Description
Technical field
The present invention relates to a kind of phosphorus method of executing that improves the anti-salt alkali ability of cotton in seedling stage, belong to production technology of crops, fertilizer operation technique field.
Background technology
Northern China hinterland and coastal beach are distributed with a large amount of salination and alkali-affected soil, and be serious to agricultural production harm.Be the crops periods the most responsive to saline and alkaline harm seedling stage, direct result is exactly that seedling lethality height causes the disconnected ridge that is short of seedling, perhaps growing is suppressed, and plant size, breeding time are inconsistent, have a strong impact on field management, population growth, output and economic benefit.
In order to improve the anti-salt alkali ability of crop, forefathers have carried out a large amount of research and development aspect application technology, and these technology can reduce following four types:
One, cultivate by conventional breeding or by genetically modified molecular breeding approach and to resist saline and alkaline crop new varieties or germplasm.At present, conventional breeding (comprise screening and domestication combination, hybridization combine with chemistry or radioinduction etc.) has obtained much to resist saline and alkaline new varieties, Chinese Academy of Sciences Xinjiang ecogeography research institute anti-salt wheat breed " new winter No. 26 ", " new winter No. 34 " of cultivating for example, have stronger anti-saline and alkaline characteristic and tangible high yield advantage (Chinese agriculture information, 2009 05 phases); The research of molecular breeding has obtained a series of patent of invention, mainly concentrates on the acquisition and the conversion aspect (He Yimin, Nian Hongjuan, Chen Li plum plant salt tolerance gene engineering progress, Chinese biological engineering magazine, 2009 03 phases) of anti-salt alkali gene.For example East China Normal University's summer great waves, Xu Kai, flood flat (2005) pass through the strong resistant gene of salt AtNHXS1 of new plant that the DNA shuffling technology obtains, and the methods such as structure, genetically modified plants that recombinant vector is provided to be to use said gene and protein, can cultivate the stronger or other biological of salt resistance and learn the improved genetically modified plants new varieties of proterties (ZL 200810033447.3).
Two,, make crop tide over saline and alkaline tricky time rapidly by external source growth regulatory substances such as exogenous hormone regulation and control seed vitality, the early stage growth fast of promotion seedling.For example, Zhao Kefu etc. have studied a kind of anti-salt drought resistant agent for plant and using method thereof, they press the special ratios prescription with gibberellin, salicylic acid, amino oligosaccharide (O-CMC) or their derivative and calcium salt, be used for soaking seed before the plant seeding, or seedling stage foliage-spray, improve the comprehensive salt tolerant drought-resistance ability of plant (Chinese patent application number 99112463.4).Feng Gu etc. have studied a kind of method and special-purpose soaking liquid thereof that improves halophyte seed germinating potential, the seed of plant is carried out the sharp processing of salt with the mixed aqueous solution that contains sodium chloride, calcium chloride, gibberellin, reach the raising seed vitality, make plant concentrate the purpose (China Patent No. ZL200710121126.4) of sprouting rapidly; The in addition Australian patent application AU-A-81394/75 similar to these patents of invention, french patent application FR-A-2440438 etc.
Three, alleviate saline and alkaline harm by improving the soil.For example, Zhao Lanpo etc. have developed a kind of saline-alkali soil modifying agent and improvement method, reduce the basicity of soil by using aluminum sulfate, thereby improve the output (patent No.: 200410010772) of crop on the alkaline earth.Yao Rongjiang etc. (2006) have reported that application of organic fertilizers, soil conditioner can improve soil structure, make crop yield (Yao Rongjiang, Yang Jingsong, Liu Guangming. the Northeast's saline-alkali soil feature and agro-ecology thereof are administered. soil, 2006 (3): 256-262).
Four, improve the anti-salt alkali ability of crop by the crop genetics measure.Studies show that much improving the salt-resistance of crop in seedling stage by agronomic measures is present the most feasible approach.For example Dong closes loyalty by ridge culture, regulates the Distribution Pattern in soil of salinity, reduces the root system purpose (Dong closes loyalty 2010) of salt concentration, promotion cotton growth on every side thereby reach.
Salt damage suppress one of reason of plant growth be under the high salt condition crop seedling stage root system phosphorus nutrient absorbing ability is reduced.Therefore, the soil available phosphorus concentration that satisfies the neat phosphorus nutrition of crop seedling on saline-alkali soil (is 0.5M NaHCO
3Can extract attitude phosphorus) should be higher than the critical phosphorus supply of normal soil.Yet according to existing cotton culture management mode, phosphate fertilizer is manured into soil as base manure usually.Under the salt damage condition, this soil available phosphorus concentration that technology increased of executing phosphate fertilizer can not satisfy the crop needs.In order to overcome crops seedling stage, be necessary to formulate new fertilizer practice because of the saline-alkaline tolerance that nutritional deficiency caused weakens this difficult problem.
