Description

A kind of multifunctional composite seed coating agent

Technical field

The present invention relates to a kind of preparation for the crop seed processing, specifically a kind of kind clothing agent of suitable paddy rice use, it is with agricultural chemicals, fertilizer, plant growth regulator isoreactivity composition, the crop seed inorganic agent that the non-active ingredients such as film forming agent, emulsifier, dispersant, antifreezing agent, defoamer, preservative, pH value conditioning agent, colorant mix.

Background technology

The growth of crop in natural world always all can not be very smooth or easily success with growing, and it can run into invasion and attack and the destruction of various damage by disease and insect etc., causes crop not grow normally and growth.Can cause death when serious and die, particularly in seedling stage, a little less than the crop disease-resistant worm ability, it is especially important that the effectively preventing seedling stage diseases and pests just seems.Traditional method is to adopt the seed disinfection method such as dressing seed, seed soaking and soil disinfection method to prevent and treat the damage by disease and insect of crops seedling stage, although these methods have certain effect, effect is not very desirable.Adopt method for soaking seed that medicament is diluted in the water, dosage is large, and waste is many, adopts dressing seed easily to cause seed dressing inhomogeneous, or causes kind of a daughter lesion.It is the poor adhesive force of medicament on seed that these methods have a common shortcoming, Habitat or easily come off when after planting meeting water, and the lasting period is short, and dosing is large.Seed disinfection is carried out in the short time prior to seeding, is difficult to realize the seed treatment industrialization.The soil disinfection dosing is large, and cost is high, and time-consuming, environmental pollution is serious.

The agent of kind of clothing is for seed pelleting, a class preparation with film forming characteristics.Plant the clothing agent and can make the breeding standardization, have again the several functions such as plant protection effect.The dressing function of planting the clothing agent is mainly manifested in following three aspects: the one, and the harm of prevention disease in seedling stage, worm, mouse reduces dosage and medication number of times, is conducive to protect pest natural enemy, protection of the environment.The 2nd, the part in kind of the clothing agent (such as little fertilizer) can have additional nutrients to seed, guarantees full stand, shape seedling, improves seedling quality.The 3rd, promote and the standardization of guarantee breeding, commercialization and socialization.

At present, the development and production technology of dry crop (comprising paddy drought seedling) kind clothing agent is fairly perfect, and in application, obtained reasonable effect, but the kind clothing agent of paddy rice, particularly seed soaking are with dressing agent for rice large breakthrough not being arranged still with live under water.Main cause is that the seed soaking seedling of paddy rice and field production mode are different from growing seedlings of dry crop and planting type.Dressing agent for rice to filmogen in water dissolubility and the requirement of corresponding film forming slow release method far above the agent of dry crop kind clothing, require film forming agent to be insoluble in water under water at rice seed soaking with when live, active component can slowly discharge in the clothing film, in the Seed Germination of Rice process of growth, be difficult for running off, and require that film forming agent will be breathed freely, good water permeability, guarantee that seed can absorb the required oxygen of normal germination and growth and moisture.

Chinese patent discloses the relevant technologies of relevant dressing agent for rice, and what relate to such as the CN1102944A patent publication is the agent of rice direct-seeding kind clothing, but requires seed to select presoaking and germinating, carries out dressing again, and capsuled seed can't be stored, and is difficult to realize the seed treatment industrialization.What the CN1117343A patent publication related to also is paddy rice seed coating agent, but used film forming agent is polyacrylamide soluble in water, and the clothing film is very easily water-soluble and cause active component to lose in a large number during seed soaking.

Summary of the invention

Purpose of the present invention is exactly the above-mentioned deficiency for prior art, adapt to each veriety and can carry out the dressing agent for rice that presoaking and germinating can be not destroyed for different regions, different soil, various seasons provide a kind of, effective prevention and control seedling stage diseases and pests, and can urge the control growth of seedling, guarantee that seedling is neat, strong, it is many to tiller, and percentage establishment of seedling obviously improves.Capsuled seed can adopt conventional method running water presoaking and germinating, carries out that water is educated, drought is educated or live.Capsuled seed can safe storage.
