0027] ① Sampling: Plant rhubarb after the potatoes are harvested, select a rhubarb field with an area of ​​2-10 mu, follow the S-shaped route, follow the principles of "random", "equal", and "multi-point mixing" Sampling points 15-20 sampling points, sampling depth 0-20cm, according to the quartering method to retain 1kg of samples, so that the sampling site is consistent with the fertilization site;

[0028] ② Detection: Dry the soil samples, carry out pre-testing treatment, detect soil pH, organic matter, alkali-hydrolyzed nitrogen, available phosphorus, and available potassium. The determination of available phosphorus adopts alkaline solution diffusion method, the determination of available phosphorus adopts sodium bicarbonate to extract molybdenum antimony anti-colorimetric method, and the determination of ...

Embodiment 2

[0038] Embodiment 2: soil available potassium content is less than or equal to: the soil testing fertilization that 130mg / kg carries out

[0039] 1) Soil nutrient testing:

[0040] ① Sampling: Plant rhubarb after the potatoes are harvested, select a rhubarb field with an area of ​​2-10 mu, follow the S-shaped route, follow the principles of "random", "equal", and "multi-point mixing" Sampling points 15-20 sampling points, sampling depth 0-20cm, according to the quartering method to retain 1kg of samples, so that the sampling site is consistent with the fertilization site;

[0041] ② Detection: Dry the soil samples, carry out pre-testing treatment, detect soil pH, organic matter, alkali-hydrolyzed nitrogen, available phosphorus, and available potassium. The determination of available phosphorus adopts alkaline solution diffusion method, the determination of available phosphorus adopts sodium bicarbonate to extract molybdenum antimony anti-colorimetric method, and the determina...

Abstract

The invention provides a soil measurement and fertilizer application method of rheum officinale. The method is implemented through three steps of soil nutrition detection, fertilizer application amount calculation and fertilizer application; the matching of N, P and K is adjusted scientifically and reasonably, and the soil nutrition proportion is coordinated, so that the fertilizer utilization rate is raised by over 4% on average, the soil nutrition loss, unbalance, non-point source pollution and soil acidification can be avoided, the yield of rheum officinale is raised, and the soil measurement and fertilizer application method is particularly suitable for fertilizer application to a rheum officinale field.

Description

technical field [0001] The invention relates to a soil testing and fertilization method, in particular to a rhubarb soil testing and fertilization method. 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 rhubarb fertilization, most farmers fertilize according to experienc...
