Problems solved by technology

In Hunan, fritillary fritillary is the main cultivar. It is generally planted in autumn and harvested in spring. It is planted in a single season, and the idle time in summer is too long. It is rotated with other crops. The economic benefits are not good, there are conflicts in time, and the technology is not mature.

Embodiment 1

[0031] A method for planting tobacco and Fritillaria in rotation, comprising the following steps:

[0032] (1) Base fertilizer for site preparation: Plow the soil of the tobacco field deeply by 20-30cm, combine two shallow trenches with a depth of 5cm at the bottom of each ridge for site preparation, apply tobacco-specific base fertilizer by strip method, and apply tobacco-specific base fertilizer 50-50 cm per acre 55kg, total nutrient ≥ 30% in the special base fertilizer for tobacco, N:P:K=8:15:7, organic matter content is 15%, then ridging, ridge height 35cm, ridge width 80cm, furrow width between two ridges 120cm;

[0033] (2) Tobacco seedling planting and transplanting: In the middle and late May, when the tobacco seedlings grow 6-8 leaves, they are planted in the field soil, the transplanting density is 1000 plants / mu, and each ridge is planted in a single row with a distance of 55cm. Colonization;

[0034] (3) Tobacco topdressing: In the middle and late June, remove th...

Abstract

The invention belongs to the technical field of crop cultivation, in particular to a rotation planting method for tobacco and fritillaria. The rotation planting method comprises the following steps of(1) soil preparation and base fertilizer application; (2) tobacco seedling transplanting; (3) tobacco topdressing; (4) tobacco leaf harvesting; (5) tobacco field soil preparation; (6) fritillaria seed treatment; (7) fritillaria planting; (8) field management; (9) water and fertilizer management; and (10) fritillaria harvesting. According to the planting method, by utilizing the growth characteristics of the tobacco and the fritillaria, the tobacco and the fritillaria are planted in a combined manner; after the planted tobacco is harvested, soil preparation is immediately performed again and the fritillaria is planted, and thus, land space can be fully utilized, and the economic benefits are improved; and by mutual rotation of the tobacco and the fritillaria, reciprocal successive croppingobstacles can also be relieved, the occurrence probability of diseases and pests is reduced, the growth of the tobacco and the fritillaria is promoted, the yield and the quality of the tobacco and the fritillaria are indirectly improved, and the incomes of a tobacco grower can be greatly increased from single-season planting.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for planting tobacco and Fritillaria in rotation. Background technique [0002] Tobacco is an important economic crop. At present, in the process of tobacco planting, most of the tobacco fields (especially mountain tobacco fields) adopt flue-cured tobacco monoculture. After planting tobacco for one season, they are free to plant tobacco again in the next year, resulting in a low crop multiple cropping index. The waste of light resources, low income, and serious obstacles to tobacco continuous cropping have greatly affected farmers' planting benefits. [0003] Fritillaria is a perennial herb whose bulbs are used as medicine, which has the functions of clearing heat and moistening lungs, relieving cough and reducing phlegm. There are also many well-known patent medicines, such as Chuanbei Piquat Cough Lotion, Chuanbei Qiuli Cream, etc. There are many...
