preparation example Construction

[0042] In the farmland amphibious fallow method provided by the present invention, in the step of harvesting the aquatic plants, the aquatic plants are harvested and transferred to the farmland after they are mature. The vigorously growing aquatic plants in the ring ditch can be mowed and covered in the field to realize the transfer of eutrophication substances to the shore. It can not only quickly improve the fertility of the farmland, but also prevent the paddy field from overgrown with weeds due to the mulching effect. In addition, the overgrown aquatic plants can also be salvaged, dried and fermented to prepare aquatic plant fertilizers. Wherein, the preparation method of the aquatic plant fertilizer includes: adding microbial liquid and quicklime to the aquatic plants. The microbial bacterial liquid mainly includes photosynthetic bacteria (Photosynthetic Bacteria), Bacillus subtilis (Bacillus subtilis), lactic acid bacteria (lactic acid bacteria), yeast (yeast) and other ...

Embodiment 1

[0048] 1) Farmland improvement: set up a ring ditch around the farmland polluted by heavy metals and pesticide residues, the ring ditch is provided with a water body, the slope ratio of the ring ditch is 1:1.5; the width of the ring ditch is 2m; The depth of the ring ditch is 1m;

[0049] 2) Sowing milk vetch: sow milk vetch in the farmland around October; sow milk vetch Xiangzi No. 1 at an amount of 2 kg / mu;

[0050] 3) plowing and deep retting: in spring, when the milk vetch is in full bloom, it will be plowed 15cm deep into the field; and the water level will be raised to submerge the farmland; before deep plowing, quicklime will be evenly sprinkled, and the consumption will be about 50 kg / mu;

[0051] 4) Aquatic planting: Plant evergreen bitter grass for four seasons in the ring ditch in spring or summer, and replant Hydriella verticillium as needed in the later stage; plant Elodea in autumn and winter to ensure that there are grasses underwater all year round, and the cov...

Abstract

The invention relates to the technical field of agriculture, in particular to an amphibious fallow method for farmland. The method comprises the following steps of 1) farmland reconstruction, specifically, a circular ditch is arranged around the farmland, a water body is arranged in the circular ditch, and the slope ratio of the circular ditch is 1: 1-1: 3; the width of the circular ditch is 2-5m; and the depth of the circular ditch is 0.5-1.5 m; 2) water fallow in winter, specifically, astragalus sinicus are sowed in the farmland in October every year; 3) ploughing and deep retting in spring, specifically, the astragalus smicus are deeply ploughed into the field when the astragalus smicus is in a full-bloom stage in spring, and the water level is raised to submerge the farmland; 4, aquatic plant planting, specifically, aquatic plants are planted in the circular ditches in spring or summer; 5) aquatic plant harvesting, specifically, the aquatic plants after vigorous growth are harvested, and transferred the aquatic plants to the farmland for composting; and 6) aquaculture, specifically, after aquatic plants are planted, aquatic animals are put into the water body of the circular ditch. According to the method, two-year fallow is carried out in turn according to the mode, heavy metal such as Cd in the soil can be passivated in situ, and degradation of pesticide residues such as organophosphorus and organochlorine can be achieved; the effect of fallow for 5-6 years internationally is achieved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for farmland amphibious fallow. Background technique [0002] In most of the agricultural production process in our country, a large amount of chemical fertilizers and pesticides are generally used in order to increase crop yields or prevent crops from appearing pests. The main pesticides used include organochlorine pesticides, organophosphorus pesticides, carbamates and pyrethroids. Organochlorine pesticides are a large class of organic insecticides containing chlorine atoms, mainly including HC6, aldrin, DDT, lindane, etc. Organophosphorus pesticides mainly refer to organic compound pesticides containing phosphorus, such as dimethoate and dichloride Insects etc. Carbamate pesticides Nitrogen-containing carbamate derivatives, such as amocarb, carbaryl, aldicarb, etc. Pyrethroid pesticides are biomimetic insecticides of natural pyrethrins, such as bifenthrin and...
