In recent years, in order to effectively solve the problems such as farmland-use water amount is excessive and the farmland-use water level of resources utilization is low, perhaps
More areas introduce the irrigating facilities such as trickle irrigation, micro- spray in Wheat in Field corn-growing regions.But lacks and meet the practical need of crop
The mating irrigation strategy of water rule, for actually planting situation, the irrigation management of wheat, even if there is the case where irrigating facility
Under, still based on Conventional wisdom, i.e., key developmental stages carry out enough quotas moisture supply, way to manage is extensive, blindly with
Machine is big.
The irrigation method of above-mentioned wheat is primarily present following problems: 1, the property planned as a whole is insufficient: the moisture supply of enough quotas makes
Crop root zone water storage is obtained in a saturated state, less absorption underground water, therefore wheat harvesting corn for quite a long time
After plantation, growing area enters rainy season, and root zone water storage increases, easily formation deep percolation, polluted underground water；2, unbalanced supply-demand: foot
The water supply-demand equilibrium of amount quota has ignored the practical water consumption situation of crop and every total rainfall per year and drop under DIFFERENT METEOROLOGICAL CONDITIONS
Rain Annual distribution otherness large effect, it is difficult to realize that moisture supplies to give the accurate matching of crop water, water-saving result is unknown
It is aobvious；3, water use efficiency has to be hoisted: traditional enough quota water supply-demand equilibriums, and water irrigates excessively abundance, after irrigation
Quite a while, there is luxurious rising phenomenon in crop root, or even form rainwash, not give full play to drip irrigation system
Advantage, water use efficiency are low.In fact, in order to solve problem above, it should in winter wheat Key of the yield increasing breeding time, as far as possible
Irrigation rate is compressed, coordinates the equilibrium of supply and demand, water use efficiency is further increased while emptying groundwater reservoir.Therefore, needle
To under condition of drip irrigation, Winter Wheat Water management method extensive at present is needed to propose a kind of scientific and reasonable irrigation strategy, be established
Optimal irrigation program, maximizes water use efficiency at the case where avoiding " cross fill " and " owing filling ".
