Description
Technical field
The present invention relates to a plant growth regulators, the anti-low temperature of particularly a kind of paddy rice expansion fringe resistant to lodging increases a yield-increasing modifying agent.
Background technology
Paddy rice is the main cereal crops of China, and rice is the staple food of China's 65% above population.Since the establishment of the nation 60 in the period of, China's Rice Production is greatly developed, cultivated area rises to 3,140 ten thousand hm2 by 2,540 ten thousand hm2, per unit area yield rises to 6.3t/hm2 by 1.9t/hm2, gross output rises to 200,000,000 t by 4,864 ten thousand t, the average proportions that the paddy cultivated area accounts for foodstuff planting area is 28.3%, and gross output has accounted for about 40% of cereal crops gross outputs, and gross output accounts for the first in the world.
At present, long-term cultivated area 3,000 ten thousand hm2 of China paddy rice, the long-term cultivated area of its intermediate keng rice is 7,300,000 hm2, accounts for 25.5% of paddy rice total cultivated area; About 5190.3 ten thousand tons of gross yield.Polished rice particularly " northeast rice " then is main " grain ration " kind that China people like food.In the north and coastal large-and-medium size cities, polished rice pouplarity and market prospects are much larger than long-grained nonglutinous rice, and along with the raising of economic development and living standards of the people, and are growing especially to the demand of polished rice, and it is very wide to be sold inside the country the foreign trade prospect.Therefore, the development Rice Production improves paddy rice gross yield and polished rice quality, for guaranteeing China people " grain ration " safety and social stability, has the important strategic meaning.
The Northeast's (comprising Heilongjiang Province, Jilin Province, Liaoning Province) is the paddy rice producing region of China's maximum, is the paddy rice advantage growing area of China's maximum, and is huge to domestic paddy rice market clout.The long-term rice growing area in the Northeast is more than 3,000,000 hectares, and output and area all account for the national paddy rice gross area and more than 40% of gross yield.Wherein, cultivated area was 3,140,000 hectares in 2005, accounted for 43.0% of national rice area; 2118.9 ten thousand tons of gross yields account for 40.1% of national paddy rice gross yield; Cultivated area surpassed 3,350,000 hm2 in 2006; Cultivated area was increased to 385.33 ten thousand hectares in 2008, increased by 1,200,000 mu than 2007, and amplification is 2.1%; 2,830 ten thousand tons of gross yields increased by 1,770,000 tons than 2007, and amplification is 6.7%.
Yet the Northeast is between 38 ° to 53 ° of north latitude, and latitude height and leap amplitude are big, and mean temperature of air is 0.5～6 ℃ throughout the year, and temperature is low and accumulated temperature is also low.Though can satisfy the needs of ripe plant growth in a year, chilling injury is to cause the not main affecting factors of high shakiness of rice yield.But run into the serious chilling injury year underproduction more than 10,000,000,000 jin.More serious since the establishment of the nation chilling injury year has 5 times, and promptly 1954,1957,1969,1972,1976 years.In chilling injury year, the about 13-35% of the average underproduction of crops.The frequency that seriously damages to plants caused by sudden drop in temperature is with large and small Xing'an Mountains.The ground, Changbai Mountain and the Three River Plain are the highest, and average 4～5 years once.All the other areas, frequency is between 10～20%.Damaging to plants caused by sudden drop in temperature of northeast can divide delaying type and two types of obstruction type, and two types had concurrently and can claim mixed type the time that has.Cool-summer damage due to delayed growth, mainly be breeding time temperature lower, make postpone at crop heading stage and grouting slowly so that can not be ripe before the frost in autumn, grain heavily reduces, sterile grain rate is big, maturity is low; Cool-summer damage due to impotency is to run into the continuous several days low temperature of short-term harm floral organ in crop booting, flowering stage, cause empty grain to heighten to cause the underproduction (open and vow, Xu Yirong. cold ground rice makes [M]. Harbin: Heilungkiang science tech publishing house, 1990.400-446.).For example, chilling injury takes place in eastern Jilin in 2002 and Heilungkiang Dao Qu, and the underproduction that causes is up to more than 30%.Heilungkiang Dao Qu obstacle in 2005 damages to plants caused by sudden drop in temperature the large tracts of land ghost that causes descends output significantly.
Therefore, damage to plants caused by sudden drop in temperature on the biochemistry mechanism based that postpones the paddy rice normal mature the Northeast in research, further studies chemical regulation technique, is extremely important to guaranteeing the Northeast's rice high yield stable yields.
There are some researches show, coerce down damaging to plants caused by sudden drop in temperature, take rational Crop Physiology measure can alleviate the influence of damaging to plants caused by sudden drop in temperature within the specific limits paddy rice.The wherein passive measure of being Protected from Cold comprises that seedling is strengthened in cultivation, the light seeding thin planting is resisted to damage to plants caused by sudden drop in temperature, apply fertilizers scientifically, Guan Shui resists chilling injury, as measures such as Shaoshi nitrogenous fertilizer, increasing the p application rate, shallow irrigation water lift temperature, but, though can resisting to a certain extent, these measures damage to plants caused by sudden drop in temperature, can not guarantee the paddy rice normal mature, cause the underproduction equally.Initiatively resist cold measure to comprise blade face spray phosphate fertilizer, spray heating agent and plant growth retardent such as S 3307, paclobutrazol etc., though these measures have increased the cold resistance of paddy rice to a certain extent, but, the foliage-spray delayer is handled the underproduction effect that causes to paddy rice even greater than the influence of damaging to plants caused by sudden drop in temperature, so, practical application effect is not good, can't large-area applications in production.Therefore, cold resistance and high yield with dual raising paddy rice are target, from coordinating anti-cold physiology and the high yield physiology angle of paddy rice, synthetic, assembly new plant growth regulator, explore suitable chemical regulation measure, excavation paddy rice self is resisted and damages to plants caused by sudden drop in temperature the potentiality of coercing, and coordinates the relation between cold resistance and the high yield, promote the paddy rice normal mature, improve the yield and quality of rice.To be extremely important to stable China's the Northeast's rice yield that improves.
Summary of the invention
The purpose of this invention is to provide a kind of dual raising paddy rice cold resistance and highly yielding ability plant growth regulator.
The invention provides the anti-low temperature of a kind of paddy rice expansion fringe resistant to lodging and increase a yield-increasing modifying agent, this conditioning agent contains following component: polyaspartic acid salts 50～150g/L, metasilicate 10～30g/L, plant growth regulator 20～30g/L, activating agent and spreader-sticker 65～67g/L.Preferably, polyaspartic acid salts 100g/L, metasilicate 20g/L, plant growth regulator 20～30g/L, activating agent and spreader-sticker 65～67g/L, solvent is preferably water.
