History is long, and head is loaded in Shennong's Herbal (1), is classified as low-grades.It is warm in nature, acrid in the mouth, slightly poisonous, returns spleen, stomach, lung meridian.Have dry
Humidifying expectorant, stopping nausea and vomiting by lowering the adverse flow of QI, effect of dissolving lump and resolving mass.The Rhizoma Pinelliae contains alkaloid, sitosterol, polysaccharide, aminoacid, volatile oil, the Rhizoma Pinelliae
The Multiple components such as albumen and inorganic elements (2), is a kind of important Chinese crude drug.Research in recent years also finds, the Rhizoma Pinelliae has anti-
The multiple important works such as tumor, antiearly pregnancy, blood fat reducing, hepatoprotective, arrhythmia, glucocorticoid sample effect and treatment coronary heart disease
With.
Crops are all had a certain degree of Side effect by existing chemical insecticide, can cause soil in various degree
The environmental pollutions such as ground, water source, chemical insecticide improper use can cause crops to produce poisoning, causes crop growth abnormal,
Suppress its photosynthesis, affect crop yield, and second stubble crop be will also result in certain murder by poisoning.
Existing chemical insecticide, is divided into liquid and solid preparation two types, liquid preparation dispersible oil-suspending agent,
Cream, aqueous emulsion, microemulsion；Solid preparation has wettable powder, soluble powder, water dispersible granules.
The defect that existing chemical insecticide exists is as follows:
(1) existing insecticide, just for the insect pest in planting site, not notable or the most anti-to the diseases control in planting site
Effect, and existing insecticide is the most obvious to certain insect insecticidal effect；
(2), when existing insecticide is applied to Semen Maydis pest control, Semen Maydis is had certain side effect, poor stability, it is grown
There is certain inhibitory action, and then reduce crop yield.
Summary of the invention
The present invention solves the deficiency that prior art exists, it is provided that a kind of salt-soda soil Semen Maydis containing Rhizoma Pinelliae extract is special plants
