Problems solved by technology
Although Wenshan has the necessary environmental conditions for the production of high-quality flue-cured tobacco, with the prominent conflicts between tobacco and grain and the one-sided pursuit of economic benefits by some tobacco farmers, continuous cropping and irregular use of chemical fertilizers and pesticides in Wenshan tobacco fields have become particularly serious in recent years. Prominent, leading to the reduction of soil fertility and self-repair ability of tobacco fields in Wenshan area, which eventually lead to aggravation of diseases and insect pests in tobacco fields, and decline in the yield and quality of tobacco leaves

Embodiment 1
[0014] Embodiment 1: A kind of tobacco planting soil conservation method of preventing and treating bacterial wilt using straw as raw material,
[0015] 1) Dry the corn stalks in the sun, then crush them into small pieces of 2-3 cm, spread the crushed corn stalks evenly on the tobacco field before tobacco planting, plow the tobacco field, and mix the crushed corn stalks with the soil; Straw consumption is 7500kg / m 2 -15000kg / m 2 ;
[0016] 2) Irrigate the tobacco field with water until the water reaches saturation;
[0017] 3) Cover the tobacco fields with agricultural plastic film for 21 days.
[0018] 4) After 21 days of coverage, perform technical measures such as ridging, transplanting, field management, and baking in accordance with the technical requirements of flue-cured tobacco production in Wenshan Prefecture. The variety of flue-cured tobacco is Yunyan 87; the fertilizer used is special fertilizer for tobacco, base fertilizer (N-P 2 o 5 -K 2 O=8-16-22), topdre...

The invention discloses a tobacco-planting soil conservation method for preventing and treating bacterial wilt by taking straws as raw materials. According to the method for preventing and treating tobacco-planting soil bacterial wilt by taking corn straws as raw materials, the using method has simple operation steps and does not need special treatment, and the adopted corn straws widely exist inagricultural production, are low in price, easy to obtain, wide in source and good in environmental protection. According to the method, corn straws with a specific dosage are mixed into soil, and a treatment mode of covering the soil by flooding is adopted, so that the method is not only beneficial to the growth of tobacco plants and enables the agronomic characters of the tobacco plants to perform better, but also has a better prevention and control effect on bacterial wilt and increases economic benefits, particularly, the effect is best when the dosage of corn straws is 7500 kg / m2.
Description
technical field [0001] The invention relates to the field of tobacco planting soil conservation, in particular to a tobacco planting soil conservation method for preventing bacterial wilt using straw as a raw material and an application thereof. Background technique [0002] Tobacco fields are the environmental conditions for tobacco plants to survive, and they are also essential environmental factors for the production of high-quality tobacco leaves. Although Wenshan has the necessary environmental conditions for the production of high-quality flue-cured tobacco, due to the prominent conflicts between tobacco and grain and the one-sided pursuit of economic benefits by some tobacco farmers, the phenomenon of continuous cropping and irregular use of chemical fertilizers and pesticides in Wenshan tobacco fields has become particularly serious in recent years. Prominent, resulting in the reduction of soil fertility and self-healing ability of tobacco fields in Wenshan area, whi...
