Soil testing and formulated fertilization method for use in environment-friendly cultivation of cucumber

Abstract

The invention discloses a soil testing and formulated fertilization method for use in environment-friendly cultivation of cucumber. The method comprises the following steps: detecting the soil of a place of origin as well as the contents of organic matters, alkali-hydrolyzable nitrogen, rapidly available phosphorus and rapidly available potassium contained in organic fertilizers; detecting target yield, reasonably selecting the utilization ratio of each nutrient in soil during seasonable production of cucumber, and selecting the utilization ratio of each nutrient in applied fertilizers during seasonable production of cucumber; determining the absorption of each known major nutrient by cucumber; selecting fertilizers according to the pH value of soil and the fertilizer needing characteristics of crops; calculating and determining the needed amounts of a main fertilizer and an auxiliary fertilizer; determining a formulated fertilization scheme; and determining a fertilization method. The calculation of the formulated fertilization amount is more accurate and more reliable than that in the prior art; by considering the types and characteristics of varieties, the target yield is more consistent with practical situations; the nutrient amount of soil is calculated accurately and reliably; the fertilizers are selected under the full consideration of the soil acidity and alkalinity as well as the requirement of cucumber on fertilizer characteristics; by adopting the fertilization method, labor force is reduced, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a soil testing and formulated fertilization method for cucumber green cultivation. Background technique [0002] Large-scale vegetable production is an inevitable trend of social and economic development. The research and application of soil testing and formulated fertilization technology is also an inevitable need for the development of social science. In agricultural production, the application of soil testing and formulated fertilization technology is being widely promoted; the research on soil testing and formulated fertilization technology is also being carried out in depth. [0003] The technology of soil testing and formula fertilization of cucumber is also under continuous research and exploration. Prior art at first determines that every 1000 kilograms of cucumbers are produced to the demand of three major nutrients such as nitrogen, phosphorus pe...

AI Technical Summary

Problems solved by technology

[0006] One is that it only addresses the supply of nutrients by applying fertilizers, ignoring the selection of soil pH on the type of fertilizer and the requirements of crops on the characteristics of fertilizers

[0007] Second, only the application amount of organic fertilizer is introduced, and what type of organic fertilizer should be applied is not specified

[0008] The third is that in the calculation, the utilization coefficient of the soil's own nutrients in the production of cucumbers in the current season and the utilization rate of the fertilizer applied in the production of cucumbers in the current season are not considered.

[0009] Fourth, there is no introduction to the calculation method of formula fertilizer

[0010] Fifth, there is a lack of consideration of various relevant data acquisition factors

[0012] One is still according to the traditional fertilization method combining base fertilizer and top dressing, which is not conducive to large-scale cultivation

[0013] Second, the number of soil plowing after fertilization is not introduced, which is not conducive to ensuring the survival rate of transplanting

[0014] The third is whether watering treatment is required after fertilization is not introduced, which is not conducive to the improvement of fertilizer utilization in the current season
