Method for preparing and applying special fertilizer for regional Chinese cabbages based on QUEFTS model

Abstract

The invention discloses a method for preparing and applying a special fertilizer for regional Chinese cabbages based on a QUEFTS model. The method for preparing and applying a special fertilizer for Chinese cabbages is light, simple, quantitative and reasonable and has a regionalization characteristic. In a complex Chinese cabbage fertilization system, growth environment and soil fertility of Chinese cabbage crops are evaluated through key parameters such as available yield, yield response and relative yield of Chinese cabbages. A nutrient demand proportion of nitrogen (N), phosphorus (P2O5) and potassium (K2O) of the special fertilizer for Chinese cabbages and a corresponding recommended fertilization method are rapidly and accurately provided. The method is a chemical fertilizer production and application reduction technology, can effectively improve yield of Chinese cabbage crops and a utilization rate of a fertilizer, reduces environmental pollution, improves soil fertility, is efficient, easy to implement and widely applicable, can protect the environment, and provides a technical guarantee for industrialized production of a specific bulk blend fertilizer and / or a compound fertilizer and / or a compound blend fertilizer special for Chinese cabbages with regional characteristics.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer production and balanced fertilization, in particular to a regionalized cabbage special fertilizer distribution and application method based on the QUEFTS model. Background technique [0002] Cabbage, a biennial herb, 40-60 cm high, usually glabrous throughout the plant, sometimes with a few spiny hairs on the midrib below the leaves. Native to northern China, it is a vegetable used in the genus Brassica of the family Brassicaceae, usually referring to Chinese cabbage; it also includes pakchoi and cabbage, a cultivar of cabbage, head cabbage, namely "cabbage" or "cabbage". Introduced to the south, it is cultivated in all parts of the north and south. In the nineteenth century, it was introduced to Japan, Europe and the United States. There are many kinds of Chinese cabbage. The Chinese cabbage in the north includes Jiaozhou Chinese cabbage in Shandong, Beijing Qingbai, Qingtian Maye C...

Problems solved by technology

Unreasonable fertilization not only causes waste of fertilizer resources and reduces the utilization rate of fertilizer, but also poses a threat to the ecological environment and affects the taste and quality of cabbage
