Abstract
The present invention relates to a special-purpose fertilizer for growing upland rice seedling. It is an organic and inorganic type multifunctional special-purpose fertilizer. Said invention uses general N, P, K ternary compound fertilizer, trace element salts, antiseptics, pesticide, plant growth regulator ABT and leonardite as raw materials, after the leonardite is air-dried and pulverized, the pulverized leonardite and other ingredients are mixed according to a certain proportion so as to obtain the invented solid powdery fertilizer.
Description
It is multi-functional special-purpose fertile to the present invention relates to a kind of organic-inorganic, fertilizer for dry sprout cultivation of paddy rice.
At present, the paddy drought seedling cultivation technique is that rice by Japan does expert Yuan Zheng Mr. city through the concentrating on studies of many decades, and compares with conventional seedling-cultivation technique, have water saving, save recruitment, save mother field for seedling, save advantages such as seed, seedling expense and raising output.But this technology is in actual promoting the use, to add inorganic nitrogen, phosphorus, potash fertilizer with farm crop tangerine bar or slag fertilizer before not only going into the winter, mix and impose in the soil, carry out improvement of soil fertility, also will regulate soil acidity with sulfur flour spring, P in soil H value is reduced to below 6.5, simultaneously, also will be with the sterilization agricultural chemicals to the soil disinfection sterilization.Therefore, cause the nursery soil overlong time of fostering and apply fertilizer, use the fertilizer difficulty of becoming thoroughly decomposed, acid adjustment is slow, and weak effect, the seedling production link is many, and production operation program complexity is loaded down with trivial details, the seedling expense is higher, labour intensity is big, and the peasant is difficult to grasp accurately, and the seedling quality that brings out is poor, the advantage of drought seedling-cultivation technique is not in full use, and has influenced promoting the use of this technology.
The objective of the invention is to: invent a kind of improvement of soil fertility, acid adjustment, sterilization, cold-resistant fertilizer for dry sprout cultivation of paddy rice of integrating, to reduce non-irrigated seedling production link, make easy and simple to handle, be easy to grasp, and improve non-irrigated seedling seedling quality, reduce non-irrigated seedling cost, help promoting the use of non-irrigated seedling-cultivation technique.
The present invention realizes its purpose like this: this special use fertilizer is with common N, P, K three element fertilizers, the trace element salt, sterilizing agent, insecticide, plant-growth regulator ABT, weathered coal is a raw material, weathered coal is air-dry, pulverize after, make solid-state powdered fertilizer with other raw materials by the proportioning mixing and stirring.
The present invention also can realize its purpose like this: fertile used raw material and the weight percent proportioning thereof of this special use is:

By above-mentioned test, this special use fertilizer was used for non-irrigated seedling test in 2 years in 1998-1999, tested nearly ten thousand mu, and this special use fertilizer has following characteristics:
1, the present invention fills a prescription rationally, organic and inorganic fertilizer, medicament, growth regulator, trace element etc. are integrally combined, be that a kind of organic and inorganic type is multi-functional special-purpose fertile, promptly, be furnished with N, P, K element fertilizer, used weathered coal in addition according to the rice shoot needs in seedling stage, contain a large amount of humic acid, improved the redox potential of soil, increased the chlorination reductase enzyme, soil supplying nutrient capability is increased.
2, added organic acid (humic acid) growth regulator and trace element components in the special-purpose fertilizer, improved the rice shoot anti-adversity ability, cold-resistant drought-resistant ability is stronger.
3, be added with disinfectant, sterilant in the special-purpose fertilizer, can have reduced seedling stage diseases and pests the nursery soil disinfection.
4, raw material is based on acidity, and adds nitric acid and make blender, improved soil acid adjustment ability.
Above-mentioned owing to having, compare with the non-irrigated seedling of routine, have following function and effect:
1. can finely satisfy the rice seedling nutritional need, improve seedling quality, the seedling growth stalwartness, The leaf look dark green, and no fertilizer is crossed victory, lacked the phenomenon of auxin;
2. can improve emergence rate. Emergence rate improves 12.8-13.56%; Can reduce the seed consumption.
3. percentage establishment of seedling height. Exceed 5.3-7.1% than conventional non-irrigated seedling raising method.
4. rice shoot total quality height. The individual plant tillering ability is strong, manys 0.86-0.98 than the non-irrigated method of raising seedling of routine Individual, the many 21.2-32.3 of 100 strain fresh weights gram, the many 10.9-13.23 grams of 100 strain dry weights, it is many to have a cultivation The strong seedling of tiller and to the effect of rice shoot dry-matter accumulation, because soil disinfection bactericidal action, the anosis worm of rice shoot are arranged Evil takes place, for increasing production of rice is laid a good foundation.
5. strong and rapid to nursery soil acid adjustment ability. Measured, and can make P in soil H rapid in after planting 25 days Drop to 6.0, compare with conventional Cosan acid adjustment, the acid adjustment ability is strong.
6. peasant household is easy to use. Single fertilization gets final product, greatly simplified non-irrigated seedling production routine and Cumbersome operation, easy and simple to handle, be easy to grasp, be conducive to extensively promoting the use of non-irrigated seedling-cultivation technique, and Reduced seedling cost.
