Abstract
The invention discloses a seedling-strengthening agent special for super rice and a using method thereof. The seedling-strengthening agent special for the super rice consists of the following components in part by weight: 50 parts of ammonium sulfate, 10 parts of superphosphate, 19.6 parts of potassium chloride, 20 parts of biological organic fertilizer, 0.2 part of paclobutrazol and 0.2 part of carbendazim. The seedling-strengthening agent can obviously improve the leaf emergence rate of seedlings, reduce the plant height, increase the stem base width, the biomass and the chlorophyll content of the seedlings, obviously improve the protein and proline content of the seedlings, and enhance the activity of phenylalanine ammonia-lyase so as to improve the stress tolerance of the seedlings and fulfill the aim of culturing strong seedlings.
Description
Technical field
The present invention relates to agricultural production, be specifically related to a kind of seedling-strengthening agent special for super rice and using method thereof.
Background technology
Seedling is an important step in the Rice Cropping process, and the quality of seedling quality directly affects rice yield.The quality of seedling quality is not only closely related with the nutritional status of bed soil, and is subjected to the impact of rich water regulation and control in the seedling process.And fertilizer for improving the growth of seedlings is the materialization technology of raising rice seedlings, integrates seedling bed regulating acid, sterilization, rice shoot nutrition and chemical regulation, not only has the advantages such as easy and simple to handle and saving of labor's abridged edition, and more easily cultivates strong seedling.But, existing fertilizer for improving the growth of seedlings function singleness, range of application is narrower, and mainly is to develop for general rice varieties, number is 92106324.5 disclosed a kind of rice seedling-growth soil regulators and 200710072439.5 disclosed raising rice seedlings fertilizer for improving the growth of seedlings and using method such as Chinese patent application.Along with successful cultivation and the large-area Demonstration And Extension of super hybridization rice, the plantation status of super hybridization rice becomes increasingly conspicuous, and it is more important that seedling-strengthening agent special for super rice just seems.
Summary of the invention
The object of the invention is to according to the function singleness that exists in the existing rice seedling-growth soil regulator, can't produce to super hybridization rice the problem of enough effects, a kind of fertilizer for improving the growth of seedlings of super hybridization rice special use is provided.
A further object of the invention is to provide the using method of the fertilizer for improving the growth of seedlings of above-mentioned super hybridization rice special use.
Above-mentioned purpose of the present invention is achieved by the following technical programs:
Seedling-strengthening agent special for super rice of the present invention can be used for non-irrigated seedling and watery ricenursery, contains nitrogen, phosphorus, potassium and fertilizer, also contains sterilant and plant-growth regulator, has the effect that prevents disease and pest and cultivate strong seedling, and is easy and simple to handle, saving of work and time.
As a kind of preferred version, described plant-growth regulator is 15% paclobutrazol, and sterilant is derosal.
As a kind of preferred version, seedling-strengthening agent special for super rice of the present invention is comprised of the component of following by weight percentage ratio meter: ammonium sulfate 50, calcium superphosphate 10, Repone K 19.6, biological organic fertilizer 20, paclobutrazol 0.2 and derosal 0.2.
The using method of seedling-strengthening agent special for super rice of the present invention is with behind fertilizer for improving the growth of seedlings and the abundant mixing of rice seedling bed soil, and sowing gets final product, and need not apply any external source fertilizer in the seedling process.
As a kind of preferred version, above-mentioned fertilizer for improving the growth of seedlings addition in use is 30g/m
2
As a kind of preferred version, the present invention has following beneficial effect:
(1) seedling-strengthening agent special for super rice of the present invention has dwarfing, short root, enlarges afforested area and degeneration-resistant effect, and nutritive element content is high, to the germination of seed with improve adult seedling rate and have obvious promoter action; The unit surface consumption is few, and every square metre is 30g only, thereby has reduced fertilising intensity and cost;
(2) fertilizer for improving the growth of seedlings of the present invention can significantly promote the leaf emergence rate of rice shoot, reduce plant height, the stem foot that increases rice shoot is wide, biomass and chlorophyll content, can also significantly improve protein and the proline content of rice shoot, strengthen PAL activity, thereby improve the anti-adversity ability of rice shoot, reach the purpose of cultivating strong seedling.
Embodiment
Further explain the present invention below in conjunction with embodiment, but embodiment does not do any type of restriction to the present invention.
Embodiment 1
Following component is mixed by proportioning: ammonium sulfate 50%, calcium superphosphate 10%, Repone K 19.6%, biological organic fertilizer 20%, paclobutrazol 0.2% and derosal 0.2%.Small packages with every bag of 1kg is packed, in use, to mould the dish pendulum on the seedling bed, in the work ditch of seedling bed, pour into a small amount of water before the sowing, add 20 gram " super rice fertilizer for improving the growth of seedlings " consumptions by whenever moulding dish, with the creeper dilatory mud that forms back and forth, mould on the dish with spoonful mud being sprinkled, sow after striking off mud.Broadcast the anti-string of rear light pressure seed root, early rice adds membrane covering and gets rid of field accumulated water etc., and late rice is broadcast rear available straw preventing rain wash, guarantees to cultivate strong rice shoot.1 kilogram of the every bag of super rice fertilizer for improving the growth of seedlings can be cultivated 1 mu of land for growing field crops rice shoot.
Embodiment 2 contrast experiments
Tested on March 5th, 2006 and carry out at Agricultural University Of South China agronomy testing ground.Experiment arranges fertilizer for improving the growth of seedlings and processes and 2 factors of method of raising seedling.Fertilizer for improving the growth of seedlings (contrast, conventional seedling) is not executed in the fertilizer for improving the growth of seedlings setting and (Applying Quantity of Seedling Strengthen Agent is 30g/m to execute fertilizer for improving the growth of seedlings
2) two processing; Method of raising seedling arranges non-irrigated seedling and 2 processing of water-raised seedling.Every kind of processing all arranges 3 repetitions, randomized block design, and residential quarter, rice seedling bed area is 10 m
2Take a sample according to pertinent literature in the 3 leaf phases of rice shoot, plant height, the stem foot of measuring rice shoot is wide, biomass and adult seedling rate; Measure chlorophyll, the proline(Pro) (content of Pro and soluble protein of rice shoot blade; Measure the activity of peroxidase (POD), superoxide dismutase (SOD) and the phenylalanine ammonia lyase (PAL) of blade.Experimental data sees Table respectively 1, table 2.
Table 1 fertilizer for improving the growth of seedlings is processed the impact that the super hybridization rice seedling growth is grown
As can be seen from Table 1, for two kinds of seedling raising methods, fertilizer for improving the growth of seedlings can significantly reduce the plant height (dwarfing effect) of rice shoot, increases stem foot wide (promoting the false stem flattening of rice shoot), improves the circularity of rice shoot.And, can significantly improve the adult seedling rate of non-irrigated seedling raising, promote seedling growth, increase the individual plant white root of water-raised seedling rice shoot, strengthen the Root Absorption ability of rice shoot.
Table 2 fertilizer for improving the growth of seedlings is on the impact of super hybridization rice rice shoot Leaf Physiology
As can be seen from Table 2, fertilizer for improving the growth of seedlings is processed the chlorophyll content that can significantly increase rice leaf, improves the photosynthetic capacity of blade; Improve the proline content (Pro) of blade and the activity of phenylalanine ammonia lyase (PAL), strengthen the anti-adversity ability of blade.
