Method for reducing continuous cropping obstacles of hot peppers in arched shed by associated combined biochar

Abstract

The invention belongs to the technical field of planting methods, and provides a method for reducing continuous cropping obstacles of hot peppers in an arched shed through associated combined biochar. The method comprises the following steps: spreading a base fertilizer in an arched shed, and ploughing for at least one time; preparing ridges, spreading biochar on the ridges, and uniformly plowing and raking to form a root growth soil layer; covering the root growth soil layer with a soil layer; performing disinfection and sterilization operation; pepper transplanting; when the peppers grow to have at least 10 true leaves, oat seeds subjected to activating treatment are scattered between the pepper rows and on the two sides of the ridges; and performing daily management. By applying biochar and associated oats, pepper continuous cropping obstacles are effectively reduced, the threat of soil-borne diseases and insect pests is relieved, and yield conservation and yield increase of arched shed continuous cropping peppers are achieved. Meanwhile, it is accidentally found that under the combined action of the biochar and the oat accompanying, the Fe element content in the pepper fruits is remarkably increased, and the method is a potential high-iron-content pepper planting method.

Description

technical field [0001] The invention belongs to the technical field of planting methods, and in particular relates to a method for reducing the continuous cropping obstacles of pepper in arched sheds with associated combined biochar. Background technique [0002] Capsicum frutescens (Capsicum frutescens) is a plant of the Solanaceae Capsicum genus. It is rich in polyphenols, capsaicin, ascorbic acid and other chemical substances, and has functional properties such as antibacterial, antioxidant, and weight control. 20 times. Pepper is one of the top ten vegetables in the world. At present, the annual planting area of ​​pepper in China has exceeded 1.8 million hectares, accounting for 8% to 10% of the total vegetable planting area in the world. [0003] In recent years, with the development of large-scale and procedural facilities, chemical fertilizers have been gradually used to increase pepper production. At the same time, pepper planting bases are more concentrated and con...

Problems solved by technology

[0008] Based on this, the present invention provides a method for reducing the obstacle of pepper continuous cropping in shed with associated biochar, so as to solve the technical problems in the prior art that the morbidity of pepper is high and the yield is obviously reduced in the shed of pepper that has been planted continuously for many years
