Use method for potash fertilizer used for increasing crude fiber amount in brassica juncea (blocks)

Abstract

The invention discloses a use method for a potash fertilizer used for increasing the crude fiber amount in brassica juncea (blocks). The use method includes the following steps that previous crops are completely removed before brassica juncea soil preparation, and the ground is kept clean and smooth; an organic fertilizer is broadcast according to the proportion being 37500 kg / hm<2> and is then mixed with a phosphorus-nitrogen fertilizer according to the rule that smaller than or equal to 285 kg of a potassium sulfate fertilizer is broadcast per square hectometer, and the mixture is evenly broadcast to the ground; and deep ploughing of 20 cm is conducted, and the ground is raked to be uniform. Compared with the prior art, the use method has the following beneficial effects that compared with an existing traditional fertilizer application method, a nitrogen fertilizer can be saved by 38%, namely, 380 kg / hm<2>, and cost is saved by 450 yuan / hm<2>; the crude fiber amount in the brassica juncea (blocks) can be increased by 27.8%; and earnings are increased, and income can be increased by 5300 yuan / hm<2> for farmers.

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 increasing the amount of crude fiber in mustard (block) during mustard production. 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 traditi...

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
