Embodiment 1

[0019] Take the corn crop planted in a certain place as an example, and the planting area is one mu.

[0020] 1. Soil nutrient testing

[0021] 1) Sampling

[0022] Randomly select 20-100 points in the corn planting field to collect soil samples.

[0023] 2) Detection

[0024] The soil sample is dried, pre-treated, and soil nutrients are detected, mainly nitrogen, phosphorus, and potassium content, to obtain test values.

[0025] 2. Fertilizer formula

[0026] According to the nutrient test results of soil samples and related soil classification standards, the corn planting land is of medium soil quality, combined with the growth requirements of corn planting, the output of 100kg requires N, P, and K to be 2.8kg, 1.3kg, and 2.5kg respectively. The fertilizer formula The method is: the effective N, P, and K contents of the organic fertilizer are respectively N: 9 parts, P: 8 parts, and K: 8 parts by weight, and then the formula organic fertilizer is prepared according to th...

Embodiment 2

[0030] Take rice crops planted in a certain place as an example, and the planting area is one mu.

[0031] 1. Soil nutrient testing

[0032] According to embodiment 1.

[0033] 2. Fertilizer formula

[0034] According to the soil sample nutrient detection results and related soil classification standards, the paddy rice planting land is medium soil quality, and combined with the growth requirements of paddy rice planting, the fertilizer formula is: the effective N, P, and K contents of the organic fertilizer are respectively in parts by weight. , N: 8 parts, P: 9 parts, K: 8 parts, and then prepare the formula organic fertilizer according to the formula.

[0035] 3. Fertilization method

[0036] By adopting the above-mentioned formula fertilizer, 100 kg of fertilizer is applied to one mu of rice planting land, high yield can be achieved by one-time application of fertilizer, and the utilization rate of the bio-organic fertilizer reaches 85-98%.

Embodiment 3

[0038] Take tea crops planted in a certain place as an example, the planting area is one mu.

[0039] 1. Soil nutrient testing

[0040] According to embodiment 1.

[0041] 2. Fertilizer formula

[0042] According to the soil sample nutrient test results and related soil classification standards, the tea plantation land is medium soil quality, and combined with the growth needs of tea plantation, the fertilizer formula is: the effective N, P, and K contents of the organic fertilizer are respectively in proportions by weight. , N: 8 parts, P: 5 parts, K: 2 parts, and then prepare the formula organic fertilizer according to the formula.

[0043] 3. Fertilization method

[0044] Using the above-mentioned formula fertilizer, fertilizing 100 kg per mu of rice planting land, high yield can be achieved by one-time fertilization, and the utilization rate of the bio-organic fertilizer can reach 80-90%.

Abstract

The invention discloses a soil testing and formulated fertilization method. Since farmers in most areas in China mainly apply chemical fertilizers during cultivating the land and the quantity of the used farmyard manure is declined sharply, a large quantity of soil is caused to be hardened and the yield and the quality of crops are decreased. Through soil testing and formulation, under the situations that soil conditions are fully known and nutrients for which crops lack are compensated according to the growth rule of the crops, proper dosage and proportions of nitrogen, phosphate and potash fertilizers are put forwards, the nitrogen, phosphate and potash fertilizers are formulated into fertilizers which are directly applied to agricultural production and scientific fertilization is implemented by fully utilizing the growth rule of the crops. Compared with common fertilization methods, the soil testing and formulated fertilization method has the advantages that the fertilizers are applied to the crops in one season for one time, the labor and the time are saved, the utilization ratio of the fertilizers is improved, the soil fertility is cultivated, the nutrients are increased, the pollution is reduced, the ecological environment is improved and the yield and the quality of the crops are improved.

Description

technical field [0001] The invention relates to a method for soil testing and formula fertilization, in particular to a method for formula fertilization according to soil nutrients, and belongs to the technical field of agricultural fertilization. Background technique [0002] The fertilization habits of the vast majority of farmers in most areas of our country are to use farm manure and chemical fertilizers. So far, farmers in most areas of our country still mainly rely on chemical fertilizers for farming and fertilization, and the amount of farm manure has dropped sharply. It is precisely because some farmers use excessive chemical fertilizers that the soil is damaged to varying degrees, resulting in irregular soil nutrient content in different regions, and causing a large amount of soil compaction, and the yield and quality of crops begin to decline. Therefore, the soil testing formula Fertilization is particularly important and needs to be done for a long time to improve...
