Description
Technical field
The invention belongs to field of agricultural cultivation, and in particular to a kind of rice seedling-growth soil regulator and preparation method thereof.
Background technique
Rice is to like sour crop, and suitable pH value is 4.5 ~ 5.5, and acidic environment can effectively facilitate the plant of growth of seedling stage
The development of strain is played the role of improving seedling quality, enhancing resistance, root system development and strong sprout is promoted to keep a full stand of seedings.Rice seedling-growth soil regulator
Various bacterium in soil are mainly killed with pesticide-clay mixture method in the 1980s, start the 1990s to increase nutritional ingredient and
Adjust acid substance.Present rice seedling-growth soil regulator is a kind of preparation for effectively facilitating rice seedling development, it is according to the physiology and ecology of rice
Characteristic integrates disinfection, increasing acid, nourishes, changes control, and disinfectant, chemical control agent, the sour agent of increasing, nutritional agents act on each other, and effect is mutual
It mends, comprehensive function, the suitable growing environment of rice seedling is created, to achieve the purpose that strong seedling.
Rice seedling-growth soil regulator is according to rice shoot physiological status, ecological characteristics and existence regional soil fertility in Rice Seedling Culture Under Dry Condition environment
Property, the suitable nutrient environment of building rice growth, to achieve the purpose that seedling is strengthened in diseases prevention.Rice seedling-growth soil regulator includes four kinds of preparations
Ingredient: disinfectant, chemical control agent increase sour agent, nutritional agents.Result of study shows that strong seedling agent can effectively facilitate seed endosperm conversion
Rate, chlorophyll content, soluble sugar content and dry-matter accumulation.
Strong seedling agent is mostly used on seedling cultivation of rice, form is relatively simple, has using crop species mainly based on solid-state at present
There is limitation, future can develop the multi-forms product such as aqua, granule, it is made to be widely used in field-crop, thus full
Sufficient agricultural development needs.The development of the future of agriculture will be green, Up Economy Agriculture, and strong seedling agent should also walk the road of economical environment-protective,
It finds green bio resource and integrates the prior art, innovation research and development organic materials economizing type strengthens seedling agent, final to realize that agricultural be held
Supervention exhibition.
Cultivating strong seedling is the basis that rice obtains high yield, and the non-irrigated critical issue for educating strong seedling is tune acid and the disinfection of bed soil.
The suction acid vectors of traditional rice seedling-growth soil regulator generally use what furfural dregs, turf, flyash, dry rice husk etc. had a single function in production
Material cannot give full play to efficient sterilizing efficiency in the above-mentioned carrier material of the microbial bacteria of addition, while there is also absorption fertility
The problems such as difference adjusts the sour duration short, and middle microelement need to be supplemented additionally.Rice in north china needs to carry out canopy in the cold time in early spring
Film seedling, rice shoot is usually endangered by microthermal climate in germination of rice, emergence, growth course, and it is withered that damping-off, blueness easily occurs
Disease and yellow seedling diseases.The influence of weather and disease to rice shoot can be mitigated using strong seedling agent.
Strong seedling agent used at present is mainly by the acidulants and rice seedling nutrition of the absorption concentrated sulfuric acid such as flyash, lignite, rice husk
Element, sterilizing pesticide composition；Wherein acidulants dosage is big, accounts for 65% or more, and nutritive element content is then relatively fewer, right
The germination percentage and emergence rate of seed without be obviously promoted effect.The unit consumption of strong seedling agent is big at present, about 150 ~ 600g/
m2, not only high production cost, but also increase the labor intensity of transportation cost and fertilising.Strong seedling agent needs first that this is several when using
Kind of ingredient is mixed with 5 ~ 6 times of fine earths by screening again after mixing to be mixed even, is made into Nutrition Soil, then Nutrition Soil is uniformly sprinkling upon and has been put down
It in whole good seedbed, flattens, pour bottom water, water can just be sowed after seeping, time-consuming.
