Using method of nitrogen fertilizer for improving VC content in mustard (blocks)

Abstract

The invention discloses a using method of a nitrogen fertilizer for improving the VC content in mustards (blocks). The using method comprises the following steps that before mustard land preparation, previous crops are firstly cleaned, and land is kept clean and flat; 37500 kg / hm2 of organic fertilizer is applied, then 103.5-390 kg / hm2 of urea and a phosphorus and potassium fertilizer are mixed and are evenly scattered on the land; deep ploughing of 20 cm is performed, and even harrowing is performed. Compared with the prior art, the using method has the following advantages that 1, the technology can save the nitrogen fertilizer by 30%, namely 260 kg / hm2 than original traditional fertilization methods; the cost can be saved by 380 yuan / hm2; the VC content in mustards (blocks) can be improved by 10.5%; the income is increased, and the income of farmers can be increased by 4000 yuan / hm2.

Description

technical field [0001] The invention belongs to the technical field of vegetable production, and in particular relates to a method for using nitrogen fertilizer for increasing the VC content in mustard (block) 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...

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
