Green Chinese onion planting method

Abstract

The invention discloses a green Chinese onion planting method. The planting method comprises the following steps: 1) carrying out land selection and soil preparation, 2) establishing a divided area; 3) carrying out backfilling with modified field soil; 4) carrying out transplanting, and 5) carrying out water and fertilizer management. A specific scheme of establishing a divided area in the step 2)comprises the follow steps: dividing a planting field into a planting area, and building a water-fertilizer channel in the middle position of the planting area along the length direction, wherein a region formed between the water-fertilizer channel and an isolation wall is a planting belt. A specific scheme of carrying out backfilling with the modified field soil in the step 3) comprises the follow steps: backfilling the planting belt with the modified field soil, and backfilling the water-fertilizer channel with sandy soil. According to the planting method provided by the invention, the planting field is divided into the planting area, the water-fertilizer channel is formed in the planting area, the planting belt is formed between the water-fertilizer channel and the isolation wall, theheight of the water-fertilizer channel is equal to the height of root systems, and the water-fertilizer channel is close to the root systems. Topdressing can be carried out in the water-fertilizer channel by using a fertilizer, so that water and fertilizer requirements of the green Chinese onion are met, and waterlogging can be prevented. Meanwhile, hilling can be carried out under the support ofthe isolation wall, so that hilling amount is reduced, and labor and time are saved.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, in particular to a method for planting green onions. Background technique [0002] Our country has a long history of scallion cultivation, and with the optimization and adjustment of the agricultural industrial structure, under the guidance of policies, scallion planting has developed to scale and quality, which not only improves the land utilization rate, but also forms many scallion varieties with local characteristics. It has become one of the main ways for farmers to increase their income. [0003] Scallions belong to the string-shaped fibrous root system, and the root branching and regeneration ability are weak. When the root system that has occurred is cut off, the broken root system cannot produce lateral roots. Therefore, in the cultivation and management of scallions, the damage to the root system should be minimized. It is often necessary to go deep into the root system, whi...

Problems solved by technology

However, when the scallion seedlings are 40cm high, topdressing is required. Although the document does not disclose the method of topdressing, it is not known that it is mainly root fertilization. Therefore, there is still the problem of damaging the root system of scallions.

In addition, scallions have strict requirements on water and fertilizer conditions at each growth stage, but the nutrients contained in pure soil are limited, and a large number of topdressing is required, which further aggravates the damage of topdressing to the root system.
