Soil improvement method for planting maize in tea field

Abstract

A soil improvement method for planting maize in a tea field is implemented based on the steps as follows: one, removing branches and leaves from the tea field, and spraying a destuctive herbicide for one time; two, digging a ridge trench beside each row of tea tree roots; three, dibbling maize seeds in the ridge trenches; four, applying fertilizers between every two maize seeds; five, back ridging the ridge trenches in order to bury the maize seeds and the fertilizers; six, spraying a Dicotyledones herbicide in the growth process of maize seedlings in order to kill the newly grown tea buds; and seven, applying fertilizers to the maize periodically. The soil improvement method for planting maize in tea field uses a simplest method to improve the field where tea trees are planted for years into the field for planting maize. The old tea tree roots in the tea field are rotten and used as the fertilizer for the maize, thereby saving a plenty of labor and fertilizer, getting a good harvest of maize, and improving the soil texture very well.

Description

technical field [0001] The invention relates to a land improvement method for changing the land where tea has been planted for many years into corn, and belongs to the field of agricultural technology. Background technique [0002] Tea trees are perennial dryland crops. After many years of planting tea trees in the same land, the soil properties of this land are no longer suitable for planting tea trees. If you continue to plant tea trees, the yield will become lower and the fertilizer required will be greatly reduced. Therefore, the tea fields must be replanted with other crops to improve the properties of the soil. However, it is not easy to suddenly change the land where tea trees have been planted for many years to other crops, because the old tree heads in the field are very hard and firm, and unless there are large-scale mechanical plowing, it is difficult for ordinary small-scale farming machinery to plow the land. Farming, even if you can barely plow the land, clear...

Problems solved by technology

To change the tea field to plant corn, the general method used by farmers is to clean the branches and leaves of the newly harvested tea field, dig out the tree tops, clean out the old tree tops, and then plow the land, and then p
