Abstract
The invention provides a preparation method for a potato seed dressing agent. The preparation method has the following advantages: 1, the method prepares a bioactive extract through microwave-assisted secondary crushing, synergistic extraction of three algae active components by using an enzyme hydrolysis method, and double-strain liquid co-fermentation, wherein the bioactive extract is rich in bioactive components like natural organic matters, nitrogen-phosphorus-potassium, active strains, algae polysaccharide and mannitol, so nutrients and effective bioactive bacteria are directly provided for the cutting wound surface of the potato, and cutting wound healing is greatly promoted; 2, the seed dressing agent has a film forming characteristic and acts on the surface layer of seed potato to form a natural bioactive protective film which provides protection for the seed potato in the stages of sowing to germination and is naturally-degradable and residue-free; and 3, an application method for the seed dressing agent comprises liquid spraying or seed dressing, and compared with a traditional seed dressing way, the method has the advantages of safety, environmental protection, simplicity, high efficiency, convenient operation, and conservation of effort and labor.
Description
Technical field
The preparation method that the present invention relates to a kind of potato seed-dressing agent, belongs to biologic product technology field.
Background technology
Rhizoma Solani tuber osi (formal name used at school: Solanumtuberosum), belongs to Solanaceae herbaceos perennial, and tuber can be edible, is the fourth-largest important cereal crops in the whole world, is only second to Semen Tritici aestivi, Oryza glutinosa and Semen Maydis, simultaneously the fourth-largest cereal crops of Ye Shi China.
2010, the world wide production of Rhizoma Solani tuber osi reached 3.24 hundred million tons, and China is the first in the world yield big country, and potato yield reaches 75,000,000 tons then.The main producing region of potatoes is Southwest Mountainous Areas, northwest, the Inner Mongol and the Northeast.Compared with Semen Tritici aestivi, Semen Maydis, Oryza sativa L., potato full-powder storage time is longer, can store at normal temperatures more than 15 years, and some countries are classified as Rhizoma Solani tuber osi as strategic reserves grain.2015, China will start Rhizoma Solani tuber osi staple food grainization strategy, advance and Potato ring rot bacteria be become the staple foods such as steamed bread, noodles, rice flour, and the another staple food grain that Rhizoma Solani tuber osi will become outside rice, Semen Tritici aestivi, Semen Maydis has important strategic importance.
In potato culture process, often occur that plant diminishes year by year, leaf-shrinkage is curling, leaf colour shading is uneven, short and small thin and delicate, the tuber deformation be full of cracks of stem stalk, yield descend degradation phenomenon year by year, showing that Rhizoma Solani tuber osi has occurred and that degeneration, it is cause the main cause that yield reduces and commodity property is deteriorated that potato seed is degenerated.Research potato seed degeneration Crack cause, finds and solves potato degeneration technology, be once an important topic of world research Rhizoma Solani tuber osi.Research worker from plant physiology, biochemistry, cultivation technique, kind block processes, pest and disease damage such as infects at the aspect, potato degeneration is conducted in-depth research, finally specify that virus infect and in potato block, accumulation is the main cause of potato degeneration, Common Diseases has late blight in seedling stage, tar spot, dry rot.Potato block as lower generation " seed " suffers virus infection and accumulation because of reasons such as handling, transport, storage, potato seed strippings and slicings, and not there is the mechanism of self purged body inner virus, cause that plant virosis increases the weight of year by year, make plant can not give full play to the industry characteristics of kind in process of production, cause Severe Reduction.Only adopt modern biotechnology the virus in potato seed to be removed, recover physiological function and the industry characteristics of Potato Cultivars itself, just can prevent the degeneration of Rhizoma Solani tuber osi, make up to commodity property and the yield of kind.
For the infringement preventing virus infection potato seed potato block from potato growth being caused, common method is to utilize seed dressing that potato block is dressed seed, conventional seed dressing has the violent zinc of plant ash, streptomycin, metalaxyl, Mancozeb, carbendazim, Sandofan etc., dressed seed by various compatible combination, complicated operation, easily bring secondary virus infection, and the use of its agricultural chemicals is likely in plant to be enriched with, human body is adversely affected.Development of new safety, environmental protection, novel agricultural potato seed-dressing agent easy and simple to handle have become as the task of top priority.
Summary of the invention
For making up existing potato seed-dressing agent deficiency in actual production operates, the invention provides a kind of liquid potato seed-dressing agent, it is therefore intended that alleviate potato seed potato block virus infection, it is ensured that potato plant normal growth, improve plant resistance, improve yield；Walk quickly and keep away subterranean pest-insect simultaneously, prevent soil-borne disease, resist peasant household and plant the continuous cropping disease that Rhizoma Solani tuber osi is caused throughout the year.
For achieving the above object, the technical solution used in the present invention is as follows:
The invention provides a kind of liquid potato seed-dressing agent, it is characterised in that: raw material and the proportion of composing of the lixiviating solution of one of seed dressing component are as follows: 10～25 parts of Thallus Laminariae (Thallus Eckloniae), ulva 8～15 parts, Alga Sgrgassi Enerves 15～20 parts, corn straw 20～35 parts, dry rice straw 3～8 parts, plant ash 5～10 parts, glucose 10～15 parts, the peat composed of rotten mosses 5～10 parts, molasses fermented liquid 8～12 parts, soybean cake 10～12 parts, yeast powder 5～8 parts, cellulase 3～5 parts, pectase 2～3 parts.
The preparation method that the invention provides a kind of liquid potato seed-dressing agent, it is characterised in that: above-mentioned raw materials prepares the lixiviating solution preparation for potato seed-dressing agent by " microwave-assisted second-time breakage+enzymatic isolation method three Sargassum active component collaborative lixiviate+two microorganisms liquid ferment altogether ".
Above-mentioned lixiviating solution production technology, realizes particular by following approach:
