Method for raising seedlings in mud for mechanical transplanted rice fields

Abstract

The invention provides a method for raising seedlings in mud for mechanical transplanted rice fields, and belongs to the technical field of agricultural production. The method for raising seedlings inmud for mechanical transplanted rice fields comprises the steps of: cultivating a part of a rice field for preparing mud; laying mud in seedling beds; conducting fertilization and laying seedling-raising trays; conducting sieving and loading mud; conducting sowing and slightly pressing rice seeds; and conducting dry raising and strengthening seedlings. In the method, a mini-sized machine is usedto plough and prepare the land in a cultivation area in advance, the mud is prepared, then a layer of the mud is laid on a non-cultivation area to prepare a hard seedling plate with a compact lower part and a loose upper part before seedling raising, porous hard seedling-raising trays are laid on the surface of the seedling plate after fertilization, and a partition layer is laid at the bottom ofeach seedling-raising tray for facilitating root growth. Small stone and debris in the mud are removed by filtration of a steel mesh screen, and then the trays are loaded with seedlings for raising, thereby solving the problem of uneven emergence of seedlings caused by uneven mixing of mud and fertilizers and uneven spreading of seedling-strengthening agents, improving the mud structure in the seedling-raising trays, promoting root growth and facilitating regulation and control on seedlings and cultivation of strong seedlings.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for machine-transplanted paddy field mud seedling raising. Background technique [0002] Rice mechanized planting is the development direction of my country's rice farming technology, which is conducive to reducing labor intensity and improving rice production efficiency. Cultivating strong seedlings is the key to the development of machine-transplanted seedlings. Paddy-field mud-raised seedlings are the main method of machine-transplanted seedlings in southern my country. Compared with seedling raising on dry land, mud seedling raising can be directly taken from paddy field mud for seedling raising because it eliminates the need for seedling raising soil collection, transportation, soil drying, soil sieving, disinfection and fertilization, etc. It is easy to operate and saves seedling raising costs. It is widely used in the south . The traditional rice...

AI Technical Summary

Problems solved by technology

The traditional rice machine transplanting mud seedling raising method is used to make seedling boards. About 7 days before sowing, soak the seedling field with water, then use a rotary tiller to plow it 2-3 times, combine with fertilization, and start making seedling boards and seedling grooves after sinking. Medium operation, inconvenient operation, is not conducive to dry seedling raising in paddy fields after emergence; at the same time, due to fertilization of the entire seedling field, the fertilizer loss is serious, which is easy to pollute the paddy field and affect the emergence of seedlings; generally, the mud is directly placed on the plate, and there is no good mud filtering method. Impurities such as stones are difficult to filter and remove, and the seedling needles will be damaged during machine transplanting, which will affect the machine transplanting operation; at the same time, the mud moisture content is high, the soil is heavy, and the water permeability is poor. Poor quality and other problems, and it is difficult to sieve the paddy field mud to remove stones, sundries, etc. Direct seedling raising may easily cause damage to the seedling needles during machine transplanting

These factors make it difficult to cultivate strong seedlings in mud seedling raising, and the quality of seedlings is poor, which affects the yield of machine transplanting

At the same time, the whole field of seedlings is plowed to make seedling borders and moist seedlings, which is inconvenient to operate in the field
