Abstract
The invention belongs to the crop cultivation technology and relates to an organic cultivation method for soybean. The organic cultivation method for soybean comprises the following steps of: sowing vetch seeds in a field in which soybean seeds need to be sowed between September and October in the middle and lower reaches of Yangtze River, wherein 4-5kg of vetch seeds is sowed in the filed per mu, and the vetch seeds live through the winter naturally; plowing the field between March or April when the vetch seedlings turn green and the first ten days of June when the vetch seedlings flower; transplanting or sowing soybean seeds, and managing the field conventionally; and harvesting, wherein during the growth of the soybean seedlings, no fertilizer, chemical pesticide and herbicide needs to be applied, and only empedobacter-brevis microbial pesticide needs to the sprayed when the soybean seedlings are damaged by lepidoptera pests. By reasonably arranging the growing season of the vetch seedlings and the soybean seedlings and fully utilizing the nitrogen fixation and weed suppression functions of the vetch seedlings, the use amount of the chemical pesticide, the herbicide and fertilizer can be reduced under the condition of not affecting the yield of soybean. The organic cultivation method for soybean meets the organic cultivation needs.
Description
Technical field
The invention belongs to the arviculture technology, relate to a kind of soybean organic farming method.
Background technology
In the existing soybean culture process, need to use in a large number chemical pesticide and weed killer herbicide for pest control and crop smothering, cause environmental pollution, improve production cost.Also will use chemical fertilizer for improving output, not only cost is high, also affects soil property.Do not meet the requirement of green organic agricultural.
Sweet potato is leguminous plant, has fixed nitrogen and presses down careless effect, as agriculture green manure, is generally used for rice field multiple cropping and cornfield interplanting, utilizes it to improve the record of soybean culture but there is no.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of when not reducing crop yield, reduce agricultural chemicals and weed killer herbicide chemical contamination, reduce fertilizer application, soybean organic farming method that planting cost is low.
Soybean organic farming method of the present invention is: at In Middle And Lower Reaches of Changjiang River, in the field that will plant soybean at first sow sweet potato to October September, broadcasts sweet potato kind 4-5 kilogram, grown by the sweet potato overwintering for every mu; To the growth of turning green the Second Year 3-4 month, to flowering stage early June, the rotary tillage of sweet potato plant is entered in the soil; Then transplant or the sowing soybean, carry out conventional field management; Do not use chemical fertilizer in the soybeans they grow process, do not use chemical pesticide and weed killer herbicide, only when lepidoptera pest occurs, adopt short steady bacillus microorganisms pesticide spraying to administer, until soybean harvest.
Method of the present invention took full advantage of the fixed nitrogen of sweet potato and presses down the grass effect by the season of growth of reasonable arrangement soybean and sweet potato, can reduce the use of chemical pesticide, weed killer herbicide and chemical fertilizer when not reducing soybean yields, had satisfied the needs of organic farming.
Embodiment
The embodiment of the invention is as follows: southern area of Jiangsu Province, by the end of September, in the field that will plant soybean, at first sow sweet potato, and broadcast 5 kilograms of sweet potato kinds for every mu, by the growth of sweet potato overwintering, to the growth of turning green the Second Year 3-4 month; To flowering stage early June, the sweet potato plant is turned in the soil; Then transplant or the sowing soybean, carry out conventional field management, do not use chemical fertilizer in the soybeans they grow process, do not use chemical pesticide and weed killer herbicide, only adopt short steady bacillus pesticide spraying to administer when lepidoptera pest occurs, until soybean harvest, the soybean average yield per mu can reach 150 kilograms.
Claims (1)
1. soybean organic farming method, it is characterized in that: at In Middle And Lower Reaches of Changjiang River, in the field that will plant soybean at first sow sweet potato to October September, broadcasts sweet potato kind 4-5 kilogram, grown by the sweet potato overwintering for every mu; To the growth of turning green the Second Year 3-4 month, to flowering stage early June, the rotary tillage of sweet potato plant is entered in the soil; Then transplant or the sowing soybean, carry out conventional field management; Do not use chemical fertilizer in the soybeans they grow process, do not use chemical pesticide and weed killer herbicide, only when lepidoptera pest occurs, adopt short steady bacillus microorganisms pesticide spraying to administer, until soybean harvest.
