Description
One, technical field
The present invention relates to a kind of Ca
2+Signal transduction type saline soil preparation technology and composition proportion are exclusively used in chloride type, sulfate type, carbonate type alkaline land improvement, are beneficial to the recovery and the utilization in above-mentioned saltings.
Two, background technology
Alkaline land improving is a global problem.Saltings, whole world area is about 15,000,000,000 mu, and China ploughs only 1,500,000,000 mu, about 5.4 hundred million mu of saltings area, and wherein saline and alkaline arable land just reaches 0.9 hundred million mu, has become the biggest obstacle of restriction China's improvement of the ecological environment and agricultural sustainable development at present.Meanwhile, along with the large-area reclamation of wasteland in soil, the also former speed development that does not have of the unreasonable irrigation and the soil salinization that water quality deterioration brought.Therefore, the improvement in saltings is the research direction of 21 century agricultural.Research has extensively and profoundly been carried out in the improvement utilization in saltings both at home and abroad for a long time, dropped into a large amount of manpower and materials.Carry out the improvement in saltings with physics, water conservancy, chemistry and biological four kinds of modes, waterways, fresh water flushing, dry farming modify-water are ploughed, are leveled land comprising deep-cutting, applying organic manure, use biological control measure and chemical etc.In the work in the past, bias toward engineering measure, though obtained certain achievement more, but still there are some unsurmountable shortcomings: (1) engineering cost costliness, effect can not be lasting, and the nutrient in the soil of fresh water flushing back is together drained with salinity, the Freshwater resources deficiency is difficult to satisfy pressure salt needs; (2) though salt-tolerant plant has carried out preliminary screening, what do not form system can satisfy the plant variety classification of all kinds saltings, moreover the cultivation difficulty of halophytes is big and the time is long; (3) the comprehensive inadequately and system of the screening of salt tolerant alkali bacterial classification, and not low temperature resistant, can't pass the winter, can not continue breeding; (4) the simple use of chemical modifying measure intermediate ion sorbent material, ionic complexing agent, ion-exchanger, expense height not only, timeliness is short, and sustainable use is low.And the chemical modifying technology of utilizing neutralizing effect only reduces soil alkalescence, but can't stop salt affected soil because of the moisture transpiration accumulation of salt in the surface soil.
Saline and alkaline injury to plant mainly shows as ionic equilibrium imbalance in the plant materials, the osmoregulation imbalance, and separating of ionic destruction, nutritive substance lacks, the physiological metabolism disorder.Ca
2+Participate in all metabolic regulation and control as the intracellular signal molecule, find Ca at present
