Potassium fertilizer applying method for improving leaf mustard quality

Abstract

The invention discloses a potassium fertilizer applying method for improving leaf mustard quality. The method comprises the following steps: removing previous crops before preparing the soil for leaf mustard, so as to keep the land clean and flat; applying an organic fertilizer based on 37,500 kg / hm<2>; uniformly spreading the mixture of K2O5 and a nitrogen phosphorus fertilizer to the land, wherein 4.5 kg of K2O5 is applied to produce every 1,000 kg of leaf mustard; deeply ploughing 20 cm, and uniformly raking. Compared with the prior art, the method has the advantages that 1), as compared with an original traditional fertilizer applying method, 50% of nitrogenous fertilizer, namely, 400 kg / hm<2> of nitrogenous fertilizer, can be saved, and 615 Yuan / hm<2> of cost can be saved; 2) the leaf mustard quality can be improved: 0.008% of sinapic acid can be increased, 1.004% of nitrite can be deceased, and 0.008% of dietary fiber can be increased; 3) the benefit can be increased, and 5500 Yuan / hm<2> of income can be increased for a farmer.

Description

technical field [0001] The invention belongs to the technical field of vegetable production, and in particular relates to a method for using potassium fertilizer for improving the quality of mustard in the mustard production process. Background technique [0002] Mustard greens, commonly known as mustard lumps. It has been cultivated for hundreds of years in western Henan and other places. In particular, mustard processing methods and techniques have been passed down among the people for a long time, and have been listed in the Zhengzhou Intangible Cultural Heritage List. Due to its special taste and flavor, it has always been one of the main dishes necessary for home life in many areas. However, because mustard is a vegetable grown in local areas, the proportion of the area in vegetable production is very small for the whole country. Few people have conducted in-depth and detailed research on this, so the cultivation technology is still stuck in the traditional "small far...

Problems solved by technology

However, because mustard is a vegetable grown in local areas, the area accounts for a small proportion of vegetable production in the whole country.

Few people have conducted in-depth and detailed research on this, so the cultivation technology is still stuck in the traditional "small farmers" planting habits, lack of advanced cultivation technology, unreasonable fertilization, low yield, unsatisfactory benefits; quality cannot be effectively controlled, affecting quality and sales

It directly restricts the stable and healthy development of mustard production
