Problems solved by technology

Due to its unique technical advantages, trace irrigation has a wide range of application prospects, especially for intensive farming and dry farming in areas with arid and harsh climates. However, trace irrigation technology has only been used in facility agriculture and fruit and vegetable greenhouses so far. However, it has not been used in field cotton planting in the arid desert area of ​​Northwest China. Therefore, it is imperative to explore a complete set of cultivation methods suitable for trace irrigation, water and fertilizer integration and high-efficiency cotton planting in this area.

Embodiment 1

[0112] Embodiment 1: Adopting the high-efficiency cultivation method of cotton trace irrigation, water and fertilizer integration in arid desert area, proceed according to the following steps: the first step, soil preparation and fertilization; the second step, the setting of trace irrigation system and the formulation of irrigation system; the third step , film-covered seeding; the fourth step, seedling management; the fifth step, chemical regulation.

[0113] As shown in the figure, the trace irrigation system of Example 1 is set up, including a water well 1, a water pump 2, a main water supply pipeline 3, a water supply capillary 4, a return water pipeline 6, a water discharge valve 7, and a water pressure gauge 8. It is characterized in that, the pipe laying machine is used to lay pipes, the main water supply pipe 3 and the water supply capillary pipe 4 are buried at a depth of 30cm, and the row spacing of the water supply capillary pipe 4 is 76cm (L 2 ), that is, in the m...

Embodiment 2

[0115] Embodiment 2: adopt the high-efficiency cultivation method of cotton trace irrigation water and fertilizer integration in arid desert area, carry out according to the following steps: the first step, soil preparation and fertilization; the second step, laying drip irrigation pipes and formulating irrigation system; the third step, covering Membrane seeding; the fourth step, seedling management; the fifth step, chemical regulation.

[0116] The trace irrigation system of Example 2 is set up, including a water well 1, a water pump 2, a main water supply pipeline 3, a water supply capillary 4, a return water pipeline 6, a water discharge valve 7, and a water pressure gauge 8.

Abstract

The invention discloses a cotton trace irrigation, water and fertilizer integrated efficient cultivation method in arid desert areas. The method sequentially includes the steps of land selection, arrangement of a trace irrigation system, soil preparation, seed selection, seed processing, film mulching and sowing, field water and fertilizer regulation, disease and insect pest prevention, chemical regulation, and harvesting at proper time. The method is characterized in that the core of the technology is that cotton film mulching and sowing and underground trace irrigation, water and fertilizer integration make roots of cotton in a moisture and nutrient absorbing state all the time in the growth period; meanwhile, surface evaporation is reduced, water and fertilizer resources can be reasonably and efficiently utilized, and field management comprises irrigation, topdressing, disease and insect pest prevention and the like. By the adoption of the trace irrigation, water and fertilizer integrated efficient cultivation method, water and fertilizer management is carried out on underground root layers, surface evaporation is reduced, the nutrient loss is reduced, and the water and fertilizer utilization efficiency is greatly improved; compared with the prior art, the water utilization rate can be increased by 30-40%, the ecological environment is protected, the cotton yield is effectively increased, and the effects of high yield and high efficiency are achieved.

Description

technical field [0001] The invention relates to a crop cultivation method, in particular to a high-efficiency cultivation method for cotton trace irrigation, water and fertilizer integration in arid desert areas, and belongs to the technical field of plant cultivation. Background technique [0002] Cotton is one of the most important fiber crops in the world. As a strategic material, it plays a pivotal role in the national economy. my country is the largest raw cotton producer as well as the largest consumer. The domestic demand for cotton is more than 10 million tons, and the self-sufficiency rate is only about 70%, and the contradiction between supply and demand is becoming increasingly prominent. In addition, due to factors such as the reduction of arable land, food security, and the price ratio of grain and cotton, it is impossible for my country's cotton area to increase significantly. The most serious problem is that domestic cotton production has caused the cotton are...
