Blocking or bunching, an agrotechnical method consisting of the mechanized thinning of wide-row plantings and leaving in the row “bunches” of several plants at a uniform distance from one another. The method is used for cultivating furrow-plowed crops such as sugar beets and maize. Blocking is usually done with a harrow across the rows; after a day or two the bunches are made sparse and the required number of plants is left in them. Blocking decreases the amount of labor lost in thinning plants. In square-nest sowing, blocking is not necessary. blocking1. Pieces of wood used to secure, join, or reinforce members, or to fill spaces between them. 2. A method of bonding two adjoining or intersecting walls, not built at the same time, by means of offsets whose vertical dimensions are not less than 8 in. (20 cm). 3.
