Method for planting and tilling and compacting green manure in advance in soil of tobacco-growing area

Abstract

The invention discloses a method for planting and tilling and compacting green manure in advance in soil of a tobacco-growing area. The method comprises the following steps of: seed selection, sowing, fertilizer and water management, and tillage: selecting high-yield and early-maturing varieties of green manure such as smooth vetch, hairy vetch, common vetch or cow vetch, interplanting green manure seeds in a tobacco field by adopting a broadcast sowing manner in the tobacco-growing area at an altitude being below 1,200m during a picking and baking period of central tobacco leaves from August to early September, arranging matched canals and ditches to ensure drainage and irrigation, after green manure seedlings grow out, broadcasting common superphosphate and urea to promote the growth of green manure, and tilling the green manure into soil with the depth of 10-20cm in winter from December to next January, wherein green manure plants are not exposed to the outside after tillage. The method effectively solves the contradiction among the planting of the green manure in the tobacco-growing area, the tillage of frozen earth in winter and the 'three-priority' technology, improves the soil of the tobacco-growing area, and enhances the soil fertility, so that the quality of tobacco leaves can be improved steadily.

Description

technical field [0001] The invention relates to a method for planting green manure, and more particularly relates to a method for planting and pressing green manure in advance in the soil of a tobacco area. Background technique [0002] Tobacco is a crop that should not be continuously cropped, but the current tobacco agriculture characterized by "large-scale planting, intensive management, specialized division of labor, and information management" makes continuous cropping problems common in tobacco leaf production. In addition, long-term use of chemical fertilizers, Insufficient input of organic fertilizers has led to problems such as structural compaction and soil fertility decline in tobacco fields. However, by planting green manure in the leisure season of the tobacco field, it not only achieves the purpose of reasonable crop rotation, but also can improve the soil, fertilize the soil, and promote the steady improvement of the quality of tobacco leaves. Plowing fro...

Problems solved by technology

[0004] However, according to the survey, the current mode of planting green manure in the soil of tobacco-growing areas in Hubei Province is that the sowing period of green manure is October-November, and the green manure is overturned in April-May of the following year. The "three first" technologies of ridging, fertilizing first, and mulching first caused contradictions in time. At the same time, because green manure was planted in the soil in the tobacco-growing area in autumn and winter, it was difficult to plow the frozen soil in winter in the tobacco-growing area.
