Problems solved by technology

[0003] Usually, the conventional fertilization of scallions is mostly based on nitrogen, phosphorus, and potassium fertilizers (especially the application of heavy nitrogen fertilizers), and the application of medium and micro fertilizers is underestimated, which has brought serious problems of partial application of chemical fertilizers and unbalanced supply and demand of nutrients in agricultural production. Fully meet the nutrients needed for the growth of green onions

Abstract

The invention provides a special fertilizer for green Chinese onions and a fertilizing method and aims to solve the deficiencies in the prior art. Through a large number of scientific experiments on studying green Chinese onion fertilizing technologies, the special fertilizer for the green Chinese onions is provided, so that high-quality green Chinese onions can be obtained and the green Chinese onions with light piquancy and better taste can be obtained. The special fertilizer comprises organic fertilizers, urea, diammonium phosphate, potassium nitrate, calcium fertilizers, magnesium fertilizers, sulfur fertilizers and silicon fertilizers. According to the invention, a best fertilization formula and a fertilization schedule used for fertilizing accurately can be obtained; the fertilizing method is reasonable, convenient to implement and good in effect.

Description

technical field [0001] The invention relates to a special fertilizer for scallions and a fertilization method, belonging to the technical field of agricultural cultivation. Background technique [0002] Scallion (Allium fistulosum L.) is a biennial herb of the Liliaceae Allium genus. It is commonly used as a vegetable in people's daily life. The fresh and tender leaves and pseudostems are rich in protein, Vc and minerals, and have strong bactericidal effect. Treat many diseases. Scallions are widely used for food and medicine because of their unique flavor and health effects. [0003] Usually, the conventional fertilization of scallions is mostly based on nitrogen, phosphorus, and potassium fertilizers (especially the application of heavy nitrogen fertilizers), and the application of medium and micro fertilizers is underestimated, which has brought serious problems of partial application of chemical fertilizers and unbalanced supply and demand of nutrients in agricultural p...
