Abstract
The invention discloses a method for solving the soil alkalization problem with assistance of mesembryanthemum-crystallinum crop rotation. The method includes the following steps that an organic substrate is prepared from fermented sasangua cakes, lime, fermented oil cakes, decomposed straw and decomposed livestock manure; sasangua cakes, oil cakes and straw are composted, fermented and decomposedfor 20 days to 30 days, and the livestock manure is composted, fermented and decomposed for 35 days to 45 days; seedlings of mesembryanthemum crystallinum are cultivated in August to September, and the seedling stage is 30 days to 35 days; in protected areas, 1,500 kg of auxiliary materials per mu are broadcasted in a greenhouse; the size of open boxes of the protected areas is 1.2 m to 1.4 m, and the planting row spacing is 30 cm*40 cm. According to the method, the certain control effect on the greenhouse continuous cropping obstacle of soil alkalization is achieved, the mesembryanthemum crystallinum is used as a crop rotation variety, sodium in soil is efficiently absorbed, and the high content of soil sodion can be released while growth and development of the mesembryanthemum crystallinum are facilitated; compared with other methods, the method is simple and easy to operate and obvious in effect.
Description
technical field [0001] The invention relates to a vegetable cultivation technology, in particular to a method of ice vegetable rotation aiming at soil salinization. Background technique [0002] Soil salinization (soil salinization) refers to the natural geological process in which salt continuously accumulates to the soil surface to form saline soil. Saline soil is formed under certain natural conditions such as climate, topography, land, hydrogeology, etc. Human activities, historical floods, floods, and droughts, changes in river courses, and land use, agriculture, and water conservancy technical measures have also had a major impact on the occurrence and development of soil salinization. [0003] Generally, the soil with a soluble salt content greater than 0.1% within a thickness of 0.2 m of the soil layer is called saline soil. Soil salinization is divided into two types: salinization and alkalization, so it is also called soil salinization. When the neutral salt con...
