Description
Technical Field
The invention belongs to the technical field of medical fertilizers, and particularly relates to a novel special fertilizer for strawberries.
Background
The fruit juice of the perennial herb of strawberry belonging to Rosaceae is delicious, good in taste and rich in nutrition. During the strawberry planting process, the strawberry gray mold is affected by various diseases and insect pests, wherein the strawberry gray mold is one of important diseases affecting the safe production of the strawberry, is caused by Botrytis cinerea (Botrytis cinerea) infection, and can damage all overground parts of plants, and the infection to flowering phase and fruits is the heaviest, so that the yield and quality of the strawberry are reduced, and serious economic loss is caused. At present, chemical control is still a common and effective means for controlling gray mold of strawberries, and main control agents are as follows: procymidone, boscalid, thiram, pyrimethanil, etc., but because of frequent and unreasonable administration for a long period of time, strawberry gray mold gives different degrees of resistance to various bactericides, so development of novel pesticide products is necessary.
CN202110102365.5 discloses a novel fertilizer special for eucalyptus and a preparation method thereof, and in the specification, the fertilizer has a better synergistic effect on gray mold pathogenic bacteria of eucalyptus seedlings when being compounded by farnesol and mandipropamid or pyraclostrobin, and can effectively prevent and remove gray mold of eucalyptus seedlings. Application number CN201810759419.3, patent name farnesol discloses molecular formula, chemical name and chemical structural formula of farnesol in application as sterilizing synergist in plant gray mold control.
The compounding of pesticide active ingredients with different action mechanisms is an effective and quick way for developing new pesticide products and preventing and controlling pest and disease resistance at present. The applicant entrusts the teacher of the Guangxi Zhuang autonomous region agricultural academy to screen and compound the existing medicament for preventing and treating gray mold, and finds that the synergistic effect can be generated when the farnesol and the pyraclostrobin, the cyprodinil or the tebuconazole are compounded according to a certain mass ratio, and no report on the compounding of the farnesol and the pyraclostrobin, the cyprodinil or the tebuconazole is found at present.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
Disclosure of Invention
The invention aims to provide a novel special strawberry fertilizer which contains components such as a sterilizing composition, a water-soluble fertilizer and the like, wherein the sterilizing composition can prevent and treat gray mold of strawberries, the water-soluble fertilizer can provide nutrition for growth of strawberries, and the yield and quality of strawberries can be improved by mutually matching the water-soluble fertilizer with the sterilizing composition, so that the economic income is improved.
In order to achieve the above purpose, the present invention provides the following technical solutions:
the first aim of the invention is to provide a sterilization composition, wherein the effective components of the sterilization composition are compounded by farnesol, pyraclostrobin, cyprodinil or tebuconazole.
Preferably, the mass ratio of the farnesol to the pyraclostrobin is 1-5:40-1.
Preferably, the mass ratio of the farnesol to the cyprodinil is 1-20:60-1.
Preferably, the mass ratio of the farnesol to the tebuconazole is 1-30:7-1.
The second aim of the invention is to provide a novel special strawberry fertilizer which comprises the following components in percentage by weight: 1-15% of the bactericidal composition, 30-65% of water-soluble fertilizer, 2-5% of dispersing agent, 1-3% of wetting agent and 100% of filler are supplemented, and the raw materials are uniformly mixed in a mixing kettle during manufacturing, and then crushed by an airflow crusher, wherein the manufacturing method is the prior art; when in use, the foliar spray is firstly diluted by clear water and then sprayed on the foliar.
Preferably, the water-soluble fertilizer is selected from one or more of potassium sulfate, ammonium chloride, potassium nitrate, zinc sulfate and sodium octaborate tetrahydrate.
Preferably, the dispersing agent is selected from one or more of sodium lignin sulfonate, calcium lignin sulfonate and sodium dodecyl benzene sulfonate.
Preferably, the wetting agent is selected from one or more of gleditsia sinensis powder, nekal BX, silkworm excrement and soapberry powder.
Preferably, the filler is selected from one or more of kaolin, attapulgite, white carbon black and talcum powder.
Compared with the prior art, the invention has the following beneficial effects:
(1) The active ingredients in the bactericidal composition have synergism on the pathogenic bacteria of the strawberry gray mold within a certain mass ratio range, can improve the control effect on the strawberry gray mold, can reduce the application amount of pesticides, reduce the control cost and reduce the pesticide residue, and can provide support for developing novel pesticide products.
(2) The special fertilizer for the strawberries contains the components such as the sterilizing composition, the water-soluble fertilizer and the like, wherein the sterilizing composition can prevent and treat gray mold of the strawberries, the water-soluble fertilizer can provide nutrition for the growth of the strawberries, the yield and the quality of the strawberries can be improved, and the economic income is increased.
