Description
Technical field
Special fertilizer for dry seedlings of paddy rice of the present invention relates to a kind of fertilizer, and that uses on particularly a kind of medium for dry breeding of seedling bed of rice is special-purpose fertile, claims again " non-irrigated seedling green grass or young crops ".
Background technology
Paddy drought seedling is an advanced person's promoting in China big area over past ten years a agrotechnique, for increase output, reducing cost has tangible effect.Paddy drought seedling has very big difference to the requirement and the water seedling of soil and fertilizer, and the peasant is difficult to be grasped, and has influenced the popularization of non-irrigated seedling-cultivation technique to a certain extent.Therefore, the peasant is badly in need of wanting a kind of be suitable for using on the medium for dry breeding of seedling bed of rice special-purpose fertile at present.
Summary of the invention
The objective of the invention is provides a kind of special fertilizer for dry seedlings of paddy rice at above-mentioned weak point, is a kind of be suitable for using on the medium for dry breeding of seedling bed of rice special-purpose fertile.
Special fertilizer for dry seedlings of paddy rice takes following scheme to realize:
Special fertilizer for dry seedlings of paddy rice is to be formed by the proportioning mixing by nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, sulphur, furans pellet, paclobutrazol, and its raw material weight per distribution ratio is:
Nitrogenous fertilizer 30～50%
Phosphate fertilizer 15～45%
Potash fertilizer 10～32%
Sulphur 6～12%
Furans pellet 0.01～0.02%
Paclobutrazol 0.1～0.2%
Wherein nitrogenous fertilizer is selected a kind of or mixture in ammonium sulfate or the ammonium chloride for use; Phosphate fertilizer is selected a kind of or mixture in monoammonium phosphate, diammonium phosphate, the calcium superphosphate for use; Potash fertilizer is selected vitriolate of tartar for use.
Above-mentioned special fertilizer for dry seedlings of paddy rice contains effective total nutrient 25～50%, wherein nitrogenous (N) 10～22%, Vanadium Pentoxide in FLAKES (P
2O
5) 7～20%, potassium oxide (K
2O) 5～16%.
By said ratio raw materials weighing nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, sulphur, furans pellet, paclobutrazol, then raw material is mixed, pulverizes, put into agitator and stir, promptly make special fertilizer for dry seedlings of paddy rice.
Special fertilizer for dry seedlings of paddy rice of the present invention has following advantage:
1, can satisfy the demand of dry seedlings of paddy rice whole process to several principal element nitrogen, phosphorus, potassium.According to test, special fertilizer for dry seedlings of paddy rice of the present invention (non-irrigated seedling green grass or young crops) is no matter be applied in low still high infertile field of fertilizing the soil, can both obviously promote seedling growth, as on the not high yellowish-white native seedbed of fertility every square metre use 52 grams and 125 respectively and restrain special fertilizer for dry seedlings of paddy rice (non-irrigated seedling green grass or young crops), the japonica rice seedling does not increase by 90% and 287% than there being fertile the processing respectively in 6 leaf phases hundred seedling dry weight rates, on become silted up native seedbed in the high vegetable garden of fertility level, use 52 gram special fertilizer for dry seedlings of paddy rice of the present invention (non-irrigated seedling green grass or young crops) for every square metre, the long-grained nonglutinous rice seedling does not increase by 16% in 6.3 leaf phases hundred seedling dry weight rates than there being fertile the processing, therefore, under general soil fertility condition, use a certain amount of special-purpose fertilizer, can no longer use other chemical fertilizer.
2, nitrogenous fertilizer, phosphate fertilizer and the potash fertilizer raw material selected for use of special fertilizer for dry seedlings of paddy rice of the present invention (non-irrigated seedling green grass or young crops) all is acid fertilizer or physiological acidity fertilizer, and added part acidity regulator sulphur, therefore has good soil acid adjustment function.According to test, use special fertilizer for dry seedlings of paddy rice (non-irrigated seedling green grass or young crops) 100-150 gram for every square metre, can make soil acidity reduce 0.5-1.1 pH value unit.Generally can make the requirement of the suitable dry seedlings of paddy rice of soil pH value, improve the edatope nutrient situation, thereby have the effect of prevention rice shoot physiological disease, promote the seedling growth growth, alleviate the generation of dead mu and weak seedling, guarantee the growth of strong seedling.
3, special fertilizer for dry seedlings of paddy rice of the present invention (non-irrigated seedling green grass or young crops) is added with insecticide carbofuran composition furans pellet, can effectively prevent and treat the main insect pest of non-irrigated seedling.
4, special fertilizer for dry seedlings of paddy rice of the present invention (non-irrigated seedling green grass or young crops) is added with and impels the short strong composition paclobutrazol of non-irrigated seedling, can promote form the strong sprout of non-irrigated seedling.

Special fertilizer for dry seedlings of paddy rice is the experiment and demonstration effect in Nanjing following (seeing the following form 1):
1, improves seedling rate and seedling rate.The seedling rate of using special fertilizer for dry seedlings of paddy rice " non-irrigated seedling green grass or young crops " does not have fertile the processing increases great majority between 1～8 percentage point, on average increases 2 percentage points; Using fertile processing of common compound increases by 1.5～6 percentage points, on average increases 3 percentage points.The seedling rate of using non-irrigated seedling green grass or young crops does not have the fertilizer processing and increases average 6 percentage points, and more common compound fertilizer is handled 3 percentage points of average increases.
2, accelerate developmental process, improve leaf age.Using special fertilizer for dry seedlings of paddy rice " non-irrigated seedling green grass or young crops " does not on average increase by 0.4 than there being fertilizer processing leaf age, uses 0.2 of the average increase of the fertile processing of common compound.
3, increase individual plant band tiller number.Use the fertile individual plant band tiller number of handling of the blue or green nothing of non-irrigated seedling and on average increase 0.6, use fertile processing of common compound and on average increase 0.5.
4, increase dry-matter accumulation, improve dry matter.Use the hundred seedling dry weights of non-irrigated seedling green grass or young crops, do not have fertile the processing and on average increase 48%, use fertile processing of common compound and on average increase 18%.
5, increase reduces insect pest to the restraining effect of underground insect.For example do not have fertile handle and execute common compound fertile handle to compare before back subterranean pest-insect number and the examination remain basically stable or improve, and the subterranean pest-insect number of using the blue or green processing of non-irrigated seedling has minimizing in various degree.
