Abstract
The invention discloses a yield-increasing composite regulator for preventing corn lodging. In terms of each kilogram of the composite regulator, 0.000031-0.00005 mg succinic acid, 20-60 mg uniconazole and 50,000-100,000 mg monopotassium phosphate are included. The invention also discloses a use method of the composite regulator. By using the invention, stumpish corn seedlings, developed root system, increased root quantity and enhanced activity of the root system are realized. By using the yield-increasing composite regulator disclosed by the invention, corns have the advantages of tough stalk, reduced and thickened space between the base and a third section of the plant, reduced plant height and low ear position descending, and an obvious effect of preventing the corn lodging is achieved; The color of the corn leaf is deepened, the intensity of photosynthesis is enhanced and the accumulation and operation of dry matters in the corn plant are accelerated; The corn yield is increased in such ways that the corn yield is increased by 5.2% in contrast to a condition with no corn plant lodging and the corn yield is increased by 15.4% in contrast to a condition with corn plant lodging.
Description
Technical field
The present invention relates to crops conditioning agent technical field, especially a kind of corn lodging compound conditioning agent of volume increase and using method of preventing.
Background technology
Corn is China's important food and forage crop, occupies extremely important status in national economy, and the rich and apology of corn yield becomes the key factor of left and right sides China grain supply and demand balance and decision animal husbandry development gradually.Corn lodging be since the stem stalk that extraneous factor causes from erectility to falling the phenomenon of folding.Lodging is the key factor that influences corn yield and quality always, and according to the interrelated data statistics, lodging causes corn underproduction 15-25%.China loses nearly 1,000,000 tons because of lodging causes maize yield every year.At present, along with improving constantly of China's maize culture level, dense planting becomes increasingly conspicuous with lodging contradiction, and because a lot of uncertain natural cause takes place, causes the corn lodging to cause that production loss presents the trend of aggravation.
Corn lodging has that stem falls, root falls and stem fractures etc. three types, and cause that the reason of lodging mainly contains: one, shooting stage liquid manure is excessive uses.Excessive as shooting stage liquid manure, it is prosperous partially growth to occur, and the plant internode is elongated, and supporting tissue is undeveloped, easily causes the stem lodging.Two, root system is undeveloped.The phosphate fertilizer deficiency, the former growth of root system is bad, or whole of poor quality, and root system buries shallow, and aerial root is undeveloped etc., root occurs in case wind is met in the back of watering or it's raining and blowing hard.Three, take out male preceding over growth.It is preceding prosperous excessively as if corn growth to take out hero, and the stem stalk is organized delicate, meets wind and the phenomenon that fractures promptly occurs.Four, density is excessive.The high density that covets volume increase, seeding row spacing is too small or thinning is insufficient, causes between strain crowdedly, internode is elongated, tissue looseness, cause stem or stem fracture.Five, sick worm harm.Between the shooting stage or take out male before sick worm harm stem stalk also easily cause lodging.
The approach that prevents the corn lodging at present has: one, rational close planting.According to soil fertility and breediness, rational close planting makes full use of luminous energy, can reduce few and the shallow and long lodging that causes of internode because of root system.Two, the rational application of fertilizer.According to corn plan yield and fertilizer provision from soil amount, implement nitrogen, phosphorus, potassium rational application of fertilizers, and, determine suitable period and fertilizing amount in conjunction with the corn regulation of fertilizer requirement, can effectively prevent lodging.Three, restrain the growth of seedlings fertilely.Than high fields, liquid manure restraining the growth of seedlings method is controlled in the preceding employing of jointing to liquid manure, and bundle and stem stalk stalwartness are anti-down under the short root.Four, select anti-kind of short stem for use.Five, seedling raising and transplanting.Transplant corn because seedling-slowing stage is arranged, stem stalk pier is real sturdy, and capacity for the resistance to lodging is strong.Six, chemical regulation.Maize root system builds up with function and brings into play the adjusting that is subjected to semiochemicalses such as endogenous hormones, and these semiochemicalses play an important role in the root cap contact.Use suitable plant growth regulating substance and can regulate and control growing of maize root system, improve root function, regulate the relation of root system and overground part, prevent lodging, improve the yield and quality.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of corn lodging compound conditioning agent of volume increase and using method of preventing at the deficiencies in the prior art.
The present invention adopts following technical scheme:
A kind of compound conditioning agent of corn lodging volume increase that prevents according to every kilogram of compound conditioning agent meter, comprises succinic acid: 0.000031-0.00005mg/kg; Forchlorfenuron 0.000031-0.00005mg/kg; Uniconazole P: 20-60mg/kg; Potassium dihydrogen phosphate: 50000-100000mg/kg.
The described using method that prevents the compound conditioning agent of corn lodging volume increase comprises and uses described compound conditioning agent seed dressing and/or in earlier stage described compound conditioning agent evenly is sprayed onto the blade position at the corn jointing.
The described using method that prevents the compound conditioning agent of corn lodging volume increase, wherein said sprinkling specific practice is: in corn jointing early stage, use conventional sprayer evenly to spray 30 kilograms of described compound conditioning agents to milpa, the degree of being with moistening.
Corn seedling is short strong, and well developed root system, quantity increase, and the root amount increases, and the root system vigor strengthens.Corn stem is tough and tensile, and plant base portion the 3rd internode shortens, increases thick, and plant height reduces, and the fringe position reduces down, prevents that corn lodging effect is remarkable.The maize leaves look is deepened, and intensity of photosynthesis strengthens, and quickens the accumulation and the running of milpa dry matter.Improve corn yield, under contrast milpa non-lodging situation, corn yield increasing 5.2%, under contrast milpa lodging situation, corn yield increasing 15.4%.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
