Rice direct-seeding drip irrigation under mulch-film dry-farming cultivation method

Abstract

The invention discloses a drip irrigation dry-farming planting method under a rice direct seeding film, which belongs to a crop planting agriculture method. A timely seeding operation is carried out after the preparation before seeding is finished; the seeding operation is as follows: the operations of drip irrigation zone paving, film covering, punching, hole seeding and soil covering on a hole are accomplished by one time by a drip irrigation tube-paving film-paving fine seeder under the film; the drip irrigation zone is arranged on the lower surface of a plastic film and is connected with a water-carriage system; and timely and proper water dripping and fertilizing are carried out according to the growing demand of the crops. The drip irrigation dry farming planting method can be applied to save water by 60 to 70 percent, save the fertilizers by 30 percent, have high degree of mechanization, save labor, reduce the field management and reduce the pesticide pollution.

Description

technical field [0001] The invention belongs to an agronomic method for planting crops in the field of agricultural technology, and more precisely relates to a dry farming cultivation method for rice direct seeding under film and drip irrigation Background technique [0002] Rice is an important food crop in my country. Traditionally, it is mainly planted in flooded paddy fields. my country is one of the 13 water-poor countries in the world, and it is also a large agricultural country. Agricultural water accounts for 70-80% of the total water consumption, especially in drought The agricultural water consumption in semi-arid areas reaches more than 90%, while the total water consumption of paddy fields accounts for more than 65% of agricultural water consumption. Due to changes in the global climate in recent years, spring droughts and summer droughts have occurred frequently, resulting in large-scale production reductions in northern rice planting areas, which seriously hit t...

Problems solved by technology

Because the above-mentioned technology uses ditches to irrigate and the water is exposed, a large amount of water leaks and evaporates to cause waste during the water delivery process. The crops are planted on the ditch box, so that the water and nutrients are not fully utilized, which is easy to cause in northern areas. Soil compaction and salinization; secondly, separate ditching and seedling transplanting, which increases a lot of manual work; one-time application of enough basal fertilizer, can not be precise fertilization, resulting in low fertilizer utilization rate
