Description
Technical field
The invention belongs to pesticide and fertilizer field, and in particular to a kind of chitosan sustained-release of the load tetracycline of Fructus Lycopersici esculenti
Microsphere 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 pest and disease damage is produced in root in crop germination process, then in soil
The medicated powder of punishment pest and disease damage is inside sowed, is not only increased labor intensity, and is caused certain injury to crop root；To jointing, filling
Second trophophase such as slurry also needs to impose fertilizer and pesticide, further increases labor intensity.
Medicine fertilizer is that formula is mixed by a certain percentage 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, obtain optimal application effect, so as to for environmental protection, carry
The yield of high plant makes tremendous contribution.
