Abstract
The invention relates to a high-yield corn dense planting cultivating method, which comprises the following steps of seed treatment, field planting, field management, weeding and management of water and fertilizer. The good hybrid corn variety with the characteristics of dense planting resistance, dwarf, compact plant type, matured live stem, proper mature period, no balding of fruit cluster, lodging resistance, and pest and disease resistance; furrows are formed for planting, the width of each furrow is 120-140cm, and the height of each furrow is about 20cm; the wide and narrow line planting type is adopted, the distance of wide lines is 100-150cm, and the distance of narrow lines is 40-50cm; the distance of pits is 35-40cm, and three plants are planted in each pit; every two treated seeds per point are sowed into each furrow, the soil is covered while the seeds are sowed, the soil with thickness of one inch is covered and treaded, and 5700-6700 plants are reserved per mou.
Description
Technical field
The present invention relates to a kind of high-yield cultivating method of corn, is a kind of high-yield corn planting culture method specifically.
Background technology
China is a populous nation, and corn is one of Three major grain crops.Maize Production, in the agricultural production of China, occupies very consequence in national economy.Development Maize Production, to increasing farmers' income, ensures that national food security and even economic security are of great immediate significance.Although the development of China's corn year production is very fast, corn year production not enough, also have larger gap with the market demand of China corn, all need a large amount of import every year.By the impact of China's poor and Cropping structure adjustment of agricultural land resourses per capita, China's corn seeding area is difficult to be expanded.The agricultural production of current China lacks again the effective corn yield increasing of system and increase income cropping pattern.Therefore improve corn yield per unit area and just become very urgent research topic.
Summary of the invention
The object of the invention is to solve deficiency of the prior art, a kind of high-yield corn planting culture method is provided.
The present invention is for achieving the above object, and the technological means adopted is:
Select resistance to dense planting, of short stem, plant type is compact, straw staygreen, maturing stage are suitable for, fruit ear is without superior hybrid crosses corn variety that is bald, resistant to lodging, disease and insect resistance.
Play furrow plantation, furrow are wide 120-140 centimetres, furrow height about 20 cm, wide-narrow row planting, wide every trade is apart from 100 ~ 150 centimetres, narrow row line-spacing is 40 ~ 50 centimetres, and cave distance is 35 ~ 40 centimetres, every cave 3 strain, processed good seed often being put two grain is sowed in ditch, broadcast while blinding, blinding 1 cun is also steady and sure, and mu stays seedling 5700 ~ 6700 strain.
Existing fertilising basis increases humic acid complex fertilizer base fertilizer, existing base fertilizer compound potassium sulfate fertilizer 40 kgs/acre, be affixed by phosphoric acid diamines 10 kgs/acre and make base fertilizer, apply bio-bacterial manure 1 kg/acre simultaneously, notice that seed manure is separated, fertilizer and seed distance 8 ~ 10 centimetres, humic acid complex fertilizer subsoiling holostrome applied once fertilizing amount is that 1187.5kg/hm2 is interval at 10-25cm, topdress: when 5-6 leaves, first time imposes seed manure, execute 7.5-10 kilograms, urea for every mu, trench digging row replacement in the middle of furrow, then blinding, when 8-9 leaves, carry out second time to topdress, namely execute and attack stalk fertilizer, current fertilizer amount accounts for about 25% of total fertilizing amount, every mu of sealing fertilizer 10 kilograms adds 7.5 kilograms, potassium chloride, fertilization mode is row replacement, when 14-15 leaves, carry out third time fertilising, namely execute and attack ear manuer, current fertilizer amount accounts for about 35% of total fertilizing amount, every mu of sealing fertilizer 20 kilograms adds 10 kilograms, potassium chloride, use in conjunction with large ridging, a top dressing is carried out respectively when 9 leaves and 15 leaves, mu sprays with 50 grams of rare earths or 800-1000 times of potassium dihydrogen phosphates.
After planting spray herbicide Acetochlor, atrazine, prevent and kill off Weeds at seedling; Intertillage: before envelope ridge, be combined, cultivation and banking height 7 ~ 8cm with weeding, promotes that aerial root is grown, prevents lodging, is beneficial to irrigation and drainage, buries weeds; Spray plant growth regulator, because seedling number increases, in corn 8 ~ 10 leaf phase, sprays the short control dense planting conditioning agent prepared, the fresh fat ethrel of amine, mu consumption 40 grams/acre.
Corn enters vigorous growth from jointing to heading plant, needs washiness, and especially taking out male front and back is critical periods that corn needs water; at this moment lack of water, depauperation, the male and female florescence is inharmonious; impact pollination; cause bald, lack grain or empty stalk, so this period should keep water capacity 70-80%, the area that rainwater is many; note digging trenches to drain the water away; horn mouth to heading stage is the harm phase that corn borer is caused harm, all to spray 500-800 times of chlorophos or dimehypo+Bt powder mixing spray, control of maize snout moth's larva.
Invention advantage
Humic acid Cotton seeds has corn seedling and increases effect, promotes the growth of corn seedling overground part and root system development, makes that stem is thick, seedling dry weight, root are long, root dry weight increases, and root/shoot ratio pole significantly improves.Humic acid Cotton seeds also obviously can reduce proline and the mda content of corn seedling simultaneously, improves chlorophyll and soluble sugar content and SOD active, improves biomembranous permeability simultaneously.The modal change of corn seedling caused by humic acid Cotton seeds and a series of physiological actions of generation, can strengthen the drought resistance of corn seedling, reach keeping crop seedling from drought, for the healthy growth in corn later stage lays the foundation.
The wide every trade of this method is apart from 100 centimetres ~ 150 centimetres, and wider than the line-spacing of common species planting technology 50 ~ 100 centimetres, can make full use of Dominance in border row, more abundant ventilation and penetrating light, and easy access, be convenient to field management.
Narrow row line-spacing is 40 ~ 50 centimetres, is both applicable to film-covering planting, again can drip irrigation, has both been applicable to single household's plantation, has been more suitable for spread.
Every cave three strain reduces pearl distance, increases cave distance, enhances ventilation effect.Three strains simultaneously grow together, and root system is together intertwining, improves lodging tolerance.Because cave is apart from being 35 ~ 40 centimetres, stays seedling 5700 ~ 6700 strain according to breediness mu, corn yield per unit area can be increased substantially.
The inventive method is simple to operate, as long as change or make into three seed trays into, can sow with regular drill.
About the inventive method every mu stays seedling 2000 strain than common species planting technology more, corn yield per unit area is significantly increased, through multiple spot 155 mu of large area experiments, average mu increases production 244 kilograms.Not only significantly can increase farmers' income, and guarantee national food security is significant.
