Abstract
The invention provides a method for preventing and controlling pepper root rot through modified calcium cyanamide and belongs to the field of pesticide and chemical fertilizer. According to the method, 50% modified calcium cyanamide is broadcasted around pepper trees through a fertilizer broadcasting or hole fertilizer application method, wherein 20-60 kilograms of fertilizer are applied per mu. According to the fertilizer broadcasting method, 50% modified calcium cyanamide is uniformly broadcasted to soil under crowns and is then evenly mixed with soil. According to the hole fertilizer application method, 6-8 fertilizer application ditches 20 centimeters wide and 20 centimeters deep are dug along the peripheries of crowns under pepper tree crowns, 50% modified calcium cyanamide is uniformly broadcasted in the fertilizer application ditches, and then earthing is conducted, wherein the interval of the ditches is 20-40 centimeters. By means of the method, the pepper tree root rot can be obviously reduced, new root growth is obvious, soil of pepper gardens is improved, the PH value of soil is regulated, and the production and income increase effect can be achieved for pepper.
Description
Technical field
The present invention relates to agricultural chemicals, technical field of fertilizers, particularly relate to the method for nitrolim control bunge pricklyash root maize ear rot.
Background technology
Bunge pricklyash root maize ear rot is embodied in plant root blackening of being injured and rots, and have foreign odor taste, Gen Pi and xylem easily depart from, and xylem be black, and acrial part is leaf to diminish, leaf Huang, branch development are unsound, and when falling ill serious, whole strain death, causes the Chinese prickly ash significantly underproduction.No matter children, in, veteran all may send out that this is sick.Existing prevention and controls has following several usually: 1. draining, drainage trenching, and prevent excess moisture from soaking and flood, particularly Z-bungeanum Maxim more will note draining.2. soil is ploughed deeply, applying organic manure, reasonably combined phosphorus, potash fertilizer, improvement soil structure and aeration status.3. transplanting stock sterilization, 500 times of immersion roots of the thiophanate methyl with 50% 24 hours, then field planting.4. in units of cave, carry out soil disinfection with lime water or vegetation buck before planting, and water normal root water with thiophanate methyl 500 times of liquid of 50% or carbendazim 500 ~ 800 times of liquid of 50%.Above-mentioned several method is unsatisfactory to bunge pricklyash root maize ear rot preventing effectiveness, and takes people's effort.
Summary of the invention
The object of the invention is, for the weak point of existing bunge pricklyash root maize ear rot control, to propose a kind of method adopting modification nitrolim to prevent and treat bunge pricklyash root maize ear rot.
Technical scheme of the present invention is: adopt " spreading fertilizer over the fields " or " spreading manuer in holes " method, be sown in around Chinese pricklyash by the modification nitrolim of 50%, every mu of fertilizing amount is 20 to 60 kilograms." spreading fertilizer over the fields " method is under tree crown, is sown in uniformly on soil by the modification nitrolim of 50%, then it is mixed with soil; Method of " spreading manuer in holes " is under Chinese pricklyash tree crown, dig the dressing furrow 6-8 bar of wide, dark 20 centimeters around tree crown drip, and the spacing of ditch is 20-40 centimetre, is sown in uniformly in dressing furrow by the modification nitrolim of 50%, then earthing.
The present invention has following remarkable result:
1, prevent and treat bunge pricklyash root maize ear rot Be very effective, after using the modification nitrolim of 50%, green pepper tree root maize ear rot obviously alleviates, and new root is obvious, and add the absorption function of root system, Chinese pricklyash growing way is recovered gradually.
2, after using the modification nitrolim of 50%, improve the soil in green pepper garden, have adjusted P in soil H value, make original acid ground trend acid base equilibrium, the pH value of soil is increased between 4.8 to 5.6 by original 4.4, make green pepper set the growth of impaired root regeneration, new root quantity increases 4-5 doubly before fertilising.
3, the inventive method can make Chinese prickly ash reach the effect of increasing income, after fertilising, green pepper tree vane thickness increases, and chlorophyll content improves, thus improves the area and intensity of leaf photosynthesis, greatly reduce because extraneous harmful effect causes Chinese prickly ash shedding, improve Chinese prickly ash Grain number per spike and Chinese prickly ash output.
