Abstract

The invention relates to a method for planting apocynum venetum in an arid area salinification desert. In the method, trickle irrigation facilities are overlaid in the salinification soil environment, hollow billet trickle irrigation zones are distributed in the mode of one tube in one row; apocynum venetum seeds are planted on two sides of the hollow billet in a strip cropping mode; straws are covered in the sowing zone, and water is dripped in time to reduce evaporation loss and save water resource; the water-saving irrigation technology is utilized to create the low-salt environment for apocynum venetum seeds to bud and young seedlings to grow; and the young seedlings are built. According to the method disclosed by the invention, inhibition on pocynum venetum seed germination and young seedling growth is overcome, the complex process of transplanting the pocynum venetum seedling raising is overcome, the pocynum venetum can be planted on a large scale, and therefore the technical reserve is accumulated for developing and utilizing large-area saline-alkali soil wasteland in the arid area.

Description

Technical field: [0001] The invention belongs to the field of plant cultivation and relates to a method for planting apocynum apocynum in a salinized desert in an arid area under the condition of drip irrigation. Background technique: [0002] Saline-alkali land is widely distributed in Xinjiang. Affected by the arid climate and closed inland basins, the saline-alkali land in Xinjiang has the characteristics of large area, many types, heavy salt accumulation, and complex formation. The total area of ​​saline-alkali soil in Xinjiang is 8.476×10 6 hm 2 , 31.1% of the existing cultivated land is affected by salinity. Xinjiang is an important strategic reserve area of ​​reserve cultivated land resources in the country, and the main body of reserve cultivated land resources suitable for development is saline desert. Under the circumstances of increasing population and decreasing cultivated land area, the scientific and efficient development and utilization of saline-alkali la...
