Method for planting non-heading Chinese cabbages under condition of reduced application of nitrogen fertilizer

Abstract

The invention discloses a method for planting non-heading Chinese cabbages under the condition of reduced application of a nitrogen fertilizer. The method for planting the non-heading Chinese cabbages under the condition of reduced application of the nitrogen fertilizer comprises the following steps of (1) taking soil of a field planting plot, and measuring basic physicochemical properties of the soil; (2) determining the appropriate fertilization amount of the non-heading Chinese cabbages according to a simulation equation; (3) raising seedlings of the non-heading Chinese cabbages in advance, performing field planting after 23-28 days, using a nitrogen-phosphorus-potassium fertilizer as a base fertilizer for one-time broadcast application, reducing the nitrogen element consumption by 20-30% on the basis of the appropriate fertilizer application amount, and meanwhile, applying a biological organic fertilizer-'Nangbowang' composite microbial fertilizer; and (4) spraying a biostimulant seaweed essence on leaf surfaces once every 9-11 days according to the seedling recovery condition. According to the method for planting the non-heading Chinese cabbages under the condition of reduced application of the nitrogen fertilizer, on the basis of reducing application of the nitrogen fertilizer, the biostimulant and the biological organic fertilizer are applied to open field production of the non-heading Chinese cabbages, the effect of co-application of the biostimulant and the biological organic fertilizer is remarkably better than that of single application of the biostimulant and the biological organic fertilizer, growth of the non-heading Chinese cabbages can be remarkably promoted, the photosynthetic characteristic is improved, the yield is increased, and the nitrate content is reduced.

Description

technical field [0001] The invention discloses a method for planting non-heading Chinese cabbage under the condition of reduced application of nitrogen fertilizer, and belongs to the technical field of planting non-heading Chinese cabbage. Background technique [0002] Vegetables are the second largest crop after grain in China's planting industry, and the vegetable industry is one of the important pillar industries in China's agriculture and rural economy. It is the main line of the development of the vegetable industry to make every effort to promote the stable production of vegetables, improve the quality of vegetables, ensure the balance between supply and demand in the market, and increase farmers' income. In recent years, the vegetable industry has developed rapidly and a good supply market has been formed. However, there are still problems such as large amount of chemical fertilizer application, single variety, and unbalanced application amount in production, resultin...
