Abstract

The invention relates to a method for constructing a yam irrigation mode in sandy land, including yam cultivation investigation, yam ditch irrigation section mode function design, and yam ditch irrigation section optimization. Among them, the work process of yam cultivation technology investigation is the determination of cultivation season, site selection and fertilization, fertilizer and water management, erection and pruning and harvesting; yam ditch irrigation section mode function design According to the geometric programming method, the objective function model is constructed to increase the income, and the construction suitable for sandy land is constructed. The objective function of the geometric planning of furrow irrigation of Chinese yam is solved according to the corresponding constraints. Experiments have proved that the invention has strong functionality, simple, effective, low-cost technology, and significant benefits of increasing income and reducing disasters, and can be widely used in sandy yam planting areas.

Description

technical field

[0001] The invention relates to the technical field of agricultural economic crop planting and irrigation, in particular to a construction method of a sandy yam irrigation mode. Background technique

[0002] The requirements of yam for the growth environment are not too harsh, and the adaptability is strong. Yam likes warm temperature and can tolerate cold. But planting yam can not be waterlogged or drought, can not be waterlogged. The above-ground stems and leaves of Chinese yam are warm and afraid of frost, and the more suitable cultivation temperature is 25 to 28 degrees Celsius; the suitable temperature for tuber germination is about 15 degrees Celsius, and at 20 to 24 degrees Celsius, the tuber grows the most. Rapidly, but when the temperature is below twenty degrees Celsius, the growth of tubers is hindered. The growth of tubers requires sufficient sunlight, which is suitable for tubers to accumulate nutrients. Planting yam is suitable for sunny, fl...
