Description
Technical field
The present invention relates to a kind of cultivating method of crop, more particularly to a kind of corn high yield cultivating method resistant to lodging.
Background technology
Corn is the important grain in China and forage crop, and extremely important status, corn production are occupied in national economy
An important factor for rich and apology of amount has been increasingly becoming left and right China grain supply and demand balance and has determined animal husbandry development.Corn lodging is
Since the stalk of extraneous factor initiation is from upright state to the phenomenon that folding.Lodging is always to influence the weight of corn yield and quality
Factor is wanted, according to relevant statistics, lodging leads to corn underproduction 15-25%.The yield of corn is damaged caused by lodging every year in China
Lose nearly 1,000,000 tons.Currently, with the continuous improvement of China's maize culture level, dense planting becomes increasingly conspicuous with lodging contradiction, and due to
Many uncertain natural causes occur, the trend for causing corn lodging to cause production loss that aggravation is presented.
Corn lodging has stem to fall, root falls and the three types such as stem fractures, and causes mainly to have the reason of lodging：One, the jointing stage
Liquid manure is excessively applied.If jointing stage liquid manure is excessive, occur growing partially prosperous, plant internode is elongated, and mechanical tissue is undeveloped, easily causes
Stem lodges.Two, root system is undeveloped.Phosphate fertilizer is insufficient, and root system original undergrowth or site preparation quality are poor, and root system buries shallow, and aerial root is not
Prosperity etc., after watering to the wind or it's raining and blowing hard root occurs and fall.Three, over growth before pumping is male.If taking out male preceding corn growth mistake
Prosperous, stem tissue is delicate, breakage phenomenon occurs to the wind.Four, density is excessive.The high density that covets is increased production, and seeding row spacing is too small
Or thinning is insufficient, causes crowded between strain, internode is elongated, tissue looseness, causes that stem falls or stem fractures.Five, disease pest endangers.Jointing
Disease pest endangers stalk and also easily causes to lodge before period or pumping are male.
Prevent the approach of corn lodging from having at present：One, rational close planting.Foundation soil fertility and breediness, rational close planting, fully
Using luminous energy, it can reduce and lodge caused by root system is few and shallow and internode is long.Two, the rational application of fertilizer.According to corn scheduled production
With fertilizer provision from soil amount, implements nitrogen, phosphorus, potassium rational application of fertilizers, and combine corn regulation of fertilizer requirement, determines suitable period and dose,
It can effectively prevent lodging.Three, restrain the growth of seedlings fertilely.To liquid manure compared with high fields, restrained the growth of seedlings method using control liquid manure before jointing, is pricked under promoting root growth and stem
Stalk stalwartness is anti-down.Four, anti-fall kind of short stem is selected.Five, culturing and transplanting seedlings.For Transplanting Maize due to there is seedling-slowing stage, stalk pier is sturdy in fact,
Capacity for the resistance to lodging is strong.Six, chemical regulation.Maize root system, which is built up, to be adjusted with Function by semiochemicals such as endogenous hormones, these
Semiochemicals play an important role in root cap contact.It can regulate and control maize root system using suitable plant growth regulating substance
Growth and development improves root function, adjusts the relationship of root system and overground part, prevents from lodging, improve the yield and quality.
