Method of production of crops in the conditions of intensive land use

 

(57) Abstract:

The invention relates to the technology of crop production. The method provides for the handling of pesticides and/or pesticides, disposal and cleaning of circulating and/or wastewater composite sorbent. Composite sorbent contains activated carbon and zeolite-containing rocks. After exhaustion of the sorption capacity of the composite sorbent is separated and used for the processing plants. The invention allows to reduce the consumption of pesticides, agrochemicals and composite sorbent, stabilize yields.

The invention relates to the technology of production of crops in the conditions of intensive land-use.

There is a method of production of crops in the conditions of intensive land use, capable of handling pesticides and/or pesticides, disposal and cleaning of circulating and/or wastewater composite sorbent containing activated carbon and zeolite breed (Belousov B. C., S. Shmelev, I. Application of new sorption materials in addressing agri-environmental problems // proceedings of international scientific-practical confushed pesticides and/or pesticides and composite sorbent.

The technical result of the invention is to reduce the consumption of pesticides, agrochemicals and composite sorbent.

This result is achieved in that in the method of production of crops in the conditions of intensive land use, capable of handling pesticides and/or pesticides, disposal and cleaning of circulating and/or wastewater composite sorbent containing activated carbon and zeolite breed, according to the invention after completion of the sorption capacity of the composite sorbent is separated and used for treatment of plants.

The method is implemented as follows.

Zeolite-containing rock is crushed and mixed with activated charcoal. The obtained composite sorbent used for cleaning recycling or waste water discharged from agricultural land, which in the conditions of intensive land to produce crops. Technology intensive land use involves the application of pesticides and agrochemicals in a certain timeframe. After carrying out such treatments pesticides and chemicals are in the waste water and are sorbed used composition is needed granularit, dried and used for treatment of plants at the time recommended for pesticide or agrochemical, which was done cleaning the exhaust water. Dosage when using waste composite sorbent is carried out in terms of the sorbed amount of pesticide or agrochemical. In such circumstances, is the repeated use of pesticides and agrochemicals, which was irreversible loss. In addition, zeolite rock, made in conjunction with pesticides or agrochemicals, retards the leaching of soil nutrients and minerals, and also introduce additional pesticides and agrochemicals, which reduces their migration and longer term use regular doses of composite sorbent. Studied under experimental review zeolite-containing rocks Hadyzhensk and Absheron fields after use in the composition of the sorbent when cleaning exhaust retain water in its composition necessary for the mineral nutrition of the plant macro - and micronutrients, which further improves the conditions of mineral nutrition of plants during the implementation of the proposed method.

To confirm achieve tekhnicheskogo deposits have a high sorptive capacity for purification of exhaust water from nitrogen fertilizers. Tested activated carbons brands BAU, CR, AG-3, ALP, GLG, bupk, SBP, TC, CT have a high sorptive capacity for purification of exhaust water from organic compounds, in particular of herbicides 2,4-D, 2M-4, 2M-HP, Basargan, Dalapon, Hordes, Picloram, Propane, Simazine, Trifluralin, insecticide Metaphos, fungicide Rice. The sorption capacity of the composite sorbent is set by the ratio of zeolite-containing rocks and activated carbon, and can vary in doses, depending on usage time according to the schedule treatments of pesticides and agrochemicals. Depending on the composition of the sorbed pesticides and agrochemicals exhaust composite sorbent can be used for the treatment of vegetating plants or presowing treatment of seeds. For treatment of vegetation separated composite sorbent is advisable to pelletized and dried. For use when carrying out pre-treatment of seeds separated composite sorbent, it is advisable to dry and grind to powder.

Experimental verification for the production of crop products was conducted on three soil types: leached Chernozem malohumusni with the AMI served as spring wheat varieties Kharkiv 17, winter wheat varieties Stefanka, winter barley varieties Skorokhod, corn hybrid Krasnodar 303 DIA, sunflower hybrid Krasnodar 917, soybean variety Armavir.

Serial threefold cultivation of the test cultures in the control plot, the treatment of which was carried out with the use of pesticides and agrochemicals in accordance with the recommended schedule of treatments for all types of soil, and all kinds of test cultures showed a trend of slow decrease in productivity. With partial replacement of pesticides and agrochemicals equivalent to the amount of exhaust composite sorbent tendency to fall in yields disappears when making zeolite-containing rocks in the amount of 20 mass% of applied pesticides and agrochemicals on leached Chernozem and 25% on other types of soils. The number of activated carbons on this indicator is not affected. At the same time, the period of use of doses of a combined sorbent in cycles of cultivation in the control is constant, and in the experience increases in average a minimum of leached Chernozem 2.5 and 3.7 times, respectively, for a maximum of alluvial-meadow soils 3.1 and 5.2 times, respectively.

Thus, preseminal stabilize the yield of crops.

Method of production of crops in the conditions of intensive land use, capable of handling pesticides and/or pesticides, disposal and cleaning of circulating and/or wastewater composite sorbent containing activated carbon and zeolite breed, characterized in that after completion of the sorption capacity of the composite sorbent is separated and used for the processing plants.
