Problems solved by technology

[0003] A large amount of nitrogen fertilizers are often used in the existing Chinese cabbage cultivation process. Over time, serious groundwater nitrate pollution and soil nitrate nitrogen accumulation are caused. At the same time, it also affects the availability of phosphorus and potassium in the soil, resulting in soil fertility and the quality of cultivated Chinese cabbage. keep falling

Abstract

The invention belongs to the technical field of vegetable cultivation, in particular to a fertilization method for flowering cabbage. The method comprises the following steps: mixing a base fertilizerwith soil uniformly by way of deep ploughing and harrowing; applying a biogas slurry fertilizer or a high nitrogen quick-acting fertilizer when the first main leaf of the flowering cabbage is unfolded; applying the biogas slurry fertilizer or the high nitrogen quick-acting fertilizer or a compound water soluble fertilizer when the third main leaf of the flowering cabbage is unfolded; adjusting the fertilizing frequency of the biogas slurry fertilizer or the high nitrogen quick-acting fertilizer or the compound water soluble fertilizer when buds of the flowering cabbage appear; and spraying asodium molybdate solution or a manganese chloride solution a week before harvesting the flowering cabbage. By reducing application of the nitrogen fertilizer, an organic fertilizer and biogas manure are combined in water and fertilizer integrated fertilization mode, so that the quality of the flowering cabbage is improved, and nitrate and nitric nitrogen pollution in soil is reduced.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, in particular to a method for fertilizing Chinese cabbage. Background technique [0002] Caixin, also known as cabbage sprouts, is a Brassica genus in the family Brassicaceae. It is a one-year-old or biennial herb with comprehensive nutrients, including niacin, carotene, vitamin A, vitamin C, vitamin E, and trace elements such as calcium, phosphorus, and potassium. . Caixin is suitable for sowing in warm areas in the south. It is one of the specialty vegetables in southern my country. It can be sown all year round. It is the most widely eaten vegetable in the Jiangnan area. After the 1990s, with the rapid development of social economy and frequent personnel exchanges, people from the north and the south gradually infiltrated each other, and their eating habits merged with each other. Coupled with the development of greenhouse vegetable cultivation technology, the demand for cabbage...
