Double-cropping planting method for tobacco plants and autumn peas

Abstract

The invention belongs to the technical field of crop-rotation planting of tobacco plants and discloses a double-cropping planting method for tobacco plants and autumn peas. The method comprises the steps: tobacco plant-autumn pea crops-for-rotation link: carrying out land preparation, and carrying out basal fertilizer application; autumn pea planting: carrying out sowing, carrying out fertilizer and water management, and carrying out harvesting; autumn pea-tobacco plant crops-for-rotation link: carrying out land preparation, carrying out ridge forming, carrying out basal fertilizer application, and carrying out mulching; and tobacco plant planting: carrying out seedling raising, carrying out transplanting, carrying out field management, and carrying out mature picking and curing. Accordingto the method, the problem on tobacco field soil obstacle caused by the existing tobacco plant planting single-cropping continuous-cropping mode can be effectively solved, soil nutrients are balanced, root system development is promoted, accumulation of harmful substances and plant diseases and insect pests are reduced, the yield and quality of tobacco leaves and comprehensive economic results ofa tobacco field are improved. Shown by experiments, by the method, organic matters of soil can be increased by 10%-20%, the structure of an arable layer is improved obviously, the incidence rate of diseases is lowered by 55%, the first-class tobacco ratio of the tobacco leaves is increased by 5%-7%, the chemical ingredient coordination and sensory evaluation score of the tobacco leaves are improved obviously, and the comprehensive economic results of farmers are increased by 15%-20%.

Description

technical field [0001] The invention belongs to the technical field of tobacco rotation planting, and in particular relates to a tobacco-autumn pea planting method twice a year. Background technique [0002] At present, the closest existing technology: the tobacco planting model is to achieve the layout and distribution of tobacco and other food crops or economic crop planting structures under certain natural resources and socio-economic conditions, so as to achieve the improvement and sustainability of crop product quality. Development, a comprehensive technical system that combines land use and land cultivation, including planting arrangements, farming methods and supporting technical measures, is one of the key links in the tobacco cultivation and farming system. Adopting a reasonable farming pattern in tobacco leaf production can not only reduce the occurrence of diseases and insect pests, coordinate the supply of soil nutrients, improve the soil ecological environment, ...

AI Technical Summary

Problems solved by technology

There are disadvantages in the single-cropping and continuous-cropping mode of tobacco: perennial continuous cropping leads to imbalance of soil nutrients in tobacco fields, accumulation of harmful substances, deterioration of physical structure, aggravation of tobacco pests and diseases, decline in tobacco leaf yield and quality, and reduction in economic benefits, etc.

There are disadvantages in the two-crop model of Tobacco-Piperia glabra: As green manure, P.

The tobacco-garlic (cabbage) cropping pattern has disadvantages: vegetable planting input costs are high, vegetable prices fluctuate greatly, there is a risk of loss, and vegetable planting cannot be applied on a large scale

The two-year four-cropping crop rotation model has disadvantages: the crop rotation cycle is longer, and the annual average economic benefit is lower than that of tobacco continuous cropping, which also leads to the limited application area of ​​this model, and it is only used when the continuous cropping tobacco field is unsustainable

[0005] (1) Perennial continuous cropping in the existing tobacco single-cropping mode leads to soil quality decline, soil nutrient imbalance in tobacco fields, accumulation of harmful substances, deterioration of physical structure, aggravation of tobacco pests and diseases, decline in tobacco leaf yield and quality, and reduction in comprehensive economic benefits of tobacco fields

[0006] (2) In the existing tobacco-Piperia glabrata double-cropping pattern in one year, there is Pipsia glabrata as a green manure, which can improve the soil, but it cannot produce direct economic benefits, and the enthusiasm of tobacco growers is low

[0007] (3) The existing tobacco-garlic (cabbage) cropping mode twice a year has high vegetable planting input costs, large fluctuations in vegetable prices, and risk of loss, and vegetable planting cannot be used on a large scale

[0008] (4) The existing two-year four-cropping crop rotation model has a longer crop rotation period, and the annual average economic benefit is lower than that of tobacco continuous cropping. This also leads to a limited application area of ​​this model, and it is only used when continuous cropping tobacco fields are unsustainable

[0010] Significance of solving the above technical problems: To establish a modern and efficient planting mode that is suitable for large-scale tobacco fields in southwest tobacco areas, with tobacco as the mainstay and combined with autumn peas. It will be of great significance for the stable development of tobacco leaf production in southwest tobacco areas and the continuous increase of tobacco farmers’ income
