Problems solved by technology

Carbendazim has a stable structure and a long residual period in the soil. Due to its certain migration activity, it has a greater risk of pollution to groundwater
[0003] At present, the phenomenon of soil acidification caused by excessive application of physiologically acidic fertilizers has become very common, especially in vegetable field soils. The most widely used fungicide in vegetable fields, therefore, the risk of groundwater pollution by carbendazim in acidified soil in vegetable fields is extremely high
At present, the research on carbendazim mainly involves its drug efficacy, adsorption and leaching characteristics in soil, and the residue law in plants, etc. There is no report on the method of effectively reducing the pollution of carbendazim to groundwater in vegetable fields.

Embodiment 1

[0031] The experiment was carried out in a vegetable greenhouse in Jingyue District, Changchun City.

[0032] 1. Before planting crops, add 2 kg of slaked lime to each square meter of vegetable field black soil (soil pH value is 5.1, organic matter content is 21.2 g / kg, physical clay content of particle size less than 0.01 mm is 23.18%), Make the soil pH 6.2;

[0033] 2. Chop the straw into small pieces of 0.7 cm, and evenly sprinkle it in the black soil with a pH value of 6.2 obtained in step 1. The application rate of the straw is 2 kg / m 2 , the content of organic matter in the surface soil is 30.7 g / kg; the straw is the dry straw of tomato, beans and pepper;

[0034] 3. The soil obtained in step 2 is tilled, and the depth of rotary tillage is 15 cm, and the ridges are drilled according to the standards of ridge spacing 60 cm and ridge height 15 cm;

[0035] 4. Dilute the soil obtained in step 3 to 0.2 kg / m 2 Apply ammonium bicarbonate, the depth of fertilization is 15 cm...

Embodiment 2

[0040] The test was carried out at the Xingfu Township Vegetable Experimental Base in Nanguan District, Changchun City.

[0041] 1. Before planting crops, add alkaline soil (alkaline soil Taken from Taohaotai Township, Qianguo County, Songyuan City, the pH value is 10.6) and slaked lime, the dosage of alkaline soil and plant ash per square meter of vegetable field black soil is 7 kg and 3 kg respectively, and the pH value of vegetable field black soil is 6.1;

[0042] 2. After applying the organic fertilizer with an organic matter content of 270 g / kg to the soil obtained in step 1 according to 5 kg per square meter, the organic matter content of the surface soil increased to 33.4 g / kg; the organic fertilizer was mainly chicken manure. Raw materials are decomposed;

[0043] 3. The soil obtained in step 2 is tilled, and the depth of rotary tillage is 15 cm; the ridges are drilled according to the standards of ridge spacing of 60 cm and ridge height of 15 cm;

[0044] 4. Dilut...

Abstract

The invention relates to a method for reducing groundwater pollution caused by carbendazim in a vegetable field, belonging to the technical field of prevention and control of agricultural nonpoint source pollution. The method comprises the steps of: adding alkaline materials into soil of the vegetable field prior to planting of crops until the pH value of the soil is more than or equal to 6.0; applying organic materials in the soil until the content of organic matters in surface soil of 0-15cm is 30-45g / kg; tilling the soil, wherein the depth of rotary tillage is less than or equal to 15cm; and applying fertilizers into the tilled soil, wherein the fertilizers can be chemical alkaline fertilizers or physiological alkaline fertilizers. By adopting the method, the risk of groundwater pollution can be reduced effectively, and the effect of emission reduction can be realized. Meanwhile, excessive loss of carbendazim in the soil can be avoided by the method, the efficacy of carbendazim can be ensured, and certain effect of improving the efficacy can also be achieved.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of agricultural non-point source pollution, and in particular relates to a method for reducing groundwater pollution caused by carbendazim in vegetable fields. Background technique [0002] As an important means of ensuring agricultural harvest, chemical pesticides play a very important role in agricultural production. However, due to the long-term unscientific use of pesticides by people, the large-scale use of highly toxic, high-residue, and refractory pesticides, we are faced with an increasing number of pesticides. Environmental problem of pollution. Carbendazim belongs to the systemic fungicides of benzimidazoles. It has the advantages of high efficiency and broad antibacterial spectrum and has been widely used. It is often used for brown spots on various crops such as vegetables, Chinese medicinal materials, rice, wheat, cotton, and fruit trees. Prevention and control of dise...
