Abstract

The invention relates to a method for rapid planting of switchgrass in cracked alkaline soil. The invention mainly aims at the problems of high alkalinity, sticky texture, low fertility, low emergence rate of switchgrass and difficulty in planting of cracked alkaline soil, and proposes a cracked alkaline soil method. Rapid establishment of switchgrass. The technical scheme adopted by the present invention is as follows: 1. Laser leveling; 2. Application of improved materials; 3. Organic-inorganic compound fertilizer; 4. Deep plowing and sunning; 5. Irrigation and washing of salt and alkali; 1. Seedling cultivation and transplanting; 8. Field management; 9. Harvesting at the right time; 10. Winter irrigation to preserve moisture. The present invention can realize rapid planting of switchgrass in cracked alkaline soil, and grows well, and can obtain higher biological yield in the year of planting, is suitable for planting switchgrass in cracked alkaline soil in Yinchuan Plain of Ningxia, and is beneficial to the development and utilization of saline-alkali land resources and the production of biomass energy , has significant economic, social and ecological benefits.

Description

technical field [0001] The invention relates to a method for rapid planting of switchgrass on cracked alkaline soil. Background technique [0002] Cracked alkaline soil is a kind of alkalized soil with bad physical and chemical properties. It has high alkalinity, heavy texture and low fertility. Because the surface of this soil is cracked like a turtle when it is dry, it is called "cracked alkaline soil". Ningxia is also known as "white pulp soil". Cracked alkaline soil is mainly distributed in Xinjiang, Yinchuan Plain in Ningxia and the western part of Hetao Plain in Inner Mongolia. [0003] Switchgrass is a herbaceous C4 plant originating in North America. It has the advantages of perennial, strong adaptability, high yield, environmental friendliness, and multi-purpose. It is one of the ideal energy plants. Using a large amount of cracked alkaline soil resources for switchgrass planting can not only realize the biological improvement of this type of land, but also produc...
