Description

Rice coating agent and preparation method thereof

The present invention relates to agricultural technology field, specifically rice coating agent and preparation method thereof.

Paddy rice is the wider cereal crops of China's area under cultivation, constantly perfect along with the popularization of some high-qualitys, high yielding variety and supporting dry-raising and sparse-planting technology, throwing, pendulum seedling technology, after particularly non-irrigated seedling ground construction project is implemented, the Rice Production level has had large increase, but at present main recommended variety and paddy rice planting technology have been brought into play yield potential substantially, the Rice Production level to be further improved, good footpath must be warded off in addition.

In paddy drought seedling is produced in recent years, to exist seeding quantity excessive always, problems such as seedling quality is low, bakanae disease is serious, affect the normal performance of Rice Production yield potential to a certain extent, at these characteristics, fundamentally improving seedling-cultivation technique, realize non-irrigated purpose of educating strong seedling, will be the another breakthrough on the Rice Production.Producing the method that goes up medicament seed soaking commonly used, vexed kind now handles seed, though can solve the problem of some existence, but the medicament active princlple is single, there is limitation on the effect, be difficult to realize the double action that not only improves rice seedling quality but also prevent and treat the insect pest of seeding stage main diseases, and want proportioning to use, complicated operation does not meet the requirement of seed standardization and industrialization development yet.The paddy rice packaging technique just can head it off a technology, more existing at home and abroad at present seed coating medicines are succeeded in developing, paddy rice seed coating agent as the production of Huaiyin, Jiangsu, solve local drought and educated the problem that strong seedling exists, but, can not solve the problem that exists in the paddy rice plantation of certain areas because of the particularity that weather, agricultural production characteristics and disease take place.And for example Bei Fang seed coating medicine " is protected rich No. 2 " etc., can improve emergence rate, promotes the seedling growth in seedling stage, the seedling target in the short root in incompatible south strong sprout.

The purpose of this invention is to provide a kind of rice coating agent and preparation method thereof, the rice shoot that can solve certain areas drought seeding stage existence is mixed up weak, problems such as tillering capacity is low, bakanae disease, soil insect harm, reach and simplify the seedling program, save fertile water-saving, improve the purpose of seedling quality.

The object of the present invention is achieved like this: coating agent for seed of the present invention is the novel form that is made into high-efficiency water-absorbing resin, bactericide, plant growth regulator etc., be to be the specific granule of carrier with the seed, it is coated on the rapid film-forming of energy on the seed, form kind of a clothing, plant clothing and in soil, meet slowly-releasing sacculus of water imbibition formation.The application of water-absorbing resin, but enrichment nutrient increase the ion exchange of fertilizer, improve the seed fertilizer sucting ability; Application by seed coating medicine of the present invention, prolong the lasting period of medicaments such as agricultural chemicals, strengthen preventive effect, reach effective control with seed dispersal and soilborne disease, improve the granular structure of soil, reduce the medication number of times, reduce the control cost, make the seedling growth stalwartness, well developed root system, strong stress resistance, individual plant band tiller rate increases, and Cheng Miao, percentage establishment of seedling improve.

The concrete technical scheme of seed coating medicine of the present invention is: be made up of following raw materials by weight percent: paclobutrazol 0.15-1.6%, and Shi Baoke 0.3-2.66%, by the high hydroscopic resin 3-35% that sodium carboxymethylcellulose is formed, all the other are auxiliary material.

Above-mentioned rice coating agent can be made pulvis and aqua, and producing according to the following steps of pulvis carried out:

1) getting high hydroscopic resin and auxiliary material in proportion, to be ground to fineness be about 100 orders;

2) after being mixed in proportion, paclobutrazol and Shi Baoke be ground to about 100 orders;

3) with 1) and 2) particulate that makes mixes, behind abundant stirring and evenly mixing, vacuum packaging;

Producing of aqua by poly-carrying out of following step:

1) water-absorbing resin after grinding by 4-6% adds the water of 89-94%, makes it fully be dissolved in water;

2) paclobutrazol and the Shi Baoke after will grinding in proportion is dissolved in the above-mentioned solution, fully adds warning color behind the mixing, packing.

Rice coating agent of the present invention has following good effect compared with the prior art:

1, can simplify the seedling link, improve seedling quality, reduce production costs, increase production efficiency, increase the scientific and technological content of agricultural production, also accelerate the process of agricultural science and technology department simultaneously to industrialized development.

2, can reduce the usage amount of agricultural chemicals significantly, reduce to the pollution of environment with to people and animals' harm.

3, use behind this seed coating medicine rice shoot short strong, leaf look viridescent, seedling quality increases substantially, and output increases.According to test determination, plant height reduces by 1.3 centimetres than obsolete (contrast), 0.1 centimetre/strain of the wide increase of stem foot, the long comparison of root is according to increasing by 0.76 centimetre, and white root increases by 3.2, and band tiller rate increases by 29.8%, and can prevent and treat diseases such as bakanae disease in seedling stage effectively, preventive effect reaches more than 90%.

4, owing to contain the high-efficiency water-absorbing resin, can form water-retention sac, guarantee that the rice shoot root supplies water, and has tangible drought resistance function at the seeding stage root.

Embodiment 1:

1) to be ground to fineness be about 100 orders for the high hydroscopic resin 30% that will be made up of carboxymethyl cellulose and auxiliary material kaolin;

2) after being mixed, the Shi Baoke of 0.218% paclobutrazol and 0.5% is ground to about 100 orders;

3) with 1) and 2) particulate that makes mixes, after fully mixing, vacuum packaging.

Embodiment 2:

Producing of aqua by poly-carrying out of following step:

1) getting the high hydroscopic resin of being made up of sodium carboxymethylcellulose 4%, to be ground to fineness be about 100 orders;

2) water-absorbing resin after will grinding adds in 90.6% the water, makes it fully be dissolved in water;

3) paclobutrazol 1.4% and Shi Baoke 0.7% are added in the above-mentioned solution; Fully add warning color behind the mixing, packing.

Using method: bag farming agent of the present invention is at non-irrigated seedling, and easy easy and simple to handle is adopted and done kind of a direct sowing method, soaks quantitative seed about 24 hours in clear water earlier; Pull seed-grain out pouring and remove excessive moisture, the aqua seed coating medicine with before shaking up, add the group's of rolling dressing in the round bottom containers such as placing basin in the kind, make seed coating medicine be adsorbed on the surface of the seed equably, or bud kind Bao Nong (clear water immersion seed-grain 24 hours, pull the seed-grain pouring out and remove excessive moisture, seal and plant, add seed coating medicine, the group's of rolling dressing in batches to showing money or valuables one carries unintentionally, make seed coating medicine evenly invest the surface of the seed), can sow; The consumption that aqua is pressed 150ml seed coating medicine maize kind 4-5 kilogram uses.After planting mud is gone in the slight suppression of seed, 1 centimetre of blinding is eliminated the back epiphragma before the bud; Epiphragma 5-7 days backsight seedbed soil moistures content are watered once, wait to emerge and take off the film hardening at 90% o'clock, and other measure is consistent with the specification requirement of seedling in fertile and dry seedbed seedling.
