Description

Ridge culture planting method of summer soybean in Nanjing area
Technical field
The present invention relates to crop cultivating technology, be applicable to ridge culture planting method of summer soybean in Nanjing area.
Background technology
Soybean [Glycine max (L.) Merr.] is the source of most important vegetable protein and edible vegetable oil in the world today, in world cereal crops formation and the production of international oil crop, occupy critical role, soybean accounts for 35% (Wilcox, 2004) of world's output of oil-bearing crop.
China is the soybean original producton location, and before the 1950's, China is maximum in the world soybean producing country and exported country; but now; Chinese soybean output accounts for world's gross output and is less than 10%, has become maximum in the world importer, the soybean crisis occurs; 2003-2006; the gross yield in Chinese soybean every year fell sharply to 1,440 ten thousand tons in 2007, and import volume increases year by year about 1,700 ten thousand tons; reaching 3,400 ten thousand tons to Chinese soybean import in 2007, is 2 times of China self output.To be subject to market and even political factor influence as if main dependence on import, and have potential collision hazard, therefore increasing production is the only approach that remedies the Chinese soybean breach.
The planting type of soybean is directly connected to the size of its colony, and the size of colony then is the key factor of decision yield per unit area.The basic principle of soybean high-yield cultivation is rationally to utilize and adapting on the basis of natural conditions, the cultivation technique measure of utilization science, to create good light, temperature, water, heat, the fertile condition of soybean fertility, the output and the qualitative inheritance potentiality of soybean varieties are not fully exerted, reach high yield, high-quality, purpose efficiently.Natural conditions generally are uncontrollable, mainly are to deacclimatize by reasonable zoning.Culture technique can be regulated and control, and the essence of culture technique is to improve the influence of ecological factors such as light, temperature, water, heat, fertilizer to soybean physiology course and growing process, thereby improves output and the quality of soybean.
Soybean is different with cereal (except the corn), can not be when being short of seedling adjust the deficiency of density by shooting property, but relies on single-strain grain weight to capture high yield, and full stand is the basis of high yield of soybean.The shrinkage of tatoin seed, shrivelled, grain is heavily low and cause that sprouting power is low, a little less than top native power difference and the seedling gesture; Seed and seedling are fresh and sweet good to eat in addition, subject to the harm of mouse worm.Have only about 90d the breeding time of summer soybean, but whole growing is in the season of high temperature and rainy, and disconnected ridge happens occasionally so summer soybean is short of seedling.Soybean adopts the flat cultivation land for growing field crops of doing to produce and be short of seedling rate more than 10%, and heavier person reaches more than 30%, has a strong impact on summer soybean output.At present, the research of saving the seedling measure about soybean from damage comprises: seed selection and select breeding for use, do well to bask seeds, seed dressing work, meticulous whole ground, sowing date for early sowing, employing seedling raising and transplanting and mulch film cover cultivation etc., yet there are no report for the research of adopting suitable tillage method.
Soybean is flat to be a new soybean high-yield cultivation technology do dense planting, U.S. soybean expert R.L professor Ku Pa forms through the culture technique in surplus 10 years and the research of breeding two aspects, this technology is in the large tracts of land popularization of states such as the U.S., Canada, and the proof obvious effect of increasing production.The compact planting in narrow row volume increase must be a prerequisite with " not producing serious lodging ", must select big of short stem, the semi-dwarf mutant kind of yield potential resistant to lodging, otherwise not only not increase production, and wants the underproduction on the contrary.The Jilin Academy of Agricultural Science Li Ji of crop breeding research institute floods in 2004 etc. are made the dense planting yield-increasing technology and are studied soybean is flat, discovery is of short stem to select for use, anti-, high yield kind implementation compact planting in narrow row is the soybean culture new technology of core, and the conventional ridge culture of production ratio greatly improves.
20th century the mid-80, along with the use of large-scale sower and mechanization farm implements begins to promote precision drilling, to the initial stage nineties begin to promote soybean " ridge three " culture technique, the mid-90 is promoted " narrow row is put down and done dense planting " culture technique, the later stage nineties is promoted " ridge culture compact planting in narrow row " culture technique, and " big ridge dense planting " (135cm ridge 6 row are done) planted experimentally in the part reclamation area at present.Heilongjiang Province in 2008 Bei'an Urban Committee on Agriculture silkworm industry director permitted virtue by continuous 3 years of 2006-2008 at " No. 38, Heihe " soybean varieties at farm, two Longshan planting experiment, the result shows, 90cm ridge culture 4 row dense planting are than the average volume increase 28.4% of 135cm ridge culture 6 row, than the average volume increase 20.6% of 65cm ridge three cultivations.
The ridge planting method is as the summer soybean planting technology, because it is simple to operate, grasp and cost are low easily, save from damage on the seedling measure basis at inheriting tradition, and new development is arranged again.This technology is applied in China the Northeast.The area, Nanjing mostly is summer sowing soybean behind the wheat stubble, and wheat mostly is flat and does, and is to adapt to the traditional planting type of wheat, summer soybean in Nanjing area also with flat as the master.But, cannot say for sure full stand because culture technique do not match.Through research for many years, we think that the main cause that summer soybean in Nanjing area is saved the seedling difficulty from damage is that soil moisture content is difficult to control.By promoting summer soybean ridge planting technology, can effectively improve soil moisture content, improve emergence rate.
