Protecting soil ecology and improving crop quality is an important part of current agricultural cultivation. We know that the nutrients and water needed for crops are extracted from the soil, so good soil ecology is an important basis for improving crop quality. At present, in the orchard planting, the soil nutrient is lacking, and the phenomenon of nutrient imbalance is very common. To solve the problem of soil nutrient, the soil nutrient tester can be used to test the soil, and the soil nutrient management of the orchard in summer and autumn is emphasized.
Taking citrus cultivation as an example, citrus has different needs for soil nutrient content and species in different growth stages. For example, N and P have the highest demand during the flowering period of sucrose orange, and K has the highest demand during flowering to young fruit. Ca and Cu were the lowest at the flowering stage, then gradually increased, and reached the highest at maturity. The demand for Mg, Zn, Fe, Mn and B was slightly lower at the flowering stage, and the demand during each growth period was relatively stable. 1 ton of sugar orange needs 12.95-15.11kg of pure nitrogen, 7.77-9.1kg of pure phosphorus and 12.95-15.11kg of pure potassium. Summer and autumn are the key period for citrus cultivation. During this period, it is necessary to focus on the nutritional needs of each stage of citrus growth and to carry out reasonable fertilization. The application of soil nutrient analyzer in soil nutrient management in summer and autumn of citrus can provide scientific guiding ideas for rational fertilization.
The soil nutrient analyzer is an important soil nutrient detection instrument. In the orchard management, the instrument can be used to determine the nutrient content of nitrogen, phosphorus and potassium in the orchard soil, and the nutrient profit and loss in the orchard can be found in time, and the fertilization operation can be carried out reasonably. Improve the soil fertility of the orchard. Not only that, the application of the instrument can effectively reduce the acidification and compaction of the soil, save the cost of agricultural production, create a good living environment for the citrus roots, and achieve the goal of high quality and high yield, and obtain the best benefits.
