Perilla frutescens residual film side hole sowing high-yield cultivation method for arid and semi-arid area

Abstract

The invention discloses a perilla frutescens residual film side hole sowing high-yield cultivation method for an arid and semi-arid area. The method comprises the following cultivation steps of preceding cropping, seed treatment, sowing, fertilization management, pest control and harvest, and compared with the prior art, by adopting the technical scheme, land moisture losses caused by spring drought can be reduced to the maximum extent, the sowing emergence rate and the transplanting survival rate of perilla frutescens in spring are guaranteed, and yield and income increase of the perilla frutescens in the later period is further guaranteed. According to the technology, through recycling of residual films in the last year, the advantages of resisting drought, saving water and increasing the ground temperature are achieved in the perilla frutescens planting area of the arid and semi-arid area, on the premise that the cost is not increased, limited rainfall can flow to furrows along mulching films (ridges) and is absorbed by perilla frutescens to the maximum extent, and a certain effect is achieved on prevention of early spring freeze injury.

Description

technical field [0001] The invention relates to the technical field of cultivation methods, in particular to a high-yield cultivation method for perilla perilla planting on the side of the residual film film in arid and semi-arid regions. Background technique [0002] Perilla is an annual herbaceous plant belonging to the Lamiaceae family. It is a plant used in traditional medicine, food, oil, vegetables, and spices. It is also the plant with the highest α-linolenic acid content (55% to 75%) in seed oil found so far. Widely distributed at an altitude of 260-2010m, latitude 20-34 ° area [1～3] . [0003] Gansu Province is one of the important production areas of perilla for oil in my country, with an annual planting area of ​​about 200,000 mu [3,4] . Longdong area is one of the main production areas of perilla cultivation in Gansu. Especially in recent years, with the rapid development of local perilla and edible oil industries, the planting area and comparative benefits o...

AI Technical Summary

Problems solved by technology

In Gansu Longdong perilla planting areas or domestic perilla planting areas with similar ecological conditions, the emergence of seedlings is poor due to drought and lack of rain in spring (April-May), so the result is often a large area of ​​production reduction or even failure to sow ; In addition, the early spring frost damage is frequent in Gansu Longdong area, and the damage caused is also relatively serious

[0006] However, due to the waxy surface of the perilla seed shell, its own germination rate is low. In addition, its main production area is located in the dry plateau of Longdong, Gansu. Large-scale production cuts
