Description
Technical field
The present invention relates to the composite fertilizer field, the special-purpose slow release fertilizer for water-retention sprout-cultivation of using during as base manure or preparation nutrition soil when especially relating to and a kind ofly being used for paddy drought seedling, moulding plate seedling raising and dry crop and growing seedlings.
Background technology
Along with rice such as rice shoot with rsgun and wide planting, dry-raised and casttransplanted rice, machine rice transplantation do the development of light cultivation, paddy rice upland nursery and machine transplanting of rice disc type seedling growing mode are widely used, but there are following technological difficulties in these two kinds of seedling raising mannerses:
Dry seedling bed of rice mode technological difficulties are: the one, and the complex procedures of fostering and apply fertilizer; The 2nd, diseases such as bakanae disease, damping-off easily take place; The 3rd, soil moisture supply buffering amplitude is little, easily causes the blue or green withered seedling of physiology.
Machine transplanting of rice disc type seedling growing mode technological difficulties are: except that the problems referred to above, reduce the amount of broadcasting for machine transplanting of rice disc type seedling growing and should not coordinate with enhancing packing dynamics, cause the amount of broadcasting bigger than normal, seedling age elasticity is little, and the rice shoot reguarity is poor.
At above-mentioned technological difficulties, since the eighties in last century, many units have developed products such as rice nursery sock growing seedling strengthen agent, special fertilizer for seedling culture, 00110318.0), the anti salt and alkali paddy rice seedling strengthening fertilizer of the Suihua City Wu the lady in the moon of the Heilongjiang Province China development (patent No.: 02132783.1), the Fertilizer special for raising rice seedlings (patent No.: 02152332.0) etc. of the Wang Hong of Ningxia Hui Autonomous Region celebrating development the rice nursery sock growing seedling strengthen agent of being developed as academy of agricultural sciences, Liaoning crop (patent No.:, the said products is at particular locality performance prophylaxis effect in strong sprout, but the shortage general applicability, as:
1, the said products lacks retaining, water retaining function, and under the upland nursery situation, soil moisture supply buffering amplitude is little, and the blue or green withered seedling of physiology easily takes place.
2, the said products lacks insecticidal function, can not prevent and treat non-irrigated seedling raising subterranean pest-insect and seedling stage insect.
3, the said products zinc, iron content deficiency, and China most of rice district, soil zinc deficiency, iron deficiency are serious, cause red seedling, Huang Miao, stiff seedling and seedling extremely.
4, the said products lacks promoter, can not promote the rice shoot root system development effectively, solves machine transplanting of rice disc type seedling growing and reduces the amount of broadcasting and the coordination that strengthens the packing dynamics, causes that application rate is excessive, seedling age elasticity is little.
5, the said products lacks dwarfing agent, can not solve under the long length of time rice seedlings grow condition, and seedling growth is scurried high problem, and is under hot and humid condition, more outstanding.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art products, increase retaining water conservation, short root growth, downgrade functions such as rice shoot, kill pests, and augment trace elements such as zinc, iron, improve the universality and the practicality of Fertilizer special for raising rice seedlings, be developed into the novel special fertilizer for raising rice seedlings that possesses multiple function.
The objective of the invention is to be achieved through the following technical solutions:
A kind of special-purpose slow release fertilizer for water-retention sprout-cultivation is characterized in that this special use fertilizer is to be formed by High hydrophilous resin, nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, zinc fertilizer, iron fertilizer, boron fertilizer, fertiliser containing magnesium, molydbenum fertilizer, manganese fertilizer, copper fertilizer, sterilant, sterilant, promoter, dwarfing agent and sorbent material mixing.The effective constituent that contains following ratio in the mixture that is obtained: High hydrophilous resin 5-10%, nitrogen (N) 8-20%, Vanadium Pentoxide in FLAKES (P
2O
5) 5-12%, potassium oxide (K
2O) 3-7%, zinc (Zn) 1-3%, iron (Fe) 1-3%, boron, magnesium, molybdenum, manganese, the fertile 1-5% of copper, sterilant 0.2-2%, sterilant 0.1-2%, promoter 0.001-0.01%, dwarfing agent 0.001-0.01%, surplus is a sorbent material.
Described High hydrophilous resin is agricultural type vinylformic acid sodium salt cross-linked polymer (for example Rugao, Jiangsu Province section power chemical plant produces), also can adopt other agricultural type water-absorbing resin;
