Slow release compound fertilizer special for turnip

Abstract

The invention relates to a fertilizer special for turnip, in particular to a slow release compound fertilizer special for turnip in a stagger-season vegetable producing area of Bashang plateau in the northwest of Hebei Province. The slow release compound fertilizer consists of active ingredients and auxiliary materials, wherein the active ingredients comprise 16 to 20 weight parts of nitrogen, 8 to 12 weight parts of phosphorous, 12 to 15 weight parts of potassium, 0.1 to 0.4 weight part of boron and an inhibitor in an adding amount which is 1 to 4 weight percent of nitrogen; and the inhibitor is a nitrification inhibitor and a urease inhibitor, the urease inhibitor is hydroquinone or N-(n-butyl)thiophosphoric triamide, and the nitrification inhibitor is dicyandiamide, 3,4-dimethyl pyrazole phosphate, 3,5-dimethyl pyrazole or 3,5-dimethyl pyrazole phosphate. The fertilizer is applied at one time before the turnip is planted, and the fertilizer can meet the requirement of the turnip on nutrients in the whole growth and development process, the turnip has dark green leaves, the yield is high and the nutrient utilization rate is high.

Description

technical field [0001] The invention relates to a special fertilizer for radishes, in particular to a special long-acting compound fertilizer for radishes suitable for producing areas of seasonal vegetables in Bashang, Northwest Hebei. Background technique [0002] The unique climatic characteristics of the Bashang area in Northwest Hebei Province give cool vegetables a unique development space. The area has sufficient sunlight and a large temperature difference between day and night. The large white radishes that are marketed in July and August have large fleshy roots, correct shape, smooth skin, good taste and eating quality. After processing and pickling, they are favored by foreign merchants such as South Korea, Japan, and Singapore. , and this period coincides with the off-season when white radish is on the market in other parts of my country, so the economic benefits are very considerable. Especially in recent years, with the introduction and promotion of some fine var...

AI Technical Summary

Problems solved by technology

[0003] However, due to the lack of special fertilizers on the market that are suitable for the nutrient requirements of radishes in cold and cold climates, and the general lack of scientific cultivation and management knowledge among vegetable farmers, blind fertilization and excessive fertilization are very common in production. Nutrient imbalance and radish physiological diseases are becoming more and more serious, which have seriously restricted the development of the local radish industry

Moreover, the waste of nutrient resources caused by unbalanced application of fertilizers, and the environmental pollution caused by nitrogen volatilization and leaching loss have also become important factors that limit the sustainable development of local agriculture.
