Description
Technical field
The present invention relates to plant growth regulator, particularly relate to a kind of Rice Resistance adverse circumstance specular removal lodging resistant production gain conditioning agent, its preparation method and application.
Background technology
Paddy rice is one of China's staple food crop, is the main grain ration of the whole nation more than 65% population, is mainly distributed in Plain, the middle and lower reach of Yangtze River and Northeast plain, long-term cultivated area 4.5 hundred million mu, gross yield 2.04 hundred million tons, accounts for 32.25% of world's rice yield, ranks first in the world.For a long time, the main rice workspace of China, run into the various disaster of adverse circumstance in various degree to coerce throughout the year, as violent storm, a run of wet weather, flooded stain, low temperature, the low light level etc., underproduction amplitude more than 10% ~ 40%, long-term disaster area reaches more than 40% of Monitoring of Paddy Rice Plant Area, badly influences the high-quality of paddy rice, high yield and stable yields, causes huge economic loss to peasant.
Research shows, in rice growth process, cold in the late spring causes the rotten kind of In Middle And Lower Reaches of Changjiang River paddy rice, rotten bud, growth retardation; Summer Low Temperature is rainy causes mercury dropped, illumination deficiency and soil accumulated water, affects paddy rice normal growth and grows, grow slow, the retardation phase, cause sterile and partial sterility, form a large amount of empty, blighted grain; The chilling injury in autumn causes growth period duration of rice to be postponed, and flowering, pollination and fertilization process are influenced, and ripening rate reduces; Especially the violent storm in summer, directly causes the lodging of large of paddy rice, not only reduces output but also reduces rice quality, and bringing difficulty to harvesting.Therefore, the low temperature in rice growth period, the adverse circumstance such as flooded stain and the low light level have had a strong impact on the yield and quality of paddy rice.Therefore, strengthen paddy rice and resist the ability of environment stress to ensureing that rice high yield stable yields is extremely important.
There are some researches show, under the environment stress such as chilling injury, rainy flooded stain, take rational Crop Physiology measure can alleviate temperature and water stress within the specific limits to the impact of paddy rice.Wherein, cultivation technique measure comprises: select lodging resistance kind, cultivate strong seedling, improve Planting Patterns, rationally rich water plan strategies for, the harm that chilling injury and rainy flooded stain are brought can be reduced to a certain extent; But, the lodging in storm is then produced effects not quite.At present, be the plant growth regulator of principal component mainly with foliage-spray paclobutrazol, uniconazole P in production, lodging resistance in rice performance is improved by regulation and control stem stalk height and toughness, although these measures add the lodging tolerance of paddy rice to a certain extent, but, due to paclobutrazol (PP333, neoprene azoles) long half time, Long-Time Service causes field residual quantity excessive, not only had a strong impact on emerging of succession crop, and in rice, the residual quantity of paclobutrazol exceeds standard, do not meet the standard of food processing, cause Rice producing quality to reduce.Secondly, foliage-spray paclobutrazol can control fringe and grow, and causes grain number per spike to reduce, causes Severe Reduction.Therefore, for solving the problems referred to above existed in Rice Production, for the growth characteristic of paddy rice, the novel growth regulator sought to regulate and control to nourish and grow, promote reproductive growth, promote paddy rice high-quality, high yield, stable yields, is extremely important to guarantee paddy rice high-quality, high yield, stable yields.
Summary of the invention
The object of this invention is to provide a kind of Rice Resistance adverse circumstance specular removal lodging resistant production gain conditioning agent, its preparation method and application.
The invention provides a kind of Rice Resistance adverse circumstance specular removal lodging resistant production gain conditioning agent, this conditioning agent containing, for example under component: 5-ALA 5 ~ 20g/L, TrinexAN_SNacethyl 230 ~ 330g/L.
Wherein, described 5-ALA is preferably 10 ~ 20g/L, is more preferably 20g/L.
