Rice machine transplanting dry land tray-free rice seedling raising method

Abstract

The invention relates to the technical field of rice cultivation and in particular relates to a rice machine transplanting dry land tray-free rice seedling raising method. The method comprises the following steps: (1) preparing a rice seedling bed; (2) preparing seed rice; (3) preparing before seeding; (4) seeding; (5) managing the rice seedling bed; and (6) pulling up rice seedlings and performing machine transplanting. According to the method, because the bottom of the rice seedling bed is compacted to form a dense layer, rice seedlings are raised on a part above the dense layer, and a phenomenon that the root system of the rice seedlings grows to penetrate into the dense layer is avoided. Due to the presence of the dense layer, the root system of the rice seedlings grows on the part above the dense layer, the seedlings are easily taken, and the problem that the root system of the rice seedlings is damaged can be effectively solved. In addition, growth of the rice seedlings is not influenced at all, and nutrient, air and water needed by the rice seedlings can freely circulate. Moreover, according to the method, the rice seedling bed is separated in the process of raising rice seedlings by utilizing separators, and later-stage seedling taking and machine transplanting are promoted.

Description

Technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for raising rice seedlings in a machine-transplanted dry land without a tray. Background technique [0002] With the transfer of rural labor, artificial rice seedlings can no longer meet the requirements of my country's social and economic development. The low production efficiency, low labor productivity, and high labor intensity of traditional rice farming techniques based on manual seedling transplanting restrict the development of rice production. In terms of production, there is an urgent need for labor-saving, labor-saving, high-yield and efficient modern rice production technology with mechanized operations as the core, especially rice transplanting technology. In recent years, with the support of policies, my country's rice transplanting technology has developed rapidly. The proportion of mechanized rice planting rose from 4.4% in 2000 to 28% in 2012. However,...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for machine-transplanted rice seedling raising in dry land, which solves the problems of high cost and large investment in raising seedlings in seedling trays. The interface is coiled to prevent the roots of the seedlings from penetrating into the deep soil, and solve the problems of traditional discless seedlings that are difficult to take seedlings and easy to damage the roots.
