Abstract

The invention belongs to the technical field of agriculture and relates to a foliar fertilizer for growth of sweet potatoes. The technical scheme includes that the foliar fertilizer is prepared from, by weight, 1 part of monopotassium phosphate, 0.8-1.5 parts of potassium nitrate, 0.8-2 parts of chitosan and 0.5-1 part of humic acid. The foliar fertilizer has advantages that synergistic effects are achieved due to matching of components in a composition according to a specific proportion, growth of the sweet potatoes is promoted, and yield is increased.

Description

technical field [0001] The invention relates to a foliar-sprayed fertilizer for growing sweet potatoes, which belongs to the technical field of agriculture. Background technique [0002] Sweet potato is a healthy and delicious food. Sweet potato is full of treasures. Not only sweet potato can be eaten, but also sweet potato leaves and stems can be made into delicious food. Regular consumption of sweet potatoes can lower blood sugar and blood lipids. In recent years, the health value of sweet potatoes has attracted more and more attention. There is even a saying that sweet potatoes can be compared with ginseng. [0003] Although sweet potatoes are resistant to barrenness, they have a long growth period, strong fertility, and consume a lot of nutrients in the soil. Therefore, on the basis of applying enough base fertilizer, it is necessary to apply a certain amount of foliar fertilizer to increase the yield, especially after the sweet potato enters the late growth period, the...
