Corn is the staple food crop of China, with the raising of China's level of agricultural production, the requirement to cereal crops
And be gradually transformed into from simple volume increase and increase income and upgrading synergy.In recent years, grain agricultural product price growth rate and economy
Too slow, the increase persistently dropped with countryside tax system cost of particularly nearly 2 years corn prices is compared in crop, industry and service trade,
Peasant income is relatively small, and the labour for the line that causes to be engaged in agricultural production gradually decreases, and plants grain enthusiasm and is severely impacted.
According to China's national situation, although production structure needs the chief crops such as adjustment, but corn wheat also to plant, and to ensure grain
Safety, this just proposes higher requirement to agricultural production, such as：Suitably cultivate and receive selecting, gently simplifying production technology for machinery
Using, the cultivation of breeding with promoting etc., this is also the road for the certainty that Comprehensive Productivity is improved.In current corn production process
In, the proposition of " seven points of kinds three are in charge of " measure has substantially focused on requirement of the corn in terms of sowing, and this link has been grasped just
Substantially yield is ensure that, " seven points of kinds " mainly includes sowing specification, soil cultivation requirement, fertilizer nutrient input etc., but at present
The problem of link also deposits such or such particularly is being sowed in corn mechanization plantation, such as：Production custom is that combine is received
Obtain wheat, stalk and shed mulching soil surface, no-tillage seeding, mechanical simple grain single file seeding corn or to ensure many sowings of full stand
Thinning final singling, seed manure planter tool trench digging impose fertilizer or in a series of machinery ginsengs such as corn seeding one-time use composite fertilizer again

There are many irrational modes of operation, such as：(1) stalk and high wheat stubble that wheat combine tool is arbitrarily shed are possible to
The seeding quality and Phase ofsprouting of corn are influenceed under no-tillage；(2) mechanical monoseeding is likely due to seed matter
Amount problem or subterranean pest-insect, which gnaw to bite, causes the disconnected ridge that is short of seedling, and influences density, and many sowings are except wasting seed increase seed costs
Outside also produce the later stage thinning and final singling operation, labour input increase；(3) the most important constituent element of corn yield is influenceed
It is exactly density, but blindly raising density can increase colony's closing early ageing, and single productive forces decline the raising for being also unfavorable for yield；
(4) influenceed by the field degree of packing, flatness after wheat harvest, mechanical no-tillage seeding corn depth differs, influence Phase ofsprouting, and on
The long-term soil rotary tillage operation of stubble wheat causes topsoil to shoal, and is unfavorable for the profound soil of bundle absorption under corn seed root system and supports
Point, it is also possible to occur later stage lodging phenomenon；(5) influenceed by agricultural workforce's shortage, the later stage is or not Common compound fertilizer " one bombards "

Consume excessively, at the same the corn of sowing can due to subsoiling dressing furrow on one wire, cause maize seed to fall into dressing furrow to cause
Emergence difficult phenomenon, while using etc. line-spacing or the sowing of size row also due to the density reduction that causes of the disconnected ridge that is short of seedling is so as to shadow
Ring corn yield；Chinese patent literature CN 104521383A (application numbers：201410776743.8) disclose a kind of corn seed fertilizer
With the fertilizing method for broadcasting formula fertilizer distributor, this method is applied by the adjustment for setting multiple fertilizing boxs to carry out nutrient formula
Fertilizer, under conditions of existing formula compound fertilizer popular scale, this set obviously increases power set, and causing need not
The trouble wanted, the bad precipitation that may result in of which link operation is uneven, furthermore peasant household need to purchase by all kinds of means simple substance fertilizer, from
Row formula can cause program cumbersome, also because technical force is not enough this method utilization rate can be caused not high.
