Water-saving irrigation technology includes

Water-saving irrigation techniques mainly include low-pressure pipeline irrigation, membrane irrigation, sitting water seeding, kiln cellar water-saving irrigation, improved furrow irrigation, etc. 1, low-pressure pipeline irrigation: using pipes instead of earth canals to transmit water, which saves floor space. 2, membrane irrigation: the water flowing in from the seedling release holes is only for the use of the crop, and the utilization rate of water can reach more than 80%. 3, sitting water seeding: a way of localized irrigation while planting. 4, kiln cellar water-saving irrigation: using sky precipitation to accumulate water, and then irrigating. 5, improved furrow irrigation. A way to carry out local irrigation. 4, kiln cellar water-saving irrigation: the use of kiln cellar accumulation of sky precipitation, followed by irrigation. 5, improved furrow irrigation: the long ditch into a shorter ditch, large beds into small beds, usually can save 10-20% water.

Water-saving irrigation -- that is, with less irrigation water to achieve better production efficiency and economic benefits. The basic requirement of water-saving irrigation is to take the most effective technical measures, so that the limited amount of irrigation water to create the best production efficiency and economic benefits.

Vigorously popularize water-saving irrigation technology, to attach great importance to the promotion of agricultural water-saving measures. This can be done by rice dry thinning, seedling throwing, mulching, straw return, deep plowing and loosening, mid-plowing and weeding, suppression, harrowing and weeding, and increasing the application of organic fertilizers and other measures in order to improve the soil's ability to store natural precipitation and moisture retention. Application of chemical water preservation preparations, the introduction and selection of drought-resistant varieties and adjust the crop planting structure is also effective water conservation measures, in the drought and water shortage areas should be vigorously promoted and popularized.

Surface irrigation is the most traditional form of irrigation, including furrow irrigation and border irrigation. This way of irrigation is not uniform, evaporation is large, easy surface soil granular structure, the formation of plate layer, affecting the decomposition of aerobic microorganisms in the soil. This way is watering the ground rather than the crop. However, due to the field engineering facilities are simple and do not require energy, is still widely used.
