Method for overcoming soil continuous cropping obstacles by intercropping flue-cured tobacco with A. chinensis and wheat

Abstract

The invention discloses a method for overcoming soil successive cropping obstacles by using smooth vetch and wheat interplanting flue-cured tobacco. The method comprises the following steps: (1) dividing a land for growing field crops into wide rows and narrow rows; (2) sowing the smooth vetches in the wide rows in August of the first year, and sowing wheat in the narrow rows in November of the first year; (3) mowing the smooth vetches in March of the second year, evenly spreading among wheat rowledges after the smooth vetches are shredded, and then, turning and pressing the smooth vetches spread on the earth surface into a farming layer; (4) furrowing a tobacco planting ridge between every two wheat rowledges in April to May of the second year to transplant the tobacco; (5) after the wheat is harvested in August of the second year, sowing the smooth vetches again among tobacco rows, and alternately planting. According to the method, the smooth vetches are planted, turned and pressed to improve the fertility and the physicochemical property of the soil, improve the microenvironment of the tobacco soil, and bring convenience for beneficial microorganisms in the soil to grow and inhibit the infringement of pathogenic bacteria in the soil, the tobacco successive cropping obstacles can be controlled, and the disease resistance and the stress resistance of tobacco plants can be enhanced.

Description

technical field

[0001] The invention relates to the fields of modern crop cultivation, soil and fertilizer, and in particular to a planting method for overcoming soil continuous cropping obstacles by interplanting flue-cured tobacco with vetch and wheat. Background technique

[0002] Tobacco is an important economic crop in my country and occupies an important position in the national economy. In most tobacco areas in my country, due to years of continuous cropping and long-term use of chemical fertilizers while ignoring the input of organic fertilizers, soil fertility has decreased year by year, soil nutrient supply has continued to be imbalanced, and soil physical properties have deteriorated, hindering the improvement of tobacco leaf quality. The main reason is that continuous cropping causes the reduction of beneficial microorganisms and the increase of harmful microorganisms in the soil, resulting in the serious occurrence of diseases and insect pests, the accumulation ...

[0021] Follow the steps below to implement:

[0022] (1) In August of the first year, light-leaf sweet potatoes were sown in the field. Before sowing, the field was divided into wide and narrow rows, with a width of 100 cm and a narrow row of 20 cm (rows reserved for planting wheat). Spread in wide rows, then turn the topsoil slightly with a combination of intertillage and weeding.

[0023] (2) In early November, sow wheat in narrow rows.

[0024] (3) In mid-March of the second year, the smooth-leaf sweet potato was cut, chopped and evenly spread between the rows of wheat, and then the smooth-leaf sweet potato scattered on the ground was turned over and pressed into the cultivation layer. The amount of turning over the smooth-leaf sweet potato was 1000 kg / mu .

[0025] (4) At the beginning of May, tobacco planting ridges were set up between the rows of wheat for tobacco transplanting. The cross section of the tobacco planting ridges was trapezoidal, with a top width of 50 cm...
