Abstract
The invention discloses a high-yield high-efficiency cultivation method for spring corns in hilly and mountain areas. The method includes the steps of selecting drought-resistant barren corn varieties, applying enough base fertilizers, applying organic and inorganic fertilizers, applying fertilizers and slow release fertilizers, turning up soil deeply, performing multi-layer fertilizing, covering color-matching mulching films, controlling pests and harvesting in due time. According to the method, the spring corns are planted in hilly and mountain areas, the early spring freeze injury is reduced through covering of mulching films, the topdressing link is reduced through additionally applying organic fertilizers and slow release fertilizers, labor is saved, the yield per mu can reach above 650kg, and economic and social benefits are improved obviously.
Description
Technical field
The present invention relates to a kind of hilly and mountainous land High-yields of Spring Maize efficient cultivation method, belong to Technique for Corn Cultivation field.
Background technology
Corn is important with China in the world cereal crops and forage crop, within 2012, national corn yield is 20,812 ten thousand tons, increases production 1,534 ten thousand tons, and corn yield exceedes 3,830,000 tons of rice yields, become the first cereal crops of China, development Maize Production has great importance.
The one, guarantee national food security needs.National food safety, mainly comprises grain ration safety and feed and the safety of processing grain.Grain ration safety is mainly to guarantee paddy rice, Wheat Production stable development.The safety of feed processing grain, mainly guarantees the stable development of corn, potato.Increased by livestock breeding and industrial requirement and pull, current China corn consumption rapid growth, supply-demand relationship changes.China's corn produces at present needs general layout in a basic balance to change to the tight slightly direction of supply and demand.Therefore, must dispose early, promote effectively, accelerate the development of China's Maize Production.
The 2nd, the needs of increasing farmers' income.Along with China's livestock breeding sustained, stable growth, feed demand amount constantly increases, and it is rigidity that the year of fodder maize consumption increases.Meanwhile, the development of the processing industries such as food, medical science, has also effectively pulled the development of the processing industry take corn as raw material.Now, the development of the Maize Production of China main producing region, has not only ensured market supply, and has become the important sources that increasing peasant income and local finance increase income.So development Maize Production, meets corn as raw material, promotes livestock breeding, meets the development of livestock breeding and processing industry, this is not only into guarantee market supply, is also the needs that meet increasing peasant income and increase financial income aspect, main producing region.
The 3rd, the needs of reply challenge from international market.Enter 21 century, global corn consumption is steady growth trend, after 2004, due to the rapid growth of some world Maize Production big country alcohol fuel industry, has driven corn industry consumption significantly to increase.Directly affect on the one hand the volume of trade of world market corn.Pulled on the other hand the rise of international market corn price.China is that corn is consumed big country in the world, in the situation that the quantum of international trade faces minimizing, must base on our country, and accelerates development, and guarantees substantially self-supporting.
Therefore, accelerate Maize Production development, be both related to and met the current market demand, be related to again grain-production stable development from now on, be more related to increase farmers' income and tackle international market and change.Must depend on science and technology, fully exploit potentialities, stabilize cultivation area, improves per unit area yield, ensures corn effective supply; Must protect peasant's enthusiasm for production, reinforcement work guiding, makes Maize Production meet industry development needs.
But for a long time,, spring corn sowing early, is easily subject to low temperature effect; While is due to the production feature of corn, corn developmental stage need to topdress, waste manpower energetically, along with rural labour shifts in a large number to city, particularly for the spring corn of hilly and mountainous land location, produce, must improve the cultivation step of corn, it is time saving and energy saving to accomplish, the so just cultivating method of crop of necessary a kind of high-yield and high-efficiency, but in prior art, have no report.
Summary of the invention
The object of the invention is to solve deficiency of the prior art, a kind of hilly and mountainous land High-yields of Spring Maize efficient cultivation method of simple, time saving and energy saving, remarkable in economical benefits is provided.
The present invention is for achieving the above object, and the technological means adopting is:
A kind of hilly and mountainous land High-yields of Spring Maize efficient cultivation method, its step comprises: select drought resisting barren-resistant corn variety, use sufficient base manure, ground, multilayer fertilising are executed, ploughed deeply to organic-inorganic fertilizer application, slow-release fertilizer fertilely mixedly, cover color matching mulch film, prevention and elimination of disease and pests, results in good time, the barren-resistant corn variety of described selection drought resisting refers to the corn variety of selecting to be adapted at Hills plantation; Describedly use sufficient fertile mixed the executing of base manure, organic-inorganic fertilizer application, slow-release fertilizer and refer to every mu and use pig manure 5000-6000kg or chicken manure 2500-3000kg, urea 15-16kg, potassium chloride 8-10kg, superphosphate 25-27kg, slow-release fertilizer of carbamide 15-17kg; Described ploughing deeply refers to employing subsoiling whole layer placement of fertilizer precision seeder, and subsoiling 25-30 centimetre, breaks tillage pan, increases soil water storage ability, reduces liquid manure and runs off; The fertilising of described multilayer refer to by precision seeder by full vegetative period 6 layers of fertilizer parts execute around maize root system, be beneficial to and absorb the time of infertility, reduce leaching loss; Described covering color matching mulch film refers to Ridged plant, adopts the wide-narrow row planting method of ridge two row, in sowing, covers chequered with black and white color matching mulch film on ridge, plays the effect of insulation soil moisture conservation, does not use weed killer herbicide simultaneously; Described in good time results refer to when the flavescence of plant bottom, and bract is yellow-white and loose withered, and milk-line disappears and black layer formation, and seed is strong when glossy, should gather in the crops in time.
Further, the corn variety of described applicable hilly and mountainous land plantation is selected Zheng Dan 958, day No. 10, Thailand, red jade 86, Nongda108.
Further, described prevention and elimination of disease and pests refers in good time control of maize size leaf spot, corn rust, corn borer, maize aphids.
Beneficial effect of the present invention is: utilize the present invention to plant spring corn in Hills, by covering with plastic film, reduced Early spring freezing injury, by applying organic manure and slow-release fertilizer, reduced the link of topdressing, save labor, more than corn per mu yield can reach 650kg, economic benefit and social benefit are remarkable.
