Description
Technical field
The present invention relates to modern agriculture crop-planting technical field, in particular to a kind of seed soaking side for improving paddy rice anti contravariance
Method.
Background technique
The resistance of plant refers to the certain characters for the resistance adverse environment that plant has；Such as cold-resistant, drought resisting, salt resistance resists
Pest and disease damage etc..The excellent degeneration-resistant character that a kind of plant of nature occurs, is hardly transferred to other kinds of under the conditions of nature
In plant, it is primarily due between not kindred plant that there is reproduction isolation.
After plant is forced, some lethal by injury, although other physiological activity is influenced to different extents,
But they can be survived.If lived in this stressful environmental for a long time, by natural selection, beneficial traits are retained
Come, and constantly reinforce, unfavorable character is constantly eliminated.In this way, the varying environment item in plant long-term evolution and adaptation process
Growing plants just will form the adaptability to certain environmental factors under part, and different modes can be taken to go to resist the various sides of body
Compel the factor.Resist abilities of the plant to various stress (or adverse circumstance) factors, referred to as resistance (stress resistance),
Abbreviation resistance.
Soil salt can cause salt damage to plant when excessive.Under normal circumstances, when soil salt content is more than 0.20%~
When 0.25%, salt stress will be caused.Salt stress is divided into 2 classes to the harmful effect of plant: one kind is salt ion itself to plant
Murder by poisoning, including the destruction to plasma membrane and to the interference of metabolism；Another kind of is 2 kinds of secondary toxic actions that salt ion causes, and is seeped
Stress and nutritional deficiency stress thoroughly.
Rice is annual gramineae plant.Rice is divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous rice.
Claim rice or rice after the tied grain of rice decladding of rice.Rice can also make wine in addition to edible, refine sugar and make the raw material of industry, rice husk, water
Rice straw also has many use.
Rice belongs to grass family Oryza, is an extremely ancient crop.Seed needs enough water from suspend mode to rudiment
Divide, the air of humidity appropriate and abundance.For seed when dry, water content is low, and cellular plasm is in gel state, metabolic activity
It is very faint.
Only moisture abundance when, kind skin expansion softening just can make oxygen soluble in water, penetrate into moisture absorption kind careful
The respiration intracellular that embryo and endosperm could be enhanced.Plasm also becomes solution from gel with the increase of moisture, and Free water increases,
Metabolism is reinforced, and the complicated insoluble substance stored in endosperm is made to be changed into simple solable matter under a series of enzyme effects
For immature organ growth.
Have moisture be also convenient for plumule that organic substance is transported to rapidly in growth, go in radicle to accelerate germination into
Journey.So how can preferably soak seed be to carry out vernalization work important link.Due to the work of enzyme after hybrid rice water suction
Property is stronger, therefore the seed soaking time of hybrid rice seeds is longer than the seed soaking time of conventional rice.
Seed soaking is a Xiang Liucheng of agricultural planting, refers to for the slower seed that germinates, is needed before planting to seed
It soaks seed, the purpose of seed soaking is that seed is promoted more early to germinate, and can also kill some worm's ovums and virus.
The purpose of seed soaking is that rice is made to absorb water quickly, reaches the water content that can normally germinate.Dry rice paddy seed contains
Water rate is usually 15% hereinafter, physiological activity is very faint, in a dormant state.After neutron absorption moisture, kind skin expansion softening,
The oxygen being dissolved in water enters cell with moisture, and the enzyme in seed also starts to activate.Due to the effect of enzyme, the breathing of embryo is made
With enhancing, the insoluble substance of endosperm storage is also gradually converted into solable matter, and with moisture conveying to embryo portion.
Rice embryo obtains moisture, energy and nutriment, and at suitable temperature and Oxygen Condition, cell just starts
Division, elongation, break through glume (germination).As it can be seen that sprout seed it may first have to it be made to suction moisture.But, rice paddy seed
It is not to have water that can germinate, it, which must at least be absorbed, is equivalent to the moisture of own wt 15-18% and could start to germinate.Water suction
Amount could normally germinate when reaching own wt 40%.
Husk thickness, the permeability of time and rice paddy seed required for soaking seed are strong and weak, soak seed before seed water content and
The water temperature of seed soaking etc. is related.Long-grained nonglutinous rice water suction is very fast, and japonica rice water suction is slower；The low water suction of seed moisture content is very fast, and high is relatively slow；Temperature
Spend high very fast, low relatively slow of temperature.Whether seed, which suctions moisture, to judge from the appearance.The seed of moisture is suctioned in semi-transparent
Bright state can indistinctly distinguish embryo and endosperm through husk, and embryo expands protrusion, and endosperm softens, and stripping out husk hand can be the grain of rice
It pulverizes, without clickly sound when fractureing.
The problem of paddy rice anti contravariance can be needed to pay attention in Rice Cropping, due to from different places, many places more rings
Border is different, this brings influence to the plantation of rice, before rice growing can by carrying out certain processing to seed, thus
The resistance for improving rice, promotes the growth performance of Later Stage of Rice.
