Description
Technical field
The invention belongs to pesticide and fertilizer field, and in particular to a kind of shitosan of the load thiophanate-methyl of Fructus Lycopersici esculenti
Sustained-release micro-spheres fertilizer and preparation method thereof.
Background technology
Fertilizer type and need pesticide variety different that each stage in plant growing process needs, at present
It is general to adopt the basal dressing before soil cultivating, and easily in root generation pest and disease damage in crop germination process, then in soil
The medicated powder of punishment pest and disease damage is inside sowed, not only increases labor intensity, and certain injury is caused to crop root；To jointing, fill
Second trophophase such as slurry also needs to impose fertilizer and pesticide, further increases labor intensity.
Medicine fertilizer is that by a certain percentage formula is mixed for pesticide and fertilizer, the pesticide produced by certain technique and fertilizer
Complexing agent.Two farming activities of dispenser and fertilising are united two into one, labour, time, the energy can not only be saved, even more significantly
Reduce production cost, and reduce the consumption of pesticide and fertilizer, optimal application effect is obtained, so as to for environmental protection, carry
The yield of high plant makes tremendous contribution.
