Description

A kind of efficient new method of rice set wheat volume increase

Technical field

The present invention relates to proportion of crop planting field, specifically it is a kind of make rice, wheat increase yield synergy new technology.

Background technology

At present according to traditional rice, wheat planting method, limited land resource, the per mu yield of rice, wheat are wasted Also it does not improve, is less useful for managing, virtually increase work cost.

Invention content

The present invention is to solve the management method of traditional rice and wheat, and invention one kind keeps the operatic circle big New technology.

For the present invention in order to solve the above technical problems, the technical solution taken, a kind of rice set wheat increases production efficient new technology, It is characterized in that including following procedure：

1, variety selection and seed treatment, rice set wheat preferably select the semi-winterness kind that moisture-proof, lodging resistance are strong, winter resistance is good, with It avoids since date of seeding is relatively early, tillering node leads to freeze injury in soil layer surface.In order to promote wheat seed after-ripening, hair is improved Bud rate should bask seeds 2~3 days before sowing.

2, it begins sowing in good time, rice covers the sowing of wheat 7~10 days generally before rice harves.Local suitable set date of seeding, is in September The last ten-days period to early October is determined by the rice actual cut phase.Sowing is too early, and the symbiosis phase is long, lacks illumination and easily leads to wheat seeding Form thin and weak seedling；It is too late, there is dew seed because of no covering, it is difficult to which full stand cannot achieve the effect that volume increase.

3, field management.Downgrade control, due to early period and rice symbiosis, wheat is easy to alter height.To promote low position tiller hair It is raw, enhance the antifreeze capacity for the resistance to lodging of plant, improve rate of tillering panicle, in four to the six leaf phase of wheat seeding, rich 750 g/hm2 is strengthened to water with short 450~600 kg are sprayed, and carry out dwarfing control.

4, balance fertilizing, rice stubble wheatland fertility is not generally high, to capture the high yield of Wheat After Getting Rice, it is necessary to further increase fertilizer Input, scientific utilization of fertilizer accomplish that organic fertilizer is combined with inorganic fertilizer, nitrogen, phosphorus, potassium, micro- fertilizer cooperation, base manure, top dressing, the outer spray fertilizer knot of root It closes.Fertilizer application should grasp the principle of " preceding ruthless, in skilful, rear weight ".

5, disease pest and weed is prevented.Rice covers wheat, and usually banded sclerotial blight and spider occur seriously by the end of February, are main controlling objects；4 The end of month, main controlling object was powdery mildew, followed by banded sclerotial blight and aphid [6].Wheat During Later Period of Growth need to carry out the mixed spray of medicine fertilizer, together When prevention small brown rice planthopper, head blight, fringe aphid and mythimna separata, powdery mildew, rust etc..It is typically chosen the withered spirit of standing grain, flolimat, poisons with poison The medicaments such as tick, jinggangmeisu, triazolone.

Technique effect

The solution have the advantages that using above-mentioned technical proposal, avoid rice maturity postpone, autumn sowing season shadow too late The problem of ringing wheat safe overwintering, and can guarantee that rice lives a maturation to always, increase After-ripening, alleviates sowing period labour It with the contradiction of Work machine anxiety, realizes wheat and makees the abridged edition produced, saving of labor, simplification, high yield and efficiently, reached that rice and kernel is double to be received Purpose.

Specific implementation mode

1, variety selection and seed treatment, rice set wheat preferably select the semi-winterness product that moisture-proof, lodging resistance are strong, winter resistance is good Kind, to avoid since date of seeding is relatively early, tillering node leads to freeze injury in soil layer surface.In order to promote wheat seed after-ripening, Germination percentage is improved, should be basked seeds before sowing 2~3 days.5% jinggangmeisu aqua, 500 g can be used, to 4 kg of water, it is 50 to mix wheat seeds amount Kg, bored 3~4 hours of heap, dries spare prevention banded sclerotial blight after it is fully absorbed.

2, it begins sowing in good time, rice covers the sowing of wheat 7~10 days generally before rice harves.Local suitable set date of seeding, is in September The last ten-days period to early October is determined by the rice actual cut phase.Guarantee sowing can repeatedly be broadcasted sowing uniformly, method is：First by wheat Seed broadcasts sowing 40%~50% along rice row, and seed is then taken to broadcast sowing 40%~45% perpendicular to rice row, remaining seed is in field side surrounding It broadcasts sowing.Meanwhile it is noted that beating rice strain causes to lack to ensure that seed uniformly lands to avoid due to broadcast leakage, replay after broadcasting sowing Seedling, disconnected ridge, clump seed, pimple seedling.

3, field management.Downgrade control, due to early period and rice symbiosis, wheat is easy to alter height.In four to the six leaf phase of wheat seeding, 450~600 kg of water is sprayed with short strong rich 750 g/hm2, carries out dwarfing control.Cover it is antifreeze, after receiving rice neat seedling stage want and Early covered.Before 3 leaf of wheat, 1 heart, can and mechanical means mating by three ditches, excavate field septal fossula, so that uniform wheat is covered mud 1.0 cm or so achieve the purpose that nurturing staff and improve the percentage of earbearing tiller.Conditional place can use farmyard manure or rice straw mulching.Ditch It is mating, the field of wheat interplanting should dig the zanjon of 1 15~20 cm every 3~4 m, ensure that wheat paddock draining is smooth.Water It after rice harvest, first has to hold the edge of a field ditch successfully, secondly opens 1 flute every 2 m, and make ditch soil uniform fold furrow face；Every 20~ 30 m open 1 Yao Gou again.Flowering stage reaches in combination with preventing disease pest control foliage-spray potassium dihydrogen phosphate and protects the anti-early ageing of leaf, increases Grain weight.

4, balance fertilizing, rice stubble wheatland fertility is not generally high, to capture the high yield of Wheat After Getting Rice, it is necessary to further increase fertilizer Input, scientific utilization of fertilizer accomplish that organic fertilizer is combined with inorganic fertilizer, nitrogen, phosphorus, potassium, micro- fertilizer cooperation, base manure, top dressing, the outer spray fertilizer knot of root It closes.Fertilizer application should grasp the principle of " preceding ruthless, in skilful, rear weight ".Specific measures of fertilizer：To ensure that wheat age at weaning fertilizer supplies It answers, 150~225 kg/hm2 of 105~150 kg/hm2 of urea and composite fertilizer should be applied 3~5 days before harvesting rice.Heavy dressing is strong Seed manure, fertilizer amount are 30~45 t/hm2 of organic fertilizer, 150~225 kg/hm2 of urea, 525~600 kg/hm2 of composite fertilizer. To promote balance, protecting steady length, 120~150 kg/hm2 of urea is imposed in wheat Wintering Period or period of seedling establishment.Jointing fertilizer and booting fertilizer are answered It is replenished in time, ear manuer preferably divides 2 applications, 75~105 kg/hm2 of urea is about applied when 2.5 leaf of remainder leaf number the 1st time, the 2nd is inferior to 1.0~1.5 foliar spray urea of remainder leaf number, 60~75 kg/hm2 can reduce floret degeneration, improve rate of tillering panicle, increase fringe grain Number.

5, disease pest and weed is prevented.Rice covers wheat, and usually serious, mainly white powder by the end of April occurs for banded sclerotial blight and spider by the end of February Disease, followed by aphid.Wheat During Later Period of Growth need to carry out the mixed spray of medicine fertilizer.It is typically chosen the withered spirit of standing grain, flolimat, chlopyrifos, Jing Gang The medicaments such as mycin, triazolone.Rice set wheat weeds in field shares 2 peaks, to going out natural plant height for the 1st before rice harves after Wheat Sowing Peak；After rice harves to early November be the 2nd germination peak.Since rice set wheat root system is completely exposed, to mitigate poisoning, weeding Agent should select galloping horse.Field chemical weed control is added with 6.9% galloping horse, 1.5~1.8 L/hm2 makes its grand 450 mL/hm2 be prevented.
