Problems solved by technology

[0005] Deep plowing is the key to solving the problem. However, in current production practice, full-turn deep plowing is often used. The deep plowing degree is shallow, the mechanical strength is high, and the cost is high.

Embodiment 1

[0035] In 2013, we conducted a deep-plow planting experiment of tobacco in Xuancheng City, Anhui Province. Through deep-plowing and mixing the soil within a depth of 60cm, we planted flue-cured tobacco on flat ridges. The test results showed that deep tillage planting can increase the yield of tobacco without significant effect on quality. It can be seen from Table 1 that the yield of tobacco leaves under 60cm deep plowing increased by 26% compared with the conventional treatment.

[0038] *Different letters indicate a significant difference of 5%

[0039] From the perspective of tobacco leaf quality (Table 2), different deep plowing treatments had no significant effect on the quality. These indicators include total sugar, total nitrogen, nicotine and sugar-alkaline ratio of flue-cured tobacco.

Abstract

The invention relates to a red-soil dry sloping field tobacco deep plowing, fertilization and level planting integrated planting method. Soil in a 50cm-deep soil layer is mixed through mechanical strip type deep plowing, fertilization is conducted in a matched manner, then ridges are leveled and finally tobacco is planted. The method is simple and feasible, the planting efficiency of tobacco in red-soil dry sloping fields in south China can be obviously improved, the production risk caused by insufficient rainwater is reduced and the problem of lack in fields for tobacco and staple food grain production is avoided.

Description

technical field [0001] The technology of the invention belongs to the technical field of agricultural planting, and in particular relates to an integrated planting method for deep plowing, fertilization and horizontal planting of flue-cured tobacco on dry slope land in red soil. Background technique [0002] my country is the world's largest producer of tobacco leaves, with more than 1.4 million hectares of tobacco planted each year and an annual output of more than 1.7 million tons of tobacco leaves. Tobacco is an important economic crop in my country and also a major source of tax revenue. The stable production and quality improvement of tobacco leaves is an important basic guarantee for my country's tobacco industry. [0003] The red soil area in southern my country is the main area for tobacco planting. This area has good hydrothermal conditions and is suitable for crop growth. However, the annual precipitation distribution is extremely uneven. Seasonal drought is the m...
