Embodiment

[0047] A piece of cultivated land that has been cultivated continuously for several years and has been polluted by pesticides and chemical fertilizers shall be treated as follows:

[0048] On the first day, water the ground thoroughly with the water prepared above; due to the presence of pollutants in the soil, it can be found that after watering, the water in the puddle has foam and is very dirty; from the second day, use a rotary tiller to turn it over Generally speaking, at the beginning of the treatment stage, the soil is not easy to turn, especially for clay soil, it can be turned only once a day; as the pollutants in the soil settle deep into the soil, the turning will become easier and easier. In the later period, the number of times of turning the ground every day can be increased according to the situation; the turning of the ground lasts until the 7th day; this can be regarded as a course of treatment.

[0049] On the eighth day, use the water prepared above to irrig...

Abstract

The invention relates to a soil treatment method comprising (A) soil washing: washing soil with water treated with a glass composition to remove pollutant in soil; (B) fertilization: fertilizing the soil with a fertilizer being excrement of poultry and livestock drinking the water treated with the glass composition, wherein the glass composition includes 50-99 wt% of glass and 1-50 wt% of quartz-feldspar porphyry or magnetite. The glass includes one or more from SiO2, Na2CO3, CaCO3, Na2B2O4.5H2O, NaNO3, Al(OH)3, TiO2, ZnO, Fe2O3, Li2CO3, K2CO3, KNO3, AlPO4 and H3BO3. The treated soil can be used for planting agricultural and sideline products which are free of pesticide residue, heavy metal and harmful bacteria, are very long in shelf life and are high in nutritional value.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for treating soil. Background technique [0002] At present, food safety issues have attracted much attention. In modern agriculture, pesticides and herbicides are used when crops suffer from diseases, pests and weeds. The current common sense is that to prevent crops from being damaged by diseases and insect pests, it is necessary to use drugs to disinfect the soil before planting, so that the soil is in a sterile state. In addition to pesticides, herbicides, soil fumigants, etc., there are various problems in contemporary agriculture. [0003] The standard composition table published by the Japan Science and Technology Agency in 2001, a comparison of the nutrient content of vegetables in the 50 years from 1952 to 2001. In 50 years, only 52.5%, 23.3%, and 15.4% of VA, Vc, and Fe in spinach are left, that is, vitamin A is reduced by half, vitamin C is reduced by one-fourth,...
