Problems solved by technology

[0004] At present, sugarcane production still relies on the application of traditional fertilizers, including general NPK monomer fertilizers, or ordinary ternary compound fertilizers. The utilization rate of fertilizers is low. Generally, nitrogen fertilizers only need 30%, and phosphorus fertilizers are 15% to 20% (when produced ), potassium fertilizer is 35%

Embodiment 1

[0029] From January, 2012 to December, 2012, in Heji Town, Binyang County, Guangxi, the preparation method and field application technology of sugarcane special-purpose whole element compound fertilizer of the present invention were adopted, and the steps were as follows:

[0030] (1) Determination and analysis of the physical and chemical properties (mainly chemical properties) of the target sugarcane field soil:

[0031] a. Location: Heji Town, Binyang County, Guangxi;

[0032] b. Area: 500 mu;

[0033] c. Previous crop: sugarcane;

[0034] d. Soil: brick red soil red soil. Before sugarcane planting, the 0-30cm plow layer soil was collected for nutrient analysis. The physical and chemical properties of the soil are: pH4.94, organic matter 1.80%, total nitrogen 1.54mg / kg, available nitrogen (N) 63.11mg / kg, total phosphorus 0.85mg / kg , available phosphorus (P 2 o 5 ) 21.02mg / kg, total potassium 3.31mg / kg, available potassium (K 2 O) 140.37mg / kg, effective magnesium 16.15...

Embodiment 2

[0049] A kind of preparation method of whole element compound fertilizer special for sugarcane, the steps are as follows:

[0050] (1) Granulation and drying of P, K and medium and trace element fertilizers:

[0051] Produce P-containing materials by disc method by crushing P-containing materials 2 o 5 (15% to 25%) granular fertilizer, the appearance of the product is small balls, the size is 2.00mm to 4.00mm, dried to a moisture content of ≤ 2%;

[0052] It is made of various materials containing K and nutrients such as Ca, Mg, Si, B, Mo, Zn, etc. by crushing and using disc method to make K 2 O(20%~30%), Ca(4%~6%), Mg(1%~3%), Si(2%~6%), B(0.10%~0.15%), Mo(0.05%~ 0.10%), Zn (0.2% ~ 0.4%) granular fertilizer, the appearance of the product is small balls, the size is 2.00mm ~ 4.00mm in particle size, and dried until the moisture content is ≤ 2%.

[0053] (2) Blending and finished products:

[0054] Mix ready-made coated N fertilizer granules with P, K and medium and trace e...

Abstract

The invention discloses a preparation method and a field using technology of a special all-element compound fertilizer for sugarcane. The preparation method and the field using technology comprise the following steps: (1), preparing a high-yield cultivation nutrient formula for the sugarcane; (2), preparing the special all-element compound fertilizer for the sugarcane; (3), applying the compound fertilizer in a field; and (4), topdressing. The preparation method and the field using technology of the special all-element compound fertilizer for sugarcane are strong in specificity and capable of achieving comprehensive benefits of increasing the yield, saving the fertilizer and saving the labor.

Description

technical field [0001] The invention relates to a sugarcane cultivation technique, in particular to a production method and a field application technique of a whole-element compound fertilizer special for sugarcane. Background technique [0002] Sugarcane (Sugarcane) is the main sugar crop in my country. It is widely planted in tropical and subtropical regions of China and plays an irreplaceable role in promoting economic development and social stability in production areas. As a C4 crop, sugarcane has the characteristics of long growth period, high yield, and high nutrient consumption. It is an economic crop that requires a large amount of fertilizer. According to statistics, each ton of sugarcane needs to absorb 1.5-2 kg of nitrogen (N) and phosphorus (P) from the soil. 2 o 5 )1~1.5kg, Potassium (K 2 O) 2~2.5kg, fertilizer has become the most important means of production in sugarcane agricultural production. However, for a long time, the fertilization of sugarcane are...
