Description
Technical field
The present invention relates to agricultural chemicals and fertilizer integrated technique field, be related to by insecticide, bactericide, fertilizer, sustained release agent and
The slow-released pesticide of other auxiliary agents composition and the composition of chemical fertilizer a great number of elements N P and K, said composition are used for the base fertilizer of tobacco.
Background technology
The annual sunshine draft plant of Solanaceae of Nicotiana, with wide adaptability, plasticity is strong the features such as, be a kind of yield with
The leaf that quality is laid equal stress on uses industrial crops.Up to the present, tobacco is in existing more than the 400 years history of the plantation of China.There is data to unite
Meter, China tobacco planting area, yield etc. rank first in the world, and tobacco is one of important industrial crops of China, but with
The increase of the continuous cropping time limit, the deterioration of tobacco leaf living environment, pest and disease damage take place frequently, and quality of tobacco is affected.
Agricultural chemicals be mainly used in preventing and treating crop in harmful organism, fertilizer necessary nutrition for plant growth is provided, they are all
Required for crop, and when the two in the same time required for crop when, exactly medicine fertilizer development provide ample scope for abilities.Medicine
Fertilizer has also agreed with the new demand of modern agriculture to a certain extent.Medicine and fertilizer are united two into one, and fertilising and laxative are worked into whole twice
It is combined into and once works, be conducive to raising labour efficiency, liberating rural labour reduces agriculture production cost.Importantly, medicine
Transboundary combine with fertilizer, by the collocation of science, it is possible to achieve 1+1>2 increment effect.
At present in published medicine fertilizer patent, Publication No. CN102633566A, CN106242813A,
The patents such as CN105777416A, CN 102964179B, CN102303990B, CN104987167A, CN103864510A its
Agricultural chemicals used is all non-nicotinoids, Publication No. CN102276356 B, CN105237255A, CN105085087A,
The patents such as CN104177196A its agricultural chemicals used only has desinsection or bactericidal action；Although the patent of publication number CN105746568A its
Insecticide includes Diacloden, clothianidin and imidacloprid, but not comprising chlorine fluorine cyanogen insect amide, four chlorantraniliproles, while its agricultural chemicals
Part is also without slow release.
Although the patent of the A of publication number CN 106106498 its insecticide is Diacloden, bactericide is Fluoxastrobin, and it is only
It is a kind of common granular pesticide, it only has the function of desinsection and bactericidal action without fertilizer, the A of CN 103027064
Only it is the seed treatment containing clothianidin, the CN101642097A only granules containing clothianidin, the A of CN 104488952 are only
Common formulations containing Diacloden and Biphenthrin, four do not belong to same field with the present invention.
Therefore, research is exclusively used in the fertilizer containing sustained-release pesticides of tobacco, for tobacco planting area, the yield Deng Junju worlds
First China is most important.
The content of the invention
The technical problem to be solved in the present invention is to provide one and grows tobacco the special fertiliser granulates agent containing sustained-release pesticides and its system
Method and application, the agricultural chemicals and fertilizer that are processed by sustained release agent of the present invention mix the stability that agricultural chemicals is improve when depositing, extension agricultural chemicals
The term of validity, and realize the controllable release of agricultural chemicals, after reaching or basically reaching applied once, the fertilizer needed for tobacco is met
Meanwhile, the main diseases and insect pests to deuterogenesis are effectively prevented and treated purpose.
In order to solve the above technical problems, the technical solution used in the present invention is：One grow tobacco it is special containing sustained-release pesticides
Fertiliser granulates agent, in terms of each component mass percent, constitutes as follows：

Note：1. varieties of plant NC82, every mu with agricultural chemicals fertilizer 50kg；2. every mu of A of control tobacco NPK 40kg；Oriental tobacco budworm
Preventing and treating is sprayed with 20% Rynaxypyr suspending agent once；Aphid is stretching the root phase and prosperous long-term is using 10% imidacloprid wettable powder
Each preventing and treating is once；Balck shank is not prevented and treated.3. every mu of B of control tobacco NPK 40kg, pest and disease damage is not prevented and treated.
4. the preventive effect of disease pest is and compares B and be compared；Rate of growth is and compares A and be compared.
According to the characteristic of sustained release agent, the speed of sustained release agent J1, J2 and J3 its release agricultural chemicals from fast to slow, J4 and J3 agricultural chemicals
Rate of release is suitable.As it can be seen from table 1 the release speed of sustained-release pesticides has little to no effect to the preventive effect for stretching root phase aphid,
But the prevention effect influence of the aphid and two balck shanks of breeding time gone on oriental tobacco budworm and prosperous length is very big, wherein most
The preventive effect J3 for the treatment of more than J2, J2 more than J1, J4 and J3 preventive effects are suitable.
The above is only the preferred embodiment of the present invention, it is noted that it is right that above-mentioned preferred embodiment is not construed as
