Problems solved by technology

[0002] There are many conditions that affect tobacco planting, especially in the case of the shortage of planting land in our country, the conflict between grain and tobacco is prominent; and the tobacco planting area has soil degradation and aggravated diseases and insect pests due to the single planting of tobacco leaves for many years, which seriously affects the yield and quality of tobacco leaves
At the same time, because flue-cured tobacco is harvested from leaves, it will be more seriously affected by wind, hail, disease and other disasters than other crops, and the risk of planting is greater than other crops

Embodiment 1

[0016] A method for planting tobacco and potato intercropping, the steps are as follows:

[0017] 1. Variety selection: Determine the flue-cured tobacco variety and the sweet potato variety based on the soil of the planting site. The sweet potato must choose a short seedling variety to reduce the impact on the growth space of the tobacco plant;

[0018] 2. Ridging: Tobacco and potato intercropping, the row spacing of tobacco plants, and the row spacing of tobacco plants and sweet potatoes are the same;

[0019] 3. Fertilization: 5.5-8kg of pure nitrogen in fertilization per mu in medium-fertility tobacco fields, the ratio of nitrogen, phosphorus and potassium is 1:1:2-3, and the high and low-fertility tobacco fields are respectively reduced or increased by 0.5±0.1kg pure Nitrogen; such as NC82, K326, Yunyan 85 acres of pure nitrogen 6.5kg, China Tobacco 100 acres of pure nitrogen 8kg, NC89 acres of pure nitrogen 5.5kg;

[0020] 4. Transplanting: the transplanting period of to...

Embodiment 2

[0025] The potato-tobacco intercropping model is a three-dimensional planting, which can increase the land multiple cropping index and alleviate the conflict between grain and tobacco. In the tobacco and potato "2+1" intercropping mode, in the second year of planting, a row of tobacco ridges and potato ridges are exchanged to avoid repeated cropping in the tobacco field; in the tobacco and potato "2+2" and "1+1" intercropping modes, When planting in the second year, there is no need to change the land, and the tobacco ridge and the potato ridge can be exchanged and planted on the same land, realizing automatic stubble change in the tobacco field, which effectively alleviates the problem that crop rotation is not easy to achieve due to the shortage of land resources, and realizes Tobacco field natural crop rotation.

[0026] The planting area and planting groups of tobacco and potato intercropping are stable, and a part of the potato field is increased as the basic tobacco fiel...

Abstract

The invention discloses an intercropping method for tobacco and sweet potatoes. The intercropping method comprises the following steps: I, selecting varieties; II, ridging; III, applying fertilizers; IV, transplanting; V, performing field management, picking up and baking. Through intercropping of tobacco and sweet potatoes, natural crop rotation in a tobacco field is realized, the basic tobacco field area is stabilized, the plant diseases are effectively relieved, the tobacco planting risk is lowered, the tobacco leaf quality is good, the overall benefit is high, the tobacco planting initiative of tobacco growers is improved, and the tobacco grower team is stabilized.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for planting tobacco and potato intercropping. Background technique [0002] There are many conditions that affect tobacco planting, especially in the case of the shortage of planting land in our country, the conflict between grain and tobacco is prominent; and the tobacco planting area has soil degradation and aggravated diseases and insect pests due to the single planting of tobacco leaves for many years, which seriously affects the yield and quality of tobacco leaves . At the same time, because flue-cured tobacco is harvested from leaves, it will be more seriously affected by wind, hail, disease and other disasters than other crops, and the risk of planting is greater than other crops. [0003] Therefore, a reasonable planting method is needed to solve the single planting of tobacco fields, realize the natural rotation of tobacco fields, stabilize the planting area of ​...
