A kind of High-Yield Cultivation of Wheat method
Technical field
The present invention relates to a kind of wheat cultivating method, particularly a kind of High-Yield Cultivation of Wheat method.
Background technology
The wheat cultivation of prior art generally comprises following methods:
1, select breeding
Select best in quality, individual plant productivity is high, strong stress resistance, economic coefficient are high, the breeding of not early ageing, is conducive to realize very heavy above yield target.
2, meticulous whole ground, balance fertilizing
2.1 meticulous whole ground
For improving soil structure, strengthen soil water storage soil moisture conservation, carry out intensive cultivation carefully whole before broadcasting, 23~25cm turns over, carry out also field of tangerine stalk, not only strengthen soil fertility, and can break tillage pan, reach dark, thin, thoroughly, the standard of flat, reality, foot (water), be that dark (nonirrigated farmland 20~25cm is wanted in plow layer, rice stubble ground 15~20cm), after ploughing rake thin (broken), rake thoroughly, leveling, having peace of mind, reach Panasonic real, retain and conserve soil moisture.
2.2 do furrow trench digging
Ridge is built at base, sets up the facility that wheatland is filled with, draining matches, and digs " three ditches " (dead furrow, Yao Gou, head drain), and after the beginning of spring, dredging " three ditches " in time, communicates irrigation canals and ditches, to meet the requirement of filling, draining.
2.3 balance fertilizing
According to Variation of Integrated Soil Fertility situation, formulate fertilising scheme, take fertilizer as main, fertilizer, inorganic fertilizer, in conjunction with using, improve the content of organic matter in soil, thereby reach the object of balance fertilizing.When ploughing, to use sufficient base manure, organic fertilizer 30~45t/ hectare, pure N225.0kg/ hectare, P
2o
590.0~112.5kg/ hectare, K2075.0~112.5kg/ hectare, the loss of chemical fertilizer loss causing for reducing winter snows spring rain, avoid the wheat middle and later periods to take off fertile early ageing, to after the chemical nitrogen fertilizer of 50% left and right, move on to jointing to dividing and impose for 2 times between booting stage, thereby lysine in wheat seed, protein content are improved.
3, optimum period, is sowed in right amount
3.1 seed treatment
Before sowing, to carry out dressing seed or directly select capsuled seed.
3.2 proper seeding
For cultivating strong sprout, form well developed root system, the more Wheat Production colony of stem tiller number, make full use of heat resources, proper seeding, thereby lay the foundation for improving yield of wheat.General wheat is conducive to emerge most when field capacity is 70%~80%.Therefore, when date of seeding, soil moisture content clash, must accomplish suitable moisture in the soil sowing, can late sowing 3~5d, thus make wheat full stand.Generally day samming, before the winter, >=0 ℃ accumulated temperature is respectively 16~17, in the time of 650 ℃ sowing best, at during Wintering Period, can form for 61 heart strong sprouts of leaf.
3.3 seeding quantity
According to Wheat Varieties, sowing time, determine the seeding quantity of wheat, general semiwinterness, weak winter variety are respectively at October early and middle ten days, sowing by the end of September, seeding quantity 90~105kg/ hectare; Weak spring habit, spring varieties respectively in mid or late October, that late October to early November is sowed is more suitable, the amount of broadcasting 120~150kg/ hectare, along with date of seeding, postpones and suitably increases the amount of broadcasting.High yield field more than 7500kg/ hectare, Basic Seedling can be controlled in 1,800,000~2,250,000 strain/hectares, and at the beginning of 10 months by the end of September, sowing can drop to 1,500,000~1,800,000 strain/hectares.For tillering into the large-spike cultivar that fringe is low, suitable Basic Seedling 1,950,000~2,700,000 strain/hectare.[2]
4, science field management
4.1 apply fertilizers scientifically and weeding
For preventing the disconnected ridge phenomenon of being short of seedling, guarantee wheat safe overwintering, pour water in time, make wheat form strong root.For making control of weeds effect better, can carry out chemical weed control in mid-January to late Febuary.Mid-February, mid or late March imposed respectively chemical fertilizer 75~120,120~150kg/ hectare to by the end of February, promoted the wheat jointing of turning green, and improved the tillering capacity of wheat.At the beginning of 3 months, to water the water of turning green, middle fertility, colony is on the low side Yu fertility is high, colony is suitable or bigger than normal wheatland respectively the shooting stage slightly before or jointing initial stage, jointing later stage topdress and water.[2]
4.2 chemical regulation lodging-preventions
Wheat lodging is divided into 2 kinds of root lodging and stem lodging, and general main is that stem lodges, be mainly due to early stage amount of application of nitrogen fertilizer larger, cause wheat population excessive, field closing, ventilation and penetrating light is bad, the prosperous length of wheat excessive growth, basal internode is long, and the later stage occurs that strong wind weather wheat easily lodges.Therefore,, in Wheat Production, should apply fertilizers scientifically and water according to the fertility state of soil.
4.3 heading and grouting maturing stage
Wheat heading flowering period (in 4 months, the last ten-days period), is control wheat aphid, midge worm, mythimna separata, rust, powdery mildew and red viral disease etc., extends wheat growth stage, improves output, can spray insecticide, uses continuously 1~2 time., pour water 1~2 time meanwhile, pour water for the 1st time and carry out at first fringe blooming stage, to protect flower, increase the short grouting of grain, reach the object that grain is large, grain is heavy, prevent root system early ageing; Filling with wheat yellow water the 2nd time, to keep the skin wet, and is that the 2nd batch of crop of replay cooked early-stage preparations.
5, gather in the crops in good time
Generally June early and middle ten days wheat be mature on the whole, the harvesting during jaundice of the wheat head of whole wheatland 2/3, wheat wax ripeness latter stage is best harvest time.But wheat can not be too ripe, in order to avoid seed comes off and reduces harvest.Wheat will point kind carry out single receipts, single solarization, single storage, in order to avoid variet complexity, commodity and the economic worth of reduction wheat.
Adopt said method to carry out wheat cultivation, its weak point is, output is lower.
