Abstract

The present invention belongs to the technical field of soil improvement and specifically discloses a sesbania cannabina and sunflower rotation method for improving soil quality of saline-alkali soil.The sesbania cannabina and sunflower rotation method for improving soil quality of saline-alkali soil comprises the following steps: step one, plowing and fertilizing saline-alkali soil, planting a first season of sesbania cannabina in the saline-alkali soil, conducting plowing for 30-40 cm, then conducting fertilizing, and then conducting ditching and planting the first season of the sesbania cannabina; and step two, watering and irrigating the sesbania cannabina, before emergence conducting irrigating when the soil substrate potential is greater than 5 Kpa, and conducting irrigating when seedlings grow 3 true leaves and the soil substrate potential is changed to greater than 10 Kpa. The design is reasonable. Through the rotation of green manures of the sesbania cannabina and sunflowersand combining a device with an aerobic and pressurized drip irrigation and water and fertilizer integration device to improve the soil quality, the method can achieve improvement of the soil quality of the saline-alkali soil, and is also low in costs, good in sustainability, and high in economic benefits.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for improving the soil quality of saline-alkali soil by crop rotation of quince and sunflower. Background technique [0002] The improvement and utilization of saline-alkali land is a complex system engineering. Different effective improvement measures are formed for different types of saline-alkali land. In summary, there are four main measures, namely engineering measures, physical measures, chemical measures and biological measures. Each measure has its advantages and disadvantages. Some measures have played a certain role in improvement in a short period of time, but they are easy to repeat and cost high. Only a single measure can not achieve good results. Therefore, there is an urgent need for a low-cost, Improvement measures with good sustainability and economic benefits. [0003] For this reason, we propose a method of improving the soil quality of salin...
