Description
Technical field
The present invention relates to a kind of cultivation method, particularly relate to a kind of corn with high yield, cultivation method resistant to lodging.
Background technology
Corn is the important grain of China and forage crop, occupies extremely important status in national economy, and the rich and apology of corn yield becomes gradually left and right China grain supply and demand balance and determines the key factor of animal husbandry development.Corn lodging be due to extraneous factor cause stem stalk from erectility to fall folding phenomenon.Lodging is the key factor that affects corn yield and quality always, and according to relevant statistics, lodging causes corn underproduction 15-25%.China causes nearly 1,000,000 tons of the production loss of corn every year because of lodging.At present, along with improving constantly of China's maize culture level, dense planting and lodging contradiction, and because a lot of uncertain natural causes occur, cause corn lodging to cause that production loss presents the trend of aggravation.
Corn lodging has the three types such as stem falls, root falls and stem fractures, and causes that the reason of lodging mainly contains: one, shooting stage liquid manure is excessive uses.As excessive in shooting stage liquid manure, occur that growth is partially prosperous, plant internode is elongated, and supporting tissue is undeveloped, easily causes stem lodging.Two, root system is undeveloped.Phosphate fertilizer deficiency, the former undergrowth of root system, or whole geological measuring is poor, root system buries shallow, and aerial root is undeveloped etc., once meet wind after watering or it's raining and blowing hard occurs that root falls.Three, take out male front over growth.If it is excessively prosperous to take out male front corn growth, stem tissue is delicate, meets wind and occurs the phenomenon that fractures.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, and internode is elongated, and tissue looseness, causes stem or stem fractures.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 at present corn lodging has: one, rational close planting.According to soil fertility and breediness, rational close planting, makes full use of luminous energy, can reduce because root system is few and shallow and the long lodging causing of internode.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 in conjunction with corn regulation of fertilizer requirement, determine suitable period and fertilizing amount, can effectively prevent lodging.Three, restrain the growth of seedlings fertilely.Liquid manure, compared with high fields, is adopted to control liquid manure restraining the growth of seedlings method before jointing, under short root, bundle and stem stalk stalwartness are anti-down.Four, select anti-fall kind of short stem.Five, seedling raising and transplanting.Transplanting Maize is owing to there being seedling-slowing stage, and stem stalk pier is real sturdy, and capacity for the resistance to lodging is strong.Six, chemical regulation.Maize root system builds up the adjusting that is subject to the semiochemicalses such as endogenous hormones with Function, and these semiochemicalses play an important role in root cap contact.Apply 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
For the problem of above-mentioned existence, the technical problem that the present invention mainly solves is to provide a kind of corn with high yield, cultivation method resistant to lodging
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
Whole ground, do furrow: on whole basis of leveling land, machinery does furrow, furrow face width 110cm, furrow obstruct wide 30cm, respectively sowing a seeding belt from furrow stalk 2.5cm both sides, a seeding belt is made up of two row seeds, and two row seeds are apart from 15cm, two row seeds are interspersed, and the vertical range of two adjacent cave seeds is exactly the spacing in the rows of plan
Corn is grown seedlings: select the good sandy loam of loosing soil fertility to add decomposed manure and mix at 5: 2 in proportion, with Baijunling sterilization, places and after 10 days, pack 128 caves into or 72 caves, cave are coiled for subsequent use; By Pan Jiao vola, ready cave water, live by 1/cave dry seeds, the thick fine earth of lid 1～1.5cm, then cover thin film or sunshade net; After seedling all sprouts, control temperature at 17～24 DEG C, humidity is 62～68%; In the time that seedling grows to 2 leaf 1 heart, cave dish to be mentioned, corn seedling main root has grown approximately 2～10cm of cave tray bottom leaking hole, all cuts off all main roots along cave tray bottom; Treat that seedling grows to 3 leaf 1 hearts, the new root system in bottom stretches out cave tray bottom leaking hole approximately when 0.5～2cm again, the transplanting of going to the field; Transplant first 3 days, whole day is placed in canopy by cave dish and practices seedling outward, strengthens the resistance of seedling; Fine day is transplanted after 4 o'clock in the afternoon, waters normal root water after cultivation;
When the soil plough horizon temperature stabilizations of 5～10 centimetres by 8 DEG C～10 DEG C, when field capacity 20% left and right, want sowing in time, conscientiously selected to seed before broadcasting, remove scab grain, worm food grain, broken kernel and impurity, the separately sowing of large granule, sowing last weekly selection fine day basks seeds 2～3 days, guarantee the normal germination and emergence of seed, the seed bud rate that simple grain is broadcast must reach more than 95%, cleanliness, purity reach more than 98%, water content is higher than 16%, otherwise is not suitable for carrying out monoseeding, selects suitable seed coat agent to carry out seed pelleting processing before corn seeding;
Field management: using of chemical fertilizer will be according to surveying soil formula, carry out balance fertilizing, two want deep fertilizer spraying, 14～16 centimetres of base fertilizer deep placements, topdress dark 7～10 centimetres, increase Potassium Fertilizer, potash fertilizer can improve the intensity of corn stem, increase the toughness of stem stalk, use potassium chloride or potassium sulfate 12.5～15,000 gram/acre, the anti-Chinese caterpillar fungus plague of rats of curing the disease, the one, weeding, broadcast rear preemergence application weed killer herbicide sealing weeding, select low-residual as far as possible, short residual effect weed killer herbicide, good at soil moisture content, calm weather sprays, can not respray or drain spray, if weeds in field is too much after final singling, in the time of 3～5 leaves of weeds, spray foliar herbicide after maize seedling, in the time that seedling grows to 3～4 leaves, remove seedling, weak seedling, sick seedling, Huang Miao, stay strong sprout, change control milpa height, 3.5 meters of above corn varieties of plantation plant height, the particularly tall and big dense planting kind of first beautiful 335 plant, applied chemistry medicament control strain to plant height,
Spray conditioning agent: in corn jointing early stage, use conventional sprayer evenly to spray 30 kilograms of described composite regulators to milpa blade, for spending, described conditioning agent, according to every kilogram of composite regulator meter, comprises succinic acid: 301-400mg/kg taking moistening; Forchlorfenuron 0.000031-0.00005mg/kg; Uniconazole P: 20-60mg/kg; Potassium dihydrogen phosphate: 50000-100000mg/kg.
