Study on Irrigation Pattern in Conservation
The conservation tillage was dryland agriculture technique. But Xinjiang is the irrigation farming, the problem of irrigation was main problem when the conservation tillage was used. Our objective was to study conservation tillage and find three patterns of conservation tillage. The conservation was dryland agriculture technique, which under the agricultural production condition develops. The various countries promotion conservation tillage is the establishment dryly is being used as above the agricultural basis, north part of our country various conservation tillage also is in exempts ploughs sowing seeds, the soil deep pine and the straw stalk cover and so on dryland does saves water in the technical foundation to develop. Dryly is making the area, the conservation tillage is a quite mature agriculture tillage technique, because is protecting and saves the land resource, sharpens the agricultural synthesis productivity and synergize the aspect effect to be remarkable, thus obtains the national policy the support, deeply farmers welcome, in recent years is promoted the implementation area unceasingly to increase, the Ministry of Agriculture project model district conservation area has only surpassed 20 million Chinese acres. Xinjiang is the Eurasia center, the extreme dry few rain, the annual mean rainfall amount is only 145mm, is the model the oasis irrigation farming, 80％ above cultivated land must depend on the surface irrigation. With dryly makes the agriculture to compare, the ditch is the construction and to the ground smoothness request, enhanced the irrigation farming production cost, imperceptibly increased the implementation conservation difficulty. As a result of the traditional irrigation form and the fact conservation, has formed the Xinjiang characteristic conservation tillage system is the irrigation farming conservation tillage system. Whether can theeffective solution irrigation question, be the protection culivationtechnique whether can obtain one of big area promotion implementation aspects in Xinjiang. Looking from the nation that, under my area research irrigation farming condition protection culivation technique, the exploration establishes the Xinjiang conservation theagricultural irrigation pattern, has the certain typical nature and the representation, therefore, in 2005 I the area conservation tillage agricultural irrigation pattern research topic, isincluded Ministry of Agriculture (2005-2007 year) the conservation tillage technique innovation project. For two years, the union project implementation, carry on the contrast to experiment and to study the analysis, obtain the following enlightenment:
