Furrow type rice fixed throwing cultivation method

Abstract

The invention discloses a furrow type rice fixed throwing cultivation method. The method includes the steps: dividing a rice field into a plurality of plots equal in width, and partitioning each two adjacent plots by a furrow; arranging a seedling rope with a hill spacing mark in the middle of each plot; and performing throwing planting by a person standing in the corresponding furrows, throwing n lines of seedlings in each plot from one side of each seedling rope to the plot edge on the other side, and when (n+1) / 2 lines of seedlings are thrown, throwing (n-1) / 2 lines of seedlings from the position, one line away from the seedling rope, on the other side. Accuracy of longitudinal distance of the seedlings is improved by using the seedling ropes for providing scales for the longitudinal distance of the seedlings. Each plot is divided into two portions in width by the seedling rope, the transverse distance for throwing planting of the seedlings at a time is decreased, and two sides of the plots and the seedling ropes are regarded as reference substances in the width direction respectively, so that accuracy of the transverse distance of the seedlings is improved. The furrow type rice fixed throwing cultivation method solves the problem of lack of corresponding uniformity numerical range definition due to the fact that rice throwing planting line nest distance is determined mainly by depending on manual visual observation.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a furrow-type fixed-throwing cultivation method for rice. Background technique [0002] Seedling throwing cultivation is a major reform in rice farming technology. It mainly uses the gravity of the seedlings to carry the soil, and the seedlings are planted in the field through throwing and throwing. It is a cost-effective and efficient planting technology. In recent years, seedling throwing technology has been innovated and developed in our country, and its promotion and application area is also increasing day by day. However, as far as the current seedling throwing methods are concerned, most of them adopt the conventional "starry sky" method. Although this method is time-saving Labor-saving and other advantages, but due to the roughness and randomness of the operation, it also has many defects: unstable yield, low uniformity of seedling distribution, low population qua...

Problems solved by technology

[0008] In view of this, the present invention provides a furrow-type rice fixed-throwing cultivation method to solve the problem of lack of corresponding uniformity numerical range definition due to the fact that the determination of the nest spacing of rice throwing planting mainly depends on manual visual inspection.
