Problems solved by technology

[0004] However, in extremely arid and sandy areas, the wind-eroded desertification land has poor soil, arid climate, and severe wind and sand hazards, which are not suitable for the cultivation of oily bean. At present, there is no new planting method to ensure the survival of oily bean in the extremely dry and sandy area. Rate

Embodiment 1

[0033] Taking Tuanjiexin Village, Jiya Township, Hotan City, Xinjiang as the experimental site, this area is located at the southern edge of the Taklamakan Desert, which belongs to the warm temperate continental desert climate, with an annual average temperature of 13.1°C, drought and little rain throughout the year, and an average annual precipitation of 30 mm. The evaporation is as high as 2600mm, the average relative humidity is 41%, and the annual sunshine hours are 2662h. The area is newly reclaimed desert land, and the soil type is aeolian sandy soil.

[0034] Steps of soil preparation: select desertified and degraded land that can implement drip irrigation or newly reclaimed sandy land as the planting plot, and perform rotary tillage twice before sowing, with a depth of 30cm;

[0035] Base fertilizer application steps: Before rotary tillage, apply 1.5 tons of farmyard manure, 20 kg of diammonium phosphate, 20 kg of humic acid and 20 kg of potassium sulfate compound fert...

Abstract

The invention provides a method for planting cyperus esculentus in an extremely arid windy desert area, and relates to the technical field of commercial crop cultivation. According to the planting method, from the aspects of soil preparation, base fertilizer application, sowing, pipe distribution and film mulching, the problems that in the early growth stage of cyperus esculentus, the cyperus esculentus is damaged by wind and sand, and seedlings are difficult to survive are solved. By applying the planting method disclosed by the invention, the plant height of cyperus esculentus, the forage grass yield and the tuber yield can be obviously improved. Meanwhile, after cyperus esculentus ripens, the transfer of surface sand can be effectively inhibited, and the wind erosion harm is reduced. If underground tubers are not harvested, the main purpose is to obtain forage grass, cyperus esculentus can still germinate and grow in spring of the next year after withering in autumn, and the protection effect of cyperus esculentus on wind and sand damage always exists.

Description

technical field [0001] The invention belongs to the technical field of economic crop cultivation, and in particular relates to a method for planting oily bean in an extreme drought and sandstorm area. Background technique [0002] Cyperus esculentus L. belongs to the perennial herbaceous plant of Cyperaceae Cyperus, and the main harvest is underground nuclear tubers. Yousha bean tubers are rich in oil, starch, sugar, protein, dietary fiber, multivitamins and minerals. The oil content of oil sha bean is 20% to 32%, and the yield per unit area is higher than that of soybean, rape, peanut and other oil crops. The yield of underground dried fruit is twice that of peanut and 3 to 4 times that of rape. It is called the king of oil crops. The stems and leaves of oily bean are rich in nutrients and are also excellent feed. Fresh grass can be directly eaten by herbivores, such as cattle, sheep, horses, rabbits, geese, etc.; dried grass can be used as an auxiliary formula for feed a...
