Description
Technical field
The invention belongs to agricultural chemicals and fertilizer field, and in particular to a kind of shitosan of the load streptomycin sulphate of tomato
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 use the basal dressing before soil cultivating, and pest and disease damage easily is produced in root in crop germination process, then in soil
The medicinal powder of punishment pest and disease damage is inside sowed, not only increases labour intensity, and certain injury is caused to crop root；To jointing, fill
Second growth period such as slurry also needs to impose fertilizer and agricultural chemicals, further increases labour intensity.
Medicine fertilizer is that agricultural chemicals and fertilizer are formulated the agricultural chemicals and fertilizer for mixing, being produced by certain technique by a certain percentage
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 agricultural chemicals and fertilizer, obtain optimal application effect, so as to for environmental protection, carry
The yield of plant high makes tremendous contribution.
