Application method of potassium fertilizer for improving protein mass in brassica juncea (root tuber)

Abstract

The invention discloses an application method of a potassium fertilizer for improving protein mass in brassica juncea (root tuber). The method includes the following steps: 1) before soil preparation of the brassica juncea, removing previous crops completely to maintain the soil to be clean and tidy; 2) spread-applying an organic fertilizer by 37500 kg / hm<2>, and mixing a potassium sulfate fertilizer, being not more than 225 kg / hm<2>, with a phosphorus nitrogen fertilizer and uniformly spread-applying the mixed fertilizer on soil; 3) deeply-ploughing the soil by 20 cm and uniformly harrowing the soil. Compared with the prior art, the method is advantaged in that: 1) compared with the conventional fertilizer application methods, the method saves nitrogen fertilizer by 35%, namely, 350 kg / hm<2>, so that cost is saved by 420 yuan / hm<2>; 2) protein mass in the brassica juncea (root tuber) is increased to 3.26%; and 3) the method increases incoming by 5000 yuan / hm<2>.

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 protein content in mustard greens (blocks) during the mustard greens 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 ...

AI Technical Summary

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, the lack of advanced cultivation technology, unreasonable fertilization, low yield, and unsatisfactory benefits; the quality cannot be effectively controlled, affecting the quality and sales

It directly restricts the stable and healthy development of mustard production
