The equipment is reasonable in structural design, the growth environment of alfalfa is effectively improved, the yield of the alfalfa is increased, and the equipment is suitable for mass popularization.

Description

technical field [0001] The invention relates to the technical field of planting in saline-alkali land, in particular to a device and method for improving the cultivation of alfalfa in saline-alkali land. Background technique [0002] Alfalfa is a general name for plants of the genus Alfalfa, commonly known as cauliflower, which is a perennial flowering plant; the most famous of which is alfalfa as pasture. There are many kinds of alfalfa, mostly wild herbaceous plants. There are three main types of alfalfa produced in China. It is very valuable and has the effects of clearing the spleen and stomach, benefiting the large and small intestines, and lowering bladder stones. Alfalfa contains the most abundant vitamin K, which is higher than all vegetables. Others such as vitamin C and B are also quite rich; alfalfa is grown in saline-alkali land It is an effective way to improve the soil environment, but the salt contained in the saline-alkali soil affects the normal growth of cr...

AI Technical Summary

Problems solved by technology

[0003] However, the existing equipment for alfalfa cultivation in saline-alkali land is relatively large in size and complex in structure, which is very difficult to construct; on the other hand, alfalfa grows well in the initial stage of cultivation, but the soil quality cannot be completely improved in the later stage, making it impossible for alfalfa to grow for a long time. Growth, low alfalfa yield, little improvement in soil quality
